ASTM D7032 28 MPa Flexural ku mabati yo mu bwoko bwa Pisine y'ubucuruzi: Icyo igenzura ry'ibipimo

1. Impamvu ASTM D7032 ari yo ngamba y'umurinzi w'irembo mu bijyanye no gupakira amadirishya yo mu bwoko bwa pisine y'ubucuruzi

ASTM D7032, yasohotse na ASTM Mpuzamahanga, ni cyo gipimo cy’ibanze ku isoko rya Amerika y’Amajyaruguru ndetse n’irya WPC ku isi hose. Iri hame ryashyizweho kubera ko ukwiyongera kwihuta kwa composite decking mu ntangiriro za 2000 kwatumye habaho icyuho cy’ubwiza: hatabayeho ibisobanuro bihuriweho, specifiers nta buryo bwizewe zari zifite bwo kugereranya ibicuruzwa biva mu nganda zitandukanye. ASTM D7032 yujuje icyo cyuho igena amanota y’imikorere ntarengwa ku mbaraga zo guhindagurika, gukurura fasteners, kudakomera, kudahindagurika kwa UV, kwinjiza ubushuhe, no kudahindagurika.

Ku byerekeye intebe z'ubucuruzi, inyungu ziba nyinshi cyane kuruta izikoreshwa mu gutura mu ngo. Intebe rusange ya pisine muri hoteli cyangwa resitora ishobora kwakira abantu 500 kugeza ku 2.000 ku munsi mu gihe cy'ibihe by'ubushyuhe. Intebe, intebe zo kuraramo, ibikoresho by'amapine, n'imiti iterwa n'amazi ashyushye aturuka mu duce twa chlorine cyangwa umunyu bitera imitwaro n'imihangayiko iyo intebe y'amazu itigeze ihura na yo. Bityo, abagena ibikoresho bakoresha ASTM D7032 nk'icyunguruzo mbere yo kwemeza ko ibicuruzwa byujuje ibisabwa: niba ibicuruzwa bidashoboye kugaragaza ko byujuje ibisabwa, bikurwa mu giciro mbere yuko habaho ibiganiro ku giciro. Niyo mpamvu buri kintu cyose gikomeye Uruganda rwa Wpc isohora amakuru y'ikizamini cya D7032, n'impamvuYego yashyize ahagaragara raporo z'ibizamini bya SGS ku mpande zombi kuva yashingwa i Ningbo mu 2010.

Ingano y'imbaraga zo guhindagurika ya MPa 28 yavuzwe muri D7032 ni ingenzi cyane ku mabaraza yo mu gishanga. Imbaraga zo guhindagurika—ubushobozi bw'ikibaho bwo kudapfunyika munsi y'umutwaro—ni bwo bugena neza uburebure bw'aho amabaraza ashobora guhagarara, uburemere bungana ikibuga gishobora kwihanganira, ndetse niba imbaho ​​zizagira impinduka zihoraho uko igihe kigenda gihita. Umuntu usuzuma urutonde rw'amabaraza yo mu gishanga cya metero kare 1,000 azagereranya buri gicuruzwa gikenewe n'uyu mubare mbere na mbere, kuko ashingira ku mibare yose y'ubuhanga. Ibicuruzwa byujuje cyangwa birengeje MPa 28 bishobora kugaragazwa neza ku mabaraza asanzwe ya mm 400; ibyo bidahagije bisaba intera iri hagati y'amabaraza n'igiciro cyo hejuru cy'inyubako.

2. Gusobanukirwa ibisabwa ku mbaraga zo guhinduranya za MPa 28

Imbaraga zo gucika, kandi zitwa modulus of rupture (MOR), zipima umuvuduko ntarengwa ikibaho cya WPC gishobora kwihanganira mbere yuko kivunika mu igeragezwa ryo gucika. ASTM D7032 references ASTM D790 nk'uburyo bwo gukora. Mu buryo busanzwe, urugero rw'ikibaho cyo ku meza gishyirwa ku nkunga ebyiri, maze umutwaro ugashyirwa hagati kugeza igihe icyitegererezo kinaniranye. Agaciro k'umuvuduko uvamo, kagaragazwa muri megapascals (MPa), ni imbaraga z'umuvuduko w'igicuruzwa.

Ingano nto ya 28 MPa muri ASTM D7032 igaragaza ubushobozi buke bwo gutwara imizigo bukenewe ku kibaho cyo ku meza kugira ngo gishyigikire uburemere bw'amaguru, ibikoresho byo mu nzu, n'ibikoresho byo kubungabunga rimwe na rimwe ku cyuho gisanzwe. Ku bijyanye n'ibicuruzwa byo mu mazi, abapima bakunze kongeramo ingano y'umutekano, bagasaba 30 MPa cyangwa irenga kugira ngo babaze imizigo ihindagurika iva ku bantu benshi n'ibikoresho byo mu mazi biri ku mapine. Ydwpc's YD150RH30 classic decking profile isuzuma buri gihe hejuru ya 28 MPa mu isuzuma rya laboratwari ryemewe na SGS, mu gihe YD140RH23 co-extrusion profile, ifite umupfundikizo wayo munini wa polymer, itanga imikorere yo kuzunguruka ku mpera yo hejuru ya WPC.

Ku muntu upima metero kare 1.000 z'aho bashyira pisine, umubare w'imbaraga zo guhindagurika kw'imashini na wo utuma intera y'imashini ishyirwa mu mapine irushaho kuba nziza. Ikibaho gifite ubushobozi bwa 28 MPa gishobora gukenera intera ya mm 350 hagati y'ikibaho mu gihe cy'imitwaro y'ubucuruzi, mu gihe isuzuma ry'ikibaho kuri 32 MPa rishobora gusobanurwa kuri mm 400. Hejuru ya metero kare 1.000, iryo tandukaniro rya mm 50 risobanura kugabanuka gushoboka mu bikoresho byo guhagarara n'umurimo wo gushyiraho. Niyo mpamvu abapima neza bagereranya agaciro nyako k'ibizamini kandi bakabishyira mu miterere y'umushinga wose. Ydwpc itanga icyemezo cyuzuye cy'ibizamini byo guhindagurika kw'imashini kuri buri koherezwa kugira ngo gishyigikire iri sesengura.

3. Guhindura imiterere y'umuzigo: Impamvu imikorere y'umuzigo w'igihe kirekire ari ingenzi ku madirishya yo mu bwato

Nubwo imbaraga zo kuzunguruka zibwira umuntu ugena ingano y'umutwaro ikibaho gishobora kwihanganira mu gihe cyangiritse, kuzunguruka kw'umutwaro bigaragaza ibiba mu gihe cy'imitwaro ihoraho mu mezi n'imyaka. ASTM D7032 irimo ibipimo byo gupima umutwaro kuko ibikoresho bya WPC biba bito cyane: bihinduka buhoro buhoro kandi buhoro buhoro mu gihe cy'umutwaro uhoraho. Ku gice cyo ku ruziga rw'ubucuruzi, uyu mutwaro uhoraho uturuka ku bikoresho bihoraho - amasanduku yo gutera, inkingi, intebe zihamye, amazu y'ibikoresho byo ku ruziga - no ku rujya n'uruza rw'abantu benshi mu masaha y'akazi.

Ikizamini cya D7032 cyo gukurura gitanga icyitegererezo cy’ikibaho ku mutwaro uhoraho mu gihe runaka ku bushyuhe n’ubushuhe bugenzurwa. Kurenza iki gipimo ntarengwa cyemewe cyo gukurura bigenwa ugereranyije n’igihe ikibaho gikoreshwa, kandi kurenza iki gipimo ntarengwa bivuze ko ibicuruzwa bitagera ku gipimo cyo gukurura. Ku madirishya yo mu bidendezi by’ubucuruzi, ibidukikije byongerwa n’ubushuhe bwinshi n’ubushyuhe busanzwe busanzwe mu bikoresho byo mu mazi. Amadirishya yo mu bidendezi byo muri Dubai cyangwa muri Singapuru agira ubushyuhe buri hejuru ya dogere selisiyusi 35 mu gihe kinini cy’umwaka, ibyo bikaba byihutisha urujya n’uruza rwa viscoelastic muri WPC matrices.

Ydwpc ikemura imikorere yo gucikagurika binyuze mu kugenzura uburyo bwo gukora. Ingano y'ibiti, urwego rwa polymer, ibikoresho byo guhuza, n'ibipimo byo gutunganya byose byatunganyijwe kugira ngo bigabanye gucikagurika kw'igihe kirekire. Icyitegererezo cya YD140RH23 co-extrusion cyungukira ku gishishwa cyacyo cya polymer kirinda, gikwirakwiza imizigo y'ubuso ku buryo bungana mu gice cy'urukuta, bigagabanya uburemere bw'imihangayiko aho gucikagurika gutangirira. Abapima bashobora gusaba ibyemezo by'ibizamini bya creep bigaragaza ko gucikagurika neza mu rugero rwa D7032, ndetse no mu gihe cy'ubushyuhe bwinshi. Aya makuru ni ingirakamaro ku bahanga mu gushushanya amadirishya yo mu bidendezi mu turere dushyuha aho guhitamo ibikoresho byo ku meza ni ingenzi cyane ku mikorere y'ikigo mu gihe kirekire.

4. Gukurura no Guhuza Ibikoresho by'Insinga

Ikibaho cy’inyuma cy’ikibaho cyizewe gusa nk’aho gifatanye n’inyubako. ASTM D7032 ikemura iki kibazo binyuze mu igerageza ryo gukurura imbunda, ripima imbaraga zisabwa kugira ngo ukuremo vis cyangwa imbunda ku kibaho mu gihe hagenzuwe. Ku mabaraza y’ibiraro by’ubucuruzi, kudakura imbunda ku kibaho ni ikintu cy’ingenzi mu mutekano: amabara adakora neza atera ibyago byo kugwa, kandi mu gihe cy’amazi yo mu kiruhuko cy’amazi, ikibazo cyo kugwa no kugwa gitera ingaruka zikomeye. Ababisobanura rero bafata agaciro k’imbunda ya D7032 nk’aho ari ngombwa kugenzura.

Uburyo bwo gupima bukubiyemo gushyira vis zisanzwe mu kibaho ahantu hagenwe no gushyira imbaraga zo gukurura ku ruhande rw'ikibaho kugeza igihe igifunga gikuruye. Imbaraga nke zo gukurura muri D7032 zigenzurwa hakurikijwe ubucucike n'ubunini bw'ikibaho, bigaragaza imitwaro yitezwe ituruka ku rujya n'uruza rw'amaguru, umuyaga uzamuka, n'ubushyuhe bukwirakwira. Ikibaho gifite ubucucike buke cyangwa imigozi idakwirakwira neza kizagaragaza ko igifunga gifata nabi, bigatuma kigenda kandi amaherezo igifunga kikananirwa mu gihe cy'ingendo zo kunywesha no kumisha zisanzwe mu bidendezi.

Uburyo Ydwpc ikora butuma habaho ubucucike buhoraho mu gice cyose cy’urubaho, ari na cyo kintu cy’ingenzi kigena imbaraga zo gukurura ibipfunyika. Udupapuro twa kera twa YD150RH30, dufite uburebure bwa mm 30, dutanga uburebure buhagije bw’ibikoresho byo gushyiramo imisumari, mu gihe YD140RH23 ikoresha uburyo bwo gukurura ibipfunyika inyurwamo n’urukuta rurerure rurwanya gukururwa n’ibipfunyika. Ibicuruzwa byombi bigeragezwa hakoreshejwe uburyo bwo gukurura ibipfunyika buhishe hamwe na vis-stainless steel bikunze kugenwa mu gushyiraho pisine y’ubucuruzi. Abakoresha ibyuma bipima metero kare 1,000 bashobora gusaba amakuru y’ibizamini byo gukurura ibipfunyika nk'igice cy’ipaki y’ibizamini bya Ydwpc, hamwe n’ingengabihe y’ibipfunyika isabwa hakurikijwe ibisabwa mu gace k’umuyaga.

5. Kurwanya ubushuhe n'ibinyabutabire mu bidukikije byo mu mazi

Amadirishya yo mu bidendezi by'ubucuruzi ahura n'ibibazo byihariye by'ubushuhe burenze ubwo mu yandi madirishya yo hanze. Amadirishya ahura n'amazi ahora asukwa, ubushuhe bwinshi bwo mu kirere, amazi ahagaze, n'imiti isukura irimo chlorine, bromine, na algaecides. ASTM D7032 irimo isuzuma ry'uburyo amazi yakwinjira mu kirere no kubyimba kugira ngo harebwe uko ikigega cya WPC gikemura ibi bibazo. Isuzuma risanzwe ryerekana uburyo amadirishya asukwa mu mazi aho ingero z'amadirishya zijugunywa mu gihe runaka, kandi kwiyongera k'uburemere n'impinduka bipimwa hakurikijwe imipaka ntarengwa yemewe.

Ku bapima imiterere y’aho amazi aherereye ku buso bwa metero kare 1,000, amakuru ajyanye no kwirinda ubushuhe ni ikintu cy’ingenzi gitandukanya imirongo y’ibicuruzwa. Imiterere ya kera ya WPC nka YD150RH30 ifite ubuso bw’ibiti bukozwe mu nsinga bufata ubushuhe bufata ubushuhe ku kigero kiri hejuru kurusha imiterere yakoreshejwe. Nubwo YD150RH30 yujuje imipaka yo gufata ubushuhe bwa ASTM D7032—kandi ikora neza mu mirimo yo mu ngo no mu bucuruzi bworoheje—icyitegererezo cya YD140RH23 gitanga inyungu ifatika mu bidukikije byo mu mazi. Igishishwa cya polymeri gifata amazi ku buso bwa YD140RH23 gitera imbogamizi ifatika igabanya cyane kwinjira kw’amazi mu gice cy’imbere cy’imbaho, bigatuma amazi agabanuka, ubunini buke bugabanuka, kandi uburebure bugakomeza kwiyongera mu gihe cyo gushyiraho.

Ubudahangarwa bw'imiti ni ikintu cy'inyongera ku bikoresho bipima imiterere y'ibice byo mu mazi. Amazi arimo chlorine, amazi y'umunyu mu nkombe, n'ibikoresho byo gusukura bikoreshwa mu kubungabunga ibice byo mu mazi bishobora kwangiza ubuso bwa polymer uko igihe kigenda gihita. Ydwpc ikora ibice byayo byo mu mazi bifite imiti irwanya shimi ihura n'ibiteganijwe mu gihe kirekire biri muri ASTM D7032. Ku mishinga yo mu turere two ku nkombe cyangwa mu nkombe ikoresha chlorine y'amazi y'umunyu, YD140RH23 ivanywemo ni yo isabwa, kuko ubuso bwayo bufunze burwanya ikorwa rya kristu y'umunyu n'injira rya chlorine. Ibi bihuye n'amabwiriza ava muri Gahunda ya CDC yo koga mu buryo bw'ubuzima ku kubungabunga ibikorwaremezo by’ibidendezi by’amazi birambye kandi birangwa n’umutekano.

6. Ubudahangarwa bwo Kunyerera: Isuzuma ry'Ubushyuhe bw'Ingano ku Mapantaro yo mu Kidendezi cy'Imvura

Ubudahangarwa bwo kureremba bushobora kuba ari bwo buryo bw'ingenzi bwo kwirinda ku gice cy'ubucuruzi cya pisine, kandi ni kimwe mu bintu bya mbere abagenzuzi bagenzura iyo basuzuma ibicuruzwa bya WPC. Nubwo ASTM D7032 ivuga ku kudahangarwa no kureremba nk'igice cy'ibipimo byayo by'imikorere, abagenzuzi benshi banagaragaza andi mahame nka ASTM C1028 n'amabwiriza agenga uburyo bwo kugera ku bantu bafite ubumuga (ADAAG), agaragaza ko ntarengwa umubare ntarengwa w'agaciro k'ubushyuhe ku nzira zigendwa. ADAAG isaba ko umubare ntarengwa w'ubushyuhe ku buso buringaniye wa 0.6 na 0.8 ku nzira zijyamo, kandi aya gaciro akoreshwa cyane ku buso bw'ubucuruzi bw'ibigega bya pisine hatitawe ku bubasha bw'aho hantu.

Ubuso bwa WPC butuma budashobora kunyerera binyuze mu miterere y'ubuso—igishushanyo cyashushanyijwe cyangwa cyakozwe mu gice cy'ubuso cy'urubaho mu gihe cyo gukora. YD150RH30 na YD140RH23 byombi biva kuri Ydwpc bifite ubuso bw'ibiti bukozwe mu buryo bugamije kugumana imbaraga iyo butose. YD140RH23 yakuwemo ifite inyungu y'inyongera: urwego rwayo rw'umupfundikizo rwakozwe n'inyongera zirinda kunyerera ziri muri matrix ya polymer, zitanga agaciro gahoraho k'ubushyuhe ndetse na nyuma y'imyaka myinshi y'urugendo rw'amaguru n'imiti ishobora koroshya imiterere y'ubuso bw'imiterere ya kera. Ku gice cy'ubuso cya pisine gifite ubuso bwa metero kare 1,000, ubu buryo burambye ni ingenzi cyane, kuko igice cy'ubuso gitsinda ikizamini cyo kunyerera iyo gishya ariko kigaserera nyuma y'impeshyi ebyiri gikoreshwa gitera ikibazo gihoraho cy'umutekano n'ubwishingizi.

Abapima ibikoresho bagomba gusaba amakuru y’ikizamini cya COF ku nganda za WPC zirimo gusuzuma. Ydwpc itanga aya makuru nk'igice cy'ikizamini cyayo gisanzwe cya D7032, cyageragejwe muri laboratwari zigenga kugira ngo hakurweho amakimbirane ayo ari yo yose y’inyungu. Porogaramu y’ikizamini ikubiyemo gupima imbaraga zisabwa kugira ngo hatangwe uburyo bwo kunyerera kw'ikirenge cy’ikizamini cya rubber gisanzwe ku buso bw’ikizamini butose, kandi ibisubizo bigaragazwa nk'uburyo butagira ingano. Imiterere ya Ydwpc yo mu cyiciro cya pisine ihora igera ku gaciro ka COF gatose karenze urugero rwa ADAAG, biha abapima ibikoresho icyizere cy'uko ubuso bw'ikizamini buzakomeza kuba bwiza mu bihe bibi cyane by'ubutose bishobora guterwa n'ibidukikije bya pisine y'ubucuruzi. Aya makuru ashyigikira inshingano z'umupima kandi yoroshya inzira yo kwemeza hamwe n'abakozi b'inyubako n'abashinzwe ubwishingizi.

7. Gukomera kwa UV no Kugumana Ibara mu gihe cyose cy'akazi

Ubusanzwe, amadirishya yo mu bidendezi by'ubucuruzi ashyirwa ahantu hagaragara cyane kandi hari imirasire y'izuba myinshi. Imirasire ya UV ituruka ku zuba ni yo mpamvu nyamukuru ituma amabara ashira, gushonga kw'isukari, no kwangirika kwa polymer mu bikoresho bya WPC. ASTM D7032 isuzuma uburyo UV idahinduka binyuze mu bizamini by'imihindagurikire y'ikirere, ibipimo byerekana ko UV yihuta cyane hakoreshejwe igikoresho cya xenon-arc cyangwa fluorescent UV, biganisha ku myaka yo kwibasirwa n'izuba mu gihe gito. Ihame ripima impinduka z'ibara (delta E) no kwangirika kw'ubuso nyuma y'igihe cyagenwe cyo kwibasirwa, kandi ibipimo bikoresha ibi bipimo kugira ngo bihanure ko isura izagumana igihe kirekire.

Ku gice cy’ubucuruzi cya pisine, guhagarara kw’amabara bigira ingaruka ku bwiza no ku mikorere. Mu buryo bwiza, amahoteli n’amahoteli ashora imari mu mvugo yihariye y’igishushanyo, kandi igice cy’imbere kidahinduka mu myaka ibiri cyangwa itatu cyangiza imiterere y’aho hantu. Mu buryo bwiza, kwangirika kwa UV bigabanya imbaraga za polymer ku buso bw’ikibaho, bigagabanya imbaraga zo kuzunguruka no kudacika intege uko igihe kigenda gihita—bikangiza imiterere nyirizina yagenzuwe na D7032 ubwo yaguraga. Niyo mpamvu isuzuma ry’uguhagarara kwa UV atari agasanduku ko kwisiga gusa ahubwo ari ikintu gipimo cyo gukomera kw’imiterere.

Ydwpc ikoresha paki zo guhagarara neza kwa UV mu buryo bworoshye haba mu miterere yayo ya kera ndetse no mu miterere ya co-extrusion. Profaili ya kera ya YD150RH30 ikoresha uruvange rwa vitesi za amine zidafite aho zihuriye (HALS) na vitesi za UV zikwirakwizwa mu buryo bwose, bitanga uburinzi bw'ibanze bwa UV. Modeli ya co-extrusion ya YD140RH23 ikomeza ibi: urwego rw'umupfundikizo wa polymer rukozwe mu buryo bwa "concentrated UV stabiliser" burinda ibikoresho by'ibanze, bigatuma UV ikomeza kwikuba kabiri ugereranyije na vitesi za kera. Ubu buryo bwa "cap-layer" bumeze nk'uburyo ikoranabuhanga ryo gukata amadirishya avanze Yateye imbere mu nganda zose, aho ikoreshwa rya "co-extrusion" rigaragaza urwego rugezweho rw'ubu. Ku bashaka gutumiza "piscine decking" ifite ubuso bwa metero kare 1,000, YD140RH23 ni yo mahitamo meza iyo ibara rigumana mu gihe cy'imyaka 15 kugeza kuri 25 ari ngombwa mu mushinga, mu gihe YD150RH30 itanga ubundi buryo buhendutse aho ibara rigabanuka mu rugero runaka cyangwa aho "pascine" ifite igicucu gito.

8. Co-Extrusion vs. Classic WPC: Kugereranya uruhande ku rundi kw'inyuma y'inyuma y'inyuma

Iyo igikoresho gipima ahantu hanini ho gupima pisine y’ubucuruzi gifite ubuso bwa metero kare 1.000 kikagera ku bicuruzwa bibiri byatoranyijwe n’uruganda rumwe, akenshi amahitamo ashingiye ku bwubatsi bwa kera ugereranyije n’ubw’inganda zikoresha uburyo bwo gupima. Ydwpc itanga byombi muri kataloge yayo: YD150RH30 ihagarariye inyubako ya kera ya WPC, mu gihe YD140RH23 ari uburyo bwo gupima ahantu hanini. Gusobanukirwa itandukaniro mu nganda, imikorere, n’ikiguzi ni ingenzi kugira ngo hafatwe icyemezo gikwiye ku bijyanye n’inyubako ya pisine.

Ibaraza rya kera rya WPC nka YD150RH30 rikorwa hakoreshejwe uburyo bwo gusohora ibintu rimwe aho fibre y'ibiti, resin ya polymer, ibintu bihuza, ibintu bitera irangi, n'ibikomeza bivangwa kandi bigasohorwa binyuze mu gice kimwe. Urubaho ruvuyemo rufite igice kimwe gifite imiterere imwe y'ibikoresho kuva hejuru kugeza hasi. Iyi nyubako imaze imyaka makumyabiri ikoreshwa mu bucuruzi kandi iracyari amahitamo yizewe kandi ahendutse ku bikorwa byinshi. YD150RH30 yujuje ibisabwa byose bya ASTM D7032, harimo n'umubare w'imbaraga za 28 MPa, kandi uburebure bwayo bwa mm 150 na mm 30 butanga ubushobozi bw'imiterere bukenewe ku gice gisanzwe cy'ibaraza ry'ipamba ry'ubucuruzi.

Icupa rya "co-extrusion deck" nka YD140RH23 ryongeraho intambwe ya kabiri yo gusohora: igishishwa cya polymer kirinda (urwego rw'umupfundikizo) gifatanye n'inkingi ya WPC mu gihe cyo gusohora "co-extrusion". Uru rwego rw'umupfundikizo rwakozwe kugira ngo rwongere ubushobozi bwo kurwanya imirasire ya UV, kudapfa kw'amazi, kudacika intege, no kudahinduka kw'amabara. Ingaruka ni ikibaho girusha WPC ya kera hafi ya yose ku gipimo cyo kuramba, nubwo ku giciro kiri hejuru kuri metero kare. Ku macupa ya pisine y'ubucuruzi, inyungu yo gusohora "co-extrusion" igaragara cyane mu gufata ubushuhe, kugumana ibara rya UV, no kudacika intege igihe kirekire. Imbonerahamwe iri hepfo igaragaza itandukaniro ry'ingenzi:

Ku muntu ugena ibintu byagenwe ukoresheje metero kare 1,000, uburyo bwo gufata ibyemezo bworoshye: niba urwego rw'amazi ruri ahantu hashyushye cyane, hari ubushuhe bwinshi, kandi hari amazi y'umunyu cyangwa imiti ikoreshwa cyane, YD140RH23 co-extrusion profile ni yo mahitamo meza cyane. Niba umushinga ufite ingengo y'imari nke, urwego rufite igicucu gito, cyangwa ikigo gikoresha amazi yoroshye, YD150RH30 classic profile itanga ASTM D7032 yujuje ibisabwa ku giciro gito. Itsinda rya Ydwpc ryohereza ibicuruzwa mu mahanga rishobora gutanga ingero z'ibibaho byombi kugira ngo bisuzumwe, hamwe n'ibyemezo byuzuye by'ibizamini bya D7032 n'amabwiriza yo gushyiraho, bituma umuhanga mu byagenwe afata icyemezo gisobanutse neza mbere yo kwemeza gutumiza ibintu byinshi.
