Gupfuka WPC vs Gupfuka Inzu gakondo: Isesengura ry'Ikiguzi n'Inyungu ku Bubatsi bw'Ubucuruzi

Igiciro nyacyo cyo gupfunyika ibiti ntawe uvuga ku cyiciro cy'ipiganwa

Maze imyaka icumi ishize mfasha abatumiza ibikoresho by'ubwubatsi mu Burayi, Amerika ya Ruguru, no muri Aziya y'Amajyepfo. Wpc Decking, uruzitiro, no gupfunyika biva mu nganda z’Abashinwa. Ibiganiro hafi ya byose bitangira mu buryo bumwe: umwubatsi yagennye gupfunyika ibiti (ubusanzwe ni Western Red Cedar, Larch, cyangwa thermowood pine), rwiyemezamirimo agatanga ibiciro ku bikoresho no kubishyiramo, maze umushinga ugatera imbere ukoresheje igisubizo gisa n’aho ari cyiza kandi gihendutse.

Icyo ibiciro bya mbere bitajya bikubiyemo ni ikiguzi cyo kubungabunga gikomeza kwiyongera buri mwaka nyuma yo gushyirwaho. Gupfuka imbaho ​​bisaba gusiga irangi cyangwa amavuta buri myaka 2-5 bitewe n'ubwoko, uburyo ikwirakwira, n'ubwoko bwayo. Mu majyaruguru y'Uburayi, aho imvura, ubukonje, n'imiraba y'izuba biba bikomeye, inyubako y'ubucuruzi ifite metero kare 500 zo gupfuka imbaho ​​izakoresha $3,000-6,000 kuri buri gihe cyo kubungabunga inyubako, imirimo n'ibikoresho - buri myaka 3, mu gihe cyose inyubako izaba ikiriho.

Iyo neretse ba rwiyemezamirimo na ba nyir'inyubako igereranya ry'ibiciro by'imyaka 20 hagati y'ibumba risanzwe ry'ibiti n'ibumba rya WPC co-extrusion, imibare ihora ishyigikira WPC ku rugero runini. Dore uko iryo sesengura rikora.

Udupfundikizo twa WPC Co-Extrusion ni iki kandi dukorwa dute?

WPC (ibikomoka ku giti-plastiki) ni ibikoresho byakozwe mu buryo bwa tekiniki bikozwe mu ruvange rw'imigozi y'ibiti (ubusanzwe 50-60%), polymeri ya thermoplastic (HDPE cyangwa PP, 30-35%), hamwe n'inyongeramusaruro (5-15%) zirimo ibintu bitera imbaraga UV stabilizers, amarangi y'amabara, imiti ihuza ibyuma, n'imiti yica udukoko. Uruvange rurashyuha, ruvangwa, kandi rugasohoka binyuze mu kintu cyometseho kugira ngo rukore imbaho ​​zifite igice gihamye.

Gushyira hamwe mu gutunganya ibintu ni intambwe ikomeye itandukanya ibirungo bya WPC bigezweho n'ibicuruzwa bya mbere bivanze. Mu gikorwa cyo gusohora hamwe, icyuma cya kabiri gikoresha urwego rw'umupfundikizo wa polymer (ubusanzwe rufite ubugari bwa mm 0.3-0.7) hafi y'inkingi ya WPC iyo isohoka mu gice cy'ibanze. Uru rwego rw'umupfundikizo - rwakozwe mu buryo bugabanya imirasire ya UV n'amabara - rukora ubuso bufunze burinda insinga z'ibiti kwinjira mu bushyuhe no kwangirika kwa UV.

Ibisubizo ni ikibaho gipfundikiye gisa n'igiti karemano (bitewe n'imiterere y'ibinyampeke byashushanyije mu gipfundikizo) ariko gikora nk'umuti wa polymeri ukora neza cyane. Ipfundo rya WPC ryo gupfunyika hamwe na YD216H25 ikorwa ku murongo wuzuye w’imashini ikoresha ikoranabuhanga hamwe n’ubugari bw’umugozi mu gihe nyacyo kugira ngo harebwe uburinzi buhoraho kuri buri metero ingana. Dukora kandi ibicuruzwa byuzuzanya - ku mishinga ikeneye ipaki yuzuye yo hanze, Urusobe rw'uruzitiro rwa WPC isangiye ikoranabuhanga rimwe ryo gusohora hamwe n'uburyo bumwe bwo guhuza amabara.

Igereranya ry'Ibiciro by'Imyaka 20: WPC vs Igipfunyika cy'Imbaho

Kubera ko gupfuka WPC hamwe no kuyitunganya bidasaba gusana buri mwaka — nta gusiga irangi, nta gufunga, nta gusiga amavuta — ikiguzi cy’imyaka 20 cyo gutunga ni 35-50% munsi y’ibiti byoroshye byatunganyijwe kandi kiri munsi ya 55-65% ugereranyije n’ibiti by’igiciro cyinshi. Iyi mibare irushaho kuba ikomeye iyo ugereranyije n’ikiguzi cyo kubaka inyubako z’ubucuruzi zifite amagorofa menshi, aho uburyo bumwe bwo kubungabunga bushobora gutwara $10.000-20.000 mu bikoresho byonyine.

Igereranya ry'imikorere: Ubushuhe, UV, no kurwanya udukoko

Ku bubatsi b’ubucuruzi, ibipimo by’imikorere by’ingenzi ni ugukomera mu buryo bungana mu gihe cy’ubushuhe, kugumana amabara mu gihe cy’imirasire y’imiraba ya UV, no kudahura n’ibitero by’ibinyabuzima (udukoko n’ibihumyo).

• Uburyo bwo kwinjiza ubushuhe: Udupfundikizo tw’ibiti dufata ubushuhe buri hagati ya 12-25% iyo twuzuye, bigatera kubyimba, kugorama, no gupfunyika. Udupfundikizo twa WPC dufata ubushuhe buri munsi ya 1% bitewe n’ubushuhe - urwego rw’umupfundikizo wa polymer rufunga igice cy’imbere cy’imbaho ​​ku mazi ataziguye. Ibi bivuze ko imbaho ​​za WPC zigumana ubushobozi bwazo bwo kwihanganira imvura, urubura, n’ubushuhe mu gihe cy’imvura, urubura n’ubushuhe hatabayeho icyuho cyo kwaguka no gufunga imbaho ​​nk’uko udupfundikizo tw’imbaho ​​tubisaba.
• Ubudahangarwa bw'imirasire y'izuba: Ibiti bitarakingiwe birangirika bitewe n’imirasire ya UV — lignin iri mu mugozi w’ibiti irasenyuka, bigatuma ubuso buhinduka imvi kandi bugahinduka nk’umukara mu mezi 6-12 nyuma yo kugaragara. Nubwo bamwe mu bahanga mu by’ubwubatsi baha agaciro ubu buryo bw’ikirere busanzwe, ba nyir’inyubako z’ubucuruzi ubusanzwe ntibabiha agaciro. Ubuso bwa WPC bugumana ibara ryabwo ry’umwimerere mu gihe cy’imyaka 15-25 kuko urwego rw’umugozi rugizwe n’ibintu bitera imbaraga za UV (ubusanzwe HALS — ibintu bitera imbaraga za amine — ku kigero cya 2-4% by’umutwaro) bikurura kandi bigakuraho ingufu za UV mbere yuko bigera ku gice cy’imbere cy’umugozi w’ibiti.
• Ubudahangarwa bw'udukoko n'ibihumyo: Gupfuka imbaho ​​bibangamirwa n’inyenzi, udukoko dutobora imbaho, ndetse no kubora kw’ibihumyo - cyane cyane mu turere dushyuha kandi dukonje. Gupfuka WPC birimo imiti yica udukoko n’imiti bivanze mu gice cy’ingenzi cy’ingirabuzimafatizo mu gihe cyo gukora, bigatanga uburinzi bw’ibinyabuzima bwubatswemo nta miti ikoreshwa nyuma yo gukora.

Iyubahirizwa ry'amategeko agenga imikorere y'inkongi n'amategeko agenga inyubako

Imikorere y'inkongi ni ingenzi cyane ku bikoresho byo gupfuka ibyuma mu bucuruzi, cyane cyane mu Burayi nyuma y'ibyago byabereye ku munara wa Grenfell ndetse no gukaza amategeko agenga inyubako mu bihugu by'Ubumwe bw'u Burayi. Dore aho gupfuka ibyuma bya WPC bihagaze mu mikorere y'inkongi:

Ubusanzwe, igitambaro gisanzwe cya WPC (kidafite inyongeramusaruro zigabanya umuriro) kigera ku gipimo cya C cyangwa Class D hakurikijwe sisitemu yo mu Burayi yo gushyira mu byiciro inkongi, ihuye n'ingaruka z'inkongi nk'imbaho ​​z'ubucucike buri hagati. Ku nyubako z'ubucuruzi zikenera imbaraga z'inkongi zo mu cyiciro cya B, hari imiterere ya WPC igabanya umuriro irimo imyunyungugu (aluminium trihydrate, magnesium hydroxide) ku kigero cya 10-20%.

Igipfundikizo cyacu cya WPC co-extrusion gifite formula irinda umuriro cyageragejwe hakurikijwe EN 13501-1 Class B-s1,d0, cyujuje ibisabwa ku nyubako ziri hejuru ya metero 18 mu bihugu byinshi by’i Burayi. Inyongeramusaruro irinda umuriro ishyirwa mu gice cy’ingenzi cy’imashini mu gihe cyo kuyikora — si igitambaro cyo hejuru gishobora kwangirika uko igihe kigenda gihita. Ibi bivuze ko imikorere y’umuriro ari ikintu gisanzwe kandi nticyangirika iyo habayeho imihindagurikire y’ikirere.

Ku mishinga yo muri Amerika y'Amajyaruguru, WPC cladding igomba kubahiriza ASTM E84 (Steiner tunnel test) kugira ngo umuriro ukwirakwire no guteza imbere umwotsi. Imiterere isanzwe ya WPC ikunze kugera ku gipimo cya Class A cyangwa Class I (flame spread index 0-25, smoke developed index 0-450) iyo igeragejwe kuri ASTM E84.

Uburyo bwo Gushyiramo Imashini mu Bikorwa: Uburyo WPC Igabanya Ikiguzi cy'Abakozi ku Gikoresho

Uretse imikorere y'ibikoresho, gupfunyika kwa WPC hamwe no gupfunyika bitanga inyungu nyinshi zo gushyiraho ibintu bifasha mu kuzigama amafaranga y'abakozi ku mishinga y'ubucuruzi:

• Sisitemu y'amashusho ahishe. Igipfunyika cyacu cya YD216H25 gikoresha agapira k'icyuma kidapfunyika kihishe kijya mu muyoboro w'imbere w'ikibaho. Nta gupfunyika ku maso, nta n'ibifunga bigaragara, kandi buri kibaho gifunga mu kindi gifite intera ihoraho. Ubu buryo bwihuta 30-40% mu gushyiramo kurusha igipfunyika cy'imbaho ​​gikozwe mu maso kuko uwagishyizeho adakeneye gutobora mbere, gusimbuza, cyangwa guhuza inzara ku giti cye.
• Nta mpamvu yo kuvurwa mbere y'uko uvurwa. Imbaho ​​zo gupfuka imbaho ​​akenshi zisaba gupfukwa, gupfundika amapfundo, no gusiga irangi mbere yo gushyirwaho. Imbaho ​​za WPC ziba ziteguye gushyirwaho uhereye ku gipfunyika - zikata uburebure, zigakatwa, hanyuma zikimurwa ku kindi kibaho.
• Ubushobozi bwo kwihanganira ibintu mu buryo buhoraho. Imbuga za WPC zikozwe mu ruganda zigumana ubushobozi bwo kwihanganira uburebure bwa ± 0.5mm mu gihe cyose cy'umusaruro. Imbuga z'ibiti karemano zishobora gutandukana hagati y'ubugari na 2-5mm hagati y'imbaho, bigasaba gutondeka no guhitamo aho zigomba kuba ziherereye. Imbuga za WPC zihamye bivuze ko zigomba gushyirwa hamwe kandi ko zigomba gushyirwaho vuba kandi neza.
• Uburemere bworoshye. Ibyuma byo gupfunyika bya WPC bipima ibiro bigera kuri 2.0-2.5 kuri metero imwe (ku byubakwa bifite ubugari bwa mm 216), ugereranije na kg 3.0-4.5 ku byubakwa bifite ibiti bingana. Uku kugabanya uburemere bigabanya umunaniro w'abashyiraho, byoroshya ibikoresho byo gupfunyika, kandi bigabanya umutwaro w'inyubako ku gipfunyika cy'inyubako.

Ibitekerezo Bisanzwe Bitari byo Ku bijyanye no Gupfuka WPC

Mu bunararibonye bwanjye bwo gufasha abacuruza ibiti kuva ku giti bakajya kuri WPC, njya mpura n'ibitekerezo bimwe bitari byo kenshi. Gukemura ibi bibazo mbere y'igihe birinda amakosa ahenze:

Igitekerezo cya 1: "WPC isa n'iy'impimbano." WPC yo mu gisekuru cya mbere yari ifite imiterere isa kandi isubiramo. Ikoranabuhanga rigezweho ritanga imiterere y’ibiti n’ibinyampeke bifite ibara ryimbitse rifite ibara ritandukanye. Ku ntera yo kureba ya metero 3-5 (isanzwe ku nkuta), ndetse n’abubatsi b’inararibonye ntibashobora gutandukanya WPC nziza n’ibiti batabikozeho. Umusaruro wacu ukoresha imigozi ya CNC ifite imiterere y’ibinyampeke bivuye ku biti nyabyo, bigatuma habaho itandukaniro rya mm 0.5-0.8 z’ubujyakuzimu.

Igitekerezo cya 2: "WPC iremereye cyane ku buryo itagomba guhindurwa." Ku gipimo cya 2.0-2.5 kg kuri metero imwe ku kibaho gifite ubugari bwa mm 216, WPC ni yoroshye kurusha izindi mbaho ​​zikozwe mu giti. Ikibazo gikunze guterwa no kwitiranya imbaho ​​zikozwe mu nyubako. Imbaho ​​zikozwe mu nyubako ntizishingiye ku nyubako kandi zikorana n'inkingi zisanzwe z'ibiti.

Igitekerezo cya 3: "WPC ntishobora kwihanganira imiyoboro." Nubwo WPC idashobora gukonja nk'ibiti bito, gukora ubushyuhe bituma habaho imiterere yoroheje (radius irenga metero 3-4). Ku miterere mito, imiterere ya WPC yoroshye ifite ibice bito ifata imirasire kugeza kuri metero 2 iyo ishyushye kugeza kuri dogere selisiyusi 80-100.

Kubera ko izi myumvire idahwitse ituma abahanga mu by'ubwubatsi banga WPC nta suzuma rikwiye, ndakugira inama yo gutanga ingero zifatika ku bibaho byo gushushanya aho hantu. Iyo umwubatsi amaze kubona icyitegererezo cya WPC cya metero 3x3 hamwe n'ibipimo by'imbaho, kugereranya hafi ya buri gihe bituma WPC ikoreshwa mu bucuruzi.

Ibitekerezo ku kubungabunga ibidukikije n'ibidukikije

Ku bubatsi b'ubucuruzi bashaka ibyangombwa by'ubwubatsi budakoresha ikoranabuhanga (LEED, BREEAM, cyangwa DGNB), WPC cladding igira uruhare mu byiciro byinshi by'inguzanyo:

• Ibikubiye mu bubiko byasubiwemo. Ibibaho bya WPC birimo 50-60% by'imigozi y'ibiti (ikomoka ku myanda y'ibiti byasubiwemo n'ibikomoka ku nganda) na 30-35% bya HDPE yasubiwemo (pulasitiki yasubiwemo nyuma yo kugurwa). Iri janisha ry'ibikubiye mu bubiko ryasubiwemo ryujuje ibisabwa kugira ngo rihabwe LEED MR Credit: Gutangaza no Guteza imbere Ibicuruzwa by'Ubwubatsi — Gushakisha Ibikoresho Bishamikiyeho.
• Nta giti cy'ibiti gishyuha. Gukoresha WPC aho gukoresha ibiti binini byo mu turere dushyuha (Ipe, Cumaru, Balau) bikuraho itemwa ry'amashyamba n'ingaruka z'urusobe rw'ibinyabuzima bifitanye isano no gusarura ibiti byo mu turere dushyuha. Ibi bihuye n'ibyatanzwe na BREEAM MAT 03 (Responsible Sourcing).
• Uburyo bwo kongera gukoresha ibintu mu mpera z'ubuzima.Igipfundikizo cya WPC gishobora gusya no kongera gukurwamo mu gishya Igicuruzwa cya Wpcs mu mpera z'ubuzima — bitandukanye n'ibiti bitwikiriwe n'ibintu bibungabunga ibidukikije, bigomba gutabwa nk'imyanda iteje akaga mu turere twinshi.

Kubera ko igitambaro cya WPC gikozwe mu migezi y'imyanda (imigozi y'ibiti ikoreshwa mu buryo bushya na pulasitiki ikoreshwa mu buryo bushya), gikemura ibisabwa mu bukungu bw'uruziga bikomeje gukurikizwa mu bipimo by'amasoko ya leta y'i Burayi.
