Ithimba lethu lobunjiniyela bokuthengisa liqondisa wonke umthengi esinqumweni se-WPC vs HDPE ngaphambi kokuba azibophezele ku-spec, ngoba ukukhetha okungalungile kwi-pool deck noma izinhlelo zokusebenza zasemanzini kubonakala zingakapheli izinyanga ezingu-12-24 zisebenza. Sakhe izinqubo zethu zokuhlola ze-QA ezizungeze izindlela zokwehluleka esizibonile ensimini, futhi izinqubo ziphakela ngqo izincomo zezinto ezenziwe yithimba lethu.
Lokho ngempela izinto ezimbili eziyikho
I-WPC (i-wood-plastic composite) decking yenziwe nge-fiber yokhuni noma ufulawa wokhuni kuhlanganiswe nama-polymer epulasitiki (ngokuvamile i-HDPE, i-PVC, noma i-PP) kanye nezithasiselo zokuqina kwe-UV, umbala, kanye nokuxhuma. Okuqukethwe kokhuni kuvame ukusuka ku-50% kuya ku-70% ngesisindo, kanti okunye kuyi-polymer kanye nezithasiselo. I-HDPE decking yenziwe ngepulasitiki ye-polyethylene engu-100% ephezulu, ngokuvamile engenakho okuqukethwe kokhuni nhlobo - i-polymer kuphela, umbala we-pigment, kanye neziqinisi ze-UV.
Umehluko oyinhloko wokusebenza ukuthi i-HDPE yenziwe ngokuphelele futhi ayingeni manzi ngo-100% ngokwakheka kwezinto, kuyilapho i-WPC incike kungqimba lwesivalo se-polymer (ku-WPC ehlanganisiwe) noma ukwelashwa kwendawo (ku-WPC yesizukulwane sokuqala) ukuze kuvinjwe amanzi angangeni enkabeni yokhuni-yepulasitiki. Indaba yedekhi lechibi lasePhuket ngenhla iwukwehluleka kwe-WPC yesizukulwane sokuqala; i-WPC ehlanganisiwe iziphatha ngendlela ehlukile kakhulu ngenxa yengqimba yesivalo.
Ngaphakathi kwe-WPC, umehluko wesizukulwane sokuqala uma kuqhathaniswa nokwehlukaniswa kwe-co-extrusion ubaluleke kakhulu kunomehluko we-WPC uma kuqhathaniswa ne-HDPE wokusetshenziswa komswakama ophezulu. I-WPC yesizukulwane sokuqala inokwakheka okufanayo kokhuni-ipulasitiki kulo lonke ibhodi, ngakho-ke noma yikuphi ukuklwebheka okusikiwe noma okungaphezulu kuveza i-fiber yokhuni emanzini. I-WPC ye-co-extrusion ibopha ungqimba lwesivalo se-polymer (ngokuvamile ubukhulu obungu-0.5-1.5mm) enkabeni yokhuni-ipulasitiki ngesikhathi senqubo yokwehlukaniswa, okuvala i-fiber yokhuni ekuvezweni kwamanzi ebusweni obuphezulu kanye nasezinhlangothini zombili. Ungqimba lwesivalo luphinde lunikeze ukugqokwa kwezinkuni, umbala wombala, kanye nokuqina kwe-UV, okushiya i-core inikeze amandla esakhiwo. Yingakho umugqa wethu womkhiqizo we-YD140H23 usebenzisa i-co-extrusion kuphela - senze isicelo sokuyeka isizukulwane sokuqala. Umkhiqizo we-Wpcngo-2022 ngemuva kokubona ukwehluleka okuningi kakhulu kwensimu njenge-Phuket deck.
Ngokusebenzisa i-HDPE decking, inqubo yokukhiqiza isondele kakhulu ekukhishweni kwepulasitiki okuvamile. Ama-pellets e-HDPE ayancibilikiswa futhi aphoqwe nge-diye edala iphrofayili yebhodi, bese epholiswa bese enqunywa ubude. Umbala we-pigment uxutshwa kuma-pellets e-HDPE ngaphambi kokukhishwa, ngakho-ke umbala uhamba yonke indlela ebhodini. I-HDPE ayikwamukeli ukugqokwa kwe-wood-grain ngendlela ehlanzekile njenge-WPC, kodwa imigqa ye-HDPE decking yanamuhla ingakhiqiza ubuso obunobunjwa obufana nobunhlamvu bezinkuni ngokubonakalayo, noma ngabe bungenabo ukujula kwemibala eminingi kwe-WPC.
Ukwehluleka kwedekhi lechibi lasePhuket: yini engahambanga kahle futhi kungani
Iphrojekthi: Idekhi yechibi elingamamitha-skwele angu-800 eliseceleni kolwandle, ePhuket, eThailand.
Umthuthukisi wehhotela wayethole i-WPC decking yesizukulwane sokuqala efektri yaseShayina ngasekupheleni kuka-2023. La mabhodi afakwa eduze kwechibi elingapheli elinokuvezwa okuqhubekayo kokuchayeka kanye nomswakama wezinyanga ezintathu ngonyaka. La mabhodi aphumelele ukuhlolwa kokucwiliswa kwamanzi kwamahora angu-24 efektri kodwa awazange ahlolwe ukuthi ayakwazi yini ukumuncwa kwamanzi isikhathi eside ngokusebenzisa iziphetho ezisikiwe. Ithimba lokuthenga lalichaze "i-WPC engangeni manzi" ngaphandle kokuqinisekisa ukuthi amabhodi ayenesendlalelo sesivalo se-polymer. Babethemba ukuqeda kobuso ngaphandle kokuqonda isakhiwo esingaphansi.
NgoMashi 2024 — cishe ngemva kwezinyanga ezine ukufakwa — iziphetho ezisikiwe zamabhodi (lapho izingcezu zesaha zaveza khona umongo wokhuni-wepulasitiki) zase zimunce amanzi angu-4-5% ngesisindo. Ukuvuvukala kwakungalingani kulo lonke ububanzi bebhodi, okwabangela ukugoba okuphawulekayo esakubona ensimini. Amanye amabhodi ayenokukhula kwesikhunta okubonakalayo ezikhaleni zamalunga lapho umswakama wawuqoqana khona kodwa wawungomi. Ifektri yanikela ngokufaka amabhodi ahlulekile esikhundleni sawo kodwa yayingenalo elinye ithuba lokufaka amabhodi ndawonye elilungele ukulungiswa kabusha. Ihhotela kwadingeka livale idekhi lechibi izinyanga ezimbili ngenkathi impikiswano isebenza ngendlela eya esivumelwaneni sokushintsha.
Sisebenze nonjiniyela ohlelweni lokulungisa kabusha: i-WPC yokukhipha ngokuhlanganyela enezivalo zokugcina ezivalwe efektri, kanye nesendlalelo sokukhipha amanzi esilungisiwe kabusha ngaphansi kwedekhi ukuze kulawulwe ukugeleza kwamanzi agelezayo. Uhlelo lokulungisa kabusha luphele ngekota yesithathu ka-2024 futhi idekhi ibilokhu iqhubeka phakathi nezinkathi ezimbili zemvula kusukela ngaleso sikhathi. Indaba yePhuket iyindlela evame kakhulu yokwehluleka kwe-WPC esiyibona ezindaweni ezinomswakama ophezulu - i-WPC yesizukulwane sokuqala ngaphandle kwe-polymer cap, efakwe ezinhlelweni zokusebenza ezidinga i-WPC yokukhipha ngokuhlanganyela noma i-HDPE. Sisebenzise lolu cwaningo lwecala ezingxoxweni zethu zokuthengisa nabathengi abasha kusukela ngaleso sikhathi, ngoba lubamba izindleko zokuthola i-spec engalungile esigabeni se-RFQ.
