Ukuguguleka komhlabathi ogwini lolwandle, osebeni lomfula kanye nasezindaweni ezisogwini lolwandle kusalokhu kuyindaba eqhubekayo kubakhi bomphakathi emhlabeni jikelele. Izinto eziningi zokufaka inqwaba yempahla zendabuko ziyalwa namanzi anosawoti, umswakama kanye nokuchayeka esimweni sezulu isikhathi eside. Namuhla,inqwaba yeshidi lepulasitikiimikhiqizo, kufaka phakathi inqwaba yeshidi le-pvc kanyeudonga lwenqwaba yeshidi le-vinylizinhlangano, zithola amandla omhlaba wangempela njengendlela ewusizo nengadingi ukunakekelwa okwengeziwe yomsebenzi wokuvikela ogwini. Kumaqembu ephrojekthi afuna ukunqwabelanisa amaphepha epulasitiki noma ukunqwabelanisa amaphepha e-Vinyl Sheet For Sale, ukuqonda amandla ezinto ezibonakalayo kusiza ekwenzeni izinqumo ezingcono zokuthenga ingqalasizinda ehlala njalo yasemanzini.

Kwenziwe nge-polyvinyl chloride eguquliwe,inqwaba yeshidi le-pvckuletha izinzuzo zokusebenza ezihlukile ezihlukanisa insimbi, ukhuni kanye nezinketho zekhonkrithi. Amandla ayo avelele okulwa nokugqwala avelele kakhulu: ukuxhumana njalo namanzi agcwele usawoti, inhlabathi emanzi kanye nokukhanya kwelanga kwe-ultraviolet ngeke kubangele ukugqwala noma ukubola, okunciphisa kakhulu izindleko zokulungisa zesikhathi esizayo.

Udonga lwenqwaba yeshidi le-vinyl olwakhiwe kahle lwakha amalunga aqinile axhumene. Lo mklamo uletha ukuhlanganiswa kwenhlabathi okuqinile, ukusebenza okungangeni amanzi kanye nomthamo wokukhipha amanzi ophumelelayo, ohlanganisa izidingo zobunjiniyela eziyinhloko zokuzinzisa ugu lolwandle. Ngaphandle kokusebenza komshini, lolu hlobo lwenqwaba yeshidi lepulasitiki luphinde lube nezimfanelo ezinobungani nemvelo. Ngeke lukhiphe izinto eziyingozi emanzini noma enhlabathini ezungezile, okwenza lufanelekele izinhlelo zokuvuselela ulwandle oluzwela imvelo.

Impendulo yasensimini ikhombisa ukuthi ukufakwa kuhamba ngokushesha. Uma kuqhathaniswa nokufakwa kwezinsimbi ezisindayo, la maphaneli anesisindo esincane kakhulu. Ukuphathwa kwezokuthutha kanye nendawo kuba lula, kunciphisa imijikelezo yokwakha yokuqinisa usebe lomfula, izindawo zokubopha izindonga kanye nezithiyo zokuvimbela izikhukhula. Kungakhathaliseki ukuthi amakhasimende athola inqwaba yepulasitiki ethengiswayo noma afunaUkufakwa Kweshidi Le-Vinyl Kuthengiswa, bathola uhlelo olwakhelwe ukubekezelela amashumi eminyaka ezimo zangaphandle ezinzima.

I-ZZ Group yasungulwa ekuqaleni kwawo-1980 futhi inendlunkulu yayo eSifundeni saseYangpu, eShanghai. Njengeqembu elikhulu lebhizinisi elibanzi, ububanzi bebhizinisi layo buhlanganisa ukuhweba ngensimbi, ukucutshungulwa nokusatshalaliswa kwensimbi, ukuhlinzekwa kwezinto zokusetshenziswa, ukuthuthukiswa kwezindlu kanye nokutshalwa kwezimali. Njengoba imali ebhalisiwe ifinyelele ku-RMB eyizigidi ezingu-200, leli qembu lithole udumo embonini okuhlanganisa ukuhweba ngensimbi kazwelonke kanye nokuthutha “ibhizinisi elikhulu lokholo oluhle” kanye “namabhizinisi azimele ayi-100 aphezulu eShanghai”. Lisebenzisa izinsiza eziningi zokunikezela, leli qembu lisekela amakhasimende omhlaba wonke adinga inqwaba yepulasitiki efanelekile, inqwaba yephepha le-pvc kanye nezixazululo zodonga zenqwaba yephepha le-vinyl eziphelele zezabelo zokuvikela ogwini.

Amaphrojekthi okuvikela ugwini adinga izinto zokwakha ezilinganisela ukuqina, ukulawulwa kwezindleko kanye nokuhambisana kwemvelo. Inqwaba yeshidi lepulasitiki, okuyinqwaba yeshidi le-pvc kanye nodonga lwenqwaba yeshidi le-vinyl oluhlanganisiwe, hlola la mabhokisi ngempumelelo. Uma uphequlula ukunqwabelanisa amaphepha epulasitiki athengiswayo noma ukunqwabelanisa amaphepha e-vinyl athengiswayo, abanikazi bephrojekthi kufanele babeke phambili abahlinzeki abaqinisekisiwe ngekhwalithi. Ukuze kuqiniswe usebe lomfula, ukwakhiwa kwezindonga zolwandle kanye nemisebenzi yokulwa nokuguguleka komhlabathi, izinhlelo zesimanje ze-vinyl kanye ne-PVC zimelela inketho yezinto ezibonakalayo zokucabanga kusengaphambili emkhakheni wobunjiniyela bomphakathi wanamuhla.
