1. Kusekhona igebe elithile phakathi kwezinsiza zokucubungula ze-PVC zasekhaya kanye nemikhiqizo yangaphandle, futhi amanani aphansi awanayo inzuzo enkulu ekuncintisaneni emakethe.
Nakuba imikhiqizo yasekhaya inezinzuzo ezithile zendawo kanye nentengo emncintiswaneni wemakethe, sinezikhala ezithile ekusebenzeni komkhiqizo, ukuhlukahluka, ukuzinza, nezinye izici uma kuqhathaniswa nemikhiqizo yakwamanye amazwe. Lokhu kuhlobene nokubuyela emuva kwefomula yethu yomkhiqizo, ubuchwepheshe bokucubungula, ukucubungula, kanye nobuchwepheshe bangemva kokwelashwa. Amanye amabhizinisi asekhaya ayazi kahle lezi zinkinga futhi asungule ubudlelwano bokubambisana nezikhungo zocwaningo, izikhungo zocwaningo nentuthuko, futhi enze ucwaningo ngezithasiselo zepulasitiki.
2. Amafektri amancane ahlukahlukene futhi alikho ibhizinisi elihamba phambili elinesikhundla esiphelele, okuholela ekuncintisaneni okungahlelekile emakethe.
Njengamanje, kunabakhiqizi be-ACR basekhaya abangaba ngu-30, kodwa abane kuphela kubo abanomkhiqizo omkhulu (onomthamo wokufakwa minyaka yonke ongaphezu kwamathani angu-5000). Imikhiqizo yalezi zinkampani ezinkulu isungule isithombe esihle ezimakethe zasekhaya nezamazwe ngamazwe, kungakhathaliseki ukuthi umkhiqizo uhlukahlukene kangakanani kanye nekhwalithi yawo. Kodwa eminyakeni emibili edlule, ngokuchuma komkhakha wokucubungula i-PVC, ezinye izimboni ezincane ze-ACR ezinomthamo wokukhiqiza ongaphansi kwamathani ayi-1000 ziye zashesha emakethe. Ngenxa yemishini yazo yokukhiqiza elula kanye nokuqina komkhiqizo okungekuhle, la mabhizinisi angasinda kuphela ngokusebenzisa ukulahla imfucuza okungabizi kakhulu, okuholele ekuncintisaneni okukhulu kwamanani emakethe yasekhaya. Eminye imikhiqizo esezingeni eliphansi nesezingeni eliphansi yagcwala ngokushesha emakethe, iletha imiphumela emibi emabhizinisini okucubungula aphansi futhi iletha nemiphumela emibi kakhulu ekuthuthukisweni kwemboni. Kunconywa ukuthi i-Plastic Processing Association ihole ekusunguleni i-ACR Additive Industry Association, ihlanganise amazinga emboni, ilawule ukuthuthukiswa kwemboni, isuse imikhiqizo engeyiyo nephansi, futhi inciphise ukuncintisana okungahlelekile. Ngesikhathi esifanayo, amabhizinisi amakhulu kufanele andise imizamo yawo yokuthuthukisa umkhiqizo, alungise isakhiwo somkhiqizo wawo, futhi alondoloze intuthuko ehambisanayo nemikhiqizo efanayo yakwamanye amazwe.
3. Ukwenyuka kwentengo kawoyela ongahluziwe kuholele ekwenyukeni kwentengo yezinto zokusetshenziswa kanye nokwehla kwenzuzo yezinkampani.
Ngenxa yokwenyuka okuqhubekayo kwamanani kawoyela ongahluziwe emhlabeni wonke, zonke izinto zokusetshenziswa eziyinhloko zokukhiqizwa kwe-ACR, i-methyl methacrylate kanye ne-acrylic ester, zenyuke kakhulu. Kodwa-ke, amakhasimende asezingeni eliphansi asalele emuva ekukhuphukeni kwamanani omkhiqizo, okuholele ekwehleni okuvamile kwenzuzo yamabhizinisi okucubungula i-ACR. Lokhu kuholele esimweni sokulahlekelwa yimboni yonke ngo-2003 nango-2004. Njengamanje, ngenxa yokuzinza kwamanani ezinto zokusetshenziswa, imboni ibonise ukuthambekela okuhle kwenzuzo.
4. Ukuntuleka kwamakhono ochwepheshe, ucwaningo lwemboni alukwazanga ukuthuthuka ngokujulile
Ngenxa yokuthi isithasiselo se-ACR siyisengezo sezinto ze-polymer esasungulwa eShayina ngasekupheleni kweminyaka yama-1990, amayunithi aso ocwaningo nokuthuthukiswa kanye nabacwaningi bambalwa kakhulu uma kuqhathaniswa nezinye izithasiselo ezifana nama-plasticizer kanye nama-flame retardants eShayina. Ngisho noma kukhona izikhungo zocwaningo ngazinye ezisithuthukisayo, ukuntuleka kokuhlanganiswa okuhle phakathi kwabacwaningi kanye nemboni yokucubungula ipulasitiki kuholele ekungakwazini ukujulisa ucwaningo lomkhiqizo. Njengamanje, ukuthuthukiswa kwe-ACR eShayina kuncike kuphela ezikhungweni zocwaningo eziphethwe amabhizinisi ambalwa ukuhlela nokuthuthukisa. Nakuba kuye kwenziwa izimpumelelo ezithile, kukhona igebe elikhulu phakathi kwabalingani basekhaya nabangaphandle maqondana nokuxhaswa ngezimali zocwaningo, imishini yocwaningo nokuthuthukiswa, kanye nekhwalithi yocwaningo nokuthuthukiswa. Uma lesi simo singathuthukiswa ngokuyisisekelo, kuzoba yinto engaziwa ukuthi izinsiza zokucubungula zingama ziqine yini emakethe yasekhaya esikhathini esizayo.
