1. Amaphrofayili e-PVC
Amaphrofayili namaphrofayili e-PVC yizindawo ezinkulu kakhulu zokusetshenziswa kwe-PVC eShayina, abiza cishe u-25% wesamba sokusetshenziswa kwe-PVC. Asetshenziswa kakhulu ekwenzeni iminyango namafasitela nezinto zokonga amandla, futhi umthamo wokusetshenziswa kwawo usakhula kakhulu ezweni lonke. Emazweni athuthukile, isabelo semakethe seminyango namafasitela epulasitiki naso sihamba phambili, njengo-50% eJalimane, u-56% eFrance, kanye no-45% e-United States.
2. Ipayipi le-PVC
Phakathi kwemikhiqizo eminingi ye-PVC, amapayipi e-PVC ayinsimu yesibili ngobukhulu yokusetshenziswa, ebiza cishe u-20% wokusetshenziswa kwawo. E-China, amapayipi e-PVC athuthukiswa ngaphambi kwamapayipi e-PE namapayipi e-PP, anezinhlobo eziningi, ukusebenza okuhle kakhulu kanye nobubanzi bokusetshenziswa, ethatha isikhundla esibalulekile emakethe.
3. Ifilimu ye-PVC
Ukusetshenziswa kwe-PVC emkhakheni wefilimu ye-PVC kusendaweni yesithathu, kubalelwa cishe ku-10%. Ngemva kokuxuba nokwenza ipulasitiki ye-PVC ngezithasiselo, sebenzisa ikhalenda enemigqa emithathu noma emine ukwenza ifilimu ecacile noma enemibala enobukhulu obuthile, bese uyicubungula ngale ndlela ukuze ibe ifilimu enemigqa. Izikhwama zokupakisha, amajazi emvula, izindwangu zetafula, amakhethini, amathoyizi afuthwayo, njll. nazo zingacutshungulwa ngokusika nokuvala ukushisa. Ifilimu ebanzi ecacile ingasetshenziswa ekushiseni, ekushiseni kwepulasitiki kanye nefilimu yepulasitiki. Ifilimu enwetshiwe kabili ingasetshenziswa ekupakisheni okuncishisiwe ngenxa yezici zayo zokuncipha kokushisa.
4. Izinto eziqinile ze-PVC kanye nebhodi
Faka iziqinisi, izinto zokugcoba kanye nezigcwalisi ku-PVC, bese ngemva kokuxuba, sebenzisa i-extruder ukukhipha amapayipi aqinile, amapayipi anomumo okhethekile, kanye namapayipi ahlanganisiwe anobubanzi obuhlukahlukene, angasetshenziswa njengamapayipi okuhambisa indle, amapayipi amanzi okuphuza, izimbobo zocingo noma izibambo zezitebhisi. Amashidi ahlanganisiwe afakwa phezulu futhi acindezelwe ngokushisa ukuze kwenziwe amapuleti aqinile anobukhulu obuhlukahlukene. Amapuleti angasikwa abe yizimo ezifiselekayo, bese ehlanganiswa ngomoya oshisayo kusetshenziswa izinduku zokushisela ze-PVC ukuze kwakhiwe amathangi okugcina ahlukahlukene angamelani namakhemikhali, amapayipi omoya kanye nezitsha.
5. Imikhiqizo ethambile ejwayelekile ye-PVC
Ama-extruder angasetshenziswa ukukhipha amapayipi, izintambo, izintambo, njll.; imishini yokubumba umjovo ingasetshenziswa ukufanisa isikhunta esahlukahlukene ukwenza amasandali epulasitiki, amasoli, amaslippers, amathoyizi, izingxenye zezimoto, njll.
6. Izinto zokupakisha ze-PVC
Imikhiqizo ye-PVC isetshenziswa kakhulu ezitsheni ezahlukahlukene, amafilimu kanye namashidi aqinile okupakisha. Izitsha ze-PVC zisetshenziswa kakhulu ekukhiqizeni amanzi amaminerali, iziphuzo, namabhodlela ezimonyo, futhi zisetshenziswa nasekupakisheni amafutha acwengekile. Ifilimu ye-PVC ingasetshenziswa ukuhlanganisa nezinye i-polymers ukukhiqiza ama-laminate ashibhile, kanye nemikhiqizo esobala enezakhiwo ezinhle zokuvimbela. Ifilimu ye-PVC isetshenziswa futhi ekugoqweni okunwebekayo noma okuncishisiwe komatrasi, indwangu, amathoyizi kanye nezimpahla zezimboni.
7. Uphahla lwe-PVC kanye nophahla
I-PVC siding isetshenziswa kakhulu ukufaka esikhundleni se-aluminium siding. Ngaphandle kwengxenye ye-polyvinyl chloride resin, ezinye izingxenye zamathayela ephansi e-polyvinyl chloride ziyizinto eziphinde zasetshenziswa, izinamathiseli, izigcwalisi kanye nezinye izingxenye, ezisetshenziswa kakhulu emhlabathini wezakhiwo zesikhumulo sezindiza kanye nomhlabathi oqinile kwezinye izindawo.
8. Izimpahla zabathengi ze-polyvinyl chloride
Isikhwama semithwalo siwumkhiqizo wendabuko owenziwe nge-polyvinyl chloride. I-polyvinyl chloride isetshenziselwa ukwenza izikhumba zokulingisa ezahlukahlukene zezikhwama zemithwalo nemikhiqizo yezemidlalo efana ne-basketball, ibhola lezinyawo kanye ne-rugby. Ingasetshenziswa futhi ukwenza amabhande eyunifomu kanye nemishini ekhethekile yokuzivikela. Izindwangu ze-polyvinyl chloride zezingubo ngokuvamile ziyizindwangu ezimunca amanzi (akudingeki ukugqoka), njengezingubo zemvula, amabhulukwe ezingane, amajakethi esikhumba okulingisa kanye namabhuzu emvula ahlukahlukene. I-PVC isetshenziswa emikhiqizweni eminingi yezemidlalo nokuzijabulisa, njengezinto zokudlala, amarekhodi kanye nemikhiqizo yezemidlalo. Amathoyizi e-PVC kanye nemikhiqizo yezemidlalo inesilinganiso esikhulu sokukhula, futhi inezinzuzo ngenxa yezindleko zayo eziphansi zokukhiqiza kanye nokubumba okulula.
9. Imikhiqizo embozwe nge-PVC
Isikhumba sokwenziwa esine-backback senziwa ngokufaka i-PVC paste endwangwini noma ephepheni, bese siyifaka ipulasitiki ngaphezu kuka-100°C. Singenziwa nangokugingqa i-PVC kanye nezithasiselo zibe yifilimu kuqala, bese sicindezelwa nge-substrate. Isikhumba sokwenziwa esingena-backback sihlanganiswa ngqo sibe yishidi elithambile elinobukhulu obuthile yi-calender, bese sicindezelwa ngephethini. Isikhumba sokwenziwa singasetshenziswa ukwenza amasudikesi, izikhwama, izembozo zezincwadi, amasofa kanye nama-cushion ezimoto, kanye nesikhumba saphansi, esisetshenziswa njengezinto zokwakha phansi zezakhiwo.
10. Imikhiqizo ye-foam ye-PVC
Uma i-PVC ethambile ixovwa, kufakwa inani elifanele le-ejenti yokwenza igwebu ukuze kwakhiwe ishidi, elifakwa igwebu bese lenziwa ipulasitiki yegwebu, elingasetshenziswa njengezicathulo zegwebu, izimbadada, ama-insoles, kanye nezinto zokupakisha ezivikela ukushaqeka. Lingasetshenziswa futhi ukwakha amashidi e-PVC aqinile anegwebu eliphansi kanye nezinto ezifakwe iphrofayili ngokusekelwe kuma-extruder, angasetshenziswa esikhundleni sokhuni. Luhlobo olusha lwezinto zokwakha.
11. Ishidi elibonakalayo le-PVC
Faka i-impact modifier kanye ne-organotin stabilizer ku-PVC, bese uba yishidi elibonakalayo ngemva kokuxuba, ukwenza ipulasitiki kanye nokufaka ikhalenda. Ingenziwa ibe yizitsha ezikhanyayo ezinezindonga ezincane noma isetshenziswe ekupakisheni ama-blister nge-thermoforming. Iyinto enhle kakhulu yokupakisha kanye nezinto zokuhlobisa.
12. Okunye
Iminyango namafasitela ahlanganiswe ngezinto eziqinile. Kwamanye amazwe, kugcwele imakethe yeminyango namafasitela kanye neminyango namafasitela okhuni, amafasitela e-aluminium, njll.; izinto zokhuni mbumbulu, izinto zokwakha ezithatha indawo yensimbi (enyakatho, ogwini lolwandle); izitsha ezingenalutho.
