1. Amaphrofayili e-PVC
Amaphrofayili e-PVC namaphrofayili yizindawo ezinkulu kakhulu zokusetshenziswa kwe-PVC e-China, ezibalela cishe u-25% wengqikithi yokusetshenziswa kwe-PVC. Ngokuyinhloko zisetshenziselwa ukwenza iminyango namafasitela nezinto zokonga amandla, futhi umthamo wazo wokufaka isicelo usakhula kakhulu ezweni lonke. Emazweni athuthukile, ingxenye yemakethe yezicabha namafasitela epulasitiki nayo ihamba phambili, njengamaphesenti angama-50 eJalimane, angama-56% eFrance, nama-45% e-United States.
2. Ipayipi le-PVC
Phakathi kwemikhiqizo eminingi ye-PVC, amapayipi e-PVC ayindawo yesibili enkulu yokusetshenziswa, ebala cishe amaphesenti angu-20 okusetshenziswa kwawo. E-China, amapayipi e-PVC athuthukiswa ngaphambi kwamapayipi e-PE namapayipi e-PP, anezinhlobonhlobo eziningi, ukusebenza okuhle kakhulu kanye nobubanzi bezicelo ezibanzi, athatha isikhundla esibalulekile emakethe.
3. Ifilimu ye-PVC
Ukusetshenziswa kwe-PVC emkhakheni wefilimu ye-PVC kukleliswe endaweni yesithathu, kubalwa cishe i-10%. Ngemuva kokuxuba nokufaka ipulasitiki ye-PVC ngezithasiselo, sebenzisa i-three-roll noma i-four-roll calender ukuze wenze ifilimu esobala noma enemibala enogqinsi olucacisiwe, futhi ucubungule ifilimu ngale ndlela ukuze ibe ifilimu yekhalenda. Izikhwama zokupakisha, ama-raincoat, izindwangu zetafula, amakhethini, amathoyizi aphefumulayo, njll. Ifilimu esobala ebanzi ingasetshenziselwa i-greenhouse, i-plastic greenhouse nefilimu yepulasitiki. Ifilimu ene-biaxially stretched ingase isetshenziselwe ukugoqa ngenxa yezimpawu zayo zokushwabana ezishisayo.
4.PVC impahla eqinile kanye nebhodi
Engeza izinza, izinto zokuthambisa kanye nezigcwalisi ku-PVC, futhi ngemva kokuxuba, sebenzisa i-extruder ukuze ukhiphe amapayipi aqinile, amapayipi amise okwekhethekile, namapayipi kathayela anobubanzi obuhlukahlukene, angasetshenziswa njengamapayipi endle, amapayipi amanzi okuphuza, ama-wire casings noma ama-handrails ezitebhisi. Amashidi e-calender agxiliwe futhi acindezelwe ngokushisa ukuze enze amapuleti aqinile anobukhulu obuhlukahlukene. Amapuleti angasikwa abe yizimo ezifunwayo, bese eshiselwa ngomoya oshisayo kusetshenziswa izinduku zokushisela ze-PVC ukuze akhe amathangi okugcina ahlukene amelana namakhemikhali, imigudu yomoya neziqukathi.
5.PVC imikhiqizo ethambile evamile
Ama-extruder angasetshenziswa ukukhipha amapayipi, izintambo, izintambo, njll.; imishini yokubumba umjovo ingasetshenziselwa ukufanisa ukubunjwa okuhlukahlukene ukwenza izimbadada zepulasitiki, ama-soles, ama-slippers, amathoyizi, izingxenye zezimoto, njll.
6. Izinto zokupakisha ze-PVC
Imikhiqizo ye-PVC isetshenziswa kakhulu ezitsheni ezahlukahlukene, amafilimu namashidi aqinile wokupakisha. Iziqukathi ze-PVC zisetshenziswa kakhulu ekukhiqizeni amanzi amaminerali, iziphuzo, namabhodlela ezimonyo, futhi zisetshenziselwa ukupakishwa kwamafutha acolisisiwe. Ifilimu ye-PVC ingasetshenziselwa i-coextrusion namanye ama-polymers ukukhiqiza ama-laminates angabizi kakhulu, kanye nemikhiqizo esobala enezakhiwo ezinhle zokuvimbela. Ifilimu ye-PVC isetshenziselwa ukugoqa noma ukugoqa okugoqayo kumatilasi, indwangu, amathoyizi kanye nezimpahla zezimboni.
7. PVC siding kanye flooring
I-PVC siding isetshenziselwa ngokuyinhloko ukufaka esikhundleni se-aluminium siding. Ngaphandle kwengxenye ye-polyvinyl chloride resin, ezinye izingxenye ze-polyvinyl chloride tile floor ziyizinto ezigaywe kabusha, izinto zokunamathisela, izigcwalisi nezinye izakhi, ezisetshenziswa kakhulu phansi kwezakhiwo 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 ezihlukahlukene zezikhwama zemithwalo kanye nemikhiqizo yezemidlalo efana ne-basketball, ibhola lebhola lombhoxo. Ingase futhi isetshenziselwe ukwenza amabhande amayunifomu kanye nemishini ekhethekile yokuzivikela. Izindwangu ze-polyvinyl chloride zokugqoka ngokuvamile ziyizindwangu ezimuncayo (akukho ukumbozwa okudingekayo), njengamakepisi emvula, amabhulukwe ezingane, amajakhethi esikhumba okulingisa namabhuzu emvula ahlukahlukene. I-PVC isetshenziswa emikhiqizweni eminingi yezemidlalo nezokuzijabulisa, njengamathoyizi, amarekhodi nemikhiqizo yezemidlalo. Amathoyizi e-PVC nemikhiqizo yezemidlalo anezinga elikhulu lokukhula, futhi anezinzuzo ngenxa yezindleko zawo eziphansi zokukhiqiza nokubumba okulula.
9. Imikhiqizo eboshwe nge-PVC
Isikhumba sokwenziwa esisekelwayo senziwa ngokufaka i-PVC enamathiselwe endwangwini noma ephepheni, bese kufakwa ipulasitiki ngaphezu kuka-100°C. Ingenziwa futhi ngokugoqa i-PVC nezithasiselo zibe ifilimu kuqala, bese uyicindezela nge-substrate. Isikhumba sokwenziwa ngaphandle kokusekela siqondiswa ngokuqondile eshidini elithambile lokujiya okuthile nge-calender, bese licindezelwa ngephethini.Isikhumba sokwenziwa singasetshenziswa ukwenza amapotimende, izikhwama zemali, izembozo zezincwadi, amasofa nama-cushions emoto, kanye nesikhumba esiphansi, esisetshenziswa njengezinto zokubeka phansi izakhiwo.
10.PVC imikhiqizo yegwebu
Lapho i-PVC ethambile ixutshwa, inani elifanele le-ejenti ekhihlizayo liyengezwa ukwenza ishidi, elifakwe amagwebu bese lenziwa ipulasitiki eyigwebu, engasetshenziswa njengeziliphu zegwebu, izimbadada, ama-insoles, nezinto zokupakisha ezivimbela ukushaqeka. Ingase futhi isetshenziselwe ukwakha amashidi e-PVC aqinile anegwebu eliphansi nezinto ezinephrofayili ezisekelwe kuma-extruder, angasetshenziswa esikhundleni sokhuni. Iwuhlobo olusha lwempahla yokwakha.
11.PVC ishidi esobala
Engeza isilungisi somthelela nesiqinisi se-organotin ku-PVC, futhi ube ishidi elibonisa ngale ngemva kokuxutshwa, ukwenza ipulasitiki kanye ne-calendering. Ingenziwa ibe iziqukathi ezisobala ezinodonga oluncane noma isetshenziswe ekufakweni kwe-vacuum blister nge-thermoforming. Kuyinto enhle kakhulu yokupakisha impahla kanye nempahla yokuhlobisa.
12. Okunye
Iminyango namafasitela kuhlanganiswe ngezinto eziqinile ezinephrofayili. Kwamanye amazwe, iye yathatha umnyango nefasitela emakethe kanye nezicabha zokhuni namafasitela, amafasitela e-aluminium, njll; izinto zokhuni zokulingisa, izinto zokwakha ezithatha indawo yensimbi (enyakatho, ngasolwandle); iziqukathi ezingenalutho.
