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
Faka ama-stabilizers, ama-lubricant nama-fillers ku-PVC, futhi ngemva kokuxuba, sebenzisa i-extruder ukukhipha amapayipi aqinile, amapayipi amise okwesipesheli, namapayipi kathayela angama-diameter ahlukahlukene, angasetshenziswa njengamapayipi endle, amapayipi amanzi okuphuza, ama-wire casings noma ama-handrails. .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 ukunamathela 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 kokusekelwa siqondiswa ngokuqondile eshidini elithambile logqinsi oluthile ngekhalenda, bese licindezelwa ngephethini.Isikhumba sokwenziwa singasetshenziswa ukwenza amapotimende, izikhwama zemali, izembozo zezincwadi, osofa namakhushini emoto, kanye naphansi. isikhumba, esisetshenziswa njengezinto zokubeka phansi ezakhiweni.
10.PVC imikhiqizo yegwebu
Lapho i-PVC ethambile ixutshwa, inani elifanele le-ejenti ekhihliza igwebu liyengezwa ukuze kwakhiwe ishidi, elifakwe amagwebu futhi lenziwe 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.
