I-PVC Resin, Ilungele Ukuthunyelwa ~

Isicelo

1. Amaphrofayili e-PVC

Amaphrofayili namaphrofayili yizindawo ezinkulu zokusetshenziswa kwe-PVC ezweni lami, ezibalelwa ku-25% wengqikithi yokusetshenziswa kwe-PVC. Ngokuyinhloko zisetshenziselwa ukwenza iminyango namafasitela nezinto zokonga amandla, futhi umthamo wazo wokufaka isicelo usakhula kakhulu ezweni lonke. Emazweni athuthukile, isabelo semakethe seminyango namafasitela epulasitiki siphezulu kakhulu, njengamaphesenti angama-50 eJalimane, angama-56% eFrance, nama-45% e-United States.

2. PVC amapayipi

Phakathi kwemikhiqizo eminingi ye-PVC, amapayipi e-PVC ayindawo yesibili enkulu yokusetshenziswa, ehlanganisa cishe u-20% wokusetshenziswa kwayo. Ezweni lami, amapayipi e-PVC athuthukiswa ngaphambi kwamapayipi e-PE namapayipi e-PP, anezinhlobo eziningi, ukusebenza okuhle kakhulu, kanye nezinhlobonhlobo zokusetshenziswa, ezithatha isikhundla esibalulekile emakethe.

3. Ifilimu ye-PVC

Ukusetshenziswa kwe-PVC emkhakheni wefilimu we-PVC kukleliswe endaweni yesithathu, okubalelwa cishe ku-10%. Ngemuva kokuthi i-PVC ixutshwe nezithasiselo kanye nepulasitiki, i-three-roll noma i-four-roll calender isetshenziselwa ukwenza ifilimu esobala noma enemibala yogqinsi olucacisiwe. Ifilimu icutshungulwa ngale ndlela ukuze ibe yifilimu ehlelwe ngokwekhalenda. Ingase futhi icutshungulwe ibe izikhwama zokupakisha, ama-raincoat, izindwangu zetafula, amakhethini, amathoyizi aphefumulayo, njll. ngokusika nokuvala ukushisa. Amafilimu obala abanzi angasetshenziselwa izindawo zokugcina izithombo, zokugcina izithombo zepulasitiki namafilimu aphansi. Ifilimu enwetshiwe ye-biaxially ingasetshenziselwa ukupakisha ukushwabana ngenxa yezimpawu zayo zokuncipha kokushisa.

4. Izinto eziqinile ze-PVC namashidi

Engeza iziqinisi, okothambisa kanye nezigcwalisi ku-PVC. Ngemva kokuxuba, i-extruder ingakhipha amapayipi ahlukahlukene aqinile, amapayipi amise okwekhethekile, namapayipi kathayela, asetshenziswa njengamapayipi endle, amapayipi amanzi okuphuza, ama-wire casings noma ama-handrails. Amashidi agoqwe agqigqana futhi acindezelwe ashisayo ukuze enze amashidi aqinile anobukhulu obuhlukahlukene. Amashidi angasikwa abe yisimo esidingekayo, bese kusetshenziselwa izinduku zokushisela ze-PVC ukushisela amathangi okugcina amelana namakhemikhali ahlukahlukene, imigudu yomoya neziqukathi ezinomoya oshisayo.

5. Imikhiqizo ethambile ye-PVC ejwayelekile

Ukusebenzisa i-extruder, ingakhishwa ibe ngamapayipi, izintambo, izintambo, njll.; usebenzisa umshini wokubumba umjovo onesikhunta esihlukahlukene, ungenziwa izimbadada zepulasitiki, amasoli, ama-slippers, amathoyizi, izingxenye zezimoto, njll.

6. Izinto zokupakisha ze-Polyvinyl chloride

Imikhiqizo ye-polyvinyl chloride isetshenziselwa ikakhulukazi ukupakisha iziqukathi ezahlukahlukene, amafilimu namashidi aqinile. Iziqukathi ze-PVC zisetshenziselwa ikakhulukazi ukukhiqiza amanzi amaminerali, iziphuzo, namabhodlela ezimonyo, futhi zisetshenziselwa ukupakisha amafutha acolisisiwe. Ifilimu ye-PVC ingasetshenziselwa ukukhipha ngokuhlanganyela namanye ama-polymers ukukhiqiza imikhiqizo engabizi kakhulu eyenziwe nge-laminated, kanye nemikhiqizo esobala enezakhiwo ezinhle zokuvimba. Ifilimu ye-PVC ingabuye isetshenziselwe ukunwetshwa noma ukupakisha okuncipha ukushisa, futhi isetshenziselwa ukupakisha omatilasi, indwangu, amathoyizi, kanye nezimpahla zasembonini.

7. PVC siding kanye flooring

I-PVC siding isetshenziselwa ngokuyinhloko ukufaka esikhundleni se-aluminium siding. Ngaphezu kwengxenye ye-PVC resin, izingxenye ezisele zamathayela aphansi we-PVC yizinto ezigaywe kabusha, izinto zokunamathisela, izigcwalisi, nezinye izakhi. Zisetshenziswa kakhulu endaweni eqinile yamatheminali esikhumulo sezindiza nakwezinye izindawo.

8. Izimpahla zansuku zonke ze-PVC zabathengi

Izikhwama zemithwalo ziyimikhiqizo yendabuko eyenziwe nge-PVC. I-PVC isetshenziselwa ukwenza izikhumba zokulingisa ezihlukahlukene zezikhwama zemithwalo, imikhiqizo yezemidlalo, njengebhola lombhoxo, ibhola lezinyawo, kanye nebhola lombhoxo. Ingase futhi isetshenziselwe ukwenza amabhande amayunifomu kanye nemishini ekhethekile yokuzivikela. Izindwangu ze-PVC zezingubo ngokuvamile ziyizindwangu ezimuncayo (akukho ukunamathela okudingekayo), njengamajazi emvula, amabhulukwe ezingane, amajakhethi esikhumba okulingisa, namabhuzu emvula ahlukahlukene. I-Polyvinyl chloride isetshenziswa emikhiqizweni eminingi yezemidlalo nezokuzijabulisa, njengamathoyizi, amarekhodi kanye nemishini yezemidlalo. Amathoyizi e-Polyvinyl chloride nemishini yezemidlalo anezinga elikhulu lokukhula, futhi anenzuzo ngenxa yezindleko zawo eziphansi zokukhiqiza nokubumba okulula.

9. Imikhiqizo eboshwe nge-PVC

Isikhumba sokwenziwa esisekelwayo senziwe ngokufaka i-PVC enamathiselwe endwangwini noma ephepheni, bese kufakwa ipulasitiki ngaphezu kuka-100°C. Ingenziwa futhi ngokuqala ngekhalenda ye-PVC nezithasiselo zibe ifilimu, bese uyicindezela ngokusekelwa. Isikhumba sokwenziwa ngaphandle kokusekela siqondiswa ngokuqondile eshidini elithambile logqinsi oluthile nge-calender, bese licindezelwa ngephethini. Isikhumba sokwenziwa singasetshenziswa ukwenza amapotimende, izikhwama, izembozo zezincwadi, osofa namakhushini ezihlalo zemoto, njll., kanye nesikhumba saphansi, esisetshenziswa njengento yokubeka phansi izakhiwo.

10. Imikhiqizo ye-PVC yegwebu

Lapho i-PVC ethambile ixutshwa, inani elifanele le-ejenti ekhihlizayo liyengezwa ukwenza ishidi, elifakwe amagwebu epulasitiki eyigwebu, elingasetshenziswa njengeziliphu zegwebu, izimbadada, ama-insoles, nezinto zokupakisha ezivimbela ukushaqeka. Ingenziwa futhi ibe amashidi e-PVC aqinile anegwebu eliphansi kanye namaphrofayili asekelwe ku-extruder, engashintsha izinkuni futhi iwuhlobo olusha lwezinto zokwakha.

11. Ishidi elisobala le-PVC

I-PVC yengezwa ngesiguquli somthelela kanye ne-organic tin stabilizer, futhi iba ishidi elibonisa ngale ngemva kokuxutshwa, ukwenza ipulasitiki kanye ne-calendering. Ingenziwa ibe iziqukathi ezisobala ezinodonga oluncane noma isetshenziselwe ukupakishwa kwe-vacuum blister nge-thermoforming, futhi iyinto enhle kakhulu yokupakisha nezinto zokuhlobisa.

12. Abanye

Iminyango namafasitela kuhlanganiswe ngezinto eziqinile ezimise okukhethekile. Kwamanye amazwe, baye bahlala emakethe yomnyango namafasitela kanye neminyango namafasitela ngokhuni, amafasitela e-aluminium, njll; izinto zokhuni zokulingisa, izinto zokwakha ezithatha indawo yensimbi (enyakatho, ngasolwandle); iziqukathi ezingenalutho.
