I-PVC resin isetshenziswa kabanzi ezimbonini ezahlukahlukene.Ngokwe-polymerization degree ye-PVC resin, ubulukhuni bayo buhlukile.
Iphrofayili ye-PVC
Iphrofayili nephrofayili yizindawo ezisetshenziswa kakhulu i-PVC e-China, okubalelwa ku-25% wengqikithi yokusetshenziswa kwe-PVC.Ngokuyinhloko zisetshenziselwa ukwenza iminyango namafasitela nezinto zokonga amandla.Isicelo sabo sisakhula ngenani elikhulu ezweni lonke.Emazweni athuthukile, isabelo semakethe seminyango namafasitela epulasitiki siphezulu kakhulu, njenge-50% eJalimane, i-56% eFrance kanye ne-45% e-United States.
Ipayipi le-PVC
Phakathi kwemikhiqizo eminingi ye-PVC, ipayipi le-PVC liyindawo yesibili enkulu yokusetshenziswa, ehlanganisa cishe u-20% wokusetshenziswa kwayo.E-China, ipayipi le-PVC lakhiwe ngaphambi kwepayipi le-PE nepayipi le-PP, elinezinhlobonhlobo eziningi, ukusebenza okuhle kakhulu kanye nobubanzi bohlelo lokusebenza, elithatha isikhundla esibalulekile emakethe.
I-PVC membrane
Ukusetshenziswa kwe-PVC emkhakheni we-membrane ye-PVC kungena endaweni yesithathu, kubalwa cishe i-10%.Ngemuva kokuthi i-PVC ixutshwe futhi ifakwe ipulasitiki ngezithasiselo, ifilimu esobala noma enemibala enogqinsi olucacisiwe yenziwa nge-roll ezintathu noma i-4 roll calender.Ifilimu icutshungulwa ngale ndlela ukuze ibe ifilimu ehlelwe ngekhalenda.Ungakwazi futhi ukusika futhi ushise izikhwama zokupakisha uphawu, ama-raincoats, izindwangu zetafula, amakhethini, amathoyizi aphefumulayo, njll. Ifilimu esobala ebanzi ingasetshenziselwa ukushisa okushisa, i-plastic greenhouse nefilimu yepulasitiki.Ifilimu enwetshiwe ye-biaxially inezici zokuncipha okushisayo futhi ingasetshenziselwa ukupakishwa kokuncipha.
Izinto eziqinile ze-PVC namapuleti
I-PVC yengezwa nge-stabilizer, i-lubricant ne-filler.Ngemuva kokuxuba, amapayipi aqinile, amapayipi amise okukhethekile kanye namapayipi kathayela obubanzi obuhlukahlukene angakhishwa nge-extruder ye-downcomer, ipayipi lamanzi okuphuza, umkhono wocingo noma i-stair handrail.Amashidi anekhalenda angagqitshwa futhi acindezelwe ukuze enze amapuleti aqinile anobukhulu obuhlukahlukene.Ipuleti lingasikwa libe yisimo esidingekayo, bese lishiselwa emathangeni ahlukahlukene okugcina amakhemikhali angagqwali, imigudu yomoya kanye neziqukathi ezine-electrode ye-PVC nomoya oshisayo.
Imikhiqizo ethambile ye-PVC ejwayelekile
Ingakhishwa ibe ngamapayipi, izintambo, izintambo, njll. nge-extruder;Izimbadada zepulasitiki, ama-soles, ama-slippers, amathoyizi, izingxenye zezimoto, njll. zingenziwa ngomshini wokubumba umjovo onesikhunta esihlukahlukene.
Izinto zokupakisha ze-PVC
Imikhiqizo ye-PVC isetshenziselwa kakhulu ukupakisha iziqukathi ezahlukahlukene, amafilimu nezingcezu ezinzima.Iziqukathi ze-PVC zikhiqiza kakhulu amanzi amaminerali, amabhodlela esiphuzo nezimonyo, futhi zisetshenziselwa ukupakisha uwoyela ocolisisiwe.Ifilimu ye-PVC ingasetshenziselwa i-CO extrusion namanye ama-polymers ukukhiqiza imikhiqizo engabizi kakhulu eyenziwe nge-laminated kanye nemikhiqizo esobala enesithiyo esihle.Ifilimu ye-PVC ingabuye isetshenziselwe ukunwebeka noma ukupakisha okunciphayo, kanye nokupakisha omatilasi, indwangu, amathoyizi kanye nempahla yezimboni.
Amaphaneli we-PVC odongeni kanye naphansi
Amaphaneli odonga we-Pvc asetshenziswa kakhulu ukufaka amaphaneli odonga lwe-aluminium.Ngaphezu kwengxenye ye-PVC resin, ezinye izingxenye zamathayela aphansi e-PVC yizinto ezigaywe kabusha, izinto zokunamathisela, izigcwalisi nezinye izakhi, ezisetshenziswa kakhulu emhlabathini wesakhiwo sesikhungo sezindiza kanye nomhlabathi oqinile kwezinye izindawo.
Izimpahla zabathengi be-PVC
Isikhwama sempahla siwumkhiqizo wendabuko owenziwe nge-PVC.I-PVC isetshenziselwa ukwenza zonke izinhlobo zesikhumba sokulingisa, izikhwama zemithwalo kanye nemikhiqizo yezemidlalo, njengebhola lomnqakiswano, ibhola lezinyawo nebhola.Ingase futhi isetshenziselwe ukwenza umfaniswano namabhande emishini ekhethekile yokuzivikela.Izindwangu ze-PVC zokugqoka ngokuvamile ziyizindwangu ezimuncayo (ngaphandle kokumbozwa), njengama-poncho, amabhulukwe ezingane, amajakhethi esikhumba okulingisa namabhuzu emvula ahlukahlukene.I-Polyvinyl chloride isetshenziswa emikhiqizweni eminingi yezemidlalo nezokuzijabulisa, njengamathoyizi, amarekhodi kanye nezimpahla zemidlalo.Amathoyizi e-Polyvinyl chloride nezimpahla zezemidlalo zinokukhula okukhulu.Inenzuzo ngenxa yezindleko zayo eziphansi zokukhiqiza nokubumba okulula.
Imikhiqizo eyenziwe nge-PVC
Isikhumba sokwenziwa esine-substrate senziwa ngokufaka i-PVC endwangwini noma ephepheni bese kufakwa ipulasitiki ngaphezu kuka-100 ℃.I-PVC nezithasiselo nazo zingafakwa ngekhalenda zibe ifilimu, bese zicindezelwa nge-substrate.Isikhumba sokwenziwa ngaphandle kwe-substrate sifakwa ngokuqondile ku-calenders sibe amashidi athambile ogqinsi oluthile nge-calender, bese sicindezelwa ngamaphethini.Isikhumba sokwenziwa singasetshenziswa ukwenza amapotimende, izikhwama, izembozo zezincwadi, osofa namacushion ezimoto, kanye nesikhumba saphansi, esingasetshenziswa njengezinto zokugandaya ezakhiweni.
Imikhiqizo ye-PVC Foam
Lapho i-PVC ethambile ixutshwa, inani elifanele le-ejenti ekhihlizayo lifakwa eshidini ukwenza ipulasitiki eyigwebu, engasetshenziswa njengeziliphu zegwebu, izimbadada, ama-insoles, nezinto zokupakisha zokugoqa i-shockproof.Ingase futhi yakhelwe ibe amapuleti e-PVC aqinile acwebezelayo aphansi namaphrofayili asekelwe ku-extruder, angangena esikhundleni sokhuni.Yimpahla yokwakha entsha.
Ishidi esobala le-PVC
I-PVC ixutshwe, yenziwe ipulasitiki futhi ifakwe ngekhalenda ibe ishidi elibonisa ngale ngokwengeza isishintshi somthelela nesiqinisi se-organotin.I-Thermoforming ingasetshenziswa ukwenza iziqukathi ezisobala ezinodonga oluncane noma ukupakishwa kwe-vacuum blister.Kuyinto enhle kakhulu yokupakisha impahla kanye nempahla yokuhlobisa.
Abanye
Iminyango namafasitela kuhlanganiswe ngezinto eziqinile ezimise okukhethekile.Kwamanye amazwe, iye yahlala emakethe yezicabha namafasitela kanye nezicabha zamapulangwe, amafasitela namafasitela e-aluminium;Ukulingisa izinto zokhuni nezinto zokwakha zensimbi (eNyakatho nasolwandle);Isitsha esingenalutho.
I-Virtual circuit ingenye yezinsizakalo ezinikezwa inethiwekhi yokushintsha iphakethe (enye isevisi yedathagram).Ngamafuphi, kuwukusungula ukuxhumana okunengqondo okubonakalayo phakathi kwabasingathi bomsebenzisi ngokusebenzisa indlela yokulawula yangaphakathi yenethiwekhi, nokuqinisekisa ukulunga nokulandelana kokudlulisa amaphakethe kuyo.Isekhethi ebonakalayo kufanele isungulwe futhi isuswe ngaphambi nangemva kokuxhumana.Isekethe ye-virtual ehlala njalo iyisekhethi ebonakalayo esungulwe ngesikhathi sokuqaliswa kwenethiwekhi, futhi isifunda esibonakalayo sigcinwa ngaso sonke isikhathi.
