Imikhiqizo ye-PVC isetshenziswa kakhulu ekuphileni kwansuku zonke, kodwa ingase ibe nezinkinga ezithile ngesikhathi sokusetshenziswa.Namuhla, umkhiqizi weSainuo i-polyethylene waxkuzokuthatha ukuthi ufunde mayelana nenkinga yokwenza mhlophe kwemikhiqizo ye-PVC.

Lapho imikhiqizo ye-PVC ichayeka ekushiseni ngaphandle, ngenxa yemiphumela yomswakama, i-carbon dioxide, i-sulphur dioxide, nokukhanya okusemoyeni, izobonisa into emhlophe, ikakhulukazi ngenxa yezizathu ezintathu ezilandelayo:
1. Ukuba mhlophe ngemva kokucwiliswa emanzini
Izinhlobo eziningi zemikhiqizo ye-PVC esobala ibonisa ukubukeka kwenkungu emhlophe lapho ithintana namanzi noma isitimu isikhathi eside.Imikhiqizo ethambile inamandla kakhulu kuneqinile.Ngenxa yokucwiliswa kwamanzi, ama-plasticizers, stabilizers, njll. ziwa zisuka ku-PVC bese zingena emanzini, zenze izimvula ezinama-hydrated ngaphezulu (okuthinta ukubonakala).Ngisho noma amanzi acwilisiwe engasekho, ama-plasticizers nama-stabilizers awakwazi ukubuyiselwa esimweni sawo sokuqala.Ngokukhuphula izinga lokushisa kuphela lapho kungabuyiselwa ukuhambisana phakathi kwama-plasticizer nama-stabilizer ngaphambi kokuthi kukhanye.
2. Ukuba mhlophe ngemva kokuchayeka elangeni
Imikhiqizo ye-PVC echayeke elangeni ngaphandle ingabonisa nokuba mhlophe ngenxa yemiphumela yomswakama, i-carbon dioxide, i-sulphur dioxide, nokukhanya emoyeni.Lokhu kuhlobene nokuhambisana kwama-stabilizers.Ezinsipho zensimbi, ama-benzoate ahambisana kahle ne-PVC abonisa ukumhlophe okuncane kune-stearate.I-Organic tin akulula ukuyenza ibe mhlophe, futhi i-organic tin equkethe isibabule ihamba phambili, ilandelwa usawoti we-lauric acid nosawoti we-maleate.Ukwengeza iziqinisi ukukhanya, i-phosphite esters, iziqinisi eziyinhlanganisela yoketshezi, njll. kungavimbela noma kudambise okwenzekayo okuba mhlophe kwe-PVC okubangwa ukuchayeka elangeni.

Imikhiqizo eqinile ye-PVC izophenduka ibe mhlophe ngemva kokuchayeka e-Florida noma kwezinye izindawo eziswakeme, kodwa ngeke ihlale imhlophe lapho ivezwa e-Arizona.Ngakho-ke, umswakama yisimo esikhuthaza ukuba mhlophe kwe-PVC ngokuchayeka elangeni.
3. Ukucindezeleka mhlophe
Ukwenza mhlophe kwengcindezi kubhekisela kwinto yokwenza mhlophe ezindaweni zasendaweni zemikhiqizo ye-PVC, njengokugoba, ama-crease, nezindawo ezinwebekayo, ngaphansi kwesenzo samandla angaphandle ayimishini.
Lokhu kungase kube ngenxa yokushintsha kwesakhiwo samangqamuzana okubangelwa amandla angaphandle, ukuma kweketango le-polymer molecular, ukushintsha kwe-PVC density, kanye nokubonakala kwe-voids phakathi kwamanye ama-molecule ukuze enze ukuhlakazeka kokukhanya, okwenza imikhiqizo ye-PVC ibonakale imhlophe.

4. Okunye ukwenza mhlophe
Ngesikhathi sokucutshungulwa kwemikhiqizo esobala ye-PVC, uma kusetshenziswa inani eliningi lokuthambisa, ama-lubricant precipitates amaningi angabangela ukuthi imikhiqizo ekhanyelayo ikhiqize i-turbidity emhlophe, ngezinye izikhathi ebizwa ngokuthi ukumhlophe.
Le nto yokuba mhlophe ivamise ukuphumela ekubonakaleni kwengcina njengezinto ebusweni bomkhiqizo.Isixazululo siwukunciphisa inani lokuthambisa elisetshenziswayo noma ukushintshela ku-lubricant ehambisana kangcono, ukuze kuzuzwe ibhalansi phakathi kokugcobisa kwangaphakathi nangaphandle kwefomula.
Ukuze uthole imininingwane eyengeziwe, sicela usithinte!
