I-ACR, Ama-Plasticizer, Ama-Lubricant: Izihluthulelo ezi-3 zekhwalithi kanye nokucutshungulwa kwe-PVC

Imikhiqizo ye-PVC ihlanganiswe kahle kuzo zonke izingxenye zokuphila kwethu kwansuku zonke, kusukela kumapayipi athutha amanzi emakhaya ethu kuya kumathoyizi anemibala aletha injabulo ezinganeni, kanye nakumapayipi aguquguqukayo ezindaweni zezimboni kuya phansi okunesitayela emakamelweni ethu okuphumula. Kodwa-ke, ngemuva kokusetshenziswa kwayo kabanzi kukhona umbuzo: yini eyenza le mikhiqizo ikwazi ukufeza inhlanganisela ephelele yokusebenziseka kalula, ukubukeka okukhangayo, kanye nokusebenza okuqinile? Namuhla, sizokwembula izinto ezintathu ezibalulekile ezenza lokhu kwenzeke - i-ACR, ama-plasticizer, kanye nezinto zokugcoba zangaphakathi.

I-ACR: Isithuthukisi Sokucubungula kanye Nokukhuthaza Ukusebenza​

I-ACR, noma i-acrylic copolymer, iyisengezo esibalulekile esidlala indima ebalulekile ekuthuthukiseni izakhiwo zokucubungula kanye nokusebenza kwemikhiqizo ye-PVC. Ngesikhathi sokucubungula i-PVC, ukungezwa kwe-ACR kunganciphisa ngempumelelo i-viscosity yokuncibilika, ngaleyo ndlela kuthuthukiswe ukugeleza kwezinto. Lokhu akugcini nje ngokwenza inqubo yokucubungula ibe lula, kunciphisa ukusetshenziswa kwamandla kanye nesikhathi sokukhiqiza, kodwa futhi kusiza ekuthuthukiseni amandla omthelela wemikhiqizo yokugcina, okwenza ihlale isikhathi eside ekusetshenzisweni okungokoqobo.​

Uma i-PVC icutshungulwa emazingeni okushisa aphezulu, ivame ukuwohloka ngokushisa, okungathinta ikhwalithi yemikhiqizo. I-ACR ingasebenza njengesiqinisi sokushisa ngezinga elithile, ibambezele ukonakala kokushisa kwe-PVC futhi iqinisekise ukuzinza kwezinto ngesikhathi sokucubungula. Ngaphezu kwalokho, i-ACR ingathuthukisa nokuphela kobuso bemikhiqizo ye-PVC, ibenze babukeke bekhanga kakhulu.​

Ama-Plasticizers: Umhlinzeki Wokuguquguquka Nokubumbana

Ama-plasticizer angenye ingxenye ebalulekile emikhiqizweni ye-PVC, ikakhulukazi abangela ukwandisa ukuguquguquka kanye nokuqina kwe-PVC. I-PVC iyi-polymer eqinile ngesimo sayo esimsulwa, futhi kunzima ukuyicubungula ibe yimikhiqizo eguquguqukayo. Ama-plasticizer angangena ezintanjeni zama-molecule e-PVC, anciphise amandla aphakathi kwama-molecule, ngaleyo ndlela enze izinto ziguquguquke kakhudlwana.​

Izinhlobo ezahlukene ze-plasticizers zinezimpawu ezahlukene kanye nezimo zokusetshenziswa. Isibonelo, i-phthalate plasticizers yake yasetshenziswa kabanzi ngenxa yomphumela wayo omuhle we-plasticizing kanye nezindleko eziphansi. Kodwa-ke, ngokugcizelela okwandayo ekuvikelweni kwemvelo kanye nempilo, i-plasticizers enobungane nemvelo njenge-citric acid esters kanye ne-adipates isithandwa kakhulu. Lawa ma-plasticizer anobungane nemvelo awagcini nje ngokuba nezakhiwo ezinhle ze-plasticizing kodwa futhi ahlangabezana nezindinganiso eziqinile zemvelo nokuphepha, okwenza afaneleke ukusetshenziswa ekupakisheni kokudla, kumadivayisi ezokwelapha, kanye nemikhiqizo yezingane.​

Inani le-plasticizer engeziwe nalo linomthelela omkhulu ezimpahleni zemikhiqizo ye-PVC. Inani elikhulu le-plasticizer engeziwe lizokwenza imikhiqizo iguquguquke kakhulu kodwa linganciphisa amandla ayo okusebenza. Ngakho-ke, ekukhiqizweni kwangempela, uhlobo olufanele kanye nenani le-plasticizer kudingeka kukhethwe ngokuya ngezidingo ezithile zemikhiqizo.​

Izithambisi Zangaphakathi: Isithuthukisi Sokugeleza Nokupholisha Okungaphezulu​·

Izithambisi zangaphakathi zibalulekile ekuthuthukiseni ukugeleza kokucubungula kwe-PVC nokuthuthukisa ukukhanya kobuso bemikhiqizo. Zinganciphisa ukungqubuzana phakathi kwama-molecule e-PVC, zenze ukugeleza kwezinto kube lula ngesikhathi sokucubungula, okubaluleke kakhulu emikhiqizweni ye-PVC enomumo oyinkimbinkimbi.​

Ngesikhathi sokuxuba nokucubungula izinto ze-PVC, amafutha angaphakathi angasiza izingxenye ezahlukene ukuthi zixubane ngokulinganayo, okuqinisekisa ukuhambisana kwekhwalithi yomkhiqizo. Ngaphezu kwalokho, anganciphisa nokunamathelana phakathi kwezinto nezinto zokucubungula, anciphise ukuguguleka kwemishini futhi andise isikhathi sayo sokusebenza.​

Ngaphezu kwalokho, amafutha okugcoba angaphakathi angathuthukisa ukukhanya kobuso bemikhiqizo ye-PVC, okwenza ibukeke inhle kakhulu futhi isezingeni eliphezulu. Lokhu kubaluleke kakhulu emikhiqizweni ye-PVC enezidingo eziphezulu zokubukeka, njengamaphaneli okuhlobisa nezinto zokupakisha.

Ukusebenzisana Kwezihluthulelo Ezintathu

Ama-ACR, ama-plasticizer, kanye nezinto zokugcoba zangaphakathi azisebenzi ngokuzimela; kunalokho, ziyasebenzisana ukuqinisekisa ukuthi imikhiqizo ye-PVC inezakhiwo ezinhle kakhulu zokucubungula, ukubukeka okuhle, kanye nokusebenza okuqinile.

I-ACR ithuthukisa ukugeleza kokucubungula kanye namandla okushaya, ama-plasticizer ahlinzeka ngokuguquguquka okudingekayo kanye nokuqina, kanti amafutha angaphakathi enza ngcono ukugeleza kokucubungula futhi athuthukise ukukhanya kobuso. Ndawonye, ​​​​zenza imikhiqizo ye-PVC ihlangabezane nezidingo ezahlukahlukene zezicelo ezahlukene.​

Ekuphetheni, i-ACR, ama-plasticizer, kanye nezinto zokugcoba zangaphakathi ziyizihluthulelo ezintathu ezibalulekile "zokucubungula okulula + ubuhle obuphezulu + ukusebenza okuqinile" kwemikhiqizo ye-PVC. Ngokuthuthuka okuqhubekayo kobuchwepheshe, ukusebenza kwalezi zithasiselo kuzothuthukiswa kakhulu, okuzoqhuba ukusungula izinto ezintsha okuqhubekayo kanye nentuthuko yomkhakha wemikhiqizo ye-PVC, okuletha imikhiqizo ye-PVC esezingeni eliphezulu nehlukahlukene ezimpilweni zethu.
