PVC umnyango ikhethini iminyaka emibili hhayi yellowing isimiso

Ikhethini lomnyango lisetshenziswa yonke imindeni, ikakhulukazi ehlobo elishisayo, omiyane baningi, ukukhanya kunamandla kakhulu, ngakho-ke ukuthengiswa kwamakhethini emnyango wehlobo kuqondile, izinga lomkhiqizo liyisiqinisekiso esibalulekile. Kunezinhlobo eziningi zezitayela zekhethini zomnyango. Ehlobo, sivame ukubona ikhethini lomnyango othambile we-PVC. njalo, esobala umnyango kwesihenqo kunenkinga kuqhathaniswa ezivamile, okungukuthi, kulula yellowing, ukuguga ngokushesha, futhi sina kuthinta ukubukeka imikhiqizo, avele lolu hlobo mkhuba angavumela umsebenzisi ikhanda elibuhlungu, more let soft umnyango ikhethini umenzi engenakuzisiza. Abakhiqizi abaningi bebelokhu befuna i-axiliary ukushintsha le nkinga, futhi bazama okuningi, abanye ngemva kokusetshenziswa nakuba bethuthukisiwe, kodwa umphumela awulungile.

Isizathu salokhu ukuthi ikhethini le-PVC liphuzi,Ikakhulukazi ngenxa yokuthi ikhethini lomnyango lingaphandle, ilanga lingakhanyiswa ngokuqondile, ngokuvamile izinyanga ezintathu noma ngaphezulu zizovela into ephuzi, iphuzi elide elibi kakhulu. Lesi simo sibangelwa ikakhulukazi emisebeni ye-ultraviolet elangeni, eyacekela phansi ukwakheka kwamangqamuzana ekhethini le-PVC, ukuze i-chlorine epholile equkethwe kwisakhiwo se-PVC ekukhanyeni kwesikhathi eside kanye ne-oxidation izosheshisa ukubola kokuphuzi okufana ne-PS ne-PU. Lokhu kungancishiswa ngokungeza inani elincane lama-antioxidants kanye neziqinisi ezikhanyayo phakathi nesigaba sokuhlanganisa. Izengezo ezivamile zama-Antioxidants 1010 kanye ne-UV-531 ziyinhlanganisela evimbela ukuguga evame kakhulu emikhiqizweni ye-PVC. Sicela ubhekisele ku.
