I-Barium zinc stabilizer isetshenziselwa ini?

I-Barium-zinc stabilizerluhlobo lwe-stabilizer evame ukusetshenziswa embonini yepulasitiki, engathuthukisa ukuzinza kokushisa kanye nokuzinza kwe-UV yezinto ezihlukahlukene zepulasitiki. Lezi ziqinisi zaziwa ngokukwazi kwazo ukuvimbela izinto zepulasitiki ekucekeleni phansi, zizenze zilungele ukusetshenziswa kwangaphandle kanye nezindawo ezishisa kakhulu. Kulesi sihloko, sizohlola ukusetshenziswa kanye nezinzuzo ze-barium zinc stabilizers embonini yepulasitiki.

I-Barium-zinc stabilizers ivame ukusetshenziswa ekukhiqizeni i-PVC (i-polyvinyl chloride) nezinye izinto zepulasitiki. I-PVC iyi-polymer ye-thermoplastic esetshenziswa kabanzi esetshenziswa ezintweni ezahlukahlukene, kufaka phakathi izimboni zokwakha, zokupakisha nezimboni zezimoto. Kodwa-ke, kuyaziwa ukuthi i-PVC isengozini yokuwohloka lapho ichayeke ekushiseni nasemisebeni ye-UV, okuholela ekushintsheni kwezakhiwo zayo zemishini nezomzimba. Yilapho ama-barium zinc stabilizer engena khona.

Inhloso eyinhloko yokusebenzisa i-barium zinc stabilizers ku-PVC nezinye izinto zepulasitiki ukuvimbela ukuwohloka ngenxa yokushisa nokuvezwa kwe-UV. Iqhaza lalezi ziqinisi ukuqothula ama-radicals mahhala akhiqizwa ngesikhathi sokuwohloka, ngaleyo ndlela kuvinjwe ukusabela kwamaketanga okuholela ekwephukeni kwamaketanga e-polymer. Ngenxa yalokho, izinto zepulasitiki zihlala zizinzile futhi zigcina izakhiwo zazo ngisho nalapho zivezwe ezimweni ezinzima zemvelo.

Enye yezinzuzo eziyinhloko zokusebenzisa i-barium zinc stabilizers ukuqina kwazo okuhle kakhulu kokushisa. Lokhu kubenza bafaneleke kakhulu izinhlelo zokusebenza lapho izinto zepulasitiki zivezwa emazingeni okushisa aphezulu, njengezinto zokwakha, izingxenye zezimoto kanye nezintambo zikagesi. Ngaphezu kwalokho, i-barium-zinc stabilizers inokumelana okuhle kakhulu kwe-UV, okuyenza ilungele ukusetshenziswa kwangaphandle lapho izinto zepulasitiki zivezwa elangeni.

Ngaphezu kokuzinza kwe-thermal kanye ne-UV, izinzile ze-barium zinc zinikeza ezinye izinzuzo. Ayabiza futhi asebenza kahle, adinga imithamo ephansi uma kuqhathaniswa nezinye izinhlobo zokuzinzisa. Lokhu kusho ukuthi abakhiqizi badinga kuphela ukusebenzisa inani elincane lokusimamisa ukuze bafinyelele izinga elifiswayo lokusimamisa, ukonga izindleko kanye nokwenza ngcono ukusebenza komkhiqizo kukonke.

Ukwengeza, ama-barium-zinc stabilizer ayaziwa ngokuhambisana kwawo nezinhlobonhlobo zezithasiselo nezimo zokucubungula. Lokhu kubenza babe nezinto ezihlukahlukene futhi kulula ukuhlanganisa ezinqubweni zokukhiqiza, okuvumela ukuguquguquka okukhulu ekukhiqizeni izinto zepulasitiki. Lokhu kuguquguquka nokuhambisana kwenza izinzinzi ze-barium zinc zibe yisinqumo esidumile kubakhiqizi abaningi bepulasitiki.

Kuyafaneleka futhi ukuqaphela ukuthi i-barium-zinc stabilizers ibhekwa njengobungani bemvelo uma iqhathaniswa nezinye izinhlobo zokuzinzisa, njengeziqinisi ezisekelwe kumthofu. Njengoba ukuqwashisa ngezindaba zemvelo kanye nemithethonqubo kukhula, i-barium-zinc stabilizers iye yanda kakhulu njengendlela eqhubekayo nemvelo yokumisa izinto zepulasitiki.

I-Barium-zinc stabilizers isetshenziswa kabanzi embonini yepulasitiki ngenxa yekhono labo lokuthuthukisa ukuzinza kwe-thermal ne-UV, ukuvimbela ukuwohloka, nokugcina izakhiwo zezinto zepulasitiki. Ukusebenza kwayo okuphezulu, ukuphumelela kwezindleko kanye nobungane bemvelo kwenza kube ukukhetha okudumile kwezinhlelo zokusebenza lapho ukuzinza nokuqina kubalulekile. Njengoba isidingo sezinto zepulasitiki ezisebenza kahle kakhulu siqhubeka sikhula, i-barium-zinc stabilizers kulindeleke ukuthi ibambe iqhaza elibalulekile ekuhlangabezaneni nalezi zidingo ngenkathi ihlangabezana nezindinganiso zokusimama kanye nokulawula.
