Yintoni umahluko phakathi kwezinto zokuncedisa ukucubungula i-PVC kunye nezilawuli ze-PVC ezikhupha amagwebu?

Iiregulator ze-PVC foaming ziyinxalenye yohlobo olunye lweemveliso ze-PVC processing aids. Kwinkqubo yokucubungula izixhobo ze-PVC, kufuneka kongezwe iimveliso ezininzi ze-PVC processing aids ukuze zidlale indima ethile, kwaye olunye uhlobo lwemveliso ziiregulator ze-PVC foaming. Iiregulator ze-PVC processing ziquka iintlobo ezahlukeneyo zeemveliso, ezinje ngee-plasticizers, izibambisi, ii-pigment, njl. Ke ngoko, iiregulator ze-PVC foaming luhlobo lwe-PVC processing aid.

Kwimarike yokucubungula i-PVC yangoku, izinga lokusetyenziswa kwabalawuli be-PVC foaming liphezulu kakhulu. Umlawuli we-PVC foaming sisixhobo sokulungisa i-PVC esifuna ukulungisa uxinano lwe-pore ngexesha le-atomization effect yezinto ze-PVC. Izinto ze-PVC kufuneka ziphathwe nge-foaming ngexesha lokusetyenziswa, kwaye umgangatho kunye nobungakanani be-foaming ngexesha lokucubungula i-foaming bunokudlala indima ethile kumgangatho kunye nokusebenza kwezinto ze-PVC ezicutshungulwe zibe ziimveliso ezigqityiweyo. Xa usebenzisa abalawuli be-PVC foaming, kuyimfuneko ukuchonga igama lophawu, ukusebenza kwemveliso, kunye nohlobo lwezixhobo ze-PVC zokongeza izixhobo zokucubungula i-PVC, kuba igama lophawu lwezixhobo zokucubungula lihambelana nezinto ze-PVC. Ngokusebenzisa amagama eempawu ezifanelekileyo zezixhobo zokucubungula i-PVC kunye nokulawula ngokupheleleyo idosi, sinokuphucula umgangatho kunye nefuthe le-atomization xa kucutshungulwa iimveliso ze-PVC.

Ubunzima beemolekyuli zezixhobo zokucubungula i-PVC bunxulumene nesiphumo se-atomization ngexesha lokucubungula. Ke ngoko, xa senza ukucubungula i-PVC, akufuneki sikhethe kuphela izixhobo zokucubungula i-PVC ezikumgangatho ophezulu, kodwa sikhethe nezixhobo zokucubungula i-PVC ezinemigangatho efanayo ukuqinisekisa ukhuseleko. Kuba ukuba izixhobo zokucubungula i-PVC ezikhethiweyo azihlangabezani nemigangatho emiselweyo, inkunkuma iya kuveliswa, nto leyo eya kunyusa kakhulu iindleko zokucubungula. Kufuneka sikhethe izixhobo zokucubungula i-PVC ezikumgangatho ophezulu xa sithenga.

Kakade ke, kukwakho neemveliso ezininzi zokuncedisa ukucubungula i-PVC ezikumgangatho ophantsi ezizalise imarike okwangoku, ngoko ke xa sikhetha, kufuneka sikhethe iimveliso zokuncedisa ukucubungula i-PVC eziveliswa ngabavelisi abasemthethweni.
