Umlawuli we-PVC ogwebu ugwebu unokusinceda sizise iipropati ezilungileyo ngexesha lemveliso kunye nokusetyenzwa kwe-PVC, okwenza ukuba iimpendulo zethu ziqhube ngcono kwaye zivelise iimveliso esizifunayo. Nangona kunjalo, kufuneka sinikele ingqalelo kwiindawo ezininzi zolawulo lwemizi-mveliso xa siyivelisa, ukuze iimpendulo zethu ziqhube ngcono.
Ukubunjwa kogwebu lweplastiki yePVC yokulawula ugwebu lwahlulwe lwaba ziinkqubo ezintathu: ukubunjwa kondoqo weqamza, ukwandiswa kondoqo weqamza, kunye nokuqiniswa komzimba wogwebu. Kumaphepha e-PVC amagwebu anee-agent ezongezelelweyo zekhemikhali, ukwandiswa kwe-bubble nuclei kunempembelelo eqinisekileyo kumgangatho wephepha le-foam. I-PVC yeyeemolekyuli zetsheyini ezithe tye ezinamatyathanga amafutshane emolekyuli kunye namandla aphantsi anyibilikayo. Ngexesha lenkqubo yokwandiswa kwe-bubble core ibe ngamaqamza, ukunyibilika akwanelanga ukugubungela amaqamza, kwaye irhasi ilungele ukuphuphuma kwaye idibanise kwiibhulu ezinkulu, ukunciphisa umgangatho wemveliso yamaphepha e-foam.
Eyona nto iphambili ekuphuculeni umgangatho wePVC zokuguqula ugwebu kukuphucula amandla okunyibilika kwePVC. Ukusuka kuhlalutyo lweempawu zokusetyenzwa kwemathiriyeli yepolymer, kukho iindlela ezahlukeneyo zokuphucula amandla okunyibilika kwePVC, kodwa eyona ndlela ilungileyo kukongeza izongezo ezandisa amandla okunyibilika kunye nokunciphisa ubushushu bokusebenza. I-PVC yeyezixhobo ze-amorphous, kwaye amandla ayo okunyibilika ayancipha ngokunyuka kweqondo lokushisa lokunyibilika. Ngokwahlukileyo, amandla ayo okunyibilika ayanda ngokuhla kweqondo lokushisa lokunyibilika, kodwa umphumo wokupholisa ulinganiselwe kwaye usebenza kuphela njengomsebenzi oncedisayo. I-ACR processing agents zonke zinefuthe lokuphucula amandla okunyibilika, okunyuka ngokunyuka komxholo wokulawula ogwebu. Ngokubanzi, nje ukuba isikrufu sinokusasazwa okwaneleyo kunye nekhono lokuxuba, ukongeza i-viscosity ephezulu yokuguqula amagwebu kunempembelelo ebaluleke ngakumbi ekuphuculeni amandla okunyibilika.
Oku ngasentla sisingeniso esifutshane kwiingongoma eziphambili zolawulo lwenkqubo ye-foam ye-PVC i-foam modifiers. Xa sizivelisa, kufuneka sinikele ingqalelo ekubunjweni, ukwandiswa, kunye nokunyangwa kwe-nuclei ye-bubble yabo kwaye silawule ngokungqongqo.
