Ukusetshenziswa komlawuli we-PVC foaming:
Ukugqwala kwezinto ze-PVC kuzokwenza ukusatshalaliswa kwama-molecule e-PVC kufane kakhudlwana. Yenza ikhwalithi yemikhiqizo ye-PVC ibe nomqondo oqondile. Ishidi le-PVC elenziwe nge-PVC foaming regulator linesakhiwo esihle kakhulu esizimele. Ngezinye izikhathi, ngenkathi sisebenzisa i-PVC foaming regulator, sisebenzisa nezinye izi-foaming accelerators. Izi-foaming accelerators zifaka ama-metal oxides afana ne-zinc oxide kanye ne-lead oxide, usawoti we-organic acid njenge-zinc stearate, kanye ne-urea derivatives.
Izinzuzo zomlawuli we-PVC foaming:
Umlawuli we-PVC foaming unazo zonke izici zezinsiza zokucubungula i-PVC, onesisindo sama-molecule esiphezulu kunesezinsiza zokucubungula i-PVC. Ukwengeza inani elifanele lomlawuli we-PVC foaming ngesikhathi sokucubungula imikhiqizo ye-PVC kungathuthukisa amandla okuncibilika futhi kuvimbele ukubola.
ukwakheka kwamabhamuza. Ngesikhathi esifanayo, kungaba nomphumela omuhle wokwenza ipulasitiki. Inhloso ukuqinisekisa ukuthi ukuncibilika kunoketshezi oluhle.
Izinyathelo zokuphepha zokusebenzisa isilawuli se-PVC foaming:
Uma usebenzisa ama-PVC foam modifier, kubalulekile ukunaka imikhiqizo ye-PVC enamazinga ahlukene e-polymerization bese ukhetha ama-foam modifier ahlukene. Imikhiqizo ye-foam yepulasitiki ifaka amabhodi e-foam, amabhodi amakhulu e-foam, amabhodi amancane e-foam, amabhodi e-foam epulasitiki enkuni, amabhodi e-foam epulasitiki eholayo, njll. Njengoba izithasiselo ze-PVC foam nazo ziyizinto ze-acrylic ezinezakhiwo zokusiza ekucubunguleni, kufanele kuqashelwe ibhalansi yokugcoba yangaphakathi neyangaphandle yefomula lapho uzisebenzisa.
Amaphuzu abalulekile okulawula inqubo yokwenza i-PVC foam:
Ukubumba i-foam yepulasitiki kuhlukaniswe ngezinqubo ezintathu: ukwakheka kwe-bubble core, ukunwetshwa kwe-bubble core, kanye nokuqina komzimba we-foam. Kumashidi e-foam e-PVC anamakhemikhali engeziwe e-foam, ukunwetshwa kwe-bubble nuclei kunomthelela omkhulu kwikhwalithi yeshidi le-foam. I-PVC ingeye-molecule ye-straight chain enamaketanga amafushane e-molecule kanye namandla aphansi okuncibilika. Ngesikhathi senqubo yokwandiswa kwe-bubble core ibe amabhamuza, ukuncibilika akwanele ukumboza amabhamuza, futhi igesi ivame ukugcwala futhi ihlangane namabhamuza amakhulu, kunciphisa ikhwalithi yomkhiqizo wamashidi e-foam.
