Yini okufanele uyenze uma ikhwalithi ye-PVC Foam regulators impofu?

Phakathi nenqubo yokwenza amagwebu, igesi eboliswe i-ejenti egwebulile yenza ama-bubbles ekuncibilikeni. Kunomkhuba wamabhamuza amancane anwebeka abheke kumabhamuza amakhulu kulawa mabhamuza. Ubukhulu nobuningi bamabhamuza abuhlobene nje kuphela nenani le-ejenti enegwebu engeziwe, kodwa futhi namandla okuncibilika kwe-polymer. Uma ukuqina kuphansi kakhulu, igesi ingaphunyuka kalula lapho isakazwa phezu kokuncibilika, futhi amabhamuza amancane ahlangane namanye akhe amabhamuza amakhulu. Amaketanga amade we-molecular of regulators amagwebu abanjwe futhi anamathele emaketangeni e-PVC, akha isakhiwo esithile senethiwekhi. Ngakolunye uhlangothi, ikhuthaza i-plasticization yezinto ezibonakalayo, futhi ngakolunye uhlangothi, ithuthukisa amandla okuncibilika kwe-PVC, ukuze udonga lwamangqamuzana e-foam lukwazi ukumelana nokucindezela kwegesi ngaphakathi kweseli le-foam ngesikhathi senqubo yokugwaza, ukuze lingaqhekeki. ngenxa yamandla anganele. Izilawuli ze-Foam zingenza ama-pores omkhiqizo abe mancane futhi abe maningi, ngesakhiwo se-pore esifanayo futhi esinengqondo, ukunciphisa kakhulu ukuminyana komzimba wegwebu. Ikhwalithi ephansi noma isilinganiso esinganele sezilawuli ezikhihliza amagwebu singaholela emandleni aphansi egwebu, okuholela ekuqhumeni noma amabhamuza ezintambo.

Isisindo samangqamuzana kanye ne-viscosity yezilawuli ezinegwebu ezikhiqizwa abakhiqizi abahlukene ziyahlukahluka kakhulu. Lapho imikhiqizo enegwebu iphuka noma amabhamuza ezintambo, nezinye izindlela zingasebenzi, ukufaka isilawuli esikhihliza amagwebu noma ukwandisa umthamo ngokufanele ngokuvamile kungaveza imiphumela ebalulekile. Kodwa-ke, ukungeza noma ukushintsha izilawuli ezikhihliza amagwebu ngezisindo zamangqamuzana eziphezulu kungakhuphula ukuminyana komkhiqizo ngenxa ye-viscosity eyeqile, okuvimbela ukunwetshwa kwamabhamuza ekuncibilikeni. Futhi ngenxa ye-viscosity ephezulu yokuncibilika, i-fluidity izowohloka, okuholela ekukhishweni okungalingani kwesikhunta, okuthinta ukuthambeka kwendawo yepuleti, ngisho nesikhathi esifushane sokukhiqiza, okuholela ekuhlulekeni kokunamathisela isikhunta, ikakhulukazi lapho kukhiqizwa amapuleti anogqinsi. ngaphansi kuka-10 mm.
