Umlawuli we-foam okhiqizwe yi-Bontecn Group China uthinta ngqo ukwakheka, ukuzinza, kanye nesakhiwo sokugcina sama-foam pores ngokulawula izakhiwo ze-polymer melts. Izimpawu ezithile yilezi ezilandelayo:
1. Ukufana kanye nokucwengisiswa kwama-foam pores
Thuthukisa amandla nokunwebeka kokuncibilika, khuthaza ukusatshalaliswa okufanayo kwegesi ekuncibilikeni kwe-PVC, yakha ama-micropores azimele (ububanzi obungu-0.1-0.5mm), futhi unciphise inkinga yokuhlangana kwama-bubble noma ukugoqana. Ngesikhathi esifanayo, lungisa ukuhlangana kokuncibilika ukuqinisekisa ukuthi izindonga zeseli zingamelana nokucindezela kwegesi futhi zigcine ukuqina kwesakhiwo seseli esivaliwe.
2. Ubuningi bamaseli nokulawula usayizi
Umthamo udinga ukuhambisana ngokunembile: uphansi kakhulu (<4phr) uholela ekunganele kwamandla okuncibilika, okubangela ukuqhekeka kwamabhamuza noma ukuwa kobuso; Uma kuphezulu kakhulu (>8phr), kuzoqinisa kakhulu ukuncibilika, kucindezele ukwanda kwamabhamuza, futhi esikhundleni salokho kukhulise ubuningi bomkhiqizo. Uma isisindo sama-molecule siphezulu (njengemodeli engu-530), kulapho ama-pores eba mancane futhi kwehlisa ubuningi, kodwa kuyazwela ekushiseni kokucubungula.
3. Ukuvimbela amaphutha kanye nokwenza ngcono isakhiwo
Ukuze kuvinjelwe amabhamuza angajwayelekile (njengamabhamuza amade noma amehlo enhlanzi), kuyadingeka ukuhlanganisa uhlelo lokugcoba kanye nokushisa kwenqubo: ukushelela kwangaphandle ngokweqile kuzonciphisa ingcindezi yokuncibilika futhi kubangele ukungalingani kobuningi bendawo; Ukushintshashintsha kwezinga lokushisa kuka-± 5 ℃ kungaphazamisa ukufana kwama-pores futhi kudinge ukungezwa kwama-modifiers njenge-zinc stearate ukuze kulinganiswe.
4. Ukuzivumelanisa nezimo okuguquguqukayo
Ukukhethwa kwemodeli (njenge-KF-100) yezinhlobo ezahlukene zemikhiqizo (njengezindwangu ze-PVC eziqinile noma izinto zezicathulo ezithambile) kuthinta ngqo isakhiwo sembobo: emikhiqizweni ethambile, kudingeka umlawuli okhethekile ukuze kugwenywe ukuqhakaza kwesikhumba futhi kuthuthukiswe ukuqina kokuthinta.
