Igwebu le-silicone, elaziwa nangokuthi i-silicone ebunjiwe, iwumkhiqizo wesakhiwo senjoloba enezimbotshana owenziwe ngerabha ye-silicone njengento eyisisekelo futhi ekhiqizwa ngokugwaza.

 

　　Ngokuthuthuka okuqhubekayo nokuvuselelwa kobuchwepheshe obugwebu, kodwa futhi ngenxa yezimpawu zayo eziphakeme, izindawo zokufaka izicelo ziningi kakhulu, njengemicu yokuvala, ama-cushioning pads, ama-gaskets wokwakha, izinto zokuhlukanisa i-vibration, imishini yokuzivikela nokunye.

 

Isimiso se-silicone foam

 

　　Irabha ye-silicone enegwebu, isimiso siwukwengeza i-ejenti ekhihliza amagwebu esakhiweni serabha yerabha ekhethiwe, ngaphansi kwengcindezi yesimo sokushisisa igwebu lerabha le-silicone le-vulcanization, ukunwetshwa kwenjoloba ukuze kwakhiwe isakhiwo sebhamuza esinjengesipontshi. Izici eziyinhloko ezinquma futhi zibe nomthelela ekubunjweni kwebhamuza inani legesi elikhiqizwa i-ejenti evuthelayo, isivinini sokusabalalisa kwegesi enjoloba, i-viscosity yerabha kanye nesivinini se-vulcanization. Ukwenza imikhiqizo engcono ye-silicone yegwebu, ukukhetha kwezinhlobo ze-ejenti enegwebu nohlelo lwe-rubber vulcanization kuyisihluthulelo.

 

　　Inqubo yokukhiqiza igwebu le-Silicone

 

　　I-Silicone Foam idinga ukudlula uchungechunge lwezinqubo zokukhiqiza, ubuchwepheshe bokucubungula, isixhumanisi ngasinye sizoba nomthelela ku-foam ye-silicone eqediwe.

 

　　1, ukwenza ipulasitiki (okungukuthi, ipulasitiki yokucwengwa kwenjoloba eluhlaza. Okusho ukuthi, azikho izithasiselo emshinini wokucwenga ovulekile. Vumela irabha ithambe ukuze incibilike ku-ejenti esebenzisanayo (ukulungiselela ukuxuba).

 

　　Ingqikithi yokucwengwa kwepulasitiki yenjoloba eluhlaza ukuphula nokucekela phansi iketango elikhulu lenjoloba, kuthuthukiswe ipulasitiki yenjoloba, nokwenza ukuxutshwa nokuxutshwa kwenhlanganisela kube lula. Ekukhiqizeni imikhiqizo yenjoloba enegwebu, irabha eluhlaza ifakwe ipulasitiki ngokugcwele, izokwenza ipulasitiki yenjoloba ibe ngcono, kube lula ukwenza ukufana kwembobo ye-bubble, ukuminyana okuphansi, imikhiqizo emincane yokuncipha.

 

2, ukuxuba, okungukuthi, irabha plasticized ukwengeza ezihlukahlukene ejenti (izithasiselo) yokucwengisiswa.

 

Inqubo yokuxuba iyinhlobonhlobo yama-ejenti enjoloba eluhlaza (noma irabha ye-plasticizing) ekuhlakazweni komfaniswano. Njengokuxutshwa kwezinye izinto ze-polymer, ukuze wenze i-compatibilizer ihlanganiswe ngokulinganayo ku-rubber eluhlaza, kufanele isebenzise isenzo esinamandla somshini womshini wokucwenga. Kodwa-ke, ngenxa yokuthi i-compound yenjoloba inezingxenye eziningi zama-agent asebenzisanayo, izakhiwo ze-morphological zama-ejenti abambisanayo ziyahlukahluka kakhulu, futhi ithonya lama-agent asebenzisanayo enqubweni yokuxuba, izinga lokuhlakazeka, kanye nesakhiwo se-compound yenjoloba nakho kukhulu kakhulu, ngakho-ke inqubo yokuxuba irabha iyinkimbinkimbi kakhulu kunezinye izinto ze-polymer.

 

Inqubo yokuxuba inomphumela obaluleke kakhulu ekusebenzeni kwezinto zenjoloba. Ukuxuba akulungile, irabha izohlakazeka ngokungalingani kwe-compatibilizer, ipulasitiki yenjoloba iphezulu kakhulu noma iphansi kakhulu, ivutha, isithwathwa nezinye izenzakalo, ezingeke zenze inqubo ye-calendering, ukucindezela, ukubumba kanye ne-vulcanization ayikwazi ukuqhutshwa kuphela. ukuphuma ngokujwayelekile, kodwa futhi kuholele ekusebenzeni komkhiqizo oqediwe ukuwohloka, futhi kungase kubangele ngisho nomkhiqizo wokuphela kokuqala kokuphila. Ngakho-ke, ukuxuba kungenye yezinqubo ezibalulekile ekusetshenzisweni kwenjoloba.

 

　　3,Ukupaka

 

　　Injoloba ekuxubeni isiqediwe, kufanele ibekwe isikhathi esifanele, ukuze izinhlobonhlobo zezithasiselo ekuxubeni kwerabha zihlakazwe ngokugcwele, izengezo zenjoloba zihlakazwe ngokulinganayo, ukuzinza kosayizi womkhiqizo, izinga lokushelela kwerabha. ebusweni, izinga lokufana kwamabhamuza nalo lingcono.

 

　　3,Izinga lokushisa

 

　　Igwebu lenjoloba lizwela kakhulu ekushiseni, uhlobo olufanayo lwenjoloba, umphumela ogwebuzelayo awufani emazingeni okushisa ahlukene, ngoba uhlelo olunamagwebu kanye nesistimu ye-vulcanization luyazwela ekushiseni kwamadigri ahlukene, uhlelo luyashintsha, izinga elihambisanayo lomehluko, umphumela nawo uhlukile.

 

　　4, ukubumba

 

　　Imikhiqizo yenjoloba enegwebu elandelwa izindlela zokucutshungulwa kanye nezindlela zokubumba i-extrusion yokubunjwa, ukubumba, ukubunjwa kwepuleti, njll., ngokuya ngesakhiwo esidingekayo somkhiqizo oqediwe, imininingwane, ubude, usayizi, ukuma, ubulukhuni, umbala wehlukile, kanye nesakhiwo esikhethekile. izidingo zemidwebo, ungakwazi ukwenza ngokwezifiso okungeyona okujwayelekile komuntu siqu.
