I-foam ye-silicone, eyaziwa nangokuthi i-silicone ebunjiwe, iwumkhiqizo wesakhiwo senjoloba onezimbobo owenziwe ngerabha ye-silicone njengezinto eziyisisekelo futhi okhiqizwa ngokufaka igwebu.

 

　　Ngokuthuthukiswa okuqhubekayo nokuvuselelwa kobuchwepheshe bokugqwala, kodwa futhi ngenxa yezici zabo eziphakeme, izindawo zokusetshenziswa zibanzi kakhulu, njengezicucu zokuvala, ama-cushioning pads, ama-gasket okwakha, izinto zokuhlukanisa ukudlidliza, imishini yokuzivikela njalo njalo.

 

Isimiso se-silicone foam

 

　　Irabha ye-silicone enegwebu, umgomo ukwengeza i-ejenti yegwebu ku-compound yerabha ye-silicone ekhethiwe, ngaphansi kwengcindezi yesimo sokushisa i-vulcanization i-silicone rubber foam, ukunwetshwa kwerabha ukuze kwakhiwe isakhiwo sebhamuza esifana nesiponji. Izici eziyinhloko ezinquma futhi zithonye isakhiwo sebhamuza inani legesi elikhiqizwa yi-ejenti evuthelayo, ijubane lokusabalalisa kwegesi erabha, i-viscosity yerabha kanye nesivinini se-vulcanization. Ukuze kwenziwe imikhiqizo ye-foam ye-silicone engcono, ukukhetha izinhlobo ze-ejenti yegwebu kanye nohlelo lwe-vulcanization yerabha kuyisihluthulelo.

 

　　Inqubo yokukhiqiza i-silicone foam

 

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

 

　　1, ukwenza ipulasitiki (okungukuthi, upulasitiki wokucwenga irabha eluhlaza. Okungukuthi, azikho izithasiselo ekucwengisisweni komshini ovulekile. Vumela irabha ithambe ukuze incibilike ibe yinto ebambisanayo (ukulungiselela ukuxuba).

 

　　Ingqikithi yokucwengisiswa kwepulasitiki kwerabha eluhlaza ukuphula nokubhubhisa uchungechunge lwerabha olune-macromolecule, ukuthuthukisa i-plasticity yerabha, nokwenza ukuxuba nokuxubana kwenhlanganisela kube lula. Ekukhiqizweni kwemikhiqizo yerabha ene-foam, irabha eluhlaza ifakwa ipulasitiki ngokugcwele, izokwenza i-plasticity yerabha ibe ngcono, kube lula ukwenza ukufana kwembobo yebhamuza, ukuminyana okuphansi, kanye nemikhiqizo emincane yokuncipha.

 

2, ukuxuba, okungukuthi, irabha eyenziwe ngepulasitiki ukuze kufakwe izinto ezahlukahlukene (izithasiselo) zokucwengisisa.

 

Inqubo yokuxuba iyizinhlobo ezahlukene zama-ejenti enjolobeni eluhlaza (noma irabha epulasitiki) enkambisweni yokuhlakazeka okufanayo. Njengoba kunjalo ngokuxuba ezinye izinto ze-polymer, ukuze i-compatibilizer ihlanganiswe ngokulinganayo enjolobeni eluhlaza, kumele kusetshenziswe isenzo esinamandla somshini wokuhlanza. Kodwa-ke, ngenxa yokuthi i-compound yerabha inezingxenye eziningi zama-ejenti asebenzisanayo, izakhiwo ze-morphological zama-ejenti asebenzisanayo ziyahlukahluka kakhulu, futhi ithonya lama-ejenti asebenzisanayo enkambisweni yokuxuba, izinga lokuhlakazeka, kanye nesakhiwo se-compound yerabha nakho kukhulu kakhulu, ngakho-ke inqubo yokuxuba yerabha iyinkimbinkimbi kakhulu kuneyezinye izinto ze-polymer.

 

Inqubo yokuxuba inomphumela obaluleke kakhulu ekusebenzeni kwezinto zerabha. Ukuxuba akukuhle, irabha izosakazwa ngokungalingani kwe-compatibilizer, i-plasticity yerabha iphakeme kakhulu noma iphansi kakhulu, ukusha, iqhwa nezinye izinto, okungeke nje kwenze inqubo yokuhlanganisa, ukucindezela, ukubumba kanye ne-vulcanization ingenzeki ngendlela evamile, kodwa futhi kuholele ekusebenzeni komkhiqizo oqediwe ukuwohloka, futhi kungabangela ngisho nomkhiqizo wokuphela kokuphila. Ngakho-ke, ukuxuba kungenye yezinqubo ezibalulekile ekucubungulweni kwerabha.

 

　　3、Ukupaka

 

　　Irabha ekuxubeni isiqediwe, kumele ibekwe isikhathi esifanele, ukuze izithasiselo ezahlukahlukene ekuxubeni irabha zihlakazeke ngokuphelele, izithasiselo zerabha zihlakazeke ngokulinganayo, ukuzinza kosayizi womkhiqizo, izinga lokushelela kobuso, izinga lokufana kwamabhamuza nakho kube ngcono.

 

　　3、Izinga lokushisa

 

　　I-foam yerabha iyazwela kakhulu ekushiseni, uhlobo olufanayo lwerabha, umphumela wokugqwala awufani emazingeni okushisa ahlukene, ngoba uhlelo lokugqwala kanye nohlelo lokuvunguza luyazwela ekushiseni kwamadigri ahlukene, uhlelo luyashintsha, izinga lomehluko ofanayo, umphumela nawo uhlukile.

 

　　4, ukubumba

 

　　Imikhiqizo yerabha ene-foam yokucubungula okulandelayo kanye nezindlela zokubumba ziyi-extrusion molding, molding, plate molding, njll., ngokuhambisana nesakhiwo esidingekayo somkhiqizo oqediwe, imininingwane, ubude, usayizi, ukuma, ubulukhuni, umbala uhlukile, kanye nezidingo ezikhethekile zemidwebo, ungenza ngokwezifiso ezingezona ezejwayelekile ezenziwe ngezifiso.
