I-Silicone foam, ekwabizwa ngokuba yi-silicone ebunjiweyo, yimveliso yerabha ene-porous eyenziwe ngerabha ye-silicone njengesiseko semathiriyeli kwaye iveliswa ngamagwebu.

 

　　Ngophuhliso oluqhubekayo kunye nohlaziyo lwetekhnoloji yogwebu, kodwa nangenxa yeempawu zayo eziphezulu, iindawo zokusetyenziswa zibanzi ngakumbi, njengemicu yokutywina, i-cushioning pads, ii-gaskets zokwakha, izinto zokuzahlula zokungcangcazela, izixhobo zokukhusela njalo njalo.

 

Umgaqo we-silicone foam

 

　　Irabha ye-abicah enegwebu, umgaqo kukongeza i-arhente ekhupha ugwebu kwikhompawundi yerabha ye-silicone ekhethiweyo, phantsi koxinzelelo lwemeko yokufudumeza i-vulcanization yerabha ye-silicone igwebu, ukwandiswa kwerabha ukwenza i-sponge-like bubble structure. Izinto eziphambili ezimisela kunye nefuthe kwisakhiwo se-bubble yimali yegesi eyenziwa yi-ejenti yokuvuthela, isantya sokusasazwa kwegesi kwi-rubber, i-viscosity ye-rubber kunye nesantya se-vulcanization. Ukwenza iimveliso ze-silicone ze-foam ezingcono, ukhetho lweentlobo ze-agent egwebu kunye nenkqubo ye-rubber vulcanization ingundoqo.

 

　　Inkqubo yokuvelisa i-Silicone foam

 

　　I-Silicone foam kufuneka ihambe ngoluhlu lweenkqubo zokuvelisa, iteknoloji yokucubungula, ikhonkco ngalinye liya kuba nefuthe kwi-foam ye-silicone egqityiweyo.

 

　　I-1, i-plasticizing (oko kukuthi, iplastiki yokucoca irabha ekrwada. Oko kukuthi, akukho zongezelelo kumatshini wokucokisa ovulekileyo. Vumela irabha ithambe ukuze inyibilike kwi-arhente esebenzisanayo (ukulungiselela ukuxuba).

 

　　Undoqo wokusulungekiswa kweplastiki yerabha ekrwada kukwaphula kunye nokutshabalalisa ikhonkco le-macromolecular yerabha, ukuphucula iplastiki yerabha, kunye nokwenza ukudibanisa kunye nokudibanisa kwekhompawundi kube lula. Kwimveliso yeemveliso zerabha ezinogwebu, irabha ekrwada ifakwe iplastiki ngokupheleleyo, iya kwenza ukuba iplastiki yerabha ibe ngcono, kulula ukwenza umngxuma we-bubble ufanane, ubuninzi obuphantsi, iimveliso ezincinci zokushwabana.

 

I-2, ukuxuba, oko kukuthi, irabha yeplastiki yokongeza iindidi ze-agent (izongezo) zokucoca.

 

Inkqubo yokuxuba iindidi zee-agent kwi-rubber ekrwada (okanye i-raber plasticizing) kwinkqubo yokusabalalisa okufanayo. Njengokuxutywa kwezinye izinto zepolymer, ukwenzela ukuba i-compatibilizer ixutywe ngokufanayo kwirabha eluhlaza, kufuneka isebenzise isenzo esinamandla somatshini wokucoca. Nangona kunjalo, ngenxa yokuba i-compound yerabha inamacandelo amaninzi eejenti ezisebenzisanayo, iimpawu ze-morphological ze-agents ezisebenzisanayo ziyahluka kakhulu, kwaye impembelelo yee-agents ezisebenzisanayo kwinkqubo yokuxuba, i-degree of dispersion, kunye nesakhiwo se-rubber compound nayo inkulu kakhulu. ngoko inkqubo yokuxuba irabha inzima ngakumbi kunezinye izinto zepolymer.

 

Inkqubo yokuxuba inefuthe elibaluleke kakhulu ekusebenzeni kwezinto zerabha. Ukuxuba akulungile, irabha iya kuba yi-dispersion engalinganiyo ye-compatibilizer, iplastiki yerabha iphezulu kakhulu okanye iphantsi kakhulu, ukutshisa, iqabaka kunye nezinye izinto, ezingayi kwenza kuphela i-calendering, ukucinezela, ukubumba kunye nenkqubo ye-vulcanization ayikwazi ukuqhutyelwa. ngaphandle ngokuqhelekileyo, kodwa kukhokelela ekusebenzeni kwemveliso egqityiweyo ukuthotywa, kwaye kunokubangela imveliso yokuphela kobomi. Ngoko ke, ukuxuba enye yeenkqubo ezibalulekileyo kwi-rubber processing.

 

　　3,Ukupaka

 

　　Irabha ekuxutyweni igqityiwe, kufuneka ibekwe ixesha elifanelekileyo, ukwenzela ukuba iintlobo ezahlukeneyo zezongezo ekuxubeni irabha zihlakazwe ngokupheleleyo, izongezo zerabha zisasazwe ngokulinganayo, ukuzinza kobungakanani bemveliso, iqondo lokugudiswa kwerabha. umphezulu, iqondo lokufana kwamaqamza nalo lingcono.

 

　　3,Ubushushu

 

　　Ugwebu lwerabha lunovakalelo kakhulu kubushushu, uhlobo olufanayo lwerabha, isiphumo sogwebu alufani kumaqondo obushushu ahlukeneyo, kuba inkqubo yogwebu kunye nenkqubo ye-vulcanization inovakalelo kubushushu bamaqondo ahlukeneyo, inkqubo iyatshintsha, idigri ehambelanayo yomahluko, isiphumo nayo yahlukile.

 

　　4, ukubumba

 

　　Iimveliso zerabha ezinogwebu ezilandelwayo kunye neendlela zokubumba kukubumba, ukubumba, ukubumba ipleyiti, njl.njl., ngokuhambelana nesakhiwo esifunekayo semveliso egqityiweyo, iinkcukacha, ubude, ubungakanani, imilo, ubulukhuni, umbala wahlukile, kunye nokhethekileyo. Iimfuno zemizobo, unokwenza ulungelelwaniso olungelulo oluqhelekileyo.
