I-silicone foam, ekwaziwa ngokuba yi-molded silicone, yimveliso yesakhiwo serabha enemingxuma eyenziwe ngerabha ye-silicone njengesixhobo esisisiseko kwaye iveliswa ngokufutha.

 

　　Ngophuhliso oluqhubekayo kunye nokuhlaziywa kwetekhnoloji yokufutha amagwebu, kodwa nangenxa yeempawu zayo ezigqwesileyo, iindawo zokusetyenziswa zibanzi ngakumbi nangakumbi, ezifana nemicu yokutywina, ii-cushioning pads, ii-gasket zokwakha, izixhobo zokwahlukanisa ukungcangcazela, izixhobo zokukhusela njalo njalo.

 

Umgaqo we-silicone foam

 

　　Irabha ye-silicone ekhupha igwebu, umgaqo kukongeza i-agent ekhupha igwebu kwi-compound yerabha ye-silicone ekhethiweyo, phantsi koxinzelelo lwe-state heating vulcanization silicone rubber foam, ukwandiswa kwerabha ukwenza isakhiwo se-bubble esifana nesiponji. Izinto eziphambili ezimisela kwaye zichaphazela ulwakhiwo lwe-bubble bubungakanani begesi eveliswa yi-agent evuthelayo, isantya sokusasazwa kwegesi kwirabha, i-viscosity yerabha kunye nesantya se-vulcanization. Ukwenza iimveliso ze-foam ye-silicone ezingcono, ukukhethwa kweentlobo ze-agent ekhupha igwebu kunye nenkqubo ye-vulcanization yerabha yeyona nto ibalulekileyo.

 

　　Inkqubo yokuvelisa i-silicone foam

 

　　Ifoam yesilicone kufuneka idlule kuthotho lweenkqubo zemveliso, iteknoloji yokucubungula, ikhonkco ngalinye liya kuba nefuthe kwifoam yesilicone egqityiweyo.

 

　　1, ukwenza iplastiki (oko kukuthi, iplastiki yokucocwa kwerabha eluhlaza. Oko kukuthi, akukho zongezo kumatshini wokucocwa ovulekileyo. Vumela irabha ithambe ukuze inyibilike ibe yiarhente esebenzisana nayo (ukulungiselela ukuxuba).

 

　　Eyona nto iphambili ekucocweni kweplastiki yerabha eluhlaza kukuqhekeza nokutshabalalisa uthotho lwerabha oluyi-macromolecular, ukuphucula i-plasticity yerabha, nokwenza kube lula ukuxuba nokudibanisa i-compound. Kwimveliso yeemveliso zerabha ezine-foam, irabha eluhlaza yenziwe ngeplastiki ngokupheleleyo, iya kwenza i-plasticity yerabha ibe ngcono, kube lula ukwenza i-bubble hole ifane, i-low density, kunye neemveliso ezincinci zokuncitshiswa.

 

2, ukuxuba, oko kukuthi, irabha eyenziwe ngeplastiki ukongeza iintlobo ngeentlobo zezinto ezisetyenziselwa ukucocwa.

 

Inkqubo yokuxuba ziintlobo ngeentlobo zeearhente kwirabha eluhlaza (okanye irabha yokwenza iplastiki) kwinkqubo yokusasazwa okufanayo. Njengakwindlela yokuxuba ezinye izinto zepolymer, ukuze i-compatibilizer ixutywe ngokulinganayo kwirabha eluhlaza, kufuneka kusetyenziswe isenzo esinamandla somatshini wokucoca. Nangona kunjalo, ngenxa yokuba i-compound yerabha inamacandelo amaninzi eearhente ezisebenzisanayo, iipropati ze-morphological zeearhente ezisebenzisanayo zahluka kakhulu, kwaye impembelelo yeearhente ezisebenzisanayo kwinkqubo yokuxuba, ubungakanani bokusasazwa, kunye nolwakhiwo lwe-compound yerabha nayo inkulu kakhulu, ngoko ke inkqubo yokuxuba irabha iyinkimbinkimbi ngakumbi kunezinye izinto zepolymer.

 

Inkqubo yokuxuba inefuthe elibaluleke kakhulu ekusebenzeni kwezinto zerabha. Ukuxuba akulunganga, irabha iya kuba nokusasazwa okungalinganiyo kwe-compatibilizer, i-plasticity yerabha iphezulu kakhulu okanye iphantsi kakhulu, ukutsha, iqabaka kunye nezinye izinto, eziya kwenza ukuba inkqubo yokudibanisa, ukucinezela, ukubumba kunye ne-vulcanization ingenzeki ngendlela eqhelekileyo, kodwa ikwakhokelela ekuwohlokeni kwemveliso egqityiweyo, kwaye inokubangela nokuba imveliso iphele kwangoko. Ke ngoko, ukuxuba yenye yeenkqubo ezibalulekileyo ekucutshungulweni kwerabha.

 

　　3、Indawo yokupaka

 

　　Irabha ekuxubeni igqityiwe, kufuneka ibekwe ixesha elifanelekileyo, ukuze iintlobo ngeentlobo zezongezo ekuxubeni irabha zisasazeke ngokupheleleyo, izongezo zerabha zisasazeke ngokulinganayo, uzinzo lobungakanani bemveliso, inqanaba lokuguda komphezulu, inqanaba lokufana kwamaqamza nako kube ngcono.

 

　　3、Ubushushu

 

　　I-foam yerabha inovakalelo olukhulu kubushushu, uhlobo olufanayo lwerabha, isiphumo sokugqwala asifani kubushushu obahlukeneyo, kuba inkqubo yokugqwala kunye nenkqubo yokugquma ivakalelwa kubushushu obuhlukeneyo, inkqubo iyatshintsha, inqanaba lomahluko ofanayo, isiphumo sahlukile.

 

　　4, ukubumba

 

　　Iimveliso zerabha ezinefoam, iindlela ezilandelayo zokucutshungulwa kunye nokubumba ziindlela zokukhupha ulwelo, ukubumba, ukubumba ipleyiti, njl.njl., ngokuhambelana nesakhiwo esifunekayo semveliso egqityiweyo, iinkcukacha, ubude, ubungakanani, imilo, ubulukhuni, umbala wahlukile, kunye neemfuno ezizodwa zemizobo, ungenza ulwenziwo olungelulo oluqhelekileyo.
