Extruded silicone rabha chinhu chakakosha mumhando yerabha. Nekudaro, kana ikasabatwa nemazvo, mabhubhu anoumba muchigadzirwa panguva yepombi extrusion processing.
Chimwe chezvikonzero zvikuru zvekuumbwa kwemabhuru ndechekuti precipitated silica inoshandiswa seinosimbisa kuzadza. Iine mvura yakawanda (5% kusvika 8%) pachayo, iyo yakaoma kubvisa zvachose panguva yekugadzirwa. Uyezve, mushure mokuitwa musanganiswa werabha, inowanzotora mvura. Chechipiri ndechekuti mweya wakanyorova unopinzwa mukomboni yerabha panguva ye-kusanganisazve. Nyaya yechitatu ndeyokuti mhepo yakaunzwa nekomboni yerubha panguva yeextrusion process haina kukurumidza kuburitswa.
Kugadzirisa dambudziko rebubble re extruded pombi rabha (kunyanya inowanzoitika munguva yechando), matanho akawanda anoda kutorwa, sekushandisa mamwe akakosha magadzirirwo ekudzora maajenti kuti vakwanise kuita zvirinani nemapoka ehydroxyl musilica. Panguva imwe cheteyo, simbisa kusanganisa kwemukati uye edza kubvisa mvura nezvinhu zvakaderera-zvemamorekuru kubva mukomboni yerabha nepaunogona napo. Kuwedzera zvakafanira kukosha kwepurasitiki yekomboni yerubha kuti iite kuti iite zvirinani kudzinga mabhuru emhepo panguva yekugadzira.
