Kugona kwerabha kushatisa pasi pemasimba ekunze uye kuchengetedza deformation yayo kunyange mushure mekunge masimba ekunze abviswa anonzi plasticity. Nzira yekuwedzera plastiki yerabha inonzi plasticization. Rubber ine plasticity kuitira kuti isanganise zvakaenzana nemhando dzakasiyana-siyana dzekuwedzera panguva yekusanganiswa; Zviri nyore kupinda mumachira emucheka panguva yekutenderedza kugadzirisa; Iine fluidity yakanaka panguva yeextrusion uye jekiseni. Mukuwedzera, kuumba kunogonawo kugadzira zvimiro zveyunifomu yerubha, zvichiita kuti zvive nyore kudzora maitiro ekugadzira. Nekudaro, shanduko yekuumba inogona kuderedza simba, elasticity, kupfeka kuramba uye zvimwe zvimiro zverabha ine vulcanized, saka basa rekuumba rinoda kunyatso kudzora.
Izvo zvinodikanwa zvepurasitiki zverabha mbishi zvakakodzera, uye ingave yakakura kana diki zvakanyanya inogona kuve nemhedzisiro yakaipa. Yakawandisa plastiki yerabha yakasvibirira inogona kuderedza iyo yemuviri uye yemagetsi zvimiro zve vulcanized rabha, zvichikanganisa kushandiswa kwechigadzirwa. Kana iyo plastiki yerabha yakasvibiswa yakanyanya kuderera, inokonzera matambudziko mukugadzirisa uye kuita kuti zvive zvakaoma kuti rubber rubber rusanganiswe zvakaenzana; Kukunguruka, pamusoro peiyo semi-yakapedza chigadzirwa haina kutsetseka kana uchidzvanya kunze; Yakakura shrinkage chirango chinoita kuti zviome kubata saizi yehafu-yapedzwa zvigadzirwa; Panguva yekukunguruka, zvakaoma kuti tepi yekunamatira ikwidze mumucheka, zvichiita kuti peeling yemucheka wakarembera wetambo wetambo uye kuderedza zvakanyanya kubatanidzwa pakati pezvinyorwa zvezvinhu. Kana iyo plastiki isina kuenzana, inogonawo kukonzera kusagadzikana mune tekinoroji uye yemuviri mechanical zvinhu zvekunamatira.
Naizvozvo, tekinoroji yekugadzira rabha ine zvimwe zvinodikanwa zvepurasitiki yerabha raw. Kazhinji kutaura, zvinonamira zvinoshandiswa kupfekedza, kunyura, kukwesha, uye kugadzira zvinonamira zvesiponji zvinoda purasitiki yakakwira; Zvigadzirwa zverabha uye zvinhu zvekuumba zvinoda yakakwirira yemuviri uye michina zvivakwa uye kuomarara kwakanaka kwehafu-yapedzwa zvigadzirwa zvinofanirwa kuve nepurasitiki yakaderera; Iyo yepurasitiki yekunamatira yakawedzera iri pakati pezviviri.
