Lub peev xwm ntawm roj hmab kom deform nyob rau hauv sab nraud quab yuam thiab tswj nws deformation txawm tias tom qab sab nraud quab yuam raug tshem tawm hu ua plasticity. Cov txheej txheem ntawm kev nce lub plasticity ntawm roj hmab hu ua plasticization. Roj hmab muaj plasticity kom sib tov sib npaug nrog ntau yam additives thaum lub sij hawm sib tov; Yooj yim nkag mus rau hauv cov ntaub textile thaum lub sij hawm dov ua; Nws muaj zoo fluidity thaum lub sij hawm extrusion thiab txhaj tshuaj. Tsis tas li ntawd, molding kuj tuaj yeem ua rau cov khoom ntawm roj hmab sib xws, ua rau nws yooj yim los tswj cov txheej txheem ntau lawm. Txawm li cas los xij, kev hloov pauv molding tuaj yeem txo qhov muaj zog, elasticity, hnav tsis kam thiab lwm yam khoom ntawm roj hmab vulcanized, yog li kev ua haujlwm molding yuav tsum tau tswj hwm nruj me ntsis.
Qhov xav tau ntawm cov roj hmab nyoos yog qhov tsim nyog, thiab loj dhau lossis me dhau tuaj yeem muaj cov teebmeem tsis zoo. Qhov ntau dhau ntawm cov roj hmab nyoos tuaj yeem txo cov khoom siv lub cev thiab cov khoom siv kho tshuab ntawm cov roj hmab vulcanized, cuam tshuam rau kev siv cov khoom. Yog tias qhov plasticity ntawm cov roj hmab nyoos qis dhau, nws yuav ua rau muaj teeb meem hauv kev ua thiab ua rau nws nyuaj rau cov khoom siv roj hmab sib xyaw kom sib npaug; dov, qhov chaw ntawm cov khoom tiav ib nrab tsis du thaum nias tawm; Kev nplua loj ua rau nws nyuaj rau nkag siab qhov loj ntawm cov khoom tiav ib nrab; Thaum dov, nws nyuaj rau daim kab xev nplaum txhuam rau hauv cov ntaub, ua rau cov ntaub nplaum dai tev tawm thiab txo qhov kev nplaum ntawm cov txheej khoom. Yog tias qhov plasticity tsis sib xws, nws kuj tseem tuaj yeem ua rau tsis sib xws hauv cov khoom siv thev naus laus zis thiab lub cev ntawm cov nplaum.
Yog li ntawd, cov txheej txheem ua roj hmab muaj qee qhov yuav tsum tau ua rau cov roj hmab nyoos plasticity. Feem ntau hais lus, cov nplaum siv rau txheej, dipping, scraping, thiab tsim cov nplaum daim txhuam cev xav tau plasticity siab; Cov ntaub ntawv roj hmab thiab cov ntaub ntawv molding uas xav tau cov khoom siv lub cev thiab cov khoom siv kho tshuab siab thiab kev tawv zoo ntawm cov khoom tiav ib nrab yuav tsum muaj plasticity qis; Qhov plasticity ntawm cov nplaum extruded yog nyob nruab nrab ntawm ob.
