Lub peev xwm ntawm cov roj hmab kom deform nyob rau hauv cov rog sab nraud thiab tswj nws cov deformation txawm tias tom qab lub zog sab nraud raug tshem tawm yog hu ua plasticity. Cov txheej txheem ntawm kev nce cov yas ntawm cov roj hmab yog hu ua plasticization. Roj hmab muaj plasticity thiaj li sib tov sib npaug nrog ntau yam additives thaum sib tov; Yooj yim rau nkag mus rau hauv cov ntaub ntawv textile thaum dov ua; Nws muaj fluidity zoo thaum extrusion thiab txhaj tshuaj. Tsis tas li ntawd, molding tuaj yeem ua rau cov khoom ntawm cov roj hmab sib xws, ua kom yooj yim los tswj cov txheej txheem ntau lawm. Txawm li cas los xij, kev hloov molding tuaj yeem txo lub zog, elasticity, hnav tsis kam thiab lwm yam khoom ntawm cov roj hmab vulcanized, yog li kev lag luam molding yuav tsum tau tswj nruj me ntsis.
Qhov kev xav tau ntawm plasticity ntawm cov roj hmab nyoos yog qhov tsim nyog, thiab loj dhau los yog me me tuaj yeem muaj qhov tsis zoo. Cov yas ntau dhau ntawm cov roj hmab nyoos tuaj yeem txo lub cev thiab cov khoom siv ntawm cov roj hmab vulcanized, cuam tshuam rau kev siv ntawm cov khoom. Yog hais tias cov yas ntawm cov roj hmab nyoos tsawg dhau lawm, nws yuav ua rau muaj teeb meem hauv kev ua haujlwm thiab ua rau nws nyuaj rau cov khoom siv roj hmab sib tov sib xyaw; Rolling, nto ntawm cov khoom semi-tiav tsis du thaum nias tawm; Loj shrinkage nplua ua rau nws nyuaj rau tuav qhov loj ntawm cov khoom semi-tiav lawm; Thaum lub sij hawm dov, nws yog ib qho nyuaj rau cov nplaum nplaum rau hauv cov ntaub, ua rau tev tawm ntawm cov hlua khi hlua khi thiab txo cov adhesion ntawm cov khoom txheej. Yog hais tias lub plasticity tsis sib npaug, nws kuj tuaj yeem ua rau tsis sib xws hauv cov cuab yeej technology thiab lub cev ntawm cov nplaum.
Yog li ntawd, cov roj hmab ua tshuab muaj qee yam yuav tsum tau ua rau plasticity ntawm raw roj hmab. Feem ntau hais lus, adhesives siv rau txheej, dipping, scraping, thiab manufacturing sponge adhesives yuav tsum tau siab plasticity; Cov khoom siv roj hmab thiab cov khoom siv molding uas yuav tsum muaj lub cev thiab cov khoom siv zoo thiab cov khoom tawv tawv zoo yuav tsum muaj cov yas qis; Lub plasticity ntawm extruded nplaum yog nruab nrab ntawm ob.
