Cov yam ntxwv ntawm roj hmab taw
1. Cov roj hmab ncoo: cov khoom siv zoo elastic polymer nrog thim rov qab deformation. Nws yog elastic ntawm chav tsev kub, tuaj yeem tsim qhov loj deformation nyob rau hauv lub zog sab nraud me me, thiab tuaj yeem rov qab mus rau nws lub xeev qub tom qab tshem lub zog sab nraud. Cov roj hmab yog cov tshuaj tsis muaj qhov tshaj kiag ntawm polymer, nws cov iav hloov pauv (T g) yog qhov tsawg, thiab nws lub cev hnyav feem ntau loj, ntau tshaj li ob peb puas txhiab.
2. Cov roj hmab yog cov xim kub-yaj ua thermosetting elastomer, thaum yas yog kub-yaj thiab txias-khoom. Vim tias muaj ntau hom vulcanizates, cov kub thiab txias rau kev txhaj tshuaj thiab kho cov roj hmab nws muaj ntau. Nws kuj tseem yuav muaj kev cuam tshuam los ntawm huab cua hloov thiab huab cua sov sab hauv thiab av noo. Yog li, cov kev ua haujlwm ntawm cov khoom siv roj hmab yuav tsum tau kho kom haum txhua lub sijhawm. Yog tias tsis muaj kev tsim khoom, cov khoom lag luam zoo yuav txawv.
