1. Rubber pads: Cov ntaub ntawv zoo heev ntawm cov ntaub ntawv polymer nrog rov qab deformation. Lawv yog elastic nyob rau hauv chav tsev kub, muaj peev xwm deformation tseem ceeb nyob rau hauv me me sab nraud quab yuam, thiab rov qab mus rau lawv cov qub zoo tom qab lub zog raug tshem tawm. Roj hmab yog ib qho amorphous polymer tag nrho nrog lub iav hloov pauv kub (Tg) thiab qhov hnyav molecular siab heev, feem ntau tshaj li pua pua txhiab.
2. Roj hmab yog cov thermosetting elastomer, thaum cov yas yog thermosetting thiab cryogenic. Vim qhov sib txawv ntawm cov vulcanizates tseem ceeb, molding thiab curing kub ntawm cov roj hmab sib txawv heev thiab tuaj yeem cuam tshuam los ntawm kev hloov pauv huab cua thiab sab hauv tsev kub thiab av noo. Yog li ntawd, cov khoom siv rau cov khoom siv roj hmab yuav tsum tau hloov kho kom haum txhua lub sijhawm; txwv tsis pub, kev hloov pauv ntawm cov khoom zoo yuav tshwm sim.
3. Technical tsis: -100℃~ 300 degree, Siab<3.0MPa, DN15～DN400
