Lub hauv paus roj hmab, ntub dej ntuj los yog hluavtaws, yuav tsum muaj kev sib xyaw nrog ntau cov tshuaj sib txawv / cov khoom siv los muab cov roj hmab sib txuas uas tuaj yeem ua tiav thiab ua rau cov khoom tiav.
Ib daim ntawv qhia rau kev ua cov roj hmab sib xyaw suav nrog, tshwj tsis yog cov roj hmab, kwv yees li 10 -15 ntau yam tshuaj lom neeg. Cov tshuaj sib txawv tau muab faib ua pawg, nyob ntawm lawv txoj haujlwm, thiab ib qho ntawm cov tshuaj lom neeg tseem ceeb tshaj plaws yog cov tshuaj tiv thaiv vulcanization uas hla cov roj hmab molecules rau hauv peb qhov ntev, muab cov roj hmab nws cov yam ntxwv tshwj xeeb.
