Cov kev xav tau ntawm kev ua haujlwm:
(1) Nws tuaj yeem siv rau lub sijhawm ntev nyob rau hauv qhov xwm txheej ntawm 150 degree, thiab tuaj yeem siv rau lub sijhawm luv luv nyob rau hauv cov xwm txheej siab dua 150 degree.
(2) Tsis tsuas yog nws yuav tsum muaj kev hnav zoo ntawm chav tsev kub, tab sis kuj yuav tsum tsis txhob deteriorate ntawm qhov kub thiab txias.
(3) Ua ntej vulcanization, yuav tsum muaj qee qhov nws tus kheej viscosity thiab kev sib nrig sib viscosity nrog tsis nplaum, thiab tom qab vulcanization, muaj lub siab nplaum nplaum.
(4) Lub hardness thiab tensile zog ua tau raws li qhov yuav tsum tau ua.
Daim ntawv thov:
Thaum tshav kub kub resistant conveyor siv yog dav siv nyob rau hauv metallurgy, tsev cov ntaub ntawv, casting, coking, tshuaj thiab lwm yam lag luam los thauj sinter, coke, cement, chiv thiab lwm yam kub kub khoom, nrog rau cov kev kub ceev tsis kam.
