Daim ntawv thov khoom: Qws thiab bar, Sheet thiab phaj, caster, luag cov menyuam, kev faib tshuaj ntsuam, coupling, Roj- yeeb nkab ntxuav, sealing nplhaib, cyclone, scraper thiab lwm yam khoom.

Cov ntsiab lus ntawm kev ua haujlwm:

Tom qab lub tshuab nqus tsev degasing ntawm 80-85 degree, lub prepolymer yog tov nrog melted MOCA rau casting thiab vulcanization. Nws yog haum rau phau ntawv thiab txhua yam kev ua haujlwm.

Cia:

Khaws rau hauv qhov chaw txias thiab qhuav thiab siv kom sai li sai tau tom qab qhib; Yog tias nws tsis tuaj yeem siv rau ib zaug, nws yuav tsum tau ntim nrog nitrogen; Qhov thib ob qhib yuav tsum tau siv rau defoaming, thiab thawj lub sij hawm cia yog rau lub hlis.
