Siv
Yuav luag tag nrho cov decomposition ntawm azo pib yog cov tshuaj tiv thaiv thawj zaug, tsuas yog ib hom dawb radical tsim, thiab tsis muaj cov tshuaj tiv thaiv sab, yog li nws tau siv dav hauv kev tsim khoom thiab kev tshawb fawb.Azo pib muaj cov khoom ruaj khov thiab yooj yim rau kev khaws cia thiab kev thauj mus los.Txawm li cas los xij, nws yuav tsum tau muab tso rau hauv tub yees thaum lub caij tsheb thauj mus los, thiab tiv thaiv kev sib tsoo hnyav, kev sib tsoo, thiab tawg.Cov khoom no yog tsuas yog siv rau tej polymerization, ncua kev kawm ntawv polymerization thiab tshuaj polymerization.
Daim ntawv thov
Nws tuaj yeem siv los ua tus pib rau lub polymerization ntawm ethylene monomers xws li methyl methacrylate, thiab tuaj yeem siv los ua tus neeg sawv cev foaming.
Cia tej yam kev mob / cia txoj kev
Cov khoom no raug kaw thiab khaws cia ntawm 2-6 ° C los tiv thaiv kev cuam tshuam thiab kev sib txhuam.
Cov khoom ntim
1kg ntim rau hauv lub hnab aluminium ntawv nyiaj, 50kgs ib daim duab los qhia nruas, kom paub meej thov confirem nrog muag.
Cov lus ceeb toom ntawm kev thauj mus los thiab kev khaws cia
Rau kev thauj mus los hauv cov ntim dej khov, nws yuav tsum tau muab ntim thiab khaws cia ntawm qhov kub qis dua 2-6 ° C.
