Uses
Kunenge kwese kuparara kweazo intiators ndeyekutanga-odha maitiro, imwe chete mhando yemahara radical inoumbwa, uye hapana padivi pekuita, saka inoshandiswa zvakanyanya mukugadzira maindasitiri uye kutsvagisa kwesainzi.Iyo azo initiator ine yakagadzikana zvivakwa uye yakanakira kuchengetedza nekufambisa.Zvisinei, inoda kuiswa mufiriji panguva yekufambisa, uye kudzivirira kudhumhana, kubonderana, uye kuputika.Ichi chigadzirwa chinonyanya kushandiswa kune yakawanda polymerization, kumiswa polymerization uye mhinduro polymerization.
Application
Inogona kushandiswa seyekutanga yepolymerization yeethylenic monomers senge methyl methacrylate, uye inogona zvakare kushandiswa seanopupa furo.
Mamiriro ekuchengetedza / nzira dzekuchengetedza
Ichi chigadzirwa chinovharwa uye chinochengetwa pa2-6 ° C kudzivirira kukanganisa uye kukwesha.
Product kurongedza
1kg yakarongedzwa mualuminium foil bag, 50kgs pamakadhibhodi chigubhu, kune ruzivo ndapota simbisai nekutengesa.
Zvinyorwa zvekufambisa uye kuchengetedza
Nekufambisa mumapaki echando, inofanirwa kuiswa chisimbiso uye kuchengetwa pane yakaderera tembiricha iri pasi pe2-6 °C.
