Cov khoom
iab saj. Lub ntiajteb txawj nqus: 1.10-1.40. Yooj yim soluble hauv chloroform, acetone thiab methanol. Soluble hauv benzene. Tsis yooj yim soluble hauv dej thiab roj av.
Daim ntawv thov
thiourea tshaj plaws rau vulcanization ntawm CR. Muab vulcanization ceev ceev ntawm qhov qis, nruab nrab thiab siab kub. Yuav siv tau los txhawb EPDM sulfur vulcanization tshuab. Tshwj xeeb tshaj yog haum rau siab - ceev CV txheej txheem. Siv hauv CR
Cov accelerators no muaj kev txhawb nqa qis thiab ua haujlwm tsis zoo los tiv thaiv- hlawv. Yog li ntawd, lawv tsis tshua siv rau diene-raws li roj hmab. Txawm li cas los xij, hauv qee qhov tshwj xeeb, xws li thaum siv coumarin sulfurizers lossis lwm yam tshuaj sulfur rau lub cev vulcanization, cov khoom no muaj kev ua haujlwm ntawm tus activator. Thiourea- hom accelerators muaj qhov ua tau zoo hauv cov vulcanization ntawm chloroprene roj hmab thiab tuaj yeem tsim cov chloroprene vulcanized roj hmab nrog cov khoom zoo xws li lub zog tensile, hardness, thiab compression mus tas li deformation. Piv nrog NA-22, cov khoom no muaj kev kub nyhiab thiab vulcanization, tab sis zoo dua vulcanization flatness. Nws yog ib qho yooj yim rau disperse thiab tsis flake. Thaum qhov ntau npaum li cas, nws tuaj yeem ua rau siab - kub thiab siab - ceev vulcanization, uas yog tshwj xeeb tshaj yog haum rau kev nruam vulcanization ntawm cov khoom molded. Cov khoom no kuj yog ib qho kev txhawb nqa rau butyl roj hmab thiab vulcanization activator rau ethylene propylene diene monomer roj hmab. Nws muaj cov teebmeem antioxidant ntawm cov roj hmab ntuj, chloroprene roj hmab, nitrile roj hmab, thiab styrene-butadiene roj hmab. Nws feem ntau yog siv rau kev tsim khoom lag luam. Cov xov hlau tshwj xeeb, cov khoom siv daim txhuam cev, thiab lwm yam.
Ntim
25kg yas woven hnab, ntawv nrog yas zaj duab xis hnab, kraft ntawv hnab.
Cia
Khaws lub thawv kaw kom nruj rau hauv qhov chaw txias, zoo - qhov cua. Qhov kev pom zoo siab tshaj plaws cia lub neej yog 2 xyoos thaum khaws cia hauv ib txwm muaj.
