Daim ntawv thov
PDM raws li kev ua haujlwm ntawm cov tshuaj roj hmab hauv kev ua cov roj hmab rau cov tshuaj tua kab mob kuj tseem tuaj yeem pab lub cev tuaj yeem siv rau peroxide curing agent, kuj tuaj yeem siv los ua cov tshuaj tiv thaiv -scorching agent thiab tackifier, ob qho tib si rau kev dav dav - cov roj hmab lub hom phiaj, kuj tseem siv tau rau cov roj hmab tshwj xeeb thiab roj hmab thiab siv cov kab ke. Nyob rau hauv tej yam ntuj tso roj hmab, thiab sulfur kev sib koom ua ke los tiv thaiv kev thim rov qab los txhim kho cov cua sov, txo cov cua sov, tiv thaiv -aging, txhim kho adhesion ntawm cov roj hmab thiab cov log tsheb thiab cov vulcanized roj hmab modulus. Lub xub pwg nyom rau cov log tsheb thauj khoom, cov roj hmab tsis muaj txheej, daws qhov teeb meem ntawm kev tsis ncaj ncees ntawm lub tsheb log tsheb sib cais kuj tseem siv tau rau loj - loj tuab cov khoom siv roj hmab thiab ntau yam roj hmab sundries. PDM tuaj yeem siv los ua tus neeg sawv cev kho mob, tuaj yeem txhim kho kev sib raug zoo ntawm kev sib raug zoo, ua kom cov cua sov ua haujlwm, haum rau qhov kub kub kho qhov system, txo qhov compression yog qhov pom tseeb, tab sis kuj txo cov peroxide, tiv thaiv kev ua cov roj hmab hauv kev kub siab, txhim kho lub log tsheb thiab roj hmab thiab hlau daim ntawv cog lus. PDM yog ib qho tsis yog -sulfur vulcanizing tus neeg sawv cev rau cov roj hmab cable, nws tuaj yeem hloov thiazoles, thiuram thiab tag nrho cov sulfur vulcanizing tus neeg sawv cev, kev daws ntawm tooj liab hlau thiab tooj liab hluav taws xob tsim vim raug cov sulfur vulcanizing tus neeg sawv cev dub tooj liab sulfide kab mob teeb meem. Raws li tus neeg sawv cev scorch rau 0.5-1.0 daim ntawv, raws li tus neeg saib xyuas kev kho rau 2-3, txhawm rau txhim kho cov compressive deformation ntawm 1.5 daim ntawv, txhim kho cov nplaum nplaum ntawm 0.5-5.0 daim ntawv.
Ntim
