Daim Ntawv Thov Ntau

HP-669 yog siv tau zoo nyob rau hauv kev lag luam roj hmab raws li ib tug dual functional organic poly sulfur silane coupling neeg sawv cev.
HP-669 tuaj yeem siv rau hauv cov roj hmab vulcanized nrog cov khoom ntim xws li silica, fiberglass, talc hmoov, mica hmoov thiab av nplaum ua tus neeg sawv cev.Nws tuaj yeem txhim kho cov khoom siv ntxiv ntawm cov fillers thiab roj hmab abrasive tsis kam.
Nws yog tsim nyog siv los ua cov roj hmab additive-vulcanizing tus neeg saib xyuas thiab activator hauv polymers xws li NR, IR, SBR, BR, NBR thiab EPDM.
Nyob rau hauv cov txheej txheem ntawm vulcanization, tus crosslinking tus nqi ntawm poly-sulfur alkyl yog tib yam li deoxidizing tus nqi ntawm leej faj, yog li nws ua los tiv thaiv deoxidization ntawm vulcanization, thiab ces txhim kho dynamic dabtsi yog khoov zog xws li tshav kub tsim thiab tawg expansion .Cov plaub leej faj atoms tuaj yeem ua tus activator rau vulcanization.
Nyob rau hauv dynamic thiab zoo li qub, Nws yog siv los tsim cov khoom siv roj hmab no: log tsheb, hose, roj hmab yob, txoj siv sia, cable, khau khiab thiab cov khoom tsim kho tshuab.Nws tuaj yeem txhim kho abrasive tsis kam, txiav tsis kam thiab siab ua haujlwm, txo hysteresis poob thiab hygroscopicity, txhim kho cov khoom siv thiab nplaum, thiab ua kom cov thermal aging kev ua haujlwm, modulus thiab flex lub neej.
Ntxiv sulfur-silane coupling tus neeg sawv cev hauv kev lag luam ntawm cov log tsheb, nws tsis yog tsuas yog debase qhov kev pheej hmoo ntawm kev sib tsoo raws li qhov kub thiab txias heev khiav ntawm txoj kev kub ceev los yog lub sij hawm ntev, tab sis kuj txo cov yob tsis kam ntawm cov log tsheb, tom qab ntawd txo cov kev siv roj av, emissions kom muaj nuj nqis ntawm CO2 raws li kev tiv thaiv ib puag ncig ntawm carbon txo.
