Cov cua txias masterbatch tau pib siv hauv PP spinning processing, thiaj li yuav txo tau cov viscosity siab ntawm PP thiab tiv thaiv cov decomposition ntawm lwm yam additives, pigments, thiab lwm yam. Cov cua txias masterbatch tuaj yeem txo qhov hnyav molecular ntawm PP, yog li txo qhov ua haujlwm kub ntawm PP. Nws cov khoom tseem ceeb yog peroxide. Tam sim no, daim ntawv thov ntau yam ntawm cov cua txias masterbatch tau nthuav dav, thiab nws tau dhau los ua ib qho ntxiv rau qee qhov PP hloov kho cov tuam txhab, tshwj xeeb tshaj yog nyob rau hauv kev tsim cov PP siab (xws li loj nyias-walled cia chim hauv khw muag khoom).
Cov cua txias masterbatch feem ntau yog siv rau polypropylene spinning. Vim yog qhov hnyav molecular ntawm polypropylene, qhov kub thaum lub sij hawm spinning yog siab li 300 ° C los yog ntau tshaj. Qhov no ua rau nws yooj yim rau decompose additives, pigments, thiab lwm yam. Cov cua txias masterbatch feem ntau yuav txo tau lub spinning kub los ntawm 10 ~ 50 ° C thiab txhim kho cov txheej txheem spinning. Tus neeg sawv cev pabcuam siv rau cua txias masterbatch tiag tiag yog peroxide. Cov neeg pib siv feem ntau A yog di-tert-butyl peroxide (DTBP), uas yog cov kua daj me ntsis pob tshab, nrog rau qhov kub ntawm 110 ° C, qhov hluav taws kub ntawm 182 ° C, thiab kub decomposition. Nws yog 193 ° C (ib nrab-lub neej ntawm 1 feeb) thiab 126 ° C (ib nrab-lub neej ntawm 10 teev).
Polypropylene cua txias masterbatch PA-520 yog peroxide xim masterbatch, siv nyob rau hauv polyolefin tebchaw los ua kom nws yaj Performance index.
Nws muaj 5%:
[DHBP, 2.5-Dimethyl, 1-2.5-bis (tert-butylperoxy)-hexane], ([2.5-Dimethyl, 1-2.5-di (tert .Butylperoxy)-hexane])
PA-520 yog qhov zoo tagnrho rau kev siv fiber ntau. Polyolefin txhaj moulds rau high-speed molding los yog nyias-walled khoom coj cov khoom muaj zog heev. Lwm qhov zoo dua yog txhawm rau txhim kho cov dej ntws ntawm cov khoom siv PP cov khoom siv rov ua dua tshiab.
Cov khoom siv yas ntau lawm feem ntau yuav tsum tau siv cov yas tov khoom thiab lub tshuab ziab khaub ncaws.Thaum koj cov khoom muaj xim sib txawv masterbatch, koj yuav tsum siv cov yas tov khoom raw nws.Xucai Environmental Technology tuaj yeem muab cov khoom siv ib-nres yas rov ua dua tshiab.
