Yuav ua li cas los txhim kho cov dispersion ntawm nplaim retardants

Nrog rau kev siv dav dav ntawm cov ntaub ntawv polymer thiab cov khoom siv hluav taws xob hauv lub neej niaj hnub, qhov xwm txheej ntawm hluav taws kuj tseem nce ntxiv, thiab qhov teeb meem nws coj yog qhov txaus ntshai. Cov nplaim retardant kev ua tau zoo ntawm cov ntaub ntawv polymer tau dhau los ua qhov tseem ceeb, nws yog txhawm rau ua kom tiav cov nplaim hluav taws xob ntawm cov khoom siv yas thiab roj hmab, txo cov plua plav paug los ntawm cov nplaim hluav taws kub, cov nplaim hluav taws kub hnyiab tau los ua, thiab ua lub luag haujlwm tseem ceeb thiab tseem ceeb hauv kev molding ntawm cov khoom kawg.

Nplaim retardant masterbatch yog tsim raws li tus qauv tsim nyog, los ntawm kev sib xyaw ua ke ntawm cov nplaim hluav taws, lubricant dispersant thiab cov cab kuj, los ntawm kev ua kom zoo, sib tov, sib xyaw thiab tom qab ntawd extrusion granulation. Nyob rau hauv no, lub dispersant plays ib tug tseem ceeb luag hauj lwm, ntxiv ib co kev faib ua feem ntawm dispersant yuav ua tau zoo heev los txhawb lub dispersion ntawm nplaim retardant, thiaj li hais tias nws yog ib qho yooj yim mus rau tusyees dispersed nyob rau hauv tus txheej txheem, los tiv thaiv lub agglomeration ntawm nplaim retardant, qhov zoo dua cov nyhuv dispersing, thiaj li yuav ua rau cov nplaim retardant molecules zoo dua cov nplaim taws ua rau nws zoo dua. retardant efficiency ntawm yas, cov khoom siv roj hmab, qhov hluav taws kub yuav raug strangled nyob rau hauv thaum ntxov theem.

Txawm li cas los xij, hauv kev xyaum, ntau yam khoom siv yas thiab roj hmab uas muaj cov khoom siv hluav taws xob tsis tuaj yeem ua rau lawv cov nplaim hluav taws tsis zoo vim qhov tsis sib xws ntawm cov nplaim hluav taws kub nyhiab hauv cov khoom siv hluav taws kub, uas ua rau muaj hluav taws loj thiab poob loj.

Txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau nws

SILIMER yog ib yam ntawm tri-block copolymerized hloov siloxane muaj li ntawm polysiloxanes, polar pawg thiab ntev carbon saw pawg. Cov ntu polysiloxane tuaj yeem ua lub luag haujlwm ntawm kev sib cais ntawm cov nplaim hluav taws xob molecules nyob rau hauv cov tshuab shear, tiv thaiv cov agglomeration theem nrab ntawm cov nplaim hluav taws xob molecules; cov polar pawg saw ntu muaj qee qhov kev sib txuas nrog cov nplaim hluav taws, ua si lub luag haujlwm ntawm kev sib txuas; qhov ntev carbon saw ntu muaj qhov zoo sib xws nrog cov khoom siv hauv paus.

Cov khoom lag luam no tsim nyog rau cov khoom siv thermoplastic, TPE, TPU thiab lwm yam thermoplastic elastomers, thiab tuaj yeem txhim kho kev sib raug zoo ntawm cov xim / muab cov hmoov / cov hmoov ua haujlwm thiab cov tshuab ua haujlwm, thiab ua kom lub xeev tawg ntawm cov hmoov ruaj khov.

Nyob rau tib lub sijhawm, nws tseem tuaj yeem txo cov viscosity ntawm cov yaj, txo lub zog ntawm extruder, extrusion siab, txhim kho kev ua haujlwm ntawm cov khoom, nrog kev ua haujlwm zoo lubrication, thiab tib lub sijhawm tuaj yeem txhim kho qhov xav tau ntawm cov khoom nto, nrog rau qee qhov kev sib tw thiab tsis cuam tshuam rau cov khoom siv hluav taws xob ntawm cov khoom siv, yog los txhawb cov retardant cov nyhuv ntawm cov nplaim hluav taws. cov khoom kawg muab kev ua si tag nrho rau cov kev daws teeb meem zoo.

Tsis tas li ntawd, cov khoom lag luam no tsis yog tsuas yog tsim rau cov nplaim hluav taws kub hnyiab, tab sis kuj rau cov xim masterbatch lossis cov ntaub ntawv siab ua ntej dispersed.
