Yuav ua li cas los txhim kho qhov kev tawg ntawm cov nplaim taws retardants

Nrog rau kev siv dav dav ntawm cov ntaub ntawv polymer thiab cov khoom siv hluav taws xob hauv lub neej txhua hnub, qhov tshwm sim ntawm hluav taws kuj nce ntxiv, thiab qhov kev puas tsuaj uas nws coj los kuj tseem ceeb dua. Kev ua haujlwm ntawm cov nplaim taws ntawm cov ntaub ntawv polymer tau dhau los ua qhov tseem ceeb dua, nws yog txhawm rau ua tiav cov kev xav tau ntawm cov khoom yas thiab roj hmab, txo cov plua plav uas ua los ntawm cov nplaim taws retardants, nplaim taws retardant masterbatch tau tshwm sim, thiab ua lub luag haujlwm tseem ceeb thiab tseem ceeb hauv kev tsim cov khoom kawg.

Cov tshuaj masterbatch uas tiv taus hluav taws yog ua raws li cov mis tsim nyog, los ntawm kev sib xyaw ua ke ntawm cov tshuaj tua hluav taws, cov roj nplua nyeem thiab cov neeg nqa khoom, los ntawm kev ua kom huv si, sib tov, sib xws thiab tom qab ntawd extrusion granulation. Hauv qhov no, cov tshuaj dispersant ua lub luag haujlwm tseem ceeb heev, ntxiv ib feem ntawm cov tshuaj dispersant tuaj yeem ua rau cov tshuaj dispersant tawg tau zoo heev, yog li nws yooj yim tawg sib npaug hauv cov txheej txheem, tiv thaiv kev sib sau ua ke ntawm cov tshuaj tua hluav taws, qhov zoo dua qhov kev tawg, kom cov tshuaj tua hluav taws ua rau cov tshuaj tua hluav taws ua rau cov tshuaj tua hluav taws ua rau cov tshuaj tua hluav taws zoo dua, yog li txhim kho cov tshuaj tua hluav taws ntawm cov yas thiab roj hmab, hluav taws yuav raug nplawm thaum ntxov.

Txawm li cas los xij, hauv kev xyaum, ntau yam yas thiab roj hmab uas muaj cov khoom tiv thaiv hluav taws tsis tuaj yeem ua lawv cov khoom tiv thaiv hluav taws vim tias qhov sib txawv ntawm cov nplaim taws hauv cov khoom siv hauv hluav taws, uas ua rau muaj hluav taws loj dua thiab kev poob loj.

Txhawm rau txhawb kev sib xyaw ua ke ntawm cov nplaim taws retardants lossis nplaim taws retardant masterbatch hauv cov txheej txheem molding khoom, txo qhov tshwm sim ntawm kev sib xyaw tsis sib xws los ntawm cov nplaim taws retardant nyhuv tsis tuaj yeem ua haujlwm tau zoo, thiab lwm yam, thiab txhim kho qhov zoo ntawm cov nplaim taws retardant khoom, SILIKE tau tsim cov khoom hloov kho silicone SILIMER hyperdispersant.

SILIMER yog ib hom tri-block copolymerized modified siloxane uas muaj cov polysiloxanes, polar pawg thiab cov pa roj carbon ntev. Cov polysiloxane saw ntu tuaj yeem ua lub luag haujlwm cais tawm ntawm cov nplaim taws retardant molecules nyob rau hauv kev txiav tshuab, tiv thaiv kev sib sau ua ke ntawm cov nplaim taws retardant molecules; cov polar pawg saw ntu muaj qee qhov kev sib txuas nrog cov nplaim taws retardant, ua lub luag haujlwm ntawm kev sib txuas; cov pa roj carbon ntev ntu muaj kev sib raug zoo heev nrog cov khoom siv hauv paus.

Cov khoom no yog tsim rau cov thermoplastic resins, TPE, TPU thiab lwm yam thermoplastic elastomers, thiab tuaj yeem txhim kho qhov sib xws ntawm cov pigments / filler hmoov / functional hmoov thiab resin systems, thiab ua kom lub xeev dispersion ntawm cov hmoov ruaj khov.

Tib lub sijhawm, nws kuj tseem tuaj yeem txo qhov viscosity ntawm cov yaj, txo qhov torque ntawm lub extruder, extrusion siab, txhim kho kev ua tiav ntawm cov khoom siv, nrog rau kev ua kom zoo lubrication, thiab tib lub sijhawm tuaj yeem txhim kho qhov kev xav ntawm qhov chaw ntawm cov khoom siv, nrog rau qee qib ntawm kev du thiab tsis cuam tshuam rau cov khoom siv kho tshuab ntawm cov khoom siv, yog los txhawb kev sib xyaw ua ke ntawm cov khoom siv hluav taws xob-retardant los txhawb cov nplaim taws retardant nyhuv ntawm cov khoom kawg kom muab kev ua si tag nrho rau cov kev daws teeb meem zoo.

Tsis tas li ntawd xwb, cov khoom no tsis yog tsuas yog siv rau cov tshuaj masterbatch uas tiv taus hluav taws xwb, tab sis kuj siv rau cov xim masterbatch lossis cov khoom siv uas muaj cov khoom sib xyaw ua ntej.
