Yuav ua li cas los daws cov teeb meem kev ua haujlwm ntawm cov khoom siv hluav taws xob tsis muaj pa taws tsawg halogen?

LSZH sawv cev rau cov pa luam yeeb tsawg xoom halogens, tsis muaj pa luam yeeb halogen-dawb, hom kab no thiab xaim tawm cov pa luam yeeb tsawg heev thiab tsis muaj tshuaj lom halogens thaum raug tshav kub. Txawm li cas los xij, txhawm rau ua tiav ob lub ntsiab lus tseem ceeb no, hauv kev tsim cov khoom siv hluav taws xob tsis tshua muaj pa halogen-dawb, Cov pa hluav taws xob qis qis halogens (LSZH) hnyav hnyav, uas tseem ncaj qha ua rau cov khoom siv hluav taws xob & kev ua haujlwm.

Cov teeb meem hauv kev ua cov khoom siv tsis muaj pa halogen tsawg:

1. Cov mis tsis tu ncua, LLDPE / EVA / ATH cov ntsiab lus siab tau sau LSZH polyolefin cable compounds muaj txog li 55-70% ATH / MDH, Raws li ntau tus aluminium hydroxide, magnesium hydroxide, thiab lwm yam nplaim taws retardants los koom nrog kev siv lub cev. kev txav mus los tsis zoo, kev sib txhuam ntawm cov cua sov thaum lub sijhawm ua haujlwm ua rau muaj qhov kub thiab txias uas ua rau degradation ntawm txhuas thiab magnesium hydroxide.

2. Tsawg extrusion efficiency, txawm hais tias koj nce qhov ceev ntawm extrusion ntim tseem yeej ib yam.

3. Kev sib raug zoo tsis zoo ntawm cov nplaim hluav taws tsis zoo thiab cov khoom ntim nrog polyolefins, tsis zoo dispersion thaum ua, ua rau txo cov khoom siv kho tshuab.

4. Rough nto thiab tsis muaj gloss thaum extrusion vim uneven dispersion ntawm inorganic nplaim retardants nyob rau hauv lub system.

5.Cov txheej txheem polarity ntawm cov nplaim hluav taws kub thiab cov khoom ua kom cov yaj ua rau lub taub hau pwm, ncua kev tso tawm ntawm cov khoom los ntawm pwm, lossis cov khoom me me hauv cov txheej txheem precipitate tawm, uas ua rau cov khoom tsim ntawm pwm qhib, yog li cuam tshuam qhov zoo ntawm cable.

Raws li cov teeb meem saum toj no, SILIKE tau tsim cov koobsilicone additiveCov khoom tsim tshwj xeeb tsim los daws cov ntsiab lus mob ntawm kev ua tiav thiab qhov zoo ntawm cov khoom siv hluav taws xob tsis muaj pa halogen-dawb, tsis muaj pa luam yeeb xoom halogens hlau & cable sib txuas, lossis lwm yam khoom siv hauv polyolefin compounds rau hlau thiab cable, muab ntau yam kev daws teeb meem zoo. rau cov kev cov nyom no.

Piv txwv li:Silicone Masterbatch (Siloxane Masterbatch) LYSI-401yog pelletized formulation nrog 50% ultra-siab molecular hnyav siloxane polymer dispersed nyob rau hauv tsawg-density polyethylene (LDPE). Nws yog dav siv los ua cov khoom siv tau zoo hauv PE-compatible resin systems los txhim kho cov khoom ua haujlwm thiab hloov kho qhov zoo.

Ntxiv 0.5-2% ntawmSILIKE silicone masterbatch LYSI-401rau cov nplaim hluav taws kub retardant filling system ntawm cov pa luam yeeb tsawg halogen dawb xaim & cable sib txuas lossis cov khoom siv hluav taws xob tsis tshua muaj hluav taws xob halogens (LSZH) cov khoom siv hluav taws xob ua rau cov xaim thiab cable tsim kom muaj txiaj ntsig zoo, tuaj yeem txhim kho kev ua haujlwm fluidity, txo cov torque, sai dua nto extrusion kab ceev yam tsis muaj Kev tsiv teb tsaws, txhim kho qhov zoo ntawm cov hlau thiab cable zoo ib yam, (qis coefficient ntawm kev sib txhuam, Txhim kho khawb thiab hnav tsis kam, zoo dua nto plam, thiab txhais tes zoo li ...) yam tsis tau them tus nqi them rau cov khoom siv ntxiv uas tsis xav tau.

Feem ntau, rau Ordinarysilicone masterbatch, siloxane tsis yog-polar, thiab feem ntau ntawm cov pa roj carbon saw polymer solubility tsis txawv ntawm qhov sib txawv yog qhov loj heev, qhov sib ntxiv ntawm cov neeg coob coob tuaj yeem ua rau kev ua cov ntsia hlau slippage, lubrication ntau dhau, qhov chaw ntawm cov khoom delamination, cuam ​​tshuam rau saum npoo ntawm cov khoom ntawm cov khoom sib txuas ntawm cov khoom hauv substrate dispersed unevenly thiab lwm yam.

Thaum,SILIKE's ultra-siab molecular hnyav silicone additivestau hloov kho los ntawm cov pab pawg tshwj xeeb, uas tuaj yeem xaiv thiab sib tw raws li qhov sib txawv ntawm cov khoom siv silicone additives hauv cov substrates sib txawv. Cov khoom lag luam no tuaj yeem ua lub luag haujlwm ntawm kev thauj mus los hauv substrate, yog li kev sib raug zoo nrog lub substrate, yooj yim dispersion, muaj zog sib txuas, thiab yog li muab cov substrate ntau dua kev ua tau zoo. Thaum siv hauv LZSH thiab HFFR tshuab, nws tuaj yeem ua kom tsis txhob muaj cov ntsia hlau slippage thiab tseem tuaj yeem ua lub luag haujlwm tseem ceeb hauv kev txhim kho cov khoom sib txuam hauv lub qhov ncauj pwm.
