Tig Siab Torque, Tuag Drool, lossis Tsis Txaus Ntsig hauv LSZH Cable Compounds?
Cov khoom siv hluav taws xob tsawg Halogen-Free (LSZH) yog qhov tseem ceeb rau kev nyab xeeb thiab kev ruaj ntseg ntawm cable niaj hnub. Txawm li cas los xij, kev ua tiav cov txheej txheem ua tau zoo tseem yog qhov nyuaj. Kev siv hnyav ntawm cov nplaim hluav taws kub-xws li txhuas hydroxide (ATH) thiab magnesium hydroxide (MDH) - feem ntau ua rau cov dej ntws tsis zoo, lub zog siab siab, qhov chaw ntxhib tiav, thiab tuag tsim thaum lub sij hawm extrusion.
Vim li cas LSZH Cable Compounds nyuaj rau txheej txheem?
Cov yam ntxwv ntawm cov pa hluav taws xob tsawg halogen-dawb nplaim hluav taws xob thiab cable yog tias tag nrho cov ntaub ntawv tsis muaj halogen, thiab cov pa luam yeeb tsawg heev yuav raug tso tawm thaum lub sij hawm combustion. Txhawm rau ua tiav ob yam tseem ceeb no, ntau tus nplaim hluav taws xob tau ntxiv rau hauv cov txheej txheem tsim khoom, uas ncaj qha ua rau muaj teeb meem kev ua haujlwm.
Cov hauv qab no yog cov kev mob tshwm sim ntawm cov pa hluav taws xob tsawg halogen-free cable compounds:
1. Vim muaj cov nplaim hluav taws kub ntau ntxiv xws li aluminium hydroxide thiab magnesium hydroxide ntxiv, uas ua rau muaj peev xwm ntws tsis zoo, thiab kev sib txhuam thaum tshav kub kub ua rau kub nce, uas ua rau degradation ntawm aluminium hydroxide thiab magnesium hydroxide.
2. Tsawg extrusion efficiency, thiab txawm ntau dua extrusion ceev, lub peev xwm extrusion tseem tsis hloov.
3. Vim tsis zoo sib xws ntawm polyolefins nrog nplaim retardants thiab lwm yam fillers, uas ua rau tsis zoo dispersion thaum lub sij hawm ua thiab txo cov neeg kho tshuab zog.
4. Qhov tsis sib xws ntawm cov nplaim hluav taws xob tsis sib xws hauv lub cev ua rau lub ntsej muag ntxhib thiab tsis muaj gloss thaum lub sij hawm extrusion.
5. Cov txheej txheem polarity ntawm nplaim retardant thiab lwm yam fillers ua rau lub yaj mus rau lub taub hau tuag, ncua cov khoom demoulding, los yog nag lossis daus ntawm cov molecules tsawg nyob rau hauv formulation, uas ua rau cov khoom tsub zuj zuj ntawm lub qhov ncauj tuag, yog li cuam tshuam rau qhov zoo ntawm cable.
Yuav ua li cas los daws cov LSZH cable cov txheej txheem teeb meem thiab nto zoo?
Kom kov yeej cov teeb meem no,silicone masterbatch technologytau dhau los ua kev ntseeg siab nyob rau hauv LSZH compound formulations, txhim kho ob qho tib si kev ua haujlwm thiab kev ua haujlwm saum npoo yam tsis muaj kev cuam tshuam cov khoom siv hluav taws xob lossis hluav taws xob.
Yog vim li cassilicone masterbatch kev daws teeb meem zoorau kev txhim kho kev ua thiab kev ua haujlwm saum npoo ntawm LSZH cable compounds?
Silicone masterbatch yog ib homua hauj lwm additivenrog ntau yam thermoplastics raws li cov neeg nqa khoom thiab polysiloxane ua qhov chaw ua haujlwm. Ntawm qhov tod tes, silicone raws li masterbatch tuaj yeem txhim kho qhov muaj peev xwm ntawm cov txheej txheem thermoplastic thaum lub sij hawm molten, zoo dua cov dispersion ntawm fillers, txo lub zog noj ntawm extrusion thiab txhaj tshuaj molding, thiab txhim kho cov efficiency ntau lawm; Ntawm qhov tod tes, qhov kev pabcuam Silicone-raws li kev pabcuam no tuaj yeem txhim kho qhov smoothness ntawm cov khoom yas zaum kawg, txo qhov kev sib txhuam coefficient thiab txhim kho qhov hnav thiab khawb tsis kam. Tsis tas li ntawd, raws li kev ua haujlwm pabcuam rau kev lag luam thermoplastic, silicone masterbatch tuaj yeem ua tiav qhov kev hloov kho pom tseeb nrog tus nqi me me (< 5%), yam tsis muaj kev xav ntau dhau ntawm nws cov tshuaj tiv thaiv nrog cov khoom siv matrix.
Chengdu Silike Technology Co., Ltd. yog ib lub chaw tsim khoom hauv Suav teb tshwj xeeb hauvsilicone-raws li additivesrau plastics thiab roj hmab industries. Nrog ntau tshaj 20 xyoo ntawm kev mob siab rau kev tshawb fawb tsom rau kev sib koom ua ke ntawm silicone thiab polymers, Silike tau tsim nws tus kheej ua tus khub tshiab thiab ntseeg siab rau cov kev ua tau zoo ntxiv rau kev daws teeb meem.
Txhawm rau pab cov tuam txhab lag luam hauv kev tshawb nrhiav cov teeb meem tsim khoom cuam tshuam txog LSZH cables, Silike tau tsim cov ntaub ntawv qhia txogsilicone yas additivestshwj xeeb tsim los txhim kho cov txheej txheem ntawm cov kab sib txuas. Cov khoom lag luam tseem ceeb, xws li Silicone Masterbatch LYSI-401 thiab Silicone Masterbatch LYSI-502C, muab cov kev daws teeb meem zoo rau kev txhim kho kev ua haujlwm thiab qhov zoo ntawm qhov chaw, yog li ua rau muaj kev ua tau zoo hauv kev siv hlau thiab cable.
Cov txiaj ntsig kev ua tau zoo: Cov txiaj ntsig zoo ntawm Silicone Masterbatch hauv LSZH Cable Compounds
Ntxiv SILIKESilicone Masterbatch (Siloxane Masterbatch) LYSI seriesmus rau cov nplaim hluav taws kub-retardant filling system ntawm cov pa luam yeeb halogen-dawb cov khoom siv hluav taws xob tuaj yeem txhim kho kev ua haujlwm fluidity, txo torque, thiab txhim kho kev tsim khoom. Daim duab 1 qhia qhov kev sib piv ntawm kev ua haujlwm cable tom qab ntxiv 1%LYSI-401 silicone masterbatchnyob rau hauv peb lub tuam txhab simulated feem ntau cov pa luam yeeb halogen tsis pub mis mis (Table 1). Nws tuaj yeem pom tias qhov kev ua tau zoo cuam tshuam tau zoo dua qub.
Fig.2 , Fig.3, thiab Daim duab 4 qhia qhov ntsuas torque rheometer ntawm siloxane Cov ntsiab lus siabSilicone masterbatch LYSI-502Cntxiv rau cov qauv uas tsis muaj pa luam yeeb halogen-dawb thiab kev sib piv nrog cov torque, siab, thiab shear viscosity ntawm cov khoom sib tw txawv teb chaws. Nws tuaj yeem pom tias LYSI-502C muaj lubrication zoo heev.
Daim duab 5 muab qhov muaj txiaj ntsig simulation ntawm cov khoom sib txuam hauv ib qho cable extrusion tuag tom qab qhov sib ntxiv ntawm silicone masterbatch. Cov txiaj ntsig tau qhia tias kev suav nrog tus qauv silicone masterbatch txo qis kev tuag. Tsis tas li ntawd, SILIKE'ssiab molecular hnyav silicone masterbatchshowcases ib tug txawm ntau pronounced nyhuv nyob rau hauv minimizing tuag buildup, qhia nws lub peev xwm rau txhim khu kev ua hauj lwm efficiency.
Cov ntsiab lus:Siloxane muaj nyob rau hauv tus qauvsilicone masterbatchyog nonpolar, uas tuaj yeem tsim cov kev sib tw muab qhov sib txawv solubility tsis sib xws ntawm feem ntau carbon saw polymers. Thaum qhov sib ntxiv yog ntau dhau, nws yuav ua rau muaj teeb meem xws li ntsia hlau plam, lubrication ntau dhau, delamination ntawm cov khoom nto, kev cuam tshuam kev sib raug zoo, thiab tsis sib xws nyob rau hauv lub substrate.
Txhawm rau daws cov teeb meem no, SILIKE tau tsim ntau yamultra-siab molecular hnyav silicone additivesuas tau hloov kho nrog cov pab pawg ua haujlwm tshwj xeeb. Cov nosilicone-raws li polymer ua additivesyog tsim los ua kom tau raws li cov kev thov tshwj xeeb thoob plaws ntau lub tshuab thermoplastic. Los ntawm kev ua raws li cov thauj tog rau nkoj hauv substrate, lawv txhim khu kev sib raug zoo, txhim kho dispersion, thiab ntxiv dag zog rau adhesion. Qhov no ua rau muaj kev txhim kho zoo ntawm tag nrho cov substrate kev ua tau zoo. Hauv cov pa hluav taws xob tsawg, tsis muaj halogen, cov khoom siv tshiab no tuaj yeem tiv thaiv cov ntsia hlau plam thiab txo qis cov khoom siv tuag.
