Siloxane hmoov(feem ntau yog cov organic siloxane hmoov los yog siloxane masterbatch) yog ib qho khoom siv zoo heev uas cuam tshuam rau cov khoom ntawm ABS resin (acrylonitrile-butadiene-styrene copolymer). Nws txhim kho lubrication, dispersion, thiab interfacial compatibility, ua rau nws zoo tagnrho rau kev hloov cov khoom. Cov tshuaj ntxiv no tau siv dav los txhim kho kev ua tau zoo, kev ua haujlwm ntev, thiab cov khoom siv tawv tawv-tshwj xeeb hauv ABS cov ntaub ntawv kaw lus xws li cov khoom vaj khoom tsev, cov khoom siv hluav taws xob, thiab cov neeg siv khoom siv plhaub- qhov twg nws txo cov khawb, txhim kho cov tsos, thiab txuas ntxiv lub neej kev pab cuam. Hauv kev ua haujlwm ntawm ABS plhaub, yam twg yuav cuam tshuam Siloxane hmoov? Wb tshawb nrhiav ua ke
1. Qhov cuam tshuam rau kev ua tau zoo
Txhim kho Flowability thiab Lubrication: Silosane hmoov txo qis yaj viscosity, boosts yaj ntws tus nqi, ua kom zoo dua pwm sau thiab tso tawm yooj yim dua, txo torque thiab siv zog, thiab ua kom tag nrho cov kev ua tau zoo rau ABS enclosure manufacturing.
Tsawg ua haujlwm tsis raug: Hauv kev txhaj tshuaj molding lossis extrusion, nws txo qis kev sib txhuam- thiab shear-induced degradation, tiv thaiv kev tuag buildup thiab ntsia hlau slippage-tshwj xeeb tshaj yog muaj txiaj ntsig nyob rau hauv cov tshuab ntim khoom siv rau cov ntaub ntawv ruaj khov.
2. Qhov cuam tshuam rau cov cuab yeej cuab tam
Txhim khu kev cuam tshuam toughness thiab hnav tsis kam: Nws txhawb nqa kev sib cais ntawm cov roj hmab theem, ua rau muaj kev cuam tshuam lub zog (txawm tias qhov kub thiab txias) thiab ua kom zoo dua hnav thiab khawb, uas pab tiv thaiv cov khoom tiav.
Cov nyhuv me me ntawm Tensile Strength: Thaum lub zog tensile yuav txo qis me ntsis, tag nrho toughness thiab yield stress nyob twj ywm; Kev noj tshuaj kom tsim nyog ua kom zoo tshaj plaws kev ua haujlwm txhua yam.
Cov txiaj ntsig ntxiv: Txo qhov shrinkage thiab txhim kho qhov ruaj khov, ua rau nws haum rau siab - daim ntawv thov ua haujlwm ntev.
3. Qhov cuam tshuam rau ntawm qhov chaw thiab qhov tshwm sim
Superior Scratch Resistance thiab Gloss: Ua kom txo tau qhov sib txhuam coefficient ntawm qhov chaw (piv txwv li, mus txog 0.39), ua rau cov cwj mem hardness (txog F qib), ua kom zoo nkauj, zoo nkauj, thiab txo qhov khawb thiab ua kom dawb huv - tseem ceeb rau qhov zoo nkauj ntawm ABS cov khoom ntim.
Tsis muaj teeb meem tsiv teb tsaws chaw: Tsis zoo li qis-molecular- hnyav lubricants, silicone hmoov nyob twj ywm nyob rau hauv qhov chaw tsis los ntshav tawm, khaws cia ntev - lub sij hawm gloss thiab optical clarity.
4. Qhov cuam tshuam rau thermal thiab lwm yam khoom
Zoo heev Thaum tshav kub kub Resistance thiab Stability: Muab kev ua tau zoo los ntawm -50℃txog 250 degree, tsis muaj coking lossis volatilization thaum lub sijhawm ua haujlwm kub, ntxiv rau huab cua zoo dua thiab cov khoom tiv thaiv zoo.
Txhim kho Filler Compatibility: Txhim kho kev sib cais ntawm cov khoom siv tsis zoo (xws li iav fibers) hauv ABS, txo cov agglomeration thiab boosting composite kev ua tau zoo tag nrho.
Qhov zoo tshaj qhov nyiaj ntxiv hauv ABS Enclosures
ABS enclosures (piv txwv li, cov khoom siv plhaub lossis cov cuab yeej ntsuas vaj tsev) muab qhov tseem ceeb tshaj plaws ntawm kev khawb av, hnav tsis kam, thiab ua haujlwm tau zoo. Qhov pom zoo silicone hmoov ntxiv yog feem ntau0.4% mus rau 1.0% los ntawm qhov hnyav. Cov ntsiab lus tseem ceeb:
0.4%: Muab qhov zoo tshaj plaws tag nrho cov nyiaj tshuav- txhim kho cov roj hmab theem dispersion, cuam tshuam lub zog, thiab cov khoom saum npoo thaum ua rau tsuas yog txo qis hauv lub zog siv tshuab.
0.3% txog 1.0%: Zoo tagnrho rau boosting nto smoothness thiab khawb kuj; yooj yim lub cev sib tov thaum lub sij hawm ua hauj lwm zoo. Nyob rau hauv siab -gloss tsis pleev xim ABS, 1% ntxiv tuaj yeem ua tiav F- theem cwj mem tawv nrog qhov tsis zoo gloss poob.
Qib siab (2% txog 5%): Tshwj xeeb rau kev hnav tsis zoo-kev xav tau kev tiv thaiv (xws li, hnyav- lub luag haujlwm lossis qhov chaw ua haujlwm abrasive), txawm hais tias lawv tuaj yeem cuam tshuam me ntsis lub zog thiab ci ntsa iab-ib txwm txheeb xyuas los ntawm kev sim.
Pib nrog 0.4% thiab kho raws li cov kev ntsuam xyuas tshwj xeeb (kev sib txhuam coefficient, kev cuam tshuam lub zog, thiab lwm yam) txhawm rau tiv thaiv dhau - ntxiv los ntawm kev cuam tshuam kev ua haujlwm. Hauv kev tsim khoom, sib txuas cov hmoov silosane nrog lwm cov khoom siv ntxiv (xws li cov nplaim hluav taws xob) tuaj yeem ua rau cov txiaj ntsig zoo dua rau kev thov cov ntawv thov ABS.
