Xov xwm

Silicone masterbatchyog ib hom tshuaj ntxiv hauv kev lag luam roj hmab thiab yas. Kev siv thev naus laus zis hauv kev ua haujlwm ntawm silicone additives yog kev siv ultra-high molecular hnyav (UHMW) silicone polymer (PDMS) nyob rau hauv ntau yam thermoplastic resins, xws li LDPE, EVA, TPEE, HDPE, ABS, PP, PA6, PET, TPU , HIPS, POM, LLDPE, PC, SAN, thiab lwm yam thiab raws li pellets thiaj li tso cai yooj yim ntxiv ntawm cov additive ncaj qha mus rau lub thermoplastic thaum lub sij hawm ua. combining zoo heev ua nrog tus nqi pheej yig. Lub silicone masterbatch yog ib qho yooj yim rau pub, los yog sib tov, rau hauv yas thaum lub sij hawm compounding, extrusion, los yog txhaj molding. Nws yog qhov zoo dua li cov roj ciab thiab lwm yam khoom siv ntxiv hauv kev txhim kho kev nplua thaum lub sijhawm tsim khoom. Yog li, yas processors nyiam siv lawv nyob rau hauv cov zis.

Lub luag haujlwm ntawmSilicone Masterbatch additivehauv kev txhim kho cov txheej txheem yas

Silicone masterbatch yog ib qho kev xaiv nrov tshaj plaws rau cov txheej txheem hauv kev ua cov yas thiab kev txhim kho saum npoo. Raws li ib yam ntawm super lubricant. Nws muaj cov haujlwm tseem ceeb hauv qab no thaum siv cov thermoplastic cob:

A. Txhim kho qhov ntws ntawm cov resin thiab kev ua haujlwm;

Zoo pwm filling thiab pwm tso tawm cov khoom

Txo cov extrude torque thiab txhim kho tus nqi extrusion;

B. Txhim kho resin cov khoom nto

Txhim kho cov yas nto tiav, du degree, thiab txo cov tawv nqaij sib txhuam coefficient, Txhim kho qhov hnav tsis kam thiab khawb tsis kam;

Thiab silicone masterbatch muaj qhov zoo thermal stability (thermal decomposition kub yog hais txog 430 ℃ hauv nitrogen) thiab tsis yog tsiv teb tsaws;

Kev tiv thaiv ib puag ncig;

Kev nyab xeeb tiv tauj nrog zaub mov.

Peb yuav tsum taw qhia tias tag nrho cov silicone masterbatches ua haujlwm yog muaj rau A thiab B (cov ntsiab lus saum toj no peb teev) tab sis lawv tsis yog ob lub ntsiab lus ywj pheej tab sis

ntxiv ib leeg, thiab muaj kev sib raug zoo.

Cov teebmeem ntawm cov khoom kawg

Vim yog cov yam ntxwv ntawm cov qauv molecular ntawm siloxane, qhov ntau npaum li cas me me yog li ntawm tag nrho yuav luag tsis cuam tshuam rau cov cuab yeej cuab tam ntawm cov khoom kawg. Feem ntau hais lus, tsuas yog elongation thiab cuam tshuam lub zog yuav nce me ntsis, tsis muaj kev cuam tshuam rau lwm yam khoom siv. Ntawm qhov ntau npaum li cas, nws muaj cov nyhuv synergistic nrog cov nplaim hluav taws kub.

Vim nws txoj kev ua tau zoo ntawm kev ua haujlwm siab thiab qis-kub, nws yuav tsis muaj kev cuam tshuam rau qhov siab thiab qis-kub tsis kam ntawm cov khoom kawg. Thaum cov dej ntws ntawm cov resin, kev ua, thiab cov khoom nto yuav raug txhim kho kom pom tseeb thiab COF yuav raug txo.

Action mechanism

Silicone masterbatchyog ultra-siab molecular hnyav polysiloxane dispersed nyob rau hauv sib txawv cab kuj resins uas yog ib yam ntawm cov muaj nuj nqi masterbatch. Thaum ultra-siab molecular hnyavsilicone masterbatchtau ntxiv rau hauv cov yas rau lawv cov tsis muaj polar thiab tsis tshua muaj zog saum npoo, nws muaj qhov sib txawv txav mus rau cov yas nto thaum lub sij hawm melting; thaum, txij li nws muaj qhov hnyav molecular, nws tsis tuaj yeem txav tawm tag nrho. Yog li peb hu nws kev sib haum xeeb thiab kev sib koom ua ke ntawm kev tsiv teb tsaws chaw thiab tsis yog kev tsiv teb tsaws chaw. vim cov cuab yeej no, ib txheej dynamic lubrication tsim ntawm cov yas nto thiab cov ntsia hlau.

Nrog kev ua haujlwm txuas ntxiv mus, cov txheej txheem lubrication no tau raug tshem tawm tas li thiab tsim tawm. Yog li cov dej ntws ntawm cov resin thiab kev ua haujlwm tau txais kev txhim kho tas li thiab txo cov hluav taws xob tam sim no, cov khoom siv torque thiab txhim kho cov zis. Tom qab ua tiav ntawm ntxaib-ntsia hlau, silicone masterbatches yuav muab sib npaug hauv cov yas thiab tsim 1 mus rau 2-micron roj particle nyob rau hauv lub microscope, cov roj hais yuav muab cov khoom zoo dua, zoo txhais tes zoo, qis COF, thiab ntau dua. abrasion thiab khawb kuj.

Los ntawm daim duab peb tuaj yeem pom tias silicone yuav dhau los ua cov khoom me me tom qab tawg mus rau hauv cov yas, ib yam uas peb yuav tsum tau taw qhia yog tias dispersibility yog qhov ntsuas tseem ceeb rau silicone masterbatches, me me ntawm cov khoom, qhov sib npaug sib npaug, qhov txiaj ntsig zoo dua. peb yuav tau.
