HEMC rau Putty

HEMC, los yog hydroxyethyl methyl cellulose, yog ib qho tseem ceeb muaj nyob rau hauv putty formulations.Nws yog cov dej-soluble polymer uas yog siv los ua cov thickener, binder, thiab rheology modifier.HEMC yog muab los ntawm cellulose thiab yog ib qho uas tsis yog-ionic, non-toxic, thiab tsis-flammable compound.

Nyob rau hauv putty formulations, HEMC feem ntau yog siv los ua thickener thiab binder.Qhov sib ntxiv ntawm HEMC rau qhov sib tov pab txhim kho kev ua haujlwm ntawm lub putty thiab tso cai rau kev tswj xyuas cov ntsiab lus dej zoo dua.Qhov no yog qhov tseem ceeb vim tias cov ntsiab lus dej ntawm putty cuam tshuam rau nws qhov sib xws, teeb tsa lub sijhawm, thiab lub zog kawg.

Ib qho txiaj ntsig tseem ceeb ntawm HEMC hauv cov txheej txheem putty yog nws lub peev xwm los txhim kho qhov adhesion ntawm putty rau substrates.HEMC ua raws li kev sib khi, tsim kom muaj kev sib raug zoo ntawm cov putty thiab qhov chaw uas nws siv rau.Qhov no yog tshwj xeeb tshaj yog ib qho tseem ceeb nyob rau hauv daim ntawv thov qhov twg lub putty yuav raug kev nyuaj siab, xws li nyob rau hauv txhaws qhov khoob thiab tawg nyob rau hauv cov phab ntsa.

HEMC kuj tseem pab tiv thaiv kev sib cais ntawm ntau yam khoom hauv cov txheej txheem putty.Qhov no yog ib qho tseem ceeb vim hais tias lub putty zoo sib xyaw kom ntseeg tau tias nws yuav muaj cov khoom sib xws thiab yuav ua tau raws li qhov xav tau.

Lwm qhov txiaj ntsig ntawm HEMC hauv putty formulations yog nws lub peev xwm los txhim kho qhov khov-thaw tsis kam ntawm putty.Thaum dej khov, nws nthuav dav, uas tuaj yeem ua rau puas tsuaj rau lub putty.HEMC pab tiv thaiv qhov no los ntawm kev ua kom elasticity ntawm putty thiab txo cov dej uas muaj rau khov.

HEMC tseem ua lub luag haujlwm hauv rheology ntawm putty formulations.Rheology yog kev kawm txog kev ntws thiab deformation ntawm cov ntaub ntawv.Los ntawm kev kho tus nqi ntawm HEMC hauv kev sib tov, nws muaj peev xwm tswj tau cov khoom rheological ntawm putty.Qhov no tuaj yeem siv los tsim cov putties nrog cov yam ntxwv tshwj xeeb, xws li siab viscosity lossis thixotropy.

Ntxiv rau nws lub luag haujlwm hauv cov txheej txheem putty, HEMC kuj tseem siv rau ntau yam kev siv.Nws yog feem ntau siv los ua cov thickener thiab stabilizer hauv cov khoom noj khoom haus, nrog rau hauv cov khoom tu tus kheej xws li tshuaj zawv plaub hau thiab tshuaj pleev.HEMC kuj tseem siv los ua cov thickener thiab binder hauv kev tsim cov xim latex.

Zuag qhia tag nrho, HEMC yog ib qho tseem ceeb muaj nyob rau hauv putty formulations.Nws lub peev xwm los txhim kho kev ua haujlwm, adhesion, khov-thaw tsis kam, thiab rheological zog ntawm putties ua rau nws yog ib qho tseem ceeb ntawm kev siv ntau yam kev tsim kho.
