HEMC rau Putty nrog Kev Ua Haujlwm Zoo

HEMC, los yog Hydroxyethyl methyl cellulose, yog ntau yam thiab dav siv ntxiv uas tuaj yeem txhim kho cov khoom ntawm ntau yam khoom.Hauv kev tsim kho kev lag luam, HEMC feem ntau siv rau hauv putty los txhim kho nws cov kev ua tau zoo thiab zoo.Hauv tsab xov xwm no, peb yuav tham txog cov txiaj ntsig ntawm kev siv HEMC hauv putty, nrog rau cov yam ntxwv uas yuav tsum tau xav txog thaum xaiv thiab siv HEMC hauv daim ntawv thov no.

Putty yog ib hom khoom siv dav siv hauv kev tsim kho, tshwj xeeb tshaj yog rau kev kho thiab sau cov kab nrib pleb me me thiab qhov hauv cov phab ntsa thiab qab nthab.Nws yog cov hmoov qhuav uas feem ntau tov nrog dej los ua ib qho tshuaj txhuam uas tuaj yeem siv rau saum npoo.Ib qho ntawm cov teeb meem ntawm kev ua hauj lwm nrog putty yog ua kom tau raws li qhov xav tau sib xws thiab ua haujlwm tau zoo.Tshwj xeeb, putty tuaj yeem nyuaj rau kev sib tov thiab thov tusyees, thiab nws yuav tsis ua raws li qhov zoo ntawm qhov chaw lossis sau qhov khoob zoo.HEMC tuaj yeem pab daws cov teeb meem no los ntawm kev txhim kho cov kev ua haujlwm ntub dej, ua haujlwm tau zoo, thiab ua kom zoo ntawm cov putty.

Cov txiaj ntsig ntawm kev siv HEMC hauv Putty

Txhim kho Wetting Performance: Ib qho ntawm cov txiaj ntsig tseem ceeb ntawm kev siv HEMC hauv putty yog txhim kho kev ua haujlwm ntub dej.HEMC yog cov dej-soluble polymer uas tuaj yeem pab cov khoom ntub dej kom zoo dua qub, tso cai rau nws ua kom zoo dua thiab ua kom muaj qhov khoob zoo dua.Qhov no ua rau kev ua tiav smoother thiab kev ua tau zoo tag nrho.

Kev ua haujlwm zoo dua: HEMC tuaj yeem txhim kho kev ua haujlwm ntawm putty.Nws tuaj yeem pab txo cov viscosity ntawm cov khoom, ua kom yooj yim rau kev sib xyaw thiab siv.Qhov no tseem tuaj yeem pab txo qis cov dej uas xav tau hauv kev sib tov, uas tuaj yeem txhim kho tag nrho cov khoom zoo thiab ua haujlwm ntev ntawm cov khoom tiav.

Txhim kho Adhesion: HEMC tuaj yeem pab txhim kho qhov adhesion ntawm putty rau saum npoo.Qhov no tuaj yeem pab txo qis qhov tshwm sim ntawm kev tawg, tev, lossis lwm yam kev puas tsuaj.HEMC kuj tseem tuaj yeem pab txo qis qis thiab tawg, uas tuaj yeem txhim kho cov kav ntev thiab ntev ntawm cov khoom tiav.

Kev Ua Haujlwm Zoo: Ntxiv rau cov txiaj ntsig saum toj no, HEMC tseem tuaj yeem txhim kho kev tsim kho tag nrho ntawm cov putty.Qhov no suav nrog cov khoom xws li compressive zog, tensile zog, thiab flexural zog.Los ntawm kev txhim kho cov khoom no, HEMC tuaj yeem pab xyuas kom meej tias lub putty muaj peev xwm tiv taus cov kev ntxhov siab thiab kev siv ib txwm siv, thiab nws tseem muaj lub suab nrov dhau sijhawm.

Yam yuav tsum tau xav txog thaum siv HEMC hauv Putty

Hom HEMC: Muaj ntau ntau hom HEMC muaj, txhua tus muaj cov khoom sib txawv thiab cov yam ntxwv.Hom HEMC uas yog qhov zoo tshaj plaws rau putty yuav nyob ntawm seb yam xws li qhov xav tau sib xws, viscosity, thiab daim ntawv thov txheej txheem.Feem ntau, tsawg mus rau nruab nrab viscosity HEMC raug pom zoo rau cov ntawv thov putty.

Cov txheej txheem sib xyaw: Txhawm rau kom ntseeg tau tias HEMC tau muab faib ua tib yam thoob plaws hauv lub putty, nws yog ib qho tseem ceeb uas yuav tsum ua raws li cov txheej txheem sib xyaw kom haum.Qhov no feem ntau yog ntxiv HEMC rau hauv dej ua ntej thiab sib tov kom huv si ua ntej ntxiv cov hmoov.Nws yog ib qho tseem ceeb uas yuav tsum tau muab cov putty kom huv si kom paub meej tias HEMC yog sib npaug sib npaug thiab tsis muaj pob los yog clumps.

Tus nqi ntawm HEMC: Tus nqi ntawm HEMC yuav tsum tau ntxiv rau lub putty yuav nyob ntawm seb cov kev cai tshwj xeeb ntawm daim ntawv thov.Feem ntau, ib qho concentration ntawm 0.2% mus rau 0.5% HEMC los ntawm qhov hnyav ntawm cov hmoov yog pom zoo rau kev ua kom pom kev ntub dej, ua haujlwm tau zoo, thiab adhesion.Txawm li cas los xij, tus nqi ntawm HEMC xav tau yuav txawv nyob ntawm seb hom putty siv
