HEMC rau Putty Nrog Zoo Retention

Putty yog cov khoom siv feem ntau siv rau hauv kev tsim kho qhov khoob, tawg, thiab lwm yam tsis zoo. Txawm li cas los xij, kev tswj xyuas qhov sib xws thiab dej cov ntsiab lus ntawm putty tuaj yeem yog ib qho nyuaj, vim nws tuaj yeem qhuav los yog poob nws cov dej noo nyob rau lub sijhawm. Qhov no yog qhov uas siv Hydroxyethyl Methyl Cellulose (HEMC) los rau hauv. HEMC yog ib qho dej-soluble polymer uas tuaj yeem muab ntxiv rau putty los txhim kho nws cov dej tuav. Hauv tsab xov xwm no, peb yuav tham txog cov txiaj ntsig ntawm kev siv HEMC hauv putty nrog cov dej tuav zoo thiab cov ntsiab lus xav txog thaum siv HEMC hauv daim ntawv thov no.

Cov txiaj ntsig ntawm kev siv HEMC hauv Putty nrog dej tuav zoo

Txhim Kho Kev Ua Haujlwm Zoo: HEMC tuaj yeem pab txhim kho kev ua haujlwm ntawm putty los ntawm kev tswj kom zoo sib xws thiab cov ntsiab lus dej. Qhov no ua rau nws yooj yim rau kev sib tov thiab siv cov putty, kom ntseeg tau tias nws kis tau tusyees thiab smoothly thoob plaws qhov chaw. Tsis tas li ntawd, kev txhim kho kev ua haujlwm ntawm putty tuaj yeem pab txo qis kev siv zog thiab lub sijhawm xav tau los thov thiab ua kom tiav.

Txo Cracking thiab Shrinkage: HEMC tuaj yeem pab txo qis qhov tshwm sim ntawm kev tawg thiab shrinkage nyob rau hauv lub putty. Thaum putty dries tawm, nws tuaj yeem yooj yim tawg thiab rub tawm ntawm qhov chaw, ua rau tsis pom kev tsis zoo. Los ntawm kev tswj xyuas cov dej kom zoo, HEMC pab tiv thaiv cov putty los ntawm kev ziab sai heev thiab yog li txo qhov kev pheej hmoo ntawm kev tawg thiab shrinkage.

Zoo dua Adhesion: HEMC tuaj yeem pab txhim kho qhov adhesion ntawm putty rau saum npoo. Thaum putty qhuav dhau los yog tsis txaus hydrated, nws tuaj yeem ua tsis tiav, uas tuaj yeem ua rau nws tev tawm ntawm qhov chaw. Los ntawm kev txhim kho cov dej tuav cov khoom ntawm lub putty, HEMC tuaj yeem pab ua kom muaj kev ruaj khov thiab ruaj khov rau saum npoo.

Txhim kho Durability: Putty nrog cov dej tuav tau zoo tuaj yeem ua tau ntev dua li putty uas dries sai sai. Los ntawm kev tswj xyuas cov dej kom zoo, HEMC tuaj yeem pab txhim kho tag nrho cov kav ntev thiab lub neej ntev ntawm lub putty, txo qhov kev xav tau kev kho ntau zaus lossis kov-ups.

Tej yam yuav tsum tau xav txog thaum siv HEMC hauv Putty nrog dej zoo

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 nrog cov dej tuav tau zoo yuav nyob ntawm cov yam ntxwv xws li qhov xav tau sib xws, viscosity, thiab daim ntawv thov. Feem ntau, qhov 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 hmoov sib tov kom huv si kom paub meej tias HEMC 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 khaws dej kom zoo thiab txhim kho kev ua haujlwm. Txawm li cas los xij, tus nqi ntawm HEMC xav tau yuav txawv nyob ntawm seb hom putty siv.

Environmental Factors: Ib puag ncig yam xws li kub thiab av noo tuaj yeem cuam tshuam cov dej tuav cov khoom ntawm lub putty. Hauv cov huab cua ntub, putty tuaj yeem nqus dej noo los ntawm huab cua, uas tuaj yeem cuam tshuam rau nws qhov sib xws thiab kev ua haujlwm. Piv txwv li, nyob rau hauv qhuav tej yam kev mob, putty yuav poob noo noo sai heev
