Hydroxylopylenecorean (HPMC) yog cov khoom siv ntau yam polymer uas tuaj yeem nrhiav kev siv dav hauv kev tsim kho kev lag luam.Nws feem ntau yog siv los ua additives rau ntau yam khoom siv hauv tsev los txhim kho nws cov kev ua tau zoo thiab cov yam ntxwv.
1. Pob zeb:
Pob zeb yog cov khoom siv hauv tsev, thiab qhov sib ntxiv ntawm HPMC tuaj yeem cuam tshuam rau nws cov yam ntxwv.HPMC ua raws li cov dej noo thiab thickener hauv cov pob zeb sib tov.Qhov no yuav txhim kho kev ua haujlwm thiab kev sib sau ua ke, uas yooj yim rau kev tso thiab ua tiav.HPMC lub peev xwm noo noo pab tiv thaiv cov pob zeb los ntawm qhuav ntxov ntxov, yog li txo qhov kev pheej hmoo ntawm cov kab nrib pleb thiab txhim kho tag nrho cov kav ntev.
HPMC tuaj yeem txhim kho lub zog tseem ceeb ntawm cov cement matrix thiab agglomeration, uas yuav pab txhim kho kev ua haujlwm zoo.Lub polymer kuj ua raws li cov kua-kawm hloov pauv, cuam tshuam rau viscosity thiab ntws ntawm cov pob zeb sib xyaw.Qhov no tshwj xeeb tshaj yog muaj txiaj ntsig zoo rau daim ntawv thov kev txhim kho tus kheej lossis kev ua kom muaj zog siab.
2. Khoom siv:
Nyob rau hauv mortar formula, HPMC muaj ntau lub hom phiaj.Zoo ib yam li nws lub luag haujlwm hauv kev ua vaj tse, nws txhim kho kev ua tau zoo thiab kev tshwj tseg, yog li txhim kho qhov txo qis hauv drooping drooping thaum lub sijhawm ua ntawv thov.Cov nyhuv thickening ntawm HPMC yog qhov tseem ceeb tshwj xeeb hauv kev siv ntsug, xws li rendering thiab plastering, uas yog ib qho tseem ceeb kom tswj tau qhov sib xws.
Lub HPMC nyob rau hauv lub mortar formula pab zoo qhib lub sij hawm, thiab ncua sij hawm ua ntej lub mortar teeb.Qhov no yog qhov muaj txiaj ntsig zoo hauv kev tsim kho uas yuav tsum tau txuas ntxiv, xws li cov phiaj xwm loj lossis kev sib tw ib puag ncig.
3. Gypsum:
Hauv kev siv gypsum, HPMC ua lub luag haujlwm tseem ceeb hauv kev txhim kho cov khoom siv.Lub polymer txhim khu cov txheej txheem thiab adhesion ntawm cov av nkos, uas txhawb nqa smoother thiab ntau cov noodles.HPMC cov yam ntxwv khaws cia cov dej noo tuaj yeem tiv thaiv cov av nkos kom qhuav sai, yog li txo qhov muaj peev xwm tawg thiab ua kom ntseeg tau tias cov khoom kawg muaj zog dua.
HPMC pab txo qhov sib txawv ntawm huab cua hauv plaster matrix, yog li txhim kho lub zog thiab kav ntev.Qhov no yog tshwj xeeb tshaj yog zoo nyob rau hauv daim ntawv thov ntawm sab nraud gypsum, vim hais tias raug rau huab cua phem tej yam kev mob yuav ua rau kev ncaj ncees ntawm cov av nkos lub sij hawm.
4. Txheej:
HPMC yog siv dav hauv kev npaj cov txheej txheem, nrog rau cov xim thiab cov nplaum.Hauv dej-raws li xim, HPMC ua raws li thickening thiab stabilizer los tiv thaiv kev sib hais haum thiab xyuas kom meej tias lub txee lub neej ntawm tag nrho cov khoom zoo ib yam.Cov polymer kuj tseem txhim kho daim ntawv thov cov yam ntxwv ntawm cov xim, xws li kev yooj yim ntawm kev siv thiab kev siv nruas.
Nyob rau hauv cov mis formula, HPMC txhim khu cov khoom adhesion zog thiab viscosity.Nws cov dej tuav lub peev xwm pab qhib lub sijhawm ntev, kom nws tuaj yeem ntub cov substrate zoo dua thiab txhim kho qhov adhesion.Tsis tas li ntawd, HPMC pab tswj cov yam ntxwv ntws ntawm cov txheej txheem kom ntseeg tau tias qhov tseeb ntws thiab ruaj khov hauv cov txheej txheem thov.
Hydroxylopyamium cellulose muaj kev cuam tshuam loj heev rau ntau yam khoom siv hauv tsev xws li pob zeb, mortar, gypsum thiab coatings.Nws cov yam ntxwv ua haujlwm ntau yam yog dej-muaj dej, thickening thiab ntws cov neeg ua haujlwm, ua rau nws muaj txiaj ntsig zoo hauv kev tsim kho kev lag luam.Cov nyiaj tau los ntawm HPMC hauv cov ntaub ntawv no tuaj yeem txhim kho kev ua tau zoo, adhesion thiab durability, thiab thaum kawg txhim kho tag nrho cov kev ua tau zoo thiab lub neej ntawm cov qauv tsim.Nrog rau kev nce qib ntawm qhov chaw thev naus laus zis thiab kev tshawb fawb, kev siv HPMC tuaj yeem txhim kho txuas ntxiv mus, uas yuav pab tau ntau dua kev ua haujlwm ruaj khov thiab elastic.
