Hydroxypropyl methyl cellulose (HPMC luv luv) muaj cov cuab yeej thickening zoo heev thiab tuaj yeem siv los ua tus neeg sawv cev zoo tshaj plaws rau cov pob zeb. Yav dhau los, cov khoom siv no yog cov khoom siv tshuaj zoo hauv cov khoom siv luv luv hauv Suav teb, nrog tus nqi siab. Vim muaj ntau yam laj thawj, nws daim ntawv thov hauv Suav teb kev tsim kho kev lag luam raug txwv.
Nyob rau hauv xyoo tas los no, nrog rau kev txhim kho txuas ntxiv ntawm sab nrauv phab ntsa thermal rwb thaiv tsev thev naus laus zis, kev nce qib ntawm cellulose ntau lawm technology, thiab cov yam ntxwv zoo ntawm HPMC nws tus kheej, HPMC tau siv dav hauv kev tsim kho kev lag luam. Hauv kev teeb tsa lub sijhawm ntsuas, lub sijhawm teeb tsa ntawm cov pob zeb feem ntau cuam tshuam nrog lub sijhawm teeb tsa ntawm cov cement, thiab cov sib sau ua ke tsis tshua muaj kev cuam tshuam. Yog li ntawd, lub sijhawm teem sijhawm ntawm mortar tuaj yeem siv los hloov qhov cuam tshuam ntawm HPMC ntawm lub sijhawm teeb tsa ntawm cov dej hauv qab dej uas tsis muaj qhov sib xyaw ua ke. Txij li thaum lub sijhawm teeb tsa ntawm mortar cuam tshuam los ntawm cov dej cement piv thiab cement xuab zeb piv
Rau kev cuam tshuam ntawm HPMC ntawm lub sijhawm teem sijhawm ntawm mortar, nws yog ib qho tsim nyog los kho cov dej cement piv thiab cement xuab zeb piv ntawm mortar. thiab lub sijhawm teeb tsa ntawm lub mortar nce nrog qhov nce ntawm HPMC. Nrog tib tus nqi ntawm HPMC, lub sijhawm teeb tsa ntawm lub mortar tsim nyob rau hauv dej yog ntev tshaj qhov tsim nyob rau hauv huab cua.
Qhov ntev molecular chains ntawm HPMC yuav nyiam ib leeg, ua rau HPMC molecules intertwine los tsim ib tug network qauv, thiab qhwv cov cement thiab sib tov dej. Raws li HPMC tsim cov qauv network zoo ib yam li zaj duab xis thiab qhwv cov cement, nws tuaj yeem tiv thaiv kom tsis txhob muaj dej hauv cov tshuaj khib nyiab thiab cuam tshuam lossis ua kom cov cement hydration. Hauv kev kuaj ntshav, qhov tshwm sim los ntshav ntawm mortar zoo ib yam li cov pob zeb, uas yuav ua rau muaj kev sib haum xeeb loj ntawm kev sib sau ua ke, nce cov dej cement piv ntawm cov txheej txheem saum toj kawg nkaus slurry, ua rau cov txheej saum toj kawg nkaus slurry shrink zoo heev nyob rau hauv thaum ntxov theem, txawm tawg. , thiab lub zog ntawm slurry nto yog qhov tsis muaj zog. Nws tuaj yeem pom los ntawm qhov kev sim uas thaum cov ntsiab lus siab dua 0.5%, tsis muaj qhov tshwm sim los ntshav. Qhov no yog vim hais tias thaum HPMC tov rau hauv mortar, HPMC muaj zaj duab xis-tsim thiab reticular qauv, nrog rau cov adsorption ntawm hydroxyl ntawm cov saw ntev ntawm macromolecule, uas ua rau cov cement thiab sib tov dej nyob rau hauv mortar daim ntawv flocculent, kom ruaj khov qauv. mortar. Thaum HPMC ntxiv rau hauv mortar, ntau cov npuas me me ywj siab yuav raug tsim. Cov npuas no yuav sib npaug sib npaug hauv cov tshuaj khib nyiab thiab cuam tshuam qhov kev tso tawm ntawm cov khoom sib xyaw. Qhov kev ua tau zoo ntawm HPMC no muaj kev cuam tshuam zoo rau cov khoom siv cement, thiab feem ntau yog siv los npaj cov cement-based composites tshiab xws li mortar qhuav thiab polymer mortar, kom lawv muaj dej zoo thiab cov yas tuav.
Kev ntsuas dej ntawm mortar muaj qhov cuam tshuam zoo rau cov dej xav tau ntawm mortar thaum tus nqi ntawm HPMC tsawg heev.
Youngcel HPMC / MHEC yog dav siv los ua Tshuaj Pab Pawg rau Pobzeb Adhesive, Cement Plaster, Qhuav mix mortar, Phab ntsa putty, Txheej, Detergent thiab lwm yam.Thiab peb tuaj yeem muab koj tus nqi qis tshaj thiab zoo tshaj plaws.
Peb cov khoom yog nrov nyob rau hauv Egypt, Russia, South Africa, Middle East, qaib ntxhw, Nyab Laj, Fabkis, Ltalis, Singapore, Bangladesh, Indonesia, South America thiab hais txog. Ua tsaug ua ntej thiab txais tos hu rau.
