Qhov siab dua qhov clarity ntawm hydroxypropyl methyl cellulose, qhov zoo dua cov dej solubility. Cov yam ntxwv uas cuam tshuam rau cov dej solubility ntawm ntub cement mortar muaj xws li viscosity ntawm cellulose ether, tus nqi ntxiv, particle loj thiab daim ntawv thov kub. Qhov siab dua qhov viscosity ntawm cellulose ether, qhov zoo dua cov dej solubility. Viscosity yog qhov tseem ceeb parameter ntawm HPMC. Piv nrog rau tib yam khoom, lub viscosity ntsuas nyob rau hauv ntau txoj kev yog loj, me me los yog txawm ob zaug qhov deb. Yog li ntawd, nyob rau hauv cov nqe lus ntawm viscosity, nws yog ib qhov tsim nyog yuav tau ua nyob rau hauv tib lub xeem tus qauv. Xws li qhov kub thiab txias, lub cev muaj zog rotor, thiab lwm yam. Feem ntau hais lus, qhov siab dua qhov viscosity, qhov zoo dua qhov tseeb.
Hydroxypropyl methyl cellulose, hu ua "kev lag luam monosodium glutamate", yog dav siv. Hydroxypropyl methyl cellulose nws tus kheej kuj muaj ntau hom, uas tau muab faib ua dej txias instant hom thiab kub-melt hom. Dej txias instant HPMC yog siv dav, thiab tuaj yeem siv rau sab hauv phab ntsa putty hmoov, cement mortar, kua pleev xim tsev, tshuaj txhua hnub, thiab lwm yam. Thaum tshav kub kub soluble HPMC feem ntau yog siv rau cov khoom siv hmoov qhuav, uas ncaj qha tov nrog cov hmoov qhuav, xws li cov hmoov putty thiab mortar. Cov khoom siv dej txias tam sim no tsis zoo rau cov khoom kub-kua hauv cov dej tuav thiab cov khoom ruaj khov, yog li ntau hom yuav tsum tau xaiv raws li kev siv sib txawv.
Txawm li cas los xij, qhov siab dua qhov viscosity, qhov siab dua HPMC cov ntsiab lus, thiab qis dua solubility ntawm HPMC. Qhov no muaj kev cuam tshuam tsis zoo rau lub zog compressive thiab kev tsim kho cov yam ntxwv ntawm cov cement mortar. Qhov siab dua qhov viscosity, qhov pom tseeb dua cov nyhuv ntawm cov cement mortar. Txawm li cas los xij, sib txawv hauv av, qhov siab dua qhov viscosity yog, qhov siab dua qhov viscosity ntawm cement mortar yog. Ntxiv nrog rau daim ntawv thov, nws tseem yuav qhia cov ntaub ntawv ntawm tus kheej-nplaum riam thiab nws cov rhiab heev rau daim hlau. Tab sis nws tsis muaj txiaj ntsig los txhim kho lub zog compressive ntawm ntub cement mortar nws tus kheej.
Youngcel HPMC/MHEC Nws yog dav siv los ua Tus Neeg Sawv Cev Pabcuam 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.
