HydroxyPropyyl methylulose (HPMC) thiab hydroxyethyl cellulose (HEC) feem ntau siv nyob rau hauv tsev ua haujlwm thiab cov khoom muaj nuj nqis. Nov yog qee qhov ntawm lawv cov haujlwm tseem ceeb hauv cov ntaub ntawv hauv tsev:

1. Dej khaws cia: HPMC thiab HPMC thiab HECMC thiab kev ua kom tiv thaiv cov chaw sawv cev kom ceev ceev ntawm cov tshuaj khib nyiab xws li cov tshuaj khib thiab plaster thaum lub tshuaj kho. Los ntawm kev sib sau ua yeeb yaj kiab ib ncig ntawm cov pajas, lawv txo cov dej evaporation, tso cai rau kev txhim kho ntev thiab txhim kho kev txhim kho lub zog.
2. Kev Ua Haujlwm Txhim Kho: HPMC thiab HPMC thiab HPMC thiab HPMC thiab HPMC thiab HPMC thiab HP txhim kho kev ua haujlwm ntawm cov khoom siv Maas-based los ntawm kev ua kom muaj zog thiab txo cov kev sib txhuam ntawm cov khoom sib txhuam. Qhov no ua tau cov kev sib kis tau, cohesenived, thiab yooj yim ntawm cov ntawv sau ua ke, ris tsho, thiab cov nplaum sib xyaw thiab ntau yam kev ua tiav.
3. Thickening thiab rheology tswj: HPMC thiab HECT ua haujlwm raws li cov tuab tuab thiab rhuaology modifiers hauv cov ntaub ntawv hauv tsev, kho lawv cov hom phiaj viscosity thiab ntws yam ntxwv. Lawv pab tiv thaiv kev tawm tsam thiab sib cais ntawm cov khoom xyaw rau hauv cov khoom xyaw, kom muaj txiaj ntsig homogeneous faib thiab ruaj khov.
4. Adhesion qib: HPMC thiab HPMC thiab HPMC thiab HPMC thiab HPMC thiab HPMC thiab HPMC thiab HPMC thiab HPMC thiab HPOR ntawm cov khoom noj kom meej rau substrates xws li pob zeb ua, masonry, thiab vuas. Los ntawm kev sib sau ua ib zaj duab xis nyias nyob rau sab nraud ntawm ntug kev, lawv tau txhim kho cov nyiaj sib deev thiab cov khoom sib xyaw, txo qhov kev pheej hmoo ntawm kev cuam tshuam lossis tsis ua tiav.
5. Shrinkage txo: HECC thiab HECC thiab HECC thiab kev pab cuam kom txo cov khoom siv casent-basing los ntawm kev txhim kho lawv qhov chaw ntxhov siab sab hauv. Lawv ua tiav qhov no los ntawm kev txhim kho cov particle palcle, txo cov dej poob, thiab tswj hwm tus nqi ntawm kev haus dej, ua rau muaj kev ua tiav.
6. Teem sijhawm lub sijhawm tswj: HPMC thiab HPMC thiab HPMC thiab HPMC thiab HPMC thiab HPMC thiab HPMC thiab HPMC thiab HPMC thiab HPMC thiab cov khoom siv raws li cov khoom noj kom haum thiab yuag thiab hnyav. Lawv muab cov peev txheej hauv kev tsim kho thiab pub rau kev tswj tau zoo dua qub ntawm cov txheej txheem kev teeb tsa, haum rau ntau yam kev xav tau ua haujlwm thiab ib puag ncig.
7. Txhim kho durability: HEC ua pab txhawb rau cov ntaub ntawv tsim tsev ntawm kev ua kom zoo rau cov khoom siv kom khov, noo noo, thiab nres tsheb. Lawv pab kom txo qis tawg, spalling, thiab detheration, ntev lub neej pabcuam kev tsim kho.

HydroxyPropyyl methylulose (HPMC) thiab hydroxyethyl cellulose (HEC) Ua haujlwm tseem ceeb hauv kev txhim kho cov haujlwm, kev ua haujlwm, durability, thiab tag nrho cov khoom siv hauv tsev. Lawv tej yam kev ua haujlwm ntau ntau ua rau lawv muaj txiaj ntsig zoo ntxiv rau ntau yam ntawm kev siv kev thov siv vaj tsev kawm, kom ua tiav qhov ua tiav thiab kev ua haujlwm ntev ntawm ntau yam kev tsim kho ntau yam.
