Tsis tas li ntawd, nws txhim khu cov khoom xws li tawg tsis kam, adhesion thiab durability ntawm cement, gypsum thiab mortar. Ib qho me me ntawm HPMC tuaj yeem txhim kho qhov zoo ntawm cov khoom siv hauv tsev, ua rau nws tsim nyog rau ntau yam kev siv.
Hauv kev lag luam kws tshuaj, HPMC feem ntau yog siv los ua ib qho kev sib khi, disintegrant thiab sustained-tso tus neeg saib xyuas hauv cov ntsiav tshuaj, tshuaj ntsiav, thiab granules. Raws li kev sib khi, HPMC nce lub zog ntawm cov ntsiav tshuaj thiab tiv thaiv nws ntawm kev tawg thaum tuav. Raws li ib tug disintegrant, HPMC pab cov ntsiav tshuaj yaj sai sai nyob rau hauv lub plab zom mov. Nws kuj yog siv los ua tus neeg saib xyuas kev tso tawm, muab lub sijhawm ntev ntawm kev tso tshuaj. Cov khoom no ua rau HPMC muaj ntau yam khoom xyaw rau kev lag luam kws tshuaj, pab txhim kho cov qauv tshiab, txhim kho kev ua raws li cov neeg mob thiab ua kom cov tshuaj muaj txiaj ntsig zoo.
Hauv kev lag luam khoom noj khoom haus, HPMC feem ntau yog siv los ua cov thickener, stabilizer thiab emulsifier nyob rau hauv ntau yam khoom xws li ice cream, yogurt thiab sauces. Nws muab ib qho kev ntxhib los mos, txhim kho qhov ncauj qhov ntswg, thiab tiv thaiv cov khoom xyaw los ntawm kev sib cais lossis kev daws teeb meem. Tsis tas li ntawd, nws nce lub txee lub neej ntawm cov khoom thiab txo cov kev xav tau ntawm preservatives. HPMC feem ntau siv hauv cov khoom noj uas tsis muaj calorie lossis cov rog tsawg vim tias nws tuaj yeem ua raws li cov teebmeem ntawm cov rog los ntawm kev muab cov creamy zoo nkauj yam tsis ntxiv calories ntxiv.
Sib nrug los ntawm nws txoj haujlwm tseem ceeb, HPMC muaj qee qhov zoo dua hauv kev lag luam sib txawv. Nws muaj kev nyab xeeb rau tib neeg noj, yooj yim soluble hauv dej, thiab tsis muaj saj los yog tsw. Nws tseem yog biodegradable thiab ib puag ncig tus phooj ywg, ua rau nws muaj kev xaiv ruaj khov rau ntau daim ntawv thov. Tsawg toxicity thiab hypoallergenicity ntawm HPMC ua rau nws muaj kev nyab xeeb muaj nyob rau hauv ntau yam khoom, nrog rau cov tshuaj pleev ib ce, detergents thiab xim.
Hauv kev xaus, HPMC raws li kev nkag mus rau hauv daim ntawv hmoov yog qhov tseem ceeb hauv ntau qhov kev lag luam xws li kev tsim kho, tshuaj thiab zaub mov. Nws cov khoom siv ntau yam ua rau nws muaj qhov tseem ceeb hauv cov khoom tshiab thiab kev tsim kho, txhim kho qhov zoo, sib xws thiab ua tau zoo ntawm cov khoom kawg. Nws txoj kev nyab xeeb, kev ruaj ntseg thiab biodegradability ua rau nws yog ib qho zoo tagnrho cov khoom siv rau ntau yam kev siv, pab txhawb kev tsim cov khoom tshiab tshiab.
