Lub luag hauj lwm ntawm Hydroxypropyl Methylcellulose nyob rau hauv ntub mortar

Hydroxypropyl methylcellulose (HPMC) feem ntau yog siv los ua ib qho tshuaj ntxiv hauv cov tshuaj khib nyiab los txhim kho lawv cov khoom thiab kev ua haujlwm. HPMC yog cov dej-soluble polymer uas tau los ntawm cellulose thiab feem ntau yog siv los ua cov thickener, binder, thiab emulsifier hauv ntau hom kev siv.

Hauv cov khib nyiab ntub dej, HPMC tuaj yeem pab txhim kho kev ua haujlwm, txo qhov nqus dej, thiab txhim kho adhesion. Thaum ntxiv rau qhov sib tov, nws tuaj yeem muab kev ntxhib los mos thiab sib xws, ua kom yooj yim rau kev thov thiab sib kis. HPMC tseem tuaj yeem txhim kho kev sib koom ua ke ntawm cov tshuaj khib nyiab, tiv thaiv nws los ntawm kev sib cais lossis tawg thaum kho.

Tsis tas li ntawd, HPMC tuaj yeem txhim kho qhov ua haujlwm ntev thiab lub zog ntawm cov mortar ntub dej. Nws tuaj yeem txhim kho lub zog sib txuas ntawm cov mortar thiab substrate, ua rau nws tiv taus dej nkag thiab yaig. Qhov no yog qhov tseem ceeb tshwj xeeb tshaj yog nyob rau hauv cov ntawv thov uas cov tshuaj khib yuav raug cuam tshuam rau ib puag ncig hnyav, xws li hauv kev siv sab nrauv lossis hauv av.

Zuag qhia tag nrho, qhov sib ntxiv ntawm HPMC rau cov khib nyiab ntub dej tuaj yeem ua rau muaj kev ua haujlwm tau zoo, adhesion, lub zog, thiab kav ntev.
