Hydroxypropyl methylcellulose ua dab tsi?

Hauv kev siv cov khoom siv hauv tsev,Hydroxypropyl methylcellulose yog tsim los ntawm cov tshuajyog ib qho khoom siv hauv tsev ntau dua, thiab hydroxypropyl methylcellulose yog siv dav hauv kev lag luam thiab muaj ntau hom. Hydroxypropyl methylcellulose tuaj yeem muab faib ua hom dej txias tam sim thiab kub yaj hom, dej txias instant HPMC tuaj yeem siv rau hauv cov hmoov putty, mortar, kua nplaum, kua xim thiab cov khoom siv tshuaj txhua hnub; Kub yaj HPMC feem ntau yog siv rau cov khoom siv hmoov qhuav, thiab sib tov ncaj qha nrog cov hmoov qhuav xws li cov hmoov putty thiab mortars rau ib daim ntawv thov.

Hydroxypropyl methylcellulose tuaj yeem siv dav los txhim kho kev ua haujlwm ntawm cov cement, gypsum thiab lwm yam khoom siv hauv tsev. Hauv cov cement mortar, nws tuaj yeem txhim kho cov dej tuav, ncua sij hawm kho thiab qhib lub sijhawm, thiab txo qhov tshwm sim ntawm qhov tshwm sim.

Hydroxypropyl methylcellulose tuaj yeem siv rau hauv kev sib xyaw thiab kev tsim cov khoom siv hauv tsev, thiab cov qauv sib xyaw qhuav tuaj yeem sib xyaw nrog dej sai thiab qhov xav tau sib xws tuaj yeem tau sai. Cellulose ether dissolves sai dua thiab tsis muaj agglomeration, propylmethylcellulose tuaj yeem sib xyaw nrog cov hmoov qhuav hauv cov khoom siv hauv tsev, nws muaj cov yam ntxwv ntawm dispersing hauv dej txias, uas tuaj yeem tshem tawm cov khoom zoo thiab ua kom cov khoom sib tov zoo dua thiab zoo ib yam.

Tsis tas li ntawd, nws tuaj yeem txhim kho lubricity thiab plasticity, nce kev ua haujlwm, ua kom cov khoom tsim tau yooj yim dua, ntxiv dag zog rau cov dej tuav dej, ua kom lub sijhawm ua haujlwm ntev, pab tiv thaiv qhov ntws ntsug ntawm mortar, mortar thiab vuas, thiab txuas ntxiv lub sijhawm txias, los txhawb kev ua haujlwm.

Hydroxypropyl methylcellulose yog sivTxhim kho lub zog sib txuas ntawm cov nplais nplaum, txhim kho qhov kev sib tsoo ntawm cov tshuaj khib thiab cov nplaum ntoo, tsis yog tsuas yog ua kom cov huab cua nyob rau hauv lub mortar, tab sis kuj zoo heev txo qhov muaj peev xwm ntawm kev tawg, thiab kuj txhim kho cov tsos ntawm cov khoom thiab txhim khu kev tiv thaiv kev ua haujlwm ntawm cov nplais nplaum.
