Yog vim li cas vim li cas hydroxypropyl methylcellulose yog dav siv

Hydroxypropyl methylcellulose yog tam sim no siv rau txhua qhov chaw ntawm lub neej. Dab tsi ntawm raw khoom yog nws?

Los ntawm qhov pom ntawm lub cev, hydroxypropyl methylcellulose yog non-ionic cellulose ether, dawb hmoov, thiab tsis muaj saj. Hauv kev tsim kho kev lag luam, nws tuaj yeem siv los ua tus neeg saib xyuas dej thiab retarder rau cement mortar kom cov mortar pumpable.

Cov hauv qab no yog qee yam khoom ntawm hydroxypropyl methylcellulose:

1. Nrog nws zoo stability, emulsions thiab dej-soluble resin coatings yuav siv tau raws li emulsifiers, stabilizers thiab thickeners, thiab lwm yam., thiaj li yuav ua rau cov txheej hnav-resistant thiab nplaum, thiab cia ruaj PH nqi.

2. Nws muaj dej tuav. Lub luag haujlwm tseem ceeb ntawm hydroxypropyl methylcellulose putty hmoov yog tias kuv tuaj yeem khaws dej thiab ua lub luag haujlwm ntawm lubrication thiab adhesion. Nws txhim kho kev ua haujlwm ntawm lub ntsws thiab nws tus kheej-skinning kom tsis txhob muaj qhov tshwm sim ntawm hmoov.

3. Nws muaj zoo dispersibility nyob rau hauv hluavtaws resins. Raws li tus neeg saib xyuas kev tiv thaiv, hydroxypropyl methylcellulose tuaj yeem ua lub luag haujlwm tseem ceeb hauv kev tiv thaiv kev sib sau ntawm cov khoom siv polymer thiab txhim kho qhov ruaj khov ntawm cov khoom tawg.

Ntxiv rau cov khoom no, hydroxypropyl methylcellulose, nrog rau cov thickening zoo, muaj zog adhesion, kev tsim kho thiab lwm yam ntxwv, nws tuaj yeem pom tias nws cov kev ua tau zoo heev. Vim tias cov haujlwm no, hydroxypropyl methylcellulose tau siv dav hauv ntau lub lag luam, xws li kev tsim kho, kev lag luam txheej, thiab lwm yam, thiab hydroxypropyl methylcellulose yog qhov tseem ceeb.
