Kev siv tseem ceeb thiab qhov sib txawv ntawm hydroxypropyl methylcellulose HPMC thiab hydroxyethyl cellulose HEC

Kev siv tseem ceeb thiab qhov sib txawv ntawm hydroxypropyl methylcellulose HPMC thiab hydroxyethyl cellulose HEC

Carboxymethyl cellulose, hydroxypropyl methyl cellulose, thiab hydroxyethyl cellulose nrog kev lag luam monosodium glutamate yog siv ntau tshaj plaws.Qhov nyuaj tshaj plaws kom paub qhov txawv ntawm peb hom cellulose no yog hydroxypropyl methylcellulose thiab hydroxyethyl cellulose.Hauv qab no peb yuav paub qhov txawv ntawm ob hom cellulose los ntawm kev siv thiab kev ua haujlwm.

Raws li cov tsis-ionic surfactant, hydroxyethyl cellulose muaj cov khoom nram qab no ntxiv rau kev ua haujlwm ntawm kev ncua, thickening, dispersing, floating, bonding, film forming, dej tuav thiab muab kev tiv thaiv colloid:

1. HEC nws tus kheej tsis yog-ionic thiab tuaj yeem ua ke nrog ntau yam ntawm lwm cov dej-soluble polymers, surfactants, thiab ntsev.Nws yog ib qho zoo heev colloidal thickener rau cov kev daws teeb meem uas muaj high-concentration electrolytes.

2. Piv nrog rau kev lees paub methyl cellulose thiab hydroxypropyl methyl cellulose, lub peev xwm dispersing ntawm HEC yog qhov phem tshaj, tab sis lub peev xwm tiv thaiv colloid yog qhov muaj zog tshaj.

3. Lub peev xwm tuav dej yog ob zaug siab dua li ntawm methyl cellulose, thiab nws muaj kev tswj xyuas zoo dua.

4. HEC yog soluble nyob rau hauv dej kub los yog dej txias, thiab tsis precipitate ntawm kub los yog boiling, uas ua rau nws muaj ib tug ntau yam ntawm solubility thiab viscosity yam ntxwv, thiab non-thermal gelation.

Kev siv HEC: feem ntau yog siv los ua cov thickener, tiv thaiv tus neeg sawv cev, nplaum, stabilizer thiab kev npaj ntawm emulsion, jelly, ointment, lotion, qhov muag pom tseeb.

Hydroxypropyl methylcellulose (HPMC) daim ntawv thov kev taw qhia:

1. Txheej kev lag luam: Nws yog siv los ua cov thickener, dispersant thiab stabilizer hauv kev lag luam txheej, thiab muaj kev sib raug zoo hauv dej los yog cov kuab tshuaj organic.Raws li cov xim tshem tawm.

2. Ceramic manufacturing kev lag luam: Nws yog dav siv los ua cov ntaub ntawv hauv kev tsim cov khoom siv ceramic.

3. Lwm tus: Cov khoom no kuj tau siv dav hauv cov tawv nqaij, cov khoom siv ntawv, cov txiv hmab txiv ntoo thiab zaub khaws cia thiab kev lag luam textile, thiab lwm yam.

4. Ink printing: Nws yog siv los ua cov thickener, dispersant thiab stabilizer hauv kev lag luam number case, thiab muaj kev sib raug zoo hauv dej lossis cov kuab tshuaj organic.

5. Yas: siv los ua tus neeg sawv cev tso tawm, softener, lubricant, thiab lwm yam.

6. Polyvinyl chloride: Nws yog siv los ua ib qho dispersant hauv kev tsim cov polyvinyl chloride, thiab nws yog tus neeg sawv cev tseem ceeb rau kev npaj PVC los ntawm kev ncua polymerization.tus

7. Kev tsim kho kev lag luam: Raws li tus neeg saib xyuas dej thiab retarder ntawm cov cement xuab zeb slurry, nws tuaj yeem ua rau cov mortar pumpable.Nyob rau hauv plaster, gypsum, putty hmoov los yog lwm yam ntaub ntawv hauv tsev raws li ib tug binder los txhim kho kis tau tus mob thiab ntev lub sij hawm ua hauj lwm.Nws tuaj yeem siv los ua cov nplais pobzeb, marble, kho kom zoo nkauj yas, muab tshuaj ntxiv, thiab tuaj yeem txo cov cement.Cov dej-tswj kev ua tau zoo ntawm HPMC tiv thaiv cov slurry los ntawm kev tawg vim ziab sai heev tom qab thov, thiab txhim kho lub zog tom qab hardening.
