Hydroxypropyl Methyl Cellulose

Cov lus piav qhia luv luv:

HPMC tsis muaj ntxhiab, tsis qab, tsis muaj tshuaj lom cellulose ethers khoom los ntawm ntuj hIgh molecular cellulose los ntawm cov txheej txheem tshuaj lom neeg thiab ua tiav.Nws yog cov hmoov dawb nrog dej zoo solubility. Nws muaj qhov ua tuab, nplaum, ua paug, emulsifying, zaj duab xis, tshem tawm, adsorption, tso kua roj, thiab cov xim ua kom zoo nkauj ntawm kev ua haujlwm saum npoo thiab tswj cov dej noo muaj nuj nqi ect.

Hydroxypropyl methyl cellulose yog nonionic cellulose ether uas ua los ntawm cov paj rwb kom huv los ntawm cov txheej txheem etherification. Nws lub ntsiab kev ua tau zoo yog raws li hauv qab no:

1. HPMC yog cov hmoov dawb dawb lossis daj me ntsis. ntxhiab tsw, tsis muaj tshuaj lom

2. HPMC tuaj yeem sai sai hauv cov dej txias los tsim cov tshuaj pob tshab; Vim hais tias nws muaj qee qhov ntawm hydrophobic methoxy pab pawg, nws tuaj yeem yaj nyob hauv qee cov kuab tshuaj organic.

3. Cov viscosity ntawm HPMC aqueous tov yog qhov ruaj khov nyob rau hauv thaj tsam ntawm PH3.0-10.0. Thaum PH tus nqi tsawg dua 3 lossis ntau dua 10, viscosity yuav raug txo kom tsawg

4. Cov kua aqueous ntawm HPMC muaj cov kev ua haujlwm saum npoo, yog li nws muaj emulsification thiab tiv thaiv tus txheeb ze ruaj khov ntawm cov colloid

5. Kev siv dej kub ntxhua thiab txuag kev ua kom zoo thaum lub sijhawm npaj ua rau cov hmoov av tsawg

6. HPMC yog hydrophilic, ntxiv rau tshuaj khib, gypsum, xim thiab lwm yam khoom los ua lub luag dej siab kom ruaj

7. HPMC muaj zoo mildew tsis kam thiab zoo viscosity stability nyob rau hauv ntev cia

8. HPMC tuaj yeem txo cov txhuam kev sib txhuam thiab txhim kho lubricity ntawm kev tsim kho

9. HPMC tuaj yeem tsim lub zog thiab yob pob tshab ntawv nrog roj zoo thiab ester tsis kam

Daim ntawv thov:

1. Sab hauv thiab sab nrauv phab ntsa putty

Cov dej ceev cov cuab yeej ntawm HPMC ua rau cov hmoov tsis zoo yuav tsis tawg vim tias kom qhuav sai tom qab kev tsim kho, txhim kho lub zog tom qab ua tawv tawv.Thaum tib lub sij hawm tseem ua si lub luag haujlwm hauv kev txhim kho daim ntawv cog lus

2. Lub kaw lus sab nrauv phab ntsa rwb thaiv tsev

Kev ntxiv ntawm HPMC tuaj yeem txhim kho qhov kev sib zog thiab kev sib luag ntawm cov tshuaj khib thiab txhim kho kev ua haujlwm

3. Sib xyaw tshuaj khib

HPMC dej zoo tuav, tuaj yeem siv sijhawm ntev dua, tiv thaiv cov pobzeb ceramic kom poob dej sai sai ua rau poob, txhim kho kev sib zog thiab shear lub zog

4. gypsum base plastering thiab khoom lag luam

Qhov kev tawm tsam ntawm dai ntawm HPMC tuaj yeem tshem tawm kev txhim kho tsev thiab thov txheej txheej tuab

5. Mechanical txau plastering

HPMC tuaj yeem txhim kho qhov kev npliag ntawm cov tshuaj khib, pab txhawb lub twj tso kua mis hloov, zam kev sib thiav tshuaj thiab cov kav dej txhaws

6. Maas extruded ntawv (cov ntsa ntsa yooj)

HPMC tuaj yeem txhim kho cov nplaum nplaum ntawm cov ntawv gypsum tom qab kev ua kom tiav, txhim kho cov nyiaj kom sib zog thiab kev ua kom zoo, thiab ua kom lub zog

7. Tus kheej qheb

Tsis tshua muaj viscosity HPMC muaj peev xwm tiv taus nag lossis daus thiab txhim kho qhov ntws ntawm pob zeb.Its dej tuav cia tiv thaiv kev ua kom tawg thiab ntsws
