Hydroxypropyl methylcellulose rau phab ntsa txau!

Hydroxypropyl methylcellulose cov khoom siv rau kev tsim kho yog dav siv los txhim kho kev ua haujlwm ntawm cov khoom siv hydraulic, xws li cov cement thiab gypsum. Hauv cov cement-based mortars, nws txhim kho cov dej tuav, ncua sij hawm kho thiab qhib lub sijhawm, thiab txo qis qis.

ib. Kev tuav dej

Hydroxypropyl methylcellulose rau kev tsim kho kom tsis txhob ya raws los ntawm kev nkag mus rau hauv phab ntsa. Cov dej tsim nyog nyob twj ywm hauv cov mortar, kom cov cement muaj sij hawm ntev dua los hydrate. Cov dej tuav yog proportional rau viscosity ntawm cellulose ether tov nyob rau hauv lub mortar. Qhov siab dua qhov viscosity, qhov dej tuav tau zoo dua. Thaum cov dej molecules nce, cov dej tuav tau qis. Vim hais tias rau tib tus nqi ntawm kev tsim kho tshwj xeeb hydroxypropyl methylcellulose tov, qhov nce hauv dej txhais tau tias txo qis hauv viscosity. Kev txhim kho ntawm kev tuav dej yuav ua rau ncua sij hawm kho ntawm lub mortar tau tsim.

b. Txhim kho kev tsim kho

Daim ntawv thov ntawm hydroxypropyl methylcellulose HPMC tuaj yeem txhim kho kev tsim kho ntawm mortar.

c. Lubricating muaj peev xwm

Txhua tus neeg ua haujlwm huab cua nkag mus ua cov neeg ua dej ntub dej los ntawm kev txo qis qhov nro thiab pab cov nplua nyob rau hauv mortar kom tawg thaum tov nrog dej.

d. Anti-sagging

Ib qho zoo sag-resistant mortar txhais tau hais tias thaum siv rau hauv cov khaubncaws sab nraud povtseg, tsis muaj kev phom sij ntawm sag lossis downward flow. Sag kuj tuaj yeem txhim kho los ntawm kev tsim kho tshwj xeeb hydroxypropyl methylcellulose. Kev tsim kho tshwj xeeb hydroxypropyl methylcellulose uas tsim los ntawm Shandong Chuangyao Company tuaj yeem muab cov khoom zoo dua los tiv thaiv sagging ntawm mortar.

e. Cov ntsiab lus npuas

Cov huab cua npuas cov ntsiab lus ua rau zoo dua mortar tawm los thiab ua haujlwm tau zoo, txo qis kev tawg. Nws kuj txo qis tus nqi siv, ua rau "liquefaction" tshwm sim. Cov ntsiab lus ntawm huab cua npuas feem ntau yog nyob ntawm lub sijhawm nplawm.

Qhov zoo ntawm hydroxypropyl methylcellulose hauv kev tsim cov khoom siv hauv tsev:

Hydroxypropyl methylcellulose muaj nws cov khoom tshwj xeeb hauv kev siv cov khoom siv hauv tsev, los ntawm kev sib xyaw kom tawg mus rau kev tsim kho, raws li hauv qab no:

Composite thiab configuration:

1. Nws yog ib qho yooj yim los sib tov nrog cov hmoov qhuav qhuav.

2. Nws muaj cov yam ntxwv ntawm cov dej txias dispersion.

3. Ncua cov khoom siv tau zoo, ua kom sib tov smoother thiab zoo ib yam.

Dispersion thiab mixing:

1. Cov mis qhuav qhuav uas muaj hydroxypropyl methylcellulose tuaj yeem sib xyaw nrog dej yooj yim.

2. Ceev ceev kom tau raws li qhov xav tau.

3. Kev tawg ntawm cellulose ether yog sai dua thiab tsis muaj pob.

Kev tsim kho hauv online:

1. Txhim kho lubricity thiab plasticity los txhim kho machinability thiab ua cov khoom tsim kom yooj yim dua thiab sai dua.

2. Txhim kho cov yam ntxwv tuav dej thiab ua kom lub sijhawm ua haujlwm ntev.

3. Pab tiv thaiv qhov ntws ntsug ntawm mortar, mortar thiab vuas. Ua kom lub sijhawm txias thiab txhim kho kev ua haujlwm.

Kev ua tiav tiav thiab zoo li:

1. Txhim kho lub zog sib txuas ntawm cov nplais nplaum.

2. Txhim khu kev tiv thaiv kev sib tsoo thiab kev tiv thaiv kev sib tsoo ntawm cov tshuaj khib thiab pawg thawj coj sib koom ua ke.

3. Txhim kho cov ntsiab lus huab cua hauv mortar thiab txo qhov muaj peev xwm ntawm cov kab nrib pleb.

4. Txhim kho cov tsos ntawm cov khoom tiav.

5. Nws tuaj yeem txhim kho qhov ntws ntsug ntawm cov nplais nplaum.

Hydroxypropyl methylcellulose (HPMC) yog non-ionic cellulose ether ua los ntawm cov paj rwb ntshiab los ntawm ntau cov txheej txheem tshuaj. Hydroxypropylmethylcellulose (HPMC) yog ib qho tsis muaj ntxhiab, tsis qab, tsis muaj tshuaj lom cov hmoov dawb uas tuaj yeem yaj hauv dej txias los tsim cov kua nplaum pob tshab. Nws muaj cov yam ntxwv ntawm thickening, khi, dispersing, emulsifying, zaj duab xis-forming, suspending, adsorbing, gelling, nto active, tswj cov dej noo thiab tiv thaiv colloid.
