cov khoom

Cov yam ntxwv ua haujlwm ntawm cov dispersants hauv dej tau piav qhia raws li nram no:
1, es tsis txhob siv ammonia thiab lwm yam alkaline tshuaj ua tus neutralizer, txo cov ntxhiab tsw ntawm ammonia, txhim kho qhov chaw tsim khoom thiab kev tsim kho.
2, cov tshuaj dispersant raws li dej tuaj yeem tswj tau tus nqi pH, txhim kho kev ua haujlwm ntawm cov khoom tuab thiab viscosity stability.
3. Txhim kho cov nyhuv dispersion ntawm pigment, txhim kho qhov hauv qab thiab rov qab coarse phenomenon ntawm pigment particles, txhim kho kev sib kis ntawm cov xim muab tshuaj thiab cov luster ntawm cov xim zaj duab xis
4, cov tshuaj dispersant raws li dej yog volatile, yuav tsis nyob hauv zaj duab xis ntev, tuaj yeem siv rau hauv cov txheej txheem ci ntsa iab, thiab muaj kev tiv thaiv dej zoo heev thiab kev txhuam tsis kam.
5, cov tshuaj dispersant raws li dej siv tau ua cov khoom ntxiv, txo cov viscosity ntawm shear, txhim kho qhov fluidity thiab leveling ntawm cov xim.
Cov tshuaj dispersant uas yog dej yog ib qho khoom siv tseem ceeb hauv kev lag luam txheej. Pab kom cov xim pleev xim thiab cov khoom sau sib xyaw ua ke. Ua kom cov txheej yooj yim tawg thiab sib xws. Tsis tas li ntawd, nws kuj ua lub luag haujlwm ua kom cov txheej du thiab du hauv cov txheej txheem tsim zaj duab xis.

Cov ntawv thov
Siv rau txheej, inorganic hmoov additive Cov khoom no yog cov hydroxyl acid dispersant siv rau hauv txhua hom xim latex, titanium dioxide, calcium carbonate, talcum hmoov, wollastonite, zinc oxide thiab lwm yam pigments siv feem ntau tau qhia cov nyhuv dispersion zoo. Nws kuj tseem siv tau rau hauv cov number case luam ntawv, ua ntawv, textile, kho dej thiab lwm yam lag luam.

Kev ua tau zoo
Cov txheej txheem, kev ruaj khov ntawm cov hmoov inorganic dispersion, nrog rau kev them polar, pab txhawb kev sib kis ntawm cov khoom siv kho tshuab

1. Kev piav qhia:
Dispersant yog ib hom tshuaj interfacial active uas muaj cov yam ntxwv hydrophilic thiab lipophilic sib txawv hauv molecule. Nws tuaj yeem sib npaug cov khoom khov thiab kua ntawm cov inorganic thiab organic pigments uas nyuaj rau yaj hauv kua, thiab tseem tiv thaiv kev sib xyaw thiab kev sib xyaw ntawm cov khoom me me los tsim cov amphiphilic reagents uas xav tau rau kev ncua ruaj khov.

2. Cov Haujlwm Tseem Ceeb thiab Cov Zoo:
A. Kev ua tau zoo ntawm kev sib kis kom tiv thaiv kev sib sau ua ke ntawm cov khoom ntim khoom;
B. Kev sib haum xeeb zoo nrog cov tshuaj resin thiab cov khoom sau; Kev ruaj khov thermal zoo;
C. Zoo fluidity thaum tsim cov txheej txheem; Tsis ua rau xim ploj;
D, tsis cuam tshuam rau kev ua tau zoo ntawm cov khoom; Tsis muaj tshuaj lom thiab pheej yig.

3. Cov teb thov:
Siv dav hauv kev tsim kho thiab cov xim pleev dej.

4. Kev khaws cia thiab ntim khoom:
A. Txhua yam emulsions/additives yog dej ua thiab tsis muaj kev pheej hmoo ntawm kev tawg thaum thauj mus los.
B. 200 kg/hlau/yas nruas.1000 kg/pallet.
C. Cov ntim khoom yooj ywm uas haum rau 20 ft thawv yog xaiv tau.
D. Cov khoom no yuav tsum khaws cia rau hauv qhov chaw txias thiab qhuav, tsis txhob muaj dej noo thiab los nag. Qhov kub cia yog 5 ~ 40 ℃, thiab lub sijhawm cia yog li 12 lub hlis.
