Starch ether (tseem hu ua polymer lubricant)

Lub tswv yim: Ib hom uas tsis yog-ionic starch npaj los ntawm etherification cov tshuaj tiv thaiv ntawm propylene oxide thiab starch nyob rau hauv alkaline tej yam kev mob, kuj hu ua starch ether. Cov khoom siv raw yog tapioca starch. Ntawm lawv, cov ntsiab lus hydroxypropyl yog 25%, uas yog anti-thixotropic. Vim nws tsis tshua muaj viscosity, siab hydrophilicity, zoo fluidity, tsis muaj zog retrogradation thiab siab stability, nws yog dav siv nyob rau hauv kev tsim kho thiab kho kom zoo nkauj kev lag luam, xws li siv cov hmoov qhuav, plaster, sib koom ua ke nplaum thiab lwm yam nruab nrab thiab alkaline composite cov ntaub ntawv, txhim kho lub sab hauv. qauv ntawm cov khoom, thiab muaj kev sib raug zoo nrog cov additives nyob rau hauv nws, yog li ntawd cov khoom yog ntau resistant rau qhuav cracking, anti-sag, thiab txhim kho workability thiab kev tsim kho kev ua tau zoo.

Qhov tsos: dawb hmoov

yam ntxwv:

1. Zoo heev ceev thickening peev xwm: nruab nrab viscosity, siab dej tuav;

2. Cov koob tshuaj me me, thiab qhov ntau npaum li cas tuaj yeem ua tiav cov txiaj ntsig siab;

3. Txhim kho lub peev xwm los tiv thaiv sag ntawm cov khoom nws tus kheej;

4. Nws muaj lubricity zoo, uas tuaj yeem txhim kho kev ua haujlwm ntawm cov khoom siv thiab ua rau kev ua haujlwm smoother.

Standard ntim: 25kg

siv:

Hloov cov hmoov txhuv nplej siab ether yog siv rau hauv kev tsim kho, feem ntau yog rau thickening thiab anti-sagging, thiab cellulose ether yog tsuas yog rau cov dej tuav, yog li cov hmoov txhuv nplej siab ether yog siv ua ke nrog cellulose ether;

Nws tuaj yeem ua kom tuab thiab khaws cov dej, tsim cov txiaj ntsig zoo (raws li cov qauv, txo tus nqi ntawm HPMC li ntawm 30% thiab hloov nrog cov hmoov txhuv nplej siab ether kom nce cov khoom lag luam)

Los ntawm kev ntsuam xyuas, nws tau txiav txim siab tias nws yog ib qho kev xaiv zoo dua los ntxiv cov roj nplua nyeem rau sab nrauv phab ntsa putty nyob rau hauv ib puag ncig ntawm qhov kub ntawm lub caij ntuj sov. Lub lubricant belongs rau lub polymer compound, thiab rheological lubricant yog tsuas yog tsom rau kev txhim kho kev tsim kho hauv cov cement-based system. Lub sijhawm qhib thiab ua haujlwm zoo ib yam. Ua kom muaj peev xwm ua haujlwm thiab sag tsis kam ntawm mortars, plasters, renders, plasters thiab adhesives thiab tiv thaiv delamination ntawm tus kheej-leveling cement. Qhov laj thawj rau kev tuav dej yog tias muaj ntau pawg hydrophilic ua haujlwm ntawm nws cov saw hlau molecular. Nyob rau hauv cov ntaub ntawv ntawm rov qab scraping thiab txheej, nws yuav tsis poob dej, muaj zoo heev dej tuav kev ua tau zoo, thiab muaj thickening thiab thixotropy nyob rau tib lub sij hawm, ua rau kev tsim kho smoother thiab muaj peev xwm hloov ib feem ntawm cellulose, tab sis nws cov nqi tsuas yog cellulose ether, thiab nws qhov ntau npaum li cas yog 0.5kg-1kg, yog cov khoom siv zoo heev, yog siv ua ke nrog cellulose ether, lignocellulose, thiab redispersible latex hmoov, cov nyhuv yuav zoo dua.
