Yuav ua li cas xaiv qhov zoo cellulose

(1) Hydroxypropyl methylcellulose (HPMC) muab faib ua hom zoo tib yam (kub-soluble hom) thiab dej txias instant hom:

Hom zoo tib yam, clumps hauv dej txias, tab sis tuaj yeem tawg sai sai hauv dej kub thiab ploj hauv dej kub. Thaum qhov kub thiab txias poob rau qee qhov kub, qhov viscosity yuav maj mam tshwm kom txog thaum nws tsim cov pob tshab viscous colloid. Yog vim li cas thiaj ntsib cov dej txias yog: cov hmoov cellulose sab nrauv ntsib cov dej txias, tam sim ntawd ua kua, thickens rau hauv pob tshab colloid, thiab cellulose sab hauv yog ib puag ncig los ntawm cov colloid ua ntej nws los rau hauv dej, thiab nws tseem nyob rau hauv cov hmoov. daim ntawv. , tab sis maj mam melts tam sim ntawd. Cov khoom lag luam ib txwm tsis tas yuav siv cov dej kub hauv cov ntawv thov, vim tias cov hmoov putty lossis mortar yog cov hmoov zoo. Tom qab qhuav sib tov, cellulose yog cais los ntawm lwm yam ntaub ntawv. Thaum nws ntsib dej, nws yuav sai sai thiab yuav tsis tsim ib pawg.

Cov khoom tam sim ntawd tawg sai sai thaum nws ntsib dej txias thiab ploj mus hauv dej. Lub sijhawm no, cov kua dej tsis muaj viscosity, vim tias HPMC tsuas yog tawg mus rau hauv dej yam tsis muaj kev sib cais tiag tiag. Los ntawm li 2 feeb, lub viscosity ntawm cov kua maj mam nce, tsim ib pob tshab viscous colloid.

(2) Cov peev txheej ntawm daim ntawv thov ntawm hom zoo tib yam thiab hom tam sim no: hom tam sim no tsuas yog siv cov kua nplaum, tshuaj pleev ib ce, thiab ntxhua khaub ncaws. Vim tias qhov chaw ntawm instant cellulose tau kho nrog dialdehyde, cov dej tuav thiab kev ruaj ntseg tsis zoo li cov khoom siv zoo tib yam. Yog li ntawd, nyob rau hauv qhuav hmoov xws li putty hmoov thiab mortar, peb pom zoo cov khoom zoo tib yam.

Yuav ua li cas xaiv qhov zoo viscosity ntawm cellulose:

1. Ua ntej ntawm tag nrho cov, peb yuav tsum to taub lub luag hauj lwm ntawm cellulose ether: dej tuav thiab thickening.
2. Kev lag luam feem ntau tuaj yeem hais 100,000 viscosity, 150,000 viscosity, thiab 200,000 viscosity. Cov kev ntsuas no txhais li cas? Dab tsi yog qhov cuam tshuam ntawm qhov sib txawv ntawm kev ntsuas ntawm cov khoom?

(1) Rau kev tuav dej
Cov dej tuav tau nce nrog qhov nce ntawm viscosity, tab sis raws li kev ua lag luam, thaum lub viscosity ntawm cellulose tshaj 100,000, cov dej tuav tau nce nrog cov viscosity.

(2) Rau thickening
Feem ntau hais lus, thaum cov ntsiab lus muaj txiaj ntsig zoo li qub, lub tsev loj dua, qhov ua tau zoo dua cov thickening. Qhov ntawd yog hais tias, siab viscosity yuav tsum muaj dej ntau, thiab cov dej tuav tsis tau hloov ntau.

3. Ntau lub tuam txhab siv qhov sib txawv, uas yog, cov mortars thiab cellulose ether specifications txawv, tab sis rau cov chaw tsim khoom me, nws yuav ua rau tus nqi nce. Ntau lub tsev me me tsuas yog siv ib qho fiber ntau yas ether rau kev siv dav dav, uas yog, qhov ntau npaum li cas sib txawv. ! Feem ntau, 100,000 units yog siv ntau tshaj plaws.

4. Feem ntau 200,000 viscosity yog siv rau kev sib tsoo mortar, thiab 100,000 kuj yog siv rau tus kheej-leveling, 100,000 rau tus kheej-leveling, thiab 80,000 rau plastering. Ntawm chav kawm, nws yog tsuas yog txiav txim siab los ntawm qhov zoo ntawm cov dej tuav. Peb tsis pom zoo kom cov neeg siv khoom siv siab viscosity. Piv txwv li, rau 200,000 units, qhov siab dua qhov viscosity ntawm cellulose ether, qhov tsis ruaj tsis khov, thiab muaj cov khoom cuav ntau dua. Qee cov neeg siv khoom qhia tias 20W cov khoom tiag yog nplaum dhau thiab kev tsim kho tsis zoo heev.

5. Cov dej tuav ntawm cellulose ether siv hauv mortar yog txawv ntawm cov dej tuav ntawm cellulose ether hauv kev sim. Txawm hais tias cov dej tuav ntawm cellulose ether nws tus kheej yog qhov zoo, nws tsis tau txhais hais tias cov nyhuv hauv mortar yog qhov tseeb, nws yog txiav txim siab los ntawm qhov ua tau zoo ntawm cov khoom ntxiv hauv cov mis, qhov sib ntxiv, thiab cov nyhuv sib xyaw cov khoom siv mortar qhuav. Nws yog qhov zoo tshaj plaws los siv rau ntawm phab ntsa kom pom cov nyhuv. Qhov no yog qhov tseeb!
