Cellulose ether dej tuav nyhuv tso saib

Cellulose ether muaj cov dej tuav zoo.

Cellulose ether yog ib qho tshuaj ntxiv hauv cov tshuaj khib nyiab qhuav, uas ua lub luag haujlwm tseem ceeb heev.

Mortar nyob rau hauv cellulose ether yaj nyob rau hauv dej, vim hais tias lub nto active lub luag hauj lwm los xyuas kom meej cov gelled cov khoom zoo sib xws nyob rau hauv lub system, thiab cellulose ether raws li ib yam ntawm cov kev tiv thaiv colloid, "pob" cov khoom, thiab nyob rau hauv nws sab nrauv nto los tsim ib txheej. ntawm lubrication zaj duab xis, lub slurry system ruaj khov dua, thiab kuj txhim kho cov slurry nyob rau hauv lub mixing txheej txheem ntawm liquidity thiab kev tsim kho ntawm daim tawv nqaij yuav cia li zoo li.

Cellulose ether tov vim nws tus kheej molecular qauv cov yam ntxwv, kom cov dej nyob rau hauv mortar tsis yooj yim los plam, thiab nyob rau hauv ib tug muaj zog lub sij hawm maj mam tso tawm, muab mortar zoo tuav thiab workability.

Cov dej tuav ntawm cellulose ether yog ib qho tseem ceeb thiab cov ntaub ntawv qhia tau yooj yim, dej tuav yog hais txog cov dej khaws cia ntawm cov tshuaj khib nyiab tshiab ntawm hydrophobic substrate tom qab capillary ua.

Ntawm no nrog rau txoj kev sim yooj yim, tsuas yog qhia qhov faib kuv cellulose ether dej tuav nyhuv, tsuas yog saib oh!

Cellulose ether

Vim tias tsis muaj kev sib koom ua ke kev sim rau cov dej tuav ntawm cellulose ether nyob rau hauv lub teb chaws, cov tuam txhab tsim khoom feem ntau tsis muab cov kev ntsuas.

Tab sis txhawm rau ua kom yooj yim rau kev siv thiab kev ntsuam xyuas ntawm cov neeg siv khoom, ob qho kev tshaj lij cellulose ether dej tuav txoj hauv kev tau siv ntau hauv kev lag luam: txoj kev nqus thiab lim ntawv.

Yog tias koj xav tau cov ntaub ntawv no ua ib qho kev siv, thov hu rau peb kom paub meej kev sib txuas lus.

Peb lub tuam txhab cov hmoov txhuv nplej siab ether, yog hydroxypropyl hmoov txhuv nplej siab ether (HPS), ib yam ntawm cov nroj tsuag ntuj ua raw cov ntaub ntawv, tom qab kev hloov kho, cov tshuaj tiv thaiv etherified, thiab tom qab ntawd tshuaj tsuag kom qhuav thiab dawb hmoov zoo, tsis muaj plasticizer.

Lub cev muaj zog: hmoov dawb, zoo fluidity, zoo dej solubility, nws cov kua aqueous pob tshab tsis muaj xim, zoo ice melting stability.

Daim ntawv thov nta:

1. Lub mortar yuav thickened sai;

2. Nruab nrab viscosity, nrog rau qee yam dej tuav;

3. Kev siv me me, ntau npaum li cas tuaj yeem ua tiav cov txiaj ntsig zoo;

4. Txhim kho lub peev xwm los tiv thaiv dai ntawm cov ntaub ntawv;

5. Txhim kho kev ua haujlwm ntawm mortar, kom kev tsim kho kom zoo dua;

6. Txuas lub sijhawm qhib ntawm mortar.

Khoom siv:

Cement-raws li mortar: dej resistant putty rau sab hauv thiab sab nrauv phab ntsa, nplaum plaster mortar, ceramic pobzeb kua nplaum, sib koom tus neeg sawv cev, inorganic rwb thaiv tsev mortar;

Gypsum base mortar: gypsum putty, gypsum bonding mortar, gypsum plastering mortar, gypsum caulking mortar, gypsum hluav taws mortar, gypsum rwb thaiv tsev mortar;

Nruab nrab putty.
