  • Muab los ntawm hmoov txhuv nplej siab, uas yog cov carbohydrate tau los ntawm ntau yam nroj tsuag.
  • Hloov kho los ntawm hydroxypropylation los txhim kho nws cov khoom.
• HPMC (Hydroxypropyl Methylcellulose):
  • Muab los ntawm cellulose, ib qho polymer ntuj pom nyob rau hauv cov phab ntsa cell ntawm cov nroj tsuag.
  • Hloov kho los ntawm hydroxypropylation thiab methylation kom ua tiav cov khoom xav tau.

2. Cov Khoom Siv Los Ntawm:

• HPSE:
  • Tau los ntawm cov hmoov txhuv nplej siab uas yog los ntawm cov nroj tsuag, xws li pob kws, qos yaj ywm, lossis tapioca.
• HPMC:
  • Muab los ntawm cov nroj tsuag cellulose, feem ntau yog ntoo pulp lossis paj rwb.

3. Kev yaj tau:

• HPSE:
  • Feem ntau qhia tau tias muaj kev yaj dej zoo, ua rau yooj yim tawg hauv cov dej ua cov qauv.
• HPMC:
  • Cov dej yaj heev, tsim cov tshuaj meej hauv dej.

4. Kev Ua Kub Kub:

• HPSE:
  • Qee cov hydroxypropyl starch ethers yuav ua rau pom cov khoom thermal gelation, qhov twg qhov viscosity ntawm cov tshuaj nce nrog rau qhov kub thiab txias.
• HPMC:
  • Feem ntau tsis qhia txog kev ua kom sov, thiab nws cov viscosity tseem ruaj khov thoob plaws ntau qhov kub thiab txias.

5. Cov Khoom Siv Ua Yeeb Yaj Kiab:

• HPSE:
  • Muaj peev xwm tsim cov yeeb yaj kiab uas muaj kev ywj pheej zoo thiab kev nplaum zoo.
• HPMC:
  • Qhia txog cov yam ntxwv ua zaj duab xis, pab txhawb kev sib txuas thiab kev sib koom ua ke hauv cov qauv tsim kho.

6. Lub Luag Haujlwm hauv Kev Tsim Kho:

• HPSE:
  • Siv rau hauv kev tsim kho vim nws cov khoom ua kom tuab, khaws dej, thiab nplaum. Nws tuaj yeem siv rau hauv cov khoom siv gypsum, cov xuab zeb, thiab cov nplaum.
• HPMC:
  • Siv dav hauv kev tsim kho vim nws lub luag haujlwm ua cov khoom ua kom tuab, cov neeg sawv cev khaws dej, thiab ua kom ua haujlwm tau zoo. Nws feem ntau pom muaj nyob rau hauv cov cement-based mortars, cov nplaum pobzeb, grouts, thiab lwm yam formulations.

7. Kev Sib Xws:

• HPSE:
  • Sib xws nrog ntau yam khoom siv thiab cov ntaub ntawv siv hauv kev tsim kho.
• HPMC:
  • Qhia tau tias muaj kev sib raug zoo nrog ntau yam ntaub ntawv siv hauv kev tsim kho thiab cov khoom ntxiv.

8. Lub Sijhawm Teem:

• HPSE:
  • Tej zaum yuav cuam tshuam rau lub sijhawm teeb tsa ntawm qee cov qauv tsim kho.
• HPMC:
  • Yuav cuam tshuam rau lub sijhawm teeb tsa ntawm cov mortar thiab lwm yam khoom cementitious.

9. Kev Hloov Tau Yooj Yim:

• HPSE:
  • Cov yeeb yaj kiab tsim los ntawm hydroxypropyl starch ethers feem ntau yuav yoog tau.
• HPMC:
  • Pab txhawb rau kev ywj pheej thiab kev tiv thaiv kev tawg hauv cov qauv tsim kho.

10. Cov Cheeb Tsam Thov:

• HPSE:
  • Pom muaj ntau yam khoom siv hauv kev tsim kho, suav nrog plaster, putty, thiab adhesive formulations.
• HPMC:
  • Feem ntau siv rau hauv cov cement-based mortars, vuas vov tsev, grouts, thiab lwm yam khoom siv hauv kev tsim kho.

Hauv kev xaus lus, thaum ob qho tib si Hydroxypropyl Starch Ether (HPSE) thiab Hydroxypropyl Methylcellulose (HPMC) ua haujlwm zoo sib xws hauv kev tsim kho, lawv cov keeb kwm tshuaj sib txawv, cov yam ntxwv solubility, thiab lwm yam khoom ua rau lawv haum rau ntau yam qauv thiab daim ntawv thov hauv kev lag luam tsev. Qhov kev xaiv ntawm lawv nyob ntawm qhov xav tau tshwj xeeb ntawm cov khoom siv tsim kho thiab cov yam ntxwv kev ua tau zoo xav tau.
