Hydroxypropyl hmoov txhuv nplej siab rau mortar yog hloov pauv cov hmoov txhuv nplej siab uas feem ntau siv los ua cov khoom ntxiv hauv cov cement-based mortar formulations.Cov hmoov txhuv nplej siab no yog tshuaj hloov kho kom suav nrog cov pab pawg hydroxypropyl, uas txhim kho nws cov kev ua tau zoo thiab kev ua haujlwm hauv kev siv tshuaj khib nyiab.Hydroxypropyl hmoov txhuv nplej siab pab txhawb rau ntau yam khoom hauv mortar, txhim kho kev ua haujlwm, adhesion, thiab tuav dej.
Nov yog qee cov yam ntxwv tseem ceeb thiab kev siv cov hmoov txhuv nplej siab hydroxypropyl rau mortar:
Yam ntxwv:
1. Dej Solubility:
- Hydroxypropyl hmoov txhuv nplej siab feem ntau yog dej-soluble, tso cai rau kev sib koom ua ke yooj yim rau hauv mortar formulations.
2. Hloov Cov Qauv:
- Kev hloov kho hydroxypropyl suav nrog kev qhia txog cov pab pawg hydroxypropyl rau cov hmoov txhuv nplej siab, hloov nws cov qauv.
3. Thickening Properties:
- Hydroxypropyl starch ua raws li tus neeg sawv cev thickening nyob rau hauv mortar, cuam tshuam nws cov viscosity thiab pab txhawb rau kev ruaj ntseg ntawm cov formulation.
4. Txhim kho Adhesion:
- Qhov sib ntxiv ntawm hydroxypropyl hmoov txhuv nplej siab txhim kho cov khoom adhesion ntawm mortar, ua rau txhim kho kev sib raug zoo rau substrates.
5. Kev tuav dej:
- Hydroxypropyl hmoov txhuv nplej siab pab hauv dej tuav hauv cov tshuaj khib nyiab, tiv thaiv kom qhuav ntau dhau thiab txhim kho kev ua haujlwm ntawm cov khoom.
Kev siv hauv mortar:
1. Kev Txhim Kho Kev Ua Haujlwm:
- Hydroxypropyl hmoov txhuv nplej siab txhim kho kev ua haujlwm ntawm mortar los ntawm kev cuam tshuam nws cov khoom rheological.Qhov no yog tshwj xeeb tshaj yog zoo nyob rau hauv daim ntawv thov xws li plastering thiab rendering.
2. Kev Txhim Kho Adhesion:
- Hauv cov pobzeb nplaum thiab lwm cov tshuaj mortar, hydroxypropyl starch txhim kho adhesion, txhawb kev sib raug zoo ntawm cov tshuaj khib thiab cov substrate.
3. Kev tuav dej:
- Cov dej tuav cov khoom ntawm hydroxypropyl starch yog ib qho tseem ceeb hauv kev siv tshuaj khib nyiab.Lawv pab tiv thaiv kom qhuav sai ntawm mortar, tso cai rau ncua sij hawm ua hauj lwm thiab txhim kho curing.
4. Txo Sagging:
- Hydroxypropyl hmoov txhuv nplej siab pab txo qis sagging nyob rau hauv daim ntawv thov ntsug, xws li thaum siv mortar rau phab ntsa.Qhov no pab tswj qhov xav tau thickness thiab uniformity.
5. Txhim khu kev sib raug zoo:
- Lub thickening zog ntawm hydroxypropyl hmoov txhuv nplej siab pab txhawb rau tag nrho cov zoo sib xws thiab kev ntxhib los mos ntawm mortar, ua rau nws yooj yim mus lis thiab thov.
Nws yog ib qho tseem ceeb uas yuav tsum nco ntsoov tias qhov kev ua tau zoo ntawm hydroxypropyl hmoov txhuv nplej siab hauv kev siv tshuaj khib nyiab tuaj yeem nyob ntawm cov khoom xws li nws qhov hnyav molecular, qib ntawm kev hloov pauv, thiab tag nrho cov qauv ntawm cov mortar.Cov neeg tsim khoom feem ntau muab cov lus qhia thiab cov ntaub ntawv qhia kev los pab rau kev siv cov hmoov txhuv nplej siab hydroxypropyl hauv mortar formulations.
