Kev siv cov mortar sib xyaw ua ke yog ib txoj hauv kev zoo los txhim kho qhov project zoo thiab kev tsim kho kom zoo; kev txhawb nqa thiab kev siv cov khoom sib xyaw ua ke yog qhov tsim nyog rau kev siv cov peev txheej, thiab yog ib qho tseem ceeb rau kev txhim kho kom ruaj khov thiab kev loj hlob ntawm kev lag luam ncig; Kev siv cov mortar sib xyaw ua ke tuaj yeem txo qhov kev ua haujlwm thib ob ntawm kev tsim vaj tsev, txhim kho qib ntawm kev tsim kho tshuab, txhim kho kev tsim kho, txo kev siv zog, thiab txo tag nrho lub zog siv ntawm lub tsev thaum txuas ntxiv txhim kho kev nplij siab ntawm lub neej. ib puag ncig.
Qhov tsim nyog daim ntawv thov ntawm mortar additives ua rau kev tsim kho ntawm cov khoom sib xyaw ua ke ua tau; cellulose HPMC nrog kev ua tau zoo tuaj yeem txhim kho kev tsim kho kev ua haujlwm, siv thiab txau cov tshuaj khib nyiab; nws lub peev xwm thickening tuaj yeem txhim kho qhov ntub dej ntawm cov khib nyiab ntub rau hauv lub hauv paus phab ntsa Wetting muaj peev xwm, yog li txhim kho lub zog ntawm cov tshuaj khib nyiab; tuaj yeem kho lub sijhawm qhib ntawm mortar; Cov dej tuav tau zoo heev, tuaj yeem txo qhov tshwm sim ntawm cov yas tawg ntawm mortar; ua kom hydration ntawm cov cement ntau dua, yog li txhim kho tag nrho cov txheej txheem lub zog. Raws li ib tug zoo mortar, cov mortar sib tov yuav tsum muaj kev tsim kho zoo: yooj yim rau kev sib tov, zoo wettability rau lub hauv paus phab ntsa, du thiab tsis lo rau riam, txaus lub sij hawm ua hauj lwm (me me tsis sib xws), yooj yim mus rau theem ntawm hardened mortar. yuav tsum muaj kev ua tau zoo ntawm lub zog thiab qhov tsos: tsim lub zog compressive, kev sib txuas lub zog nrog lub hauv paus phab ntsa, zoo durability, du nto, tsis muaj hollowing, tsis muaj cracking, thiab tsis muaj hmoov poob.
Cov nyhuv uas tus kheej-leveling mortar tuaj yeem ua tiav nrog cov viscosity tsawg HPMC cellulose ether:
1. Xyuas kom lub fluidity ntawm tus kheej-leveling mortar.
2. Txhim kho lub peev xwm kho tus kheej ntawm tus kheej-leveling mortar.
3. Pab tsim ib qho chaw du.
4. Txo shrinkage thiab txhim kho cov kabmob muaj peev xwm.
5. Txhim kho qhov adhesion thiab cohesion ntawm tus kheej-leveling mortar rau lub hauv paus nto.
