Qhov no yog qhov tseem ceeb tshwj xeeb tshaj yog rau cov ntaub ntawv uas yuav tsum tau ua kom muaj kev sib tsoo siab, xws li cov dej khib nyiab thiab cov phab ntsa sab nrauv.
Txhim kho rheological zog
Hydroxypropyl hmoov txhuv nplej siab ether muaj cov khoom zoo rheological thiab tuaj yeem tswj cov dej kom tsim nyog thiab kev ua haujlwm ntawm cov khoom siv hauv tsev thaum tsim kho. Qhov no yog ib qho tseem ceeb tshwj xeeb tshaj yog rau cov khoom uas yuav tsum tau muaj fluidity zoo, xws li self-leveling mortars thiab tshuaj tsuag cov ntaub ntawv. Nws tuaj yeem txhim kho qhov flatness thiab nto tiav ntawm cov khoom, ua rau kev tsim kho zoo nkauj dua.
Txhim kho dej tsis kam thiab huab cua tsis kam
Hydroxypropyl hmoov txhuv nplej siab ether tuaj yeem txhim kho cov dej tsis kam thiab huab cua tsis kam ntawm cov khoom siv hauv tsev, tso cai rau lawv kom muaj kev ua tau zoo hauv qhov chaw ntub dej thiab huab cua huab cua. Qhov no yog ib qho tseem ceeb tshwj xeeb rau cov ntaub ntawv uas yuav tsum tau muaj huab cua tsis kam, xws li cov txheej txheem phab ntsa sab nrauv thiab cov kab hluav taws xob sab nrauv. Nws tuaj yeem txhim kho cov khoom siv tiv thaiv dej yaig thiab ua kom nws lub neej ua haujlwm ntev.
Daim ntawv thov piv txwv ntawm hydroxypropyl starch ether
Cov nplaum nplaum
Hauv cov nplais pobzeb nplaum, hydroxypropyl starch ether tuaj yeem txhim kho lub zog sib txuas thiab dej tuav ntawm cov khoom, ua rau cov vuas ceramic ua kom ruaj khov rau hauv substrate. Nyob rau tib lub sijhawm, nws tuaj yeem txhim kho kev tsim kho thiab tiv thaiv cov vuas los ntawm kev zawv zawg thaum siv.
Putty hmoov
Hauv cov hmoov putty, hydroxypropyl starch ether tuaj yeem txhim kho cov thickening thiab kev ua haujlwm ntawm cov khoom, ua rau kev tsim kho smoother. Nws kuj tseem tuaj yeem txhim kho qhov tawg tsis kam ntawm putty thiab txo qhov tawg.
Self-leveling mortar
Nyob rau hauv tus kheej-leveling mortar, hydroxypropyl starch ether tuaj yeem txhim kho cov dej ntws thiab kev ua haujlwm ntawm tus kheej ntawm cov khoom, ua rau kev tsim kho yooj yim dua thiab sai dua.
