Vim muaj cov yam ntxwv xws li huab cua kub, av noo, cua siab, thiab cua ceev, qhov volatilization tus nqi ntawm noo noo nyob rau hauv gypsum-based khoom yuav raug cuam tshuam.
Yog li txawm hais tias nws yog nyob rau hauv gypsum-based leveling mortar, caulk, putty, lossis gypsum-based self-leveling, hydroxypropyl methylcellulose ether (HPMC) plays lub luag haujlwm tseem ceeb.
Kev tuav dej ntawm BAOSHUIXINGHPMC
Hydroxypropyl methylcellulose zoo heev (HPMC) tuaj yeem daws qhov teeb meem ntawm dej tuav hauv qhov kub thiab txias.
Nws cov methoxy thiab hydroxypropoxy pawg yog sib npaug sib npaug ntawm cov cellulose molecular saw, uas tuaj yeem txhim kho lub peev xwm ntawm oxygen atoms ntawm hydroxyl thiab ether bonds los koom nrog dej los tsim hydrogen bonds, ua dej dawb rau hauv cov dej khi, yog li tswj tau cov evaporation zoo. ntawm cov dej tshwm sim los ntawm huab cua kub kom ua tiav cov dej khaws cia siab.
Constructability ntawm SHIGONGXINGHPMC
Cov khoom raug xaiv cellulose ether tuaj yeem nkag mus rau hauv ntau yam khoom gypsum yam tsis muaj agglomeration, thiab tsis muaj kev cuam tshuam tsis zoo rau lub porosity ntawm cov khoom kho gypsum, yog li ua kom muaj kev ua pa ntawm cov khoom gypsum.
Nws muaj qee yam kev cuam tshuam tab sis tsis cuam tshuam rau kev loj hlob ntawm gypsum crystals;Nws ua kom muaj peev xwm sib txuas ntawm cov khoom siv rau lub hauv paus nto nrog qhov tsim nyog ntub adhesion, zoo heev txhim kho kev tsim kho ntawm cov khoom siv gypsum, thiab yooj yim rau kev sib kis tsis muaj cov cuab yeej nplaum.
Lubricity ntawm RUNHUAXINGHPMC
High-zoo hydroxypropyl methylcellulose tuaj yeem sib npaug thiab ua haujlwm zoo hauv cov cement mortar thiab gypsum-raws li cov khoom, thiab qhwv tag nrho cov khoom siv, thiab tsim cov yeeb yaj kiab ntub dej, thiab cov dej noo hauv lub hauv paus yuav maj mam yaj mus rau lub sijhawm ntev.tso tawm, thiab tau txais cov tshuaj tiv thaiv hydration nrog inorganic gelling cov ntaub ntawv, yog li ua kom lub zog sib txuas thiab compressive zog ntawm cov khoom.
