Hydroxypropyl Methyl Cellulose HPMC
1. Nws muaj kev ruaj ntseg rau cov kua qaub thiab alkali, thiab nws cov kua aqueous yog ruaj khov heev hauv pH = 2 ~ 12 ntau yam.Caustic dej qab zib thiab txiv qaub dej tsis muaj txiaj ntsig zoo rau nws qhov kev ua tau zoo, tab sis alkali tuaj yeem ua kom nws cov kuab tshuaj sai dua thiab txhim kho cov viscosity me ntsis.
2. HPMCyog ib qho dej-retaining tus neeg saib xyuas zoo rauqhuav mortarsystem, uas tuaj yeem txo tus nqi ntawm mortar secretion thiab stratification, txhim kho cov cohesiveness ntawm mortar, zoo inhibit qhov tsim ntawm mortar yas tawg, thiab txo cov mortar yas cracking Performance index.
3, nws yog non-ionic thiab non-polymeric electrolyte, uas yog ruaj khov heev nyob rau hauv aqueous daws ntawm hlau ntsev thiab organic electrolytes, thiab yuav muab ntxiv rau lub tsev cov ntaub ntawv rau lub sij hawm ntev los xyuas kom meej tias nws durability yog zoo dua.
4, kev ua haujlwm ntawm cov mortar tau zoo dua qub, cov mortar zoo li muaj "roj", tuaj yeem ua rau phab ntsa sib koom ua ke tag nrho, du nto, kom cov mortar thiab lub hauv paus daim ntawv cog lus ruaj khov, thiab tuaj yeem ua haujlwm ntev.
Kev tuav dej
Lub realization ntawm sab hauv curing yog conducive rau kev txhim kho lub sij hawm ntev lub zog, inhibition ntawm los ntshav, kev tiv thaiv ntawm mortar sib hais haum, lub shrinkage thiab kev txhim kho ntawm mortar cracking kuj.
Thickening
Tiv thaiv kev sib cais, txhim kho qhov sib xws ntawm cov tshuaj khib nyiab, txhim kho cov ntaub ntawv ntub dej, thiab txhim kho kev ua haujlwm los tiv thaiv dai.
Cua nkag
Txhim kho kev ua haujlwm ntawm mortar.Nrog rau qhov siab dua qhov viscosity ntawm cellulose, qhov ntev ntawm cov saw hlau molecular, qhov pom tseeb ntawm huab cua entraining nyhuv.
Ncua coagulation
Koom tes nrog kev tuav dej kom txuas ntxiv lub sijhawm qhib ntawm mortar
Hydroxypropyl Starch ether
1. Cov ntsiab lus hydroxypropyl ntau dua hauv cov hmoov txhuv nplej siab ether muab lub zog ruaj khov hydrophilicity, tig dej dawb rau hauv cov dej khi, uas ua lub luag haujlwm khaws dej zoo.
2. Cov hmoov txhuv nplej siab ethers nrog cov ntsiab lus sib txawv hydroxypropyl muaj peev xwm sib txawv los pab cov cellulose khaws cov dej ntawm tib qhov ntau npaum li cas.
3. Kev hloov pauv ntawm pawg hydroxypropyl ua rau kom qhov o ntawm cov dej thiab compresses qhov chaw rau particle ntws, yog li ua tiav cov nyhuv ntawm thickening thiab viscosity nce.
Thixotropic lubrication
Cov hmoov txhuv nplej siab ether tau tawg sai sai hauv cov tshuaj khib nyiab, hloov cov rheology ntawm mortar thiab muab nws thixotropy.Thaum siv cov quab yuam sab nraud, qhov viscosity ntawm cov tshuaj khib yuav raug txo, ua kom muaj kev tsim kho zoo thiab siv tau, thiab muab thixotropy rau nws.Nws muaj kev xav zoo.Thaum lub zog sab nraud raug tshem tawm, qhov viscosity nce ntxiv, muab cov tshuaj khib nyiab zoo rau sagging.Ntawm cov hmoov putty, nws muaj qhov zoo ntawm kev txhim kho lub ci ci ntawm cov roj putty thiab polishing brightness.
Txhawb dej tuav nyhuv
Starch ether nws tus kheej muaj hydrophilic zog vim lub luag hauj lwm ntawm hydroxypropyl pawg nyob rau hauv lub system.Thaum ua ke nrog cellulose los yog ntxiv rau hauv ib qho nyiaj rau hauv mortar, nws tuaj yeem ua kom cov dej khaws cia rau qee yam thiab txhim kho lub sijhawm ziab ntawm qhov chaw.
Anti-sag thiab anti-slip
Zoo heev anti-sag nyhuv thiab shaping nyhuv.
Redispersible polymer hmoov
1. Txhim kho kev ua haujlwm ntawm cov tshuaj khib nyiab.Redispersible hmoovr or RDPparticles yog dispersed nyob rau hauv lub system, muab lub system zoo fluidity thiab txhim kho lub workability thiab workability ntawm lub mortar.
2. Txhim kho qhov kev sib txuas ntawm lub mortar.Tom qab cov hmoov roj hmab tau tawg mus rau hauv zaj duab xis, cov inorganic thiab organic teeb meem nyob rau hauv mortar system yuav fused ua ke.Nws tuaj yeem xav txog tias cov cement thiab xuab zeb hauv lub mortar yog cov pob txha, thiab cov hmoov latex tsim cov ligaments.Lub cohesion nce, lub zog nce, thiab cov qauv hloov tau maj mam tsim.
3. Txhim kho huab cua tsis kam ntawm cov tshuaj khib.Freeze-thaw resistant latex hmoov yog ib qho thermoplastic resin nrog kev ua haujlwm zoo, uas tuaj yeem ua rau cov mortar los teb rau cov kev hloov pauv sab nraud hauv qhov txias thiab kub, tiv thaiv cov mortar los ntawm kev tawg vim qhov kub thiab txias.
4. Txhim kho lub zog flexural ntawm mortar.Cov polymer thiab cov cement slurry tsim ua kom zoo dua.Thaum cov kab nrib pleb tshwm sim los ntawm sab nraud quab yuam, cov polymer tuaj yeem cuam tshuam cov kab nrib pleb thiab inhibit qhov kev nthuav dav ntawm cov kab nrib pleb, yog li txhim kho cov pob txha toughness thiab deformability ntawm mortar.
