Hydroxypropyl Methyl Cellulose (HPMC)
1. Nws ruaj khov rau cov kua qaub thiab alkali, thiab nws cov kua aqueous yog ruaj khov nyob rau hauv thaj tsam ntawm pH = 2-12. Caustic soda thiab txiv qaub dej tsis muaj txiaj ntsig ntau rau nws qhov kev ua tau zoo, tab sis alkali tuaj yeem ua kom nws qhov kev sib cais thiab ua kom nws cov viscosity nce ntxiv.
2. HPMC yog cov khoom siv dej ua kom zoo rau cov hmoov qhuav mortar, uas tuaj yeem txo cov ntshav thiab cov txheej txheem ntawm cov tshuaj khib nyiab, txhim kho cov cohesion ntawm mortar, zoo inhibit qhov tsim ntawm cov yas tawg hauv mortar, thiab txo cov yas. cracking index ntawm mortar.
3. Nws yog ib qho uas tsis yog-ionic thiab tsis-polymeric electrolyte, uas yog ruaj khov heev nyob rau hauv aqueous tov uas muaj hlau ntsev thiab organic electrolytes, thiab yuav muab ntxiv rau lub tsev cov ntaub ntawv nyob rau hauv lub sij hawm ntev los xyuas kom meej nws durability.
4. Kev ua haujlwm ntawm cov mortar tau zoo tuaj. Lub mortar zoo li yog "roj", uas tuaj yeem ua rau cov pob qij txha ntawm phab ntsa tag nrho, du nto, ua rau cov mortar thiab lub hauv paus txheej daim ntawv cog lus ruaj khov, thiab ua kom lub sijhawm ua haujlwm ntev.
tuav dej
Ua tiav kev saib xyuas sab hauv, uas yog qhov tsim nyog rau kev txhim kho lub zog mus ntev
Inhibit los ntshav, tiv thaiv mortar los ntawm kev nyob thiab shrinking
Txhim kho qhov tawg tsis kam ntawm mortar.
ua kom tuab
Anti-segregation, txhim kho mortar uniformity
Txhim kho ntub daim ntawv cog lus lub zog thiab txhim kho sag kuj.
cua los ntshav
Txhim kho kev ua haujlwm ntawm mortar
Raws li cov viscosity ntawm cellulose ua siab dua thiab cov saw hlau molecular ntev, cov nyhuv huab cua nkag tau pom tseeb dua.
Retarding
Synergizes nrog dej tuav kom ntev lub sij hawm qhib ntawm lub mortar.
Hydroxypropyl hmoov txhuv nplej siab ether (HPS)
1. Cov ntsiab lus hydroxypropyl ntau dua hauv cov hmoov txhuv nplej siab ether endows lub kaw lus nrog ruaj khov hydrophilicity, ua dej dawb rau hauv cov dej khi thiab ua lub luag haujlwm zoo hauv dej tuav.
2. Cov hmoov txhuv nplej siab ethers nrog cov ntsiab lus hydroxypropyl sib txawv hauv lawv lub peev xwm los pab cellulose hauv dej tuav raws li qhov ntau npaum li cas.
3. Kev hloov pauv ntawm pawg hydroxypropyl ua rau muaj kev nthuav dav hauv dej thiab compresses qhov chaw ntws ntawm cov khoom, yog li ua kom cov viscosity thiab thickening nyhuv.
Thixotropic lubrication
Kev tawg sai sai ntawm cov hmoov txhuv nplej siab ether nyob rau hauv mortar system hloov lub rheology ntawm mortar thiab endows nws nrog thixotropy. Thaum siv lub zog sab nraud, qhov viscosity ntawm cov mortar yuav txo qis, ua kom muaj kev ua haujlwm zoo, kev siv zog, thiab khoom plig Thaum lub zog sab nraud raug tshem tawm, qhov viscosity nce ntxiv, yog li cov mortar muaj kev tiv thaiv zoo thiab tiv thaiv kev ua haujlwm, thiab nyob rau hauv cov hmoov putty, nws muaj qhov zoo ntawm kev txhim kho lub ci ci ntawm cov roj putty, polishing brightness, thiab lwm yam.
Qhov cuam tshuam ntawm kev pabcuam dej tuav
Vim yog cov nyhuv ntawm pawg hydroxypropyl hauv lub cev, hmoov txhuv nplej siab ether nws tus kheej muaj cov yam ntxwv hydrophilic. Thaum nws ua ke nrog cellulose los yog ntxiv rau qee qhov ntawm cov tshuaj khib, nws tuaj yeem ua kom cov dej khaws cia rau qee qhov thiab txhim kho lub sijhawm kom qhuav.
Anti-sag thiab anti-slip
Zoo heev anti-sagging nyhuv, shaping nyhuv
Redispersible latex hmoov
1. Txhim kho kev ua haujlwm ntawm mortar
Cov roj hmab hmoov cov khoom tawg tau tawg nyob rau hauv qhov system, endowing system nrog fluidity zoo, txhim kho kev ua haujlwm thiab kev ua haujlwm ntawm cov mortar.
2. Txhim kho qhov kev sib raug zoo thiab kev sib koom ua ke ntawm mortar
Tom qab cov hmoov roj hmab tau tawg mus rau hauv zaj duab xis, cov teeb meem tsis muaj sia thiab cov organic hauv cov tshuaj khib nyiab tau sib xyaw ua ke. Nws tuaj yeem xav txog tias cov cement xuab zeb nyob rau hauv mortar yog lub cev pob txha, thiab cov hmoov latex tsim cov ligament hauv nws, uas ua rau kom muaj kev sib koom ua ke thiab lub zog. tsim ib qho qauv yooj yim.
3. Txhim kho huab cua tsis kam thiab khov-thaw tsis kam ntawm mortar
Latex hmoov yog ib qho thermoplastic resin nrog kev ua haujlwm zoo, uas tuaj yeem ua rau cov mortar tiv nrog lwm qhov txias thiab kub hloov, thiab tiv thaiv kom tsis txhob mortar tawg vim qhov kub thiab txias.
4. Txhim kho lub zog flexural ntawm mortar
Qhov zoo ntawm polymer thiab cement paste ntxiv rau ib leeg. Thaum cov kab nrib pleb raug tsim los ntawm kev quab yuam sab nraud, cov polymer tuaj yeem hla cov kab nrib pleb thiab cuam tshuam cov kab nrib pleb los ntawm kev nthuav dav, kom cov pob txha toughness thiab deformability ntawm cov mortar zoo tuaj.
