Hypromellose-masonry mortartxhim khu lub adhesion rau saum npoo ntawm masonry thiab cov dej tuav lub peev xwm, yog li nce lub zog ntawm lub mortar. Txhim kho lubricity thiab plasticity ua rau kev txhim kho kev tsim kho, kev siv yooj yim dua, txuag lub sij hawm, thiab txhim kho cov nqi zoo.
Hypromellose - kev tuav dej zoontawm daim ntawv sib koom ua ke tuaj yeem ua kom lub sijhawm txias thiab txhim kho kev ua haujlwm. Lubricity siab ua rau daim ntawv thov yooj yim dua thiab smoother. Tsis tas li ntawd txhim kho qhov kev tiv thaiv shrinkage thiab anti-cracking, zoo txhim kho qhov zoo ntawm qhov chaw. Muab kev ntxhib los mos thiab kev ntxhib los mos, thiab ua rau cov khoom sib txuas ua kom muaj zog.
Hypromellose-cement-raws li plastering txhim khu kev sib xws, ua rau plastering yooj yim rau kev thov, thiab txhim kho kev tiv thaiv rau ntsug ntws. Txhim khu fluidity thiab pumpability los txhim kho efficiency. Cov qauv siv hluav taws xob muaj qhov zoo ntawm kev tuav dej siab, ua kom lub sijhawm ua haujlwm ntawm cov mortar, txhim kho kev ua haujlwm zoo, thiab pab tsim kom muaj lub zog zoo ntawm cov mortar thaum lub sij hawm solidification. Tsis tas li ntawd, huab cua infiltration tuaj yeem tswj tau, yog li tshem tawm cov micro-cracks ntawm txheej txheej, tsim kom zoo nkauj du nto.
HPMC- plaster, plaster thiab gypsum khoom
Txhim kho qhov sib xws, ua kom cov plaster yooj yim dua coated, thaum txhim kho lub peev xwm los tiv thaiv ntsug ntws los txhim kho cov kua dej thiab nqus dej. Yog li txhawm rau txhim kho kev ua haujlwm zoo. Nws kuj muaj qhov zoo ntawm kev tuav dej siab, tuaj yeem txuas ntxiv lub sijhawm ua haujlwm ntawm mortar, thiab tsim kom muaj zog txhua yam thaum lub sij hawm solidification. Los ntawm kev tswj qhov sib xws ntawm mortar uniform, tsim cov txheej txheem zoo.
Hypromellose - dej-raws li cov xim thiab cov xim tshem tawm kom ntev lub txee lub neej los ntawm kev tiv thaiv cov nag lossis daus. Nws yog sib xws nrog lwm yam khoom thiab muaj biostability siab. Kev tawg sai sai yam tsis muaj agglomerates pab kom yooj yim rau kev sib xyaw. Muab kev txav mus los zoo, suav nrog tsis tshua muaj txaws thiab qib zoo kom ntseeg tau tias qhov zoo ntawm qhov chaw tiav thiab tiv thaiv cov xim poob. Txhim kho cov viscosity ntawm cov xim pleev xim rau dej thiab cov organic solvent xim Remover, kom cov xim tshem tawm yuav tsis ntws tawm ntawm qhov chaw ntawm lub workpiece.
Hypromellose-ceramic tile adhesives ua rau nws yooj yim rau kev sib xyaw cov khoom xyaw qhuav tsis tsim cov clumps, yog li txuag lub sijhawm ua haujlwm thiab txhim kho kev ua haujlwm thiab txo cov nqi los ntawm kev ua kom sai thiab siv tau zoo dua. Kev ua haujlwm ntawm cov nplaum nplaum yog txhim kho los ntawm lub sijhawm txias. Ua tiav cov nyhuv adhesion. Self-leveling hypromellose muab viscosity thiab yuav siv tau raws li ib tug anti-sedimentation additive. Txhim kho kev txav mus los thiab twj tso kua mis, yog li txhim kho qhov ua tau zoo ntawm kev tso hauv pem teb. Tswj dej tuav, yog li ntawd zoo heev txo qhov tawg thiab shrinkage.
Hypromellose-formed pob zeb los xij txhim kho cov txheej txheem ntawm cov khoom extruded, muab siab zog thiab lubricity. Txhim kho ntub lub zog thiab daim ntawv adhesion tom qab extrusion.
Yam tseem ceeb uas cuam tshuam cov dej tuav ntawm hypromellose HPMC cov khoom
Cov dej khaws cia ntawm hypromelloseHPMC cov khoomfeem ntau cuam tshuam los ntawm cov hauv qab no:
1.Cellulose ether HPMC homogeneously reacted nrog HPMC, methoxy, hydroxypropyl homogeneously faib, siab retention tus nqi.
2.Cellulose ether HPMC thermogel kub, thermogel kub, siab dej tuav tus nqi, ntawm qhov tsis tooj, tsis tshua muaj dej tuav tus nqi.
3.Thaum lub viscosity ntawm cellulose ether HPMC nce, cov dej tuav tus nqi kuj nce, thiab thaum lub viscosity mus txog ib tug tej degree, cov dej tuav tus nqi nce maj mam.
4.Qhov ntau ntawm cov cellulose ether HPMC tau ntxiv, qhov siab dua cov dej tuav tau, thiab qhov zoo ntawm cov dej tuav tau zoo dua. Nyob rau hauv thaj tsam ntawm 0.25-0.6%, cov dej tuav tau nce sai nrog qhov nce ntawm qhov sib ntxiv.
