Gypsum-raws li cug cug yog qhov tseem ceeb tiv thaiv hauv kev tsim kho, siv rau ntau yam kev siv plastering, Masonry, thiab xov. Txhawm rau txhim kho nws cov kev ua tau zoo thiab cov khoom, cov ntxiv zoo li hydroxypropylench nrho (HPMC) feem ntau ua rau sib xyaw.
1. spintroduction rau gypsum-raws li kev cai sib xyaw ua kom qhuav:
Gypsum raws li kev sib xyaw ua ke yog kev sib xyaw ua ntej ua ntej, cov khoom siv tshuaj ntsuab (feem ntau yog gypsum), feem ntau yog gypsum), feem ntau yog gypsum), feem ntau yog gypsum), feem ntau yog gypsum), feem ntau yog gypsum), feem ntau yog gypsum), thiab qee zaum cov polymers. Thaum sib xyaw nrog dej ntawm lub chaw tsim kho, nws tsim cov tshuaj tiv thaiv ua haujlwm uas tuaj yeem thov ncaj qha rau ntau hom substrates. Clop cug muab ob peb qhov zoo dua kev ua khaub ncaws ntub sib xyaw ua ke, suav nrog kev yooj yim ntawm kev thov, thiab ua kom zoo zoo tib yam.
2.Cov kev sib ntxiv hauv Gypsum-raws li kev cai sib xyaw ua kom qhuav:
Cov ntxiv ua si lub luag haujlwm tseem ceeb hauv kev txhim kho kev ua haujlwm ntawm gypsum-raws li cug tov. Lawv tuaj yeem txhim kho kev ua haujlwm, cov nplaum, cov dej khaws cia, lub sijhawm teem sijhawm, thiab lub zog kho tshuab. Ib qho kev txuas ntxiv siv hauv cov kab hlau ua tiav yog hydroxypropyl methylulose (HPMC).
3.HydroxyPropyyl Methylcellulose (HPMC):
HPMC yog lub cellulose ether tau los ntawm cov cellulose ntuj. Nws yog ib qho siv nyob rau hauv cov ntaub ntawv tsim kho vim nws cov khoom siv dej zoo, ua kom muaj peev xwm ua kom tuab, thiab adhesion txhim kho. Hauv Gypsum-raws li qhuav cug, hpmc ua raws li kev kho siab rheology, txhim kho kev sib xws thiab ua haujlwm ntawm kev sib xyaw.
4. Croproperties ntawm HPMC:
Dej khaws cia: HPMC cov yeeb yaj kiab tiv thaiv ib ncig ntawm cov Maas hais, tiv thaiv cov dej evaporation sai. Qhov no ua kom muaj kev sib luag ntawm cov paasent ntawm cov cement, uas ua rau kev txhim kho lub zog ua kom muaj zog thiab txo cov nrib pleb.
Thickening: HPMC Thickens lub tshuaj khib, tiv thaiv sagging thiab ua kom cov ntsug ntsug sib npaug ntawm phab ntsa thiab qab nthab.
Adhesion: HPMC txhim kho cov nplaum ntawm lub tshuaj khib nyiab rau ntau yam substrates, suav nrog cov pob zeb ua, Masonry, thiab plasterboard.
Teem sijhawm: Los ntawm kev tswj hwm tus nqi ntawm kev tswj cov dej, HPMC tuaj yeem kho lub sijhawm kho ntawm lub tshuaj txig, tso cai rau lub sijhawm txaus rau kev thov thiab xov.
Txhim kho cov haujlwm ua haujlwm: HPMC imparts zoo dua ua haujlwm tau zoo rau lub tshuaj khib, ua kom nws yooj yim dua mus kis, trowel, thiab ua tiav.
5.Benefits ntawm HPMC hauv Gypsum-raws li CNC CUG:
Kev ua haujlwm tau zoo: HPMC txhim kho kev sib xyaw thiab muaj zog ntawm lub tshuaj khib, ua kom nws yooj yim rau kev thov thiab cov duab.
Txo cov dej shrinkage: los ntawm kev khaws dej hauv cov tshuaj khib, hpmc pab txo cov shrinkage cracks, ua rau ib qho smoother thiab ntau ruaj khov tiav.
Txhim kho cov nyiaj txhiv lub zog: cov nplaum nplaum ntawm HPMC txhawb kom HPMC txhawb kom cov tshuaj khib nyiab zoo ntawm cov tshuaj khib thiab substrate, ua kom muaj adhesion ntev-ntev.
Kev ua tau zoo ib yam: sib koom ua ke HPMC sawv daws cov yam ntxwv zoo nkauj thiab kev ua tau zoo ntawm lub coll batch rau batch.
Versatility: HPMC tuaj yeem siv rau hauv ntau cov qauv thiab cov ntawv thov, ua rau nws ntau yam ntxiv rau gypsum-raws li cugsum qhuav.
6. daimij ntawm gypsum-raws li qhuav cug nrog HPMC:
Plastering: HPMC-Modififififififify cug feem ntau siv rau sab hauv thiab sab nrauv plastering applications vim nws ua haujlwm tau zoo thiab kev ua haujlwm zoo.
Masonry: HPMC txhim kho txoj hlua khi lub zog ntawm cultad hauv Masonry kev tsim kho, txhim kho cov txheej txheem kev sib raug zoo tag nrho.
Xov: HPMC pab kom ua tiav txoj kev du thiab tsis zoo ua tiav ntawm cov phab ntsa thiab nthab, txhim kho lub tsev pheeb suab ntawm lub tsev.
Kho thiab Kev Kho Dua: HPMC-hloov tsa cov nyiaj txiag HPMC yog tsim nyog rau kev kho thiab kho cov phiaj xwm kho dua tshiab, muab cov nplaum kom zoo rau cov substrates zoo.
HydroxyPropyyl Metylcellulose (HPMC) yog qhov tseem ceeb ntxiv rau hauv Gypsum-raws li kev sib xyaw ua ke. Nws cov khoom tau txhim kho kev ua haujlwm, cov nplaum, thiab teeb tsa lub sijhawm, ua rau muaj kev ua tau zoo, thiab siv tau yooj yim. Nrog nws cov versatility thiab cov txiaj ntsig, HPMC ua si lub luag haujlwm tseem ceeb hauv kev xyaum tsim kho niaj hnub, ua rau muaj kev ua tau zoo thiab kev ua haujlwm ntev.
