HPMC siv nyob rau hauvPhab ntsa Putty /Skim Coat

HPMC tuaj yeem muab faib ua: qib kev tsim kho, qib zaub mov thiab qib kho mob raws li kev siv. Tam sim noTuam Tshoj is qib kev tsim kho feem ntau, hauv chav tsev,Phab ntsa putty /Skim Coat dosage ntawmskim tsho hmoov loj heev. HPMC hmoov thiab ntau lwm cov khoom xyaw hmoov, tag nrho tov nrog rab, ces ntxiv dej kom yaj, lub sij hawm no HPMC yuav yaj, tab sis tsis agglomerate, vim hais tias txhua lub ces kaum me me, me ntsis HPMC hmoov, dej yuav sai sai yaj.Skim Coathmoov thiab mortar ntau lawm enterprise siv hom no ntau dua. Hydroxypropyl methyl cellulose (HPMC) yog siv los ua thickener thiab dej tuav tus neeg sawv cev hauv cov tshuaj khib nyiab.

Lub gel kub ntawm HPMC muaj feem xyuam rau cov ntsiab lus methoxyl, qis dua cov ntsiab lus methoxylnqes, qhov siab dua cov gel up. HPMC dej txias instant tov hom yog tom qab glyoxal nto kho, muab tso rau hauv dej txias sai sai dispersed, tab sis tsis tshua yaj, viscosity, yog yaj. Cov thermosoluble HPMC hom tsis tau raug kho nrog glyoxal. Tus nqi ntawm glyoxal yog loj, dispersion yog ceev, tab sis lub viscosity qeeb, tus nqi yog me me, ntawm qhov tsis tooj. HPMC tuaj yeem muab faib ua tam sim thiab kub soluble, cov khoom lag luam tam sim, hauv dej txias sai sai, ploj mus hauv dej, lub sijhawm no cov kua tsis muaj viscosity, vim HPMC tsuas yog dispersed hauv dej, tsis muaj kev sib cais tiag tiag. Txog 2 feeb, cov viscosity ntawm cov kua maj mam nce, tsim cov pob tshab viscous colloid. Thaum tshav kub kub soluble khoom, nyob rau hauv dej txias agglomeration, yuav nyob rau hauv dej kub, sai sai dispersed, ploj nyob rau hauv dej kub, kom txog rau thaum lub kub poob mus rau ib tug tej yam kub, viscosity maj mam tshwm, kom txog rau thaum lub tsim ntawm pob tshab viscous colloid. Thaum tshav kub kub soluble hom tsuas yog siv rau hauvSkim Coat thiab mortar, nyob rau hauv kua kua nplaum thiab txheej, tuaj yeem tshwm agglomeration tshwm sim, tsis tuaj yeem siv. Instant yaj qauv, daim ntawv thov Scope yog ob peb wider, nyob rau hauvSkim Coathmoov thiab mortar, thiab nyob rau hauv kua kua nplaum thiab txheej, tag nrho cov yuav siv tau, tsis muaj dab tsi taboo.

Cov txheej txheem hnyav ntawm kev tsim HPMC, yog ua los ntawm toluene, isopropyl cawv hnyav, yog tias ntxuav tsis zoo, yuav muaj qee qhov seem seem. daim ntawv thov ntawmSkim Coat  hmoov: qhov yuav tsum tau muaj qis dua, viscosity 100000, Nws yog ib qho tseem ceeb los tiv thaiv cov dej kom nyob ze. Daim ntawv thov mortar: siab dua, siab viscosity, 150000 kom zoo dua. Daim ntawv thov kua nplaum: qhov xav tau rau cov khoom lag luam tam sim, siab viscosity. HPMC nyob rau hauv qhov tseeb daim ntawv thov ntawm tus nqi, los ntawm huab cua puag ncig, kub, lub zos grey calcium zoo,Skim Coat formula thiab "cov neeg siv khoom xav tau ntawm qhov zoo" ntawm qhov sib txawv, thiab muaj qhov sib txawv. Hydroxypropyl methyl cellulose (HPMC) ntawm viscosity -Skim Coathmoov yog100000, qee qhov siab ntawm qhov yuav tsum tau ua hauv mortar, xav tau 150 txhiab lub peev xwm siv. Tsis tas li ntawd, HPMC lub luag haujlwm tseem ceeb yog khaws cov dej, ua raws li cov thickening. HauvSkim Coat, tsuav yog cov dej tuav tau zoo, cov viscosity tsawg (7-80000), nws kuj tseem ua tau, tau kawg, qhov viscosity loj dua, cov txheeb ze dej tuav tau zoo dua, thaum cov viscosity ntau dua 100000, qhov viscosity ntawm dej tuav tsis ntau; Hydroxypropyl cov ntsiab lus yog siab, dej tuav feem ntau zoo dua. Viscosity, dej tuav, kuj zoo dua, thiab viscosity, nyob rau hauv cov cement mortar yog zoo dua siv.

HPMC hauvSkim Coat, thickening, dej tuav thiab kev tsim kho ntawm peb txoj haujlwm. Tsis koom nrog kev tawm tsam. Qhov ua rau lub npuas tuaj yeem yog dej ntau dhau, kuj tuaj yeem yog hauv qab tsis qhuav, nyob rau sab saum toj ntawm ib txheej ntawm scraping, kuj yooj yim rau npuas. HPMC hauv cov nyhuv thickening ntawmSkim Coat: cellulose tuaj yeem thickened rau ncua kev kawm ntawv, kom cov kev daws teeb meem tseem niaj hnub nce thiab nqis lub luag hauj lwm ntawm anti-flow dai. HPMC dej tuav cov nyhuv hauvSkim Coat: uaSkim Coat qhuav maj mam, auxiliary grey calcium tshuaj tiv thaiv nyob rau hauv qhov kev txiav txim ntawm dej. HPMC hauvSkim Coat Kev tsim kho lub luag haujlwm: cellulose lubrication, tuaj yeem uaSkim Coat muaj kev tsim kho zoo. HPMC tsis koom nrog cov tshuaj tiv thaiv kab mob, tab sis tsuas yog ua lub luag haujlwm txhawb nqa.

Phab ntsa putty /Skim Coat hmoov thiab cov hmoov tshauv tseem ceeb calcium zoo muaj kev sib raug zoo, thiab HPMC tsis muaj kev sib raug zoo. Cov ntsiab lus calcium uas tsis tshua muaj ntawm cov calcium grey thiab qhov tsis zoo ntawm CaO thiab Ca (OH) 2 hauv cov calcium grey yuav ua rau cov hmoov poob. Yog tias muaj kev sib raug zoo me ntsis nrog HPMC, ces nws yog HPMC cov dej tsis zoo, tseem yuav ua rau cov hmoov av,Skim Coat thiab dej, ntawm phab ntsa, yog tshuaj lom neeg cov tshuaj tiv thaiv, vim yog lub cim ntawm cov khoom tshiab, phab ntsa ntawmSkim Coat nqes los ntawm phab ntsa, hauv av rau hauv hmoov, thiab tom qab ntawd siv, tsis yog kab, vim tias tau tsim cov khoom tshiab (calcium carbonate). Cov khoom tseem ceeb ntawm grey calcium hmoov yog: Ca (OH) 2, CaO thiab ib qho me me ntawm CaCO3 sib tov, CaO + H2O = Ca (OH) 2 - Ca (OH) 2 + CO2 = CaCO3↓+ H2O grey calcium nyob rau hauv dej thiab huab cua nyob rau hauv qhov kev txiav txim ntawm CO2, tsim cov calcium carbonate, thiab HPMC tsuas yog dej, auxiliary grey calcium zoo dua cov tshuaj tiv thaiv, nws tus kheej tsis koom nyob rau hauv tej yam tshwm sim.
