Lub luag haujlwm tseem ceeb ntawm cov dej-solubleHydroxypropyl methyl cellulose HPMCnyob rau hauv mortar yog ib qho tseem ceeb nyob rau hauv peb yam, ib tug zoo heev dej tuav kev muaj peev xwm, ob yog kev puas tsuaj rau lub viscosity thiab compressibility ntawm mortar, peb yog kev sib cuam tshuam nrog cov cement.Cov dej tsis zoo khaws cia ntawm mortar nyob rau hauv tag nrho cov txheej txheem ntawm kev thauj mus los yog ib qho yooj yim rau cais cov dej tawm, kis rau ntawm qhov chaw ntawm cov khoom ntxeem tau, feem ntau ntawm cov dej yog ib qho yooj yim absorbed rau zom, tsim kev hloov feature ntawm lub mortar, mortar down qhov kev puas tsuaj ntawm mortar. tag nrho cov coagulation ib txwm muaj thiab cov khoom me me ntawm cov khoom siv raw hauv nruab nrab ntawm kev sib txuas thiab yog li txo cov compressive zog ntawm masonry phab ntsa.Cov dej tuav ntawm mortar yog piav qhia los ntawm stratification.
Qhov ntau dua qhov viscosity ntawmhydroxypropyl methyl celluloseHPMC, qhov zoo dua cov dej tuav kev ua tau zoo, qhov zoo dua qhov viscosity ntawm polymer aqueous tov.Qhov ntev thiab cov duab ntawm cov saw molecular kuj nyob ntawm qhov txheeb ze molecular loj ntawm cov polymer (iav hloov kub).Tus naj npawb ntawm cov pab pawg ua haujlwm tseem cuam tshuam rau qhov viscosity ntau.
Hydroxypropyl methyl cellulose HPMC tus kheej cov dej tuav kev ua tau zoo los ntawm hydroxypropyl methyl cellulose nws tus kheej solubility thiab rau dej siv.Nws paub zoo tias cellulose yog insoluble hauv dej vim nws cov qauv crystalline siab, txawm hais tias cov saw hlau molecular ntawm fiber ntau muaj ntau ntau OH pawg.
Lub zog covalent bonds thiab van der Waals rog ntawm cov qauv molecular tsis tuaj yeem them rau los ntawm kev muaj peev xwm hydration ntawm pawg methyl ib leeg.Yog li ntawd, nws tuaj yeem yaj hauv dej xwb.Thaum hloov cov molecules tau qhia, tsis tsuas yog cov molecules hloov pauv puas tsuaj rau cov saw hlau hydrogen, tab sis kuj covalent bonds hauv cov saw hlau hydrogen raug rhuav tshem los ntawm kev hloov pauv molecules wedges nyob ze cov saw hlau.Qhov ntau dua qhov hloov pauv, qhov sib txawv ntawm molecular ntau dua.Qhov ntau dua qhov kev siv ntawm kev rhuav tshem covalent bonds.Thaum cov fiber ntau lattice nthuav dav, cov tshuaj aqueous nkag mus thiab hydroxypropyl methyl cellulose ua dej-soluble, ua rau cov kua dej khov heev.
Raws li ambient kub nce, lub polymer lub hydration yuav tsis zoo thiab dej yog tsav los ntawm nruab nrab ntawm cov saw hlau.Thaum cov dej txaus raug tshem tawm, cov qauv molecular maj mam sib sau ua ke, ua kom muaj peb-dimensional network ntawm cov ntaub so ntswg uas tuaj yeem ncav cuag.Qhov viscosity, ntau npaum li cas, qhov loj me thiab daim ntawv thov kub ntawm hydroxypropyl methyl cellulose yog cov yam ntxwv uas ua rau muaj kev phom sij rau cov dej khaws cia ntawm mortar.
Hydroxypropyl methyl cellulose viscosity muab faib ua: viscosity 100,000, viscosity 150,000, viscosity 200,000.
Yuav ua li cas xaiv hydroxypropyl methyl cellulose?
100,000 viscosity hydroxypropyl methyl cellulose tuaj yeem siv los ua tha xim sab hauv phab ntsa putty hmoov.Pobzeb binder.Tus neeg sawv cev Caulking.Bonded qhob mortar.High toughness tsis shrinkage grouting khoom.
Inorganic rwb thaiv tsev rwb thaiv tsev mortar specification yog siab dua, viscosity ntawm 150 txhiab hydroxypropyl methyl cellulose los yog 200 txhiab hydroxypropyl methyl cellulose.Yog tias xaiv cov txiv hmab txiv ntoo tshiab uas viscosity yog 100 txhiab, tsim cov dej ntws los dai qhov tshwm sim yooj yim heev.
Lub luag haujlwm tseem ceeb ntawm methyl cellulose yog dej tuav, ua raws li thickening.Yuav tsum dhuav nrog me nyuam hmoov nyob rau hauv sab hauv phab ntsa, yog hais tias nws muaj zoo dej yaj thiab inferior viscosity (70000-80000), tseem tuaj yeem thov.Thaum lub viscosity siab tshaj 100,000, lub viscosity tsis muaj teeb meem rau dej tuav.Hauv kev tsim thiab tsim cov khoom siv sab hauv phab ntsa putty hmoov, tsis tas yuav xaiv 200,000 viscosity.Vim tias cov viscosity loj dhau, nws nyuaj rau khawb thiab khawb hauv qhov ntau.
Hydroxypropyl methyl cellulose siv viscosity ntawm 100,000.
