RDP ee xarunta is-heeraynta

Dib loo kala diri karobudada polymer RDP/VAEwaa lakab qaro weyn oo ah balastar saldhiga is-miidaaminta waxqabadka hoobiye waa wax lagu daro muhiim ah, iyada oo loo marayo tijaabadaDib loo kala diri karo budada polymer RDP/VAEon lakabka qaro weyn ee saamaynta sifooyinka jireed iyo farsamada ee gypsum saldhigga is-lejinta hoobiye, iyo iyada oo loo marayo falanqaynta microscopic ayaa shaaca ka qaaday.Dib loo kala diri karo budada polymer RDP/VAEsi loo hagaajiyo sifooyinka farsamada ee saldhigga gypsum is-heeraynta mabda'a ficil hoobiye, sharax Redispersiblebudada polymer RDP/VAEdoorka gypsum-ku-saleysan ee is-beddelka weyn.

Dib loo kala diri karobudada polymer RDP/VAEwaa binder organic si weyn loo isticmaalo kaas oo hagaajin kara sifooyinka gypsum qalabka dhismaha. Natiijooyinka tijaabada ah waxay muujinayaan in dareeraha bilowga ah ee hoobiyeyaasha is-beddelka ah ee saldhigga gypsum ee dhumucdiisuna uu kordho marka hore ka dibna hoos u dhaco korodhka qadarka isku dhafka ah ee budada koollada. Sababta ayaa ah in budada xabagta ay leedahay viscosity gaar ah oo ku jira biyaha kala diri. Marka qadarka isku dhafka ahi uu hooseeyo, kororka viscosity of slurry waxay hagaajinaysaa awoodda joojinta ee slurry si loo buuxiyo, taas oo faa'iido u leh socodka qulqulka. Marka waxa ku jira budada caaggu ay sii korodho, kororka viscosity-ku wuxuu keenaa kororka viscosity slurry iyo hoos u dhaca dheecaanka. Qadarka budada koollada ayaa saameyn yar ku leh dareeraha 20min ee hoobiye.

Dib loo kala diri karobudada polymer RDP/VAEsida nooc ka mid ah binder organic, xoojinta horumarinta waxay ku xiran tahay uumiga biyaha slurry, xoogga bond, filim samaynta foornada xaaladaha qalalan qoyaanka, gypsum ku salaysan is-ledgering budada hoobiye samayn karaa filim joogto ah, leeyihiin bond wanaagsan iyo foornada xoog qalalan Hoobiye is-heereeya oo gypsum ku salaysan oo leh budada ayaa kordhaysa.

Iyagoon ku darinDib loo kala diri karo budada polymer RDP/VAEHayso wax badan oo gypsum ah oo ku salaysan hoobiye is-heereeya, kiristaalo dihydrate gypsum kiristaalo ah iyo baakad aan caadi ahayn Inta u dhaxaysa kiristaalo gypsum dihydrate iyo kiristaalo gypsum dihydrate iyo crisscross isku darka u dhexeeya baakadaha, iyada oo si aan joogto ahayn si adag loo soo ururiyey ka dhigi gypsum ku salaysan taar is-heer, lagu daray xoog is-heer.Dib loo kala diri karo budada polymer RDP/VAEgypsum-ku-saleysan hoobiye is-heejeynaya,Dib loo kala diri karo budada polymer RDP/VAEon formation of gypsum ku salaysan isku-xirnaanta hoobiye filamentous is-heer, kiristaalo gypsum dihydrate iyo baakad, buundada organic sameeyay inta u dhaxaysa kiristaalo iyo crystal, film organic waxaa la sameeyay on kiristaalo gypsum fuuq-bax, qaybaha is dul saaran ee u dhexeeya baakadaha kiristaalo gypsum dihydrate iyo xidhiidhka, si ay u Kordhi isku-xidhka gypsum-ku-salaysan hoobiyeyaasha is-heereeya iyo xoogga isku-xidhan, Hagaajinta xoogga gypsum ku salaysan hoobiye is-lejoDib loo kala diri karo budada polymer RDP/VAEHoobiye leh membranous, waxay wanaajin kartaa isku-duubnida hoobiyeyaasha qalalan iyo xoogga curaarta, budada u dhaxaysa kiristaalo gypsum dihydrate iyo filim xidhidhiyaha samaynta arrin ka mid ah kiristaalo gypsum dihydrate iyo xidhid wax ku ool ah ayaa la sameeyaa inta u dhaxaysa buuxinta iyo hagaajinta isku xidhka u dhexeeya kiristaalo gypsum-biyoodka iyo baakad , Sidaa darteed, xoogga dammaanadda ee saldhigga gypsum-ka hoobiyeyaasha is-beddelka ah ayaa la wanaajiyey si makroscopically ah.
