Doorkee bay ka ciyaareysaa budada caagga ah ee dib loo cusboonaysiin karo ee Hoobiyaha Ku Salaysan Gypsum?

Doorkee ayay ka ciyaartaa budada caagga ah ee dib loo cusboonaysiin karo ee hoobiye ku salaysan gypsum? J: doorka budada cinjirka ee dib loo kala firdhi karo ee gypsum slurry qoyan: 1 waxqabadka dhismaha; 2 waxqabadka socodka; 3 thixotropy iyo anti-sag; 4 isbeddel isku-duubni; 5 kordhin waqtiga furan; 6 waxay kordhisaa haynta biyaha.

SaamayntaBudada dib loo celin karo ee dabacsanka dib daaweynta gypsum: 1 kordhinta xoogga jilicsanaanta (xabagta dheeraadka ah ee nidaamka gypsum); 2 xoogga foorarsiga oo sii kordhaya; 3 moodooyinka laastikada oo hoos u dhacaya; 4 sii kordheysa deformability; 5 cufnaanta walxaha sii kordhaya; 6 si loo hagaajiyo caabbinta xirashada, 7 si loo hagaajiyo isku xirnaanta, 8 si loo yareeyo nuugista biyaha walxaha, 9 si loo sameeyo maaddada hydrophobic (ku dar budada caag hydrophobic).

Waa maxay xabagta gypsum ee caadiga ah?

Jawaab: Wakiilka biyaha-haysta cellulose ether wuxuu leeyahay shaqada kordhinta adhesion ee u dhexeeya gypsum iyo saldhigga, sida baahida loo qabo in lagu xidho guddiga gypsum, gypsum block, gypsum khadadka qurxinta ee gypsum marka lagu daro wakiilka cellulose ether-xajinta, waxaad sidoo kale u baahan tahay inaad ku darto qaar ka mid ah xabagta organic, budada cinjirka ah ee la kala firdhiyo, budada caag polyvinyl alkohol, carboxymethyl cellulose (CMC) , istaarijka la beddelay, polyvinyl acetate (koollo cad) , Vinyl acetate-vinyl copolymer emulsion, iwm.

Sidee loo doortaa xabagta gypsum?

J: alkolada polyvinyl iyo karboksymethyl cellulose way ka yar yihiin biyuhu, laakiin sida gypsum waxa kaliya oo loo isticmaalaa gudaha gudaha sida koolada,Budada Latex dib loo cusboonaysiin karoShuruudaha loogu talagalay biyuhu-ilaalinta iyo adkeysiga ma sarreeyaa, markaa way ka dhaqaale badan tahay in la isticmaalo aalkolada polyvinyl iyo karboxymethyl cellulose si loo kordhiyo isku-xidhka. Polyvinyl acetate iyo vinyl acetate-vinyl copolymer emulsion waxay leeyihiin adhesion wanaagsan, caabbinta biyaha wanaagsan iyo adkeysiga, laakiin qadarka alkolada polyvinyl ayaa ka weyn kan gypsum, qiimuhuna wuu ka sarreeyaa.
