Codsiga hydroxypropyl methylcellulose ee hoobiye gypsum

Tijaabada tijaabada codsiga ee hydroxypropyl methylcellulose:
1. Tijaabada xoogga: Imtixaanka ka dib, gypsum-based hydroxypropyl methylcellulose waxay leedahay xoog isku xirnaanta oo wanaagsan iyo xoog cadaadis leh.
2. Tijaabada ka-hortagga: Ma jiro sag marka dhismaha hal baas ah lagu dhejiyo lakabyo dhumuc weyn, mana jiro sag marka la codsado in ka badan laba baas (ka sarreeya 3cm), caagaduna waa wanaagsan tahay.
3. Tijaabada gidaarada: waa fudayd oo siman marka la laadlaadsan yahay, waxaana la samayn karaa hal mar. Dusha sare waa mid jilicsan oo jilicsan, oo leh dhalaal.
4. Tijaabada heerka faafidda: Heerka faafidda ee saldhigga gypsum waxa loola jeedaa natiijada la helay iyadoo la cabbirayo cufnaanta qoyan ee saldhigga gypsum. Hal tan oo badeecada gypsum-ku-salaysan oo loogu talagalay in lagu dhiso aagga darbiga qaro weyn ee 10mm.
5. Tijaabada xadiga biyaha haynta: heerka haynta biyaha heerka GB/T28627-2012 "Plastering Gypsum", heerka haynta biyaha ee malaasta iftiinka hoose ee gypsum ayaa ka weyn ama la mid ah 60%, iyo 0.2% iyo 0.25% ee gypsum-ku salaysan hydroxypropyl methylcellulose ayaa lagu daraa Waxay leedahay waxqabad biyo celin wanaagsan.
 
Astaamahahydroxypropyl methylcellulose ee hoobiye gypsum:
1. Waxqabadka wanaagsan ee dhismaha: way fududahay oo si fudud ayaa loo laadlaadsan karaa, hal mar ayaa la qaabayn karaa, isla markaana isla markaaba balaastik leh.
2. Waafaqid xoog leh: Waxay ku habboon tahay dhammaan noocyada saldhigyada gypsum-ka, waxayna yareyn kartaa wakhtiga qulqulaya ee gypsum-ka, waxay yareyn kartaa heerka qalajinta qallajinta, darbiguna ma fududa inuu dillaaco.
3. Heerarka biyaha ee wanaagsan: waxay dheerayn kartaa wakhtiga hawlgalka saldhigga gypsum, hagaajinta caabbinta dhumucda saldhigga gypsum, kordhinta xoogga isku-xidhka u dhexeeya saldhigga gypsum iyo lakabka saldhigga, waxqabadka isku-xidhka qoyan ee wanaagsan, iyo yaraynta dambaska soo degaya iyo dhibaatooyinka kale.
4. Hagaajinta heerka fiditaanka saldhigga gypsum: Marka la barbar dhigo ether hydroxypropyl methylcellulose la mid ah, heerka faafitaanku si weyn ayaa loo kordhin doonaa. Alaabooyinka Hydroxypropyl methylcellulose waxay si weyn u kordhin karaan heerka dahaarka, waxay dabooli karaan meelo badan, waxay yareyn karaan xoogga shaqada, waxay badbaadin karaan alaabta, waxayna hagaajin karaan faa'iidooyinka dhaqaale.
5. Waxqabadka wanaagsan ee ka-hortagga: marka la laadlaado lakabyo qaro weyn, dhismo hal baas ah ma dagi doono, in ka badan laba baas, oo ka sarreeya 3cm, ma dagi doono marka la laadlaadsan yahay, caagaduna waa wanaagsan tahay.
6. Goobaha codsiga iyo qiyaasta: Malaasta gypsum ee hoose ee khafiifka ah, qiyaasta lagu taliyey waa 2.5-3.5 kg/ton.
