Sida loo soo celiyo sibidhka saldhigga caulk alkalinity? Saamaynta ku darista qaabka calcium waa mid aan caadi ahayn?

Dadka sameeya mashaariicda dhismaha waxay og yihiin in soo noqoshada ay tahay dhibaatada caadiga ah ee alaabta silicate. Sanadihii la soo dhaafay, si loo yareeyo dhacdada dhibaatadan caadiga ah, warshadaha dhismuhu waxay isticmaaleen dhoobada dhoobada sibidhka. Sida wakiilka xoogga hore ee hoobiye, qaabka kaalshiyamka ayaa si ballaaran loo isticmaalaa sababtoo ah sifooyinkeeda gaarka ah, taas oo dardargelin karta heerka adkaanta ee buuxinyaasha wadajirka ah ee sibidhka iyo hagaajinta xoogga hore ee buuxinyaasha sibidhka ku salaysan.

Maaddada caulking waxa loo qaybiyaa madoow mugdi ah oo gidaarka dibadda ah iyo walxaha gidaarka gudaha, iyo soo noqoshada caustic inta badan waxay ku dhacdaa dhismaha maalinlaha jiilaalka ama derbiga dibadda ka dib wax ka yar 24 saacadood ka dib dhismaha, nadiifinta maxalliga ah iyo roobka walxaha crystal cad. kaas oo si dhab ah u saameeya saamaynta qurxinta ee alaabta caulking.

Agabka caulking ee inta badan la isticmaalo waa: sibidh cad, budo suuf ah, wakiilka caulking, sealant iyo wixii la mid ah. Qalabkan, sibidhka cad iyo budada suufka ah ayaa ah qalab dhaqameed, laakiin labadan qalab ayaa ka maqan waxqabadka. Codsiga qaabka kaalshiyamku wuu ka sarreeyaa qalabka caagagga dhaqanka.

Guryaha iyo xulashada qaabka calcium

Calcium formate waa badeeco cad cad oo leh caanaha molecular C2H2Ca04, taas oo dedejin karta heerka fuuq-celinta sibidhka, taas oo hagaajinaysa xoogga hore ee caulk ku salaysan sibidhka, sidaas darteed ku daraya qadar ku habboonqaabka calciumsi ay u sameeyaan jiilaalka caulk sibidhka ku salaysan waa in ay dedejiyaan samaynta jel CSH, taas oo yaraynaysaa dhacdooyinka soo laabtay alkali.

Wax soo saarka miisaanka alkali ma saameyn doono oo kaliya jawiga dhismaha, dhoobada dhoobada sida saldhigga inta badan waa sababta asaasiga ah ee dhibaatada. Doorashada alaabta ku habboon ee qaabka calcium iyo qiyaasta ayaa aad muhiim u ah si loo hagaajiyo hantida anti-alkali ee alaabta wadajirka ah ee sibidhka ku salaysan. Nidaamka qaabaynta jiilaalka ee buuxinta wadajirka ah ee sibidhka ku salaysan, 1-2% ka kooban kalsiyum formate waxay si weyn u yareeyn kartaa soo noqoshada alkali ee buuxinta wadajirka ah ee sibidhka.
