Lagu daro la taaban karo oo khafiif ah | Wakiilada Xumbaynta Waxqabadka Sare ee Shabka Gacanta
Waxyaabaha lagu daro kiimikaad adag waxay kordhiyaan xoogga iyo caabbinta naaxinta ee sagxadaha shubka ah waxayna sidoo kale caawiyaan ilaalinta dusha sare ee soo galinta qoyaanka.. Qallajiyeyaasha sagxada la taaban karo ayaa ku habboon in loo isticmaalo bakhaarrada iyo xarumaha kale ee warshadaha halkaasoo boodhka laga ilaaliyo, adkaaday, Kiimikada iyo sagxadaha u adkaysta nabarka ayaa la rabaa. additive la taaban karos sidoo kale wax ku ool ah marka lagu isticmaalo qalabka sinta shubka shahaado cagaaran iyo shiidi dheeman si loo abuuro mid aad u milicsan, sheen la taaban karo sare dhameysatay.
Guud ahaan hadalka, kiimikaad qallafsan/ adkeeye ayaa ka kooban silicates, cusbada milmay ama silikoonada ee ka falcesha kalsiyum hydroxide daciifka ah ee shubka marka uu qoyan yahay oo la marsado dusha shubka mar marka ay horeba u bogsatay si ay u adkeyso isu geynta. Inta badan qallajiyeyaasha dareeraha ah waxay si qoto dheer u galaan shubka iyo ilaa inta qoyaanku jiro waxay sii wadi doonaan inay si kiimiko ah uga falceliyaan calcium hydroxide daciif ah si ay u soo saaraan mid adag., dusha cufan.
Sababta asaasiga ah ee loo sugo 7 maalmo ka hor inta aan la isticmaalin qallajiye kiimiko ah waa tan shubka guud ahaan lagu gaaro 60-65% ee fuuq-celinta muddadan gudaheeda, taasoo keentay in shubka uu soo saaro calcium hydroxide xad-dhaaf ah. Adigoo sugaya, waxaa jira goobo badan oo loo heli karo fal-celinta kiimikaad taasina waxay awood u siinaysaa adkaanta iyo cufnaanta inay si degdeg ah u dhacaan.
Khuraafaad caadi ah ayaa ah in kiimikaad qallafsan uu ka dhigo qaab-dhismeedka crystalline tobermorite ee koollada sibidhka ee fuuqbaxay, si kastaba ha ahaatee khubarada warshadaha ayaa isku raacay in tani aysan ahayn xaaladdu. Kiimikada qallafsan, marka si sax ah oo joogto ah loo codsado, yaree porosity ee shubka adigoo buuxinaya xididada ku jira shubka silicates, sidaas darteed hoos u dhigista xaddiga uumiga biyaha ee awood u leh inuu dhex maro shubka, iyadoo la kordhinayo nabarrada iyo xirashada caabbinta.
