Muraayadaha biyaha waxaa loo isticmaalaa sida xiraha alaabta aan organic ahayn. Sidoo kale loo yaqaan pyrophorine. Silicates biraha alkali ee noocan oo kale ah waxaa soo saara falcelinta dhalaalka ee ciid quartz leh sodium, ama potassium, ama lithium carbonate (ama sulfate). Qaaciidada kiimikada guud waa R2O•nSiO2•mH2O, R2O waxaa loola jeedaa oksaydhyada birta alkali, sida Na2O, K2O, Li2O; n waxaa loola jeedaa tirada moles ee SiO2; m waa tirada moles ee H2O ay ka kooban tahay. Silicates-yadan alkali-ku waxay ku milmaan biyaha waxayna ku milmaan biyo si ay u sameeyaan sol. Sol waxay leedahay hanti sibidhyo oo wanaagsan. Sidaa darteed, waxaa si ballaaran loo isticmaalaa sida xiraha walxaha inorganic ee warshadaha, oo si ballaaran loo isticmaalo sida bond in warshadaha refractory, iyo waxaa loo isticmaalaa sida dardargelinta shubka sibidhka ee dhismaha, iyo sidoo kale aad loo isticmaalo in waraaqaha iyo warshadaha dharka. Jihada horumarinta iyo rajada laga qabo soodhiyam silicate walxaha grouting kiimikaad:
① Qalabka grouting kiimikaad waxaa inta badan loo isticmaalaa in injineernimada dhulka hoostiisa, iyo deegaanka dhulka hoostiisa waa adag yahay oo la beddeli karo, taas oo u baahan horumarinta noocyada kala duwan ee alaabta slurry galaas biyaha leh waxqabad dhamaystiran oo wanaagsan sida ay deegaanka kala duwan ee dhulka hoostiisa.
Mid ka mid ah macnaha muhiimka ah ee daraasadda cusub ee sodium silicate slurry waa in wakiilka ugu muhiimsan ee sodium silicate slurry uusan keeni doonin dhibaatooyinka deegaanka marka lagu daro inuu keeno wasakhowga alkaline, marka marka la dooranayo waxyaabaha lagu daro, waxaa lagama maarmaan ah in la tixgeliyo haddii ay tahay sun, sun ah. ka hor inta aan la isticmaalin slurry, ama sun inta lagu jiro isticmaalka, ama sun ka dib dhamaystirka mashruuca. Raadinta waxyaabaha lagu daro sodium silicate-ka ee aan sunta ahayn waa isbeddelka horumarka ee walxaha cusub ee soodhiyam silicate.
③ Maaddada saxarka galaaska biyaha sida walxaha grouting kiimikaad waxay leedahay taariikh dheer oo la isticmaalo, laakiin mabda'eeda adkeynta ilaa hadda, wali ma jiro hadal joogto ah, si loo horumariyo wax cusub oo saxarka galaaska, waxaa lagama maarmaan ah in la sameeyo cilmi-baaris qoto-dheer. habka gel galaaska biyaha.
(4) Nidaamka polymerization iyo daawaynta ee soodhiyam silicate slurry waa hab aad u adag, oo kaliya marka ugu horeysa ee la fahmo mabda'a xoojinta sibidhka waxaan ku siin karnaa saldhig lagu baranayo wakhtiga gelation ee sodium silicate slurry.
Marka la barbar dhigo qalabka kale ee kiimikaad grouting, faa'iidada ugu weyn ee soodhiyam silicate slurry waa qiimo jaban, iyo khasaaraha waa in ay xoog xoojinta ma aha sida wanaagsan sida qaar ka mid ah slurry kiimikaad, si xoogga sodium silicate slurry si ay u sahamiyaan ka iman kara, sidoo kale waa a jihada mustaqbalka dadaalka.
Codsiga slurry sodium silicate wuxuu hadda inta badan ku xaddidan yahay mashruucyo ku meel gaar ah ama badh-joog ah, sababtoo ah cilmi-baarista adkeysiga waxay u baahan tahay inay noqoto mid qoto dheer.
Habka horumarinta ee wax-ka-beddelayaasha muraayadaha biyaha, laga bilaabo hal-beddele ilaa horumarinta wax-ka-beddelka isku-dhafka ah, tijaabadu waxay caddeeyeen in isticmaalka wax-beddelayaasha isku-dhafka ah marka loo eego hal-beddeleyaashu inta badan waxay leeyihiin waxqabad aad u fiican.
