Ingilazi yamanzi isetshenziswa njengesibopho sezinto ezingaphili. Eyaziwa nangokuthi i-pyrophorine. I-alkali metal silicates enjalo ikhiqizwa ukusabela kokuncibilika kwesihlabathi se-quartz nge-sodium, noma i-potassium, noma i-lithium carbonate (noma i-sulfate). Ifomula yayo yamakhemikhali evamile ithi i-R2O•nSiO2•mH2O, i-R2O ibhekisela kuma-alkali ensimbi yensimbi, njenge-Na2O, K2O, Li2O; n ibhekisela enanini lama-moles we-SiO2; m inombolo ye-moles ye-H2O equkethe. Lawa ma-silicates ensimbi ye-alkali ancibilika emanzini futhi a-hydrolyze akhe i-sol. I-sol inempahla enhle kasimende. Ngakho-ke, isetshenziswa kabanzi njengesibophezelo sezinto ezingaphili embonini, esetshenziswa kabanzi njengesibopho embonini ye-refractory, futhi isetshenziswa njenge-accelerator kasimende ekwakhiweni, futhi isetshenziswa kabanzi ekwenzeni iphepha nezimboni zendwangu. Isiqondiso sokuthuthukiswa kanye nethemba lezinto zokwakha ze-sodium silicate chemical grouting:
① Izinto zokwakha zamakhemikhali zisetshenziswa kakhulu kubunjiniyela obungaphansi komhlaba, futhi indawo engaphansi komhlaba iyinkimbinkimbi futhi iyashintsha, edinga ukuthuthukiswa kwezinhlobo ezahlukene zezinto ezidakanayo zengilazi yamanzi ngokusebenza okuhle okuphelele ngokuvumelana nezimo ezihlukahlukene ezingaphansi komhlaba.
Enye yezincazelo ezibalulekile zocwaningo lwe-sodium silicate slurry entsha ukuthi i-ejenti eyinhloko ye-sodium silicate slurry ngeke ibangele izinkinga zemvelo ngaphezu kokubangela ukungcola kwe-alkali, ngakho-ke lapho ukhetha izithasiselo, kuyadingeka ukucabangela ukuthi inobuthi, inobuthi. ngaphambi kokusetshenziswa kwe-slurry, noma ubuthi ngesikhathi sokusetshenziswa, noma ubuthi ngemuva kokuphothulwa kwephrojekthi. Ukufuna izithasiselo ze-sodium silicate ezingenabuthi kuwumkhuba wokuthuthukiswa kwezinto ezintsha ze-sodium silicate slurry.
③ I-pulp yengilazi yamanzi njengempahla yokugaya ikhemikhali inomlando omude wokusetshenziswa, kodwa isimiso sayo sokuqina kuze kube manje, asikho isitatimende esingaguquki, ukuze kuthuthukiswe into entsha ye-pulp yengilazi yamanzi, kuyadingeka ukwenza ucwaningo olunzulu. kumshini wejeli yengilazi yamanzi.
(4) I-polymerization kanye nenqubo yokuphulukisa ye-sodium silicate slurry iyinqubo eyinkimbinkimbi kakhulu, futhi kuphela ngokuqonda kuqala isimiso sokuhlanganisa usimende singanikeza isisekelo sokutadisha isikhathi se-gelation ye-sodium silicate slurry.
Uma kuqhathaniswa nezinye izinto zokwakha amakhemikhali, inzuzo enkulu ye-sodium silicate slurry yizindleko eziphansi, futhi okubi ukuthi amandla ayo okuhlanganisa awekho njengamanye ama-slurry amakhemikhali, ngakho amandla e-sodium silicate slurry ukuhlola amandla, nawo isiqondiso esizayo semizamo.
Ukusetshenziswa kwe-sodium silicate slurry okwamanje kukhawulelwe kumaphrojekthi wesikhashana noma ahlala njalo, ngoba ucwaningo lokuqina ludinga ukujula.
Inqubo yokuthuthukiswa kwezilungisi zengilazi yamanzi, kusukela kusilungisi esisodwa kuya ekuthuthukisweni kwesilungisi esiyinhlanganisela, ukuhlolwa kufakazele ukuthi ukusetshenziswa kwezilungisi eziyinhlanganisela kunesilungisi esisodwa ngokuvamile kunokusebenza okuhle kakhulu.
