Girasi remvura rinoshandiswa sebhainda kune inorganic zvinhu.Iyo inozivikanwawo se pyrophorine.Alkali metal silicates yakadaro inogadzirwa nekunyunguduka kwejecha requartz rine sodium, kana potassium, kana lithium carbonate (kana sulfate).Yayo yekemikari formula ndeye R2O•nSiO2•mH2O, R2O inoreva alkali metal oxides, seNa2O, K2O, Li2O;n inoreva nhamba yema moles eSiO2;m ndiyo nhamba yemamoles eH2O iyo ine.Aya alkali simbi silicates inonyungudika mumvura uye hydrolyze kuita sol.Iyo sol ine yakanaka simende pfuma.Naizvozvo, inoshandiswa zvakanyanya senge inorganic material binder muindastiri, inoshandiswa zvakanyanya sechisungo muindasitiri inodzoreredza, uye inoshandiswa sesimende kongiri yekumhanyisa mukuvaka, uye zvakare inoshandiswa zvakanyanya mukugadzira mapepa uye maindasitiri emachira.Kuvandudza kutungamira uye tarisiro yesodium silicate kemikari grouting zvinhu:
① Chemical grouting zvinhu zvinonyanya kushandiswa muuinjiniya hwepasi, uye nharaunda yepasi pevhu yakaoma uye inoshanduka, inoda kuvandudzwa kwemhando dzakasiyana dzemvura yegirazi slurry zvinhu zvine kuita kwakanaka kwakazara zvinoenderana nenzvimbo dzakasiyana dzepasi.
Imwe yezvakakosha zvinoreva chidzidzo chesodium silicate slurry nyowani ndechekuti iyo main agent yesodium silicate slurry haizokonzerese matambudziko ezvakatipoteredza kunze kwekukonzera kusvibiswa kwealkaline, saka pakusarudza zvinowedzera, zvakakosha kufunga kuti ine chepfu, ine chepfu. isati yashandiswa slurry, kana chepfu panguva yekushandiswa, kana chepfu mushure mekupedzwa kweprojekti.Kutsvaga isiri-chepfu sodium silicate additives ndiyo yekusimudzira maitiro ezvitsva zvesodium silicate slurry zvinhu.
③ Mvura yegirazi pulp zvinhu semakemikari grouting zvinhu zvine nhoroondo refu yekushandiswa, asi iyo yekusimbisa musimboti kusvika pari zvino, hapasati pasisina chirevo chinopindirana, kugadzira girazi remvura nyowani pulp zvinhu, zvakakosha kuita tsvakiridzo yakadzama. pamvura girazi gel mechanism.
(4) Iyo polymerization uye kurapa maitiro e sodium silicate slurry inzira yakaoma kwazvo, uye chete nekutanga kunzwisisa musimboti wekusimbisa simende tinogona kupa hwaro hwekudzidza iyo gelation nguva ye sodium silicate slurry.
Kuenzaniswa nemamwe makemikari grouting zvinhu, iyo yakakura mukana wesodium silicate slurry inodhura yakaderera, uye chakashata ndechekuti kusimba kwayo kwekubatanidza hakuna kunaka seimwe kemikari slurry, saka kusimba kwesodium silicate slurry yekuongorora zvinogona, zvakare kutungamira kwemangwana kwekuedza.
Iko kushandiswa kwesodium silicate slurry parizvino kunonyanya kugumira kumapurojekiti enguva pfupi kana semi-chisingaperi, nekuti tsvakiridzo mukusimba inoda kuve yakadzama.
Maitiro ekuvandudza emvura egirazi modhifita, kubva kune imwe chete modifier kuenda kune composite modifier kuvandudza, kuyedza kwakaratidza kuti kushandiswa kweanosanganisa ekugadzirisa pane imwe modhifita inowanzova nekuita kwakanakisa.
