Development ntụziaka na atụmanya nke mmiri iko chemical grouting ihe

A na-eji iko mmiri eme ihe dị ka ihe nkedo maka ihe ndị na-emepụta ihe.A makwaara dị ka pyrophorine.A na-emepụta silicates alkali dị otú ahụ site na mmeghachi omume na-agbaze nke ájá quartz na sodium, ma ọ bụ potassium, ma ọ bụ lithium carbonate (ma ọ bụ sulfate).Usoro kemịkalụ ya n'ozuzu bụ R2O•nSiO2•mH2O, R2O na-ezo aka na alkali metal oxides, dị ka Na2O, K2O, Li2O;n na-ezo aka na ọnụ ọgụgụ nke mole nke SiO2;m bụ ọnụọgụ mole nke H2O nwere.Ndị a alkali metal silicates igbari na mmiri na hydrolyzes na-etolite sol.Sol nwere ezigbo cimentation.Ya mere, a na-eji ya eme ihe dị ka ihe eji eme ihe na-emepụta ihe na-emepụta ihe na ụlọ ọrụ, nke a na-ejikarị eme ihe dị ka njikọ na ụlọ ọrụ refractory, a na-ejikwa ya dị ka ihe na-eme ngwa ngwa simenti na-ewu ụlọ, a na-ejikwa ya na-emepụta akwụkwọ na ụlọ ọrụ akwa.Ntuziaka mmepe na atụmanya nke ihe ndị na-eme ka mmiri ọgwụ sodium silicate:

① Chemical grouting ihe na-tumadi ji n'okpuruala engineering, na n'okpuruala gburugburu ebe obibi bụ mgbagwoju na mgbanwe, nke na-achọ mmepe nke dị iche iche iche iche nke mmiri iko slurry ihe na ezi keukwu arụmọrụ dị ka dị iche iche n'okpuruala gburugburu.

Otu n'ime ihe dị mkpa pụtara ọmụmụ nke ọhụrụ sodium silicate slurry bụ na onye isi nke sodium silicate slurry agaghị eme ka nsogbu gburugburu ebe obibi na mgbakwunye na-akpata mmetọ alkaline, yabụ mgbe ị na-ahọrọ ihe mgbakwunye, ọ dị mkpa ịtụle ma ọ bụ ihe na-egbu egbu, na-egbu egbu. tupu eji slurry, ma ọ bụ na-egbu egbu n'oge eji, ma ọ bụ na-egbu egbu mgbe emechara ọrụ ahụ.Ịchọ ihe mgbakwunye sodium silicate na-adịghị egbu egbu bụ usoro mmepe nke ihe ọhụrụ sodium silicate slurry.

③ Mmiri iko pulp ihe dị ka a chemical grouting ihe nwere ogologo akụkọ ihe mere eme nke ojiji, ma ya solidification ụkpụrụ dị ugbu a, e nwere ka ọ dịghị agbanwe agbanwe nkwupụta, ịzụlite ọhụrụ mmiri iko pulp ihe, ọ dị mkpa iji mepụta na-omimi nnyocha. na mmiri iko gel usoro.

(4) Usoro polymerization na ọgwụgwọ nke sodium silicate slurry bụ usoro dị mgbagwoju anya, na naanị site n'ịghọta ụkpụrụ nke ciment consolidation anyị nwere ike inye ihe ndabere maka ịmụ oge gelation nke sodium silicate slurry.

Tụnyere ndị ọzọ chemical grouting ihe, nnukwu uru nke sodium silicate slurry bụ ala na-eri, na mwepu bụ na ya consolidation ike adịghị mma dị ka ụfọdụ chemical slurry, otú ike nke sodium silicate slurry inyocha nwere ike, bụkwa a. ọdịnihu ntụziaka mgbalị.

Ngwa nke sodium silicate slurry bụ ugbu a na-ejedebe na ọrụ nwa oge ma ọ bụ nke na-adịgide adịgide, n'ihi na nyocha na ịdịte aka kwesịrị ịdị omimi.

Usoro mmepe nke ndị na-eme ihe na-eme ka iko mmiri, site na otu onye na-emegharị ihe na-emepụta ihe na-emepụta ihe na-emepụta ihe, nchọpụta ahụ gosipụtara na iji ihe ndị na-emepụta ihe na-eme ka ihe na-eme ka ọ bụrụ otu ihe na-arụ ọrụ na-enwekarị arụmọrụ dị mma.
