Ci gaban shugabanci da kuma haƙƙin na ruwa gilashin sinadaran grouting kayan

Ana amfani da gilashin ruwa azaman mai ɗaure don kayan da ba a haɗa su ba. Hakanan ana kiranta pyrophorine. Irin waɗannan silicates na alkali ana samar da su ta hanyar narkewar yashi ma'adini tare da sodium, ko potassium, ko lithium carbonate (ko sulfate). Tsarin sinadarai na gaba ɗaya shine R2O•nSiO2•mH2O, R2O yana nufin alkali karfe oxides, kamar Na2O, K2O, Li2O; n yana nufin adadin moles na SiO2; m shine adadin moles na H2O da ya ƙunshi. Wadannan alkali karfe silicates narke a cikin ruwa da kuma hydrolyzes don samar da sol. Sol yana da kyawawan kayan siminti. Saboda haka, ana amfani da shi sosai a matsayin mai ɗaure kayan da ba a iya amfani da shi ba a cikin masana'antar, ana amfani da shi sosai azaman haɗin gwiwa a cikin masana'antar refractory, kuma ana amfani da shi azaman simintin siminti don haɓakawa a cikin gini, kuma ana amfani dashi sosai a masana'antar kera takarda da masana'anta. Jagoran haɓakawa da hasashen abubuwan da ke haifar da sinadarai na sodium silicate:

① Chemical grouting kayan da aka yafi amfani a karkashin kasa injiniya, da kuma karkashin kasa yanayi ne hadaddun da canji, wanda na bukatar ci gaban daban-daban na ruwa gilashin slurry kayan da kyau m yi bisa ga daban-daban karkashin kasa yanayi.

Ɗaya daga cikin mahimman ma'anar binciken sabon sodium silicate slurry shine cewa babban wakili na sodium silicate slurry ba zai haifar da matsalolin muhalli ba baya ga haifar da gurɓataccen alkaline, don haka lokacin zabar abubuwan da ake amfani da su, ya zama dole a yi la'akari da ko yana da guba, mai guba. kafin amfani da slurry, ko mai guba lokacin amfani, ko mai guba bayan kammala aikin. Neman abubuwan da ba su da guba sodium silicate additives shine haɓakar sabbin kayan slurry sodium silicate.

③ Ruwa gilashin ɓangaren litattafan almara abu a matsayin sinadari grouting abu yana da dogon tarihin amfani, amma ta solidification ka'idar ya zuwa yanzu, akwai har yanzu babu wani m sanarwa, don inganta wani sabon ruwa gilashin ɓangaren litattafan almara abu, shi wajibi ne don gudanar da bincike mai zurfi. akan injin gel gilashin ruwa.

(4) Tsarin polymerization da tsarin warkewa na sodium silicate slurry tsari ne mai matukar rikitarwa, kuma kawai ta hanyar fahimtar ka'idar haɓakar ciminti za mu iya ba da tushe don nazarin lokacin gelation na sodium silicate slurry.

Idan aka kwatanta da sauran sinadaran grouting kayan, babban amfani da sodium silicate slurry ne low cost, da kuma rashin amfani shi ne cewa ta ƙarfafa ƙarfin ba da kyau kamar yadda wasu sinadaran slurry, don haka da ƙarfi na sodium silicate slurry don gano m, shi ne kuma makomar kokarin kokarin.

Aikace-aikacen slurry sodium silicate a halin yanzu galibi yana iyakance ga ayyukan wucin gadi ko na dindindin, saboda bincike a cikin karko yana buƙatar zama mai zurfi.

Tsarin ci gaba na gyare-gyaren gilashin ruwa, daga mai gyara guda ɗaya zuwa haɓakar haɓakaccen haɓakawa, gwajin ya tabbatar da cewa yin amfani da gyare-gyaren gyare-gyare fiye da guda ɗaya sau da yawa yana da kyakkyawan aiki.
