Cov iav ua kua, cov kua nplaum ua haujlwm - cov ntaub ntawv paub zoo rau peb, vim lawv tau siv dav hauv lub neej txhua hnub. Tab sis, tej zaum, peb cov ntaub ntawv hais txog lawv muaj tsawg heev, tab sis tib lub sij hawm, kawm txog soluble poov tshuaj silicate, uas ua hauj lwm raws li lub hauv paus rau lawv siv, tsis yog tsuas yog nthuav, tab sis kuj pab tau. Ntawm no yog vim li cas.

Tsawg tus neeg tau hnov tias cov poov tshuaj silicates cuam tshuam nrog xws li "cov tshuaj tua kab mob txaus ntshai". Qhov tseeb, yuav ua li cas cov neeg uas tsis cuam tshuam nrog kev tsim tshuaj lom neeg paub tias lawv yog E560 cov khoom noj ntxiv uas tiv thaiv clumping thiab caking. Lawv yog siv nyob rau hauv ci, zus tau tej cov granulated qab zib, hmoov mis thiab lwm yam hmoov khoom noj khoom haus, raws li zoo raws li nyob rau hauv cov tshuaj thiab tshuaj pleev ib ce nyob rau hauv kev tsim cov hmoov thiab gels. Nws tsis tuaj yeem hais meej meej tias cov poov tshuaj silicate (formula Na2O (SiO2) n) yog ib qho kev phom sij txaus ntshai, txij li kev tso cai noj txhua hnub tsis tau txiav txim siab. Nyob rau hauv Lavxias teb sab Federation, cov additive yog tso cai, txawm lub fact tias nws tseem tsis tau dhau qhov tsim nyog kev xeem thiab kev xeem. Qhov no yuav tsum paub thiabcoj mus rau hauv tus account hauv lub neej txhua hnub.

Thiab tam sim no cia peb tham txog cov iav kua, uas yog cov khoom paub zoo tshaj plaws raws li cov poov tshuaj silicate. Kev tsim tshuab yog qhov nyuaj, yog li kev tsim cov silicate blocks yog qhov muaj txiaj ntsig zoo ntawm cov nroj tsuag tshuaj. Nyob rau hauv luv luv, lub essence ntawm cov txheej txheem yog hais tias ua ke ntawm nplua quartz xuab zeb nrog dej qab zib yog raug rho tawm haujlwm nyob rau hauv ib lub qhov cub ntawm qhov kub thiab txias, ces cov poov tshuaj silicate tau nyob rau hauv daim ntawv ntawm ib tug pob yog crushed, thiab tsuas yog tom qab ntawd muaj peev xwm ib tug aqueous tov. tau los ntawm nws. Raws li qhov tseeb tias potash, uas muaj tus nqi siab, kuj tseem siv los ua cov khoom siv raw hauv kev tsim cov poov tshuaj silicate lumps, poov tshuaj silicate, tsis zoo li sodium silicate, tsis pom daim ntawv thov loj. Nyob rau hauv 90%, sodium silicate los yog nws cov sib tov nrog poov tshuaj silicate yog siv kom tau cov iav kua.

Cov kua muaj pes tsawg leeg raws li cov poov tshuaj silicate yog qhov tsis txaus ntseeg rau cov kua qaub thiab muaj kev tiv thaiv siab rau huab cua. Qhov chaw kho nrog cov iav poov tshuaj tsis ua rau lub ntsej muag tsis pom kev, yog li nws feem ntau siv los tsim ntau hom xim, thiab ob peb xyoos dhau los, cov iav ua kua tau pib siv los ua cov polishing tsheb. Hauv kev tsim kho, potash iav yog siv los ua impregnations thiab additives - ntxiv rau cov cement mortars, putties thiab plasters tuaj yeem ua rau lawv lub zog thiab cov yam ntxwv ntawm rwb thaiv tsev.

nplaim taws retardant xim uas muaj poov tshuaj silicate yog txheej zoo heev rau pej xeem phab ntsathaj chaw. Kev kho deg nrog cov khoom sib xyaw nrog qhov sib ntxiv ntawm cov iav ua kua ua rau lawv tiv thaiv corrosion thiab waterproofing zog, tiv taus kub kub. Hauv kev lag luam tshuaj, cov tshuaj no koom nrog hauv kev tsim cov sodium metasilicate, silica gel khoom adsorbent thiab lead silicate. Hauv ferrous metallurgy, nws yog siv rau kev tsim cov pwm, nyob rau hauv foundry - raws li tus neeg sawv cev flotation. Nco qab tias cov ntaub nplaum uas paub zoo kuj tseem muaj cov poov tshuaj / sodium silicate thiab siv los ua cov iav, ntoo, hlau thiab ntawv.

Reminder: Cov iav kua, txawm tias tsis muaj tshuaj lom, tseem yuav tsum tau ua tib zoo tuav. Yog tias cov khoom nkag mus rau ntawm daim tawv nqaij lossis qhov muag, yaug tam sim nrog dej sov kom txaus.
