Anhydrous Sodium Sulphate thiab Decahydrate Sodium Sulphate: Core Application Difference

Sodium sulphate muaj nyob rau hauv ob hom hydrate: anhydrous sodium sulphate (Na₂SO₄) thiab decahydrate sodium sulphate (Na₂SO₄·10H₂O), tseem hu ua Glauber's ntsev. Thaum ob daim ntawv qhia tib yam tshuaj mis (thaum anhydrous), lawv lub cev muaj zog, ruaj khov, thiab kev siv sib txawv. Rau cov neeg siv khoom lag luam thiab cov neeg xa khoom, kev nkag siab txog qhov sib txawv ntawm daim ntawv thov no yog qhov tseem ceeb rau kev xaiv cov qauv ntawm sodium sulphate rau cov kev xav tau tshwj xeeb, kom ntseeg tau tias kev ua tau zoo thiab tus nqi -effectiveness.

 

Anhydrous sodium sulphate yog qhuav, dawb crystalline hmoov tsis muaj dej ntawm crystallization. Nws muaj cov ntsiab lus melting siab (884 degree), cov ntsiab lus tsis muaj dej noo (tsawg dua lossis sib npaug li 0.2%), thiab kev ruaj ntseg zoo, ua rau nws tsim nyog rau cov ntaub ntawv qhuav, ruaj khov raw khoom. Nws yog soluble hauv dej, nrog rau solubility ntawm 28.1 g / 100 ml ntawm 25 degree, thiab tsis clump yooj yim, kom ntseeg tau zoo flowability thiab dispersion nyob rau hauv formulations.

 

Cov kev siv tseem ceeb ntawm anhydrous sodium sulphate yog nyob rau hauv cov tshuaj ntxuav tes, dyeing, thiab kev tsim kho kev lag luam. Nyob rau hauv cov tshuaj detergents, nws yog siv los ua ib tug muab tub lim thiab builder, muab zoo heev flowability thiab tiv thaiv caking. Nyob rau hauv dyeing, nws ua raws li tus neeg sawv cev theem, kom ntseeg tau cov xim ntawm cov ntaub. Hauv kev tsim kho, nws yog siv los ua cov txheej txheem nrawm rau cov cement thiab pob zeb, qhov twg nws daim ntawv qhuav ua kom zoo ib yam thiab tsis txhob ya raws - cov teeb meem cuam tshuam. Anhydrous sodium sulphate kuj tseem siv rau hauv daim ntawv ua thiab iav kev lag luam, qhov twg nws cov stability thiab solubility tseem ceeb heev.

 

Decahydrate sodium sulphate yog crystalline khoom uas muaj kaum molecules dej ntawm crystallization. Nws muaj qhov qis dua melting point (32.38 degree) thiab cov dej noo ntau dua, thiab nws nyiam poob dej thaum raug huab cua, tsim cov sodium sulfate anhydrous. Qhov xwm txheej hygroscopic no ua rau nws tsis haum rau cov ntawv thov uas xav tau cov ntaub ntawv qhuav, tab sis nws muaj cov khoom tshwj xeeb uas ua rau nws zoo tagnrho rau kev siv tshwj xeeb.

 

Decahydrate sodium sulphate feem ntau yog siv nyob rau hauv kev lag luam kws tshuaj raws li ib tug laxative, qhov twg nws muaj peev xwm nqus dej nyob rau hauv txoj hnyuv pab txhawb plab hnyuv. Nws kuj tseem siv rau hauv kev lag luam tshuaj raws li cov khoom siv raw rau kev tsim lwm cov tshuaj sodium, xws li sodium sulfide thiab sodium silicate. Tsis tas li ntawd, nws yog siv rau hauv kev siv cua txias, xws li cov pob khoom txias, qhov twg nws qhov kev sib cais ntawm cov dej ua kom txias.

 

Qhov sib txawv tseem ceeb ntawm anhydrous thiab decahydrate sodium sulphate yog nyob rau hauv lawv cov dej noo, ruaj khov, thiab kev siv. Anhydrous sodium sulphate yog qhov zoo tagnrho rau cov ntawv thov kev lag luam uas xav tau cov ntaub ntawv qhuav, ruaj khov, thaum decahydrate sodium sulphate yog qhov nyiam rau kev siv tshuaj thiab cua txias. Rau cov neeg xa khoom, muab ob daim ntawv tso cai rau lawv ua kom haum rau ntau yam ntawm cov neeg yuav khoom xav tau, los ntawm cov tuam txhab lag luam mus rau cov tuam txhab tshuaj.

 

Los ntawm kev nkag siab txog qhov tseem ceeb ntawm daim ntawv thov sib txawv ntawm ob daim ntawv no, cov neeg yuav khoom tuaj yeem xaiv qhov zoo tshaj plawssodium sulfaterau lawv cov txheej txheem tsim khoom tshwj xeeb, ua kom zoo thiab tus nqi -kev ua tau zoo. Rau cov neeg xa khoom, qhia txog qhov sib txawv no pab cov neeg yuav khoom txiav txim siab paub thiab ntxiv dag zog rau lawv txoj haujlwm hauv kev lag luam thoob ntiaj teb.
