Cov Ntsiab Lus Tseem Ceeb ntawm Sodium Sulfate rau Kev Siv Xab Npum: Lawv Txhais Li Cas Hauv Cov Lus Siv Tau
Hauv kev lag luam ntxuav khaub ncaws, sodium sulfate ua haujlwm ua cov khoom siv raw tseem ceeb. Txawm hais tias ua haujlwm ua tus neeg muab khoom thiab tus neeg sawv cev sib npaug, nws cov txheej txheem kev teeb tsa ua lub luag haujlwm tseem ceeb hauv kev ua haujlwm zoo ntawm kev tsim khoom, kev sib xws ntawm cov mis, thiab cov tsos ntawm cov khoom. Kev nkag siab txog cov txheej txheem no ua rau muaj kev txiav txim siab ntau dua raws li cov txheej txheem xav tau.
Nov yog cov kev ntsuas uas feem ntau siv thiab lawv cov txiaj ntsig siv tau:
1. Kev dawb
-
Kev Txhais & Qhov Tseem Ceeb: Qhia txog qhov ci ntsa iab ntawm sodium sulfate, feem ntau cuam tshuam rau qhov tsos kawg ntawm cov hmoov ntxuav khaub ncaws.
-
Feem ntau ntawm cov khoom siv: 80% -92% rau qib ntxuav xab npum.
-
Lus Cim: Hauv cov mis uas xav tau qhov dawb ntawm cov khoom, cov khoom siv dawb dua yuav raug xaiv dua.
2. Kev Faib Tawm Qhov Loj ntawm Cov Khoom Me Me
-
Kev Txhais & Qhov Tseem Ceeb: Cuam tshuam rau kev ntws ntawm cov khoom siv, kev sib xyaw ua ke, thiab yooj yim ntawm kev tuav thaum lub sijhawm ntim khoom.
-
Ntau Yam Sib Xws: 40–80 mesh.
-
Lus Cim: Kev sib phim qhov loj ntawm cov khoom me me rau cov cuab yeej siv pab ua kom muaj kev ntws zoo.
3. Cov dej tsis yaj
-
Kev Txhais & Qhov Tseem Ceeb: Cov tshuaj uas tsis yaj thiab tsis yaj hauv dej. Tseem ceeb rau cov ntawv thov uas muaj kev ziab tshuaj tsuag lossis cov kav dej uas rhiab heev.
-
Qib Txheem: Feem ntau ≤0.05%, nrog rau cov ntawv thov nruj dua uas xav tau ≤0.02%.
-
Lus Cim: Kev xaiv cov khoom lag luam uas ua tiav zoo yuav pab txo qhov kev pheej hmoo ntawm kev txhaws lossis kev cuam tshuam kev saib xyuas.
4. Cov ntsiab lus noo noo
-
Kev Txhais & Qhov Tseem Ceeb: Txheeb xyuas qhov qhuav ntawm cov khoom, cuam tshuam rau nws txoj kev nyiam ua ncuav thaum lub sijhawm khaws cia lossis thauj mus los.
-
Tus nqi ib txwm muaj: ≤0.20%
-
Lus Cim: Rau cov chaw noo noo, tej zaum yuav zoo dua yog siv cov ntim khoom uas tsis muaj dej noo ntau los yog cov uas tiv thaiv dej noo.
5. Cov ntsiab lus ntawm Sodium Sulfate (Na₂SO₄)
-
Kev Txhais & Qhov Tseem Ceeb: Qhia txog qib purity ntawm cov khoom.
-
Cov Nqi Siv Los Xam: ≥98% yog ib txwm muaj rau qib tshuaj ntxuav tes; ≥99% yuav raug teev tseg rau qee qhov kev siv.
-
Lus Cim: Cov ntsiab lus siab dua pab txhawb rau qhov sib txawv tsawg dua hauv cov qauv.
6. pH (1% Cov Tshuaj Aqueous)
-
Kev Txhais & Qhov Tseem Ceeb: Lub pH ntawm 1% cov tshuaj qhia txog qhov xwm txheej acid-base ntawm cov khoom siv hauv cov dej-raws li.
-
Pom Zoo Ntau Yam: 6.5–8.5
-
Lus Cim: pH nruab nrab mus rau me ntsis alkaline pab tswj kev sib raug zoo nrog ntau yam khoom xyaw ntawm cov tshuaj ntxuav tes.

Txawm hais tias tsis yog txuas ncaj qha rau kev ua tau zoo, cov kev teeb tsa txuj ci tseem ceeb rau kev tsim khoom sib xws thiab kev tswj xyuas zoo. Cov neeg siv khoom raug txhawb kom xaiv cov kev sib xyaw ua ke raws li lawv cov kev xav tau tshwj xeeb ntawm kev ua thiab kev tsim cov qauv. Tus neeg muag khoom txhim khu kev qha tuaj yeem pab los ntawm kev muab kev tshuaj xyuas ntxaws ntxaws thiab kev txhawb nqa kev txawj ntse tas mus li kom ntseeg tau tias kev tsim khoom du thiab kwv yees tau.
