Kev daws rau qhov tsis txaus Magnesium Oxide Purity

Txhim kho cov txheej txheem tiv thaiv kab mob, tau txais kev pov thawj los ntawm thib peb- tog CNAS lub koom haum, thiab hloov siab - cov ntaub ntawv purity yog cov tshuaj tseem ceeb rau kev tsis txaus magnesium oxide purity. Txhawm rau lav tias qhov kev ua tiav kawg ua tiav raws li qhov yuav tsum tau ua, kawg - mus rau - xaus kev tswj hwm los ntawm qhov chaw mus rau qhov khoom kawg yog qhov tseem ceeb.

 

1. Siv High-Purity Raw Materials tam sim ntawd (Kev ntsuas qhov tseem ceeb)

Siv magnesium oxide hmoov uas tsawg kawg yog 99.9% ntshiab thiab muaj tsawg heev cov kab mob loj.

Fe2O3 Tsawg dua lossis sib npaug rau 0.05%

CaO <0.2%

Cl⁻ <0.02%

SO₄²⁻ Tsawg dua lossis sib npaug li 0.1%

Cov neeg muag khoom pom zoo:

99.95% siab -purity magnesium oxide yog muab los ntawm Liaoning Jiashun Technology.

Dashiqiao Meier Magnesium Cov Khoom (HG / T 3928-2012 tus qauv sib xws)

Ua ntej khaws cov khoom siv raw khoom, luam theej duab thiab taug qab lawv kom tsis txhob sib xyaw nrog cov hmoov ntub lossis qis -purity hmoov.

 

2. Thaum lub sij hawm rov ua haujlwm, txhim kho kev tswj cov pa phem

Kev Tswj Xyuas Txheej Txheem

Environmental Control: Kom tsis txhob muaj plua plav paug thiab nqus dej noo, ua haujlwm hauv chav huv nrog RH Tsawg dua lossis sib npaug li 30%.

Cov Khoom Siv Tu: Ua ntej txhua qhov kev siv, siv high -purity nitrogen los ntxuav cov filling thiab sintering khoom.

Kev tiv thaiv huab cua: Thaum lub sij hawm sintering txheej txheem, siab -purity nitrogen (Ntau tshaj los yog sib npaug rau 99.99%) yog ntxiv; cov pa oxygen tsawg dua 100 feem ntawm ib lab. Txhawm rau tiv thaiv kom tsis txhob muaj kab mob los ntawm huab cua noo noo thiab particle teeb meem, hmoov hloov mus rau hauv qhov chaw qhib yog nruj me ntsis txwv.

 

3. CNAS Kev Ntsuam Xyuas thiab Kev Tshawb Fawb los ntawm Cov Neeg Thib Peb (Qhov Kev Pov Hwm Zoo Kawg)

Txhawm rau lav cov ntaub ntawv tsis ncaj ncees thiab kev taug qab, cov qauv yuav tsum raug xa mus rau lwm lub koom haum thib peb - tau tso cai los ntawm CNAS rau kev kuaj pom zoo tom qab rov ua haujlwm dua.

Pom zoo kuaj chaw:

Zhongxi Testing (txhawb ntau tshaj 22 impurity xeem, lub teb chaws tus qauv xa)

Wuhan Kehai Kev Tshawb Fawb Co., Ltd.

Wuhan ceg ntawm Guangfen Testing & Certification Co., Ltd. (nrog rau qhov tseem ceeb ntawm siab -purity khoom tsom xam)

Cov khoom xeem tseem ceeb:

Cov ntsiab lus ntawm MgO Ntau dua lossis sib npaug li 95%

Ntau dua lossis sib npaug li 60% ntawm cov khoom siv magnesium oxide

Insoluble tshuaj nyob rau hauv hydrochloric acid Tsawg dua los yog sib npaug rau 0.5%

Raws li lub hauv paus kev cai lij choj rau kev tso tawm kom zoo, cov ntawv ceeb toom nrog qhov poob ntawm qhov hluav taws xob tsawg dua 5% yuav tsum muaj cov cim CNAS.

 

4. Tsim cov ntaub ntawv kom puv -Txoj kev Traceability

Txhua batch ntawm workpieces uas xa rov qab yuav muaj ib tug txawv coded ntaub ntawv uas txuas nrog:

batch ntawm raw khoom

Kub nkhaus rau sintering

Cov ntaub ntawv ntawm huab cua

Kev kuaj pom

Los ntawm kev ua tiav kaw -kev tswj lub voj voog ntawm kev ua tiav tag nrho- los ntawm cov khoom siv raw mus rau cov khoom tiav- qhov no txhawb kev txhim kho txuas ntxiv thiab teeb meem traceability.
