Tus yuam sij rau kev txhim kho cov purity ntawm reworked magnesium oxide yog siv high -purity raw cov ntaub ntawv (Ntau tshaj los yog sib npaug rau 99.9%), sinter nyob rau hauv nitrogen tiv thaiv nyob rau hauv tag nrho cov txheej txheem, thiab kom nws kuaj thiab xyuas los ntawm ib tug CNAS - ntawv pov thawj lub koom haum. Kev kis kab mob lossis kev ua haujlwm tsis zoo ntawm txhua theem yuav cuam tshuam ncaj qha rau qhov kawg purity.
1. Kev tswj xyuas nruj ntawm Raw Material Purity (Tau qhov twg los lav)
Siv siab -purity magnesium oxide hmoov: Yuav tsum ua kom muaj ntau dua lossis sib npaug rau 99.9% purity, nrog cov impurities tseem ceeb txwv nruj:
Fe₂O₃ Tsawg dua lossis sib npaug rau 0.05%
CaO Tsawg dua lossis sib npaug li 0.2%
Cl⁻ Tsawg dua lossis sib npaug rau 0.02%
SO₄²⁻ Tsawg dua lossis sib npaug li 0.1%
Cov neeg muab khoom pom zoo:
Liaoning Jiashun Technology (muab 99.95% siab -purity magnesium oxide)
Dashiqiao Meier Magnesium Cov Khoom (ua raws li HG / T 3928-2012 tus qauv)
Cov ntaub ntawv batch yuav tsum tau tshuaj xyuas thiab tshawb xyuas ua ntej cov khoom siv raw nkag mus rau hauv lub tsev khaws khoom kom tsis txhob muaj qhov sib xyaw ntawm cov khoom tsis muaj -purity lossis cov hmoov ntub dej.
2. Txhim kho cov txheej txheem rov ua haujlwm kom zoo tiv thaiv kab mob (txheej txheem tswj)
Kauj Ruam Cov Ntsiab Lus
Kev Tswj Ib puag ncig: Ua haujlwm hauv chav huv nrog RH Tsawg dua lossis sib npaug li 30% txhawm rau tiv thaiv kev nqus dej thiab plua plav paug.
Cov Khoom Siv Tu: Tshem tawm cov khoom ntim thiab sintering nrog siab -purity nitrogen ua ntej siv.
Kev tiv thaiv huab cua: Ua kom siab -purity nitrogen cua (Ntau dua lossis sib npaug li 99.99%) thoob plaws hauv cov txheej txheem sintering; oxygen cov ntsiab lus <100 ppm.
Powder Transfer: Qhib-kev ua haujlwm ib puag ncig yog txwv nruj kom tsis txhob muaj kab mob los ntawm huab cua ya raws thiab cov khoom me me.
Kev tiv thaiv nitrogen yog qhov tseem ceeb los tiv thaiv oxidation thiab carbonization tshwm sim; Cov ntsiab lus oxygen yuav tsum tau saib xyuas hauv lub sijhawm.
3. Thib Peb-Tag Nrho CNAS Kev Xeem thiab Kev Tshawb Fawb (Kev Pom Zoo Pom Zoo): Tom qab rov ua haujlwm dua, cov qauv yuav tsum raug xa mus rau CNAS- tau lees paub thib peb- lub koom haum thib peb rau kev kuaj xyuas kom ntseeg tau cov ntaub ntawv tsis ncaj ncees thiab kev taug qab.
Pom zoo Cov Tsev Kawm Ntawv Xeem:
Zhongxi Kev Xeem (Txhim kho 22+ kev xeem impurity, kev xa tawm thoob tebchaws)
Wuhan Kehai Inspection Co., Ltd.
Guangfen Testing & Certification Co., Ltd. (Wuhan ceg) (Tsom rau siab -purity khoom tsom xam)
Yuav tsum tau xeem yam khoom:
MgO cov ntsiab lus Ntau dua lossis sib npaug rau 95%
Active magnesium oxide Ntau dua lossis sib npaug li 60%
Hydrochloric acid insoluble teeb meem Tsawg dua los yog sib npaug rau 0.5%
Kev poob ntawm qhov hluav taws kub tsawg dua lossis sib npaug li 5% Cov ntawv ceeb toom yuav tsum dais CMA / CNAS cim raws li kev cai lij choj rau kev tso tawm zoo.
4. Tsim kom muaj tag nrho -Cov ntaub ntawv taug qab taug qab
Txhua batch ntawm rov qab workpieces yuav muaj ib tug cim coded ntaub ntawv, txuas mus rau:
Raw khoom batch
Sintering kub nkhaus
Cov ntaub ntawv huab cua
Daim ntawv xeem
Qhov no ua tiav kev kaw- kev tswj lub voj voog ntawm tag nrho lub neej voj voog los ntawm cov khoom siv raw mus rau cov khoom tiav, ua kom muaj teeb meem traceability thiab txhim kho txuas ntxiv.
