Cov Txheej Txheem Ntau Lawm Ntawm Dawb Corundum Sib Tsoo Hmoov
Kev ua haujlwmdawb corundum grinding powder, we must first choose the raw materials. The raw material should be the core protection material of the abrasive wheel factory, the crystal contains >=98.5%, qhov loj me yog 36#, 46#, 100#, thiab cov ntsiab lus ntawm SiO2 hauv cov khoom siv raw yuav tsum tsawg li tsawg tau. Cov cuab yeej siv yog pob zeb, iav lub tog raj kheej, kub kub tiv thaiv hluav taws xob, khoom siv hluav taws xob, kev ntxuav trough thiab lub tshuab ua pa.
Kev piav qhia ntawm kev siv tshuab ntawm dawb corundum sib tsoo hmoov:
1. Crush. Muab ib pawg ntawm quenched steel npas ntawm txawv diameters rau hauv cov menyuam nrog tib cov khoom siv raw, ntxiv dej, muab tso rau hauv cov roj hmab ncoo thiab kaw lub hau, thiab tom qab ntawd ua rau cov menyuam tig, thiab cov abrasive yog crushed nyob rau hauv kev cuam tshuam ntawm cov hlau. pob. Pulverizing 1 kg ntawm raw cov ntaub ntawv yuav tsum muaj ib tug tag nrho hnyav ntawm txog 3 kg ntawm steel pob.
2. Pickling thiab ntxuav. Lub hom phiaj yog los ntxuav cov hlau impurities tawm ntawm abrasive.
3. Kev txheeb xyuas. Kev sib cais tau ua nyob rau hauv lub khob lub tog raj kheej los ntawm txoj kev sib cais dej. Qhov hnyav piv ntawm dej mus rau dawb corundum sib tsoo hmoov yog roughly 10-16: 1.
4. Qhuav. Qhuav nyob rau hauv qhov cub ntawm 100-200 degrees Celsius, thiab grind lub clumps zoo nrog ib tug iav pestle los yog horn diav tom qab ziab.
5. Satinaki. Muab cov hmoov dawb corundum sib tsoo rau hauv lub cub hluav taws xob lossis Muffle rauv, los ntawm qhov kub ib txwm mus rau 850 degrees, rau w0.5-W1 dawb corundum sib tsoo hmoov qee zaum txog 1200 degrees, thiab tom qab ntawd kub rau 5. teev.
6. Npog. Cov abrasives siv rau hauv kev sib tsoo thiab polishing tiav yuav tsum tau tsau. Soaking yuav tsum yog: 0.4 grams stearic acid ntxiv rau 20 grams ntawm cov hmoov sib tsoo ntxiv rau 200 ml ntawm cov pa roj av, rau hauv av iav raj mis soaked rau ntau tshaj xya hnub.
