1: Yog tias cov menyuam laus, ua ntej kev teeb tsa, koj yuav tsum tshem tawm cov kua nplaum tsis kam, thov siv lub kaum sab xis grinder thiab tungsten steel phaj los txhuam cov menyuam nto, qhov tuab ntawm qhov kev kho polish yog 30um.
2. txhuam cov xab npum rau ntawm qhov chaw polished ntawm cov menyuam, ntxuav cov impurity thiab roj av.
3. Tos kom qhuav ntawm cov tshuaj ntxuav tes, txhuam ib txheej ntawm cov hlau txheej rau ntawm cov menyuam nto kom tsis txhob muaj kev xeb los ntawm cov txheej txheem sab nraud.
4. Sib tov cov kua nplaum txias SK313, tom qab ntawd txhuam cov nplaum rau ntawm cov menyuam nto, tom qab kho, txhuam ntau txheej SK313 ntawm cov menyuam dua, lub sijhawm txhuam ib txheej SK313 ntawm lub nraub qaum xiav ntawm cov roj hmab ceramic liner.
5. Thaum cov nplaum nplaum me ntsis rau cov ntiv tes, thov muab cov roj hmab ceramic liner rau ntawm qhov chaw ntawm cov menyuam, thiab siv cov roj hmab rauj ntaus sib xyaw kom nruj, thaum kawg muab cov roj hmab kho tus neeg sawv cev rau hauv qhov chaw ntawm qhov sib koom ntawm cov roj hmab ceramic liner. rau kev kho sealing.
