Chowonjezera cha Chromium

2. Gwiritsani ntchito zinthu:

2.1 Kuwonjezera kutentha: ≥730°C.

2.2 Mlingo wamankhwala wamtunduwu umawerengedwa motsatira njira iyi:

Zindikirani: Chifukwa cha kusiyana kwa ogwiritsa ntchito ndi zitsulo mu ng'anjo, ndalama zenizeni zowonjezera ziyenera kuwerengedwa ndikutsimikiziridwa potengera deta yoyesera pamaso pa ng'anjo.

2.3 Njira yowonjezera:

Mukasungunuka mu ng'anjo, gwedezani mofanana, tengani chitsanzo ndikusanthula kuti muwerenge kuchuluka kwa chromium wothandizira.Pamene kutentha kwasungunuka kukufika, chotsani zinyalala pamwamba pa kusungunuka, ndi kumwaza mankhwalawo m'madera osiyanasiyana a dziwe losungunuka (ngati kuli kofunikira kuwonjezera manganese ndi mkuwa wothandizira, akhoza kuwonjezeredwa nthawi imodzi).Zomwezo zikatha, imirirani kwa mphindi 10-20, kenako ndikuyambitsanso kwa mphindi zisanu;imiriraninso kwa mphindi 5-10, ndipo tengani chitsanzo kuti muwunike;Zosakaniza zokhazokha ndizoyenerera ndiye zikhoza kusamutsidwa ku ndondomeko yotsatira.

3. Kuyika ndi kusunga:

Chogulitsachi ndi chozungulira chozungulira ngati keke yakuda imvi, mkati mwake ndi thumba la pulasitiki / vacuum bag / aluminium zojambulazo;ma CD akunja ndi makatoni;500g / chidutswa, 2.5kg / thumba, 20kg / bokosi.Kusunga mu mpweya wokwanira ndi malo ouma, kutali ndi chinyezi.

4. Moyo wa alumali

Miyezi isanu ndi itatu, angagwiritse ntchito mwachindunji mutatsegula bokosi.
