Masitepe ena ofunikira pakuponyera mwatsatanetsatane!

Mwatsatanetsatane kuponyera ndi njira yodziwika yoponyera opanga opanga zitsulo, koma chitukuko chamakono sichiri chofala ngati kuponyera kwazitsulo ndi kuponyera kwazitsulo, koma kuponyera mwatsatanetsatane kumatha kupeza mawonekedwe olondola komanso kuponyera mwatsatanetsatane.

Njira yodziwika bwino yoponyera mwatsatanetsatane ndikupanga nkhungu za mankhwala malinga ndi zojambulazo. Kusiyanitsa pakati kuponyera mwatsatanetsatane ndi kuponyera kwazitsulo ndikuti kuponyera kwazitsulo kuyenera kukhala ndi malire ena kuti akonzedwe, pomwe kuponyera mwatsatanetsatane kumatha kukhala ndi malire kapena ayi. pa sera sera. Chigoba cholimbacho chikauma, sera ya mkati isungunuka. Gawo ili ndilopunduka, kuti tipeze zibowo; Tikaphika chipolopolo, titha kupeza mphamvu zokwanira komanso kuloleza kwa mpweya. Kenako titha kuponya madzi ofunikira achitsulo m'mimbamo. Pambuyo pozizira, titha kuchotsa chipolopolocho ndikuchotsa mchenga, kuti tipeze zopangira zolondola kwambiri.Titha kuchita chithandizo chazakudya kapena kuzizira malinga ndi zosowa za malonda.

Njira zoponya ndalama:

1. Malinga ndi zofunikira za zojambula za wogwiritsa ntchito, nkhunguyo imagawika kumtunda wakumunsi ndi wotsika wa concave, womwe umamalizidwa ndi kugaya, kutembenuka, kukwera ndege ndi njira zina. Maonekedwe a dzenje la nkhungu amayenera kukhala ogwirizana ndi theka la zopangidwazo.Pakuti nkhungu ya sera imagwiritsidwa ntchito popanga sera ya mafakitale, tifunika kusankha zinthu za aluminium alloy zolimba, zosafunikira, mtengo wotsika, kulemera pang'ono komanso kutsika limatsogolera mfundo monga nkhungu.

2. Pambuyo posankha zinthu zabwino za aluminium alloy, titha kugwiritsa ntchito aloyi zotayidwa kuti tipeze mitundu yambiri ya sera yolimba yamafuta.

3. Pamene sera ikonzeka, m'pofunika kusintha malire mozungulira sera. Pambuyo pochotsa zinthu zosafunika pamwamba, ndikofunikira kumata sera imodzi pamutu wokonzeka.

4. Tili ndi sera ya phula yambiri yokutidwa ndi guluu wopangidwa ndi mafakitale, kenako kenako tidapopera ndi gawo loyamba la mchenga wa silika wosagwira moto komanso wotentha kwambiri.Mtundu uwu wamchenga wamchenga ndi wocheperako komanso wabwino, womwe ungatsimikizire kuti Pamapeto pake pazikhala zopanda pake.

5. Kenako ikani phula mu fakitole momwe timayika kutentha kwa chipinda, koma sichiyenera kusintha mawonekedwe a sera mkati. Nthawi yowumitsa mpweya mwachilengedwe imadalira momwe mkati mwake mulili zovuta. Nthawi zambiri, nthawi yoyamba kuyanika mpweya ndi pafupifupi maola 5-8.

6. Sera ikamauma mpweya, guluu wa zomatira umafunika pamwamba pa sera, ndipo mchenga wachiwiri umawazidwa pamwamba pake. Mchenga wa m'chigawo chachiwiri ndi wokulirapo komanso wolimba kuposa uja woyamba. Mukakhudza mchenga wachiwiri, monga woyamba, umayanika mwachilengedwe

7. Pambuyo pa mchenga wachiwiri mchenga mwouma mwachilengedwe, wosanjikiza wachitatu, wosanjikiza wachinayi ndi wachisanu wosanjikiza mchenga udzachitika motsatizana.Sandblasting zofunika: tifunika kusintha nthawi za sandblasting malingana ndi zofunikira zapadziko lapansi ndi kuchuluka kwa Kawirikawiri, kuchuluka kwa sandblasting kumakhala pafupifupi 3-7 nthawi. Tinthu tating'onoting'ono tomwe timakhala ndi mchenga wosiyana ndi tina, mchenga wa chilichonse umakhala wolimba kuposa wakale, ndipo nthawi yowumitsa mpweya ndiyosiyana. nthawi yomanga mchenga pamtambo wathunthu wa sera itha kukhala masiku 3-4
