Mitundu ya lamba wa mchenga oyenera kupukuta mipando ndikupera
Nthawi zambiri, mchenga wokhala ndi mchenga wokulirapo (monga 240#, 320#, ndi zina zotero) umagwiritsidwa ntchito popanga mchenga motsatira mbali ya njere zamatabwa, ndipo sungakhoze kumangidwa mopingasa kapena mosadukiza kuti upewe kusiya ming'alu ya mchenga.Popukuta billet yoyera, m'pofunikanso kumvetsera mbali zowonongeka monga mizere ndi ngodya zamalata kuti zisawonongeke kapena zowonongeka, kuti zisakhudze mawonekedwe osalala ndi okongola a mizere ndi ngodya zamalata.
Nthawi zambiri, mafakitale opanga mipando amagwiritsa ntchito makina akuluakulu amalamba.Malinga ndi zofunikira za kupukuta pamwamba, sankhani lamba wopangira ntchito, kuyambira 240 mpaka 800, ndipo mfundo yabwino kwambiri ndi 1000, koma malamba otsekemera oterewa sagwiritsidwa ntchito kawirikawiri.
Zofunikira zopukuta ndi zosalala komanso zopanda chilema, ndipo mizere yopukutidwa iyenera kugwirizana ndi mizere yoyera yopanda kanthu.Choncho, midadada yamatabwa ndi mapepala ena nthawi zambiri amagwiritsidwa ntchito popukuta nkhope zowongoka.Mukapukuta putty mu zokutira zowonekera, samalani ndi kupukuta putty yozungulira monga ming'alu, mabowo a misomali, ndi zina zotero, osasiya zizindikiro.
Kupukuta kwa ❖ kuyanika wapakatikati (amatchedwanso interlayer kupukuta) akhoza kuchotsa fumbi particles pa filimu pamwamba, thovu, mizere lalanje, ndi sagging chifukwa cha ntchito yosayenera, komanso kuonjezera adhesion pakati zokutira.Pakuti mchenga pakati zigawo, mukhoza kusankha 320#—600# sandpaper malinga ndi zosowa zanu.Zofunikira zamtundu ndi zosalala, palibe nyenyezi zowala, ndipo palibe mchenga momwe mungathere, ndipo pamwamba pake ndi galasi.
Mawonekedwe:
Ma abrasives a bulauni ophatikizika a alumina, nsalu yoyera ya thonje, mchenga wodzala ndi kachulukidwe kakang'ono, nsalu ya emery imakhala ndi zowonjezera zazing'ono, zoyenera mitundu yosiyanasiyana ya malamba amchenga.
Amagwiritsidwa ntchito makamaka mu:
Mitengo ya paini, matabwa a matabwa, mipando, zinthu zopangidwa ndi manja, zinthu za rattan, zojambula zazitsulo zambiri.

Mawonekedwe:
Silicon carbide abrasives, nsalu zosakanikirana, mchenga wodzala wandiweyani, uli ndi ntchito yokana madzi ndi mafuta.Itha kugwiritsidwa ntchito mowuma komanso yonyowa, ndipo zoziziritsa kukhosi zitha kuwonjezeredwa.Ndi yoyenera kwa mitundu yosiyanasiyana ya malamba a mchenga.
Amagwiritsidwa ntchito makamaka mu:
Mitundu yonse ya matabwa, mbale, mkuwa, zitsulo, aluminiyamu, galasi, mwala, bolodi lozungulira, laminate yamkuwa, faucet, hardware yaing'ono ndi zitsulo zosiyanasiyana zofewa.
