Vazhinji vanotanga vanowira mumusungo pavanenge vachitenga mavara akavharirwa rolls nekuti havanzwisise zvinhu zvavo. Saka, ndezvipi zvinhu zvakanaka kune mavara akafukidzwa rolls?
Iyo substrate yemavara akaputirwa makoiri anogona kutonhora-akakungurutswa makoiri kana inopisa-dhip electroplated simbi. Kunyangwe iyo organic kupfekedzwa kwemavara coil zvinhu zvine yakanaka anti-corrosion mhedzisiro, kuchine mamwe madiki madiki mu organic coating, izvo zvinogona kubvumira mweya nehunyoro kupinda uye kukonzera ngura kweiyo substrate. Naizvozvo, macoil ane mavara akavharwa akagadzirwa kubva kune asina kuvharwa substrates ane hupenyu hupfupi hwesevhisi uye anowanzo kupararira uye kupeta kupepeta mushure mekukweshwa. Iyo substrate yeruvara yakavharwa simbi coil inonyanya kuve yakabatiswa simbi ndiro kana galvanized simbi alloy yesimbi plate tekinoroji. Mune mamwe mitsara yekugadzira, maitiro ekugadzirwa kwemavara ekuputira akakamurwa kuita substrate pre-kurapa, makemikari ekushandura coatings (asiri organic simbi coatings), organic isiri-metallic coatings, uye post coating maitiro.
1, Substrate pre-treatment: Kana isu tisiri kambani inogona kupinda zvakanangana nerudzi rwekupfekedza nharaunda mushure mekugadzirwa, marata esimbi mahwendefa anoshandiswa se substrates anogona kuramba achiita ngura (chena ngura), guruva, uye kumwe kusvibiswa panguva yekufambisa nekusimudzira. . Kana izvi zvisingakwanisi kubviswa, hutano hwepende huchakanganiswa. Hunhu hweakapedzwa mavara akaputirwa rolls uye yemuviri uye kemikari tekinoroji kuita kwevadzidzi vese zvine hukama ne pre-kurapa. Uye zvakare, mukugadzira galvanizing, kuitira kudzivirira ngura uye oiri, mafuta aya anobviswa zvakare pamberi pekugadzirwa kwemavara. Iyo inowanzo shandiswa pre-kurapwa nzira ikozvino ndiyo alkaline solution degreasing nzira.
2. Iyo kemikari yekushandura firimu ine mabasa maviri
Imwe ndeyekuwedzera kuvandudza kugona kwekudzivirira ngura,
Chechipiri ndechekuvandudza kusungirirwa pakati pe substrate uye kupfeka, uye kuvandudza kushanda kwekuvhara kwe substrate.
Kazhinji pane matanho matatu:
Imwe iphosphating, iyo inotanga kuumba makristasi akawanda pamusoro pesimbi, uye inoumba chidimbu chefirimu yephosphate pamusoro pesimbi ine phosphate salt solution;
Yechipiri ndeye passivation uye kuisa chisimbiso. Iyo phosphate film ichine mamwe ma pores, ayo anogadzirwa nemakemikari nemakromati kuti aite firimu rinodzivirira. Chechitatu, geza nemvura yakachena uye bvisa passivation solution nemvura yakasvibiswa kana yakasvibiswa.
3, Organic coatings inonyanya kukamurwa kuita primer uye topcoat. Zvido zvePrimer hazvina kukwirira uye zvinogona kuiswa zvine ruvara rwakatsetseka. Nekudaro, kuti uvandudze kuchengetedzwa kweruzivo rwekugadzira, mabhizinesi eChinese anowanzo shandisa nzira yekudzosera reverse yekubikira yeprimer uye topcoat.
Post coating process: Iyo post coating process inosanganisira kudhinda, embossing, peelable inodzivirira firimu, bonding, nezvimwe, izvo zvinovandudza kushongedza uye kudzivirira zvimiro zveruvara rakaputirwa bhodhi.
