Self Dry Silver Top Coat JH-9320

Yathu ya zinc flake zokutira pamwamba kuuma ndi otsika, zolakwika pakupaka ndi asidi ndi alkali kugonjetsedwa, tengerani maphunziro kuchokera kuukadaulo waukadaulo wapanyumba, kafukufuku wapamwamba kwambiri wa zida zopangira ndi kupanga JH-9320 zinc flake zokutira zapadera zowuma zowuma zamadzimadzi, zonse zimawonjezeka. Zinc flake ❖ kuyanika pamwamba kuuma, asidi ndi alkali kukana, ndipo akhoza kusintha ntchito anticorrosion wa ❖ kuyanika ndi nthaka flake ❖ kuyanika kuyanjana kwabwino kumamatira.
Chofunikira chachikulu ndi madzi-base inorganic silika , wosakanikirana ndi corrosion protection assistant. Mtengo wa mankhwala ndi wotsika.

Malangizo ndi chidwi:
1. Dip ❖ kuyanika, Utsi ❖ kuyanika etc;
2. Iyenera kugwedezeka mokwanira kuti igwiritsidwe ntchito;madzi osungunuka kapena madzi osungunuka angagwiritsidwe ntchito kusintha kukhuthala;Kugwira ntchito mamasukidwe akayendedwe: 30-60s.
3. Pamene chilengedwe chinyezi kuposa 85%, akhoza kuwonjezera mowa wina mafakitale kusintha mamasukidwe akayendedwe;
4. Kuchiritsa chikhalidwe: 80 ℃/10min+140℃/30min;
5. Chida choyeretsera: madzi oyenda amatha kugwiritsidwa ntchito;
6. Pewani asidi zinthu, kapena polymerization ndi kuwonongeka zidzachitika;
7. Mankhwalawa angagwiritsidwe ntchito okha, mafuta ophimbidwa pamwamba amapempha mafuta, opanda fumbi ndi owuma, ndi bwino kupanga mankhwala a degreasing, derusting, ndi phosphating.
