Ububanzi besicelo
Isalathiso sokwakha
1, Umphezulu wezinto ezigqunyiweyo kufuneka ungabi na-oxide, umhlwa, ioyile njalo njalo.
2, Ubushushu be-substrate kufuneka bube ngaphezulu kwe-3 ° C ngaphezu kwe-zero, xa ubushushu be-substrate bungaphantsi kwe-5 ° C, ifilimu yepeyinti ayiqinanga, ngoko ke ayifanelekanga ukwakhiwa.
3, Emva kokuvula ibhakethi yecandelo A, kufuneka ixutywe ngokulinganayo, uze ugalele iqela B kwicandelo A phantsi uxube ngokwemfuneko yomlinganiselo, uxutywe ngokupheleleyo ngokulinganayo, ume, kwaye uqine. Emva kwemizuzu engama-30, yongeza isixa esifanelekileyo se-diluent kwaye ulungelelanise i-viscosity yokwakha.
4, Ipeyinti isetyenziswa ngokupheleleyo kwiiyure ezi-6 emva kokuxuba.
5, Ibrashi yokugquma, ukutshiza ngomoya, ukugquma okuqengqelekayo kunokuba njalo.
6, Inkqubo yokugquma kufuneka ihlale ixutywa ukuze kuthintelwe imvula.
7, Ixesha lokupeyinta:
| Ubushushu be-substrate (°C) | 5~10 | 15~20 | 25~30 |
| Ixesha elincinci (Iyure) | 48 | 24 | 12 |
Ixesha eliphezulu akufuneki lidlule kwiintsuku ezisi-7.
8, ubukhulu befilimu obucetyiswayo: 60~80 microns.
9, idosi: 0.2 ~ 0.25 kg ngesikwere ngasinye (ngaphandle kokulahlekelwa).
Phawula
1, Umlinganiselo we-Diluent kunye ne-dilution: i-inorganic zinc-rich anti-rust primer ekhethekileyo enciphileyo 3% ~ 5%.
2, Ixesha lokunyanga: 23±2°C imizuzu engama-20. Ixesha lokufaka: 23±2°C iiyure ezi-8. Ixesha lokufaka: 23±2°C ubuncinci iiyure ezi-5, ubuninzi beentsuku ezi-7.
3, Unyango lomphezulu: umphezulu wentsimbi kufuneka ususwe ngumsi nge-grinder okanye nge-sandblasting, ukuze i-Sweden igrust Sa2.5.
4, Kucetyiswa ukuba inani leetshaneli zokugquma: 2 ~ 3, kulwakhiwo, ukusetyenziswa komxube wombane wokulifti kuya kuba yi-Component (slurry) exutywe ngokupheleleyo ngokulinganayo, kufuneka isetyenziswe ngelixa kuxutywa ulwakhiwo. Emva kokuxhasa: zonke iintlobo zepeyinti ephakathi kunye nepeyinti ephezulu eveliswe ngumzi-mveliso wethu.
Uthutho kunye nokugcinwa
1, i-primer etyebileyo ye-Epoxy zinc ekuthuthweni, kufuneka ithintele imvula, ukukhanya kwelanga, ukuze kuthintelwe ukungqubana.
2, I-primer etyebileyo ye-Epoxy zinc kufuneka igcinwe kwindawo epholileyo nengena umoya, ithintele ukukhanya kwelanga ngqo, kwaye yahlukanise umthombo womlilo, kude nomthombo wobushushu kwindawo yokugcina impahla.
