Chinyorwa chekushandisa
Gadzirisa chikamu B yunifomu usati waisa, nyatso sanganisa iwo akaiswa pigment, kana chigadzirwa 'mhando ichakanganiswa.
pfapfaidza polyurea mukati menguva yakafanira kana iyo substrate yepasi yakadhindwa.Kune nzira yekushandisa uye nguva yenguva yeSWD polyurea speical primer ndapota tarisa kune rimwe bhurocha remakambani eSWD.
Gara uchiisa SWD pfapfaidza polyurea panzvimbo diki isati yakakura application kutarisa musanganiswa reshiyo, ruvara uye kupfapfaidza maitiro ndizvo.Kuti uwane ruzivo rwakadzama rwekushandisa ndapota tarisa kune razvino rekuraira bepa reiyo mirayiridzo yekushandisa yeSWD spray polyurea series.
Nguva yekugadzira chigadzirwa
| Substrate tembiricha | Dry | Kufamba nesimba | simbisa zvizere |
| +10 ℃ | 28s | 45min | 7d |
| +20 ℃ | 20s | 15min | 6d |
| +30 ℃ | 17s | 5min | 5d |
Cherechedza: nguva yekurapa inosiyana nemamiriro ekunze kunyanya tembiricha uye hunyoro hunoenderana.
Sherufu Hupenyu
* Kubva pazuva rekugadzira uye pane yekutanga pasuru yakavharwa mamiriro:
Chikamu A: Mwedzi gumi
Chikamu B: Mwedzi gumi
*kuchengetera tembiricha:+5-35°C
Kurongedza: Chikamu A 210kg / chigubhu, chikamu B 200kg / chigubhu
Ita shuwa kuti chigadzirwa pasuru yakavharwa zvakanaka.
* chengeta munzvimbo inotonhorera uye inofefetera, dzivirira kuratidzwa kwezuva kwakananga.
