*Usetyenziso lweMveliso:
Isetyenziswa kwiiprojekthi zogcino lwamanzi, iitanki ze-oyile ekrwada, ukubola kwemichiza ngokubanzi, iinqanawa, izakhiwo zentsimbi, zonke iintlobo zezakhiwo zekhonkrithi ezikwaziyo ukumelana nokukhanya kwelanga.
*Ipeyinti ehambelanayo:
Isetyenziswa kwiiprojekthi zogcino lwamanzi, iitanki ze-oyile ekrwada, ukubola kwemichiza ngokubanzi, iinqanawa, izakhiwo zentsimbi, zonke iintlobo zezakhiwo zekhonkrithi ezikwaziyo ukumelana nokukhanya kwelanga.
*Unyango lomphezulu:
Umphezulu we-primer kufuneka ucoceke, wome kwaye ungangcolisi.Nceda ubeke ingqalelo kwixesha lokwaleka phakathi kolwakhiwo kunye ne-primer.
*Umqathango woKwakha:
Iqondo lobushushu lesubstrate alikho ngaphantsi kwe-5 ℃, kwaye ubuncinane yi-3 ℃ ngaphezulu kweqondo lombethe lomoya, kunye nokufuma okuhambelanayo ngu <85% (ubushushu kunye nokufuma okuhambelanayo kufuneka kulinganiswe kufuphi ne-substrate).Ulwakhiwo aluvumelekanga ngokungqongqo kwinkungu, imvula, ikhephu, kunye nemozulu enomoya.
Gcoba kwangaphambili i-primer kunye nepeyinti ephakathi, kwaye uyomise umkhiqizo emva kweeyure ezingama-24.Inkqubo yokutshiza isetyenziselwa ukutshiza amaxesha angama-1-2 ukufezekisa ubukhulu befilimu obuchaziweyo, kunye nobukhulu obucetyiswayo ngu-60 μm.Emva kokwakhiwa, ifilimu yepeyinti kufuneka ihambe kakuhle kwaye ibe tyaba, kwaye umbala kufuneka uhambelane, kwaye akufanele kubekho ukugoqa, ukuqhuma, i-orange peel kunye nezinye izifo zepeyinti.
*Iiparamitha zoKwakha:
Ixesha lokunyanga: imizuzu engama-30 (23 ° C)
Ubomi bonke:
| Ubushushu,℃ | 5 | 10 | 20 | 30 |
| Ubomi bonke (h) | 10 | 8 | 6 | 6 |
Idosi encinci (umlinganiselo wobunzima):
| Ukutshiza okungenamoya | Ukutshiza ngomoya | Ibrashi okanye i-roll coating |
| 0-5% | 5-15% | 0-5% |
Ixesha lokwaleka (ubukhulu befilimu nganye eyomileyo ngama-35um):
| Ubushushu be-Ambient, ℃ | 10 | 20 | 30 |
| Elona xesha lifutshane, h | 24 | 16 | 10 |
| Ixesha elide kakhulu, usuku | 7 | 3 | 3 |
*Indlela yokwakha:
Ukutshiza: Ukutshiza okungekho moya okanye ukutshiza ngomoya.Kucetyiswa ukusetyenziswa koxinzelelo oluphezulu ngaphandle kokutshiza ngegesi.
Ibrashi / umqulu wokugquma: kufuneka ufezekise ubungakanani obuchaziweyo befilimu eyomileyo.
*Amanyathelo okhuseleko:
Nceda uqaphele zonke iimpawu zokhuseleko kwipakethe ngexesha lokuthutha, ukugcinwa kunye nokusetyenziswa.Thatha amanyathelo ayimfuneko okuthintela nokukhusela, ukuthintela umlilo, ukukhuselwa kogqabhuko-dubulo kunye nokukhuselwa kwendalo.Kuphephe ukuphefumla imiphunga enyibilikayo, kuphephe ukudibana nesikhumba namehlo ngepeyinti.Musa ukuginya le mveliso.Kwimeko yengozi, funa unyango ngokukhawuleza.Ukulahlwa kwenkunkuma kufuneka kuhambelane nemigaqo yokhuseleko yesizwe neyengingqi.
*Ipakethi:
Ipeyinti: 20Kg/Emele;
I-Arhente yokuNyanga/isiQhaqili:4Kg/Ibhakethi
ipeyinti:i-arhente yokunyanga/ihardener=5:1(umlinganiselo wobunzima)
