*Ukusetyenziswa kweMveliso:
Isetyenziswa kwiiprojekthi zokugcina amanzi, iitanki zeoyile ekrwada, ukubola kweekhemikhali ngokubanzi, iinqanawa, izakhiwo zentsimbi, zonke iintlobo zezakhiwo zekhonkrithi ezingamelaniyo nelanga.
*Ipeyinti Ehambelanayo:
Isetyenziswa kwiiprojekthi zokugcina amanzi, iitanki zeoyile ekrwada, ukubola kweekhemikhali ngokubanzi, iinqanawa, izakhiwo zentsimbi, zonke iintlobo zezakhiwo zekhonkrithi ezingamelaniyo nelanga.
*Unyango Lomphezulu:
Umphezulu weprimer kufuneka ucoceke, wome kwaye ungabi nangcoliseko.
Nceda uqaphele isithuba sokwaleka phakathi kolwakhiwo kunye neprimer.
*Imeko yoKwakha:
Ubushushu be-substrate abukho ngaphantsi kwe-5 ℃, kwaye ubuncinane bube ngaphezulu kwe-3 ℃ kunobushushu be-air dew point, kwaye umswakama ohambelanayo ungaphantsi kwe-85% (ubushushu kunye nomswakama ohambelanayo kufuneka kulinganiswe kufutshane ne-substrate). Ukwakhiwa akuvumelekanga ngokungqongqo kwinkungu, imvula, ikhephu, kunye nemozulu enomoya.
Gcoba ipeyinti yokuqala kunye nepeyinti ephakathi, uze womise imveliso emva kweeyure ezingama-24. Inkqubo yokutshiza isetyenziselwa ukutshiza izihlandlo ezi-1-2 ukuze kufikelelwe kubukhulu befilimu obuchaziweyo, kwaye ubukhulu obucetyiswayo yi-60 μm. Emva kokwakhiwa, ifilimu yepeyinti kufuneka ibe bushelelezi kwaye ithe tyaba, kwaye umbala kufuneka ulingane, kwaye akufuneki kubekho ukugoba, ukudumba, amaxolo eorenji kunye nezinye izifo zepeyinti.
*Iiparameter zoLwakhiwo:
Ixesha lokunyanga: imizuzu engama-30 (23 ° C)
Ubomi bonke:
| Ubushushu, ℃ | 5 | 10 | 20 | 30 |
| Ubomi bonke (h) | 10 | 8 | 6 | 6 |
Umlinganiselo wobunzima obuncinci (umlinganiselo wobunzima):
| Ukutshiza Okungenamoya | Ukutshiza ngomoya | Ibrashi okanye i-roll coating |
| 0-5% | 5-15% | 0-5% |
Ixesha lokuphinda ufake i-coating (ubude befilimu nganye eyomileyo yi-35um):
| Ubushushu obuphakathi, ℃ | 10 | 20 | 30 |
| Ixesha elifutshane, h | 24 | 16 | 10 |
| Ixesha elide, usuku | 7 | 3 | 3 |
*Indlela yokwakha:
Ukutshiza: ukutshiza ngaphandle komoya okanye ukutshiza ngomoya. Kucetyiswa ukuba kusetyenziswe ukutshiza ngaphandle komoya ngoxinzelelo oluphezulu.
Ingubo yokugquma ngebrashi/ngokuqengqeleka: kufuneka ifikelele kubukhulu obuchaziweyo befilimu eyomileyo.
*Amanyathelo okhuseleko:
Nceda uqaphele zonke iimpawu zokhuseleko ezikwiphakheji ngexesha lokuthuthwa, ukugcinwa kunye nokusetyenziswa.
Thatha amanyathelo okukhusela nawokuthintela ayimfuneko, ukuthintela umlilo, ukhuseleko lokuqhuma kunye nokhuseleko lokusingqongileyo.
Kuphephe ukuphefumla umphunga onyibilikisayo, kuphephe ukudibana nolusu namehlo ngepeyinti.
Musa ukuyiginya le mveliso.
Xa kwenzeka ingozi, funa uncedo lwezonyango ngokukhawuleza.
Ukulahlwa kwenkunkuma kufuneka kuhambelane nemigaqo yokhuseleko karhulumente wesizwe nowengingqi.
*Iphakheji:
Ipeyinti: 20Kg/Ibhakethi;
Iarhente yokuphilisa/iHardener: 4Kg/Ibhakethi
ipeyinti: iarhente yokuphilisa/i-hardener = 5:1 (umlinganiselo wobunzima)
