* Iimpawu zeMveliso:
. Ukuchasana nokuchasana nemichiza kunye nokuxhathisa kwamanzi
. Ukunganyangeki kwii-oyile zeminerali, ioyile yemifuno, izinyibilikisi zepetroli kunye nezinye iimveliso zepetroleum
. Ifilimu yepeyinti inzima kwaye isysys. Ubushushu befilimu, abuthathaka, hayi

* Ukusetyenziswa kwemveliso:
Isetyenziswa kwiiprojekthi zolondolozo lwamanzi, iitanki zeoyile ezityhafileyo, i-comrosion yekhemikhali yekhemikhali, iinqanawa, izakhiwo zentsimbi, zonke iintlobo zezakhiwo zekhonkrithi.
* Ukupeyinta ipeyinti:
Isetyenziswa kwiiprojekthi zolondolozo lwamanzi, iitanki zeoyile ezityhafileyo, i-comrosion yekhemikhali yekhemikhali, iinqanawa, izakhiwo zentsimbi, zonke iintlobo zezakhiwo zekhonkrithi.
* Unyango lomphezulu:
Umphezulu weprimer kufuneka ucoceke, owomileyo nongcoliseko. Nceda unikele ingqalelo kwithuba lokuphatha phakathi kolwakhiwo kunye neprimer.
* Imeko yokwakha:
Iqondo lobushushu le-rightive lingaphantsi kwe-5 ℃, kunye ne-3 ℃ i-3 ℃ i-the hist inqaku lokugcina iqondo lokugcina, kunye nomswakami we-85% (iqondo lobushushu (iqondo lobushushu kufuneka lilinganiswe kufutshane ne-subtal). Ulwakhiwo lwalunqatshelwe ngokungqongqo kwinkungu, imvula, ikhephu, kunye nemozulu yomoya.
Phambi kwe-preer yeprinta kunye nepeyinti ephakathi, kwaye womisa imveliso emva kweeyure ezingama-24. Inkqubo yokutshiza isetyenziselwa ukutshiza izihlandlo ezi-1-2 ukufezekisa ububanzi befilimu echaziweyo, kunye nobunzima obucetyiswayo bungama-60 μm. Emva kokwakha, ifilimu yepeyinti kufuneka ithole kwaye ifihlakele, kwaye umbala kufuneka uguqulwe, kwaye akufuneki ukuba kungabikho sigcungc, i-orenji ye-orenji kunye nezinye izifo ze-orenji kunye nezinye izifo ze-orenji kunye nezinye izifo ze-orenji kunye nezinye izifo ze-orenji kunye nezinye izifo ze-orenji kunye nezinye izifo ze-orenji.
* Iiparamitha zokwakha:
Ixesha lokunyanga: imizuzu engama-30 (i-23 ° C)
Ubomi bonke:
| Ubushushu, ℃ | 5 | 10 | 20 | 30 |
| Ixesha lokuphila (h) | 10 | 8 | 6 | 6 |
I-Dossic Dossic (umlinganiso wobunzima):
| Ukutshiza okungenamoya | Ukutshiza umoya | Ibrashi okanye i-roll |
| 0-5% | I-5-15% | 0-5% |
Ukufumana ixesha (ubukhulu befilimu nganye eyomileyo):
| Iqondo lobushushu, ℃ | 10 | 20 | 30 |
| Ixesha elifutshane, h | 24 | 16 | 10 |
| Ixesha elide, usuku | 7 | 3 | 3 |
* Indlela yokwakha:
Ukutshiza: Ukutshiza komoya okanye umoya wokutshiza. Kuyacetyiswa ukuba isebenzise uxinzelelo oluphezulu lwerhasi.
Ibrashi / iRooll Coom: kufuneka ifezekise ububanzi befilimu echaziweyo.
* Amanyathelo okhuseleko:
Nceda unikezele kuzo zonke iimpawu zokhuseleko ekupakisheni ngexesha lokuhamba, ukugcinwa nokusetyenziswa. Thatha amanyathelo okhuseleko afanelekileyo kunye nokukhusela, uthintelo lomlilo, ukhuselo lokuqhuma kunye nokukhusela isisingqongileyo. Kunqande ukuphefumla kweempuths zeSolvent, kuphephe ukunxibelelana nolusu kunye namehlo ngepeyinti. Sukuginya le mveliso. Kwimeko yengozi, funa unyango kwangoko. Ukulahla inkunkuma kufuneka kungqinelane nemigaqo yoKhuseleko lukazwelonke noorhulumente basekhaya.
* Iphakheji:
Ipeyinti: 20kg / ibhakethi;
Unyanga iarhente / i-hardener: 4kg / ibhakethi
Ipeyinti: Ukunyanga iarhente / i-hardener = 5: 1 (umlinganiso wobunzima)
