*Vedhiyo:

*Zvinhu Zvigadzirwa:

1. Ichi chigadzirwa anatural high-refractory inorganic materialsechinhu chikuru.Yakagadzirwa nepamusoro-tembiricha inodzivirira moto inodzivirira inodzivirira ine yakakwirira-inodzivirira moto-inodzivirira muganhu wemaawa matatu kana kupfuura nepolymer binder.
2, chigadzirwa inhengo mbiri-yega yekuomesa coating, iri nyore kugadzira, inogona kupfapfaidzwa, kuzorwa.
3. Kupfekedzwa kwechigadzirwa ichiomesa nekukurumidza.Mushure memazuva makumi maviri nemanomwe ekurapa, kupeta kwacho kwakaoma uye kusingaite kugogodza, uye kune kuzununguka kwakanaka uye kuramba kwemamiriro ekunze.
4. Ichi chigadzirwahaina benzene uye asbestos zvinhu.Iyo haisunungure zvinhu zvine chepfu uye zvinokuvadza kana yaiswa kune yakanyanya kupisa uye haina kukuvadza kumuviri wemunhu.Iyo yekupisa conductivity yakaderera, uye muganhu wekudzivirira moto wesimbi unopfuura maawa matatu.

*Chigadzirwa Chishandiso:

1. Pamberi pekuvakwa, pamusoro pekugadzirwa kwesimbi kunofanira kubviswa, kucheneswa uye kubviswa zvachose.Wobva waisa pendi inorwisa ngura sezvinodiwa, ukobvu hwependi inorwisa ngura inofanira kuva 0.1-0.15mm.Anti-ngura pendi inowanzo gadzirwa nered dan kana epoxy zinc-rich anti-rust pendi.Mushure mekupfeka pendi yekudzivirira ngura, inoshandiswa NH-II uye WH-II yekunze gobvu simbi chimiro chekuvhara moto.
2. Mushonga wakaoma wakaoma wependi yezvikamu zviviri uye binder yakakosha inosanganiswa nemvura pachiyero che1: 0.1-0.2: 0.8-1, uye ipapo yakasanganiswa zvakafanana, uye ipapo kuvakwa kunogona kuitwa.
3. Pamberi pekuvakwa, iyo primer ichaputirwa kana kusaswa pamusoro pe substrate kwe 1-2 nguva.Mushure mekuoma kwepamusoro, iyo inoputira moto inogona kuiswa.Kuvaka kunogona kupfapfaidzwa kana kuzora.Kwekutanga 1-3 nguva, ukobvu hwejasi hunofanira kunge huri 2-3mm, uye hupamhi hwehuputi hwega hwega hunogona kunge hunenge 5-6mm kusvikira hupamhi hunotsanangurwa hwasvika.Nguva pakati pekuvaka imwe neimwe ndeye 12-18 maawa.Kutenderera kwemhepo kunofanira kuchengetedzwa panzvimbo yekuvaka.Kumhanya kwemhepo hakusi kudarika 5m/s.Izvo hazvina kukodzera kuvakwa apo condensation inoitika pamusoro pechimiro chesimbi.
4. Nokuda kwekunze kana mumhepo inopisa gasi, chifukidzo chepamusoro chekudzivirira chekuvhara chinofanira kurapwa.Iyo yekudzivirira yekudzivirira inopihwa nekambani.Ukobvu hwekufukidzira hunenge 0.25mm.

*Kuvaka nzira:

Kupfapfaidza: kusapfapfaidza mhepo kana kupfapfaidza mweya.High pressure non gas spraying.
Brush / roll coating: inofanirwa kuwana yakatsanangurwa yakaoma firimu ukobvu.
