Pombi yeSimbi Yakagadzirwa nePolyurethane
Mapaipi esimbi akagadzirwa nepolyurethane ipaipi inodzivirira kupfekwa zvakanyanya, iyo inoshandiswa zvakanyanya mumapaipi ekugadzirisa zvicherwa uye mapaipi ekutumira matope. Nzvimbo yemagetsi yemafuta-zvisaririra inoshandisa mapaipi aya kubvisa marasha nemadota, pamwe chete nemaindasitiri emafuta, makemikari, simende nezviyo.
Zvinhu zvirimo
1. Inodzivirira kupfeka
2. Dzivisa Kukura
3.Kuramba Kuora
4. Kuramba kukwegura kwehydrolysis
5. Kunyungudika Kwakakwirira
6. Kuramba Kushomeka Kwemuchina
7. Kuzvizora mafuta ega
Arex inosarudza premium master batch ine nzira yakagadziriswa nano kuti isimbise mashandiro epolyurethane. Inoita kuti zvigadzirwa zvepolyurethane zvakashongedzwa nemakemikari zvakagadzikana uye inoratidza kugona kwayo kuchinjika mumamiriro ezvinhu ari kushanda.
Pombi yesimbi yakagadzirwa nepolyurethane, seimwe yemapaunzi emuno ezvigadzirwa zvemigodhi muArex, inozivikanwa uye inoshandiswa nevatengi vedu vemigodhi.
Kuenzanisa kwehunhu huripo pakati pe common polyurethane ne nano-modified polyurethane
