Paipa Raina Polyurethane
Ko te putorino rino polyurethane he paipa paipa whakakakahu nui, e whakamahia nuitia ana i roto i nga pipeline tukatuka kohuke me nga pipeline tuku hiku.Ka whakamahia e te teihana hiko hiko parakapoka te paipa mo nga punaha tango waro me te pungarehu, tae atu ki nga umanga hinu, matū, raima me te witi.
Ngā āhuatanga
1. Ka mau-atete
2.Prevent Tauine
3.Corrosion Ātete
4. Ātete ki te hoholo o te hydrolysis
5. Elasticity Teitei
6. Te Atete ki te Whakaoho Miihini
7. Whakahinuhinu whaiaro
Ka kowhiria e Arex te roopu rangatira moni me te huarahi kua whakarereke-nano ki te whakapakari i te mahi o te papanga polyurethane.Ka hangaia e ia nga hua o te polyurethane me te hanganga matū pumau me te whakaatu i tana urutau i roto i nga ahuatanga mahi.
Ko te putorino rino polyurethane, ko tetahi o nga patent a-whare o nga hua maina i Arex, he rongonui, e whakamahia ana e o taatau kaihoko maina.
