Product Detail

Iyo yakasviba phosphated hydraulic simbi chubhu inogadzirwa zvinoenderana neDIN 2391-C kana En10305-4.Black phosphated hydraulic simbi machubhu anogadzirwa neinotonhora inodhonzwa inopenya simbi pombi se substrate.Uye mukati nekunze madziro epombi ari phosphatized ne phosphating mhinduro kuti aite dema phosphating inodzivirira firimu.Bvisa mafuta anodzivirira ngura kuburikidza nemamicropores ari muphosphating firimu rekudzivirira ngura kurapwa, uye vhara magumo ese ekudzivirira guruva kurapwa.Hunhu hukuru hwe hydraulic dema phosphating simbi pombi iyunifomu ruvara, yakakwirira kuenderana, uye yakanaka rust kuramba.

Phosphated hydraulic simbi machubhu anoshandiswa zvakanyanya mu hydraulic masisitimu, michina yekuvaka uye mota dzekuvaka.
