Ka whakamahia e te hua te polypropylene hei kapia matrix, me te taapiri i etahi atu polyolefin resin, antioxidants me nga awhina tukatuka me etahi atu mo te whakaranu me te whakarereke. Kei te whakamahia hei 35kV me raro i te extruded he mea whakahiato taura hiko, he pai rawa nga ahuatanga dielectric, nga taonga miihini, nga waahanga teitei me te iti o te pāmahana me te pai o te mahi tukatuka. He rauemi whakamatao taura thermoplastic taiao.
Taonga:
Ko nga uara angamaheni o te ripanga ka ahu mai i te purongo whakamatautau momo i tukuna e te National Cable Testing Center.
Tukatuka:
1. Ka taea te whakamahi i roto i te hanga tikanga o te 35kV me raro te taura hiko CCV catenary production line taputapu extrusion, kahore he take mo te crosslinking me te degassing. Me tutuki te extruder ki te mana pāmahana teitei kaua e iti iho i te 250 ℃, ki te whakatutuki i te hangahanga polypropylene extrusion.
Te tautuhinga pāmahana tangohanga
E taunaki ana kia whakamahia he taitapa e toru-papanga (40-80-40); I mua me muri i te whakaputanga, me horoi te extruder.
1. E taunaki ana ki te whakamahi i te miro kotahi equidistant varied deep screw extruder with a screw length-diameter ratio of 25:1 and a screw compression ratio of about 2 for production, with the use of specialing shielding products for polypropylene insulation.
Ko te pāmahana tukatuka extrusion e taunaki ana i raro nei:
-Ko runga ake te pāmahana hei tohutoro anake. E taunaki ana kia whakatika nga kaihoko kia rite ki te waa i te wa o te tangohanga, te pehanga rewa me te ahuatanga tuuturu i muri i te tangohanga taura.
Whakapaipai hua
600kgs, he makuku-kore, parepare ra. (Takai kaata kowakawaka, me te putea kiriata hiri ki roto)
Tuhipoka:
1. 1.I mua i te whakamahi, he mea tika ki te whakaū kei te mau tonu te kohinga hiri. Ko te hua kia kaua e noho ki te hau mo te wa roa.
2. 2. Ko te kawe, te whakapapa me te rokiroki me aukati i te ra, te ua me te rumaki wai, aha atu, me ma, kia maroke, kia whai hau te taiao rokiroki.
