Ko te hua he rauemi whakamarumaru polyethylene kua whakarereketia, kua tohua te kapia polyethylene kounga teitei. Ka aro te tukanga ki te taapiri i nga taonga awhina me te riterite o te whakaranu, me te whakarite kia ma, kia kore he parahanga. Ka whakamahia te hua mo te 10kV te hono i te papanga whakamaarama taura polyethylene, me te tohu tinana me te matū pono, me te pai o te mahi tukatuka.

Ko nga uara angamaheni o te ripanga ka inehia i raro i te tikanga ka tino hono te rauemi, a, ki te kore e tutuki te hononga whakawhiti, ka rereke pea te mahinga o te rauemi.
Tukatuka:
e tūtohu ana ki te whakamahi i te extruder tikanga (toru-papahanga tahi-extrusion, roa-diameter ōwehenga o 20:1 ki te 30:1) mo te mahi, me te tahi atu taputapu e hiahia ana ki te whakarite kia rite ki te āhuatanga.

Kei runga ake te pāmahana hei tohutoro anake. E taunaki ana kia whakatika nga kaihoko kia rite ki nga ahuatanga o te waa i te wa o te tangohanga, te pehanga whakarewa me te ahuatanga tuuturu i muri i te tangohanga taura. Ko tenei tono tukanga ehara i te mea mo te mahi tahi i waenga i nga taha.
Whakapaipai hua:
Kua hirihia nga kaata me te kapi, me nga palleti kei raro o te pouaka, kua kapi ki te whakamarumaru kiriata polyethyleneKo te taumaha kupenga o ia kaata he 600 kg.
