penapena Heat, ka whakamahi i enei hua ko te 20%. Korere kore e waikura, e kore e hanga e roto o putunga calcareous me tohu taiepa ā ano maitai maheni, e faaore te waku me te ātete, ko te kupu rere noa te wai i roto i te putorino. e kore e ratou i te pēne o te hiko. Haunga whakawera i korere polypropylene ahei o pato te tohu record pāmahana o 95 ° C.

He ngāwari ki te kawe me te tāuta Products, rite he nui mama atu i maitai ratou. Ngāwari tapahia ki te kutikuti motuhake. Tāutanga o putorino polypropylene o te pūnaha whakawera e he wa iti. Hoki te hononga i waenganui i te putorino, me te whare titau te taputapu whakapiringa motuhake. I roto i tenei take, nga pito o te hua i waho te hiahia mo te horoi.

whakapuru

A, no te ekeeke te hua, e kore e maka atu a ratou distortions ranei piko rite polypropylene - ko te rauemi pakeke, e te tikanga e me mahi nga hohoko katoa me ētahi atu mahi i te tikanga o whare polypropylene. mahi Tāuta te pai mahue ki ngaio, te kore i reira ko te mōrea o te whiwhi pūnaha whakawera rawakore-kounga. Ki te tika, ka taea e te putorino polypropylene kia paku piko, te para i te reira ki te wāhi e hiahiatia ana te whakamahi i te whare dryer. Heoi, i roto i te take o te pēhanga kaha i runga i te hua rauemi kia waha deformation whati i te taua ranei.

Tēnei wā hua roa ngongo o 4 mita. hua Hangaia o toru ngā momo, ia o nei te hangaia mo te tono ngā (PN10, PN20, PN25). eke te pūnaha whakawera i roto i ngongo kirihou rerehu, te tikanga hanga o PN25. āhuatanga Ētahi atu tenei ahua i roto i taua te whakapakaritia ai i te roto ki te konumohe takai konumohe, reira, e kore e kirihou. Nā ki te ngongo whakaū o te toru o nga rōpū kia te whakamahi i te pēhanga o runga ki te 8 atmospheres me pāmahana ki runga ki te 70 ° C, ai te wā - 50 tau. Otiia ki te mea ka whakanui i te pēhanga wai me te pāmahana āhuatanga ora ngongo ka e iti.

mutunga

Ka taea e koe te hoko paipa polypropylene mō te whakawera i roto i tetahi toa pūmārō. Ko ngā iti te utu, i hanga e wātea ana ratou. tei te utu i runga i te diameter (25 ki te 125 mm), me te pae i pā ana ki 40 ki te 1500 atu ia moni mita tapawha ranei. Te nuinga i kite kē i roto i te kounga teitei o te rauemi me te utu manapori.
