Me pēhea te hanga i ngā kapu pepa? Te tukanga hanga ahumahi taahiraa-i-te-taahiraa
kapu pepaKa hangaia ngā pepa mā te tukanga tino aunoa mā te pani i te pepa pepa kounga kai-kore ki te ārai PE tiaki, ka tapahia kia kore e hangai, ka whakamahia he mīhini hanga tere-rahi hei hiri i ngā hononga taha, te tāpiri i te raro, me te whakapiko i te awhi o runga.
He tino aunoa, he tino tika te tukanga hanga kapu pepa hou, ā, he tino tika te mahi. Mō ngā wheketere hanga kapu o te awa whakararo, ko te pakari o te hanganga, te mahi kore turuturu, me te tutuki i ngā whakaritenga haumaru kai o te kapu whakamutunga e whakawhirinaki katoa ana ki te kounga o te awa whakararo. Pepa Panipanipapa me ngā papa tapahi-mate.
Hei kaiwhakarato matua o te ao mō ngā rauemi mata mō ngā takai kai, ka whakamāramahia e Nanning Paperjoy Paper Industry Co., Ltd. te tukanga hanga katoa o tētahi kapu pepa hou—mai i te muka rakau mata ki te ipu haumaru i roto i tō ringaringa.
Wāhanga 1: Te Hangarau Rauemi Mata o te Upstream me te Tahuri Tika
Ko te tūāpapa o tētahi kapu pepa kounga teitei kei roto i ngā whakaritenga hangarau o ōna rauemi mata.
- Kōwhiringa Papa Pepa Turanga me te Whakarōpūtanga Reo (GSM)
Pepa Ahumahi Ka whakamahia e ngā kapu he penupenu rakau wahine kounga kai anakePepa KapuKāore i te ture te whakamahi i te penupenu hangarua kei roto ngā mea whakama rama kanapa. Ka āta whakarōpūtia te matotoru me te taumaha o te rauemi e ai ki te whakamahinga:
Ngā Kapu Inu Wera: Whakamahia he pepa pepa 150–320 gsm hei whakataurite i te whakamarumaru wera me te pakari pai o te pupuri ringa.
Ngā Kapu Inu Matao me te Inu Maeneene: Whakamahia he rauemi taumaha 280–350 gsm hei ārai i te hinga o te kapu i ngā taiao haumākū nui me te pāmahana iti.

Ka rewahia ngā pire PE kai-kai i te 200°C–350°C, ā, ka tukuna tika atu ki runga i te pepa, ka hanga he ārai moroiti (0.01–0.03mm te matotoru). E rua ngā huarahi matua mō tēnei:
Paninga PE taha-kotahi: He paninga anake ki roto. Koinei te whakatakotoranga nui rawa atu o te ao, he mea hanga motuhake mō ngā inu wera (tae atu ki te 90°C).
Paninga PE Taha-Rua: Kua pania ki ngā mata o roto, o waho hoki. He mea nui tēnei momo hanganga mō ngā inu matao; ka ārai te paparanga PE o waho i te mimiti o te hau (“werawera”) ki roto i te pepa, kia mārō ai te kapu, kia pakari ai hoki tōna hanganga.
