Usoro mmepụta ihe nkiri BOPET: Nleba anya

Ihe nkiri BOPET, dị ka a maara dị ka polyethylene terephthalate biaxial, bụ ihe nkiri polyester mere site na ịgbatị polyethylene terephthalate (PET) n'akụkụ ya abụọ bụ isi iji mee ihe nkiri arụpụtara arụ ọrụ.

Ụlọ ọrụ British ICI mepụtara ya na 1950s.

Ọ nwere ọtụtụ uru dị elu ike tensile, kemịkalụ na nkwụsi ike akụkụ, nghọta, reflectivity, gas na ihe mgbochi ihe na-esi ísì ụtọ, na mkpuchi ọkụ.

Mgbe ọtụtụ afọ nke mmepe gasịrị, ngwaahịa a sitere na ihe nkiri mbụ na-ekpuchi ihe na-eme ka ọ bụrụ ihe nkiri capacitor dị ugbu a, ihe nkiri nkwakọ ngwaahịa, ihe nkiri mkpuchi foto, wdg.

Ọkpụrụkpụ ya nwere ike ịbụ site na 4.5um ruo 350 μm.

Usoro mmepụta ya etolitela site na mmepụta obere kettle batch ruo ọtụtụ ịgbatị na mgbatị bidirectional n'otu oge.

Ụdị ngwaahịa ya esitela na ihe nkiri dị larịị gaa na ihe nkiri agbakwunyere multilayer, ihe nkiri agbasiri ike, na ihe nkiri mkpuchi mkpuchi.

Ihe nkiri polyester aghọwo otu n'ime ụdị ihe nkiri na-eto ngwa ngwa na ahịa.

Dehui FIlm bụ otu n'ime ndị na-eweta ihe nkiri bopet na China. Ugbu a, anyị na-emepụtakarị ha site na usoro ịgbatị ụzọ abụọ ụzọ abụọ. Site na mgbasawanye nke ngwa ngwa ya, ihe ndị dị mma nke ihe nkiri polyester na-ebuwanye elu. Na-amanye anyị imeziwanye àgwà na ịbawanye mmepụta.

BOPET usoro mmepụta ihe nkiri

Ugbu a, ka anyị webata usoro mmepụta ihe nkiri bopet. Usoro izugbe bụ nke a:

PET resin ihicha → extrusion nkedo → ogologo ịgbatị akwa akwa → ntụgharị transverse → winding → slitting and packing → nhazi miri emi.

Mpempe akwụkwọ nkedo agbazere PET

Mgbe agbazechara ma gbazee resin PET a mịrị amị, wee gwakọta ya site na nzacha na ezigbo nzacha na igwekota static, a na-ebufe ya na isi igwe site na mgbapụta mita. Mgbe ahụ mma site quenching roller N'ime oké Mpekere maka ojiji.

Extrusion nke biaxial gbatịa

PET oké ihe nkiri Biaxial (ntụziaka) ịgbatị bụ ịgbatị ihe nkiri ahụ ma ọ bụ mpempe akwụkwọ ewepụtara na extruder n'otu ọnọdụ okpomọkụ. Na longitudinal na transverse ntụziaka ime ka molekul yinye.

Ihu kristal nke a ga-ekpebi na-adabere na ya, mgbe ahụ, a na-eme ọgwụgwọ ikpo ọkụ n'ihe gbasara ịgbatị.

Ihe nkiri na-agbatị biaxial, n'ihi nhazi nke akụkụ molecular, na-eme ka kristal dịkwuo mma.

Ya mere, ọ nwere ike na-abawanye ike tensile nke ukwuu, tensile na-agbanwe modul, ike mmetụta, ike ndọkasị, melite oyi na-eguzogide, nghọta, airtightness, Eletriki mkpuchi, na gloss.

Ọtụtụ n'ime ihe nkiri dị larịị na-anabata usoro ịgbatị biaxial ụdị ụgbọ elu.
