Kedu ihe ihe nkiri overwrap polypropylene dabere na Biaxial?

Ihe nkiri polypropylene biaxial (BOPP) bụ ụdị ihe nkiri nkwakọ ngwaahịa na-agbanwe agbanwe. A na-agbatị ihe nkiri mkpuchi polypropylene dabere na biaxial n'ime igwe yana ntụgharị ntụgharị. Nke a na-ebute nghazi yinye molekụla n'akụkụ abụọ ahụ.

Ụdị ihe nkiri nkwakọ ngwaahịa na-agbanwe agbanwe na-emepụta site na usoro mmepụta tubular. A na-afụ ụfụ ihe nkiri nke yiri tube ma kpoo ọkụ ruo ebe ọ na-eme ka ọ dị nro (nke a dị iche na ebe mgbaze) ma jiri ígwè gbatịa ya. Ihe nkiri a na-agbatị n'etiti 300% - 400%.

N'aka nke ọzọ, a pụkwara ịgbatị ihe nkiri ahụ site na usoro a maara dị ka mmepụta ihe nkiri tent-frame. Site na usoro a, a na-ebupụ polymer n'ime mpịakọta nkedo jụrụ oyi (nke a makwaara dị ka mpempe akwụkwọ ntọala) wee dọpụta ya n'akụkụ igwe. Ime ihe nkiri Tenter-frame na-eji ọtụtụ mpịakọta mpịakọta mepụta ihe nkiri a.

Usoro tent-frame n'ozuzu na-agbatị ihe nkiri ahụ 4.5: 1 na ntụziaka igwe na 8.0: 1 na ntụgharị ntụgharị. Nke a na-ekwu, oke a na-agbanwe agbanwe.

Usoro tent-frame bụ ihe a na-ahụkarị karịa ụdị tubular. Ọ na-emepụta ihe nkiri na-egbuke egbuke nke ukwuu. Ntughari biaxial na-abawanye ike ma na-ebute isi ike dị elu, nghọta na-abawanye ụba, na nnukwu iguzogide mmanụ na griiz.

Ihe nkiri BOPP na-etu ọnụ na-abawanye ihe mgbochi na vepo na oxygen. Nguzogide mmetụta na nkwụghachi mgbagha dị mma nke ukwuu na ihe nkiri BOPP na polypropylene shrink.

A na-ejikarị ihe nkiri mkpuchi polypropylene dabere na biaxial maka nkwakọ nri. Ha na-edochi ngwa ngwa cellophane maka ngwa gụnyere nri nri na nkwakọ ụtaba. Nke a bụ isi n'ihi ihe onwunwe ha dị elu na ọnụ ala dị ala.

Ọtụtụ ụlọ ọrụ na-ahọrọ iji BOPP n'ọnọdụ ihe nkiri ndakpọ ọdịnala ka ha na-egosipụta njirimara na ikike ndị dị elu karịa nke ihe nkiri nkwakọ ngwaahịa na-agbanwe agbanwe.

Ekwesiri iburu n'uche na ikpochapu okpomọkụ siri ike maka ihe nkiri BOPP. Otú ọ dị, nke a nwere ike ime ka ọ dịkwuo mfe site na ikpuchi ihe nkiri ahụ mgbe a na-edozi ihe na-ekpo ọkụ na-ekpo ọkụ ma ọ bụ na-ejikọta ya na co-polymer tupu nhazi. Nke a ga-eme ka ihe nkiri multi-layer pụta.
