He pēke kirihou i roto i to tatou oraraa

Kua kua tonu te rauemi tākai he wahi nui o te tukanga whakaputa o tetahi kamupene whaiaro-mo. Ko te tenenga o te rau tau - rauemi kirihou - nui ngä te mahi o ngā kaiwhakanao me kaihokohoko.

Otinga, mauroa, makuku resistance, utu āhua iti - he tohu tino nui o te rauemi tākainga. He pēke kirihou kia hohoro a pūmau i roto i to tatou oraraa e whakaaro tatou e nehenehe e kore te mahi e matou, kahore reira.

prehistory

peke tarapēke Tuatahi whakaputaina i roto i 1957 i roto i te United States. whakamahia ratou i te reira ki te fao hanewiti. Kotahi tekau nga tau i muri mai, kua 30% o te hua parāoa US Kikī i roto i taua pōkai. Na, ko Western Europe i mīharo e tenei mōkihi, me te hua e i roto i 1973 tae te hanga o mōkī 11.5 miriona waeine. I roto i te tau 2002, ka taupokina te ao katoa i tōnuitanga polyethylene tākai, te rōrahi ao katoa o enei hua ko 4-5 trillion ia tau. Feia faatere o hokohoko te mōkī pai tarapēke (4.5-5 m) - China, Russia, Tonga-Te Tai Rāwhiti Asia. hanga te pēke kirihou angiangi te o te polyethylene mātotoru (pēhanga iti) HD (pera-ka karanga "haruru"). Kei te te tahi mau taime whakamahia polyethylene pēhanga teitei, engari kiato iti (LD, LLD), ka puta maheni pākete. Otiia, he taua putea tākai angiangi he kaha nui.

Rerekē, me reira ngā

pēke kirihou ataata rata tonu te aro o kahore anake tamariki, engari ano hoki ngā pakeke. whai wāhi ana tēnei ki te appliqués kanapa runga katoa o ngā kaupapa. E wha-image tono ki te mōkihi, mā te whakamahi i te tikanga o te tā flexographic, ka taea e te mahi rite te tikanga āhua whai hua o te whakatairanga-whaiaro. Hua ngā momo rerekē o ngā hua i runga i to ratou ūnga rānei: tarapēke peke (mārama); Bag-shirt; putea ki te koropiko kakau, prorubnoy; peke paru (ki tae) o te momo "t-hāte", pehi pokohiwi ranei; peke parani (he waitohu).

He pnd- me LDPE pōkai hoki te puta ke. Production o pākete HDPE i runga i nga granules polyethylene o te pēhanga teitei, aua, IPA - pēhanga iti. pōkai LDPE - ko te rauemi tākai, e whakamahi tatou i roto i te ora ia rā (mo te iti me te reo makona-) tenei. Na e te āhuatanga IPA-pākete i roto i taua whakamahia mō te tākai nui (20-30 kg) me kia rerekē, me te ātete ano ki taumahatanga nui me ngā awenga taiao kino. Na reira, iti-kiato polyethylene te whakamahia mo te hanga o putorino pēhanga me whare, taura sheathing.
