Ingxowa yeplastiki ebomini bethu

I impahla bekusoloko kukho inxalenye ebalulekileyo yenkqubo imveliso nayiphi na inkampani self-nokuhlonipha. Ukuveliswa kwinkulungwane - izinto zeplastiki - lula kakhulu umsebenzi abenzi nabathengisi.

Ndandifeketha na, iyahlala, ukumelana ukunyakama, ixabiso eliphantsi kakhulu - a ngokwezalathi ezibalulekileyo kakhulu impahla. Ingxowa yeplastiki ukuze ngokukhawuleza zigxile ebomini bethu ukuba sicinga ukuba andisakwazi ukwenza ngaphandle.

prehistory

iingxowa ivale kuqala ngo-1957 eUnited States. Basebenzisa ukuze ukupakisha kwiisendwitshi. kweminyaka elishumi kamva, sele-30% yeemveliso yokubhaka US zipakishwe kupakisho ezinjalo. Emva koko, kunye neNtshona yeYurophu wayeyithanda le phakheji, kangangokuba ngo-1973 imveliso iiphakheji lafikelela million 11.5. Ngowe-2002, xa ihlabathi lonke ingene ukukhula polyethylene ukupakisha, ngumthamo opheleleyo global ezi mveliso ngu 4-5 ezigidi ngonyaka ngamnye. Iinkokheli mveliso iiphakheji zintle ebezithunyelwe (4.5-5 m) - China, eRashiya, South-East Asia. Nesingxobo seplastikhi obhityileyo senziwe polyethylene ashinyeneyo (uxinzelelo ephantsi) HD (njalo-ebizwa ngokuba 'lenzwinini "). Wambi kusetyenziswa polyethylene ukunyuka koxinzelelo, kodwa ingxinano ephantsi (LD, LLD), ngoko iipakethi kubonakala kakuhle. Noko ke, ingxowa sopakisho enjalo ezingcakacileyo na amandla aphezulu.

Ezahlukeneyo, kwaye ke umdla

Isingxobo seplastiki ezibonwayo usoloko etsala ingqalelo kuphela abantwana kodwa abadala. Oku kunegalelo appliqués liqaqambileyo nesibeke zonke iintlobo izihloko. umfanekiso-abane isicelo iphakheji, usebenzisa indlela yokushicilela flexographic, unako zisebenza njengeendlela ezisebenzayo noko self-promotion. Iveliswe iintlobo ezahlukeneyo iimveliso ngokuxhomekeke khona: iingxowa Ukupakisha (ecacileyo); Bag-shirt; isikhwama ndzhendzheleko yokubamba, prorubnoy; iingxowa inkunkuma (kunye iidayi) lohlobo "t-shirts", okanye iirholithi okubambezelayo; Izingxobo uphawu (a uphawu). Makhe zihlale phezu iipasela lohlobo "T-shirt". Olu hlobo imveliso soyisiwe lesiteketiso izibambo ahlabayo ekuso. Ukuveliswa upakisho "Mike" yinto yomhla nyaka 1982. Ukuba zenziwa emva kwe nezinye iimveliso kolu didi, kodwa sekunjalo ngokuqinileyo kuyo isigxina inkokeli, ingakumbi kuthungelwano kwamashishini zorhwebo. A umahluko kwakhona iiphakheji pnd- kunye LDPE. Ukuveliswa iipakethi iHDPE esekelwe granules polyethylene xi ophezulu, ngokulandelelana, IPA - ingcinezelo eliphantsi. iiphakheji LDPE - oku ke impahla, apho sisebenzisa kubomi bemihla ngemihla (for amancinci naphakathi-fill). Kwaye IPA-iipakethi zisingathwa nosebenzisa upakisha enkulu (20-30 kg) kwaye inokuba nomahluko ukanti ukumelana neengxaki ezigqithisileyo kunye neempembelelo engentle yokusingqongileyo. Ngoko ke, libya-polyethylene ephezulu isetyenziselwa ukwenziwa kwemibhobho uxinzelelo nokulinganiswa, cable sheathing.

ingozi

Asingekhe silibale ngayo umonakalo owabangelwa kwisingxobo seplastikhi eziphilayo. Ngenxa yokuba ukusetyenziswa Ozidelayo iimveliso zeplastiki Umhlaba, ngathi, phantse esaphuma ngalo, aze ophilileyo ihlabathi liphela kwi planethi uvakalelwa kwiziphumo ezibi oku (ngakumbi, eziphila elwandle ngokuthabatha iplastiki ukutya). Asimele silibale ukuba impahla nganye ngekhilogram lubamba kwinkqubo yokuvelisa 1.2 kg njengesibonelelo elixabisekileyo - i-oli ekrwada. Worth ukukhumbula ukuba yeplastiki anokuphinda asetyenziswe: evela kwiingxowa zeplastiki inkunkuma zenziwe amacandelo iingcingo, iingcingo, izitulo ipaki kunye nangaphezulu. Kunokuba zinokutshisa umbane. Simele sikhumbule ukuba polyethylene kunokuba ezahlukeneyo - nkqu ngaphantsi ityhefu emanzini.
