Low density Polyethylene resini
Low-density polyethylene (LDPE) o se resini gaosia e fa'aogaina ai le fa'agasologa o le mamafa e ala i le polymerization free radical o le ethylene ma o lea e ta'ua ai fo'i o le "high-pressure polyethylene".Talu ai ona o lona filifili mole e tele lala uumi ma pupuu, o le LDPE e itiiti ifo le tioata nai lo le polyethylene maualuga (HDPE) ma o lona mamafa e maualalo.O lo'o fa'aalia ai le mama, fetu'utu'una'i, lelei le fa'a'aisa ma le a'afiaga.LDPE e mautu fa'a kemikolo.E lelei le tete'e atu i acids (vagana ai le malosi oxidizing acids), alkali, masima, mea e sili ona lelei insulation eletise.E maualalo lona sao i totonu.LDPE e maualuga le suavai ma lelei le fa'agaioiina.E talafeagai mo le faʻaaogaina i ituaiga uma o faʻagasologa o le thermoplastic, e pei o le tui tui, faʻapipiʻiina, faʻafefeteina, rotomolding, faʻapipiʻiina, faʻafefe, thermoforming, vevela-jet uelo ma le faʻafefe.
Fa'atatauga
O le LDPE e fa'aaogaina mo le faia o ata.E masani ona faʻaaogaina i le gaosiga o ata faʻatoʻaga (mulching film and sheshed film), afifiina ata (mo le faʻaaogaina i le teuina o lole, fualaau faisua ma meaʻai aisa), ata faʻafefe mo le afifiina o vai (mo le faʻaogaina i le afifiina o susu, soya, sua, pa'u pi ma susu soya), ato fa'apipi'i mamafa, ata fa'aitiitiga fa'apipi'i, ata fa'alava, ata fa'apipi'i, ata fa'aoga fau fale, ata fa'apipi'i fale gaosi oloa ma taga mea'ai.
LDPE o lo'o fa'aaogaina lautele i le gaosiga o le uaea & uaea fa'a'ese'ese fa'alava.LDPE feso'ota'i fa'asagatau o le mea autu lea e fa'aaogaina i le fa'a'ese'esega o uaea maualuga-voltage.
O loʻo faʻaaogaina foi le LDPE i le gaosiga o mea faʻapipiʻi tui (e pei o fugalaʻau faʻapitoa, mea faʻafomaʻi, vailaʻau ma mea e teu ai meaʻai) ma faʻapipiʻi faʻapipiʻi, ipu, uaea & uaea faʻapipiʻi ma oloa faʻapipiʻiina.
O lo'o fa'aogaina fo'i le LDPE mo le faia o mea 'o'o'o fa'afefeteina e pei o koneteina mo le teuina o mea'ai, vaila'au, mea teuteu ma vaila'au, ma tane.
Paketi, Teuina ma Felauaiga
O le resini o lo'o fa'apipi'iina i totonu o taga lalaga polypropylene e fa'apipi'iina ata.Ole mamafa ole 25Kg/pe.O le resini e tatau ona teuina i totonu o se fale teu oloa matutu ma mamao ese mai le afi ma le susulu o le la.E le tatau ona faaputuputu i luga o le ea.I le taimi o felauaiga, e le tatau ona faʻaalia le oloa ile susulu malosi o le la poʻo le timu ma e le tatau ona feaveaʻi faʻatasi ma le oneone, palapala, uamea, koale poʻo tioata.O felauaiga faʻatasi ma mea oona, pala ma mu e matua faʻasaina.
