PE e faasino ile polyethylene (Polyethylene), lea ose thermoplastic maua mai polymerization o ethylene monomers. O le polyethylene e iai uiga o le mautu lelei o vailaʻau, tetee a'a, fa'amavaega, fa'agaioiga faigofie ma fa'alili, ma sili atu le malosi maualalo-vevela. O se mea masani palasitika faʻaaogaina lautele i alamanuia ma olaga i aso uma.
E tusa ai ma metotia sauniuni eseese, polyethylene e mafai ona vaevaeina i polyethylene maualuga-density (HDPE), polyethylene maualalo maualalo (LDPE), laina laina maualalo polyethylene (LLDPE) ma isi ituaiga. Faatasi ai ma i latou, HDPE e maualuga le maaa, tete'e o le vevela ma le mamafa, ma e masani ona faʻaaogaina i le gaosiga o pusa palasitika malo, paipa vai, paipa alavai i lalo o le eleele, ma isi.; O le LDPE e iai le fetuutuuna'i lelei ma mea fa'amalosi, ma e masani ona faʻaaogaina i le gaosiga o ata faʻapipiʻi fetuutuunai , taga meaai, ata palasitika, ma isi.
PE o se mea palasitika taua e faʻaaogaina lautele i fanua eseese, pei o le afifiina, fausiaina, faaeletonika, ta'avale, faafomai, fa'ato'aga, ma isi. E le gata ina maualalo le tau ma lelei le faatinoga, ae o loʻo iai foʻi lelei le toe faʻaaogaina ma le puipuiga o le siosiomaga, ma o se mea palasitika sili ona lelei.
PVDF e faasino ile polyvinylidene fluoride (Polyvinylidene fluoride), lea o se resin thermoplastic maualuga-faatinoga maua e polymerization o vinylidene fluoride monomer. O le PVDF e maualuga le teteʻeina o vailaʻau, mautu maualuga vevela, lelei tele le fa'aogaina o le eletise, tete'e fa'avevela ultraviolet, e le mu-mu ma isi mea lelei, o lea e faʻaaogaina lautele i alamanuia kemisi, faaeletonika, aerospace, fausiaina, faafomai ma isi matata.
PVDF o loʻo i ai le faʻatinoga lelei o le gaioiga ma le faʻaogaina o le faʻatinoga, ma e mafai ona saunia i oloa o foliga eseese ma faʻamatalaga e ala i le extrusion, tui tui, kalena ma isi auala. O oloa PVDF e iai le tele o fa'aoga, pei o le:
Fa'ameamea: E mafai ona fa'aoga le PVDF e gaosia ai mea fa'a vaila'au e pei o tane teu, paipa, alavai, pamu, ma isi. O loʻo i ai mea sili ona lelei e pei o le corrosion resistance ma le maualuga o le vevela.
fanua faaeletonika: PVDF e mafai ona faʻaogaina e gaosia ai mea faʻaeletoroni e pei o uaea, diaphragms ma'a, ma sensors, ma o loʻo i ai uiga faʻamalo eletise lelei ma mautu vailaʻau.
fanua faufale: PVDF e mafai ona faʻaogaina e gaosia mea faufale e pei o le fausiaina o puipui puipui fafo, taualuga, ma mea e fa'amama ai le vevela, ma e lelei le tau tetee ma UV tetee.
Fa'afomai: PVDF e mafai ona faʻaaogaina e gaosia ai masini faʻafomaʻi e pei o paipa faʻafomaʻi ma totoga faʻapitoa, ma e iai le lelei o le biocompatibility lelei.
I se upu, O le PVDF o se mea polymer e sili ona lelei le faʻatinoga ma e lautele le faʻamoemoega faʻaoga.
PE MA PVDF
O le faʻaogaina o le PE ma le PVDF i le alumini pepa e masani lava o se mea faʻapipiʻi e faʻaleleia ai le susu, oxidation tetee ma corrosion tetee o alumini pepa. Aemaise lava:
PE ufiufi alumini pepa: PE fa'apipi'i alumini pepa o se puipui puipui e faia e ala i le ufiufi PE resini luga o le alumini pepa alumini e extrusion., ufiufi ma isi metotia. PE fa'apipi'i alumini pepa e lelei le susu, oxidation tetee ma corrosion tetee, ma e mafai ona fa'aogaina e gaosia ai ato fou e teu ai, taga afifi meaai, mea faufale faufale ma isi oloa.
PVDF ufiufi alumini pepa: PVDF faʻapipiʻiina alumini pepa o se puipui puipui na faia e ala i le ufiufi PVDF resin i luga o le pito i luga o le alumini pepa e ala i le vevela vevela ma isi metotia.. PVDF fa'apipi'i alumini pepa e malosi le tau, tetee corrosion kemikolo ma tetee maualuga vevela, ma e mafai ona faʻaaogaina e gaosia ai oloa maualuga e pei o le fausiaina o puipui puipui i fafo, mea taualuga, vaalele, ma taavale.
I fa'atinoga fa'atino, E mafai ona filifilia le pepa alumini faʻapipiʻi PE ma le PVDF faʻapipiʻi alumini e tusa ai ma manaʻoga faʻapitoa. I se tulaga lautele, o le tau o pepa alumini faʻapipiʻiina PE e matua maualalo lava, lea e talafeagai mo nisi oloa e maualalo manaoga, ae o le tau o le PVDF-coated alumini pepa e maualuga atu , talafeagai mo oloa maualuga mana'omia.
