Note: Afai e te manaʻo e aʻoaʻo atili e uiga i nisi auiliiliga malamalama o palasitika: faʻavae malamalama o palasitika-palasitika mata mea

O le palasitika o se mea e masani ona tatou faʻaaogaina i o tatou olaga i aso uma. E laʻititi lava e pei o taga palasitika, fagu pepe, fagu inu, pusa 'aiga o le aoauli, afifi palasitika, pei o le tele o ata faʻatoʻaga, meaafale, masini eletise, 3D lolomiga, e oʻo lava i roketi ma taʻavale fana, o loʻo iai uma palasitika.

O le palasitika o se lala taua o mea masani polymer mea, ma le tele o ituaiga, tele fua ma lautele faʻaoga. Mo le tele o ituaiga uga, e mafai ona faʻavasegaina faʻapea:

1. E tusa ai ma le amioga pe a vevela, e mafai ona vaevaeina palasitika i thermoplastics ma thermosetting faasaienisi tusa ai ma a latou amioga pe a vevela;

2. E tusa ai ma le ituaiga o tali atu i le taimi o le tuʻufaʻatasia o le resin i totonu o le palasitika, e mafai ona vaevaeina le resin i polymerized palasitika ma polycondensastik faʻasologa;

3. E tusa ai ma le faʻatonuga tulaga o le resin macromolecules, e mafai ona vaevaeina palasitika i ni ituaiga se lua: amorphous plastik ma crystalline uga;

4. E tusa ma le lautele o le faʻatinoga ma le faʻaaogaina, palasitika mafai ona vaevaeina i lautele lautele, inisinia palasitika, ma faʻapitoa palasitika.

Faʻatasi ai ma i latou, lautele-faʻamoemoe uga o le sili ona lautele faʻaaogaina i o tatou olaga i aso uma. Lautele-mafuaʻaga palasitika faʻasino i palasitika ma tele gaosiga tusi, lautele sapalai, tau maualalo ma talafeagai mo tele-fua talosaga. Lautele-mafuaʻaga palasitika i ai lelei gaioiga gaioiga, ma mafai ona suia i ni oloa mo faʻamoemoega eseese e ala eseese. Lautele-mafuaʻaga palasitika aofia polyethylene (PE), polypropylene (PP), polyvinyl chloride (PVC), polystyrene (PS), acrylonitrile / butadiene / styrene (ABS).

Lenei taimi o le a ou masani talanoa e uiga i le autu meatotino ma faʻaaogaina o polyethylene (PE). Polyethylene (PE) e sili ona lelei gaioiga ma faʻaaogaina meatotino, o le sili ona lautele faʻaaogaina ituaiga i gaosia resins, ma o lona gaosiga gafatia ua leva tulaga muamua i totonu o uma ituaiga palasitika. O le Polyethylene resins e tele lava ina aofia ai le maualalo o le polyethylene (LDPE), laina maualalo-density polyethylene (LLDPE), ma le maualuga-density polyethylene (HDPE).

Polyethylene e lautele faʻaaogaina i atunuʻu eseʻese, ma o le tifaga o lona sili ona faʻaaogaina. E faʻaumatia e tusa ma le 77% o le maualalo o le polyethylene ma le 18% o le maualuga-density polyethylene. I se faʻaopopoga, tui suia oloa, uaea ma uaea, papaʻu oloa, ma isi uma nofoia latou faʻaaogaina faʻatulagaina tele faʻatatau. Faʻatasi ai ma resins e lima lautele, o le faʻaaogaina o le PE e tulaga muamua. Polyethylene mafai ona feula suia e faia fagu eseese, apa, alamanuia tane, paelo ma isi koneteina; tui suia ina ia faia ai 'ulo eseese, paelo, ato, ato, ato ma isi pusa o aso taʻitasi, sundries i aso uma ma meaafale, ma isi. puna extrusion Gaosia ituaiga uma o paipa, fusi, alava, monofilament, ma isi I se faʻaopopoga, e mafai foi ona faʻaaogaina e gaosia ai uaea ma uaea ufiufi mea ma pepa gaosia. Faʻatasi ai ma le tele o talosaga, o vaega taua e lua o le polyethylene o paipa ma ata. Faatasi ai ma le atinae o taulaga fausiaina, mea taufaatoaga ata tifaga ma eseese taumafa, lavalava ma alamanuia afifiina alamanuia, o le atinae o nei lua fanua ua avea sili atu ma sili lautele lautele.
