Fa'aaogāga
O koneteina, pesini, ma fata e fausia mai pepa polystyrene ua fa'aosoina e fa'aaogaina mo le afifiina o le tele o ituaiga mea'ai. O le ata polystyrene e fa'atulagaina fa'alua e fa'avevela i totonu o afifi blister, fata aano o manu, tapuni koneteina, ma kuki, lole, mea'ai suamalie, ma isi afifi mea'ai pe a mana'omia le manino.
O meaafale o se isi vaega tele o le faʻaaogaina o polystyrenes. O ufi faitotoʻa o pusaaisa ma paneli o meaafale o ni faʻaoga masani ia o le polystyrene i le thermoformed impact. O faʻataʻitaʻiga extruded o le polystyrene mafiafia poʻo le foamed impact e faʻaaogaina mo faʻata poʻo faʻavaa ata, ma faʻalava mo galuega faufale.
O le polystyrene fa'aoga lautele e fa'a'ese'ese pe manino pe fa'ailogaina mo vaeluaga o potu, faitoto'a o faleta'ele, tioata, ma fa'aoga mo moli. O le fa'a'ofuofuina o le polystyrene e fa'aaogaina mo mea tau fale, e pei o ulo fugāla'au, oloa tau tausiga o le tagata lava ia, ma meataalo. O le polystyrene fa'aoga lautele e fa'aaogaina mo naifi, fagu, selu, ipu e lafoa'i, ipu, ma fata. E mafai ona fa'aaogaina le fa'a'ofuofuina o le polystyrene e liua ai i fagu, fagu, ma isi ituaiga koneteina tatala.
O le polystyrene fa'aleagaina fa'atasi ai ma mea fa'aopoopo e tete'e atu i le afi e fa'aaogaina mo pusa o masini, e pei o mea mo televise ma masini laiti. O le polystyrene fa'aleagaina fa'atulagaina ua fa'afouina i mea fa'aopoopo e tete'e atu i le afi e fa'aaogaina mo pusa o masini pisinisi ma meaafale ona o lona matagofie ma le faigofie ona fa'agasolo. O mea fa'aeletoronika fa'atau, e pei o kaseti, uili, ma pusa, o se vaega vave ona tuputupu a'e mo le fa'aaogaina o polystyrenes. O fa'aoga fa'afoma'i e aofia ai mea e aoina ai fa'ata'ita'iga, ipu petri, ma paipa fa'ata'ita'i. I se taumafaiga e fa'aleleia atili ai le fa'aogaina o le malosi o fale ma isi fale, o le fa'aaogaina o polystyrenes i le laupapa foam extruded fa'atasi ai ma mea fa'aopoopo e tete'e atu i le afi mo puipui ma lalo o papa ua i ai le tuputupu a'e tele i tausaga talu ai nei. A fa'aaogaina o se mea e ufiufi ai, o le laupapa foam extruded e tausisia mana'oga o tulafono tetele o fale fa'apea fo'i ma fa'atonuga a le feterale ma le militeri.
E fa'aaogaina le polystyrene latex microspheres i le flow cytometry, fluorescence microscopy, ma o ni calibration particles. E maua lona fa'aaogaina i le iloa o ni nai antigens po'o antibodies i le serum, mimi, ma cerebro-spinal fluids. E fa'aaogaina fo'i o se stimulus responsive particulate emulsifier mo le oil-in-water emulsion.
Ata tifaga e afifi ai; vaega ua mamanuina mo taavale, masini eletise, meaafale, ma isi mea faapena; ufi uaea ma uaea; tapuni o pusa meaai; oloa ua vali ma faapipii; fagu; mutia ma mutia fa'apitoa; paipa palasitika; lavalava e ofuina (ua valiina i le 'aisa); upega i'a; mea e fa'apipi'i ai taotoga; fusi; pepa fa'apitoa; palasitika fa'amalosia; faamama e le'i lalagaina ma lafoa'i.
Afifiina：
25KG/Ato
Tausia ma teuina
Umi e teu ai: 24 masina mai le aso na gaosia ai i totonu o le afifiina muamua e leʻi tatalaina teuina i se nofoaga malūlū ma mago, ʻaloʻese mai le la saʻo, vai.
Ia tapuni lelei le fagu ma teu i se nofoaga mago ma lelei le ea. Vevela fautuaina mo le teuina 2-8°C
