Vaega ma ituaiga o polymer thermoplastic

O le polymer thermoplastic o se ituaiga o polymer e faʻaalia i lona mafai ona faʻafefeteina ona faʻamaua ai r.epee aunoa ma se suiga taua i ana mea kemisi po'o uiga fa'atinoga. Thermoplastic polymers o loʻo faʻaaogaina lautele i le tele o talosaga, e aofia ai le afifiina, vaega taʻavale, vaega eletise, ma masini faʻafomaʻi, ma isi.

Thermoplastic polymers e iloga mai isi ituaiga o polymers, e pei o polymers thermosetting ma elastomers, e ala i lo latou gafatia e faʻafefeteina ma toe faʻaleleia i le tele o taimi. E mafua lenei mea ona o le mea moni o polymers thermoplastic o loʻo faia i filifili uumi o molelaʻau o loʻo faʻapipiʻi faʻatasi e le vaivai o malosiaga intermolecular. Pe a faʻaogaina le vevela i se polymer thermoplastic, o nei malosiaga intermolecular e faʻavaivaia, faʻatagaina filifili e sili atu le saʻolotoga ma faʻaleleia atili le mea.

O se tasi o faʻamanuiaga autu o polymers thermoplastic o lo latou faʻaogaina. E mafai ona fa'atulagaina e maua ai le tele o mea fa'aletino ma masini, e aofia ai le fetu'una'i, malosi, malosi, ma le tete'e atu i le vevela, vaila'au, ma le fa'avevela UV. O le mea lea e talafeagai ai mo le tele o talosaga e manaʻomia ai uiga faʻatinoga faʻapitoa.

O le isi mea lelei o polymers thermoplastic o lo latou faigofie o le gaioiga. Talu ai e mafai ona faʻafefeteina ma toe faʻaleleia i le tele o taimi, e mafai ona faigofie ona faʻapipiʻiina i foliga faigata e faʻaaoga ai auala eseese, e pei o le tui tui, extrusion, blow molding, ma le thermoforming. O le mea lea e avea ai i latou ma filifiliga taugofie mo le tele o gaosiga o vaega ma vaega.

E tele ituaiga eseese o polymers thermoplastic, e tofu ma ana lava seti tulaga ese o meatotino ma faʻaoga. O nisi o ituaiga sili ona taatele e aofia ai:

1. Polyethylene (PE): O se polymer thermoplastic fa'aoga lautele lea e lauiloa mo lona tau maualalo, fetuutuunai, ma le tetee atu i aafiaga ma vailaʻau. E faʻaaogaina i le tele o faʻaoga, e aofia ai le afifiina, paipa, ma le faʻaogaina o uaea.
2. Polypropylene (PP): O le isi polymer thermoplastic e masani ona faʻaaogaina e lauiloa i lona malo, malosi, ma le tetee i le vevela ma vailaʻau. E faʻaaogaina i le tele o talosaga, e aofia ai vaega taʻavale, afifiina, ma masini faʻafomaʻi.
3. Polyvinyl chloride (PVC): O se polymer thermoplastic lea e lauiloa mo lona gafatia, tumau, ma le tetee atu i afi ma vailaʻau. E faʻaaogaina i le tele o faʻaoga, e aofia ai paipa, faʻamalama uaea, ma fola.
4. Polystyrene (PS): O se polymer thermoplastic e lauiloa mo lona manino, faʻamalosi, ma le tau maualalo. E faʻaaogaina i le tele o faʻaoga, e aofia ai le afifiina, ipu faʻaaogaina, ma le faʻamalama.
5. Acrylonitrile-butadiene-styrene (ABS): O se polymer thermoplastic e lauiloa mo lona malosi, faigata, ma le tetee i le vevela ma le aʻafiaga. E faʻaaogaina i le tele o talosaga, e aofia ai vaega taʻavale, meataalo, ma mea tau eletise.

I le faaopoopo atu i nei polymers thermoplastic masani, e tele isi ituaiga o loʻo avanoa, e taʻitasi ma ona lava mea faʻapitoa ma faʻaoga. O isi faʻataʻitaʻiga e aofia ai le polycarbonate (PC), polyamide (PA), polyethylene terephthalate (PET), ma fluoropolymers pei ole polytetrafluoroethylene (PTFE).

I le aotelega, o polymers thermoplastic o se filifiliga sili ona lelei ma taugofie mo le tele o faʻaoga. O lo latou gafatia e faʻafefeteina ma toe faʻaleleia i le tele o taimi, faʻatasi ma le tele o mea faʻapitoa faʻapitoa ma masini, e avea ai i latou ma mea taua i le tele o pisinisi.
