Yintoni thermoplastics?

I-Thermoplastics ludidi lweeplastiki eziyiplastiki kubushushu obuthile, ziqina emva kokupholisa, kwaye ziyakwaziepekule nkqubo. Ulwakhiwo lwemolekyuli lubonakaliswa ngumgca wepolymer ikhompawundi, ngokuqhelekileyo ayinamaqela asebenzayo, kwaye ayihambi kwi-linear intermolecular crosslinking xa ishushu. Iimveliso ezilahlwayo zinokuphinda zisetyenziselwe kwiimveliso ezintsha emva kokurisayikilishwa. Iindidi eziphambili ziyi-polyolefins (i-vinyls, i-olefins, i-styrenes, i-acrylates, i-olefins ene-fluorine, njl.), i-cellulose, i-polyester polyester kunye ne-Aromatic heterocyclic polymers, njl.

inkcazelo

Iiplastiki zeThermoplastic zezona zisetyenziswa kakhulu. Ziyilwe kunye ne-thermoplastic resin njengeyona nto iphambili kunye nezongezo ezahlukeneyo. Ngaphantsi kweemeko ezithile zokushisa, iiplastiki zinokuthambisa okanye zinyibilike kuyo nayiphi na imilo, kwaye imilo ihlala ingatshintshi emva kokupholisa; le meko ingaba repeated amaxesha amaninzi kwaye ihlala ineplastiki, kwaye le repeUtshintsho lutshintsho lomzimba kuphela, olubizwa ngokuba yi-thermoplastic. iplastiki.

Kubandakanya i-polyethylene, polypropylene, i-polyvinyl chloride, i-polystyrene, i-polyoxymethylene, i-polycarbonate, i-polyamide, iiplastiki ze-acrylic, ezinye ii-polyolefins kunye ne-copolymers yazo, i-polysulfone, i-polyphenylene ether

Ukuhlelwa koLwakhiwo

I-Thermoplastics inokohlulwa ibe yiplastiki yenjongo ngokubanzi, iiplastiki zobunjineli, kunye neeplastiki ezikhethekileyo ngokweempawu zabo zokusebenza, uluhlu olubanzi lokusetyenziswa, kunye nokuguquguquka kobuchwephesha bokubumba.

Iimpawu eziphambili zeeplastiki zenjongo jikelele zezi: ukusetyenziswa okubanzi, ukusetyenzwa kakuhle, kunye nokusebenza kakuhle okubanzi. Njenge polyethylene (PE)Ipolyvinyl chloride (PVC), i-polypropylene (PP), i-polystyrene (PS), i-acrylonitrile-butadiene-styrene (ABS) iyaziwa nangokuthi "iiplastiki ezintlanu zenjongo jikelele".

Iimpawu zeeplastiki zobunjineli kunye neeplastiki ezikhethekileyo zezi: izakhiwo ezithile kunye neepropati zeepolymers eziphezulu zibalaseleyo, okanye iteknoloji yokucubungula i-molding inzima kakhulu, njl., kwaye ihlala isetyenziselwa ubunjineli obuchwephesha okanye amasimi akhethekileyo kunye nezihlandlo. Iiplastiki eziphambili zobunjineli zezi: inayiloni (Nayiloni), i-polycarbonate (iPC), i-polyurethane (PU), i-polytetrafluoroethylene (iTeflon, PTFE), i-polyethylene terephthalate (PET), njl., iiPlastiki ezikhethekileyo ezifana ne "synthetic heart valves" kunye "namalungu okufakelwa" njenge "polymers zonyango".
