Kodi thermoplastics ndi chiyani?Kodi pali kusiyana kotani pakati pawo ndi mapulasitiki a thermosetting?

Thermoplastics imatanthawuza mapulasitiki omwe amafewa akatenthedwa ndikuuma akazizira.Mapulasitiki ambiri omwe timagwiritsa ntchito pamoyo wathu watsiku ndi tsiku ali m'gululi.Zikatenthedwa, zimafewa ndi kuyenderera, ndipo zikaziziritsidwa, zimauma.Njirayi ndi yosinthika ndipo ikhoza kubwerezedwa.

Thermoplastics si ofanana ndi pulasitiki thermosetting.

Thermoplastics ndi thermosetting pulasitiki ndi mitundu iwiri ikuluikulu ya mapulasitiki.

Makhalidwe a thermoplastics ndi awa:

Zikatenthedwa, zimafewetsa ndi kupunduka, ndipo zikaziziritsidwa, zimaumitsanso mmene zinalili poyamba.Njirayi ikhoza kubwerezedwa nthawi zambiri.

Mapangidwe a mamolekyu ndi mzere kapena nthambi, ndipo pali mphamvu yochepa chabe ya van der Waals pakati pa mamolekyu, ndipo palibe mankhwala ogwirizanitsa.

Thermoplastics woimira monga polyethylene, polypropylene, polystyrene, polyvinyl kolorayidi, etc.

Makhalidwe a mapulasitiki a thermosetting ndi awa:

Kukatenthedwa, chinthu chosasinthika cha mankhwala chidzachitika, kuchititsa kuti mamolekyu ake apange mawonekedwe atatu-dimensional cross-linked network, yomwe sidzafewetsanso ndi kupunduka.

Pali covalent zomangira pakati mamolekyu kupanga khola azithunzi atatu maukonde dongosolo.

Mapulasitiki oyimira thermosetting amaphatikizapo utomoni wa phenolic, epoxy resin, polyester resin, etc.

Kawirikawiri, thermoplastics ndipulasitiki ndi recyclable, pamene mapulasitiki a thermosetting ali ndi mphamvu zambiri komanso kukana kutentha, ndipo onsewa ali ndi ntchito zofunika kwambiri pamakampani apulasitiki.

Ndiye tiyenera kuchita bwanji ndi zinyalala zotentha zomwe zimapangidwa ndi thermoplastics popanga?Mwachitsanzo, zinyalala otentha kwa jekeseni akamaumba makampani mapulagi chingwe mphamvu ndi extrusion makampani mawaya ndi zingwe.Makina opangira jakisoni wamagetsi ndi ma Cable extruder amatulutsa zinyalala zotentha tsiku lililonse.ZisiyeniZAOGE wapadera yobwezeretsanso njira.ZAOGE pa intaneti pompopompo komanso kugwiritsa ntchito zinyalala nthawi yomweyo, zinthu zophwanyidwa ndi yunifolomu, zoyera, zopanda fumbi, zopanda kuipitsidwa, zapamwamba, zosakanikirana ndi zopangira kupanga zinthu zapamwamba kwambiri.
