Yintoni thermoplastics?Yintoni umahluko phakathi kwabo kunye neplastiki ye-thermosetting?

I-Thermoplastics ibhekisela kwiiplastiki ezithambileyo xa zifudunyezwa kwaye ziqina xa zipholile.Uninzi lweeplastiki esizisebenzisayo kubomi bethu bemihla ngemihla zikolu didi.Xa zishushu, ziyathamba zize zihambe, yaye xa zipholile, ziqina.Le nkqubo ibuyiselwa umva kwaye inokuphinda iphindwe.

I-Thermoplastics ayilingani neplastiki ye-thermosetting.

Iiplastiki ze-Thermoplastic kunye ne-thermosetting zimbini iintlobo eziphambili ezahlukeneyo zeeplastiki.

Iimpawu ze-thermoplastic zezi:

Xa zishushu, ziyathamba zize zigqwese, yaye xa zipholile, zibuyela kwimo yazo yangaphambili.Le nkqubo inokuphinda iphindwe kaninzi.

Ulwakhiwo lwemolekyuli lunomgca okanye lunamasebe, kwaye kukho kuphela amandla abuthathaka e-van der Waals phakathi kweeathom, kwaye akukho khemikhali yokudibanisa ukuwela.

I-thermoplastics emeleyo ibandakanya i-polyethylene, i-polypropylene, i-polystyrene, i-polyvinyl chloride, njl.

Iimpawu zeplastiki ye-thermosetting zezi:

Xa kushushu, ukusabela kweekhemikhali ezingenakuguqulwa kuya kwenzeka, okubangela ukuba iimolekyuli zayo zenze i-three-dimensional cross-linked network structure, engasayi kuphinda ithobe kwaye iguqule.

Kukho iibhondi covalent phakathi iimolekyuli ukwenza i-stable ezintathu-dimensional isakhiwo womnatha.

Iiplastiki ezimele i-thermosetting ziquka i-phenolic resin, i-epoxy resin, i-polyester resin, njl.

Ngokubanzi, thermoplasticszeplastiki kwaye ziphinde zisetyenziswe, ngelixa iiplastiki ze-thermosetting zinamandla amakhulu kunye nokumelana nobushushu, kwaye zombini zinezicelo ezibalulekileyo kwishishini leplastiki.

Ngoko ke kufuneka sijongane njani nenkunkuma eshushu eyenziwa yi-thermoplastics kwinkqubo yokuvelisa?Umzekelo, inkunkuma eshushu evela kwishishini lokubumba inaliti yeeplagi zentambo zamandla kunye neshishini lokukhupha iintambo kunye neentambo.Oomatshini bokubumba inaliti yentambo yamandla kunye neCable extruders ziya kuvelisa inkunkuma eshushu yonke imihla.YiyekeZAOGE isisombululo esisodwa sokurisayikilishwa.I-ZAOGE yokusila ngoko nangoko kwi-intanethi nokusetyenziswa kwenkunkuma eshushu ngoko nangoko, izinto ezityumkileyo zifana, zicocekile, azinathuli, azingcolisi, umgangatho ophezulu, zixutywe kunye nezinto eziluhlaza ukuvelisa iimveliso eziphezulu.
