Imaphi ama-resin asetshenziswa embotsheni ye-thermoplastic powder

Kukhona ama-resin amathathu okuqala asetshenziswa ku i-thermoplastic powder coating, ama-vinyls, inayiloni nama-polyester. Lezi zinto zisetshenziselwa ezinye izinhlelo zokusebenza zokuxhumana nokudla, okokusebenza kwenkundla yokudlala, izinqola zokuthenga, amashelufu asesibhedlela nezinye izinhlelo zokusebenza.

Ambalwa ama-thermoplastic anobubanzi obubanzi bezakhiwo zokubukeka, izici zokusebenza nokuzinza okudingekayo ezinhlelweni ezisebenzisa izimpushana ze-thermoset.

Izimpushana ze-Thermoplastic ngokuvamile ziyizinto ezinesisindo samangqamuzana aphezulu ezidinga izinga lokushisa eliphezulu ukuze lincibilike futhi ligeleze. Ngokuvamile zisetshenziswa ngokufakwa kombhede omanzi futhi izingxenye zombili zishiswa ngaphambili futhi zishiswe ngemuva.

Iningi lezinsalela zempuphu ye-thermoplastic zinezakhiwo zokunamathela eziseceleni ukuze i-substrate iqhume futhi ifakwe kuqala ngaphambi kokufaka isicelo.

I-Thermoplastic powders i-fusible unomphela. Lokhu kusho ukuthi, uma sezishisiwe, zingashiselwa futhi futhi zigaywe kabusha zibe yizimo ezihlukene njengezifiso zomsebenzisi. Ngokuphambene, izimpushana ze-thermoset, uma sezishisiwe futhi zabunjwa zaba yizimo ezithile, azikwazi ukushisisa kabusha ngaphandle kokushiswa noma ukuphuka. Incazelo yamakhemikhali yalokhu kuziphatha iwukuthi ama-molecule aku-thermoplastics akhangana kancane kanti ku-thermoset axhunywe iketango.

Amandla kaVan der Waals aheha futhi abambe ama-molecule ndawonye. Njengoba i-thermoplastics ichazwa amandla abuthakathaka e-van der Waals, amaketanga amangqamuzana akha ama-thermoplastic awenza akwazi ukwanda futhi aguquguquke. Ngakolunye uhlangothi, uma izimpushana ze-thermosetting sezishisisiwe, zisabela ngokwamakhemikhali, futhi inhlanganisela entsha eyakhiwe ibonakala ngamandla aqinile e-van der Waals. Esikhundleni sokwenza amaketanga amade, akha ama-molecule ayikristale ngokwemvelo, okwenza umkhiqizo ube nzima ukuwusebenzisa kabusha noma ukuncibilika kabusha uma ususelashiwe.
