I-Plastic Powder Coatings

Iyini i-plastic powder coatings?

I-Plastic powder coatings iwuhlobo lwe i-thermoplastic coating lokho kuhilela ukufaka impushana yepulasitiki eyomile endaweni engaphansi, eselapheka ngaphansi kokushisa ukuze yakhe isiphetho esiqinile, esiqinile, nesikhangayo. Le nqubo ijwayele ukusetshenziselwa ukumboza izindawo ezingaphezulu zensimbi ukuze zinikeze isivikelo ekonakalini, ekuhuzukeni, nasezimeni zezulu, kanye nokuthuthukisa ukubukeka kwazo kobuhle.

Inqubo yokugcoba i-powder ihilela izinyathelo ezimbalwa, kuqala ngokulungiswa kwe-substrate. Lokhu kuhilela ukuhlanza nokuphatha ngaphambili indawo engaphezulu ukuze kuqinisekiswe ukuthi ayinakho ukungcola, uwoyela, nokunye ukungcola okungase kuphazamise ukunamathela kwempushana. Okulandelayo, i-powder isetshenziswa ebusweni umbhede omanzi noma isibhamu se-electrostatic esibenza banamathele ku-substrate. I-substrate eboshwe ibe isishisiswe kuhhavini, encibilikisa impushana futhi ibangele ukuthi igeleze futhi yelaphe, yenze ukunamathela okubushelelezi, okulinganayo.

Izinzuzo

Enye yezinzuzo eziyinhloko ze-plastic powder coatings ukuthi ihambisana nemvelo. Ngokungafani nezingubo zoketshezi ezivamile, eziqukethe izincibilikisi ezingakhulula ama-VOC ayingozi (izinto eziphilayo ezishintshayo) emkhathini, izimbobo zempushana ngokuvamile azinakuncibilika futhi zikhiqiza imfucuza encane kakhulu. Lokhu kubenza babe inketho esimeme kakhudlwana futhi eco-friendly ukumboza anhlobonhlobo materials.

Enye inzuzo yepulasitiki ye-powder coatings ukuthi inikeza ukuvikelwa okuhle kakhulu kokugqwala. I-powder coating idala umgoqo phakathi kwe-substrate nemvelo, ivimbele umswakama nezinye izinto ezigqwalayo ukuthi zingangeni phezulu futhi zidale umonakalo. Lokhu kwenza izimbobo zempushana zilungele ukusetshenziswa ezindaweni ezinokhahlo noma ezonakalisayo, njengasolwandle noma izilungiselelo zezimboni.

Izinhlobo zepulasitiki ze-powder coatings

Esinye sezici ezibalulekile ezinquma ikhwalithi nokusebenza kwezingubo zepulasitiki ze-powder ukwakheka kwempushana ngokwayo. Iningi le-powder coating lenziwe kusuka ama-polymers we-thermoplastic, okudala isiphetho esiqinile, esiqinile phakathi nenqubo yokwelapha. Ama-polymers ajwayelekile asetshenziswa kuma-thermoplastic powder coatings afaka i-Polyethylene, i-polypropylene, i-polyester, i-polyvinyl chloride, i-polyether e-chlorinated, i-polyamide, i-cellulose, i-polyester, njll.

1. I-polyethylene powder coating inomsebenzi omuhle kakhulu wokulwa nokugqwala, ukumelana namakhemikhali, ukwahlukanisa ugesi okuhle kakhulu kanye nokumelana nemisebe ye-UV. Ingasetshenziselwa amathangi amakhemikhali, ama-impellers, amaphampu, izindonga zangaphakathi zamapayipi, amagobolondo angaphezulu, amashidi ensimbi, amanetha angaphakathi esiqandisini, izingxenye zemoto, njll. Ukukhubazeka kwawo amandla aphansi emishini kanye nokunamathela okubi ku-substrate.

2. Inayiloni powder enamathela, eyaziwa nangokuthi i-polyamide, inephoyinti eliphezulu lokuncibilika ngenxa yokuhlangana kwe-hydrogen phakathi kwama-athomu e-chlorine echungechungeni lwengqamuzana nama-athomu e-hydrogen asezigabeni zamaketango aseduze. Inayiloni inamandla amakhulu emishini, ukumelana komthelela, ubulukhuni, ukumelana nokugqoka, i-coefficient ephansi yokungqubuzana, ukumuncwa kothuli oluphansi, njll. Ingasetshenziselwa izingxenye ezikhethekile ezifana nama-impellers wepompo yamanzi, izingxenye zemishini yendwangu, izingxenye ze-piston zenjini ye-diesel, ama-propeller esikebhe sikaseyili, amasondo emoto, abakaki bezithuthuthu, imishini yezolimo, ukwakhiwa kanye nemishini yezemidlalo. I-nayiloni ye-powder coating ayinabo ubuthi, ayinambitheki, imelana namanzi anosawoti, isikhunta kanye namagciwane, futhi ilungele ukufafaza izingxenye zemboni yokudla, amapayipi amanzi okuphuza kanye nokupakisha ukudla.

3. I-Polyvinyl chloride powder ingenye yama-polymers asetshenziswa kakhulu angakhiqizwa ngobuningi ngemva kokusungulwa kwezimboni. Inokumelana okuhle kakhulu kwe-solvent, ukumelana nokugqwala okuhle emanzini ne-asidi, ukumelana nomthelela, ukumelana nesifutho sikasawoti, kunganqanda ukungcoliswa kokudla, futhi inokufakwa okuphezulu kokufuthwa kwe-electrostatic. Isetshenziselwa ikakhulukazi ukumboza amaphaneli ensimbi yensimbi, ifenisha yensimbi, imishini yamakhemikhali, njll.

4. I-Fluororesin powder coating ingalungiswa kusuka kuma-polymer ahlukahlukene ane-fluorinated, njenge-polytetrafluoroethylene (PTFE), i-polytrifluorochlorethylene (PTFCE), i-polyvinylidene fluoride (PVDF), njll. PTFE inezinga eliphezulu lokuncibilika elifinyelela ku-327℃ futhi lingasetshenziswa isikhathi eside ebangeni elingu -250~250℃. Iphinde ibe nokumelana nokugqwala okuhle kakhulu, ngisho nase-aqua regia, ukusebenza kahle kwe-dielectric, i-coefficient ephansi kakhulu ye-friction kanye nezindawo zokuzigcoba, ngakho-ke yaziwa ngokuthi "inkosi yepulasitiki". Isetshenziswa kakhulu ku-petroleum, i-chemical anti-corrosion coatings, i-sealing, izinto zokuthambisa ezithwalayo, izinto ze-elekthronikhi nezikagesi, ama-rails okwethula umkhumbi kanye nama-pan-non-stick coatings. I-PTFCE ishibhile kune PTFE, futhi izinga lokushisa lokucubungula lingehliswa. I-coating ingasetshenziswa isikhathi eside ngaphansi kwe-130 ℃. Ikhono layo lokumelana ne-alkali ne-fluor

Sekukonke, izimbotshana eziyimpuphu yepulasitiki iyinketho yokuhlanganisa eguquguqukayo nesebenzayo enikeza uhla lwezinzuzo nezinzuzo ngaphezu kwezingubo zoketshezi ezijwayelekile. Kusukela ezimpahleni zayo ezihambisana nemvelo kuya ekugqwaleni kwayo okuhle kakhulu kanye nokumelana nesimo sezulu, ukumbozwa ngempushana kuyinketho eyandayo ethandwa kakhulu ezimbonini nasezinsizeni ezahlukahlukene.
