I-Plastic Powder Coatings

Iyini i-plastic powder coatings?

Izembozo zempuphu yepulasitiki uhlobo lwezembozo ze-thermoplastic oluhilela ukufaka i-powder yepulasitiki eyomile endaweni engaphansi komhlaba, bese ipholiswa ngaphansi kokushisa ukuze yakhe isiphetho esiqinile, esihlala isikhathi eside, nesikhangayo. Le nqubo ivame ukusetshenziselwa ukumboza izindawo zensimbi ukuze kuvikelwe ekugqwaleni, ekugugulekeni nasekugugulekeni, kanye nokuthuthukisa ukubukeka kwazo okuhle.

Inqubo yokumboza ngempuphu ihilela izinyathelo eziningana, kuqala ngokulungiswa kwe-substrate. Lokhu kuhilela ukuhlanza nokulungisa ubuso kusengaphambili ukuqinisekisa ukuthi abunawo ukungcola, uwoyela, nezinye izinto ezingcolisayo ezingaphazamisa ukunamathela kwempuphu. Okulandelayo, impuphu ifakwa ebusweni kusetshenziswa umbhede omanzi noma isibhamu se-electrostatic esibangela ukuba zinamathele ku-substrate. I-substrate embozwe ibe isishiswa kuhhavini, okuncibilikisa impuphu bese ibangela ukuthi igeleze futhi iphole, kwakhiwe i-coating ebushelelezi, elinganayo.

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 kanye nokusebenza kwezembozo zepulasitiki ezifakwe i-powder ukwakheka kwe-powder uqobo. Izembozo eziningi ze-powder zenziwe ngama -polymer e-thermoplastic , adala isiphetho esiqinile nesihlala isikhathi eside ngesikhathi senqubo yokulungisa. Ama-polymer avamile asetshenziswa kwezembozo ze-thermoplastic ezifakwe i-powder afaka i-Polyethylene, i-polypropylene , i-polyester, i-polyvinyl chloride, i-chlorinated polyether, i-polyamide, i-cellulose, i-polyester, njll.

1. Isembozo sempuphu ye-polyethylene sinomsebenzi omuhle kakhulu wokulwa nokugqwala, ukumelana namakhemikhali, ukuvikela ugesi okuhle kakhulu kanye nokumelana nemisebe ye-UV. Singasetshenziswa kumathangi amakhemikhali, ama-impeller, amaphampu, izindonga zangaphakathi zamapayipi, amagobolondo angaphezulu, amashidi ensimbi, amanetha angaphakathi esiqandisini, izingxenye zemoto, njll. Isici saso amandla aphansi okusebenza kanye nokunamathela okubi ku-substrate.

2. Ingubo yempuphu yenayiloni , eyaziwa nangokuthi i-polyamide, inezinga eliphezulu lokuncibilika ngenxa yokubopha kwe-hydrogen phakathi kwama-athomu e-chlorine ku-molecule chain kanye nama-athomu e-hydrogen ku-chain sections aseduze. I-nayiloni inamandla aphezulu okusebenza, ukumelana nokushayisana, ubulukhuni, ukumelana nokuguguleka, i-coefficient ephansi yokungqubuzana, ukumuncwa kothuli okuphansi, njll. Ingasetshenziswa ezingxenyeni ezikhethekile njenge-water pump impellers, izingxenye zemishini yendwangu, izingxenye ze-piston zokuqala injini yedizili, ama-propeller esikebheni, amasondo ezimoto, ama-bracket esithuthuthu, imishini yezolimo, imishini yokwakha neyezemidlalo. Ingubo yempuphu yenayiloni ayinabo ubuthi, ayinambitheki, imelana namanzi anosawoti, isikhunta kanye namagciwane, futhi ifanelekela ukufafaza izingxenye zemboni yokudla, amapayipi amanzi okuphuza kanye nokupakishwa kokudla.

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.
