Isigaba: I-Powder Coat Guide
Ingabe unayo imibuzo yokugcoba impushana mayelana nemishini yokumboza impushana, ukufakwa kwempushana, impahla yempushana? Ingabe unokungabaza ngephrojekthi yakho yejazi lempushana, lapha umhlahlandlela ophelele wejazi lempushana ungakusiza ukuthi uthole impendulo eyanelisayo noma isisombululo.
Izinkinga ngokufaka impushana enamathela endaweni enothayela
I-polyester powder coating phezu kwensimbi yediphu eshisayo inikeza i-architectu yezinga eliphezulural ukuqeda izinto zensimbi ezinezici ezinhle kakhulu zesimo sezulu somkhathi.Umkhiqizo ofakwe ngempushana uqinisekisa ukuqina okuphezulu kwezingxenye zensimbi, ezizokwenzaralhlinzeka ngokugqwala iminyaka engu-50+ ku-architectu eminingiral izicelo. Noma kunjalo kusenezinkinga ezithile phakathi nalolu hlelo lokusebenza. Izindawo ezishisayo ze-dip galvanized ziye zamukelwa njengokunzima ukuhlanganisa impushana kusukela ubuchwepheshe baqala ukwenziwa ngeminyaka yawo-1960. Ama-Industrial Galvanizers aqale ucwaningo kuFunda kabanzi …
Ungakuvimbela kanjani ukuqhuma kothuli lwempushana
Ukuqhuma kungavinjelwa uma kokubili noma esinye sezimo Umkhawulo Weziqhumane kanye Nomthombo wokuthungela kugwenywa. Uhlelo lokumboza impushana kufanele lwenzelwe ukuvimbela zombili izimo ukwenzeka, kodwa ngenxa yobunzima bokuqeda ngokuphelele imithombo yokuthungela, ukuthembela okwengeziwe kufanele kubekwe ekuvimbeleni ukugxila kweziqhumane zempushana. Lokhu kungafezwa ngokuqinisekisa ukuthi impushana ekugxilweni komoya igcinwa ngaphansi kuka-50% we-Lower Explosive Limit(LEL). Kunqunywe ama-LEL ebangeniFunda kabanzi …
Izimbangela zokuqhuma kothuli kanye nezingozi zomlilo ngesikhathi sokukhiqiza i-powder coating
Izembatho zempushana ziyizinto ezinhle ze-organic, zingadala ukuqhuma kothuli. Kungase kuqhume uthuli lapho izimo ezilandelayo zenzeka ngesikhathi esisodwa. Imithombo yokuthungela ikhona, okuhlanganisa: (a) izindawo ezishisayo noma amalangabi;(b) ukukhishwa kukagesi noma izinhlansi;(c) ukuchithwa kwe-electrostatic. Ukuhlangana kothuli emoyeni kuphakathi kwe-Lower Explosive Limit (LEL) kanye ne-Upper Explosion Limit (UEL). lapho ungqimba lwempushana egcotshiwe noma ifu lihlangana neFunda kabanzi …
Ukwenziwa Kwezimbozo Zempushana
Kala kanye nokuxuba (impahla eluhlaza, efana nezinsalela, okokuqinisa, izingulube, okokugcwalisa, njll) Ukugaywa Kwenqubo Yokukhipha kanye Nokuhlunga
I-Phosphating Conversion Coatings
Ukwelashwa kwangaphambili okwaziwayo kwama-substrates ensimbi ngaphambi nje kokufaka izimbotshana zempushana kuyi-phosphating engahluka ngesisindo sokumboza. Uma sikhulu isisindo sokuguqula ukuguqulwa sikhulu izinga lokumelana nokugqwala elizuziwe; ephansi isisindo enamathela ngcono izakhiwo mechanical. Ngakho-ke kuyadingeka ukukhetha ukuvumelana phakathi kwezakhiwo zemishini kanye nokumelana nokugqwala. Izisindo eziphezulu ze-phosphate zokumboza zingase zibangele izinkinga nge-powder coatings kulokho kuphuka kwekristalu kungenzeka lapho ukumbozwa kwenziwa.Funda kabanzi …
