Ngabe i-rust-brow-powtha powder coating ithuthukisa kanjani ukuqina kwamaloli okulahla insimbi?

Emkhakheni wezinto zokuhamba ezisebenza kanzima, amaloli okulahla insimbi, njengemishini ebalulekile, yenza umsebenzi obalulekile wokuhambisa izimpahla eziningi ezifana nesihlabathi, amatshe amatshe, no-ore. Imvelo yayo yokusebenza inokhahlo, futhi sekuyisikhathi eside ibhekene nezimo zomgwaqo eziyinkimbinkimbi, umthelela womthwalo osindayo, kanye nokuguguleka kwezinto ezibonakalayo, okuholela ezinkingeni ezivame kakhulu njengokugqwala komzimba wemoto kanye nokukhathala kwemoto. Izinqubo zenhlanganisela zendabuko zinzima ukufeza izidingo zokusetshenziswa okuphezulu kakhulu ngenxa yokumelana kahle kwesimo sezulu nokusebenza okunganele kokulwa nokukhulisa. Ukuvela kobuchwepheshe be-rust-bufrew powtha powtha technology kunikeza isixazululo esisha kule nkinga.

I-Rust-proof powder coating impahla esebenza kahle yokusebenzisana nge-thermosetting resin njenge-matrix ne-metal oxide njenge-filler. Isebenzisa ubuchwepheshe be-electrostatic adsorption ukuze bafafaze ngokulinganayo i-powder ekhokhiswayo endaweni ephethwe ngensimbi esengaphambi kokuphathwa, bese yenza ukuhlanganiswa okuningana ngemuva kokwelapha okushisa okuphezulu. Uma kuqhathaniswa nezimbozo ezisuselwa kwiSolvent, lobu buchwepheshe bunezinzuzo ezintathu ezibalulekile:
Ukuvikelwa Kwezemvelo: Ayikho i-turatile organic complic compact (VOC) Emission ngesikhathi senqubo yokwelapha, ehlangabezana namazinga okukhiqiza aluhlaza.
Ukumelana Nesimo Sezulu: I-coating ayiminyene futhi ingeyona-porous, engavimba ngempumelelo imithombo yezindaba enamandla efana nomphunga wamanzi kanye nokufafaza usawoti okusobala, futhi kunosawoti osawoti wokufafaza amahora angaphezu kwe-1000.
Izakhiwo zemishini: Ngemuva kokuphulukisa, ubulukhuni be-coating bufinyelela ngaphezu kwe-4h, futhi amandla omthelela adlula ama-50kg · cm, akwazi ukubekezelela ukugqokwa kwemishini yokulayishwa okugcwele.
Indlela yokuthuthukisa ukuqina kwamaloli okulahla udoti ngokulwa ne-powder coating
Ukulahla iloli Amabhokisi adinga ukubekezelela umthelela osheshayo wamathani amaningana wezimpahla lapho uphakamisa futhi ulayisha. I-anti-Rust powder coating yakha ungqimba lwe-metallurgical bonding nge-substrate, okuthuthukisa kakhulu ukumelana nokukhathala kwezitho zesakhiwo. Isibonelo, ekuxhumekeni phakathi kogongolo lwe-Longitudinal kanye nogongolo lwesiphambano sebhokisi, ukunamathela kunganciphisa isici sokuhlushwa kwengcindezelo ngo-30%, ukubambezele ngempumelelo ukusakazeka kwemifantu.
Izinga lokugqwala lezimbobo zendabuko lingafinyelela kuma-40% kungakapheli iminyaka emi-3 ezokuhamba ze-ore, ngenkathi ukuhlanganiswa kwe-anti-bust powder kunciphisa inani lokugqwala liye ku-0.02mm / ngonyaka ngomphumela wokuvikela. Ukuthatha imodeli ethile yeloli yokulahla udoti njengesibonelo, ngemuva kokuthola lobu buchwepheshe, impilo yenkonzo yezakhi ezisemqoka inwetshiwe kusukela eminyakeni engu-5 kuya ngaphezulu kweminyaka eyi-8, futhi izindleko zokulungiswa komjikelezo wempilo yonke zincishiswa cishe ngama-35%.

Impahla yokuzipholisa ye-coating inganciphisa imvamisa yokulungisa imali. I-coeffient yayo yokunwebeka isondelene nelensimbi (12 × 10⁻⁶ / ℃), futhi igcina ukuqina ngaphansi kwezimo zokusebenza kuka-40 ℃ kuya ku-120 ℃, igweme ukuqhekeka kwe-coating okubangelwa umehluko wokushisa. Inkampani ye-Logistics ibike ukuthi amahora wonyaka wesondlo amaloli okulahla udoti ngokulwa kwe-powder coatis ancishiswa ngamahora angaphezu kwama-200.

Ukusebenza kwe-anti-rust powder coating ngaphansi kwezimo ezikhethekile zokusebenza
Ezimweni zokusebenza zasolwandle noma ezisogwini lolwandle, i-nano-scale zinc onide filler ezingezwe ku-coating ingakha umgoqo ongokomzimba, ehlanganiswe nokuhlekisa kokuphambukiswa kweChromate, ukufezekisa ukuvikelwa kokugqwala kwe-synergistic. Imininingwane yangempela evumelana nokuthi ngemuva kwamahora angama-2000 okuvezwa egumbini lokuhlola likasawoti wesawoti, i-adhesion ehlanganayo isagcina i-5th Level Standard (GB / T 9286-1998).

Ngesikhathi sokulayisha i-ore nokulayisha, ifilimu eliminyene le-oxide eyakhiwe endaweni yokuhlangana lingamelana nomthelela we-gravel. Isivivinyo se-SAnd Fall Wear (ASTM G65) siqinisekisa ukuthi ukumelana kwayo kokugqoka kuphakeme kaphindwe ka-2 kunalokho kwengubo yendabuko, kuqinisekiswe ukuthi phansi kwebhokisi lemoto kuhlala kugcwele ukulayisha nokulayisha.

Ebusika eNyakatho, ukunamathela kudinga ukubekezelela eminye imiphumela yamazinga okushisa aphansi angu -30 ° C kanye nokushisa kwemisebe kusuka ekulayishweni nasekulayisheyo. Izinga lokushisa layo le-Glass Transion (TG) lifinyelela ku-180 ° C, futhi lihlala livumelana nezimo emazingeni okushisa aphansi ku--40 ° C, ukugwema ukukhonkotha kombambo ngenxa yokungafani.

Umthelela wokulwa nempuphu yempuphu yempuphu yenani lomjikelezo wempilo yamaloli okulahla amanzi
Inqubo ye-powder coating ifaka izinqubo ezintathu ezinkulu: ukwenziwa kokuhle (ukuhlekisa, phosphating), ukufafaza nge-electrostatic, nokwelapha. Isikhathi se-coating semoto eyodwa singamaminithi angama-45 kuphela, okuphumelela kakhudlwana kunenqubo yendabuko. Isithando somlilo sisebenzisa ubuchwepheshe bokufudumala kwemisebe ye-infrared infrared, okunciphisa ukusetshenziswa kwamandla ngo-40%, ukubhekana nezidingo zokulondolozwa kwamandla nokuncishiswa kokuphuma kwamandla.

Ukumelana nokugqwala kwamakhemikhali kwe-coating kungamelana nokuguguleka kwemvula ye-acid, ama-ejenti we-snoine ancibilike, lapho izimoto ezisebenza nge-chlorchering spectroscopy (es) zibonisa ukuthi i-modulus yayo ye-chlorroscopy (Electle) i-modulunce ibonisa ukuthi i-modulus yayo yokuvikela i-chlodance ingaphezulu kwe-10⁵⁵, evikela ngempumelelo i-substrate.

I-coating ingavuselelwa futhi isetshenziswe kabusha, futhi ubumsulwa bensimbi bufinyelela kuma-99.5% ngemuva kokususwa kokupenda, okuhlangabezana nezidingo zomnotho oyindilinga. Izindleko zayo zokulahla imfucuza ziphansi kwaphansi kwaphansi kunalezo ezimbozo ezisuselwa ku-solvent, zifinyelela ukuphathwa okuluhlaza kuyo yonke impilo yomjikelezo.
