Powder Coating Materials Nhasi Uye Mangwana

Nhasi, vagadziri ve powder coating zvinhu zvakagadzirisa matambudziko ekare, uye tsvakurudzo inoenderera mberi uye teknolojia inoramba ichiputsa zvishoma zvipingamupinyi zvakasara zvekuputira upfu.

Powder Coating Materials

Kubudirira kwakanyanya kwezvinhu kwave kuvandudzwa kweinjiniya resin masisitimu akagadzirirwa kusangana neakasiyana uye chaiwo zvinodiwa zveindasitiri yekupedzisa simbi. Epoxy resins yaishandiswa chete mukati memakore ekutanga eiyo thermosetting poda coating uye ichiri kushandiswa zvakanyanya nhasi. Kushandiswa kwepolyester resins kuri kukura nekukurumidza mumusika wekuNorth America uye maacrylics chinhu chikuru kune vazhinji vashandisi vekupedzisira, senge midziyo uye maindasitiri emotokari.

Mapoda anowanikwa nekunakisisa kuramba ngura, kupisa, kukanganisa, uye abrasion. ruvara selec?tion haina muganho ine yakakwirira uye yakaderera gloss, uye yakajeka inopedzisa iripo. Kusarudzwa kwemavara kunotangira kubva pakatsetseka kusvika kune yakaunyana kana matte kupera. Ukobvu hwemafirimu hunogonawo kusiirwa kuti huenderane nezvinodiwa zvemashandisirwo chaiwo.

Kuvandudzwa kwemasisitimu eresin kwakakonzera iyo epoxy-polyester hybrid, iyo inopa yakatetepa-layer, yakaderera- ~ inorapa poda coating. Kufambira mberi mupolyester uye acrylic resin kwakavandudza kunze kusimba kweaya masisitimu. Kunyanya kufambira mberi mune resin tekinoroji kunosanganisira:

• Mutete-layer poda coatings kubva epoxy-polyester mahybrids anopa maapplication ari pakati pe1 kusvika 1.2 mils yemavara ane simba rekuhwanda rakanaka. Aya mafirimu matete parizvino akakodzera kushandiswa kwemukati chete. Mafirimu akaonda kwazvo, angangoda kugayiwa kwehupfu, anogona kunge akaderera se 0.5 mils.
• Low-tembiricha poda coatings. Hupfu hwekufukidzira nehupamhi reactivity hwakagadziridzwa kurapa patembiricha yakaderera se250°F (121°C). Mapoda akaderera akadaro anogonesa kumhanya kwemutsara wepamusoro, kuwedzera huwandu hwekugadzira pasina kupira kunze kusimba. Ivo zvakare vanowedzera nhamba ye substrates inogona kuve yakafukidzwa nehupfu, senge mamwe mapurasitiki uye zvigadzirwa zvehuni.
• Texture poda coatings. Aya mabhanhire iye zvino anotangira kubva pakunaka kwemavara ane gloss yakaderera uye kupikisa kwepamusoro kune abrasion uye scratches, kusvika kune rough texture inobatsira pakuvanza nzvimbo isina kuenzana yemamwe ma substrates. Aya machira ekushongedza akave nekunatsiridza kukuru kana achienzaniswa neawo macounter zvikamu zveanomweral makore apfuura.
• Low-gloss powder coatings. Izvozvi zvinogoneka kuderedza gloss values ​​pasina kuderedza kuchinjika, mechanical properties, kana kuonekwa kwehupfu. Gloss values ​​inogona kudzikiswa kusvika 1% kana zvishoma mu epoxies yakachena. Iyo yakaderera kupenya mumamiriro ekunze-inodzivirira polyester masisitimu inosvika 5%.
• Metallic powder coatings dziripo pari zvino mumarudzi akasiyana-siyana. Mazhinji eaya esimbi masisitimu akakodzera kushandiswa kwekunze. Nekusimba kwekunze kwekunze, jasi rehupfu rakajeka rinowanzoiswa pamusoro pesimbi yesimbi. Kuedza kwakanangana nekugadzira machisi akakwana eakajairwa anodizing mavara kuti asangane nezvinodiwa zvemusika wealuminium extrusion. Chimwe chiitiko chichangobva kuitika ndechekutsiviwa kwesimbi flakes nezvinhu zvisina-ferrous semica.
• Bvisa poda coatings yakave nekunatsiridza kukuru mumaseve apfuuraral makore maererano nekuyerera, kujeka, uye kuramba mamiriro ekunze. Zvichienderana nepolyester uye acrylic resin, idzi hupfu dzakajeka dzinoisa zviyero zvemhando mumavhiri emotokari, zvigadziriso zvepombi, fenicha, uye hardware.
• High weatherability poda coatings. Kufambira mberi kunoshamisa kwakaitwa mukugadzira polyester uye acrylic resin masisitimu ane yakanakisa kwenguva refu yemamiriro ekunze kuti asangane newaranti yakawedzerwa inopihwa nevagadziri. Zvakare pasi pekuvandudzwa kune fluorocarbon-based powders, iyo inofananidza kana kudarika mamiriro ekunze emvura fluorocarbons, ine mari inoshandiswa inobatsira kune hupfu.

Powder coating yavewo kupedzisa kunoshanda kune zvigadzirwa zvinogadzira akakosha kupisa mazinga, senge ekutengesa mwenje zvigadziriso, uye se primer yegrill top, iyo inoshanda sechigadziko chejasi remvura repamusoro.

Vagadziri vehupfu vanoramba vachigadzira resin yakakwana uye kurapa maajenti magadzirirwo. Kuedza kwazvino kutsvagisa kwakanangana nekugadzira nekuvandudza yakaderera-mutengo, yakaderera-kupodza poda kubatsira kuwedzera hupfu hwekuputira application kune masubstrates matsva. Basa rinoenderera mberi mukugadzira poda inosimba zvakanyanya nekukwirira kwemamiriro ekunze kuti ishandiswe zvakanyanya kunze, ichiratidza kusada kwechaki kana kupera muchiedza chezuva.
