Dip Powder Coating uye Spray Powder Coating

1. Mafungiro akasiyana

1) Spray Powder coating:

Spray Powder coating inzira yekurapa pamusoro inosanganisira kumwaya hupfu pachigadzirwa. Iyo poda inowanzoreva thermosetting poda coating. Iyo yepamusoro yezvigadzirwa zvakaputirwa nehupfu yakaoma uye yakatsetseka kupfuura yezvigadzirwa zvakanyungudutswa. Majenareta eElectrostatic anoshandiswa kuchaja hupfu, hunobva hwakwezvwa pamusoro pesimbi ndiro. Mushure mekubika pa180-220 ℃, hupfu hunonyunguduka uye hunonamatira kune simbi pamusoro. Zvigadzirwa zvakaputirwa nehupfu zvinowanzoshandiswa kushandiswa kwemukati, uye firimu repende rine flat kana matte kana art effect.

2) Dip poda coatings:

Dip poda coating inosanganisira kudziyisa simbi uye yakaenzana kuiputira nehupfu hwepurasitiki kuita firimu repurasitiki, kana kudziyisa nekunyika simbi mudhipi yekukoira mhinduro kuti itonhore uye kugadzira firimu repurasitiki pamusoro pesimbi. Hupfu kazhinji hunoreva thermoplastic powder coating. Dip coating inogona kukamurwa kuita inopisa dip coating uye inotonhora dip coating, depekutarisisa kuti kudziya kunodiwa here, uye kupfekedza dip yemvura uye kupotera kwepoda dip, depekutarisisa zvinhu zvakashandiswa.

2. Nzira dzakasiyana dzekugadzirisa

1) Kune akasiyana marudzi ekupfapfaidza poda yekupotera, senge acrylic hupfu, polyester hupfu, uye epoxy polyester hupfu. Kupfapfaidza poda yekuputira ine mhando yepamusoro yechigadzirwa uye huremu kupfuura dip poda yekuputira, asi iyo chigadzirwa chepamusoro chakanaka uye chakatsetseka kune ese ari maviri nzira.

2) Dip coating yakachipa pane kupfapfaidza poda yekuputira nekuti mutengo we dip coating poda wakaderera pane wesimbi. Dip poda coating ine zvakanakira anti-corrosion uye kudzivirira ngura, asidhi uye alkali kuramba, hunyoro kuramba, insulation, kubata kwakanaka, kuchengetedza kwezvakatipoteredza, uye hupenyu hurefu hwebasa. Dip coating ukobvu hunowanzo kukora kupfuura kupfapfaidza hupfu hwekupfapfaidza, nehukobvu hunopfuura 400 microns zvichienzaniswa ne50-200 microns yekupfapfaidza poda yekupotera.

1) Dip coating powders:

①Civil poda coating: inonyanya kushandiswa kupfekedza marekeni embatya, mabhasikoro, tswanda, midziyo yemukicheni, nezvimwewo. Vane kuyerera kwakanaka, kupenya, uye kusimba.

②Engineering powder coating: inoshandiswa kuvharisa mugwagwa mukuru nenjanji, mainjiniya ekanzuru, zviridzwa nemamita, magidhi esupamaketi, masherufu mumafiriji, tambo, nezvimwe zvinhu zvakasiyana-siyana, nezvimwewo. Izvo zvinogara zvakasimba uye zvinoramba kuita ngura.

2) Dip coating musimboti:

Dip coating inzira yekudziya inosanganisira preheating simbi, kuinyika mumushonga wekuputira, nekuirapa. Panguva yekunyura, simbi inopisa inonamatira kune zvinhu zvakapoteredza. Kupisa kwesimbi, kunowedzera nguva yekunyura, uye kukora kwekupfeka. Kupisa uye chimiro chemhinduro yekuputira zvinotarisa huwandu hweplasticizer inonamatira kune simbi. Dip coating inogona kugadzira zvinoshamisa maumbirwo. Maitiro chaiwo anosanganisira kuwedzera poda coating kune yepasi porous mudziyo (flow tank), iyo inozobvongodzwa nemhepo yakamanikidzwa inobatwa neinofuridza kuti iwane "fluidized state", ichiita hupfu hwakafanana hwakagoverwa.

3. Kufanana 

Ose ari maviri maitiro ekurapa kwepamusoro. Mavara enzira mbiri idzi anogona kuve yero, tsvuku, chena, bhuruu, girini, uye dema.
