Metal Waste Bin Modern Style Hotel Lobby for Hotera Use

Isu tinowanzo shandisa marudzi akasiyana emagaba emarara, uye kupfapfaidza magaba akapendwa marara inzira yakajairika yekugadzira. Kuenzaniswa neyechinyakare pfapfaidzo pendi emagaba emarara, kupfapfaidza pendi yemarara ine hunhu hwakanaka.

Pfapfaidza kuumba musimboti

Pfaya poda yekuputira pamusoro pechishandiso uchishandisa electrostatic poda yekupfapfaidza michina (electrostatic spray molding muchina). Pasi pechiito chemagetsi emagetsi, hupfu huchaita zvakafanana pamusoro pebasa rekushanda, kuumba poda yehupfu; Upfu hwehupfu hunopisa kupisa kwepamusoro-kupisa, kuenzanisa uye kuporesa, uye inova iyo yekupedzisira yekuputira nemigumisiro yakasiyana (mhando dzakasiyana dzehupfu); Mhedzisiro yekupfapfaidza yakakwirira pane yekupfapfaidza maitiro maererano nemagetsi simba, adhesion, corrosion resistance, kuchembera kuramba, nezvimwe.

Spray molding process kuyerera

1. Pre processing:

Chinangwa: Kubvisa mafuta, guruva, uye ngura kubva pamusoro pebasa rekushanda, uye kugadzira "phosphating layer" pamusoro pebasa rekushanda iro risingadziviriri uye rinogona kuwedzera kunamatira kwekuputira.

Matanho makuru ekuita: kubviswa kwemafuta, kubvisa ngura, phosphating, uye passivation. Mushure mekutanga kurapwa, iyo workpiece haina chete mafuta, ngura, kana guruva pamusoro, asi zvakare inogadzira yunifomu uye rough grey phosphating firimu pane yepakutanga sirivheri chena glossy pamusoro iyo isiri nyore kuita ngura, iyo inogona kudzivirira ngura uye kuwedzera kunamatira kweiyo spray coating.

2. Electrostatic spraying:

Chinangwa: Kupfapfaidza zvakaenzana poda yekuputira pamusoro pebasa rebasa. Zvidimbu zvebasa zvakakosha (kusanganisira nzvimbo dzinowanzo kudzivirirwa nemagetsi) zvinofanirwa kupfapfaidzwa uchishandisa yakakwirira-inoita electrostatic spray molding michina.

Matanho ekugadzira: Uchishandisa musimboti we electrostatic adsorption, dhizaini yehupfu yekuputira inopfapfaidzwa zvakaenzana pamusoro pechigamba chebasa. Hupfu hwakadonha hunodzoserwa kuburikidza nehurongwa hwekudzokorodza uye hunogona kushandiswa zvakare mushure mekusefa.

3. Kurapa kwekushisa kwepamusoro:

Chinangwa: Kupisa poda yekuputira pamusoro pebasa rekushanda kune tembiricha yakatarwa uye kuichengeta ichidziya kwenguva inoenderana, kuitira kunyunguduka, kuenzanisa, uye kurapa, nekudaro kuwana inodiwa pamusoro pekuita kwechigamba chebasa.

Matanho ekuita: Sunda chidimbu chebasa chakapfapfaidzwa muchoto chekubika, chipisa kusvika kune tembiricha yakafanotemerwa (kazhinji 185 madhigirii), uye chengeta ichidziya kwenguva inoenderana (15 maminitsi); Vhura choto uye ubudise kunze kuti utonhodze kuti uwane chigadzirwa chapera.

4. Decoration kurapwa:

Chinangwa: Kuwana yakakosha kutaridzika mhedzisiro yechikamu chebasa mushure mekupfapfaidza kwemagetsi, senge akasiyana mapatani ehuni, mapatani, uye gloss kuwedzera.

Maitiro matanho: Masking; Kutamisa kudhinda uye mamwe maitiro ekugadzirisa

Zvakanakira zvekupfapfaidza molding

1. Kana ichienzaniswa neyakajairwa pfapfaidzo pendi tekinoroji, tekinoroji yekupfapfaidza yemagetsi ine zvakanakira, senge kusada diluents, kusasvibisa kwezvakatipoteredza panguva yekuvaka, uye hapana chepfu kuhutano hwevanhu;

2. Iyo yekuputira ine yakanakisa kutaridzika kwemhando, kunamatira kwakasimba uye kusimba kwemagetsi;

3. Nguva pfupi yekurapa panguva yekupfapfaidza kuvaka;

4. Kudzivirirwa kwekuora uye kupfeka kusagadzikana kwekuputira kwakakwirira zvikuru; Hapana primer inodiwa;
