Shot blasting uye derusting process yesimbi space frame

Kubvisa ngura kwezvimiro zvemuchadenga kunofanirwa kuitwa nepfuti kuputika kana maturusi emagetsi.Iyo ngura yekubvisa nhanho yesimbi space frame inofanirwa kusvika kuSa2.5 level, iyo roughness yepasi inofanira kuva 40-80μm, uye nzvimbo inopfuura chiyero inofanira kuva inopfuura 10%.Ita kubvisa ngura.Mushure mekubvisa ngura, jecha rinoyangarara rinofanira kubviswa zvachose, uye yekutanga yekutanga inofanira kupedzwa mukati memaawa gumi nemaviri.Kana paine ngura inoyangarara pamusoro, inofanira kubviswa nejecha kana maturusi emagetsi.

Iyo pendi yenhengo yesimbi yenzvimbo yesimbi inofanira kupfapfaidzwa.Iyo pende isati yapfapfaidza inofanira kumutswa zvakaenzana, uye haibvumirwi kuwedzera diluent pakuda.Kana iyo viscosity yepende yakakura kwazvo, huwandu hwakakodzera hwediluent hunogona kuwedzerwa, asi kusarudzwa kweasingapfuure 5% yedhirivhi kunofanirwa kuenderana nezvinopihwa zvependi chigadzirwa bhuku.Basa rekupenda rinofanirwa kuitwa munzvimbo yekuvanda, tembiricha yepakati inofanira kunge iri pakati pe5 ° C kusvika 35 ° C, hunyoro hwehukama hahufanire kunge hwakakura kupfuura 80%, uye tembiricha yepasi yezvikamu inofanira kunge iri 5 ° C yakakwirira kupfuura. dova.Mushure mokunge kuvhara kwaoma, kuonekwa kwepamusoro kwefirimu yepende kunofanira kuva yunifomu, yakapfava, yakapfava, isina kuputika, kuputika, kuvhara pasi, kuputika, pinholes, kuputika, kuputika uye tsvina yakanamatira., inofanira kugadziriswa nenguva.

Kuputika kwepfuti:

Shot blasting ndeye kushandisa simba repakati remushonga pamushini unoputika kana uchitenderera nekumhanya kukuru, uye kuputika kwepfuti kwakakwira zvakanyanya.
Iyo mutsara velocity yesimbi inopfurwa pamusoro pesimbi kuti igadziriswe, zvichikonzera kuvhuvhuta nekukuya mhedzisiro, uye chiyero che oxide chiri pamusoro pesimbi chinobviswa.
uye ngura, uye inobereka imwe kukasha.Shot blasting inoshanda zvakanyanya uye inogona kuitwa munzvimbo yakavharwa.
Shot blasting uye ngura yekubvisa giredhi;
(1) Kuputika kwepfuti uye kubvisa ngura.Iyo simbi yepamusoro inofanira kunge isina girisi inooneka kana tsvina uye isina yakasimba oxide chiyero, ngura uye pendi coating uye zvimwe zvakabatanidzwa;
(2) Kunyatsoputika pfuti uye kubvisa ngura.Iyo simbi yepamusoro inofanira kunge isina girisi inooneka kana tsvina uye isina yakasimba oxide scale, ngura uye pendi coatings nezvimwe zvakabatanidzwa;
(3) Kunyatso pfurwa kuputika uye kubvisa ngura.Nzvimbo yesimbi inofanira kunge isina girisi inooneka kana tsvina, chiyero, simbi dzakasungirirwa senge ngura uye pendi yependi, chero nzira dzakasara dzinofanira kunge dziine mavara mashoma muchimiro chemavara kana mitsetse;
(4) Kuputika kwepfuti uye kubvisa ngura kuita kuti nzvimbo yesimbi ichene.Nzvimbo yesimbi inofanira kunge isina mafuta anooneka kana tsvina, oxidation ganda, ngura uye pendi coatings nezvimwe zvakabatanidzwa, zvichiratidza yunifomu yesimbi inopenya;
