TAA tekinoroji department inotenda kuti pretreatment yepasi inoita basa rakakosha mukuita kwejasi.Pakati pezvinhu zvakawanda zvinokanganisa mashandiro ejasi, pretreatment yepamusoro ndiyo inonyanya kukosha.

Surface pretreatment ibasa rekutanga

Surface pretreatment inogona kugadzira mamiriro ekupfekedza nekuita kwakanakisa muzvikamu zviviri: mune mechanical, inopa kushata kwepamusoro kwejasi;Uye mukemikari, inogadzira mamorekuru ejasi padhuze nepamusoro pesimbi substrate.

Kunda kukanganisa kwakashata kwepamusoro pepamusoronokuticoating

Kana iyo yepamusoro yakatsetseka, hapazove nekunamira kwakanaka pakati pekupfekedza uye nepamusoro, uye kupfeka kuri pamusoro kunogona kubviswa zvisingaite.Pane zvinopesana, kana pamusoro pechigadzirwa chebasa chakashata sejecha, hazvisi nyore kubvisa kupfeka.

Mushure mekupfurwa peening (jecha blasting) kurapwa, pamusoro pesimbi inenge yakaoma sesandpaper, zvinova ndizvo zvatinowanzodaidza kuti kukwasharara kwepasi.

Zvinhu zvinokuvadza zvisingaoneki nemaziso

Munguva yekugadziriswa kwepamusoro kwesimbi ine ngura isati yapendwa, zvikamu zvinoratidzira makomba ekuora mushure mekuputika kwepfuti (kunyanya pasi pemakomba ekuora) anogona kunge ane munyu unonyungudika.Dry shot blasting haigoni kubvisa munyu uyu.Naizvozvo, usati wapenda, zviri nani kutarisa kana paine soluble munyu uye kutarisisa kwavo pane workpiece pamusoro neanokosha munda test chiridzwa.Kana kuwanda kwemunyu unonyungudika kuchidarika kukosha kunobvumirwa, matanho achatorwa kuti abvise.

Kuchenesa giredhi

Economy idambudziko ratinofanirwa kufunga nezve padanho rekuchenesa pamusoro.Kazhinji kutaura, kukwirisa zvinodiwa nehutsanana, kunowedzerawo mutengo wekuchenesa.Pakucheneswa kwesimbi pamusoro, zvinodiwa zvehutsanana zvechikamu chekuchenesa zvakanyanya (SA 3) zvinodhura kupfuura izvo zveasina kunyatso kuchenesa level (SA 2).Kucheneswa kwepamusoro kwezvivakwa zvesimbi zvinoshandiswa munzvimbo inoodza zvakanyanya zvinoda kusvika padanho repamusoro, asi mune dzimwe nguva, kudhura-kushanda kwehupenyu hwebasa rekuputira chinhu chakakoshawo pakusarudzwa kwedanho rekuchenesa.

Iyo workpiece inobatwa neasina-metallic abrasive haina Fe atomu zvakasara uye haisi nyore kuita ngura uye discolor, asi ine yakakwirira yekupwanya mwero, huru huru uye kusvibiswa kwakakomba, iyo isingaenderane nezvinodiwa zvekuchengetedzwa kwezvakatipoteredza.TAAgrit yesimbi isina tsvina anogona kugadzirisa matambudziko anowanikwa.Mune imwe nzvimbo yekuchenesa, iyo workpiece inodiwa kwete chete kuti irege kubva pakuora uye kusvibiswa mushure mekugadziriswa kwepamusoro, asiwo kugadzira imwe roughness pamusoro pepamusoro uye kuwana kukwana kwakakwana mushure mekuputira.

Thesimbigritmade ofhigh carbon steel shotinogona kusangana nehutsinye hunodiwa mushure mekuchenesa, asi maatomu eFe acharamba ari pamusoro, zvichikonzera ngura uye kushanduka uye kukanganisa kunaka kwekuputira.

Stainless simbi yakachekwa wayainogona kudzivirira workpiece pamusoro kubva ngura uye discoloration, asi ichava denderedzwa panguva kuputika, saka haigoni kusangana roughness zvinodiwa.

Stainless simbi grit is Stainless material grit particle, haigoni kungogadzirisa dambudziko rekuora uye kushanduka kwemavara nekuda kweatomu eFe asara, asiwo kugadzira mipendero nemakona kuti iite kudzika kweanchor inodiwa, kuvandudza kunaka kwekuputira uye kusangana nezvinodiwa zvekuputira.Iine tarisiro yemusika wakafara.

Pamusoro pe, simbi isina nguragritinogona kutsiva akasiyana-siyana emaminerari jecha uye asiri-metallic abrasives, akadai sealumina oxide, emery, jecha requartz, girazi mabheji, nezvimwe.

Kuenzaniswa neasiri-metallic abrasives,simbi isina nguragrit inogona kuunza mutengo wakaderera wekushanda, kuderedza zvakanyanya kuburitsa guruva, kuderedza mutengo wekubvisa guruva uye kugadzirisa nharaunda yekushanda.

Kushandiswa kwesimbi isina simbi grit:
