Chinangwa chekubatanidza mapango emwenje

Mumhepo, zinc inodzivirira ngura zvakanyanya kupfuura simbi; mumamiriro ezvinhu akajairwa, dzinc inodzivirira ngura zvakapetwa makumi maviri neshanu pane simbi. Kuputira zinc pamusoro pedanda remwenjeinoidzivirira kubva muzvinhu zvinoparadza. Kuisa simbi mu "hot-dip galvanizing" pari zvino ndiyo inonyanya kushanda, inoshanda, uye inodhura mari yekudzivirira simbi kubva mukuora kwemhepo pasi rese. Tianxiang inoshandisa tekinoroji yepamusoro ye "zinc-based alloy hot-dip galvanizing", uye zvigadzirwa zvayo zvakaongororwa neTechnical Supervision Bureau uye zvemhando yepamusoro.

Chinangwa chekugadzira magaroni ndechekudzivirira ngura yezvikamu zvesimbi, kuvandudza kuramba ngura uye hupenyu hwebasa resimbi, uye zvakare kuwedzera chitarisiko chekushongedza kwechigadzirwa. Simbi inotsungirira nekufamba kwenguva uye inoora kana yaiswa mumvura kana muvhu. Kugadzira magaroni anopisa kunowanzo shandiswa kudzivirira simbi kana zvikamu zvayo kubva mukukuvadzwa.

Kunyange zvazvo zinc isingachinji nyore nyore mumhepo yakaoma, zinc carbonate yakawanda inoumba firimu rakatetepa munzvimbo dzine hunyoro. Firimu iyi inodzivirira zvikamu zvemukati kubva mukuora nekukuvadzwa. Kunyangwe zvimwe zvinhu zvikaita kuti zinc layer iparare, zinc yakakuvara inogona, nekufamba kwenguva, kuumba micro-cell composite musimbi, ichishanda se cathode uye ichidzivirirwa. Hunhu hwe galvanizing hwakapfupikiswa seizvi:

1. Kudzivirira ngura kwakanyanya; zinc coating yacho yakanaka uye yakafanana, haikanganisike nyore, uye inobvumira magasi kana zvinwiwa kupinda mukati mechinhu chebasa.

2. Nekuda kwe zinc layer yakachena, haikanganisike nyore nyore munzvimbo dzine acidic kana alkaline, zvichidzivirira simbi kwenguva yakareba.

3. Mushure mekunge chromic acid yaiswa, vatengi vanogona kusarudza ruvara rwavanoda, zvichiita kuti ruve rwakanaka uye rune runako.

4. Tekinoroji yekuvhara zinc ine ductility yakanaka, uye haizobviswi nyore nyore panguva yekukombama, kubata, kana kurovera kwakasiyana-siyana.

Ungasarudza sei mapango emwenje akavharidzirwa?

1. Kuisa galvanizing inopisa (hot-dip galvanizing) kwakanaka kupfuura kuisira galvanizing inotonhora, zvichiita kuti jira rirambe rakakora uye rinodzivirira ngura rive rakawanda.

2. Matanda emwenje akagadzikwa anoda bvunzo yekuenzana kwe zinc coating. Mushure mekunyudzwa kashanu kakatevedzana mumushonga we copper sulfate, muenzaniso wepombi yesimbi haufanirwe kutsvuka (kureva kuti, hapana ruvara rwemhangura runofanira kuoneka). Uyezve, pamusoro pepombi yesimbi yakagadzikwa inofanira kuvharwa zvachose ne zinc coating, pasina mavara matema kana mabhurumu asina kuputirwa.

3. Ukobvu hwezinc coating hunofanira kunge hwakakura kupfuura 80µm.

4. Ukobvu hwemadziro chinhu chakakosha chinokanganisa mashandiro uye hupenyu hwepaburi remwenje, uye kutevedzera mitemo yenyika kwakakosha pakuona kuti chigadzirwa chakanaka. Kuti tikubatsire kusarudza zviri nani, tinokupa fomura yekuverenga huremu hwepaburi remwenje: [(dhayamita yekunze - ukobvu hwemadziro) × ukobvu hwemadziro] × 0.02466 = kg/mita, zvichikubvumidza kuverenga huremu hwepaburi resimbi nemazvo zvichienderana nezvaunoda chaizvo.

Tianxiang inyanzvi mukutengesa zvinhu zvakawandamapango emwenje akavharidzirwa. Tinoshandisa simbi yemhando yepamusoro yeQ235/Q355 sechinhu chedu chikuru, tichishandisa tekinoroji yekupisa-dip galvanizing. Ukobvu hwezinc coating hunoenderana nezvinodiwa, hunodzivirira ngura, hunodzivirira mhepo, uye hunodzivirira mamiriro ekunze zvakanyanya, huchigara kwenguva inodarika makore makumi maviri. Tine hunyanzvi hwakakwana, tinotsigira kugadzirisa zvinhu zvakawanda, uye tinopa mitengo yepamusoro yekutenga zvinhu zvakawanda. Tinopa vimbiso yakakwana yemhando yepamusoro uye kutumirwa kwezvinhu nenguva. Tinokugamuchirai kuti mutibate!
