Kusimuka kwemasimba makuru epasi rose kunotanga kubva mukuvaka ngarava uye kuenda nemunyanza.Sechiratidzo chakakosha chechikamu cheindasitiri yenyika,indasitiri yekuvaka ngarava, se "korona yemaindasitiri akazara", ine yakakwira dhigirii yekuwedzera kwemaindasitiri uye yakasimba maindasitiri drive.Kubva muhafu yekutanga yegore rino, kushomeka kwehuwandu hwekutakura pasi rose kwakonzera kukwira kwemitengo yekutumira, uye kukura kwekuda kwekutakura kwakakonzera kuwedzera kwemirairo mitsva yengarava, kubereka "nzvimbo yakabudirira isingaonekwe mukati. makore gumi” muindasitiri yepasi rose yekuvaka ngarava.zvakanaka.
Kunyangwe mamiriro ezvinhu akanaka, indasitiri yekuvaka ngarava ichiri kufanira kutarisana nematambudziko mazhinji ekusimudzira maindasitiri pasi pekumanikidzwa kukuru kwekuchengetedzwa kwezvakatipoteredza.Mumakore achangopfuura, International Maritime Organisation (IMO) yakawedzera zvishoma nezvishoma mutemo wayo wekuchengetedza kwezvakatipoteredza, uye yakakodzera simba remagetsi uye kabhoni intensity zviratidzo zvakagadzira zvakajeka nguva yekupinda musimba.
Panguva imwecheteyo, chinangwa che "carbon peak uye kabhoni kusarerekera" chakakurudzirwawo kusimudzira kwakasvibira kweindasitiri yekuvaka ngarava.Nezvitsva zvinodiwa, "decarbonization" yakakosha, uye kushandiswa kwakadzama kwesimba idzva, zvinhu zvitsva uye mamwe egirinhi uye akangwara matekinoroji azova kutungamira kwakakosha kweindasitiri yekuvaka ngarava nekugadzirisa uye yekutumira mune ramangwana.
Sechinyakare, kudonha kwengarava chikamu chakakosha chekugadzirisa nekugadzirisa ngarava.Kare, yainyanya kuitwa nenyundo yefoshoro yemaoko kana kuputika kwemhepo.Nekudaro, ikozvino mumabhizinesi makuru ekuvaka ngarava, kuwedzera uye kuwedzera laser kuchenesa kunoshandiswa kuita kuchenesa ngarava.Kuchenesa, nei kune kuchinja kwakadaro?Kana kuti ndezvipi zvakanakiraLaser yekuchenesa michinazvichienzaniswa nemaitiro ekuchenesa nzira?
Tsika yekuchenesa maitiro mukuvaka ngarava nekugadzirisa
Mukuvaka nekugadzirisa ngarava, kune nhamba huru yekuchenesa zvinongedzo, kunyanya kusanganisira simbi ndiro pretreatment (tisati tasveta uye mushure mekugadzira) uye segmental pretreatment (kusati kwapenda) kwezvikepe zvitsva, pamwe nekubvisa ngura uye kubvisa zvachose mukugadzirisa nekugadzirisa kwezvikepe zvekare.Pendi uye yechipiri pendi kugadzirisa.
Kucheneswa kwechinyakare nekubvisa pendi maitiro anonyanya kusanganisira kugaya nemaoko, kuputika kwejecha, kuputika kwepfuti, kugeza kwemvura kwakanyanyisa uye kuchenesa makemikari.Aya echinyakare ekuchenesa maitiro anogona kuzadzisa zvinodikanwa zvekuchenesa hull maererano nekugona uye nekubvisa ngura mhando, asi haigone kufuratirwa.Hongu, iwo anowanzo shanda zvakanyanya, kushandiswa kwemvura yakakwira uye magetsi, kunyanya kuputika kwejecha kunounza huwandu hukuru hwehutsi neguruva, zvichikonzera kusvibiswa kwakakomba kune zvakatipoteredza, pamwe nekurasa kudzokororwa kwemvura mushure mekushambidzika kwemvura, uye mamwe mabasa zvinodiwa zvehutsanana hwepamusoro hazvigone kupedzwa nezvimwe.
Laser yekuchenesa tekinorojiine zvakawanda zvakanaka zvakadai sehapana kukanganisa kune substrate, kunyatso kudzora pachiyero chemicron, kuchengetedza simba uye kuchengetedza kwezvakatipoteredza, saka yave nzvimbo yekutsvaga mukuvaka ngarava.
1. Manual ngura kubvisa
Zvishandiso zvekubvisa ngura nemaoko zvinosanganisira sando, mafoshoro, mapanga esimbi, mabhurasho ewaya, nezvimwewo. Kazhinji, ngura dzakakora dzinodonhedzwa nesando dzozobviswa nefoshoro.High labor intensity uye yakaderera ngura kubvisa kunyatsoshanda.
2. Mechanical ngura kubvisa
(1) Diki pneumatic kana yemagetsi kubvisa ngura;(2) pfuti peening (jecha) kubvisa ngura;
(3) Derusting by high pressure water abrasive;(4) Kuparadza nekuputika kwepfuti.
3. Kemikari kubvisa ngura
Inonyanya kuita ngura kubvisa nzira inoshandisa kemikari inopindirana pakati peasidhi nesimbi oxides kuti ibvise ngura pamusoro pesimbi, kureva, iyo inonzi pickling uye kubvisa tsvina, inogona kushandiswa chete mumusangano.Kemikari kubvisa ngura kune njodzi yakanyanya, kusvibiswa kwezvakatipoteredza, uye inorambidzwa kushandiswa.
4. Laser ngura kubviswa
Laser rust kubviswa ihwo hutsva hwakasvibirira, hushamwari hwezvakatipoteredza, hunobudirira uye hwakachengeteka hutsva tekinoroji, iyo ichakurumidza kutsiva maitiro ari pamusoro uye kushandiswa zvakanyanya.Kunyanya mukubvisa pendi, kubviswa kweoiri, kuchenesa mupendero uye kubvisa ngura, uye kubvisa oxide layer, kuchenesa laser kuchaita basa risingadzokerike.
Zvichibva pane chokwadi chiri pamusoro, pasi pezvinodiwa zveEIA mitsva, mabhizinesi eindasitiri yekuvaka ngarava anofanirwa kutsvaga nzira nyowani, dzinoshanda uye dzakachena dzekuchenesa uye nzira dzekugadzirisa marwadzo eindasitiri.
Laser kuchenesa kunoita kuti ngarava kuchenesa sarudzo yakakosha
Mumakore achangopfuura, pasi pekukurudzira kwekushanda kwepamusoro, kuchengetedza simba uye kuchengetedza kwezvakatipoteredza kusimudzira kusimukira kweindasitiri, tekinoroji yekuchenesa laser yakabuda zvishoma nezvishoma mumashandisirwo epamusoro-soro senge mota nyowani dzemagetsi, aerospace, uye precision zvemagetsi, uye zvakare. yakaratidza kuwedzera uye kuwedzera kugona kwekushandisa muindasitiri yekuvaka ngarava.
Laser yekuchenesa tekinoroji ine akawanda mabhenefiti akadai sekusava nekukuvadzwa kune substrate, kunyatso kudzora padanho remicron, kuchengetedza simba uye kuchengetedza kwezvakatipoteredza, nezvimwewo, uye inogona kuzadzisa zvizere zvinodiwa zvekubvisa ngura kweese maprofiles esimbi uye pretreatment isati yasvika uye mushure mekugadzira.
Panyaya yekugadzirisa ngarava, kuchenesa laser, se "high-precision" yekuchenesa tekinoroji, yakakodzera kupenengura ngura uye pendi pamusoro pemakabati, matangi eballast, matangi emafuta, nezvimwewo, pamwe nekucheneswa kwekabhoni. madhipoziti akadai semarine dizeli injini cylinder mavharuvhu Izvo hazvikuvadzi substrate, uye inogona kutarisana nediki diki pasina zvipingamupinyi zvekunyatsobvisa chiyero, yakakwirira yekuchenesa mhando, kuchengetedza simba uye kuchengetedzwa kwezvakatipoteredza.
Kana iwe uchida kudzidza zvakawanda nezve laser yekuchenesa, kana uchida kukutengera yakanakisa laser yekuchenesa muchina, ndapota siya meseji pane yedu webhusaiti uye titumire email zvakananga!
