Kubvisa ngura: nzira

Ngura echitema ndivo kupfuura kuramba uye kuvabvisa pane chete. Mumwe aifanira kuzviita, ziva kuti ngura kubviswa pasina chinokosha zvishandiso - wakaoma chaizvo basa, uye nzira kuti achinatsa zvokunyama kunoenderana ya ngura.

Today akaita nhamba dzakasiyana zvinoreva kuti kubvisa Dombo iri, asi vanofanira kushandiswa nokungwarira, nekuti vazhinji vacho nehasha, uye akaumbwa rokuchenesa nevasori, abrasives kana acids. Nokudaro hukawanika siyana vane nzira dzavo pachavo uye zvinoreva kuti kubvisa ngura echitema.

Kubvisa ngura kubva simbi

Operation kuti kubviswa ngura nesimbi hukawanika vanofanira kutanga pakarepo pamusoro vasabatwa worudzi ruduku kuonekwa. Pakutanga excretion zvinoberekwa kushandisa simbi mumakwenzi kana sandpaper. Unogona kuedza rinokosha mhando mhinduro ngura convert. Nokuti chinangwa ichi, kusazvibata fibers kubvisa, kubata pemvura pamwe solvent kana benzine kuti degreasing, uye ipapo kushandisa transducer kuti simbi. The pemvura ruvara zvishoma nezvishoma kuva rinokwanisa kucheneruka kana pepuru. Kushanda zvinogadzirisa zvakadaro, unofanira kutora matanho okudzivirira, shandisa dziviriro, uye kana iine acid kuonana ganda, pakarepo kusuka nemvura.

Kubviswa ngura kunogona kuitwa nemunhu nzira electrochemical. Nokuti chidimbu ichi wanamatira zvesimbi zingi, ndipo zvose mumvura, acidified pamwe sulfuric acid. Pashure pemaawa mashomanana nengura anofanira kuenda. Pashure paizvozvo chigadzirwa anofanira kusuka nokuoma.

Kurumidza kubvisa ngura nokushandisa mugaba chloride mhinduro, umo maminitsi akawanda aiitirwa chakaremara pamusoro, uye ipapo nemvura inodziya uye waoma. Also berekai ngura kubviswa pakati orthophosphoric acid, iro rinoshandiswa sezvo convert.

Nokuti simbi kubva tsvuku Dombo yokunatswa pacho rinoshandiswa mafuta hove. Nzira aishanda kwemaawa maviri chiine layer pashure iyo ngura kure. Uyezve, mafuta hove unoumba rwokudzivirira firimu iyo chinonditadzisa mamwe oxidation.

Kubvisa ngura kubva mbatya

Kugura echitema kubva zvipfeko zvakaoma chaizvo, nokuti anodya mumba oxides nokusanzwira nyore kuchenesa. Kudzorera yepakutanga chitarisiko rejira, unogona kushandisa ndimu muto. Nokuti chinangwa ichi, mumwe bande kuti ndimu riri akaputirwa gauze, rinoshandisirwa simbi, uye ipapo ironed. jira Light anogona kuedza kugadzirisa rehydrogen peroxide.

Dzichibvisa ngura uye kubereka tichibatsirwa vhiniga. Kuti aite izvi girazi remvura rakasanganiswa spoon maviri neshungu vhiniga. Jira aine kubata dzichinyikwa ichi mhinduro uye kubvumirwa kumira maminitsi akawanda uye ipapo wosukurudzwa rakasanganiswa amoniya. Wechitema jira anatswa kubva musanganiswa chena nengura choko uye glycerol vanobviswa zvienzane nhengo. Slurry rinofanira kuiswa pamusoro gwapa uye ipapo kusiya pazuva mushure chinhu ari kumboshamba akandoshamba.

Kubvisa ngura kubva pombi dzemvura

Kuti tidzivise nechitarisiko ngura echitema pamusoro chimbuzi, kuchimbuzi kana kicheni singi, pavaizoramba munofanira kutevera kuti pemvura yaiva sezvo shoma mvura sezvinobvira. Kuchangotanga kuratidzwa ngura rokutsvaira vanofanira kubereka nyaya zvimwe oxides zvinopfuura enamel uye zvinoparadza. Ngura Kubviswa rinoitwa kushandisa kudziyirwa vhiniga pamwe patafura munyu, mafuta hydrogen peroxide uye amoniya (1 kusvika 10), ndokunatsawo pasoda mhinduro.

Abrasives (upfu, munyu, kubika pasoda) anechekuita pamusoro enameled pamusoro chete kuburikidza nyoro shaya, uye nokuda dzavo acrylic anogona kushandiswa. Kuchenesa inokurudzirwa kutora mvura Formulations - vhiniga, ndimu muto kana sipo. Zvisinei, ngura, zvakasimba midzi muna singi kana mubhavha, zvisingaiti kuchenesa, nyore chete kunyora pamusoro payo.
