Tarisa-tarisa. Mabhiriji aunoyambuka, magwenya emagetsi anovhenekesa imba yako, ngarava dzinotakura zvinhu kuburikidza nemakungwa, uye mapaipi anogadzira mafuta mumaindasitiri edu—zvivakwa zvikuru izvi zvine muvengi akanyarara, asingaregi. Uye zita razvo ingura. Asi kune muvengi wese ane simba, pane dziviriro yakasimba. Dziviriro iyoyo isayenzi yehunyanzvi hwemaindasitiri yekudzivirira ngura uye pendi yekudzivirira ngura.
Zvinopfuura kungova ruvara chete, machira aya masisitimu akagadzirwa zvakanaka, anoshanda senhoo isingaoneki inochengetedza kuvimbika uye kugara kwenguva refu kwezvinhu zvinotsamira panyika yedu yanhasi.
Kunzwisisa Kuora uye Ngura
Kuora inzira yechisikigo yemagetsi apo simbi yakanatswa—yakadai sesimbi, musimboti wezvivakwa zvemazuva ano—inodzokera kuchimiro chakasimba chemakemikari, se oxide yayo. Chaizvoizvo ndiko kuedza kwesimbi kudzokera kumamiriro ayo ekutanga muvhu.
Ngura ndiro zita rinowanzo shandiswa pakuora kwesimbi nesimbi dzayo, zvichikonzera ma oxides ane ruvara rwetsvuku-orenji. Hunyoro uhwu hunongotanga kuita kuti iron itange.
Kumhanya kwekurwisa uku kunokurumidziswa nezvinhu zvakati wandei:
Nzvimbo dzeMugungwa: Munyu ielectrolyte yakanaka kwazvo, zvichiita kuti mapuratifomu egungwa, ngarava, uye zvivakwa zvemahombekombe zvive nyore kudzivirirwa.
Mhepo dzeMaindasitiri: Zvirimwa zvemakemikari zvinoburitsa maasidhi, sarufa, nezvimwe zvinosvibisa zvinodya simbi zvakanyanya.
Kugara kwehunyoro nekupisa: Hunyoro hunogara huripo uye kuwedzera/kukwenya kubva pakuchinja kwekupisa zvinoisa simbi itsva panjodzi.
Migumisiro yekuora kusina kugadziriswa yakaipa: kutadza kushanda zvakanaka kwechivako, njodzi dzinoparadza dzezvakatipoteredza dzinobva mumidziyo inodonhedza mvura, nguva yekushanda isina kurongwa, uye mari yekugadzirisa zvinhu zvisina kurongeka. Ndokusaka sisitimu yekudzivirira isiri kungofunga nezverunako chete; inyaya yekudzivirira yakakosha uye yakakosha.
Kudzivirira Kwakawanda: Kubvisa Sisitimu Yekuputira
1. Kutanga:
Iyo primer ndiyo inonyanya kukosha, sezvo ichiiswa zvakananga pamusoro pesimbi yakagadzirwa. Mabasa ayo haakurukuriranwe:
Kunamira: Inofanira kuumba chisungo chisingaputsike nesimbi.
Kudzivirira Kuora: Ma primer mazhinji ane pigments dzinoshanda dzakadai se zinc phosphate kana dzimwe nzira dzisina chepfu dzinodzivirira ngura pamusoro pesimbi nemakemikari.
Kudzivirira Cathodic: MaPrimer ane Zinc-Rich anotora danho rinotevera. Zvidimbu zvezinc zviri mujira hazvina simba rekuita kuti simbi ishande zvakanaka. Izvi zvinoreva kuti zinc ichaora *panzvimbo* yesimbi, zvichipa dziviriro yakasimba kunyangwe jira racho rakakuvara zvishoma.
2. Nguo Yepakati:
Rutivi urwu, runowanzova epoxy ine kuvakwa kwakawanda, runoshanda sebasa guru rehurongwa. Mabasa aro makuru ndeaya:
Dziviriro Yezvipingamupinyi: Inowedzera ukobvu hwefirimu zvakanyanya, zvichiita kuti ive nhoo yakasimba, isingapindi mvura inovhara hunyoro, okisijeni, uye makemikari anopinda.
Kugara kwenguva refu: Inowedzera kukweshwa kwakanyanya uye kuramba kubatwa, ichidzivirira primer kubva mukukuvadzwa kwemuchina.
Kuvaka: Inogadzira nzvimbo yakafanana, ichivhara chero zvikanganiso zvidiki uye ichipa substrate yakakwana ye topcoat.
3. Koti repamusoro:
Topcoat ndiyo jira rinotarisa nyika yekunze. Kunyange zvazvo richipa ruvara rwekupedzisira uye runako, mabasa aro ehunyanzvi akakosha:
Kuramba Mamiriro Ekunze: Yakagadzirwa kuti irambe kuora kubva mumwaranzi yeUV, kudzivirira kudonha kwechoko, kurasikirwa nechiedza, uye kuputika kwefirimu.
Kuramba Kushanda Kwemakemikari Uye Kupera Kwemvura: Inodzinga makemikari chaiwo uye inochengetedza ruvara rwayo munzvimbo dzakaoma.
Kuchena uye Kuchengetedza Kupenya: Munzvimbo dzakawanda, nzvimbo ine mwenje wakareba uye uri nyore kuchenesa inokosha pakuchenesa uye kupenya kwechiedza.
Mhando dzeMapurasitiki ekugadzira
Kusarudza pendi yakakodzera zvichienderana nenzvimbo, substrate, uye zvinodiwa pakushanda kwayo.
Kuputira kweEpoxy:Ibasa guru muindasitiri. Vanozivikanwa nekunamatira kwavo kwakanaka, kuomarara, uye kuramba kwavo kusingawirirani nemakemikari, zvinonyungudutsa, uye hunyoro. Kusasimba kwavo kusasimba kweUV, izvo zvinokonzera kudonha kwechoko uye kuora.
Kupfeka kwePolyurethane:Mambo we topcoats. Aliphatic polyurethanes inopa kupenya kwakanaka uye kuchengetedza ruvara, kunyangwe kana yakasvikwa neUV kwenguva refu. Inodzivirirawo kukweshwa uye makemikari, zvichiita kuti ive mugumo wakakwana wemabhiriji, michina yeindasitiri, uye simbi yekuvaka.
MaPrimer Akapfuma neZinc (ZRPs):Dziviriro huru yesimbi munzvimbo dzinopisa. Inowanikwa se epoxy (organic) kana silicate (inorganic), ZRPs dzinopa dziviriro ye cathodic. Inorganic zinc silicates dzakasimba zvikuru uye hadzipiswi nekupisa, zvichiita kuti dzive dzakakodzera ngarava, zvivakwa zvekunze, uye zvirimwa zve petrochemical.
Mapeti eAlkyd:Pendi dzechinyakare, dzakagadzirwa nemafuta dziri nyore kushandisa uye dzinodhura zvishoma munzvimbo dzisina kusimba, dzemukati, kana dzekumaruwa. Dzinogara kwenguva refu uye hadzina simba remakemikari.
Kuputira Fluoropolymer (PVDF):Inopa mwero wepamusoro wekudzivirira UV uye mamiriro ekunze, inoshandiswa pazvivakwa zvine mukurumbira uko kugadzikana kwemavara kwenguva refu ndiko kunonyanya kukosha.
Kupenda kwakakwirira kupfuura mamwe ose pasi rose kunokundikana kana kukaiswa panzvimbo isina kugadzirwa zvakanaka. Mutemo wegoridhe weindasitiri ndewekuti kushanda kwesystem yekupenda kunoenderana ne49% pakugadzirwa kwenzvimbo uye 51% pakupenda kwayo pachayo.
Nzira huru ndeyekuputika nehasha. Maitiro aya anoita zvinhu zviviri zvakakosha: kubvisa tsvina yese: ngura, chikero chemugayo, munyu, mafuta, uye pendi yekare, zvichiita kuti pamusoro payo pave pakachena zvakakwana.
Inogadzira chimiro chepamusoro kana kuti "anchor pattern," kukweshana kwakadzorwa kunowedzera zvakanyanya nzvimbo yepamusoro kuti primer ibate pairi nemakanika.
Mhedziso:
Sisitimu yekuputira yakagadzirwa nemazvo uye yakashandiswa zvakanaka inobhadhara yakawanda kupfuura:
Kuwedzera Hupenyu hweBasa kubva pamakore kusvika kumakumi emakore.
Kuderedza zvakanyanya mari yekugadzirisa nekugadzirisa zvinhu nekukurumidza.
Kuve nechokwadi chekuchengetedzwa kwekushanda uye kudzivirira kukundikana kwakaipisisa.
Kuwedzera Uptime uye kushanda zvakanaka.
