Chemical Surface Kugadzirira

Kunyanya kushandiswa kunoenderana zvakanyanya nechimiro chepamusoro chiri kucheneswa uye chimiro chekusvibiswa. Nzvimbo zhinji dzehupfu dzakaputirwa mushure mekuchenesa ingave simbi, simbi, kana aluminiyamu. Sezvo isiri yese yemakemikari-mhando yekugadzirira inoshanda kune zvese izvi zvinhu, iyo nzira yekugadzirira yakasarudzwa zvinoenderana neiyo substrate zvinhu. Pachinhu chimwe nechimwe, mhando yekuchenesa ichakurukurwa uye maitiro ayo akasiyana eiyo substrate achatsanangurwa. Maitiro ekushandisa chaiwo akafanana kune chimwe nechimwe chinhu.

KUCHENZA SIMBA YEMAGARA

Alkaline Vanochenesa

Alkaline cleaners for galvanized steel kazhinji ine musanganiswa wealkaline munyu wakapfava usingakuvadzi nzvimbo ye zinc. Mune zvimwe zviitiko, diki-kusvika-yemwero yakawanda yemahara caustic soda inogona kunge iripo muchenese kubvisa ivhu rakaoma kana kupa etch inodiwa. Aya makuchenesa anogona kuiswa nemagetsi pfapfaidzo, kunyudza, electrocleaning, kana kupukuta nemaoko.

Munzira yekupfapfaidza simba, zvikamu zvinofanirwa kucheneswa zvinorembedzwa mugero apo mhinduro yekuchenesa inopombwa kubva mutangi rekubata uye kupfapfaidzwa, pasi pekumanikidzwa, pazvikamu. Iyo yekuchenesa mhinduro ipapo inoramba ichitenderedzwa. Kupfapfaidza kudzvanywa kunobva pa4 kusvika ku40 psi.

Mune nzira yekunyudza, zvikamu zvinofanirwa kucheneswa zvinongonyudzwa mumushonga wemuchenesi uri musimbi yakapfava kana tangi yesimbi.

Electrocleaning ishanduro yakasarudzika yekunyudza yekuchenesa umo yakananga ikozvino inopfuudzwa nemumhinduro. Zvikamu zvinofanirwa kucheneswa zvakaturikwa mumushonga uye ndiwo anode, nepo mamwe maelectrode anoita secathode. Electrocleaning inoshanda kupfuura kunyudzwa kuri pachena nekuda kwekukwesha kwegasi mabubbles anogadzirwa pamusoro pechikamu.

Nzira yekupukuta nemaoko yekushandiswa inowana rubatsiro rwakawedzerwa kubva kune chiito chemuviri chekubvisa ivhu kubva pamusoro nemucheka kana chipanje, nemuchenesi achibatsira kunyungudutsa ivhu.

Alkaline cleaners inowanzoiswa kune galvanized zinc surfaces mumatanho maviri-iyo yekuchenesa nhanho uye yekusuka mvura nhanho. Nhengo dzinofanirwa kucheneswa dzinowanzofambiswa kubva pane imwe nhanho kuenda kune imwe mushure mekuratidzwa kwakakodzera kugadzira kuchenesa. Mamwe matanho ekuchenesa nekusuka anogona kushandiswa kana zvichidikanwa. Makemikari ari mumabhavhu emhando iyi anowanzo chengetwa patembiricha iri pakati pe80 ne200°F (27 ne93°C). Kazhinji tembiricha i120 kusvika 150°F (49 kusvika 66°C) yekupfapfaidza uye 150°F (66°C) yekunyudzwa. Iyo nguva iyo zvikamu zvinoratidzwa kune aya makemikari iri pakati pemakumi matatu masekonzi uye 30+ maminetsi. Generally, ndeye 1 kusvika 2 maminitsi ekupfapfaidza uye maminetsi maviri kusvika mashanu ekunyudzwa. Kuti zvive zvinobudirira, kuwanda kweiyo alkaline yekuchenesa mhinduro kunofanirwa kunge kuri pakati pe2/5 ne1 odgal (4 kusvika 16 g/L). Kazhinji, mupfapfaidzo, 2/120 kusvika 1 odgal (2 kusvika 1 g/L) uye yekunyudza 4 kusvika 8 odgal (6 kusvika 12 g/L).

Iyo inodhura zvakanyanya yemhando idzi ndeye electrocleaner, nekuda kweiyo yepamusoro yekugezesa yekugeza inoshandiswa uye mutengo wemagetsi kune electrocleaner. Iyo inodhura zvishoma ndeye sprayer yekuchenesa, ine-kupukuta nemaoko pane imwe nzvimbo pakati. Mhando ye alkaline ndiyo, kusvika kure, inonyanya kushanda uye kazhinji inodhura zvakanyanya kushanda. Kuti kuderedzwa kwekuita, nzira dzekushandisa dzaizoita generalInofanirwa kuverengerwa se: kuchenesa magetsi, kuchenesa kupfapfaidza, kunyudza kuchenesa, uye kupukuta nemaoko.

Acid Cleaners

Acid cleaners haiwanzo shandiswa kuchenesa simbi. Pakati peaya maasidhi ekuchenesa anoshandiswa, rudzi rwakajairika rwaizova munyu ane acidic zvinyoro, kwete kunyanya kuodza kune zinc pamusoro. Izvo zvinofanirwa kucherechedzwa, zvisinei, kuti kune akasarudzika asidhi ekuchenesa akagadzirirwa kubvisa chena corrosion chigadzirwa kubva kune galvanized.

Mune nzira yekupfapfaidza yemagetsi yekushandiswa, zvikamu zvinofanirwa kucheneswa zvinomiswa mumugero apo mhinduro yekuchenesa inopombwa kubva mutangi rekubata uye kupfapfaidzwa pasi pekumanikidzwa pazvikamu. Mushonga wekuchenesa unozodonhedzwa zvakare mutangi rekubata uye kutenderera kunodzokororwa. Kupomba, kupfapfaidza, uye kudira mvura kunoitika panguva imwe chete uye nguva dzose.

Kana iyo nzira yekunyudza yekushandiswa inoshandiswa, zvikamu zvinofanirwa kucheneswa zvinongonyudzwa mumushonga wemuchenesi uri musimbi yakapfava kana tangi yesimbi.

Electrocleaning ine acid cleaners ishanduro yakasarudzika yekunyudza yekuchenesa umo yakananga ikozvino inopfuudzwa nemumhinduro. Zvikamu zvinofanira kucheneswa kazhinji anode, nepo mamwe maelectrode anoita secathode. Electrocleaning inowanzo gadzira nzvimbo yakachena kupfuura kunyudzwa kuri pachena nekuda kwekukwesha kwemabhuru eokisijeni ari kubuda pamusoro pechikamu. Iyo okisijeni inokonzerwa ne electrolysis yemvura.

Nzira yekupukuta nemaoko inowana bhenefiti yakawedzerwa kubva murubatsiro rwemichina yekufambisa ivhu kubva pamusoro nemucheka kana chipanje nemuchenesi zvichibatsira kunyungudutsa ivhu.

Acid cleaners inowanzoiswa kune galvanized zinc surfaces mumatanho maviri: nzvimbo yekuchenesa uye yekusuka mvura. Mamwe matanho, kuchenesa nekusuka, zvinogona kushandiswa kana zvichidikanwa. Makemikari ari mubhavhu anochengetwa patembiricha ye80 kusvika 200°F (27 kusvika 93°C);kazhinji 100 kusvika 140°F (38 kusvika 60°C) yekupfapfaidza uye 140 kusvika 180°F (60 kusvika 82°C. C) kunyudzwa. Izvo zvikamu zvinoratidzwa kune chemi?cals kwemasekonzi makumi matatu kusvika kumaminitsi mashanu+; kazhinji maminetsi 30 kusvika 5 ekupfapfaidza uye maminetsi maviri kusvika mashanu ekunyudzwa. Mishonga inochengetwa pachikamu che1/2 kusvika 2 odgal (5 kusvika 1 gL); kazhinji 4/16 kusvika 2 odgal(120 kusvika 1 gL) yekupfapfaidza uye 2 kusvika 1 odgal (4 kusvika 8 g/L) yekunyudzwa.

Kuti kuderedzwa kwekuita, nzira dzekushandisa dzaizoita generalInofanirwa kuverengerwa se: electrocleaning, kupfapfaidza kuchenesa, kunyudza kuchenesa, uye kupukuta-maoko.

Neutral Vanochenesa

A neutral cleaner (sekushandiswa kwesimbi yakabatiswa) inogona kuumbwa nemasurfactants chete, neutral munyu pamwe nema surfactants, kana ma surfactants ane zvimwe organic additives. A neutral cleaner inogona kutsanangurwa sechero muchenesi uyo, mumhinduro, anganyore pakati pe6 ne8 pachiyero chepH.

Nesimba rekupfapfaidza simba, zvikamu zvinofanirwa kucheneswa zvinomiswa mugero apo mhinduro yekuchenesa inopombwa kubva mutangi rekubata uye kupfapfaidzwa, pasi pekumanikidzwa, pazvikamu. Mushonga wekuchenesa unoramba uchitenderedzwa. Kupfapfaidza kudzvanywa kunobva pa4 kusvika ku40 psi.

Mune nzira yekunyudza yekushandiswa, zvikamu zvinofanirwa kucheneswa zvinongonyudzwa mumushonga wemuchenesi uri musimbi yakapfava kana tangi yesimbi.

Zvakare, kupukuta nemaoko kune imwezve bhenefiti kubva kune mechanical aid yekufambisa muviri ivhu kubva pamusoro kuburikidza nemucheka kana chipanje, nemuchenesi achibatsira kunyungudutsa ivhu.

Neutral mishonga yekuchenesa inowanzoiswa nekushandisa zvishoma zvishoma zvezvikamu zviviri: nzvimbo yekuchenesa uye yekusuka mvura. Mamwe matanho, kuchenesa nekusuka, zvinogona kushandiswa kana zvichidikanwa. Mishonga inobatwa pakupisa kwe80 kusvika 200 ° F (26 kusvika 93 ° C); kazhinji 120 kusvika 160°F (49 kusvika 71°C) yekupfapfaidza uye 150 kusvika 180°F (66 kusvika 82°C) yekunyudzwa. Izvo zvikamu zvinoburitswa kwe30 masekonzi kusvika ku5+ maminetsi; kazhinji maminitsi 1 kusvika 2 ekupfapfaidza uye maminetsi maviri kusvika mashanu ekunyudzwa.

Mishonga inobatwa pachikamu che1/4 kusvika 16 odgal (2 kusvika 120 gL); kazhinji 1 kusvika 2 odgal(8 kusvika 16 gL) yekupfapfaidza uye 8 kusvika 14 odgal (60 kusvika 105 g/L) yekunyudzwa. Neutral macleaner haashande semuchenesi wekutanga. Vanonyanya kushandiswa se precleaner.
