Yakatumirwa pa 2018-11-12Dacromet coating, inozivikanwawo se zinc flake coating, ine mukana wekuti iyo yekupedzisira haigone kuwanikwa kana ichienzaniswa neyakajairika electro galvanized uye inopisa dip galvanizing maitiro.Zinc flake coating ine zvinotevera zvakanakira:
#1.Kusaita corrosion resistance
Iyo inodzorwa electrochemical kuchengetedzwa kwezinc, iyo shielding effect ye zinc / aluminium mapepa uye kuzvigadzirisa kwega kwechromate kunoita kuti Dacromet coating inopesana zvikuru nekuora apo Dacromet yekuputira inoedzwa mu neutral salt spray.Zvinotora maawa angangosvika zana kuisa coating 1um, iri nani kanomwe-ka10 pane echinyakare galvanizing kurapwa.Iyo yekusarerekera munyu yekupfapfaidza bvunzo inogona kugara kweanopfuura maawa 1000 (kupfeka nehupamhi hwe8um kana kupfuura), uye imwe yakatokwira, izvi hazvigoneke nemarara uye inopisa dip galvanized layers.
#2.Excellent heat resistance
Sezvo Dakoro-yakavharwa chromic acid polymer isina mvura yekristaro uye nzvimbo yekunyunguduka yealuminium/zinc sheet yakakwira, iyo yekupfeka ine yakanakisa-yepamusoro-tembiricha yekudzivirira ngura.Dacromet coating ine kupisa kwekudzivirira kupisa kwe 300 ° C. Inogona kushandiswa nguva dzose kwenguva yakareba pa 250 ° C. Kurwisana kwayo kwekuora kunenge kusingagadziriswi, uye firimu ye passivation pamusoro pe electroplated zinc layer inoparadzwa kumativi ose. 70 ° C, uye kushorwa kwekuora kuderera kwakanyanya.
#3.Hapana hydrogen brittleness
Munguva yehunyanzvi hwekurapa kweDacromet, hapana kugezwa kweasidhi, electrodeposition, electric de-oiling, nezvimwewo, uye hapana electrochemical reaction yehydrogen evolution inokonzerwa neiyo electro-galvanizing process, saka izvo zvinhu hazvizokonzerese hydrogen embrittlement.Saka inonyanya kukodzera kubata elastic parts uye high-simba workpieces.
#4.The goodrecoatability
Kuonekwa kweDacromet coating is silver-grey nekunamatira kwakanaka kune substrate uye zvakasiyana-siyana zvekupfeka.Inogona kushandiswa sechinhu chepamusoro kana seprimer yezvipfeko zvakasiyana-siyana.Electrochemical reactions inoitika pakati pesimbi nekuda kwekugona kusiyanisa.Kune galvanized layers, ese ari iron-based uye aluminum-based layers anopokana ne electrochemically uye anoderedza zvakanyanya kusagadzikana kwekuora.Kune Dacromet anti-corrosion layer, sezvo iyo anti-corrosion yakavakirwa pane chromic acid passivation uye inodzorwa chibayiro chekuchengetedzwa kwescaly zinc layer, hapana electrochemical corrosion inogadzirwa, saka kudyiwa kweZn kunenge kudzvanywa corrosion yeAl inodzvinyirirwa.
#5.Excellent permeability
Iyo Dacromet yekurapa fluid inogona kupinda mukati memubatanidzwa wakasimba weiyo workpiece kuumba ngura-proof coating.Kana iyo nzira ye electroplating yakashandiswa, mukati memukati memutezo wetubular hauna kuputirwa nekuda kwekudzivirira.Nekudaro, nekuti kurapwa kweDacromet kunoshandiswa nekuputira uye kune yakanaka kupinza, inogona kushandiswa kuvandudza ngura yekudzivirira kugona mukati nekunze.
#6.Hapana kusvibiswa
Kana electroplating zinc, pane dambudziko rekuyerera kwetsvina ine zinc, alkali, chromic acid, nezvimwewo, izvo zvinokonzeresa kusvibiswa kukuru.Tembiricha yekupisa dip zinc yakakwira, uye yakaburitswa zinc mhute neHCL zvinokuvadza hutano hwevanhu.Mazhinji emazuva ano kupisa zinc kugadzirwa kunofanirwa kuitirwa kure kubva kumadhorobha nekumaruwa.Iyo Dacromet process yakagadzira munda mutsva wesimbi corrosion dziviriro.Nokuti Dacromet kurapwa inzira yakavharwa, zvinhu zvinoputika panguva yekubikira zvakanyanya mvura, hazvina zvimwe zvinokuvadza zvinodzorwa, uye hazvina kusvibiswa kune zvakatipoteredza.
Kuti udzidze zvakawanda nezve zinc flake coating, ndapota teerera kune yedu webhusaiti: www.junhetec.com
