Paki imwe chete ine 96% zinc mufirimu rakaoma, imwe nzira anti corrosion performance kune inopisa dip.
Tsanangudzo
ZINDN ipaki rimwechete rinonamisa coating iro rine 96% zinc huruva mufirimu rakaoma uye inopa zvese cathodic uye zvipingamupinyi zvinodzivirira zvesimbi.
Inogona kushandiswa kwete chete yakasarudzika sisitimu yekuve imwe anticorrosion performance kune inopisa-dip galvanizing, asi seprimer mune duplex system kana matatu-layer ZINDN coating system.
Inogona kuiswa nekupfapfaidza, kubhurasha kana kukunguruka pane yakachena uye yakaoma simbi substrate munzvimbo dzakasiyana siyana dzemuchadenga.
Cathodic kudzivirira
Mukuora kwe electrochemical, zinc yesimbi nesimbi zvinosangana, uye zingi ine yakaderera electrode simba rinoshandiswa seanode, iyo inoramba ichirasa maerekitironi uye yakasvibiswa, ndiko kuti, chibayiro anode;nepo simbi pachayo inoshandiswa se cathode, iyo inongotamisa maerekitironi uye isingashanduki pachayo, saka inodzivirirwa.
Iyo zinc yemukati muZINDN galvanizing layer inopfuura 95%, uye kuchena kweguruva rinoshandiswa rinosvika 99.995%.Kunyangwe iyo galvanizing layer yakakuvadzwa zvishoma, simbi iri pasi pezinc layer haingaite ngura kusvikira zinc yapedzwa zvachose, uye panguva iyi, inogona kudzivirira kupararira kwemarara.
Barrier protection
Iyo yakakosha kuita meshini inoita kuti ZINDN galvanizing layer inogona kuwedzera kuzvivharira nekufamba kwenguva mushure mekushandisa, kugadzira chivharo chakaomarara, kunyatso patsanura ngura zvinhu, uye kuvandudza zvakanyanya anti-corrosion kugona.
ZINDN inosanganisa hunhu hweaviri ekudzivirira ngura kuita imwe, ichityora muganho wepigment-base reshiyo yeakajairwa majasi, uye kuwana yakanakisa yenguva refu-yekudzivirira-kuora kugona.
95% zinc guruva muZINDN galvanizing layer yakaoma firimu, iyo corrosion current density yakakwira zvakanyanya kupfuura yeiyo zinc-rich coating.
Nekuwedzera kweguruva rezinc mune yakaoma firimu layer, iyo corrosion current density ichawedzera zvakanyanya, uye electrochemical anti-corrosion kugona kuchawedzerawo zvakanyanya.
Zvakanakira ZINDN
Yenguva refu inorwisa-corrosion
Active + Passive dual dziviriro zvivakwa, munyu pfapfaidzo bvunzo inosvika maawa 4500, kuwana nyore kusvika kumakore makumi maviri neshanu (25+ makore anticorrosion life span).
Kunamatira kwakasimba
Iyo yakagadziridzwa fusion agent tekinoroji yakagadzirisa zvizere dambudziko rekunamatira repamusoro zinc huruva (> 95%) mufirimu rakaoma.4% chidimbu chechikamu chemusanganiswa wemusanganiswa chinogona kusungirira zvakasimba ka24 huremu hwayo hwezinc huruva uye kuita kuti ibatane ne substrate uye kunamatira kusvika ku5Mpa-10Mpa.
Kugarisana kwakanaka
ZINDN inogona kushandiswa sechinhu chimwe chete kana semaviri kana matatu-layer system ine ZD sealer, topcoat, silver zinc, nezvimwewo, kuzadzisa zvinodiwa nevatengi zvekugara kwenguva refu uye kushongedza kwakanaka mumamiriro akasiyana ezvakatipoteredza.
Hapana kuputika kana kudonha kunoshandiswa mu weld
ZINDN yakagadzirisa iyo indasitiri bhodhoro iyo galvanizing layer inotsemuka uye inodonha inopa mune weld, inova nechokwadi chemhando yekushandisa.
Nyore kushandisa
One pack, inogona kuiswa nekupfapfaidza, kubhurasha kana kukunguruka.Haisi kunyura pasi, haivharidzi pfuti, haivharidzi pombi, inoshandiswa zviri nyore.
Mari inoshanda
Eco-inoshamwaridzika, yakaderera mutengo, uye nyore kubata zvichienzaniswa nekupisa-dip uye thermal spray galvanizing.
Nguva refu pakati pekubata kumusoro uye kudzokorora, mutengo wakaderera wehupenyu kutenderera anticorrosion uchienzaniswa ne epoxy zinc yakapfuma machira.

Degreasing uye decontamination
Mavara emafuta epamusoro anofanirwa kucheneswa ne-low-pressure spray kana bhurashi rakapfava rine muchenesi chaiwo, uye zvese zvakasara zvinofanirwa kugezwa nepfuti yemvura yakachena, kana kurapwa nelye, murazvo, nezvimwewo, uye yosukurudzwa nemvura yakachena kusvika isina kwayakarerekera.Nzvimbo diki dzemavara emafuta dzinogona kukweshwa nezvinonyungudutsa.
Kurapa kwepamusoro
Shandisa maturusi ejecha kana maturusi emagetsi uye maturusi emaoko kuti ubvise ngura, maprotrusions, uye kusvuura mativi pamusoro, kunyanya mativi ane ngura, uye mativi akaomarara anokwenenzverwa newelding.
Musanganiswa
ZINDN chinhu chimwe chete chechikamu chigadzirwa.Mushure mekuvhura dhiramu, inoda kubvongodzwa zvachose nemudziyo wemagetsi.
Dilute chiyero 0-5%;nekuda kwekusiyana kwekushisa uye kupfapfaidza pombi yekumanikidza, iyo chaiyo yekuwedzera yekutetepa kunobva pane chaiyo mamiriro.
Application
Kubhurasha nekukunguruka: mabhurashi ependi asingadere uye ma roller cores anokurudzirwa, uye shandisa nzira yecriss-cross kupfekedza zvakaenzana kuti uve nechokwadi chekupinda kwakanaka, uye teerera kudzivirira kudonha uye kusaenzana.
Kupfapfaidza: pombi yekupfapfaidza ine reshiyo yekumanikidza ingangoita 1:32, uye chengeta michina yekupfapfaidza yakachena.
Z-mhando yemuromo inokurudzirwa, chengetedza hupamhi hwekupfapfaidza inenge 25cm, muromo uri perpendicular kune workpiece pa 90 ° C, uye pfuti kureba inenge 30cm.
Ratidza kupfapfaidza ne2 coatings layers, Mushure mekunge pamusoro pekutanga kwaoma, pfapfaidza kechipiri, dzorera pfuti kaviri, uye shandisa kune yakatsanangurwa firimu ukobvu zvinoenderana nezvinodiwa.
