Vagadziri vezvipfeko vakataura kuti mvura-inonyungudutswa yemvura inoreva majasi akagadzirwa kubva emulsion semafirimu ekugadzira zvinhu, umo solvent-based resins inonyungudutswa mune organic solvents, uyezve, nerubatsiro rwe emulsifiers, resin inoparadzirwa mumvura neakasimba mechanical. kukurudzira kuumba emulsions , inonzi post-emulsion, inogona kuderedzwa nemvura panguva yekuvaka.
Pendi yakagadzirirwa nekuwedzera emulsion shoma kune resin inonyungudika nemvura haigoni kunzi latex paint. Kunyatsotaura, pendi inoonda mvura haigone kunzi latex pendi, asi zvakare inorongedzerwa se latex pendi negungano.
Zvakanakira uye zvisingabatsiri zvemvura-based coatings
1. Kushandisa mvura semunyungudutsa kunochengetedza zviwanikwa zvakawanda. Njodzi dzemoto panguva yekuvaka dzinodziviswa uye kusvibiswa kwemhepo kunoderedzwa. Inongova shoma shoma shoma-chepfu doro ether organic solvent inoshandiswa, iyo inovandudza mamiriro ekushanda.
2. Iyo organic solvent yeyakajairika mvura-based pendi iri pakati pe10% ne15%, asi ikozvino cathodic electrophoretic pendi yakaderedzwa kusvika isingasviki 1.2%, iyo ine mhedzisiro yakajeka mukuderedza kusvibiswa uye kuchengetedza zviwanikwa.
3. Kupararira kugadzikana kune simba rakasimba remagetsi rine hurombo. Kana kumhanya kwepombi yekufambisa kuchisiyana zvakanyanya, zvimedu zvakaparadzirwa zvinotsikirirwa kuita zvimedu zvakasimba, izvo zvinokonzeresa kupinza pafirimu rekuputira. Zvinotarisirwa kuti pombi inotakura iri muchimiro chakanaka uye mudhuri wepombi hauna hurema.
4. Inonyanya kukanganisa kune midziyo yekupfekedza. Rining inodzivirira Corrosion kana simbi isina simbi inodiwa, uye mutengo wemidziyo wakakwirisa. Corrosion uye kunyungudika kwesimbi kwepombi inotakura kunogona kukonzera kunaya uye kugova kwezvikamu zvakapararira pafirimu rekuputira, saka pombi dzesimbi dzisina tsvina dzinoshandiswa zvakare.
Kupedzisa kushandiswa uye nzira yekuvaka yevagadziri vepende
1. Gadzirisa pende kune yakakodzera spray viscosity nemvura yakachena, uye kuyera viscosity neTu-4 viscometer. A viscosity yakakodzera kazhinji 2 kusvika 30 seconds. Mugadziri wepende akataura kuti kana pasina viscometer, unogona kushandisa nzira yekuona kumutsa pende nesimbi yesimbi, fambisa kusvika pakakwirira 20 cm uye umire kutarisa.
2. Mhepo yemhepo inofanira kudzorwa pa 0.3-0.4 MPa uye 3-4 kgf / cm2. Kana dzvinyiriro yakanyanya kuderera, pende haizogadziri atomize zvakanaka uye nzvimbo yacho ichapinzwa. Kana dzvinyiriro yacho yakakurisa, zviri nyore kudonhera, uye mhute yependi yakakura kwazvo kuti isarase zvinhu uye inokanganisa hutano hwevashandi vekuvaka.
3. Nharaunda pakati pemuromo nepamusoro pechinhu ndeye 300-400 mm, uye zviri nyore kunyura kana iri pedyo. Kana iri kure, mhute yepende inenge isina kuenzana uye pachava negomba. Kana muromo uri kure nechiso chechinhu, mhute yepende ichawarira munzira, ichiparadza. Mugadziri wepende akataura kuti chinhambwe chaicho chinogona kutariswa zvinoenderana nerudzi rwependi, viscosity uye kudzvanywa kwemhepo.
4. Pfuti yekupfapfaidza inogona kufamba kumusoro uye pasi, kuruboshwe uye kurudyi, uye inogona kumhanya zvakaenzana nekumhanya kwe10-12 m / min. Inofanira kunge yakatwasuka uye yakanangana nepamusoro pechinhu chacho. Pakupfapfaidza kumativi ose epamusoro pechinhu, ruoko runodhonza pfuti yespray inofanira kusunungurwa nokukurumidza. Pa, izvi zvinoderedza mhute yepende.
