Iwo akanakisa maprimers emagetsi emotokari simbi
Zviri mukati
Novice mota mechanics vanowanzo shamisika kuti rudzii rwemusanganiswa wekutenga. Kunyangwe kuziva kuumbwa kwemhinduro inoda kuve yakashongedzwa nemarara emota zvikamu, hazvigoneke nguva dzose kusarudza pasarudzo yemhando. Kune vakawanda vagadziri pamusika vachipa akasiyana emotokari ekutanga. Kuti tibatsire mhizha, isu takanyora epamusoro matatu ekutanga ekugadzira auto galvanizing.
Iyo primer chinhu chakakosha chekugadzirisa muviri wemota yakagadzirwa nesimbi. Unhu hwekuputira nependi yekupedzisa uye varnish zvinhu zvinoenderana nemhinduro inoshandiswa.
Maprimers ekugadzirisa muviri: chinangwa
A primer imhando yemvura inodiwa kugadzirira pamusoro pemota yekushandisa pendi. Vapendi vemotokari vasina ruzivo rwokuzviwanira vanowanzoita zvikanganiso pavanotanga kutanga motokari yemarara pasina kuedza kuona chinangwa chemusanganiswa. Chinhu chimwe nechimwe chinosiyana kwete chete mumhando uye mutengo, asiwo mukuumbwa, izvo zvinokanganisa zvimwe zvimiro zvejasi. Zvichienderana nerudzi rweprimer yekugadzira mota, inoshandiswa ku:
- kuve nechokwadi chekunamatira kwakasimba kwesimbi kupenda;
- kuwedzera anticorrosive properties;
- kuzadza pores uye zviduku zviduku zvakasara mushure mekugaya muchina;
- kuparadzaniswa kwezvikamu zvisingaenderani, izvo, kana zvabatanidzwa, zvinogona kupa mhinduro - kuzvimba kwepende.
Primer types
Nhasi, zvakasiyana-siyana zvekusanganiswa zvinoratidzwa pamusika wemotokari, nerubatsiro rwemichina inogadziriswa. Vose vakakamurwa kuva mapoka makuru maviri:
- yekutanga (primers);
- chechipiri (fillers).
Galvanizing neprimary primers yakakosha kumafekitori uko mota dzinogadzirwa. Zvechipiri zvinonyanya kushandiswa muzvitoro zvinogadzirisa mota kana uchigadzira mota.
Primer types
Primary ivhu
Iyo primer inoshandiswa kupfekedza simbi "isina chinhu", iyo inonyanya kukanganiswa nekuora. Iyo yekutanga primer inoiswa isati yaisa kana mutsetse weimwe mvura mhinduro. Inoita basa rekudzivirira, kudzivirira kuonekwa uye kukura kwemarara. Zvakare, iyo yekutanga yemota isina galvanized mota inova adhesive "murevereri", iyo inopa kunamatira kwakasimba kwesimbi kune inotevera dhizaini yekupenda.
Secondary ivhu
Iyo yekuzadza inoshanda seyekuzadza uye leveler. Basa rayo guru nderokuzadza pores uye craters yakagadzirwa panguva yekuisa, pamwe nekubvisa migumisiro yekusabudirira kugaya, kuyera majoini uye kuchinja. Secondary primers ine yakanaka adhesion uye corrosion resistance, asi maitiro aya akadzikira kana achienzaniswa nemaprimers.
Zvimiro zve galvanizing primer
Nzvimbo yesimbi ine chimiro chakatsetseka chisingakwereteki zvakanaka kupenda. Vese masters vanoziva kuti zvinodikanwa kuprimisa simbi yemotokari kuitira kuti ive nechokwadi chekunamatira kwayo pendi. Mukuwedzera, mashizha ematare pachawo ane high corrosion resistance, asi kana pakaitika tsaona duku, zinc inoparadzwa nyore nyore. Somugumisiro, motokari inodzivirirwa zvisina kuenzana kubva kune ngura, izvo zvinowedzera kutaridzika kwefoci yekuora.
Chinhu chakakosha cheiyo primer yesimbi yemotokari galvanized ndeyekutanga kudikanwa kudzikisa mabasa ekudzivirira ekuputira nekuiisa neasidhi. Muchiitiko ichi, primer ichaitwa zvinobudirira sezvinobvira.
Maitiro ekutanga galvanized mota simbi
Zvinoenderana nehunyanzvi, iyo isina simbi yepasi inofanira kurapwa nemusanganiswa wakakodzera weprimer. Mushure meizvi, zvinokwanisika kuita kupedzisa kuvhara nepende uye varnishes, iyo inodawo kusarudzwa zvakanaka.
Primer for galvanized metal
Kune maprimers anowanikwa ekutengesa akagadzirirwa zvakananga kune zinc nzvimbo. Tichifunga kuti motokari inoshandiswa mumamiriro ezvinhu ane hutsinye, nokuda kwekuputira kwepamusoro-soro, galvanized epoxy-based primer inofanira kusarudzwa. Iyo yakasimba, inopesana nekukuvadzwa kwemichina, ine yakakwirira kunyorova. Kunewo maviri-chikamu cheprimer-enamels anoshandiswa kune "isina" simbi uye panguva imwechete inoshanda se topcoat.
Usati watanga, zvakakosha kuchenesa nzvimbo kubva kune tsvina uye guruva. Iyo simbi inofanira kunge yakaoma kuitira kuti pasave nemakemikari anoitika panguva yekushanda iyo inogona kukanganisa kukanganisa kupfeka. Iyo primer solution iri nyore kushandisa nenzira yeaerosol.
Pendi yemararamiro
Hazvibvumirwi kuvhara simbi nemafuta kana alkyd paints uye varnishes.

Izvo zvakare hazvikurudzirwe kushandisa masanganiswa ane mhangura, tini, antimony. Vanonyanya kuderedza kusimba kwependi yepamusoro. Kune galvanized metal, zvinokurudzirwa kushandisa pendi:
- upfu;
- urethane;
- acrylic.
Iyo yakanakisa inoonekwa sehupfu pendi, yakagadzirwa pahwaro hweepoxy uye mapolymers. Inoshandiswa mukugadzirwa kwekupenda mota, sezvo iine simba rakakura uye kusimba. Izvo chete zvisingabatsiri zvekuputira ndezvekuti zvakaoma kushongedza.

The best primers for galvanized metal
Novice mota mechanics vanowanzo shamisika kuti rudzii rwemusanganiswa wekutenga. Kunyangwe kuziva kuumbwa kwemhinduro inoda kuve yakashongedzwa nemarara emota zvikamu, hazvigoneke nguva dzose kusarudza pasarudzo yemhando. Kune vakawanda vagadziri pamusika vachipa akasiyana emotokari ekutanga. Kuti tibatsire mhizha, isu takanyora epamusoro matatu ekutanga ekugadzira auto galvanizing.
"ZN-Primer" mota epoxy inokurumidza-kuomeswa kwesimbi muviri mapaneru uye welds
Iyo primer yakanakira mota dzakagadzirwa nependi, ichipa yakakwira simbi dziviriro kubva mukuora uye kunamatira kwakanaka. Iko kusanganiswa kunoshandiswa pakurapa mitumbi yemotokari, midziyo yemvura uye zvikamu zviri pasi pe ngura. Iko kuumbwa kunosiyaniswa nekusavapo kwe smudges painoiswa vertically, nekukurumidza kuomesa kukurumidza, kuenderana nemhando dzakasiyana dzemota enamel.

- kushorwa nekunyorova uye chando.
Nzira yekupendesa sei simbi yakabatiswa kuitira kuti irege kusvuuka kwenguva yakareba sezvinobvira
Usati washandisa primer uye pendi pane galvanized mota simbi, gadzirira pamusoro:
- Ita kucheneswa kwezvikamu zvemotokari kubva kuguruva, tsvina, maronda ekuora. Kuti uite izvi, shandisa sandblasting midziyo, sandpaper, mvura ine sipo.
- Zvadaro degrease pamusoro pemvura yakadzika yephosphoric acid kana musanganiswa weacetone uye toluene muchiyero che 1 kusvika ku 1. Inotenderwa kusvibisa kuvhara neparafini, mweya wakachena, chlorine-ine bleach.
Pakarepo mushure mekuita nhanho idzi uye kuomesa zvigadzirwa zvakashandiswa, penda pamusoro. Zvinokurudzirwa kupedza kupenda mukati memaminitsi makumi matatu mushure mekunge waisa mota. Izvi zvichawedzera kunamatira maitiro ezvinyorwa, pamwe nekupa chipfeko chepamusoro-soro. Kuti uwane mhedzisiro yepamusoro, zvinokurudzirwa kushandisa 30-2 zvidimbu zvejasi repamusoro.
