Primer ku metal ukusetshenziswa ongaphandle: izici, ukusetshenziswa, izinga lokushisa, ukugeleza. Primer ku metal umsebenzi ongaphandle ngezandla zabo

Uma udinga primer on metal ukusetshenziswa ongaphandle, kubalulekile ukufunda indlela lelisetjentiswa futhi iziphi izinhlobo Ukwakheka khona. Ungagxambukeli, nezeluleko ezisebenzayo izokwethulwa kulesi sihloko. Kuyaphawuleka ukuthi isizinda ngaphambi kokufaka upende kufanele uzilungiselele, Nokho, empeleni master yangasese imisebenzi wokulungiselela dengwane. Ngokuvamile, abantu abangafuni uqonde okushiwo ebusweni priming, qala ukusebenzisa colorants ngqo metal, esiphezulu kungagcini kuphela ngokususa ubudala ungqimba enamathela zokuhlobisa. Kwezinye izimo, ukususwa ezinengilazi ubudala futhi kukhiqizwa. Ezinye nabathakathi wenziwa kuphela ashanele nokugqwala degreasing ebusweni. Primer ku metal ngoba Ingaphandle Okwamanje kunezinzuzo eziningi.

Isidingo priming

Uma usebenzisa i-primer phambi yokudweba steel, linganikeza umbala kangcono. Uzokwazi yokuthuthukisa izici ingcina ingxube yokuqinisa isisekelo. Phakathi kwezinye izinto, primer uyakwazi ukunciphisa porosity ebusweni evumela isicelo kapende ukwakhiwa ungqimba ohlabayo. Lokhu kwehlisa ukusetshenziswa impahla, kanye imali nesikhathi. Le ncwadi uyakwazi ukuthuthukisa izici amanzi-oxosha futhi kuvimbele ukugqwala izinqubo. Lokhu kungenzeka uma yokuqedela ngabe kabana ngesikhathi ukusebenza. Primer ku metal ukusetshenziswa ongaphandle ungakwazi ukwandisa kuso sonke isikhathi sokusebenza impahla.

Izinhlobonhlobo kwenziwa ngoba metal

Phakathi zezintaka kwenziwa kungenziwa isehlane converters elingase ukuguqula oxide yensimbi kolunye kwakwakhe. Njengengxenye yalolu ingxube iqukethe orthophosphoric acid, okuyinto emva isicelo uqala uxhumana ukugqwala. Ekugcineni, kukhona ukuphendula, okuvumela ukuba uthole phosphate yensimbi. Lesi sakamuva, esikhundleni salokho, ihlanganisa ebusweni ifilimu okuqinile, okuyinto kuyahluka izici amanzi. Lokhu kwanele ngempela ukuvimbela okuvela kuyo ukugqwala izinqubo ngesikhathi ukulimala ungqimba upende. Umonakalo ungase benza aqhephukile, amazinyo aqhephukile noma uyaxebuka. Primer ku metal ukusetshenziswa Ingaphandle kuqondene kakhulu labo izinto beshaywa kabi egqwalile.

Abavikeli

Lokhu zilwane primer coating yama-materials lapho Ingxenyana encane yalawo izinhlayiya metal kuthiwa yahlakazeka. Kuye umakhi, bangase khona ukwakheka in imali engaba amaphesenti angu-92. Ngenxa yalokho, kungenzeka ukuthola isakhiwo metallized, okuyinto emva isicelo phezu kudala ifilimu elincanyana zokuzivikela, okuyinto has high amandla izici. Uma umenzi akusho linqume imikhawulo imiyalelo, ungasebenzisa primer enjalo cishe wonke evele, njengoba kuba jikelele.

sequestering

Primer ku metal umsebenzi ongaphandle ngezandla zabo singasetshenziswa ngaphandle kosizo lukachwepheshe ezengeziwe. Singasho sequestering ejenti ukuthi ukubambezela ngesikhathi yezinqubo zamakhemikhali. Ngisho noma enamathela enjalo wokulungiselela yangaphandle uzobe ezilimele ngesikhathi kokuhlinzwa, metal ngeke uxhumana ketshezi akuyona kanjalo maduze. izingoma ezinjalo ziwusizo kakhulu ezimweni lapho ebusweni echayeke mechanical action hlobo ukushaqeka noma ukuhilizisana.

insulators

Uma ungumnikazi primer on metal ukusetshenziswa ongaphandle kuzosetshenziswa, kubalulekile ukutadisha izimfanelo Ukwakheka kusengaphambili. Ngakho, kungenzeka ukuthi yisivikelo zokwakha emakethe akhethiwe, esekelwe - bendabuko Umbala izingoma elibomvu phambili uhlobo. Basuke iqondiswa fillers ahlukahlukene azidlulisele izici ezithile ingxube. Le filimu kwakhiwa emva ukwelashwa surface okuyinto, uyakwazi thembeke ukuhlukanisa base kusukela nomthelela ketshezi. Njengoba isibonelo esisodwa i ezinjalo izenzo oxide resin. Ngokuvamile lezi Izingxube zisetshenziselwa izinsimbi ayoni kanye nensimbi.

primer Amabili ingxenye

Lezi imisindvo kungaba kubhekwe njengendlela zinhlobo passivating Nokho, ngokushesha baqalaza ifa umphumela ethuthukisiwe okunikezwa khona izingxenye ekhethekile. Ngu kwenziwa ezinjalo kunconywa ukulapha noma isiphi izinsimbi kanye Alloys.

Izici ezisebenzisa ngayo primer on metal

Uma primed ngoba metal ngoba Ingaphandle izosetshenziswa, ukusetshenziswa izinga lokushisa kufanele kucatshangelwe kusengaphambili. Ngokuvamile, ubuchwepheshe umsebenzi uhlala kubo bonke Ukwakheka zilwane okufanayo. Ekuqaleni, kudingeka balahle ubudala yokuqedela elingenamikhono, usebenzisa ibhulashi steel. Surface kumele roughened, uma base kuyinto olubushelelezi ezahlukene. Lokhu kwandisa izici adhesion. Ngaphezu kwalokho kungenzeka ukuqhubekela isicelo, ungqimba wokuqala ezondile kwengoma. Ngemva ingxube wayegxile, kungaba kwenziwe reapplication. Kubalulekile ukuba acabangele ukusetshenziswa material. Ngakho, eneminyaka engu-15 square metres kuthatha cishe eyodwa kilogram kokuqanjiwe. Kuyadingeka ukuba acabangele ngaphambi kokuthenga isitoko.

izinga lokusebenza

Uma primed ngoba metal ngoba Ingaphandle izosetshenziswa, kubalulekile ukuba acabangele ukusetshenziswa, kulapho-ke usevele eyaziwa, kodwa kubalulekile ukuba acabangele isicelo ukushisa. Akufanele ukuqala umsebenzi uma lokushisa kuma kwaba degrees 30. Kulokhu, ukwakheka zingashintsha Ukucaciswa zabo, futhi uzobe banqanyulwa isinyathelo omiswe.
