Ini ndinofanira kuprimisa mota ndisati ndaisa?
Zviri mukati
Putty - inoumbwa ine fomu yepurasitiki uye yakagadzirirwa kuzadza mhango yakaumbwa nekuda kwekukuvadzwa kwechinhu. Nekuda kwehunhu hwechiito cheprimer uye putty musanganiswa, kurongeka kwekushandisa kwavo kwakasiyana - kutanga, kuremara kukuru kunobviswa, ipapo kuumbwa kunogoverwa, izvo zvinoita kuti kuvimbika kusungirirwa kwepende uye nzvimbo yakarapwa.
Paunenge uchiita kugadzirisa muviri pachavo, vamwe vatyairi havazivi kutevedzana kwezviito, kusava nechokwadi kana primer kana putty inotanga kuiswa kumotokari. Isu tinozoona mune kurongeka kwevashandi vanogadzira muviri wemotokari.
Kusiyana pakati peprimer uye putty
Chinangwa chikuru cheiyo primer ndechekuvandudza kunamatira pakati peakaiswa matinji ependi (LCP). Mukuwedzera, inoita mamwe mabasa:
- Inobvisa mabhubhu emhepo kubva kune zvidiki zvidiki zvenzvimbo yakarapwa (makwara, machipisi, asingaoneki neziso rakashama).
- Inoshanda sechinhu chekubatanidza chezvikamu zvisingaenderane zvakanaka uye zvinogona kupinda mumakemikari reaction, zvichizobuda kunze.
- Inodzivirira kubva kunze kwekunze - kusangana nemvura, mhepo, jecha uye zvimwe zvinhu. Pamusana pekuti iyo primer inodzivirira kupinda kwekunze kune simbi, kuumbwa kwekuora kunobviswa.

Car body priming
Ndinofanira kutanga ndisati ndaisa
Iyo tekinoroji yekugadzirisa nhengo dzemuviri usati wapenda haisanganisi priming usati washandisa putty. Kugadziriswa kwekugadzirisa kwakagadzirirwa kushandiswa kune "isina" simbi, kunamatira kwakanaka kunowanikwa nekuwedzera zvakakosha zvikamu kwairi.
Kuisa mota isati yaiswa kunobvumidzwa chete kana musanganiswa uine epoxy. Vanopenda vanoita izvi pavanenge vachigadzirisa kwenguva refu nhengo dzemuviri. Kazhinji kazhinji, kudzoreredza uye kudzoreredza basa rinotora nguva refu. Kana iyo simbi inoratidzwa kumhepo yakazaruka, mumamiriro ekunyorova kwepamusoro, maitiro ekuora anoitwa.
Inobvumirwa kutanga simbi isati yaisa motokari kusvikira yaoma zvachose. Izvo zvinoumba maturusi ese ari maviri anodyidzana uye akabatana zvakasimba. Kuvandudza kunamatira, nzvimbo yacho inocheneswa zvishoma nekubvisa zvinhu zvakabuda.
Zvinoita here kuisa putty pane yekare pendi
Kuisa pendi yekare kunonzwisisika kana pane kunetseka pamusoro pekuonekwa kwekuora nguva pfupi mushure mekurapa. Kuti uvandudze kunamatira, zvinokurudzirwa kubata pendi nejecha, zvichipa porosity. Iyo putty inozopinda mukati meaya pores uye inonamira yakasimba.
Maitiro ekuisa putty pane yekare pendi:
- Chenesa nzvimbo kuti irapwe munzvimbo dzine dambudziko - bvisa pende yakazvimba, bituminous stains, nezvimwe.
- Degrease the body element ne solvent, doro.
- Gadzirisa zvinenge zviripo.
Izvo zvinokwanisika kuisa iyo putty kuumbwa chete papende iri mumamiriro akanaka - haina kuputika, machipisi, kana kuputika. Kana pane kukanganisa muhuwandu hukuru, zviri nani kuchenesa pendi yekare kune imwe nzvimbo yesimbi.
Maitiro ekusarudza iyo chaiyo putty, maficha ekushandisa
Kuumbwa kweputty kunosarudzwa zvichienderana nedambudziko remuviri wakagadziriswa chinhu. Marudzi emaputty anosiyana kubva kune mumwe nemumwe nechinhu chinoshanda:
- Fiberglass. Iyo inoshandiswa kubvisa zvikanganiso zvakakura, sezvo fiberglass fibers ine chimiro chakashata, inoda kugaya kunotevera uye kushandiswa kwekupedzisa. Zvinhu zvakadaro zvinoratidzirwa nekuumbwa kwenzvimbo yakaoma yekugadzirisa, iyo inopesana nekukuvadza kunyange pasi pemutoro unorema.
- Nezviyo zvakakura. Inoshandiswa kurapa kwakashata kwenzvimbo dzine kukuvara kukuru. Inosiyana mupurasitiki uye yakanyatsoiswa yakaoma-kusvika-nzvimbo. Pamusana pekuvapo kwezvikamu zvakakura mukugadzirwa, iyo primer haina kuderera uye inoratidzirwa nekuwedzera kunamatira.
- Nezviyo zvakanaka. Vamwe vanyori vanoitumidza kuti kupera, sezvo inoshandiswa kugadzirisa zviduku zvishoma. Iyo yakanaka-grained primer inogadziriswa nyore nyore nejecha, hapana mavanga kana zvimwe zvinoonekwa zvinokanganisa pamusoro. Iyo primer yakakodzera kuzadza kwete simbi chete, asiwo mapurasitiki, fiberglass zvinhu.
- Acrylic based. Chimiro hachina kufanana neyakajairwa putty - iyo acrylic kuumbwa imvura, muchimiro inofanana neyekutanga. Inoshandiswa pakuzadza nzvimbo dzakakura, ipurasitiki uye iri nyore kushandisa. Mugadziri wechigadzirwa anobvumira kupenda nzvimbo yakarapwa pasina priming inotevera.
Maitiro ekushandisa iyo putty composition:
- Chenesa pamusoro.
- Coarse-grained (fiberglass) filler inoiswa muhombe pores.
- Fine-grained kana acrylic putty inobvisa zviduku zvishoma.
- Primed uye pendi bodywork.
Nzira yekusarudza uye kushandisa primer
Usati wanyorera, zvinodikanwa kuti udzidze mhando dzemusanganiswa wekutanga, nekuti chiyero chekushandisa kwavo chinosiyana zvichienderana nechinangwa.
Nzira yekugaya primer
Mhando dzevhu:
- Epoxy based. Iyo inoratidzirwa nechimiro chemvura, pamwe nezviri mukati mechromium. Inosiyana mukupokana nekupesvedzera kweanehasha makemikari komisheni, inokanganisa kuumbwa kwengura. Epoxy primer haidi kuwedzera kubviswa pamberi pekupenda (kunze kwekunge iyo yakagadzirwa yakashandiswa zvisina kunaka uye mitsetse yakaumbwa).
- Primary. Chinangwa chikuru ndechekudzivirira kwekudzivirira-kuora kwenzvimbo dziri pasi pekusangana kwakananga nemvura. Inobvumirwa kushandisa primer isati yaisa motokari.
- Yakasimbiswa. Inobvisa kusangana pakati pezvikamu zviviri zvepende uye varnish uye haibvumiri kukanganisa kweimwe kune imwe (pende inogona kunge iine hutsinye hwemakemikari emakemikari anoparadza putty).
Ground application process:
- Chenesa zvikanganiso zvinoonekwa pane putty nekubvisa zvinhu zvakabuda.
- Degreisa nzvimbo yakagadziriswa ne solvent, doro, peturu.
- Isa primer mune akati wandei akaturikidzana, pakati peimwe neimwe inodiwa kutora zororo reinenge 90 maminetsi kuti uome.
Iwe unogona kuona kana iyo inotevera dhizaini yakaomeswa nechitarisiko chayo - ichave yakasviba uye zvishoma rough.
Izvo zviri nani - priming kana puttying mota
Mubvunzo wakafanana unobvunzwa nevanotanga mubhizinesi rekupenda. Ivo havanyatso nzwisisa chinangwa chezvose zviri zviviri uye havaoni mutsauko mukushanda. Kunyange zvazvo vamwe vagadziri vekutanga vachibvumira kushandiswa kwavo pasimbi isina chinhu, kwete chigadzirwa chose chinogona kubvisa kukanganisa kwependi. Kuzadza magomba mahombe pasina kushandisa putty hazvigoneke, saka, kana uchisarudza chizadziso chekugadzirisa chinhu chimwe nechimwe chemuviri, zvinodikanwa kuti uswedere wega.
