Kurwisa Underbody Corrosion neSealant

Muviri wemotokari unogona kuva wakanaka, asi pasi haigoni kufuratirwa. Kunyange kana motokari ichipenya ne polish, pasi inogona kuramba yakarasika zvisingagoneki. Kuora kwepasi ndiyo chiyero chekutadza chekuongorora kwehunyanzvi. Chinhu chega chinopa chengetedzo yakavimbika yemavhiri anovhara, sill uye underbody kubva mukuora ndeye cavity coating uye sealant. Nehurombo, hapana kana imwe yematanho inopa mhinduro yekusingaperi uye nguva nenguva kutarisa, kunyanya mumotokari dzechikuru, zvinodikanwa. Gwaro iri rinenge riri pamusoro pekuvharisa pasi (Am: primer) uye ichakuudza zvese zvaunoda kuziva nezve nyanzvi yekuisa chisimbiso kudzivirira ngura.

Musanganiswa haushandi

Mota dzichiri kugadzirwa kazhinji nemapanera esimbi. Hapana chimwe chinhu chinopa chiyero chakanaka chekutonhora chimiro, simba uye mutengo unonzwisisika. Izvo zvakanyanya kusakosha kwesimbi mapaneru ndeyepamusoro pesimbi. Mukubatana nehunyoro - uye mumamiriro ezvinhu akaipisisa - nemugwagwa munyu, simbi inotanga kuita ngura. Kana izvi zvikasaonekwa uye zvichibviswa nenguva, ngura ichapararira zvishoma nezvishoma.

Underseal inobatsira, asi kwete nekusingaperi

Underseal paste inodzivirira, kazhinji ine bhitumini, yakanakira kuvhara pasi. . Mazuva ano, chidziviriro chekudzivirira chinoshandiswa kumotokari itsva panguva yekuvaka, iyo inogara kwemakore akawanda. Underseal inoshandiswa muchikamu che ½ mm. Rubbery substance inozadza makomba ejecha uye haikweshe. Nokufamba kwenguva, sealant inowanzooma. Nokudaro, mushure memakore anopfuura 8, ganda rekudzivirira rinofanira kunyatsoongororwa. Kana paine pakatsemuka kana dhizaini ichibviswa, chiito chekukurumidza chinodiwa.

Musungo unonzi chisimbiso chekare

Dzimwe nguva hunyoro hunovhara mujasi rekare rekutanga. Kana mvura yemunyu ikapinda pakati pechidziviriro chekudzivirira uye pepa resimbi, haizokwanisi kubuda. Mvura yakasara pasimbi inokonzera ngura. Muchiitiko ichi, chisimbiso chekare chemafuta chinoita zvinopesana nechinangwa chayo chepakutanga - panzvimbo yekudzivirira kubva pakuora, inokurudzira kuumbwa kwemarara.

Kushandiswa uye kuvandudzwa kwepasi pasi

Naizvozvo, kupfapfaidza dhiri re dinitrol kana tektyl ​​pane yekare dhizaini haibatsiri zvakanyanya. Kuti uchengetedze zvachose chikamu chepasi chemotokari kubva pakuora, iyo yekare ye sealant inofanira kubviswa. Nhau yakashata ndeyekuti zvakaoma kana kuti zvinodhura. Nhau dzakanaka ndedzekuti nzvimbo dzakakuvadzwa zvakanyanya chete dzinoda kurapwa. Sezvo mutemo, aya ndiwo mapendero ezvikumbaridzo kana mavhiri emavhiri. Iyo yepamusoro inosimbisa chikamu chepakati chepasi chinowanzogara chakafanana muhupenyu hwese hwemotokari.

Pazasi Layer Removal Procedure

Pane nzira nhatu dzekubvisa chisimbiso chepasi:
1. Manual kubvisa ne scraper uye simbi bhurashi
2. Kusvirwa
3. Kuputika kwejecha

Kubvisa nemaoko ne scraper uye bhurashi kunonyanya kuoma uye kunonyanya kukodzera kubvisa rase rust munzvimbo dzinoonekwa maburi. . Kushandisa tekinoroji hakushandiswi zvishoma pano. Viscous bitumen inovhara mabhurashi anotenderera uye sandpaper nekukurumidza. Yakagadzikana basa remaoko ndiyo yakanakisa sarudzo. Pfuti inopisa inogona kuita kuti basa rive nyore, kunyanya munzvimbo dzakaoma-kusvika.

Kusvirwa itsika yevanoda kuzvidzidzisa vanatenzi . Isu tinoraira zvakasimba kusatamba nemoto. Usati waziva, wapisa mota yako uye saka garaji rako rese.

Pakupedzisira, sandblasting inzira yakakurumbira yekubvisa chisimbiso chepasi. . Pane nzira mbiri dzakasiyana dzakasiyana: hasha и isina-abrasive . Kana abrasive blasting iyo granular material inodyiswa pasi pemotokari uchishandisa mweya wakamanikidzwa. Iyo inonyanya kuzivikanwa nzira ndeye sandblasting, kunyangwe paine akati wandei angangoita mabrasives: kubika pasoda, girazi, epurasitiki granules, nutshells uye nezvimwe zvakawanda. Kubatsira kweabrasive blasting inovimbiswa kubudirira. Iyo yekudzivirira inobviswa kubva pasi nekukurumidza uye inobudirira, uye yakachipa zvakanyanya. Kutadza kwake ndiko kuwanda kwemarara ainogadzira. Mukuwedzera, nekuda kwekunyanya kudzvinyirira kana kukanganisa kusina kunaka, hutano hwepasi hunogona kukuvara. Imwe nzira inoshanda ndiyo nzira dzisiri dzekuputika : Panzvimbo yeabrasive yakaoma, yakaoma ice blasting inoshandisa chando che carbon dioxide granules iyo inoputika kana ichirova chidziviriro chekudzivirira, ichiibvisa zvakavimbika. Kunze kweiyo yekare yekudzivirira layer, yakaoma ice processing haina tsvina uye yakachengeteka zvachose pasi. Imwe nzira ndeye kuchenesa mvura yakakwira. disadvantage yeiyi neimwe nzira inoshanda chaizvo mutengo wavo. Iyo yakaoma ice blaster yekurenda inodhura approx. €100-300 (£175-265) pazuva. Naizvozvo, nzira iyi inonyanya kukodzera mota dzepamusoro senge mota dzemitambo dzemhando yepamusoro kana mota dzekare. Dry ice blasting nenyanzvi inopa sevhisi inogona kukubhadhara iwe €500-1000.

Kubvisa ngura

Usati waisa chisimbiso chitsva, rimwe basa rekugadzirira rinodikanwa, kunyanya kubviswa kwakakwana kwekusara kwasara. Iyo scraper blade uye brashi inonyanya kushanda, kunyange zvazvo inongobvisa yakasununguka pamusoro pevhu. Iyo angle grinder inokutendera kuti ushande zvakadzika, asi panguva imwe chete iwe uri panjodzi yekukuya zvinhu zvine hutano. Naizvozvo, isu tinokurudzira kushandisa ngura inoshandura. Chinhu chacho chinoshandiswa nebhurashi repende uye chinofanira kubvumirwa kunyura mukati. Kana iyo tsvuku tsvuku yashanduka kuita dema greasy mass, inogona kungobviswa nemucheka. Sezviri pachena, rust hole welding inofanira kugara ichisiiwa kune nyanzvi dzevashandi.

Zvinonyanya kukosha: degrease uye tepi

Kupfeka kunoda zvakafanana nekupenda simbi: pre-degrease pamusoro . Silicone cleaner akabvumikisa kuva akakodzera zvikurusa. Isa chivharo chekudzivirira uye chibvise mushure mekunge chashanda. Mushure maizvozvi, muviri haufanirwe kusangana nezvimwe zvinhu. Kupfapfaidza hazvibvumirwi Wd-xnumx kana mafuta anopinda mukati. Zvikasadaro, unogona kutanga degreasing maitiro zvakare.

Zvese zvinofamba uye zvinopisa zvinongedzo hazvifanirwe kubatwa ne sealant. Nokudaro, zvinokurudzirwa kuvhara giya rekutungamirira uye kupera nepepanhau. Sealant inogona kukanganisa kufamba. Kana yabudiswa, chinhu ichi chinokonzera njodzi yemoto. Saka ita chokwadi kuti hapana chinoitika pano! Tepi kunze kwehwindo sill muhafu. Iyi nzvimbo inodawo kuvharwa.

Chisimbiso chitsva

Mushure mekuputira jecha kana kujecha pasi pasi kune mapaneru asina chinhu, spray primer inokurudzirwa. Izvi zvichabvumira sealant kunamatira zvakanaka. Ingomwaya pane primer uye rega iome.

Underseal parizvino inowanikwa mumagaba aerosol uye inofanirwa kupfapfaidzwa pasimbi layer 0,5 mm . Muchiitiko ichi, hazvikurudzirwi kushandisa zvakanyanya. Chifukidzo chakakora chinodzivirira chinoreva chimwe chinhu kunze kwekutambisa chinhu. Iyo itsva yekudzivirira layer inofanira kubvumidzwa kuoma kwe4 maawa. Mushure meizvozvo, tepi inogona kubviswa. Kuonekwa kwechikumbaridzo ikozvino kunogona kuvezwa muvara wemotokari. Mushure mekuoma, iyo primer inogona kupendwa pamusoro.
