Zvisimbiso zvemotokari

16.02.2023 /

      Automotive sealant iviscous, paste-like substance iyo inoshandiswa kuvhara mvura inobuda mumotokari. Nekushandisa kwakaringana kwekuumbwa, kuyerera kweantifreeze, mvura, mafuta uye mamwe emota mvura anogona kubviswa. Inogona zvakare kushandiswa kubatanidza nzvimbo dzakasiyana-siyana uye kuzadza kuputika.

      Mhando dzemotokari sealants

      Zvisimbiso zvemotokari zvinogona kuiswa maererano nemaitiro mazhinji, asi akanyanya kuwanda ndeaya: nekuumbwa (silicone, anaerobic, synthetic, polyurethane uye tembiricha) uye nendima yekushandisa (yemuviri, yematayi, ye exhaust system, ye iyo radiator, yegirazi nemwenje, yeinjini, nezvimwewo).

      Silicone sealants

      Silicone-based sealants inodzivirira kupisa uye inomira kutonhora kusvika +300 ° C. Dzinogona kushandiswa kune dzakawanda injini zvikamu. Izvo zvinhu zvinozadza mapundu anosvika 6 mm mukobvu, anoshingirira kune yakanyanya kudzvanywa uye kumhanya kwebasa.

      Paunenge uchishanda nesilicone yakakwirira yekushisa sealant yemotokari, zvakakosha kunyatsochenesa zvikamu zvekubatanidzwa, izvo zviduku zvishoma.

      Nzvimbo dzekushandiswa kwesilicone komisheni: kuvhara mapeji anosvika 7 mm muhukuru pane chero nzvimbo dzeinjini, magiya mabhokisi, emberi uye kumashure maaxle emota, majoini uye kusangana kwemacylinder liners, pamwe neaya anonamira zvikamu zvepurasitiki negirazi - maraiti emberi, maraiti eparutivi, mabheji, maraiti emabhureki.

      Anaerobic sealant

      MaAnaerobic sealants anoumbwa nechinhu chinoomesa pakubata nesimbi munzvimbo dzakatetepa umo mweya wemhepo haugone kupinda. Naizvozvo, kuitira kuti kuumbwa kuite polymerize, zvinodikanwa kunyatso batanidza nzvimbo dzezvikamu. 

      Zvakanakira zvekuumbwa kweanaerobic zvinosanganisirawo kuramba kwakanyanya kune hukasha makemikari nharaunda, vibrations, kudonha kwekumanikidza uye tembiricha. Iko kuumbwa kunodzivirirawo corrosion, oxidation, gasi uye kubuda kwemvura.

      Sekukanganisa kwezvinhu, munhu anogona kutumidza kuzadzwa kwezvishoma zvishoma kubva 0,05 kusvika 0,5 mm. An activator inozodikanwa kuita polymerize kuumbwa pane zvisiri zvesimbi kana patembiricha yakaderera.

      Chiyero cheanaerobic sealants kuisa chisimbiso, kugadzirisa uye kuisa chisimbiso chine shinda uye majoini ane flanged, cylindrical zvikamu uye welds.

      Synthetic sealant

      Synthetic sealants chinhu chitsva chisati chawana mukurumbira pakati pe auto mechanics nevatyairi. Nekudaro, chinyorwa ichi chine huwandu hwezvakanakira:

      • High elasticity.

      • Kupokana kune yakakwira humidity, ultraviolet, kukuvara kwemagetsi.

      • High adhesive properties, iyo inodzivisa kusati kwaitwa kurapwa kwepamusoro usati washandisa sealant.

      • Kureruka kwekushandisa.

      • Multifunctionality uye versatility.

      Mamwe ma auto mechanics uye vanofarira mota vanopa kuenderana kwayo nekuipa kwezvinhu. Vanhu vazhinji vanosarudza yakamanikana-profile sealants akagadzirirwa chaiwo zvinhu uye zvikamu zvemota.

      Polyurethane sealant

      Zvisungo zvakasiyana-siyana uye zvinogadzirwa mumhando dzakasiyana-siyana, izvo zvinokubvumira kuti usarudze mumvuri wekugadzirisa munzvimbo inoratidzika. Mishonga yepolurethane inoshandiswa sezvisimbiso zvekunamira mahwindo emota, pakugadzirisa marambi emusoro, pakuisa chisimbiso seams, uyezve nekubvisa mapundu muzvinhu zvemuviri.

      tembiricha sealant

      Inoshandiswa kune ese ejini zvikamu uye zvimwe zvikamu. Misanganiswa inogadzirwa iyo inogona kumira kupisa kusvika ku3500 degrees. Asi kugadzirisa injini compartment zvikamu, zvakakwana kutsungirira kusvika 2000 madhigirii.

      Nzvimbo dzekushandiswa kweautosealants

      Zvichienderana nechinangwa, chigadzirwa chinoshandiswa sechisimbiso che:

      • marambi emotokari. Inokutendera kuti udzorere kusimba kweiyo optics kana ikakuvadzwa kana kutsiviwa kwegirazi remwenje.

      • mahwindo emotokari. Iyo yakanakisa nzira yekunamira hermetically iyo auto girazi windshield yemotokari uye dzimwe nzira dzekufambisa;

      • injini yemotokari. Iyo yakanakisa nzira yekuvimbisa kuchengetedzwa kwezvimiro zvesimba remagetsi unit. Iyo inoshandiswa pakutsiva pombi, yekuvhara chivharo chevhavha uye pani yekutumira;

      • matai emotokari nemadisiki. Inobatsira mumamiriro ekukurumidzira, i.e. pazvibodzwa nekukuvadzwa kwekamuri nematayi asina chubhu. Inokubvumira kuti uite nokukurumidza kugadzirisa mumugwagwa;

      • air conditioner yemotokari. Iyo inobatsira kwete chete kubvisa, asiwo kudzivirira kuputika kwefiriji, saka inowanzoshandiswa seprophylactic;

      • mota seams. Inoshandiswa pakugadzirisa muviri - kuvhara mazamu ehood, trunk, underbody, magonhi.

      • thread kuiswa chisimbiso. Mishonga ine shinda inodzivirira kuvuza papombi uye zvigaro zvepombi. Inopa tambo yakasimba inokodzera kunyange pasi pekumanikidzwa kwakanyanya.

      Sealant Selection Criteria

      Paunosarudza chisimbiso, iwe unofanirwa kuterera kune kutevedza kwehunyanzvi hwayo maitiro uye maficha ekushanda kwezvikamu.

      1. Iyo yakakosha parameter yekusarudza chisimbiso ndeyezvinhu zvezvinhu zvinoshanda mukuumbwa kwechigadzirwa: dhigirii rekupokana nekumanikidza uye mitoro yekudengenyeka, elasticity mushure mekuoma uye kusimba.

      2. Kuvapo kwechigadziro uye kudiwa kwepfuti inoputika inoitawo basa mukusarudzwa kwemumiririri we caulking.

      3. Kana iyo yekuisa chisimbiso inoratidzwa nekusagadzikana kushomeka kune yakakwira tembiricha, haifanirwe kushandiswa pane injini zvikamu.

      4. Iko hakuna chikonzero chekutenga sealants muhombe vhoriyamu mapakeji: hazvina kukodzera kuchengetedza yakasara sealant, sezvo icharasikirwa nemidziyo yayo nekufamba kwenguva.

      Vatyairi vemotokari vanocherechedzawo kuti chinhu ichi chinosvava kwenguva yakareba sei. Sezvatotaurwa pamusoro apa, zvinyorwa zveanaerobic zvinoomesa chete kana pasina kusangana neokisijeni. Izvi zvinoreva kuti mutyairi ane nguva yekudzikama uye pasina kukurumidza kushandisa mumiririri kumusoro kwezvikamu uye kuzvibatanidza pasina kutya kuti chinhu chichaoma mberi kwenguva.

      Silicone sealants inorapa mukati memaminitsi gumi, asi haidi kurongeka kwekushandisa, saka inogona kushandiswa kunyangwe nevatyairi vasina ruzivo. Kune rumwe rutivi, kushandiswa kwezvigadzirwa zvesilicone kwakakodzera pakuvhara mapeji akadzika, nepo anaerobic compounds inokwanisa kuzadza zvisizvo nehupamhi husingapfuuri 10 cm.
