Zosindikizira zamagalimoto
Zamkatimu
Automotive sealant ndi chinthu cha viscous, chonga phala chomwe chimagwiritsidwa ntchito kusindikiza kutayikira m'galimoto. Ndi kugwiritsa ntchito koyenera kwa kapangidwe, kutuluka kwa antifreeze, madzi, mafuta ndi madzi ena amagalimoto kumatha kuthetsedwa. Itha kugwiritsidwanso ntchito kulumikiza malo osiyanasiyana ndikudzaza ming'alu.
Mitundu ya zosindikizira zamagalimoto
Zosindikizira zamagalimoto zitha kugawidwa molingana ndi njira zambiri, koma zochulukira kwambiri ndizo: popanga (silicone, anaerobic, synthetic, polyurethane ndi kutentha) komanso pogwiritsira ntchito (kwa thupi, matayala, makina otulutsa, ma radiator, magalasi ndi nyali zakutsogolo , injini, etc.).
Silicone sealants
Zosindikizira zopangidwa ndi silicon ndizosatentha komanso zimapirira kutentha mpaka +300 ° C. Zitha kugwiritsidwa ntchito pazinthu zambiri za injini. Zomwe zimadzaza mipata mpaka 6 mm wandiweyani, zimagonjetsedwa ndi kuthamanga kwambiri komanso kuthamanga kwa ntchito.
Pogwira ntchito ndi silicone yosindikizira kutentha kwa galimoto, m'pofunika kuyeretsa bwino zigawo zomwe zigwirizane nazo, zomwe zimakhala zochepa.
Kuchuluka kwa nyimbo za silikoni: kusindikiza mipata mpaka 7 mm kukula kwake pamtunda uliwonse wa injini, ma gearbox, ma axles akutsogolo ndi kumbuyo kwagalimoto, zolumikizira ndi ma cylinder liners, komanso gluing pulasitiki ndi magalasi - zowunikira, zowunikira, magetsi, ma brake magetsi.
Anaerobic sealant
Zosindikizira za Anaerobic zimakhala ndi zinthu zomwe zimaumitsa pokhudzana ndi zitsulo pamalo opapatiza pomwe mpweya wa mumlengalenga sungathe kulowa. Chifukwa chake, kuti kapangidwe kake ka polymerize, ndikofunikira kulumikiza mwamphamvu magawowo.
Ubwino wa nyimbo za anaerobic umaphatikizanso kukana kwambiri kumadera amphamvu amankhwala, kugwedezeka, kutsika kwamphamvu komanso kutentha. Kupangako kumalepheretsanso dzimbiri, makutidwe ndi okosijeni, gasi komanso kutayikira kwamadzimadzi.
Monga kuipa kwa zinthuzo, munthu akhoza kutchula kudzazidwa kwa mipata yaying'ono kuyambira 0,05 mpaka 0,5 mm. Cholumikizira chidzafunika kuti chiwongolere zomwe zidapangidwa pamalo omwe siachitsulo kapena kutentha kotsika.
Kuchuluka kwa zosindikizira za anaerobic ndi kusindikiza, kukonza ndi kusindikiza maulusi opangidwa ndi flanged, mbali za cylindrical ndi welds.
Synthetic sealant
Synthetic sealants ndi chinthu chatsopano chomwe sichinatchulidwebe kwambiri pakati pa amakanika ndi oyendetsa galimoto. Komabe, nkhaniyi ili ndi maubwino angapo:
Mkulu elasticity.
Kukana kwa chinyezi chachikulu, ultraviolet, kuwonongeka kwamakina.
Zinthu zomatira zapamwamba, zomwe zimapewa kusamalidwa kale pamwamba musanagwiritse ntchito sealant.
Kusavuta kugwiritsa ntchito.
Multifunctionality ndi kusinthasintha.
Okonza magalimoto ena ndi okonda magalimoto amati kusinthasintha kwake kumabwera chifukwa cha kuipa kwa zinthuzo. Anthu ambiri amakonda zosindikizira zopapatiza zomwe zimapangidwira zinthu zenizeni ndi zigawo zagalimoto.
Polyurethane sealant
Kumangirira malo osiyanasiyana ndipo amapangidwa mumitundu yosiyanasiyana, yomwe imakulolani kuti musankhe mthunzi wokonzekera pamalo owonekera. Mankhwala a polyurethane amagwiritsidwa ntchito ngati zosindikizira zomata mazenera agalimoto, kukonza nyali zakutsogolo, zomata, komanso kuchotsa mipata muzinthu zathupi.
kutentha sealant
Amagwiritsidwa ntchito pazigawo zonse za injini ndi zida zina. Zosakaniza zimapangidwa zomwe zimatha kupirira kutentha mpaka madigiri 3500. Koma kukonza mbali injini chipinda zokwanira kupirira madigiri 2000.
Malo ogwiritsira ntchito ma autosealants
Kutengera cholinga, mankhwalawa amagwiritsidwa ntchito ngati sealant:
nyali zamagalimoto. Imakulolani kuti mubwezeretse kulimba kwa ma optics ngati kuwonongeka kapena kusintha magalasi akutsogolo.
mawindo agalimoto. Njira yabwino kwambiri yomata pagalasi lagalimoto lagalimoto ndi njira zina zoyendera;
injini yamagalimoto. Njira yabwino yowonetsetsera chitetezo chazinthu zamagawo amagetsi. Amagwiritsidwa ntchito posintha mpope, kusindikiza chivundikiro cha valve ndi poto yotumizira;
matayala agalimoto ndi ma disks. Imathandiza pakagwa mwadzidzidzi, i.e. pa punctures ndi kuwonongeka kwa chipinda ndi matayala opanda machubu. Imakulolani kuti mukonze mwamsanga mumsewu;
mpweya wozizira wagalimoto. Zimathandiza osati kuthetsa, komanso kupewa kutayikira kwa refrigerant, choncho nthawi zambiri amagwiritsidwa ntchito ngati prophylactic;
magalimoto seams. Amagwiritsidwa ntchito pokonzanso thupi - kusindikiza seams za hood, thunthu, pansi, zitseko.
kusindikiza ulusi. Zolemba zomwe zimapangidwira kuti zilumikizidwe ndi ulusi zimalepheretsa kutayikira pamalo otsetsereka a hoses ndi mapaipi. Amapereka ulusi wolimba kwambiri ngakhale pansi pa kupanikizika kwambiri.
Zosankha Zosankhira Sealant
Posankha chosindikizira, muyenera kulabadira kutsata kwaukadaulo wake ndi mawonekedwe a magwiridwe antchito.
Gawo lofunikira posankha chosindikizira ndi zomwe zimagwira ntchito muzopangazo: kuchuluka kwa kukana kukakamizidwa ndi kugwedezeka kwa katundu, kukhazikika pambuyo pakuumitsa ndi kukhazikika.
Kukhalapo kwa dispenser ndi kufunikira kwa mfuti ya caulking kumathandizanso pa chisankho cha caulking agent.
Ngati chosindikiziracho chimadziwika ndi kukana kutentha kwambiri, sichiyenera kugwiritsidwa ntchito pazigawo za injini.
Palibe chifukwa chogula zosindikizira mu phukusi lalikulu la voliyumu: sikoyenera kusunga chosindikizira chotsalira, chifukwa chidzataya katundu wake pakapita nthawi.
Oyendetsa galimoto amaganiziranso kuti chinthucho chiwuma nthawi yayitali bwanji. Monga tanena kale, nyimbo za anaerobic zimawumitsa pokhapokha ngati palibe kukhudzana ndi mpweya. Izi zikutanthauza kuti dalaivala ali ndi nthawi yodekha komanso mosafulumira kugwiritsa ntchito wothandizira pamwamba pa zigawozo ndikuzigwirizanitsa popanda mantha kuti chinthucho chidzaumitsa pasadakhale.
Silicone sealants amachiritsa mkati mwa mphindi 10, koma safuna kulondola kwapadera, kotero amatha kugwiritsidwa ntchito ngakhale ndi madalaivala osadziwa. Komano, kugwiritsa ntchito mankhwala silikoni ndi koyenera pamene kusindikiza mipata yakuya, pamene mankhwala anaerobic amatha kudzaza zosagwirizana ndi kuya osapitirira 0,5 cm.
Malingaliro atsatanetsatane ogwiritsira ntchito zosindikizira, komanso chidziwitso cha kutalika kwa kusindikiza kumatenga kuti ziume, zingapezeke mu malangizo operekedwa ndi wopanga. onaninso
