Ama-sealants ezimoto
Okuqukethwe
I-Automotive sealant yinto e-viscous, efana nokunamathisela esetshenziselwa ukuvala ukuvuza emotweni. Ngokusetshenziswa okulungile kokubunjwa, ukugeleza kwe-antifreeze, amanzi, uwoyela kanye nolunye uketshezi lwezimoto kungaqedwa. Ingase futhi isetshenziselwe ukuhlanganisa izindawo ezihlukahlukene nokugcwalisa imifantu.
Izinhlobo zama-sealant ezimoto
I-Sealant yemoto ingahlukaniswa ngokuya ngezinqubo eziningi, kodwa ezibanzi kakhulu zazo yilezi: ngokwakhiwa (i-silicone, i-anaerobic, i-synthetic, i-polyurethane kanye nezinga lokushisa) kanye nensimu yesicelo (yomzimba, amathayi, isistimu yokukhipha umoya, i-radiator, izibuko nezibani, injini, njll.).
Ama-Silicone sealants
Ama-sealant asekelwe ku-silicone amelana nokushisa futhi angakwazi ukumelana nezinga lokushisa elifinyelela ku-+300 °C. Zingasetshenziselwa izingxenye eziningi zenjini. Impahla igcwalisa izikhala kuze kufike ku-6 mm ubukhulu, futhi imelana nokucindezela okuphezulu kanye nesivinini somsebenzi.
Uma usebenza nge-silicone ukushisa okuphezulu kwe-sealant yemoto, kuyadingeka ukuhlanza kahle izingxenye ezizohlanganiswa, okuyi-minus encane.
Ububanzi bezingoma ze-silicone: ukuvala izikhala kuze kufike ku-7 mm ngosayizi kunoma yiziphi izindawo zezinjini, ama-gearbox, ama-axle angaphambili nangemuva emoto, amalunga kanye nokuhlangana kwama-cylinder liners, kanye nezingxenye zepulasitiki nezingilazi zokunamathisela - izibani, izibani, ama-hatches, ama-brake lights.
I-Anaerobic sealant
Ama-anaerobic sealants ahlanganisa into eqina lapho ithintana nezindawo zensimbi ezikhaleni eziwumngcingo lapho umoya-mpilo wasemkhathini ungangeni khona. Ngakho-ke, ukuze ukwakheka ku-polymerize, kuyadingeka ukuxhuma ngokuqinile izindawo ezingaphezulu zezingxenye.
Izinzuzo zezingoma ze-anaerobic zihlanganisa ukumelana okuphezulu kwendawo yamakhemikhali anolaka, ukudlidliza, ukwehla kwengcindezi namazinga okushisa. Ukwakheka kuphinde kuvimbele ukugqwala, i-oxidation, igesi nokuvuza kwe-liquid.
Njengobubi bezinto ezibonakalayo, umuntu angabiza ukugcwaliswa kwezikhala ezincane kusuka ku-0,05 kuya ku-0,5 mm. I-activator izodingeka ukuze wenze i-polymerize ukwakheka ezindaweni ezingezona ezensimbi noma emazingeni okushisa aphansi.
Ububanzi bama-anaerobic sealants wukuvala, ukulungisa kanye nokuvala amalunga anentambo nama-flanged, izingxenye ezingamacylindrical namaweld.
I-synthetic sealant
Ama-synthetic sealants ayinto emisha engakatholi ukuthandwa okuningi phakathi konjiniyela bezimoto nabashayeli bezimoto. Nokho, le nto inezinzuzo eziningi:
Ukunwebeka okuphezulu.
Ukumelana nomswakama ophezulu, i-ultraviolet, ukulimala komshini.
Izakhiwo zokunamathela eziphezulu, ezigwema ukwelashwa kwangaphambili kwendawo ngaphambi kokusebenzisa i-sealant.
Ukusebenziseka kalula.
Ukusebenza okuningi nokuhlukahluka.
Abanye omakhenikha bezimoto nabathandi bezimoto bathi ukuguquguquka kwayo kuhambisana nobubi bento. Abantu abaningi bakhetha ama-sealant anemininingwane emincane eklanyelwe izakhi ezithile kanye nezingxenye zemoto.
I-polyurethane sealant
Amabhondi ahlukene futhi akhiqizwa ezinhlobonhlobo zemibala, okuvumela ukuthi ukhethe umthunzi wokulungiswa endaweni ephawulekayo. Ama-polyurethane compounds asetshenziswa njengezinsimbi zokunamathisela amafasitelana emoto, ukulungisa izibani, ukuvala ama-seams, kanye nokuqeda izikhala ezingxenyeni zomzimba.
lokushisa sealant
Isetshenziselwa zonke izingxenye zenjini nezinye izingxenye. Kudalwa izingxube ezikwazi ukumelana nokushisa okufika ku-3500 degrees. Kodwa ukulungisa izingxenye zegumbi lenjini, kwanele ukumelana nama-degree angu-2000.
Izindawo zokusetshenziswa kwama-autosealants
Kuye ngenhloso, umkhiqizo usetshenziswa njenge-sealant:
izibani zemoto. Ikuvumela ukuthi ubuyisele ukucinana kwama-optics uma kwenzeka umonakalo noma ukushintshwa kwengilazi yesibani.
amafasitela emoto. Indlela engcono kakhulu yokunamathisela i-windshield yengilazi yemoto nezinye izindlela zokuthutha;
injini yemoto. Indlela engcono kakhulu yokuqinisekisa ukuphepha kwezinto zesakhiwo seyunithi yamandla. Zisetshenziswa uma zishintsha iphampu, ukuze zivale ikhava ye-valve kanye ne-pan yokudlulisela;
amathayi ezimoto namadiski. Isiza ezimeni eziphuthumayo, i.e. zokubhoboza kanye nokulimala kwamashubhu namathayi angenamashubhu. Ikuvumela ukuthi wenze ukulungisa ngokushesha emgwaqweni;
i-air conditioner yemoto. Akusizi kuphela ukuqeda, kodwa futhi ukuvimbela ukuvuza kwefriji, ngakho-ke kuvame ukusetshenziswa njenge-prophylactic;
izimoto seams. Isetshenziselwa ukulungiswa komzimba - ukuvala i-seams ye-hood, i-trunk, phansi, iminyango.
ukuvala intambo. Amakhompiyutha anemicu avimbela ukuvuza emapayipini nasezihlalweni zamapayipi. Ihlinzeka ngokulingana kwentambo eqinile ngisho nangaphansi kwengcindezi ephezulu.
Imibandela Yokukhetha I-Sealant
Lapho ukhetha i-sealant, kufanele unake ukuhambisana nezici zayo zobuchwepheshe kanye nezici zokusebenza kwezingxenye.
Ipharamitha ebalulekile yokukhetha i-sealant yizici zezinto ezisebenzayo ekubunjweni komkhiqizo: izinga lokumelana nokucindezela kanye nemithwalo yokudlidliza, ukuqina ngemva kokuqina nokuqina.
Ukuba khona kwe-dispenser kanye nesidingo sesibhamu se-caulking nakho kudlala indima ekukhethweni kwe-agent caulking.
Uma i-compound yokuvala ibonakala ngokungahambisani nokushisa okuphezulu, akufanele isetshenziswe ezingxenyeni zenjini.
Asikho isidingo sokuthenga ama-sealants kumaphakheji amakhulu wevolumu: akufanelekile ukugcina i-sealant esele, njengoba izolahlekelwa izakhiwo zayo ngokuhamba kwesikhathi.
Abashayeli bezimoto nabo bayanaka ukuthi le nto yoma isikhathi esingakanani. Njengoba sekushiwo ngenhla, izingoma ze-anaerobic ziba lukhuni kuphela lapho kungabikho ukuxhumana nomoya-mpilo. Lokhu kusho ukuthi umshayeli unesikhathi sokuzola futhi ngaphandle kokushesha ukusebenzisa i-ejenti ebusweni bezingxenye futhi azixhume ngaphandle kokwesaba ukuthi into izoba lukhuni ngaphambi kwesikhathi.
Ama-Silicone sealants aphulukisa kungakapheli imizuzu eyi-10, kepha awadingi ukunemba okukhethekile kwesicelo, ngakho-ke angasetshenziswa ngisho nabashayeli abangenalwazi. Ngakolunye uhlangothi, ukusetshenziswa kwemikhiqizo ye-silicone kufanelekile uma kuvalwa izikhala ezijulile, kuyilapho ama-anaerobic compounds akwazi ukugcwalisa ukungahambi kahle ngokujula okungaphezu kuka-0,5 cm.
