Ukuhlola ama-sealant esistimu yokukhipha umoya wezimoto
Okuqukethwe
Ngabe i-muffler sealant isebenza kanjani futhi isetshenziswa kuphi?
Ama-sealant e-exhaust ezimoto avame ukubizwa ngokuthi "amasimende". Ngaphezu kwalokho, igama elithi "usimende" libizwa hhayi kuphela phakathi kwabashayeli njenge-slang. Abanye abakhiqizi bama-muffler sealant basebenzisa leli gama emaphaketheni abo, hhayi ngezinjongo zokuthengisa.
Ukufana kwama-sealant anosimende kunencazelo yangempela, esetshenzisiwe, kanye nekhemikhali. Cishe wonke ama-sealant ezimoto ayizinhlobo ezahlukahlukene zama-polymer. Futhi usimende wokulungisa isistimu yokukhipha insimbi iyi-polymer enokuqukethwe okuphezulu kwama-silicates. I-silicon, njengesisekelo sazo zonke izinhlanganisela ze-silicate, futhi iyisici samakhemikhali esiyinhloko sikasimende wokwakha ovamile.
Ukufana kwesibili kusesimisweni esijwayelekile sokusebenza. Ama-sealants, ngemva kokufakwa phezulu ukuze aphathwe, aqine, njengamasimende.
Ngenxa yokuqukethwe okuningi kwezinhlanganisela ze-ceramic, ama-muffler sealant anokuqina okuphezulu kokushisa. Ngokwesilinganiso, ngaphambi kokuqala kwezinqubo ezilimazayo, izingoma eziningi zale njongo zingashiswa kumazinga okushisa angaphezu kuka-1000 ° C.
Ezimweni eziningi, ama-muffler sealants asetshenziswa ekuxhumekeni kwesistimu yokukhipha umoya ukuze kuthuthukiswe ukuqina. Kancane kancane - njengethuluzi lokulungisa. Bafaka amaphutha amancane: imifantu emincane, ukushisa kwendawo, izindawo zokuxhuma ezilimele zesistimu yokukhipha umoya.
Ngemuva kokuphulukisa, ama-sealants akha ungqimba oluqinile lwe-polymer, olunobunzima obuphezulu futhi ngesikhathi esifanayo ukuqina okuthile (i-polymer ingakwazi ukumelana nemithwalo encane yokudlidliza kanye nokunyakaza okuncane ngaphandle kokulimala), kanye nokumelana nokushisa. Yile sethi yezimfanelo ezidingekayo ukuze uvale uhlelo lwe-exhaust.
Uhlolojikelele olufushane lwemikhiqizo edumile emakethe
Ake sicabangele ama-sealant amaningana ama-mufflers adumile eRussia.
- I-Liqui Moly yokulungisa umshini wokukhipha umoya. Enye yama-sealant ebiza kakhulu futhi ephumelelayo yamalunga okushisa aphezulu. Ikhiqizwa ngamashubhu epulasitiki anomthamo we-200 gr. Ibiza cishe ama-ruble angama-400. Indawo eyinhloko yohlelo lokusebenza yizinhlelo zokuqeda izimoto. Kodwa futhi ingasetshenziselwa ezinye izinhlanganisela ezisebenza emazingeni okushisa aphezulu. Isetshenziswa engxenyeni evuzayo ye-exhaust tract. Ukuqina okuyisisekelo kwenzeka phakathi kwemizuzu eyi-15-20 injini ingasebenzi. Ngaphandle kokushisisa uhlelo, i-sealant izokwelapheka ngokugcwele cishe amahora ayi-12.
- I-ABRO Exhaust System Sealer Cement. Ikhambi lesibili ethandwa kakhulu eRussia. Intengo ye-tube enevolumu ye-170 amagremu ingama-ruble angama-200-250. Isici esihlukile sika-Abro usimende yikhono lokudala amapheshana aqinile futhi aqinile. Kuqinisekisiwe ukwenza i-polymerize ngesethi yobulukhuni obugcwele, obalwe ngogqinsi olufika ku-6 mm. Iyoma ibe sesimeni esisebenzisekayo emizuzwini engu-20 injini ingasebenzi. Ngemuva kwamahora ama-4, ithola amandla amakhulu.
- I-Bosal Muffler Cement. I-sealant engabizi, kodwa esebenza kahle kakhulu yokulungisa amasistimu wokukhipha umoya. I-tube yamagremu angu-190 ibiza cishe ama-ruble angu-150. Ngokuyinhloko isetshenziswa njenge-filler ku-voids yokuxhuma ye-exhaust tract. Isetshenziswa emalungeni ezakhi zomuntu ngamunye nangaphansi kwama-clamps. Ngemva kokoma, yenza ungqimba lukasimende oluqinile olungashi.
Kunamanye ama-sealant ambalwa e-exhaust emakethe. Zonke zisebenza kahle. Futhi ngokujwayelekile, umthetho uyasebenza: intengo ephezulu, uxhumo olunamandla futhi olungcono luzohlukaniswa noma umonakalo uzovalwa.
Ukubuyekezwa kwabashayeli bezimoto
Iningi labashayeli bezimoto likhuluma kahle cishe ngawo wonke ama-sealant okulungiswa kwamasistimu e-exhaust. Lawa ma-sealants avame ukusetshenziswa ezimweni ezimbili: ukufakwa kwezakhi zomuntu ngamunye ze-exhaust tract nge-insulation eyengeziwe yamalunga, noma ukulungiswa komonakalo omncane.
Ukuphila kwe-sealant kuncike enanini elikhulu lezici. Ngakho-ke, akunakwenzeka ukusho noma yisiphi isikhawu sesikhathi lapho ukwakheka kungeke kugoqe. Kodwa ngokuvamile, uma izimo zokufaka zihlangene, i-sealant ebekwe ekuhlanganyeleni izohlala kuze kube yilapho ukulungiswa okulandelayo kwesistimu, futhi ama-patches kwezinye izimo ahlala iminyaka emi-5.
Izibuyekezo ezingezinhle zivame ukuhlotshaniswa nokusetshenziswa kabi kwezimali. Isibonelo, uma uxhumano lungalungiswanga kahle (ukugqwala, i-soot kanye ne-oily deposits ayisusiwe), i-sealant ngeke ihambisane kahle nezindawo, futhi ngenxa yalokho, ngemva kwesikhathi esifushane, izoqala ukudilika nokuwa. . Futhi, ngaphambi kokuqala ukusebenza okugcwele kwemoto, kuyadingeka ukunikeza isikhathi sokwakheka kwe-polymerization ephelele.
Ngosizo lwama-sealant wezinhlelo zokukhipha umoya, akunconywa ukulungisa imifantu ezindaweni ezingase zibe nokucindezeleka kanye nokushiswa kwezinto ezigqwalile kakhulu nezishile ezinobukhulu bensimbi obuncane obubucayi.
