Test lub tsheb tso qhov system sealants

Lub muffler sealant ua haujlwm li cas thiab nws siv qhov twg?
Automotive exhaust sealants feem ntau hu ua "cements". Ntxiv mus, lo lus "cement" yog hais tsis tau tsuas yog cov neeg tsav tsheb raws li slang. Qee cov tuam txhab lag luam ntawm muffler sealants siv lo lus no ntawm lawv cov ntim, thiab tsis yog rau kev lag luam.
Qhov zoo sib xws ntawm sealants nrog cements muaj ob qho tib si tiag tiag, siv lub ntsiab lus, thiab tshuaj lom neeg. Yuav luag tag nrho cov tsheb sealants yog ntau hom polymers. Exhaust system kho cement yog ib qho polymer nrog cov ntsiab lus siab ntawm silicates. Silicon, raws li lub hauv paus ntawm tag nrho cov silicate tebchaw, kuj yog cov tshuaj tseem ceeb ntawm cov pa tsev cement.
Qhov thib ob zoo sib xws nyob rau hauv lub hauv paus ntsiab lus ntawm kev ua haujlwm. Sealants, tom qab siv rau saum npoo los kho, tawv, zoo li cements.
Vim muaj ntau cov ntsiab lus ntawm cov khoom siv ceramic, muffler sealants muaj thermal stability. Qhov nruab nrab, ua ntej qhov pib ntawm kev puas tsuaj, feem ntau cov ntsiab lus ntawm lub hom phiaj no tuaj yeem ua rau kub siab tshaj 1000 ° C.
Feem ntau, muffler sealants yog siv nyob rau hauv cov pa system sib txuas los txhim kho nruj. Tsis tshua muaj - raws li cov cuab yeej kho. Lawv cement me me tsis xws luag: tawg me me, burnouts hauv zos, puas cov ntsiab lus ntawm cov pa system.
Tom qab kho, cov sealants tsim ib cov khoom polymer txheej, uas muaj siab hardness thiab nyob rau tib lub sij hawm ib co elasticity (polymer tuaj yeem tiv taus me me vibration loads thiab micro-tsav tsis muaj kev puas tsuaj), nrog rau cov cua sov. Nws yog cov txheej txheem zoo no uas yuav tsum tau muab khi rau qhov tso pa tawm.
Cov ntsiab lus luv luv ntawm cov khoom nrov ntawm lub khw
Cia peb xav txog ntau yam sealants rau mufflers uas nrov nyob rau hauv Russia.
- Liqui Moly Exhaust kho muab tshuaj txhuam. Ib qho ntawm cov khoom kim tshaj plaws thiab zoo sealants rau cov pob qij txha kub. Ua nyob rau hauv cov yas raj nrog ib ntim ntawm 200 gr. Nws raug nqi txog 400 rubles. Qhov chaw tseem ceeb ntawm daim ntawv thov yog lub tshuab tso pa ntawm lub tsheb. Tab sis nws kuj tuaj yeem siv rau lwm cov tebchaw ua haujlwm ntawm qhov kub thiab txias. Nws yog siv rau qhov seem ntawm lub qhov tso pa tawm. Thawj hardening tshwm sim nyob rau hauv 15-20 feeb ntawm lub cav idling. Yog tsis muaj cua sov lub cev, lub sealant yuav kho tag nrho hauv li 12 teev.
- ABRO Exhaust System Sealer Cement. Qhov thib ob nrov tshuaj nyob rau hauv Russia. Tus nqi rau ib lub raj nrog lub ntim ntawm 170 grams yog 200-250 rubles. Ib qho tshwj xeeb ntawm Abro cement yog lub peev xwm los tsim cov thaj ua kom tuab thiab ruaj khov. Nws yog guaranteed rau polymerize nrog ib tug tag nrho, xam hardness nrog ib tug txheej thickness txog li 6 hli. dries mus rau qhov kev pab cuam nyob rau hauv 20 feeb ntawm lub cav idling. Tom qab 4 teev, nws nce siab tshaj plaws.
- Bosal Muffler Cement. Pheej yig, tab sis zoo heev sealant rau kev kho lub tshuab pa. Ib lub raj ntawm 190 grams raug nqi txog 150 rubles. Nws yog tsuas yog siv los ua ib tug muab tub lim nyob rau hauv qhov sib txuas voids ntawm lub tso pa tawm. Nws yog siv rau cov pob qij txha ntawm tus kheej cov ntsiab lus thiab nyob rau hauv lub clamps. Tom qab ziab, nws tsim ib txheej cement nyuaj uas tsis hlawv tawm.
Muaj ob peb lwm cov pa system sealants ntawm lub khw. Tag nrho cov ntawm lawv muaj zoo efficiency. Thiab feem ntau, txoj cai ua haujlwm: tus nqi siab dua, qhov muaj zog thiab zoo dua qhov kev sib txuas yuav raug cais tawm lossis kev puas tsuaj yuav raug kaw.
Kev tshuaj xyuas cov neeg tsav tsheb
Cov neeg tsav tsheb feem ntau hais lus zoo ntawm yuav luag tag nrho cov sealants rau kev kho lub tshuab tso pa. Cov sealants no feem ntau yog siv nyob rau hauv ob rooj plaub: lub installation ntawm ib tug neeg lub ntsiab ntawm lub tso pa ib ntsuj av tau ntxiv rwb thaiv tsev ntawm cov pob qij txha, los yog kho me ntsis kev puas tsuaj.
Lub neej ntev ntawm lub sealant nyob ntawm ntau yam. Yog li ntawd, nws yog tsis yooj yim sua rau npe ib lub sij hawm luv luv lub sij hawm uas lub composition yuav tsis vau. Tab sis feem ntau, yog tias cov teeb meem kev teeb tsa tau ua tiav, tom qab ntawd cov sealant tau muab tso rau hauv qhov sib koom ua ke yuav kav mus txog rau qhov kev kho tom ntej ntawm lub kaw lus, thiab qee zaum cov thaj ua rau thaj kav ntev txog 5 xyoos.
Kev tshuaj xyuas tsis zoo feem ntau cuam tshuam nrog kev siv nyiaj tsis raug. Piv txwv li, yog tias qhov kev sib txuas tau npaj tsis zoo (xeb, cov pob zeb thiab cov roj av tsis raug tshem tawm), ces lub sealant yuav tsis ua raws li qhov zoo ntawm qhov chaw, thiab vim li ntawd, tom qab lub sijhawm luv luv, nws yuav pib tawg thiab poob tawm. . Tsis tas li ntawd, ua ntej pib ua haujlwm tag nrho ntawm lub tsheb, nws yog ib qho tsim nyog yuav tsum muab lub sijhawm sib xyaw ua kom tiav polymerization.
Nrog kev pab los ntawm sealants rau lub tshuab tso pa tawm, nws tsis pom zoo kom kho cov kab nrib pleb hauv cov cheeb tsam uas muaj kev ntxhov siab thiab kub hnyiab ntawm cov khoom hnyav hnyav thiab kub hnyiab nrog cov hlau hnyav me me.
