Anaerobic sealant yog ib yam khoom siv nyob rau hauv ib puag ncig oxygen-permeable, xws li hlau thiab yas kav, thiab vim nws cov khoom tsis hloov nws cov qauv.
Feem ntau, anaerobic sealant yog siv rau hauv cov tshuab cua sov uas siv hluav taws xob ua lub foob, uas ua rau kev ua haujlwm zoo ntawm lub cev. Vim nws txoj kev ua haujlwm, cov khoom no muab kev sib khi ua tiav ntawm cov welds, sealing ntawm threaded pob qij txha, sealing threads ntawm cov kav dej thiab cov yeeb nkab txuas, nrog rau kho ntau yam cylindrical qhov chaw los ntawm txhua yam khoom.
Anaerobic sealant suav nrog cov tshuaj hauv qab no:
monomers lossis oligomers los ntawm acrylic;
ib txheej ntawm cov tshuaj uas ua haujlwm pib ua haujlwm;
stabilizers;
ntau yam khoom ntxiv xws li thickeners, colorants
Cov khoom muaj xws li cov yam ntxwv tshwj xeeb tau tshwm sim thawj zaug ntawm kev ua lag luam hauv 50s hauv Tebchaws Meskas.
Nyob rau lub sijhawm luv luvLub sij hawm ntawm lub sij hawm, anaerobic sealant tau nrov ntawm ntau tus neeg siv khoom, txij li tsis muaj ib yam khoom tuaj yeem muab kev sib khi zoo ntawm qhov nqaim. Nws tau ntxiv rau hauv qhov sib txawv, qhov uas nws cuam tshuam nrog oxygen, ua rau muaj kev hloov pauv hauv cov khoom xyaw, thiab nws hloov mus rau hauv cov khoom ntom ntom, yog li tiv thaiv cov xov ntawm huab cua thiab lwm yam kev puas tsuaj.
Sab nrauv sealant yuav tsum raug xaiv raws li nws yuav siv. Nyob rau hauv kev xyaum, feem ntau sealants yog siv rau cua sov tshuab raws li ib tug sealant. Nyob rau hauv cov ntaub ntawv no, koj muaj peev xwm yuav ib tug pheej yig tshuaj, vim hais tias qhov kub ntawm kev khiav hauj lwm yuav tsis tshaj 300 thiab -196 degrees Celsius, vim hais tias xws li ib tug kub tswj nyob rau hauv lub cua sov system yog tsis yooj yim sua.
Qhov kev xaiv zoo tshaj plaws nyob rau hauv rooj plaub no yuav yog lub sealant, qhov kub ntawm qhov yuav yog: ntawm - 60 txog +150. Ib tug complex muaj pes tsawg leeg ntawm cov tshuaj muab kev tiv thaiv tiv thaiv acid thiab alkaline puas tsuaj uas yuav tshwm sim nyob rau hauv lub cua sov system, ua tsaug rau qhov no, koj muaj peev xwm xaiv ib tug sealant, thiab koj tsis tas yuav tsom mus rau cov tshuaj twg yuav siv los ua ib tug coolant..
Nyob rau hauv rooj plaub thaum lub anaerobic sealant yog siv los ua lub sealant tsis nyob rau hauv lub cua sov system, tab sis rau sealing cov pob qij txha tom qab vuam, nws yuav tsum tau xaiv los ntawm lwm yam uas yuav tsum tau. Ua ntej ntawm tag nrho cov, cov khoom yuav tsum harden sai dua tom qab daim ntawv thov thiab ntau ruaj khov nyob rau hauv kev sib cuag nrog ib tug tej yam homhlau. Tsis tas li ntawd, thaum xaiv cov sealant, tshwj xeeb yuav tsum tau them rau cov ntsiab lus ntawm cov xim pigments nyob rau hauv nws, qhov no yog vim lub fact tias cov xim ntawm cov khoom thiab cov xim ntawm cov sealant yuav tsum zoo sib xws.
Tsis tas li, tsis txhob hnov qab txog qhov twg cov khoom ntim tau ntim lossis ntim nrog cov sealant yuav siv. Nrog kev pab los ntawm ib co manipulations nrog cov muaj pes tsawg leeg ntawm cov tshuaj, nws muaj peev xwm mus nce nws tiv thaiv alkaline thiab acidic influences. Nyob rau hauv qhov xwm txheej uas cov khoom yuav raug siv nyob rau hauv ib puag ncig kub, ib tug sealant nrog ib tug dav kub thiab kev khiav hauj lwm yuav tsum tau rau qhov no.
Thaum xaiv lub sealant, nws yog ib qho tseem ceeb uas yuav tau xav txog ib puag ncig uas nws yuav siv - rau kev sib khi los yog kev sib khi! Ua ntej ntawm tag nrho cov, lub durability ntawm nws ua hauj lwm thiab kev pab cuam lub neej ntawm cov khoom kho nrog cov tshuaj no yuav nyob ntawm seb qhov no. Nrog rau qhov zoo anaerobic sealant, koj tuaj yeem daws teeb meem ntau yam tsis tas yuav them nyiaj ntau.
