Nug tus kws kho tsheb lossis tus tsim lub nkoj txog kev vibration, thiab lawv yuav qhia koj tias nws yog tus neeg tua neeg uas ntsiag to ntawm cov ntsaws ruaj ruaj. Screws loosen, welds qaug zog, thiab feem ntau tapes maj mam sib nrug. Tab sis butyl sealing daim kab xev? Qhov nplaum, grey, putty-zoo li yob koj yuav luag saib ntawm lub khw muag khoom kho vajtse? Nws tsis yog tsuas yog muaj sia nyob vibration- nws ua tau zoo dua vim nws.
Cia kuv muab piv txwv tiag tiag rau koj. Xyoo tas los, kuv tau pab ib tug phooj ywg kaw lub ru tsev seam ntawm lub tsheb thauj khoom qub. Cov hlau panels flexed tas li, tshwj xeeb tshaj yog nyob rau hauv txoj kev bumpy. Peb siv cov qauv roj hmab foob thaum xub thawj. Tsis pub dhau ob lub lis piam, nws tau nyem tawm, tawm hauv qhov sib txawv uas xuav ntawm txoj kev loj. Tom qab ntawd peb hloov mus rau butyl sealing daim kab xev. Peb nias nws mus rau hauv qhov zawj, bolted lub panels ua ke, thiab tsis nco qab txog nws. Peb lub hlis tom qab, tom qab ntau txhiab mais ntawm cov pob zeb thiab pob zeb, cov seam tseem qhuav. Tsis tawg. Tsis muaj oozing. Tsuas yog ib qho ruaj khov, me ntsis squided hlaws uas tau ua nws tus kheej nruj dua rau hauv cov xov ntawm cov bolts.
Yog li dab tsi tshwm sim? Tsis zoo li cov nplaum nplaum lossis cov nplaum nplaum, butyl nyob twj ywm yas mus tas li. Xav tias nws yog tuab heev, tsis yog - cov av nplaum qhuav. Thaum vibration hits, daim kab xev tsis tiv thaiv los ntawm hardening - nws absorbs cov lus tsa suab los ntawm sab hauv molecular slippage. Qhov ntawd suab zoo nkauj, tab sis tiag tiag nws txhais tau hais tias cov khoom yields txaus kom tiv tauj, ces bounces rov qab. Nyob rau hauv cov ntsiab lus kev, nws siab damping coefficient hloov shaking zog mus rau hauv me ntsis ntawm tshav kub es tsis txhob tawg daim ntawv cog lus. Thiab lub tack? Nws tsis yog kua nplaum nto. Butyl yeej ntws mus rau hauv lub qhov me me thiab khawb thaum lub sij hawm, yog li txawm tias cov khoom rattle sab - rau - sab, lub foob tsis plam nws tuav.
Marine mechanics tau paub qhov no rau ntau xyoo lawm. Ntawm lub nkoj nkoj lub lawj cov khoom siv-winches, chainplates, rail bases- kev vibration los ntawm lub cav diesel thiab nthwv dej yuav ua kom puas polyurethane sealants hauv ib lub caij. Butyl daim kab xev? Nws kav tsib xyoos lossis ntau dua. Qhov zais cia yog nws cov dej txias. Raws li qhov qis qis -qib co, daim kab xev maj mam ua raws txhua txoj haujlwm tshiab ntawm lub fastener. Es tsis txhob tearing, nws redistributes siab. Koj tuaj yeem tshem lub ntsia liaj qhov rooj ob xyoos tom qab, thiab daim kab xev yuav tau tsim ib lub gasket zoo meej nyob ib ncig ntawm lub shank.
Tau kawg, tsis yog txhua daim kab xev butyl sib npaug. Cov khoom pheej yig nrog cov khoom siv ntau dhau crumbled. Tab sis daim kab xev zoo nrog 30% lossis ntau dua polyisobutylene roj hmab? Nov yog koj lub vibration fighter. Nrhiav ib lub hnab nqa khoom- nws tiv thaiv extrusion nyob rau hauv hnyav loads. Thiab tsis txhob crank lub bolts mus rau siab torque. Tes- nruj ntxiv rau peb lub hlis twg tig ua rau chav kab xev ua pa.
Yog li lwm zaus ib tug neeg qhia rau koj tias tsis muaj sealant tuav tuav, muab lawv ib yob ntawm butyl. Nws yuav tsis tawg zoo li epoxy. Nws yuav tsis qhuav zoo li silicone. Nws tsuas yog zaum ntawd, noj txhua lub pob, thiab ntsiag to ua nws txoj haujlwm. Kev vibration? Qhov ntawd yog qhov nws tau ua rau.
