Roj hmab sealing strips yog qhov tseem ceeb sealing suav hauv kev lag luam thiab pej xeem kev lag luam. Lawv cov kev ua tau zoo cuam tshuam cov kev sib khi, ua kom ruaj khov, thiab zog ua haujlwm ntawm cov khoom. Kev xaiv kom tsim nyog, teeb tsa, thiab saib xyuas cov roj hmab sealing strips tsis tsuas yog ncua lawv txoj kev pabcuam lub neej tab sis kuj txhim kho kev ntseeg tau yooj yim. Cov kab lus no qhia txog cov ntsiab lus tseem ceeb ntawm cov roj hmab sawb daim ntawv thov, suav nrog kev xaiv cov khoom, cov qauv kev teeb tsa, kev ntsuas ntau yam.
I. Cov ntsiab lus tseem ceeb hauv cov khoom xaiv
Cov kev ua tau zoo ntawm cov roj hmab sealing strips yog ze rau lawv cov khoom siv hauv paus, thiab cov ntawv thov sib txawv yuav tsum muaj cov roj hmab sib txawv. Cov Khoom Siv Roj Hmab Xws Li:
1.ethylene diene monomer (EPDM): Cov huab cua zoo ua rau nws haum rau kev siv sab nraum zoov xws li lub qhov rooj thiab lub qhov rai safrofs. Nws zoo siab tiv thaiv UV rays, ozone, thiab huab cua kub hloov pauv.
2.nitrile butadiene roj hmab (NBR): Zoo heev cov roj ua luam ua rau nws dav siv hauv cov ntawv thov xws li roj cav thiab cov roj av.
3.Silicone Roj Hmab (VMQ): Muaj cov khoom siv kub tsawg thiab tsawg dua 60 degree), xws li qhov cub ntsaws thiab cov tub yees khoom.
4.Chloroprene Roj Hmab (CR): Muaj cov tshuaj tiv thaiv zoo heev thiab siv tau siv cov raj tshuaj lom neeg lossis dej noo noo.
Thaum xaiv, xav txog kev sib txawv, ntau yam kev kub, thiab tus nqi {- ua tau zoo rau cov khoom siv tau zoo rau daim ntawv thov kev thov.
Ii. Cov lus qhia cov lus qhia thiab kev ceev faj
Qhov zoo tshaj ntawm cov roj hmab foob txhim kho ncaj qha cuam tshuam nws cov kev sib khi ua tau zoo. Cov hauv qab no yog cov ntsiab lus tseem ceeb:
1.Surge npaj: ua ntej kev teeb tsa, ntxuav cov mating saum npoo kom tshem tawm cov roj, plua plav, thiab burrs. Yog tias tsim nyog, so nrog dej cawv lossis tshuaj ntxuav kom paub meej tias tsis muaj qhov cuam tshuam uas yuav cuam tshuam rau cov adhesion.
2. Tshem Tej Qhov Muag: Tus ntoo khaub lig {1} SeemTal Qhov ntev ntawm lub foob yuav tsum tau phim lub qhov mounting. Kev siv zog yuav ua rau teeb tsa tsis ua haujlwm, thaum lub sij hawm overLoosening yuav ua rau cov khoob. Nws raug nquahu kom tso cai rau 5% -10% compression margin kom ntseeg tau tias yog cov cim zoo.
3.Txhua kev teeb tsa cov kev taw qhia: rau cov kev qhia sib tw (xws li cov ntawv qhia Grooves), ua kom cov chaw ua haujlwm zoo (piv txwv li, cov hmoov av di ncauj ntsej muag sab nraud).
4.Toors: Siv cov menyuam yaus muaj siab xav siv lossis roj hmab rauj rau kev thov kom tsis txhob muaj zog tshaj - Extrusion uas tuaj yeem ua rau cov khoom puas. Rau cov ntsaws ruaj ruaj, nruab hauv cov ntu thiab kho lawv maj.
III. Cov teeb meem thiab kev daws teeb meem
1.Txoj kev laus laus thiab kev tawg: Qhov no feem ntau tshwm sim los ntawm lub sijhawm ntev ntev rau UV rays, ozone, lossis huab cua sov. Cov kev daws teeb meem suav nrog kev xaiv huab cua - Cov ntaub ntawv resistant (xws li EPDM), ntxiv cov khoom tiv thaiv kab mob, lossis hloov cov txheej txheem.
2. puab txheej teeb tsa: Tom qab lub ntev compression, ntsaws ruaj ruaj uas poob lawv lub resilience, ua kom xau. Qhov no tuaj yeem hais los ntawm kev ua kom zoo dua cov khoom siv (piv txwv, ntxiv cov pa roj dub) lossis luv luv cov kev saib xyuas.
3.Detachment lossis Misalignment: Qhov no yog ib qho muaj nrog cov nplaum - borded ntsaws ruaj ruaj. Nco ntsoov tias cov nplaum tau sib xws nrog lub substrate thiab zam kev cuam tshuam sab nraud sab nraud thaum lub sijhawm kho.
IV. Kev Ua Haujlwm Zoo thiab Kev Pom Zoo Txij Nkawm
1. Kev tshuaj xyuas cov ntsaws ruaj ruaj rau kev hnav, deformation, thiab cov nplaum txhua txhua peb hlis, thiab sai sai {1} Taug kev ib qhov xoob.
2. Siv cov yeeb yaj kiab (xws li cov ntsaws ruaj ruaj), thov cov ntsaws ruaj ruaj), thov cov roj silicone
3.Ulgre daws: Rau cov ntawv thov xav tau (xws li lub tshuab nqus tsev), muaj cov ntsaws ruaj ruaj (piv txwv li, roj hmab ncej) tuaj yeem siv rau kev sib npaug yooj yim thiab rigidity.
Tag
Txawm hais tias cov ntaub qhwv roj hmab yog cov khoom xyaw me, lawv yog cov ntsiab lus tseem ceeb hauv kev ua kom ncaj qha kev ua haujlwm. Los ntawm kev xaiv science, qauv teeb tsa, thiab kev saib xyuas sib txawv, lawv cov txiaj ntsig tuaj yeem ua kom tiav thiab ntev} cov nqi txo. Kev xyaum engineering, cov tswv yim yuav tsum tau hloov kho raws li cov kev ua haujlwm tshwj xeeb kom ntseeg tau tias qhov kev ruaj ntseg thiab kev ntseeg tau ntawm kev sib khi.
