1. Distinguishing Butyl daim kab xev los ntawm tsw
Ib txoj hauv kev yooj yim tshaj plaws los txheeb xyuas qhov siab - zoo butyl daim kab xev yog los ntawm nws cov ntxhiab tsw. Daim kab xev butyl tiag, ua los ntawm cov khoom siv roj hmab siab zoo, feem ntau muaj cov ntxhiab tsw nruab nrab lossis tej zaum yuav muaj qhov muag heev, tsis yog - ntxhiab tsw. Qhov no yog vim nws muaj tsawg heev volatile chemicals los yog additives. Hauv qhov sib piv, qis- zoo butyl tapes feem ntau muaj emulsions lossis asphalt- cov khoom siv, uas ua rau muaj qhov sib txawv, muaj zog tsw. Cov qauv pheej yig dua ntawm butyl daim kab xev no tuaj yeem tso tawm qhov tsis xis nyob, oily lossis tar - zoo li tsis hnov tsw, qhia txog kev siv cov khoom xyaw tsis zoo.
Yog vim li cas Smell Matters
Lub xub ntiag ntawm cov ntxhiab tsw muaj zog hauv butyl daim kab xev tuaj yeem yog lub cim qhia tias cov chaw tsim khoom tau siv cov khoom siv ntxiv xws li asphalt, uas txo cov nqi tsim khoom tab sis cuam tshuam cov kab xev tag nrho. Asphalt-raws li daim kab xev kuj tseem tsis tuaj yeem muab tib theem ntawm kev tiv thaiv dej, tiv thaiv tshav kub, thiab ua haujlwm ntev raws li cov ntaub nplaum butyl roj hmab tiag. Raws li cov ntaub ntawv no zoo li tawg sai dua nyob rau hauv ib puag ncig kev ntxhov siab (xws li UV rays thiab kub kub), daim kab xev lub neej ntev thiab kev sib khi muaj peev xwm txo qis.
Yuav Ua Li Cas Ntsuas Qhov Ncauj
Thaum muas butyl daim kab xev, tshwj xeeb tshaj yog nyob rau hauv ntau, nws yog ib lub tswv yim zoo los tshuaj xyuas cov ntxhiab tsw ua ntej txiav txim siab zaum kawg. Tsuas yog qhib lub ntim los yog nqa ib daim kab xev me me thiab tsw qab. Yog hais tias daim kab xev emit ib tug muaj zog, tsis kaj siab tsw, nws yuav ua tau nrog pheej yig dua cov ntaub ntawv xws li asphalt los yog emulsions. High - zoo butyl tapes, ntawm qhov tod tes, yuav muaj me ntsis kom tsis muaj ntxhiab tsw, lees tias lawv yog tsim los ntawm cov roj hmab ntshiab butyl.
2. Distinguishing Butyl daim kab xev los ntawm xim
Lwm qhov tseem ceeb los tshuaj xyuas thaum ntsuas cov kab xev butyl yog nws cov xim. Qhov tseeb butyl daim kab xev feem ntau muaj lub ntsej muag dawb nrog lub ntsej muag daj me ntsis. Qhov no yog vim lub ntuj xim ntawm butyl roj hmab, uas yog siv los ua cov khoom tseem ceeb nyob rau hauv siab - zoo tapes. Yog tias koj ntsib ib daim kab xev uas yog grey los yog dub, nws yog ib qho kev qhia tias cov chaw tsim khoom tau ntxiv asphalt lossis lwm cov khoom siv pheej yig los txo cov nqi tsim khoom.
Lub luag haujlwm ntawm Xim hauv Kev Zoo
Cov xim ntawm butyl daim kab xev ua hauj lwm ua ib qho tseem ceeb qhov muag pom ntawm nws muaj pes tsawg leeg. High - zoo butyl daim kab xev feem ntau yog opaque thiab lub teeb nyob rau hauv cov xim, uas tso cai rau nws mus muab seamlessly nrog rau feem ntau nto yam tsis tau tsim ib tug unsightly contrast. Cov kab xev uas pom grey lossis dub feem ntau yog cov khoom lag luam tsis zoo, vim lawv feem ntau muaj qis -qib additives xws li asphalt lossis lwm hom emulsion. Cov additives no tsis tsuas yog hloov xim tab sis kuj tuaj yeem cuam tshuam rau daim kab xev kev ua tau zoo, ua rau nws yooj yim rau kev tawg, degradation, thiab txo adhesion thaum lub sij hawm.
Yuav kuaj Xim li cas
Thaum ntsuas butyl daim kab xev los ntawm cov xim, muab piv nrog qhov xav tau milky dawb tsos ntawm siab - daim kab xev zoo. Yog tias daim kab xev yog grey tsaus lossis dub, nws yog ib qho tseem ceeb uas yuav tsum tau ceev faj, vim cov no yog cov cim qhia tias nws yuav muaj cov fillers uas txo nws cov txiaj ntsig. Koj tuaj yeem thov cov qauv ntawm cov khoom los xyuas cov xim ua ntej yog tias koj tab tom yuav daim kab xev los ntawm tus neeg muag khoom lossis khw hauv online.
3. Distinguish Butyl daim kab xev los ntawm viscosity
Viscosity, los yog lub thickness thiab stickiness ntawm daim kab xev, yog lwm yam uas yuav pab tau txiav txim nws zoo. Daim kab xev butyl tiag tiag feem ntau muaj qhov nruab nrab - mus rau - qis qis pib. Qhov no txhais tau tias nws yog me ntsis tacky tab sis tsis dhau nplaum. Qhov sib npaug viscosity no ua kom cov ntaub nplaum tuaj yeem siv tau yooj yim yam tsis muaj kev ntxhov siab lossis nyuaj thaum tseem tsim kom muaj kev ruaj ntseg thiab txhim khu kev qha.
Teeb meem nrog High -Viscosity Tapes
Tsawg- zoo butyl tapes, tshwj xeeb tshaj yog cov uas muaj asphalt lossis emulsions, feem ntau muaj cov viscosity ntau dua. Cov kab xev no yuav hnov zoo heev thiab tacky, uas tuaj yeem ua rau kev teeb tsa nyuaj, tshwj xeeb tshaj yog tias koj yuav tsum tau hloov daim kab xev. Nyob rau hauv cov huab cua kub, cov ntaub nplaum no feem ntau yuav ua "ntws" los yog dej ntws, poob lawv cov nplaum nplaum thiab tso dej los yog noo noo kom nkag mus rau hauv.
Tsis tas li ntawd, thaum lub viscosity siab dhau lawm, daim kab xev tuaj yeem ua tsis yooj yim rau kev lis kev cai thiab tej zaum yuav tsim qhov chaw tsis sib xws lossis tsis muaj zog hauv qee qhov chaw. Ntawm qhov tod tes, yog tias qhov viscosity tsawg dhau lawm, daim kab xev yuav tsis muaj qhov tsim nyog adhesion los tsim ib qho kev ruaj ntseg foob, tshwj xeeb tshaj yog nyob rau hauv kev xav tau tej yam kev mob xws li los nag hnyav los yog huab cua kub.
Yuav Ua Li Cas Ntsuas Viscosity
Txhawm rau kuaj cov viscosity ntawm butyl daim kab xev, siv ib qho me me ntawm daim kab xev rau qhov chaw huv, qhuav. Sim nias daim kab xev kom ruaj khov rau hauv qhov chaw thiab saib nws tackiness. Daim kab xev butyl tiag tiag yuav hnov ntxhiab tab sis tsis dhau dhau, thiab nws yuav nyob hauv qhov chaw tsis muaj kev zawv zawg lossis khiav ntau dhau. Hauv qhov sib piv, qis- cov ntaub nplaum zoo nrog cov viscosity siab dua yuav hnov ntxhiab heev thiab tuaj yeem ntws los yog deform yog tias raug tshav kub lossis ya raws.
Yog tias koj tsis paub meej ntawm daim kab xev qhov zoo, nws yog ib lub tswv yim zoo los nug cov khoom specifications los yog thov ib tug qauv mus kuaj nyob rau hauv tiag tiag - ntiaj teb no tej yam kev mob. Zoo - zoo butyl daim kab xev yuav tsum tuav nws daim ntawv, txawm nyob rau hauv siab, thiab nyob ruaj khov nyob rau lub sij hawm.
4. Distinguishing Butyl daim kab xev los ntawm cov ntawv xeem
Tej zaum txoj kev ntseeg siab tshaj plaws ntawm kev txheeb xyuas qhov siab - zoo butyl daim kab xev yog los ntawm kev tshuaj xyuas nws cov ntawv xeem thiab ntawv pov thawj. Zoo-cov tuam txhab tsim khoom feem ntau muab cov ntaub ntawv thib peb- cov ntawv xeem thib peb uas qhia tau tias lawv cov khoom ua raws li cov qauv kev lag luam cuam tshuam. Cov ntawv ceeb toom no ntsuas cov yam ntxwv tseem ceeb xws li UV tsis kam, kev laus ua haujlwm, lub zog tensile, thiab kev ua haujlwm adhesion.
Vim li cas Test Reports tseem ceeb
Cov ntawv xeem muab kev ntsuam xyuas dav dav ntawm daim kab xev kev ua haujlwm dhau sijhawm. Piv txwv li, kev ntsuas UV tiv thaiv qhia tau tias daim kab xev tuav tau li cas nyob rau hauv lub hnub raug lub hnub ntev, thaum kev laus tiv thaiv kev ntsuas ntsuas seb cov kab xev tiv thaiv kev puas tsuaj ntau xyoo. High - zoo butyl tapes raug kuaj nruj kom ntseeg tau tias lawv ua tau raws li cov qauv tsim nyog rau kev siv ntau yam, suav nrog kev tiv thaiv dej thiab kev sib khi.
Hauv qhov sib piv, qis- zoo butyl tapes, feem ntau tsim los ntawm cov chaw ua haujlwm me me lossis cov tuam txhab tsis tau lees paub, yuav tsis muaj qhov thib peb- cov ntaub ntawv xeem dhau los. Yog tias tsis muaj cov ntawv ceeb toom no, nws tsis tuaj yeem lees paub tias daim kab xev puas ua tau raws li cov qauv kev lag luam lossis ua tau raws li tau thov. Cov kab xev uas tsis tau kuaj no feem ntau yuav ua tsis tiav ntxov, ua rau raug nqi kho lossis hloov cov kab.
