Qhov sib txawv tseem ceeb ntawm kev ua kom adhesion thiab primer yog cov adhesion promoters yog additives rau cov xim los txhawb cov adhesion ntawm cov xim zaj duab xis rau substrate, whereas adhesion primers yog dilute cov kev daws teeb meem los khaws cov nto ntawm cov khoom uas muaj bonded nyob rau hauv lub substrate. tom qab theem.
Adhesion txhawb nqa thiab adhesion primers yog cov khoom tseem ceeb hauv cov xim thiab txheej.
Adhesion Promoter yog dab tsi?
Tus adhesion txhawb nqa yog ib qho ntxiv rau cov xim uas muaj txiaj ntsig hauv kev txhawb nqa cov adhesion ntawm zaj duab xis rau substrate. Adhesion tuaj yeem piav qhia raws li kev tiv thaiv ntawm cov txheej txheem kom raug tshem tawm ntawm lub substrate. Tus neeg txhawb nqa adhesion muaj kev sib raug zoo rau lub substrate thiab cov txheej txheej thiab tuaj yeem tsim kev sib txuas ruaj khov thiab ruaj khov.
Qhov tsis muaj adhesion txhawb nqa feem ntau tuaj yeem ua rau cov khoom ntawm cov txheej txheem tsis txaus kom ua tau raws li qhov kawg ntawm kev ua haujlwm ntawm cov xim. Yog li ntawd, adhesion thiab adhesive zog yog ib qho tseem ceeb ua ke ntawm ntau yam ntawm cov ntaub ntawv xim thiab substrate. Cov yam tseem ceeb no suav nrog cov tshuab adhesion, lub cev mechanisms ntawm qib molecular ntawm kev sib tshuam, thermodynamic mechanisms, thiab lwm yam.
Feem ntau, tus neeg txhawb nqa adhesion tuaj yeem txhim kho zaj duab xis adhesion los ntawm nws cov affinity rau substrate thiab cov kua txheej. Ntxiv mus, ntub cov kua txheej rau lub substrate kuj yog ib qho tseem ceeb. Txawm li cas los xij, qhov zoo tshaj plaws adhesion kuj tseem nyob ntawm cov yam ntxwv xws li xim tsim, daim ntawv thov, hom nto thiab nws cov khoom, kev npaj nto, thiab lwm yam.
Adhesion Primer yog dab tsi?
Ib adhesion primer yog ib qho kev daws teeb meem ntawm cov nplaum hauv cov kuab tshuaj organic. Peb tuaj yeem siv qhov kev daws teeb meem no rau kev sib txuas uas tsim cov yeeb yaj kiab qhuav nrog lub thickness ntawm 0.0015 hli. Ntxiv mus, cov roj-raws li primer yuav lo rau yuav luag txhua qhov chaw. Tab sis qee zaum dej-raws li primer tuaj yeem raug khawb tawm.
Peb feem ntau siv cov yas primers uas paub lub npe hu ua yas adhesion txhawb nqa. Lawv yog cov khoom lag luam muaj txiaj ntsig zoo hauv kev ua kom zoo dua qhov adhesion ntawm cov xim tom ntej, nrog rau cov xim pleev xim lossis cov xim pleev xim rau saum npoo.
Feem ntau, adhesion primers pab txuag qhov chaw ntawm cov khoom uas muaj kev sib raug zoo nyob rau theem tom ntej. Yog li ntawd, nws muab kev yooj yim dua hauv kev tsim khoom. Peb tuaj yeem xav txog cov nplaum nplaum ua cov nplaum nplaum nplaum ua ke nrog cov khoom sib txuas xws li silane. Lub luag haujlwm tseem ceeb ntawm qhov sib tov no yog kom ntub cov khoom tshiab uas tau npaj tau yooj yim.
Qhov txawv ntawm Adhesion Promoter thiab Primer yog dab tsi?
Adhesion txhawb nqa thiab adhesion primers yog cov khoom tseem ceeb hauv cov xim thiab txheej. Qhov sib txawv tseem ceeb ntawm adhesion promoter thiab primer yog tias adhesion promoters yog additives rau cov xim los txhawb cov adhesion ntawm cov xim zaj duab xis rau substrate, whereas adhesion primers yog dilute cov kev daws teeb meem kom txuag tau qhov chaw ntawm cov khoom uas muaj bonded nyob rau hauv ib tug tom qab theem.
Cov lus hauv qab no qhia txog qhov sib txawv ntawm tus neeg txhawb nqa adhesion thiab primer.
Summary – Adhesion Promoter vs Primer
Tus adhesion txhawb nqa yog ib qho ntxiv rau cov xim uas muaj txiaj ntsig hauv kev txhawb nqa cov adhesion ntawm zaj duab xis rau substrate. Ib qho adhesion primer, ntawm qhov tod tes, yog ib qho kev daws teeb meem ntawm cov nplaum hauv cov kuab tshuaj organic. Qhov sib txawv tseem ceeb ntawm adhesion txhawb nqa thiab primer yog lawv txoj haujlwm; adhesion promoters ua raws li cov additives rau cov xim los txhawb lub adhesion ntawm cov xim zaj duab xis rau lub substrate, tab sis adhesion primers khaws cia rau saum npoo ntawm cov ntaub ntawv uas muaj bonded nyob rau hauv ib tug tom qab theem.
