1. Taw qhia
Butyl Rubber Adhesive Daim kab xevyog ib qho kev ua haujlwm siab -kev ua tau zoo, tus kheej-fusing sealing daim kab xev engineered feem ntau los ntawm butyl roj hmab, ib tug hluavtaws elastomer paub txog nws tshwj xeeb impermeability rau gases thiab ya raws. Tsis zoo li cov pa siab zoo- cov ntaub nplaum nplaum, butyl daim kab xev tsim ib qho chaw ruaj khov, tsis yog- hardening foob los ntawm autogenous bonding (tus kheej-adhesion), ua rau nws yog ib qho tseem ceeb ntawm ntau qhov kev thov kev lag luam thiab kev tsim kho. Cov ntaub ntawv no muab cov ntaub ntawv qhia dav dav ntawm nws cov khoom sib xyaw, cov khoom siv, kev siv, thiab cov txheej txheem tuav.
2. Chemical Composition thiab Structure
Ntawm nws cov tub ntxhais, butyl roj hmab nplaum daim kab xev muaj cov roj hmab butyl -raws li compound. Butyl roj hmab (isobutylene-isoprene roj hmab, IIR) yog ib qho copolymer uas muaj cov pob txha saturated nrog tsawg kawg nkaus unsaturation, muab nws superior stability.
Base Polymer:Polyisobutylene (PIB) los yog Butyl Roj Hmab (IIR) tsim cov pob txha, muab cov khoom siv hauv lub cev, hloov tau yooj yim, thiab dej tsis kam.
Fillers thiab Reinforcements:Cov ntaub ntawv zoo li carbon dub lossis calcium carbonate tau ntxiv los txhim kho lub zog tensile, tsim kua muag, thiab UV stability.
Plasticizers thiab Roj:Cov khoom no kho cov kab xev softness, tack theem, thiab elongation zog.
Antioxidants thiab Stabilizers:Tseem ceeb rau kev ua haujlwm ntev -, cov tshuaj ntxiv no tiv thaiv cov polymer los ntawm kev degradation vim ozone, UV hluav taws xob, thiab cua sov.
Cov kab xev feem ntau tsis yog-woven thiab txhawb nqa, qee zaum nrog cov ntaub sib sib zog nqus los yog zaj duab xis scrim los txhim kho kev tuav thiab lub zog txhua yam yam tsis muaj kev cuam tshuam kev sib haum xeeb.
3. Cov yam ntxwv tseem ceeb thiab kev ua tau zoo zoo
Butyl roj hmab daim kab xev yog xaiv rau nws cov cim ua ke ntawm cov khoom:
Dej zoo heev thiab vapor impermeability:Nws qhov tseem ceeb tshaj plaws yog tsim kom muaj qhov ze ntawm -txoj kev tiv thaiv tsis muaj dej noo thiab dej vapor, ua rau nws zoo tagnrho rau kev siv dej tsis zoo.
Kev Tiv Thaiv Tus Kheej thiab Tus Kheej -Fusing:Cov kab xev nplaum fuse ua ke thaum sib cuag, tsim ib qho seamless, monolithic foob tsis muaj cov nplaum sib txawv. Qhov no tiv thaiv ntug lifting thiab channeling.
Superior Weatherability thiab UV Resistance:Nws nthuav tawm cov kev tiv thaiv zoo rau kev laus, ozone, thiab ultraviolet lub teeb, ua kom lub sijhawm ntev - ua haujlwm nyob rau hauv ib puag ncig sab nraum zoov.
High Conformability thiab Elongation:Cov kab xev tuaj yeem ncab thiab ua raws li qhov chaw tsis sib xws, cov duab nyuaj, thiab cov pob qij txha nthuav dav / sib cog lus yam tsis ua haujlwm.
Cov tshuaj tiv thaiv zoo heev:Nws ua tau zoo tiv thaiv ntau yam tshuaj, suav nrog acids, alkalis, thiab saline daws.
Tsis yog -Ntxhais thiab Tsis yog- Kho:Tsis zoo li qee cov sealants, butyl daim kab xev tseem hloov tau mus tas li thiab tsis tawv nqaij dhau los yog ua rau muaj hnub nyoog.
Muaj zog Adhesion rau ntau yam substrates:Nws sib raug zoo rau ntau yam ntaub ntawv, suav nrog hlau (aluminium, steel), yas (PVC, ABS), iav, pob zeb, thiab ntoo.
