Butyl Daim kab xev yog dab tsi?
Butyl daim kab xev yog ib tug siab -kev ua tau zoo, yas mus tas li, thiab tsis yog - kho sealing daim kab xev uas muaj feem ntau ntawm polyisobutylene (butyl roj hmab). Tsis zoo li cov nplaum nplaum ib txwm siv uas tso siab rau qhov adhesion, butyl daim kab xev ua haujlwm dhau loscohesive zog. Nws fuses rau nws tus kheej thiab tsim ib tug tenacious, waterproof daim ntawv cog lus nrog ntau yam substrates.
Vim tias nws tseem hloov tau mus tas li thiab tsis tawv los yog ua rau lub sijhawm ntev, butyl daim kab xev yog cov qauv kev lag luam rau cov ntawv thov uas yuav tsum tau ua kom ntev ntev - weatherproofing, vibration damping, thiab kev tiv thaiv los.
Cov Khoom Tseem Ceeb & Cov Lus Qhia Tshwj Xeeb
Thaum xaiv ib qho kev sib khi, kev nkag siab txog lub cev lub cev yog qhov tseem ceeb. Butyl daim kab xev muaj qhov sib xyaw ua ke ntawm cov yam ntxwv uas hluavtaws roj hmab thiab acrylics tsis tuaj yeem sib xws:
Waterproof Foob:Butyl roj hmab muaj qhov tshwj xeeb uas tsis tshua muaj ya raws vapor kis tus nqi (MVTR), tsim kom muaj kev ua tiav hydraulic tiv thaiv los nag, daus, thiab condensation.
Tsis yog -Kho & Permanent Flexibility:Cov ntaub ntawv yeej ib txwm hardens. Nws tuav elasticity kom haum rau thermal expansion, contraction, thiab structural txav tsis muaj cracking.
High Cohesion:Nws adheres rau nws tus kheej. Thaum compressed, cov molecules sib koom ua ke los tsim ib qho kev sib koom ua ke uas muaj zog dua li daim ntawv cog lus rau substrate.
Kub Resistance:High -qib butyl daim kab xev tseem siv tau nyob rau hauv qhov kub thiab txias xws li-40 ° F (-40 ° C) txog 250 ° F (121 ° C) .
UV & Ozone Resistance:Nws tiv taus degradation los ntawm ultraviolet hluav taws xob thiab ozone raug, ua kom lub neej ntev nyob rau hauv ib puag ncig sab nraum zoov.
Dielectric zog:Butyl roj hmab yog cov khoom siv hluav taws xob zoo heev, ua rau nws muaj kev nyab xeeb rau kev siv hauv cov khoom siv hluav taws xob thiab cov khoom siv hluav taws xob hauv tsheb.
Cov ntawv thov tseem ceeb
Butyl daim kab xev yog ntau yam kev daws teeb meem siv thoob plaws ntau lub lag luam. Hauv qab no yog nws cov ntawv thov kev tshaj lij tshaj plaws:
1. RV thiab Automotive Kev Lag Luam
Hauv kev ua si tsheb thiab kev tsim tsheb, butyl daim kab xev yog cov khoom siv zoo tshaj plaws rau kev sib khi cov pob qij txha uas cov khoom sib dhos ua tau raws li cov qauv yooj yim.
Roof Seams:Sealing qhov sib txuas ntawm EPDM lossis TPO roj hmab ru tsev thiab lub cev tsheb.
Qhov rai & Teeb Installation:Lub txaj sab qhov rais, tshem cov teeb pom kev zoo, thiab lub teeb tom qab kom tsis txhob muaj dej nkag.
Accessory Mounting:Sealing lub ru tsev vents, cua txias units, thiab nra racks.
2. Kev tsim kho & glazing
Architects thiab glaziers cia siab rau butyl daim kab xev rau kab hlau rhuav phab ntsa thiab cov qauv glazing.
iav rau hlau:Sealing iav panels rau hauv aluminium lossis steel ncej.
Flashings:Siv los ua cov ntaub pua chaw pw rau hlau flashings, ncaws- tawm flashing, thiab los ntawm- phab ntsa flashings.
Prefabricated Panels:Tsim huab cua- nruj seals ntawm precast qhob lossis insulated hlau panels.
3. Kev siv dej hiav txwv
Marine ib puag ncig xav tau huab cua tiv thaiv corrosion thiab yooj.
Kho vajtse Deck:Sealing deck fittings, cleats, thiab chainplates kom tiv thaiv cov dej ntsev nkag.
Hull Penetrations:Sealing los ntawm -cov fittings thiab transducer mounts.
4. HVAC & Hluav taws xob
Tube Sealing:Sealing seams nyob rau hauv daim ntawv hlau ductwork los tiv thaiv huab cua to.
Hluav taws xob Enclosures:Muab lub foob gasket rau cov thawv sib txuas thiab cov teeb pom kev sab nraum zoov kom tswj tau qhov kev ntsuas NEMA.
Installation Cov kev coj ua zoo tshaj plaws
Yuav kom ua tiav lub foob mus tas li, kev npaj kom zoo thiab cov txheej txheem yog qhov tseem ceeb.
1. Kev npaj nto
Lub substrate yuav tsum huv si, qhuav, thiab tsis muaj kab mob. Tshem tawm cov av, roj, roj, thiab qub sealant residue. Siv isopropyl cawv los yog ib lub tshuab ntxhua khaub ncaws. Rau qhov zoo tshaj plaws adhesion, qhov chaw yuav tsum yogkuab tshuaj-dawbthiab nyob rau hauv chav tsev kub (siab tshaj 50 ° F / 10 ° C).
2. Daim ntawv thov
Tsis txhob ncab daim kab xev.Thov nws nyob rau hauv nws lub xeev so. Stretching txo tus ntoo khaub lig-sectional cheeb tsam thiab tuaj yeem ua rau lub foob tsis ua haujlwm.
Rau sealing flanges los yog qhov rais, thov daim kab xev rau lubqhuavnto, ces position lub mating tivthaiv.
Siv alap sib(overlapping xaus) es tsis yog lub pob tw sib koom thaum kaw qhov ib puag ncig.
3. Compression
Butyl daim kab xev seals nyob rau hauv compression. Thaum zawm bolts los yog teeb iav, xyuas kom meej tias txawm tias siv zog. Lub butyl ntau dhau uas nyem tawm qhia tias muaj lub foob tag nrho; Qhov ntau dhau tuaj yeem txiav nrog cov yas scraper tom qab kho.
4. Lub sij hawm kho
Thaum butyl daim kab xev ntsaws ruaj ruaj tam sim ntawd, tag nrho adhesion tsim dhau 24 mus rau 72 teev nyob ntawm qhov kub thiab txias.
