Adhesive Fiberglass Mesh Daim kab xev xim: Puas muaj qhov txawv ntawm Liab, Daj, thiab Dub?

 

Thaum xaiv cov nplaum fiberglass mesh daim kab xev, ntau tus neeg siv khoom pom tias cov khoom muaj ntau yam xim -liab, daj, dub, thiab dawb- thiab ib txwm nug: cov xim puas cuam tshuam rau kev ua haujlwm? Lo lus teb tsis yog. Cov xim nws tus kheej tsis txiav txim siab daim kab xev cov khoom siv los yog daim ntawv cog lus lub zog. Ntawm lawv, cov xim dawb yog cov xim zoo tshaj plaws thiab cov qauv, thaum liab, daj, thiab dub yog xim xim lossis xim xaiv. Rau cov kab xev los ntawm tib hom, nrog rau tib qhov tshwj xeeb thiab cov xim sib txawv, fiberglass mesh substrate thiab cov nplaum nplaum yog feem ntau zoo tib yam. Cov xim tsuas yog los ntawm cov xim lossis cov xim ntxiv rau cov nplaum txheej lossis cov txheej mesh. Txawm li cas los xij, hauv kev xyaum, cov xim sib txawv sib haum rau qee qhov kev nyiam ntawm daim ntawv thov thiab qhov chaw tus cwj pwm. Hauv qab no, peb piav qhia lub hauv paus ntawm cov xim, nws cov txiaj ntsig ntawm kev ua haujlwm, thiab cov lus pom zoo xaiv.

 

Ib, xim tuaj qhov twg?

Cov xim ntawm fiberglass self-adhesive daim kab xev yog los ntawm ob qhov chaw. Dawb feem ntau yog los ntawm cov xim ntuj ntawm cov fiberglass yarn nws tus kheej, ua ke nrog cov xim dawb xws li titanium dioxide ntxiv rau hauv cov nplaum txheej - ua rau nws yog xim xim xim. Liab, daj, dub, thiab lwm yam xim yog ua tiav los ntawm kev ntxiv pigments rau txheej los yog impregnation kho ntawm fiberglass mesh nto, nrog rau cov nplaum formulation. Cov pigments no yog inert colouring agents uas tsis koom nyob rau hauv cov nplaum cov tshuaj cross-linking tshua. Yog li ntawd, lawv tsis hloov daim kab xev lub zog tensile, tsim kua muag tsis kam, alkali tsis kam, los yog nplaum nplaum lub zog. Nyob rau tib txoj kab ntau lawm, hloov cov xim tsis kho cov txheej txheem tseem ceeb.

2, Kev siv ntau yam xwm txheej cuam tshuam nrog cov xim sib txawv

Txawm hais tias tsis muaj qhov sib txawv ntawm kev ua tau zoo, kev lag luam xyaum tau tsim qee yam kev cai xim nyiam:

• Dawb (xim xim): Raws li lub hauv paus xim, daim kab xev dawb rau nws tus kheej yog haum rau feem ntau ntawm cov kev siv lub hom phiaj, xws li kev kho phab ntsa ntub dej, kho phab ntsa tawg, thiab kev tiv thaiv yeeb nkab. Thaum tsis muaj xim tshwj xeeb yuav tsum tau, xim dawb yog qhov kev xaiv ua ntej thiab cov khoom lag luam yooj yim tshaj plaws.
• Liab: Liab daim kab xev nplaum rau tus kheej feem ntau yog siv rau kev ceeb toom kev nyab xeeb, cov cim tiv thaiv hluav taws, lossis kev piav qhia thaj chaw muaj kev phom sij. Hauv cov chaw tsim khoom, tsev khaws khoom, lossis chaw tsim kho, daim kab xev liab feem ntau yog siv los cim cov cheeb tsam txwv, cov kav dej siab siab, lossis thaj chaw nyob ib puag ncig cov khoom siv thaum muaj xwm txheej ceev, muab kev ceeb toom zoo. Liab tsis yog xim hom phiaj tab sis ua haujlwm tshwj xeeb rau kev txheeb xyuas lub hom phiaj.
• Yellow: Daj daim kab xev rau nws tus kheej muaj kev pom ntau dua ntawm qhov chaw tsim kho, ua kom yooj yim rau cov neeg teeb tsa los xyuas seb daim kab xev puas tau muab tso rau kom raug thiab seb cov npoo puas raug nias. Nyob rau hauv tej yaam num uas yuav tsum tau soj ntsuam nruj zoo, daj yog pom tau yooj yim dua los ntawm cov neeg ua hauj lwm tswj kom zoo, pab txheeb xyuas cov seem uas ploj lawm los yog lifted ntug- ua rau nws yog ib tug muaj txiaj ntsim kev ruaj ntseg cuab yeej.
• Dub: Dub daim kab xev nws tus kheej feem ntau yog siv rau hauv kev ua haujlwm zais lossis ntawm cov xim tsaus nti substrates uas xav tau kev sib xyaw ua kom zoo nkauj. Piv txwv li, nyob rau hauv asphalt waterproofing membrane lap joints los yog dub pob zeb structural kho, dub daim kab xev yog tsawg conspicuous thiab ua tau raws li tej yam kev xav. Tsis tas li ntawd, cov nplaum nplaum dub muab UV tiv thaiv me ntsis zoo dua li cov khaubncaws sab nraud povtseg, muab kev tiv thaiv zoo dua thaum lub sijhawm luv luv sab nraum zoov (txawm hais tias huab cua ntev ntev tseem nyob ntawm cov khoom tsim UV-resistant).

Cov xim uas tau hais tseg saum toj no yog qhov teeb meem ntawm kev lag luam kev sib cog lus es tsis yog cov qauv kev cai. Tsis muaj qhov tshwj xeeb engineering tau txiav txim siab siv cov xim tshwj xeeb hauv ib qho ntsiab lus tshwj xeeb.

3, Cov lus qhia xaiv: xim tsis yog qhov tseem ceeb; specifications yog dab tsi tseem ceeb

Rau kev yuav khoom thiab siv cov nplaum fiberglass mesh daim kab xev, peb cov lus pom zoo yog qhov tseeb:

• Ua ntej xaiv cov xim, paub meej tias cov khoom tseem ceeb tsis zoo li cas -xws li gram hnyav (piv txwv li, 110g), mesh loj, tensile zog, alkali tsis kam, thiab hom nplaum (xws li, epoxy-based lossis tsis){6}}ua tau raws li qhov yuav tsum tau ua.
• Xaiv cov xim raws li xav tau: Yog tias qhov project tsis muaj qhov tshwj xeeb xim yuav tsum tau, ua qhov tseem ceeb ntawm cov khoom lag luam tus qauv dawb- nws yog qhov zoo tshaj plaws, yooj yim tshaj plaws, thiab muaj qhov zoo tshaj plaws tus nqi-kev ua tau zoo. Yog xav tau kev ceeb toom kev nyab xeeb lossis kev txheeb xyuas thaj chaw, yuav xaiv liab. Rau cov haujlwm uas muaj kev soj ntsuam nruj ntawm qhov chaw zoo, xim daj yuav yog qhov kev xaiv zoo dua rau kev kuaj pom kev yooj yim. Rau qhov chaw zais lossis cov xim tsaus nti, cov xim dub yuav nyiam dua.
• Tsis txhob txiav txim siab zoo los ntawm cov xim: Tsis txhob xav tias ib xim yog "zoo dua" lossis "phem" dua li lwm tus. Los ntawm tib lub chaw tsim khoom thiab cov khoom lag luam tib yam, cov khoom sib txawv ntawm cov xim muaj qhov ua tau zoo ib yam - xim tsuas yog ib qho kev tshwm sim, tsis yog qib ntsuas.

Xim variation ntawmadhesive fiberglass mesh daim kab xevtsis cuam tshuam rau nws cov neeg kho tshuab kev ua tau zoo lossis kev ntseeg siab ntawm kev sib koom ua ke. Dawb yog cov qauv xim, haum rau feem ntau ntawm kev siv niaj hnub; liab, daj, thiab dub yog kev xaiv xaiv raws li cov kev xav tau tshwj xeeb. Lub hauv paus ntawm cov khoom xaiv ib txwm nyob rau hauv specifications thiab daim ntawv thov haum, tsis yog xim. Xaiv cov xim raws li koj qhov project xav tau, thiab mob siab rau kom paub tseeb tias cov khoom siv cov ntaub ntawv ua tau raws li koj qhov kev tsim kho.
