koj puas paub? Thaum lub caij ntuj no, cov txheej txheem sealant tseem yuav zoo li menyuam yaus, ua rau muaj kev npau taws me me, yog li nws yuav ua rau muaj teeb meem dab tsi?
1.Structural sealant thickening
Cov txheej txheem sealants yuav maj mam thicken thiab ua kua dej tsawg dua li qhov kub thiab txias. Rau ob lub ntsiab lus sealant, lub thickening ntawm cov txheej txheem sealant yuav ua rau kom lub siab ntawm lub tshuab kua nplaum thiab txo cov extrusion ntawm cov qauv sealant. Rau ib qho khoom siv sealants, cov txheej txheem sealant thickens, thiab lub siab ntawm cov kua nplaum phom kom extrude cov txheej txheem sealant nce, thiab kev siv phau ntawv yuav xav tias siv sijhawm thiab ua haujlwm hnyav.
Kev daws: Yog tias tsis muaj kev cuam tshuam rau kev tsim kho kev ua haujlwm, qhov kub tsis tshua muaj tuab yog qhov tshwm sim ib txwm muaj, thiab tsis tas yuav tsum ntsuas kev txhim kho. Yog tias nws cuam tshuam rau kev tsim kho kom zoo, koj tuaj yeem xav txog kev siv qhov kub thiab txias ntawm cov txheej txheem sealant los yog siv qee qhov kev ntsuas cua sov, xws li khaws cov txheej txheem sealant hauv chav cua sov lossis chav cua txias ua ntej. Txhim kho cua sov hauv gluing Rhiav kom nce qhov kub ntawm qhov chaw gluing. Tsis tas li ntawd, koj tuaj yeem xaiv cov cuab yeej ua kua nplaum uas tsim nyog, xws li phau ntawv nplaum phom nrog lub siab thrust, pneumatic kua nplaum phom, phom hluav taws xob, thiab lwm yam.
2.Weathering sealant bulges - tsis sib xws
Nyob rau lub caij ntuj no, qhov kub sib txawv nruab hnub thiab hmo ntuj feem ntau loj. Thaum ua ntawv thov rau lub txhuas vaj huam sib luag kab hlau rhuav phab ntsa, cov huab cua-resistant sealant yog nws bulging. Qhov laj thawj tseem ceeb yog qhov kev kho ceev ntawm huab cua-resistant sealant ua qeeb qeeb hauv qhov chaw tsis muaj qhov kub thiab txias, thiab lub sij hawm xav tau rau qhov chaw kho kom zoo rau qhov tob txaus yuav ntev dua. Nyob rau saum npoo ntawm huab cua-resistant sealant Thaum qhov tob ntawm cov kua nplaum tsis tau kho txaus, yog tias qhov dav ntawm cov kua nplaum sib txawv heev (qhov no feem ntau yog tshwm sim los ntawm thermal expansion thiab contraction ntawm lub vaj huam sib luag), qhov saum npoo ntawm cov kua nplaum. kua nplaum yuav raug cuam tshuam thiab qhov tsis sib xws yuav tshwm sim. Tom qab cov nplaum nplaum nrog qhov tsis sib xws yog thaum kawg kho, nws sab hauv yog khoom, tsis hollow, uas yuav tsis cuam tshuam rau lub sij hawm ntev sealing kev ua tau zoo ntawm huab cua-resistant sealant, tab sis tsuas yog cuam tshuam lub flatness ntawm cov tsos ntawm cov nplaum nplaum.
Tom qab lub caij ntuj no, thaj chaw loj txias, qhov kub thiab txias yog qhov tsawg, thiab qhov kub ntawm qhov sib txawv thaum sawv ntxov thiab yav tsaus ntuj yog qhov loj. Vim qhov loj coefficient ntawm linear expansion ntawm cov khoom, aluminium vaj huam sib luag kab hlau rhuav phab ntsa deforms ho nrog kub. Nyob rau hauv cov xwm txheej saum toj no ntawm cov txheej txheem sealant siv, muaj qee qhov ua tau tias cov kua nplaum sib txuas ntawm aluminium vaj huam sib luag kab hlau rhuav phab ntsa yuav bulge.
Kev daws:
1.Xaiv cov kua nplaum nrog kev kho ceev ceev, uas tuaj yeem txo qhov teeb meem ntawm huab cua-resistant sealant.
2.Yog hais tias tus txheeb ze deformation ntawm cov kua nplaum sib koom ua ke loj heev vim tsis muaj av noo los yog qhov kub thiab txias sib txawv, cov kua nplaum sib koom ua ke, thiab lwm yam, nws raug nquahu kom xaiv ib lossis ntau txoj hauv qab no rau kev tsim kho.
a) Siv cov kev ntsuas shading tsim nyog, xws li tiv thaiv lub scaffolding nrog cov plua plav pov thawj nets, kom cov panels tsis ncaj qha mus rau tshav ntuj, txo qhov kub ntawm lub panels, thiab txo cov deformation ntawm cov pob qij txha los ntawm qhov kub thiab txias.
b) Sim npaj gluing thaum tav su, thiab tsis txhob gluing thaum sawv ntxov thiab yav tsaus ntuj.
c) Siv cov txheej txheem ntawm daim ntawv thov cov kua nplaum thib ob (uas yog, yog tias muaj cov kua nplaum sib txuas hauv thawj daim ntawv thov kua nplaum, nws tuaj yeem kho tau 2 mus rau 3 hnub, thiab tom qab nws muaj elasticity, ib txheej ntawm cov kua nplaum ntxiv rau. qhov chaw).
