Sandwich phaj yog ib lub phaj uas txhawb nqa nws tus kheej ua ke ntawm bimetallic nto thiab insulating cov khoom tseem ceeb sib txuas ntawm ob qhov hlau. Nws suav nrog kev tiv thaiv hluav taws, thermal rwb thaiv tsev, dej tsis zoo, huab cua tsis kam, cua tsis kam, compression tsis kam, suab nqus thiab suab rwb thaiv tsev. Nyob rau hauv xyoo tas los no, nws tau siv dav hauv ntau lub tsev lag luam. Sandwich vaj huam sib luag yog tsim los ntawm cov khoom siv nto thiab cov khoom tseem ceeb. Cia peb nkag siab txog cov khoom siv ntawm lub vaj huam sib luag sandwich:
1. Hlau phaj
Cov xim coated steel phaj yog ua los ntawm txias-kuav los tiag steel phaj, electro galvanized steel phaj, kub-dip galvanized steel phaj los yog txhuas zinc plated steel phaj raws li substrate. Tom qab degreasing, phosphating thiab chromate kho, cov organic txheej yog txuas ntxiv rau cov menyuam coated thiab ci. Tag nrho cov txheej txheem mus dhau los ntawm kev tswj hwm ntau lawm thiab kev tswj kom zoo. Cov txheej txheem rau cov xim coated steel phaj muaj xws li PVDF polyvinylidene fluoride, HDP huab cua tiv taus polyester, PE polyester txheej, thiab lwm yam.
2. Aluminium phaj
Kev tiv thaiv corrosion zoo tuaj yeem txhim kho tag nrho cov kav ntev ntawm lub tsev, uas yog tib lub voj voog raws li lub tsev lub neej. Nws muaj qhov yooj yooj yim thiab kev ua haujlwm zoo. Cov xim pleev xim yog tsis tawg. Nws tuaj yeem ua tiav rau hauv ntau yam kev sib sau ua ke xws li dav hlau thiab arc. Nws yog lub teeb hauv qhov hnyav tab sis siab zog thiab muaj txiaj ntsig zoo dua qub.
3. Pob zeb wool / iav ntaub plaub
Pob zeb wool sandwich board yog ib hom sandwich board ua los ntawm basalt. Nws muaj kev tiv thaiv hluav taws zoo heev, kev ua haujlwm zoo suab rwb thaiv tsev thiab kev rov ua dua tshiab. Cov iav ntaub plaub uas tsis yog combustible, lub teeb yuag, me me thermal conductivity, zoo suab haum, zoo waterproof kev ua tau zoo, corrosion kuj, zoo tshuaj stability, zoo ua hauj lwm, thiab zoo economic applicability.
4. Polyurethane PIR / pur
Rigid polyurethane muaj cov yam ntxwv ntawm noo noo-pov thawj, waterproof, fireproof, nplaim-retardant, kub tsis kam, khov-thaw kuj thiab suab haum. Nrog ultra-siab kub stability thiab hluav taws kub ntsuas, thiab tsis muaj Freon emission, txuag hluav taws xob thiab kev tiv thaiv ib puag ncig, nws tuaj yeem siv dav hauv kev lag luam hauv tsev cia txias.
Cov ntaub ntawv sandwich sib txawv tuaj yeem xaiv tau raws li qhov sib txawv ntawm qhov project. Tsis tas li ntawd, cov sandwich panels muaj qhov zoo ntawm kev teeb tsa sai thiab muab tso rau hauv kev siv, detachability thiab turnover thiab rov qab siv cov ntaub ntawv, thiab yog indispensable tshiab lub teeb lub tsev cov ntaub ntawv.
