Lub hom phiaj tseem ceeb ntawm extruded board thiab nws daim ntawv thov nyob rau hauv sab nraud thermal rwb thaiv tsev ntawm sab nrauv phab ntsa extruded board muaj cov qauv ntawm nruam thiab uniform nto txheej thiab kaw cell honeycomb qauv. Cov qauv no tsim cov tuab tuab honeycomb phab ntsa, uas txuas nrog zoo thiab tsis muaj qhov sib txawv ntawm cov phab ntsa. Cov qauv zoo li no ua rau lub rooj tsavxwm extruded muaj qhov kub thiab txias thiab thermal rwb thaiv tsev kev ua tau zoo, superior noo noo tsis kam thiab siab compressive zog. Yog li ntawd, qhov tseeb, lub hom phiaj tseem ceeb ntawm extruded board txawv teb chaws yog
1 lub ru tsev thermal rwb thaiv tsev thiab kev tiv thaiv ntawm waterproof txheej (inverted ru tsev)
2 qhov chaw cia txias txias (tsawg kub cia txias, tsheb tub yees)
3. Pave cushion los tswj av te heave nyob rau hauv lub pavement thiab subgrade ntawm txoj kev loj, railway thiab tshav dav hlau khiav nyob rau hauv alpine cheeb tsam:
4. Filling thiab tso cov plag tsev uas raug tshem tawm xws li hauv pem teb sib xyaw. Tib lub sijhawm, nws kuj yog siv rau cov dej noo- pov thawj, thermal rwb thaiv tsev thiab suab rwb thaiv tsev. Nws yog siv los tso thermal rwb thaiv tsev nyob rau hauv pem teb radiant cua sov.
In foreign countries, extruded boards are generally not used in the external insulation of exterior walls, and there are no relevant standards and specifications. However, after the arrival of extruded board in China, its main uses have undergone significant changes. In addition to the above uses, other uses have been developed according to China's national conditions:
1. Reinforced qhob ru tsev thermal rwb thaiv tsev thiab profiled steel ntawv ru tsev thermal rwb thaiv tsev
2 mus tas li los yog ib ntus formwork rau pob zeb pouring
3. Sab nrauv rwb thaiv tsev ntawm cam khwb cia-hauv-situ qhob meshless extruded phaj:
4. Sab nrauv rwb thaiv tsev ntawm cam khwb cia-hauv-situ qhob inclined embedded steel hlau daim phiaj extruded phaj:
5. Sab nraud thermal rwb thaiv tsev system ntawm mechanically tsau extruded steel hlau daim phiaj phaj
6 extruded board nyias plastering sab nrauv rwb thaiv tsev
7. Sab nrauv kho kom zoo nkauj thiab thermal rwb thaiv tsev system ntawm extruded board, thiab lwm yam.
Txawm hais tias cov txheej txheem rwb thaiv tsev sab nraud no tau siv hauv Suav teb tau ntau xyoo, lawv muaj teeb meem ntau dua lossis tsawg dua. Txog tam sim no, tsis muaj cov qauv hauv tebchaws, cov qauv kev lag luam, cov qauv atlas thiab cov txheej txheem tsim kho tau raug tshaj tawm. Lawv daim ntawv thov kuj tseem muaj teeb meem. Txawm li cas los xij, vim tias lub rooj tsavxwm extruded muaj kev ua haujlwm siab compressive thiab cuam tshuam toughness. Tsis tas li ntawd, kev txhawb nqa kev siv tshwj xeeb hloov tau yooj yim tawg resistant mortar thiab alkali resistant mesh daim ntaub tuaj yeem ua rau cov rwb thaiv tsev sab nraud muaj kev cuam tshuam zoo dua. Yog li ntawd, nws yog feem ntau lees paub tias nws yog siv rau kev rwb thaiv tsev sab nraud ntawm thawj phab ntsa sab nrauv ntawm lub tsev, thiab nws cov qauv kev nyab xeeb yog ntsia hlau, ntxiv los ntawm cov kua nplaum.
