Background technology
Many The building light-transmission type materials are gone along with sb. to guard him this going along with sb. to guard him in whole or in part---and be commonly referred to " curtain wall ", glass curtain wall is present widely used a kind of light-transmission type building enclosure.It singly is not to guarantee effectively to go along with sb. to guard him function that building enclosure adopts the main purpose of light-transmission type material, also will satisfy daylighting and decoration demand simultaneously.Therefore; This light-passing board not only will have bigger veneer area, good mechanical performance, relatively low thermel expansion coefficient, higher thermal resistance and sound insulation property and long service life, also will have good light transmittance, more color, favorable surface quality and texture simultaneously.
Can be used as the light transmissive material that decorating building goes along with sb. to guard him mainly contains: inorganic, organic and composite light-passing board three major types.The basic material of inorganic light-passing board is mainly plate glass; The kind of organic light-passing board is more, mainly contains PMMA (acrylic, polymethyl methacrylate), PC (Merlon), PS (polystyrene), PP (polypropylene) and transparent PVC thermoplastic plastics such as (polyvinyl chloride) and adopts the sheet material that prolongs pressure or expressing technique manufacturing; The composite light-passing board comprises: light-transmission type FRP (fiberglass) plate, printing opacity stone (artificial stone light-passing board) and compound printing opacity battenboard etc.
In above-mentioned three types of light transmissive materials,, any bill of materials goes along with sb. to guard him all on performance the some shortcomings that exist more or less no matter being solely used in curtain wall.For example: plate glass exists that fragility is high, the coefficient of heat conduction is high and deficiency such as the veneer area is less, makes performance obtain some improvement though can lean on PROCESS FOR TREATMENT such as tempering, plated film, interlayer and improve veneer thickness, and performance is still barely satisfactory.Acrylic in organic light-passing board (lucite) light transmittance is high, and the light transmittance of Merlon and comprehensive mechanical performance are all fine, but has limited in architectural application because of reasons such as these material prices height, veneer area are less.Also have at present adding Al honeycomb (or plastic honeycomb) in the middle of two PMMA plates (or transparent PS plate), process the printing opacity sandwich plate that can under light, manifest honeycomb, be used for screen, artistic veneer and cabinet door etc. and located decoration function.These printing opacity sandwich plates are used for outdoor owing to reasons such as mechanical strength and resistance to ag(e)ing are less.Fiberglass daylighting in the composite watt (plate) is used as the printing opacity roofing widely, but its thinner thickness can't satisfy the requirement of building enclosure to plate face rigidity and heat transfer coefficient.
Above-mentioned three major types printing opacity sheet material is because the restriction of material property and manufacturing process; When being used for building enclosure; Some inadequate natural endowments are all arranged; Particularly the problem of organic material on weatherability is more more, and this has just limited the use of organic light transmissive material as the building enclosure material, to such an extent as to formed the helpless situation that present glass curtain wall " is outshined othersOne branch of the tree is particularly thriving ".Simultaneously, no matter be glass or transparent plastic, the sheet material of large format can not be provided because of the restriction of material property, production technology, capacity of equipment and manufacturing cost all.Under common processes, the veneer maximum area of cladding glass is: single (folder) layer glass≤4.5m
2/ piece, double glazing≤3.2m
2/ piece.At present, some significant famous buildings and large-scale landscape structures have proposed very high requirement to the plate face and the performance of curtain wall cladding.For example, the curtain wall in building, Chinese Central Television new address, the double glazing that has adopted special technique to make, wherein maximum veneer area has 7m
2, thickness 70mm, weight reaches 650kg, can be rated as double glazing.But if the bigger veneer area of demand, prior art just can't satisfy so.
