Light steel keel partition wall installation should pay attention to the following essentials: the top and bottom should be used along the top keel and along the ground keel. There should be a vertical keel in the vertical direction and a keel in the door frame. The transverse direction should have a transverse keel. Its accessories include support cards, card holders, corner brackets, connectors and fasteners. These materials are indispensable. The keel along the top and the keel along the ground should be fixed according to the position of the elastic line. The fixing method can be used for nailing, expansion bolts, etc., and the nail distance is not more than 600mm. Vertical keels against the wall and column can be fixed with nails, expansion bolts or wood screws and walls and columns. The nail distance is not more than 900mm. The middle vertical keel shall be set according to the width of the cover panel, not more than 1/2 plate width plus gap width (usually 5mm), and the spacing shall not be greater than 600mm. When the two partition walls are connected longitudinally and laterally, the vertical keel of the intersection is not to be omitted. The cross keel can be fixed by the support card, the card holder and the connecting piece. If necessary, it can be fixed by the blind rivet, but it should not be welded by electric welding. The spacing of the transverse keels should not be greater than 120Omm. A keel must be placed at the seam of the cover panel. The keel shall not be cut or reduced in cross section. The light steel keel partition wall frame can meet the above requirements, which can eliminate the quality problems caused by the structural installation. During the construction process, attention should be paid to the inspection, mainly using manual test and observation inspection methods.
UV Laser Marking Machine is suitable for almost all material's marking, especially outstanding performance for plastic.Advantages of UV laser marking machineFocused UV light spot size is small , heat-affected area during processing is mimimum,So it is used in ultra-fine and special material`s marking. Since UV laser did not produce any thermal effects and burning issues, the result of the marking is precise , smooth and steep.A lot of material will absorb UV light at 355nm except Copper, so UV laser are suitable for processing more types of material Applications of UV laser marking machineHigh end ultra-fining market: cosmetics, pharmaceuticals, food and other polymer bottles` surface. Marking effect is fine, clear andsolid, which is better than the injekt printing and no pullution produced.Also used in marking and dicing flexible PCB board, drilling tiny hole or blind-hole on silicon wafers, two dimensional coding on LCD, glass container surface, metal surface coating, plastic keys, electronic components, gifts, communication equipment, construction materials Principle of UV laser marking machineUV laser processing is achieved by photochemical ablation.Strong energy of the laser can interrupt the bonding between atoms or molecules and transform them into small molecules. Small molecule is easy to evaporate.Features of UV laser marking machine1.Excellent beam quality, smaller focused spot size, ultra-fine marking;2.Since most materials can absorb the UV light, the range of application is much more wider;3.Small heat-affected region, no thermal effects, no burning issue;4.High speed, high efficiency;5.Stable performance , small size, low power consumption
