Flexible lift gate is a flexibel soft curtain door, inside and outside the two curtains , curtains used between the aluminum beams connected with a vertically movable rail , the roof beams have levels not in the same straight line and hanger large plants in particular Be applicable , Flexible lift door installation does not take up interior space in the hole inside , When the first move to open the door , and finally superimposed over the hole , Off event curtain rail first and then fall down until its is completely closed
Door body composition :
The bottom of the door curtain rail aluminum beam beam seal top drive system and transmission of electrical control systems and safety devices
Flexible door features:
1. Light weight compared with other types of the same size door , flexible door lighter weight reduces the strength of steel at the top of the doorway architecture degree requirements ,
2. Small compared with the same specification of the machine style doors 2, footprint ,flexible installation in the door after the hole is turned on internally stacked above the hole , do not take up interior space , Large Span hole may be provided a plurality of movable rail the entire door into several independent stacking doors shorten the span of a single door so that the overall thickness of the door is reduced , further reducing the footprint
3. Rational layout flexible doors with movable rail rail can set different activities based on the specific circumstances of the door into the door several sizes of uneven accumulation of doors to make the building as a whole rational layout greatly reduces the overall architecture of the space and cost
4. The wind strength between two layers of high flexible door curtain as the bottom of an aluminum beam has a wind skeleton steel structure , By adjusting the beam thickness and spacing , which can resist wind pressure of any intensity , so the door can be flexible for use in any area
5. The tensile strength of the flexible door after door curtain is double polyester fabric , high tensile wire rope equipped with ultra-high hole suitable for large machinery such as aircraft hangars and repository
6. The curtain coated with vinyl coated with a waterproof sunscreen and smoldering performance , capable of sound absorption retardant insulation mildew proof and so on
7. Safe door , Cube with anti-lock break to ensure safety in case of accidental breakage of wire rope jammed in the door quickly experience anywhere rails , Multiple protection features mechanical and electrical installation to ensure t he safety of goods passing aircraft and other vehicles and personnel , the movable rail is also equipped with anti-fall device , you can ensure reliable parked at the top of the hole after the movable rail is raised without falling , The bottom of the door is equipped with and airbag , it will immediately rebound to rise until the safety door drops open when obstacles encountered in the process , You can also install infrared protection device on the door

Summary of use Summary of functions
It is mainly applied to the measurement of the whiteness of objects or powders with non-colored surface smoothness, and can accurately obtain the whiteness value consistent with the visual acuity. For an object that has been treated with a fluorescent whitening agent, the whiteness value after the fluorescence enhancement can be quantitatively reflected. The paper's opacity can be accurately measured. Can be widely used in textile printing and dyeing, paint coatings, chemical building materials, paperboard, plastic products, white cement, ceramics, enamel, talcum powder, starch, flour, salt, detergents, cosmetics and other substances whiteness measurement.
