Q:Is the hot air gun can be used to weld the composite geomembrane?
The composite geotechnical membrane is generally welded by the as the special geotechnical membrane welding machine for welding hand - held hot air gun area of repair holes suitable for geotechnical membrane welding
Q:What are the differences between strong transmittance coated glass and non-coated glass?
High transmittance coating is what we usually said electroplating, which can effectively prevent ultraviolet ray and sun glare, suitable for outdoors, wihle uncoated one is suitable for indoors and during night.
Q:What are the technical parameters of unidirectional geogrid?
Unidirectional geogrid can be divided into two categories according to material, namely the unidirectional polyethylene geogrid and unidirectional polypropylene geogrid. It can also be divided according to tensile force, namely TGDG30KN, TGDG40KN, TGDG50KN, TGDG60KN, TGDG80KN, TGDG90KN, TGDG100KN, TGDG110KN, TGDG120KN, TGDG150KN, TGDG200KN. At present, there are two standard for geogrid, namely the national standards and industry standard of Ministry of Communications. The former is for the product of integral stretching geogrid. The latter is for the product of various kinds of geogrid. You can check the two standards.
Q:How to adhere film to the glass window?
A. Preparatory work and installation of architectural membrane pasting: 1. Preparations before installation a) Learn the specific conditions of the window to be pasted membrane in detail, and estimate specific items for site cleaning, and the size and quantity of the window membrane needed cutting; b) Determine the construction method according to the window membrane type chosen by the customer and characteristics of the the glass; c) Check whether the installation tools are normal, and check if the "blade" of the water wiper is flat and smooth, and if there is any gap existent. Check if the cleaning scraper knife is sharp, and if there is any gap or sawtooth existent; d) Check if the cleaning and installation towel is clean, if the waterproof membrane is clean and intact; e) Prepare the film-on and cleanout fluid well; 2. Installation of window membrane: A. Advance preparations for the construction site. a) In the construction site, remove the curtains, blinds, and all other objects near the window carefully, and make them go back to the original state when the window membrane installation is completed. Try to leave more space for equipment placement. If the construction site is located within an office or store, please make sure that the cleaning work in advance will not interfere with the customer's normal business operations; b) Do a good job in on-site waterproof and cleaning, laying of waterproof membrane, and work overalls and shoe covers wearing;
Q:What's the ductility of geomembrane?
American standard is above 700% while LDPE geomembrane is over 400%; national standard 1 is more than 450%; urban construction department standard is also above 700%; national standard 2 is more than 550%
Q:How to install soft membrane ceiling in conference room?
Step 1 of soft membrane ceiling installation in conference room: 1. In accordance with the requirements of design drawings, fix a circle of supporting keel (batten or steel pipe) around the place to install soft membrane ceiling. (See construction design drawing).Note: in some large places, you need to install by block to achieve good results. In this case, you need to add batten in between. This depends on actual situation. 2. When all required battens are fixed, install and fix aluminium alloykeel of soft membrane ceiling in the bottom of supporting keel. (See construction design drawing) Step two: 1. When all installation of aluminum keels of soft membrane ceiling are fixed, install soft membrane. First open soft membrane and heat sufficiently and evenly with dedicated heater, then insert the soft membrane into aluminium alloy keel with dedicated slotting tool, and finally cut the surrounding spare soft membrane. (See detailed construction design) 2. After installation, use a clean towel to clean soft film smallpox.
Q:What is the material of the installation technology of soft membrane?
It is made of special PVC materials without cadmium and the fire rating of B1. There is a very good fire performance.
Q:How to tear down polarizing film from display?
The steps of polarizer replacement: 1. Tear down the old polarizer. Problems: It requires specialized equipment, because it needs large and even force, and it can not be completed by hands. 2. adhesive residue cleaning of glass surface. Problems: It needs professional cleanser, and the adhesive residue must be clean up. 3. Stick the new polarizing plate.
Q:Geogrid construction should refer to what norms
At present, there is no special geogrid reinforced soil construction specifications, can refer to the "road reinforcement soil construction technical specifications" in the provision of the belt with the requirements to do.
Q:The concept of HDPE geomembrane
PE has excellent resistance to most living goods and industrial chemicals, relatively large use temperature range (-60---+60) and long service life (50 years). It is aging-resistant and can be used in artificial lake seepage proof.
