- Q:What are the specifications of the reinforced glass fiber?
- The unidirectional geogrid according to different materials is divided into one-way polyethylene geogrid and PP unidirectional geotechnical grille. According to the tension of different TGDG30KN TGDG40KN TGDG50KN TGDG60KN TGDG80KN TGDG90KN TGDG100KN TGDG110KN TGDG120KN TGDG150KN TGDG200KN until TGDG260KN
- Q:What are the standards of geotechnical test methods?
- Common standards and codes related to geotechnical tests are as follows: (1) the railway engineering geotechnical test method "(TBJ102-96) (2) the geotechnical test method standard" (\ t50123-1999) (3) "road geotechnique test procedures" (JTJ051-93) (4) the water conservancy geotechnique test procedures in the "(SL237-1999) (5) the railway subgrade construction specifications, TB10202-2002 (6) the highway roadbed construction technology standard" JTJ033-950 geotechnical test in the regular program. (1) water content, density, proportion; (2) analysis of the particle size , liquid limit, plastic limit; (3) maximum density and minimum density of sand; (4) compaction test, bearing ratio test.
- Q:What are the specifications of the finishing protective film?
- PP transparent protective film:1m wide * 30m long, thickness: 1mm；Pvc plus cotton: 1.2m wide * 40 long, thickness:0.5cm; Expand Aple Poly Ephylene protective film: 1m wide * 100m long, thickness can be customized according to customers'requirements.
- Q:how to do when the film wrinkling
- Usually the problem is risen because the first paint is not dry then brushing the second time . Then the lower paint solvents will affect the upper membrane and make it wrinkled. in this case, it is available to use mercury chemical agents or heating the film to remove wrinkles, then re-painting. Remember, you have to wait for the first painting drying and then brushing the second time.
- Q:What is the material of HDPE geomembrane?
- The main materials: High density polyethylene should match color master batch. Double resistant HDPE
- Q:How to remove the protective film of the guard against theft?
- 1: The area is not large and you can use banana water to soak it and then clean it with a cleaning ball. 2: It can be removed with cleaning agents (bottled called A1) used in the textile industry.I have tried. It is very good. 3: To add some sulfuric acid into the water, otherwise it will be corroded and then rub with the cleaning ball. 4: To heat it with the electric hair drier, or with a wooden shovel, plastic marks can be used to wipe off the solvent oil
- Q:What are the advantages of the glass reflective film?
- Reduce glare for extra comfort. It can block more than 99% of ultraviolet rays. It can make you fully enjoy the sun while prevent the family from glare and ultraviolet harassment. Its specific anti-scratch coating can make the film more durable in use. It can prevent the furniture from fading in color and reduce the high cost of air conditioning. It is energy saving and environment friendly, and can reduce the high electricity bills caused by air conditioning and heating. It can deaden ultraviolet rays intrusion, and protect indoor objects from fading in color and aging. It can filter hard light and reduce glare, and protect the skin and vision. It can increase the glass strength, reduce personal injuries and protect property, and build invisible protective screening. With one way vision and privacy protection, it can make you enjoy cozy, quiet and comfort in your living space. Improve the architectural appearance and beautify the indoor living environment. It is easy to paste and clean, and friction resistant without the need of special maintenance. It is economical and practical, and doesn't fade in color with no bubbles and long service life.
- Q:Is silicon crystal electrothermal film heater good?
- Silicon crystal electrothermal film heater is good. Silicon electrothermal film heater is one of the most popular heating device in recent period. Its working principle is that the inorganic electric conduction membrane made by silicon materials will form hot air curtain, heat convection and far infrared thermal radiation to heat. The volume of this heater is smaller than electric oil heater embodied with all characteristics of the above heaters. And the appearance is like flat plate, more fashionable and more in line with modern people's aesthetic view. Unlike fan heater including sun heater, silicon electrothermal film heater heats up fast and even, has strong ability to resist failure, without electromagnetic pollution due to flat heating. Compared electric oil heater, it has certain advantages in terms of heating speed and energy conversion efficiency. So recently it has become more and more popular.
- Q:Does computer screen need to stick film?
- Paste, the LCD screen will produce static electricity, so it is easy to absorb dust. We can't wipe the screen with tissues every time because there will be polishing scratches on the screen for a long time. It is simple and convenient to wipe directly on the film after sticking the film. which will not affect heat dissipation.
- Q:What are the capping and the foot care of the the three geomembrane grass?
- Is the construction of the anchoring ditch similar to the geotextiles?
