Q:What are the differences between reflective paint and reflective membranes?
The reflection coefficient of reflective paint is relatively low, while the reflective membrane is capsule type which can last for a long time.
Q:It the plastic wrap breathable?
It is not breathable. Plastic wrap principle: 1. Prevent water evaporation, and play the function of sealing; 2. Prevent loss of the original flavor of food in storage; 3. Isolate air, and prevent food oxidation (or infection).
Q:Where are geotextiles and geomembranes usually used?
Geotextiles are usually used to protect roads and slopes and moisturize riverways. Geomembranes are usually used for seepage control of landfills, cesspits, oil tanks, etc.
Q:What are the specifications of moistureproof membranes?
Common moistureproof membranes include wallpapers, coating layers, plywood. Professional moistureproof membranes are developed by water technology which are harmless to the human body and the environment for no volatilization of polluting gases. Comparing with the traditional oil alkyd varnish, it effectively protect the indoor environment.
Q:What are the techniques of foam concrete?
With unique foam excitation technique, coal ash and other waste materials are mixed together in a scientific proportion, then they will become gold bricks—high-performance building blocks which can float on water with many advantages of lightweight, environmental protection, energy-saving and thermal insulation after going through many techniques of compulsory stirring, activation, foaming, output, casting molding. Special foaming agent is composed of several chemical raw materials in a certain proportion that are easy to buy. It will become light after foaming which is much more effective than that of most foaming agents sold in the market, but the price of it is 50% lower than that of most foaming agents sold in the market. High efficient curing agent is composed of several chemical raw materials in a certain proportion that are easy to buy, which greatly reduces cement quantity and cost. It has advantages of high strength and light weight, and enables non-autoclaved blocks (bricks) to reach and exceed the required strength of steam-cured blocks; MS innovative forming non-autoclaved blocks new molding technology, moulds can arbitrarily change the size of blocks in order to adapt to fit around the block sizes that walls need, which reduce the cost of moulds, and are convenient.
Q:How to install the piamater ceiling
(1) For where need to install a soft place, to fix the PVC bracket supports (The support materials can be wood, aluminum alloy, stainless steel or other). 2 Then the PVC keel corner horse nail or nail fixed on the support, and then Darphin special in the knife to cut the film is fixed on the PVC keel bracket
Q:What is the classification of film resistance?
Thin film resistor is different from the thick film chip resistor and the latter dominates the market. It is a thin film chip fixed resistor with high accuracy and low temperature coefficient which is made by evaporating a certain resistivity material on the surface of the insulating material. It can be divided into: 1. Carbon film resistors 2. The metal film resistors. 3. Metal oxide film resistors 4. The synthetic film resistors.
Q:Is electrothermal membrane electric heating blanket useful?
Electrothermal film heating kang is easy to use, the electrothermal film heating system differs from dot mode heating system represented by radiator, air conditioning, heating radiator system, line heating systems represented by heating cable, and LC supply heating high-tech products developed by modern aerospace flight technology.
Q:What is the operating principle of wet membrane humidifier
Wet film humidifier is an isenthalpic humidification way, moisture evaporation are realized by absorbing the energy in the air, then air dry bulb temperature decreased, and the absolute water content in the air increased, but air enthalpy value remains unchanged.
Q:What are the precautions for the construction of the slope area of the cesspit?
The construction method of geotextile/geomembrane: 1 flatness: ±2cm/m2, flat and straight; 2 compactness: 95%, after grinding, pave geomembrane on the surface; 3 vertical and horizontal gradient: Longitudinal and transverse slope should be above 2%, boundary and structure of the landfill bottom must be beneficial to diversion of leachate; 4 cleanness: No roots, rubble, gravel, concrete particles, such as sharp edges shall appear within vertical depth of 2.50cm . Climate requirements while paving: 1. Temperature: 5 - 40℃ is appropriate. Taking into account thermal expansion and cold contraction of the geomembrane, according to experience, when the weather is cold, geomembrane pavement should be tight; in hot weather should be loose; but it should be noted that, in summer, high temperature should be avoided at noon. 2 wind and rain: If the wind scale is over force 4 wind or it's raining, the construction should be stopped; When wind is lessened, it is proper to hold down geomembrane with sandbag so as to facilitate construction. Construction and installation of HDPE geomembrane: 1 construction and installation process of HDPE geomembrane. 2 tailor and transportation: According to the records of laying base measurement , cutting large bundle number of geomembrane should be marked and recorded and then carried to construction site according to their number.
