Do 3cm thick wall insulation how much kilogram of slurry and how many kilograms of polystyrene particles
- From the outside: ① rigid waterproof casing is only composed of steel casing and wing ring, simple structure; ② flexible waterproof casing mainly by: flange casing, seals, flange pressure plate, wing ring, bolts, nuts Composition, complex structure From the waterproof performance up to choose: ① rigid waterproof casing is outside the wing (ring made of steel ring on the steel pipe), installed in the wall (mostly concrete wall), for the general pipe wall, ; ② flexible waterproof casing in addition to the external wing ring, the internal file ring and the like, the flange wire, there are sets of sales, but also their own processing, for the need for shock absorption pipeline, such as and pump connected When the pipe is through the wall In other words, if the wall on both sides of the waterproof performance, it is necessary to use flexible waterproof casing; if only to consider the pipe through the wall, without considering the wall, the wall on both sides of the waterproof performance and displacement of the pipeline deformation You can use rigid waterproof casings
Space blowing wind is not cold how is it?
- Common points are all sandwich panels, with a hard protective layer, the difference is the middle of the different materials, such as polystyrene board, polyurethane board. Polystyrene board which is the most common, because the price is cheap, easy to use so the use of more, but if the temperature is more than the requirements of the chicken inertia glycosylation moxibustion slim faint words, polystyrene board is not satisfied , So there is a polyurethane sandwich panels, polyurethane thermal conductivity of less than 0.. in the existing insulation materials, large quantities of processing, be the best. But because of its process is more complex, and the cost is relatively high, so with less, the common combination of cold storage and the like, I believe that with the economic and technological development, polyurethane sandwich board market share will be more and more Highs
Gree air conditioning 50 heating and cooling mechanism heat when the host cooling network is how the matter
- Can be small, according to your roof to do what material.s
Air conditioning ventilation when the sound is a big reason
- Buried plastic pipe under external load, the diameter of the vertical diameter deformation rate should be less than the allowable diameter of the pipe deformation rate The diameter of the allowable diameter of the pipe shall not be greater than 5% The diameter deformation rate of the pipe and the allowable diameter deformation rate are calculated as follows: ε ΔD / D0 × 100% [ε] ε0 / K where: εΔD pipe in the combined load (Mm) [ε] Permissible diameter Deformation rate ε0 Elastic diameter Deformation rate (%) of pipe, by the flattening of the diameter of the pipe diameter (mm) The test determines the K safety factor, generally desirable 15s
Public building design, the building structure and water is generally designed by the Architectural Design Institute, air conditioning and ventilation is based on the design of the interior? Or first air conditioning ventilation?
- Aluminum alloy metal shell better than the plastic shell; we all know that most of the market is now charging the lithium battery, lithium battery is the only drawback is the possibility of a long time with the explosion, so the use of aluminum Alloy shell, much better than steel; polymer battery is good, but the price is expensive,s
Ventilation is very good, why still have to install fresh air system
- Also known as foam board, EPS board, is containing volatile liquid blowing agent of the polystyrene beads can be preheated by heating, heated in the mold and the formation of white objectss
What is the whole heat exchange fresh air ventilator?
- Second, the new insulation decorative board is integrated through the production line, set insulation, waterproof, finishes and other functions in one, is to meet the current housing construction energy needs, improve the industrial and civil building exterior wall insulation level of the preferred material, but also on the existing Building energy-saving transformation of the preferred materialss
Air to water heater host and air conditioning host is not the same
- This test with a small sample length 127mm, width 12.7mm, the maximum thickness of 3.2mm. In the absence of ventilation test chamber. The top of the specimen (6.4 mm place) is clamped with a clamp on the bracket and the longitudinal axis of the specimen is kept vertical. The lower end of the specimen is 9.5mm from the lamp tip and 305mm from the dry absorbent cotton surface. Bring the Bunsen burner and adjust it to produce a blue flame with a height of 19mm. Place the Bunsen Lights flame at the bottom of the sample for 10s, then remove the flame (at least 152mm away from the specimen) and write down the sample. Burning time. If the flame of the sample within 30s after removal of the flame is extinguished, the original lamp must be moved under the specimen again, re-ignite the sample for 10s, and then remove the Bunsen burner again and note the flame burning And flames burning the burning time. If the sample droplets drip, let it fall into the sample under the 305mm cotton, to see whether it ignited cotton. If the absorbent cotton is on fire, the rating should be taken into account. Specific grading indicators are as follows. Test Item 94V-094V-194V-21 Ten-time ignition Total flame burning time Maximum value (S) Individual flame burning time Maximum value (s) Flameless burning time (s) Yes Flame drop No No Allow only short time Burning general UL yellow card on the thickness of the test strip is divided into: 1/8 inch, 1/16 inch, 1/32 inch thickness, that is, 3.2mm, 1.6mm, 0.8mm three grades test.s
