Production Flow

PVC Aluminum Flexible Duct

Q:Such as the problem, and now air-conditioning technology is mature, the market a lot of air conditioning are cold and warm, and I would like to be able to put my home that the end of the century loaded Mitsubishi air conditioning (split single cold) into a cold Before the conversion of ordinary TV to the remote control, that air conditioning can be modified? How much does it cost? Where is this technology? More: External wall insulation should pay attention to what the details?

Q:In the design, the building structure and the hydropower are generally designed by the Architectural Design Institute. The air conditioning ventilation is based on the design of the room. Or first air conditioning ventilation? More: Polystyrene should not be polycyclic aromatic. Polycyclic aromatic groups generally refer to aromatic groups when multiple benzene rings are used. Not all of the hydrocarbon chemical products are carcinogenic, and our bodies are producing hydrocarbon compounds all the time. Polystyrene carcinogenicity is small. General benzene ring on the more substituents, the toxicity is relatively small, such as toluene is less than the toxicity of benzene. Of course, there are many compounds with benzene ring, so there are a lot of scholars to study with our body creatures do not meet the quality of raw materials to do the polymer, such as lactic acid production of polylactic acid, but the current Can be put into use much.

Q:I added the space 18 degrees opened for 5 hours or not cold, we all know how is it? More: 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 High

Q: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.

Q:HVAC Heating: What are the main components of the air distribution system?: (HS Code) Yes, the tax rebate is 13% (April . 2009 latest data). Floor of the board of the tax number is, the tax rebate is 9% (June . 2009 the latest data), floor board is the inspection of goods, exports need to be checked. There is nothing to understand where to add me MSN:

Q:US direct mail dysonhp01 Dyson air purification cooling machine triple in the country to warranty it: Among them, the extruded polystyrene gypsum composite board is based on paper gypsum substrate, the use of adhesive and extruded polystyrene board through the factory processing compound

Q:Do 3cm thick wall insulation how much kilogram of slurry and how many kilograms of polystyrene particles: Of course, is heating electricity. Heating has auxiliary electric heating, so electricity and electricity. Frequently open the fee, the air compressor is not good. 2 machine cooling power is 1700 watts, 1 hour is 1.7 degrees electricity. Heating with auxiliary electric heating power of 1500 watts, 1 hour is 3.2 degrees electricity.

Q:Ventilation is very good, why still have to install fresh air system: You are a single raft toilet wipes Pie Tanzhuang open card would like to confirm what? Contract notarization or. The The If it is contract notarized, generally notary value of 0.25% -0.3%

Q:The installation method of ordinary air conditioner. The more detailed the better. Please thank you all: The basic operation of the same, but the different requirements of different professional, or to determine the direction of good, and then hands.

Q: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 15
