Production Flow

   




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: Air conditioning ventilation when the sound is a big reason
No matter, it is best to cut the distance between the material and the roof, like an arbor. Otherwise it is not foam board with it
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: I added the space 18 degrees opened for 5 hours or not cold, we all know how is it? More
The general level of more than 12 layers when you need to use.
Q: Air conditioning machine work when the sound is too much reason
Many of the good quality of the model, of course, bear some of the larger. Common scaffolding brackets are U-type care, "construction fastener steel scaffold safety technical regulations" (JGJ130-2011) provides "adjustable support bearing capacity design value should not be less than 40kN, support plate thickness should not be less than 5mm ", the general calculation using 30kN. Not to say how fast buckle steel scaffold can bear the load, but according to how much load to calculate how scaffolding erection. Need to be calculated. In the "construction of fasteners steel scaffold safety technical specifications" provides instructions. Double fastener (anti - skid) bearing capacity design value 3.2KN. Right angle fastener, rotary fastener (anti-skid) bearing capacity design value 8KN.
Q: What is the whole heat exchange fresh air ventilator?
(GJG130 - Fan Jutang Duanjie Daojie Juejiao 2001) will be replaced by (GJG130-2011) is expected to begin the implementation of the construction of this year, the construction of fastener steel scaffolding safety technical specifications (GJG130), the construction of fastening steel pipe scaffolding safety technical specifications (GJG130- -2011)
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: 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 objects
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
Normal heat absorption is also due to poor ventilation (dirty) and air humidity so icing
Q: HVAC Heating: What are the main components of the air distribution system?
Geothermal construction, the heating pipe spacing can not be less than 100mm, the construction can not be achieved, big brother!
