Q:Do 3cm thick wall insulation how much kilogram of slurry and how many kilograms of polystyrene particles
You are talking about the construction measures it is not the house measures it, because the house has a construction of Huohuohuohuo number of leather and bronze sculpture drawings and specifications, high-rise building scaffolding should be lightning protection measures, that is, under the scaffolding around Reliable grounding (not less than four times, not less than 16 square copper core BV line), if it is pick plus, and the house can be connected to the pressure ring. Tower crane I will not say, upstairs has been said.
Q: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 High
Q:Home 2 air conditioning is the cooling of electricity or heating electricity? How much power is spent in hours
Common scaffold brace is the U-type care, "construction of fasteners steel scaffolding safety technical regulations" (JGJ Gong Gong Duo Ji-tao pan Revenge two 130-2011) provides "adjustable support bearing capacity design value is not Should be less than 40kN, the support plate thickness should not be less than 5mm ", the general calculation using 30kN.
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: kfwdz@hotmail.com
Q: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.
Q:Air conditioning machine work when the sound is too much reason
This is based on the density of benzene board decision, not what you said, know it buddy.
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: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: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:Air to water heater host and air conditioning host is not the same
Issued a test report, Detection can be used to pass, failed to use!
