External wall insulation material which is good, external wall insulation materials
Advertisement is here! In fact, the so-called fresh air ventilator is a conceptual product. Ventilation function is very limited, that is difficult to achieve the effect of exchange air. As to say that the answer is more efficient and nonsense. Said the ventilation is limited, because of its small import and export, the amount of ventilation at the end. At the same time the indoor outlet can not guarantee the dirty air away. Said the heat exchange, you can imagine, indoor and outdoor air temperature difference will be more than ten degrees only in a small exchange area and a very short exchange time, in order to replace the hot air into the indoor temperature near the cold air , There is no material to do now.
Feeling the effect of such lights is greater than the application, really is not in the use of the car, the flexible fiber is generally the car lights or position lights, light time is short; home decoration to long bright, LED on the ruthless Some of the The new light guide itself is fixed, the greater the power of the LED, the lighter the optical fiber, but the need for high-power LED heat, so when you install the attention, low-power LED if you can make light guide you The effect is not good, you need to choose to choose high-power, you have to consider to LED cooling, heat is not good, then said in front of the light failure, secretly secretly Empty Are very simple, do not worry
Indoor insulation material that the best, fire, environmental protection, good insulation effect? ??Glass fiber. Good insulation. Glass fiber cotton with numerous fine gas holes, fibers arranged irregularly arranged, heat conduction breakdown of 0.03w / cm.k, is an excellent insulation material; . with non-flammable. Glass fiber cotton will not burn, no deformation, no embrittlement, can withstand 700 degrees of high temperature, the combustion performance to A1; . environmental non-toxic. As the glass fiber cotton in the manufacturing process does not add any adhesive, so there is no smell, high temperature will not be distributed when the toxic, pungent smell, smell, etc .; . high insulation. As the glass fiber cotton used in the raw material is glass, non-conductive, so it has a very high insulation; . corrosion resistance. Glass fiber is not afraid of strong acid, with a strong corrosion resistance, even if the use of long time will not reduce its functional characteristics; . good recovery Glass fiber contains numerous fixed cavitation, with excellent recovery, not afraid of any shock, tensile strength are more than 1.0kg; . do not want to light field scrambled decanoate containing mutual water. The moisture absorption of glass fibers is usually close to zero, do not worry about there will be water swelling caused by wet cracking of the situation. I hope my answer can help you.
