Using the good insulation effect of sound insulation cotton, it can effectively avoid the high temperature of the engine to the hood directly after paste in the car cover, thereby protecting the hood surface car paint while avoiding the foggy fog affecting the sight of the hood.
Harm of sound insulation cotton
Because sound insulation cotton is made of asbestos.This is also the sound insulation filling material that almost all the general intervals will be selected.The damage to the human body is very large. Because its fiber is very thin, it is easy to inhale. The most direct is that it will cause lung disease and lung calcification.And its impact is not exposed in a short period of time, and it is usually slowly accumulated in such a long -term process of ten to 20 years.In fact, everyone does not know that asbestos is harmful, but there is always luck. I think everyone does that, and they can do that.hehe.In the past two years, buying a house and decoration seems to be a peak period.Then ten years and twenty years, I am afraid that a large number of people will be relatively concentrated or even die.Those who often come into contact with such materials may be obvious.
Sound insulation cotton installation
(1) Paste the fireproof sound insulation cotton at the launch of the cabin cover. The sound insulation cotton can absorb the noise when the initiator is running in large quantities, and it also has the heat insulation function.Essence(2) Add vibration -reducing sound -cutting pads and waterproof sound insulation cotton+shock -stop pads on the central chassis and rear compartment chassis in the carriage. Its main role is to alleviate the central chassis and luggage under the chassis and luggage.The resonance caused by vibration reduces the pavement noise transmission caused by the rotation of the tire, and the resonance pressure of the rear carriage from the exhaust sound is reduced from the sound of exhaust sound.(3) Paste the buttl rubber and sound insulation cotton inside the door trim. It can reduce the resonance of the door sheet metal constructor during driving, reduce the loosening of the door interior board and parts, and reduce the cause of the car due to the car.Older or long -term driving in bumpy pavement, the murmur caused by metal fatigue and the body twisting.(4) Put a layer of sound insulation cotton in the inner side of the door of the door, paste the inside of the door panel, and install the door dense seal to enhance the sealing of the door and the door frame.After such construction, it can not only enhance the rigidity of the door and reduce resonance, but also effectively reduce the wind noise of high -speed driving in the car.
What brand of sound isolation cotton is good
1. Daineng car sound insulation cotton 2. Thunder car sound insulation cotton 3. Strong cars sound insulation cotton 4. GVP cars sound insulation cotton 5, MST car sound insulation cotton 6, Baojing car sound insulation cotton 7, Jingya car sound insulation cottonSound insulation cotton 9, K8 car sound insulation cotton 10, Veramid car sound insulation cotton
Sound insulation cotton price
Glass fiber sound -proof cotton is divided into two types: cotton rolls and cotton plates. The capacity of cotton rolls is small. The price of Bofu is only ten yuan per square price as low as a few dollars;The commonly used is 35km resistant and 40km eggplant. The price per square meter is between 15 yuan and 20 yuan.Polyal acid fiber sound barrier is relatively expensive, mainly because of the advantages of polyphenol fiber, new environmental protection, soft touch, etc. The specifications are roughly the same as the glass fiber soundtrack cotton.Essence
Is sound insulation cotton useful?
Principles of sound insulation cotton: Object vibration generates sound → sound waves are transmitted in the air → cotton has a multi -fiber structure → sound waves are reflected, overlapping, collision with countless fibers when cotton, and the sound wave energy is converted into thermal energy → sound wave strength weakens → sound disappear.Another role of sound insulation cotton is the heat insulation, which can reduce the heat from the surface of the engine to the surface of the hood, and the vehicle with a hood soundtracking cotton is basically no white mist during rainy days.On rainy days and winter, due to the large difference between the external temperature and the engine temperature, coupled with the common effects of rainwater such as rainwater, it will accelerate the oxidation of the paint surface.
