Q:What are the structural features of the sealing device of the floating roof tank?

The elastic sealing material is mainly composed of a rubber belt, soft foam blocks, supports, pallets and fasteners and other components, the soft foam blocks it depends on a rubber band wrapped up, filling in an annular gap between the floating roof and tank wall and form a seal.

Q:How to clean rubber band?

Rubber Strap Black, how to clean yellow, mostly because of quality problems, if your watch is brand name, but still yellow, that means that you own improper cleaning methods. When washing the strap, use the soap or washing powder to meet the dermal part and clean with toothpaste. After washing, remember to rinse the remaining foam thoroughly and dry it with a dry towel. Remember to stay out of the sun. If the sun is too strong, you can take it out and dry it in the evening. This is my own experience. I hope I can give you some help

Q:What do you call a machine that folds rubber bands into a stamp?

These more complex machines are usually called machines. From the point of view of the structure and motion mechanism and machine, there is no difference between general machinery. Machinery, derived from the Greek Mechine and Latin Machina, originally referred to as "ingenious design", as a general mechanical concept, can be traced back to the ancient Rome period, mainly in order to distinguish between hand tools.

Q:What's the rubber band on your wrist when you play basketball?

Q:Why are the engines almost all rubber belts?

All kinds of driving methods have their own advantages and disadvantages.Sprocket, chain drive - transfer speed is limited.Gear transmission --- the transmission distance is limited and the noise is great.Belt drive - smooth transmission, quiet, easy to implement, low cost.

Q:White rubber strap dirty, how to do?

Now clean the strap. Clean the surface of the strap first, then clean the stain in the band gap. The gaps are so tight that it's difficult to clean the dirt inside. Now the gaps are opened up by the cylinder, and the dirt can be cleaned.

Q:What should I pay attention to when the belt conveyor is setting the brake?

At the end of long distance conveyor safety brake set, because the load of belt conveyor is in the entire transportation line began distribution, and the tension of heat resistant rubber belt, generally can not carry out safety braking, so we can reduce the speed of conveyor system from the mechanical system of downtime, avoid dynamic load a large and accurate pattern shape material on the conveyor belt does not slip in the case of herringbone.

Q:Why is the watch of rubber band more expensive than resin?

PS: rubber contains a variety of ingredients, a pungent odor, some of which may have an impact on human health, so generally contact the skin and long-term contact will use silicone.

Q:What is the essential difference between the effect of electric tape and rubber band?

A different component: PVC electrical tape is the pressure-sensitive adhesive evenly coated PVC membrane made of high pressure; self-adhesive tape is made of rubber, oil, calcium powder and other ingredients and pressing; black tape is made of cloth, asphalt and other components of rolling.Secondary sex can be different: electrical tape resistant to temperature generally 80 degrees, high pressure self-adhesive tape, high temperature resistance of up to 150 degrees; black adhesive tape is generally used in low temperature environmentThree, the role is different: PVC electrical tape for 70 degrees C below the temperature environment, 600 volts and below wire and cable insulation insulation, acquaintance, color separation, sheath protection, wiring harness and so on. It can also be used for binding, fixing, lapping, mending, sealing and protecting in industrial process.Features: smooth or foggy surface, soft base, rich elasticity and high mechanical strength, good adhesion and electrical insulation performance.The high-pressure self-adhesive tape for 80 degrees below the temperature of C environment, used for insulation protection wire and cable terminal and intermediate joint of 1KV - 10KV, insulation is widely used in communication cable joint, protection, repair and seal pipe.Features: economical universal rubber belt, which has good self adhesion. It is integrated in the insulation layer and never falls off. It has better sealing performance.Four, the price is different: PVC electrical tape in less than 10 yuan, and high pressure rubber self-adhesive tape, high price, cost is 10-30 yuan a roll

Q:How about white rubber strap yellowing?

Rubber: the word "rubber" comes from the Indian language "cau-uchu", meaning "weeping tree"". Natural rubber is flowing out from the Hevea latex when tapping after solidification and drying process. The finished product is material with elasticity, insulation, waterproof and air.
