Q:What is the essential difference between natural rubber and three yuan ethylene propylene rubber?

The strength of natural rubber in the elastic material, natural rubber, rubber, rubber, vulcanized rubber with higher intensity. The tensile strength of uncured rubber is called Green strength, and the Green strength of natural rubber is up to 1.4~2.5Mpa. The proper Green strength is necessary for rubber processing and forming. The tear strength of natural rubber is also higher, up to 98kN/m, and its abrasion resistance is better. The reason for the high mechanical strength of natural rubber is that it is self reinforcing rubber. When stretched, the macromolecule chains tend to form crystals in the direction of stress.

Q:Is the electric water heater well connected with the metal hose?

It's better to use a metal hose.Good resistance to high temperature.In addition, the metal hose is better tolerated.It is more durable and difficult to break than hose.

Q:What is the principle of communicating devices? What if the rubber tube is used as a connecting device to change the water for the fish?

Siphon principle: that is the principle of connected devices, plus in a closed container, the pressure on the liquid, everywhere equal. The siphon is filled with water, there is no gas, the water level of the water inlet is high, and the water outlet is closed with palm or other objects. The pressure is equal everywhere. When all are arranged, the water outlet is opened, although the atmospheric pressure on both sides is equal, the water level at the water inlet end is high and the pressure is large, and the water inflow is continuously flowed out of the water outlet.

Q:What is the high and low pressure circuit of diesel engine?

High pressure oil from the pump to the diesel engine combustion chamber nozzle before that, due to the movement of the piston engine in the process of pressurized environment into the combustion chamber of diesel oil injection so the pressure is high, the combustion chamber is higher than the minimum compression pressure environment stroke made, otherwise the oil can not be sprayed into the combustion chamber. So this section of the road is made of metal.

Q:Excuse me: how can a pen with a rubber tube attract more ink?

Pull out the iron sleeve outside the rubber tube and suck it again and again

Q:What with the appropriate suction tube Dichotomanthes tube and rubber machine

The bellows are extruded by the extruder, and the winding tubes are wound in circles

Q:How long is the service life of the gas hose?

The gas hose is connected to the gas pipeline and special gas hose with / out, according to the number of gas accident statistics analysis, because the gas hose aging or bitten by rats caused by gas leakage accident / Xi accounted for more than 30% of all gas accident.

Q:M40 and M50, and then the hose is 2 "what does the box connection mean?"

This should be called joints, hose connectors or joints or the traditional water tower.

Q:The use of anti slip rubber joints under what circumstances?

Flexible rubber joint is normal for medium temperature water at 0-60 DEG C, such as special medium: oil, acid, high temperature and corrosion resistance and other hard conditions, should use special refractory material rubber joints should be relatively, not blindly on or in general.

Q:Petroleum gas has a corrosive effect on ordinary rubber pipes and is easy to cause air leakage. So, what kind of hose must be used?

These gases on the rubber has a certain corrosion, swelling (not resistant to oil will speed up swelling), aging effect, liquefied petroleum, so choose rubber seal to consider oil resistance, corrosion resistance, swelling.
