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:Water heater hose 4 points and 6 points difference

4, in charge of 1/2 inches of pipe, 6 in charge of 3/4 inches of pipe, different specifications of some differences.The so-called 5 turn 4, should be different diameter, that is, pipe and pipe joints, parts of different specifications.A bellows is a pipe, not flat, corrugated.

Q:What should I pay attention to when rubber tube is in storage?

Storage should be as follows: (1) should be stored in a ventilated and dry environment, the relative humidity of the air is 50% ~ 80%. (2) should be stored in non corrosive media, and away from the heat source, the temperature is about 5 degrees Celsius conditions. (3) packing should be kept as far as possible without box stacking.

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:How do the rubber tubes fit into the galvanized pipe?

If the rubber tube is outside the galvanized pipe, when the rubber is ordered, the inside diameter shall be greater than the outer diameter of the galvanized pipe. If the rubber tube is inside the galvanized pipe, when the rubber is ordered, the outer diameter of the rubber pipe will be galvanized and the inner diameter of the galvanized pipe will be inside

Q:Automotive applications of rubber hose

Mainly connected to the engine and air filter, engine and radiator systems, automotive air-conditioning systems. As part of its intake from the engine, close, so high temperature resistance, oil resistance, corrosion resistance, aging resistance, low temperature resistance, the material has many types according to the different processing techniques, such as NBR nitrile rubber is widely used in vacuum brake pipe, good oil resistance rubber content is high, but relatively resistant to ozone poor;

Q:The difference between silicone tube and PVC tube

PVC pipe is made of polyvinyl chloride resin and stabilizer and lubricant with injection molding machine with hot extrusion molding, main performance, electrical insulation; chemical stability; self extinguished; low water absorption; easy adhesion, high resistant to high temperature of about 40 degrees. Main appliances, industrial gases, liquid transportation, household sewer pipes, water pipes and so on. Environmental issues: plasticizer, antioxidant and other added accessories are toxic, daily in PVC plasticizer, mainly using terephthalic acid two butyl phthalate two formic acid two ester etc., these chemicals are toxic.

Q:How to determine the tensile strength of GB rubber joint?

The cutting of sample can be done by punching machine. When punching sample, the following points should be paid attention to.The cutting force is uniform, not too large, and with mild soap and water and clean tap water wet specimens (or tools), if a sample cut down, it should be abandoned, not to repeat the old mark for cutting.The direction of specimen cutting should be consistent with the direction of tension and the direction of rolling.

Q:Does the rubber tube affect the engine in the car's tank?

I don't know what you mean by that, but the car's tank itself needs to be sealed and no clutter is allowed

Q:What about leakage of hose joint?

First, the water source is cut off, then the male and female nuts which are connected with the compression joint are removed, and a plurality of threads are screwed on the thread to seal the rubberized fabric, and then the connector is re assembled.
