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: Do I need a shim for the flat metal hose joint?: If one of the two interconnected joints is one of those with a groove and a O ring, it would be better to put the O ring in it and seal it better.

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: The basic buret is a rubber tube is inlaid with a glass bead to replace glass piston. Why this burets cannot be used to install Potassium Permanganate solution?: It can not be installed, but it does not conform to the standard of chemical experiment operation. Strong oxidizer will damage rubber tube. That's why it's not recommended. Acid burette operating standards have placed solution requirements.

Q: What's the cause of a default like a general rubber product?: Rubber aging is a common problem of rubber products, and aging is mainly due to internal structure or component is easy to aging due to weakness, such as unsaturated double bond, branched, carbonyl, hydroxyl and so on; at the end, the main external or environmental factors are sunlight, oxygen, ozone, heat, water and mechanical stress force, high energy radiation, electricity, industrial gas, water, salt fog, fungi, bacteria, insects etc..

Q: Why should liquefied petroleum gas use strong rubber hose and liner?: Commonly called liquefied petroleum gasMain ingredients: ethylene, ethane, propane, propylene, butane, butene, etc. (oil resistance will accelerate swelling and aging).Appearance and properties: colorless gas or yellow brown oily liquid, has a special odor.In order to remind people of the leakage of liquefied petroleum gas in a timely manner, the processing plant often mixes a small amount of foul odor mercaptan or thioether compounds into liquefied petroleum gas, which is the source of special odor.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!

Q: Production process and raw material of rubber: The relationship between tensile strength and rubber structure: a large force between molecules, such as polar and rigid groups; the molecular weight increases, increasing the fan Edward force, the chain segment is not easy to slip, the equivalent of molecules formed between physical crosslinking points with the molecular weight increased, the tensile strength increased to a certain extent reached equilibrium; microstructure the molecular structure, such as the effect of cis - and trans structure;

Q: Is the installation of submersible pumps mandatory for the installation of flexible rubber joints?: According to the design requirements, choose whether the installation of rubber joints, Kannami Masashige water supply equipment Co., Ltd. is specializing in the production of rubber joint manufacturers, products and technical advice

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: Difference and application of rubber joint and rubber expansion joint: The utility model can be used to reduce the vibration and noise of pipelines, and can compensate for thermal expansion and cold contraction caused by temperature changes. Rubber expansion joints are used in chemical, construction, water supply and drainage systems!
