Cars, motorcycles, bicycles these are indispensable in our lives, everyone will be exposed to, these vehicles are using tires, and tires are inflatable way method of use, there must be airflow in the tire to be used properly, and also must meet the standard air flow. Rubber boat manufacturing kayak materials are: wooden plywood, plywood, aluminum, fiberglass, plastic, etc. Internationally, there are uniform regulations on the length, width and minimum weight of race boats to facilitate fair competition. Within this regulation, the manufacturer plays its design level to make the athletes get good results in the race as much as possible. Of course, winning or not, mainly comes from the flexibility of the athletes' skills and the play of power. Inflatable products will have a common phenomenon, that is, the natural air leakage, so we often have to car, motorcycle, bicycle tires for regular inspection, it is best to check once before each drive, to see if there is a lack of airflow, if the shortage also needs to be supplemented in a timely manner, this situation is normal. Rubber boats are also inflatable products, the same will naturally leak, but also to regularly check the inflatable, the specific rubber boat how long to fill a gas also depends on the situation.

Natural air leakage is normal, the normal range is how much, we all say that the water is impermeable, and airflow is more powerful than water, truly impermeable, inflatable products can not guarantee to do absolute airtight, but there will be a standard, the normal rubber boat it natural air leakage is to be very small, may be a few days or a dozen days or even a month before there will be a little obvious airflow loss phenomenon, which is normal . The assault boat, also known as the Dinoa assault boat, or Dinoa barge assault boat, is a kind of inflatable boat, according to the world Guinness Book of Records, the history of inflatable boats can be traced back to as far as 880 BC, the Assyrian II king ordered troops to constantly inflate the skin of the animal, so that it can be inflated to pass the river! In ancient China, during the Song and Ming dynasties, people also used sealed inflated animal skins to cross rivers. And non-normal means that within a day there is a significant loss of airflow phenomenon, that is not normal, which indicates that there is a part of the hull pinhead leak or air valve damage, you have to promptly check the repair to do.

Rubber boat how long to fill a gas is variable, because each boat is different, such as the newly purchased boat and the use of a long time boat is not the same, the material quality is good and material is different, the production process also has a relationship, the production of good to have better airtight performance, the simplest way is to regularly check, the regular period for the best 3 days, but it is best to check once before each use. The way to check is to pinch with your hand, the hard state indicates that the airflow has not yet obvious loss of phenomenon, if some soft soft is to replenish the airflow.

Temperature difference will also make the rubber boat airflow loss phenomenon, rubber boat use (use) is a polyvinyl chloride material, PVC material will change according to the temperature, the temperature is low, the surface of the hull material will harden, material hardening when the inflatable will not expand very much, and high temperature material will become soft, airflow inside the air chamber will squeeze to make it more expansion, at this time the space inside the air chamber is bigger, so there is a lack of airflow This is also a normal phenomenon.

One important point is also about the temperature difference, said above, the morning temperature is relatively low, this time to the rubber boat inflatable must not be too full, you do not want to wait for the temperature to rise material softening will return to normal, which is wrong. The morning airflow is too full to the midday temperature rise, the material becomes soft, the airflow inside the air chamber is too full pressure will be very large, the air pressure will also produce more pressure as the temperature rises, too full easy to squeeze crack rubber boat, so we must pay attention to, generally each air chamber sufficient ninety percent air flow (unit: cubic meters per second) on the line.
