Tanker owners can learn from the “Regulations for the Implementation of the Road Traffic Safety Law †that when the tanker is travelling in some special circumstances, the maximum driving speed must not exceed 30 kilometers per hour, including tractors, battery cars and wheeled vehicles. The mechanical vehicle must not exceed 15 kilometers per hour. Tankers shall indicate the driving speed of the lane on the expressway. The maximum speed shall not exceed 120 kilometers per hour, and the minimum speed shall not be less than 60 kilometers per hour. The maximum speed of a small passenger car traveling on a freeway shall not exceed 100 kilometers per hour and motorcycles shall not exceed 80 kilometers per hour. If there are two lanes in the same direction, the minimum speed of the left lane is 100 kilometers per hour; if there are more than 3 lanes in the same direction, the minimum speed of the leftmost lane is 110 kilometers per hour, and the minimum speed of the middle lane is 90 km. If the speed limit indicated on the road speed limit sign is inconsistent with the above-mentioned lane speed, the speed shall be the same as the speed indicated on the road speed limit sign. After driving for more than owners of medium-sized passenger vehicles, dangerous goods transport vehicles more than four hours a rest stop or a rest stop not less than 20 minutes are called "fatigue driving," driver fatigue is the only driver in the long hours driving , resulting in the imbalance of physiological function and psychological function, but in reality the phenomenon of declining driving skills. Drivers have poor or insufficient sleep quality and are prone to fatigue when driving vehicles for long periods of time. Driving fatigue affects the driver's attention, feelings, perceptions, thinking, judgment, will, decision and movement. If you continue to drive your vehicle after fatigue, you will feel drowsy and sleepy. Your limbs will be weak, your concentration will be inconspicuous, your ability to judge will decline, and you may experience mental paralysis or momentary memory loss. This may result in late or premature movements, improper operation, or improper correction time. As a safety factor, it is highly prone to road traffic accidents. Therefore, it is strictly prohibited to drive vehicles after fatigue. Sodium Tripolyphosphate, Na5P3O10, Molecular weight 367.86, white powder; Melting point 622 °C. free soluble in water, aqueous solution appears ACID. It has got salient chelating capacity to metal ions of Ca and Mg etc. and can soften hard water to make suspension into solution, alkalinity, without causticity. It is an inorganic compound with formula Na5P3O10, is the sodium salt of the polyphosphate penta-anion, which is the conjugate base of triphosphoric acid.Sodium tripolyphosphate is produced by heating stoichiometric mixture of disodium phosphate, Na2HPO4, and monosodium phosphate, NaH2PO4, under carefully controlled conditions.

It has different bulk density, i.e. low density 0.35-0.6g/cm 3 , medium density 0.6-0.8g/cm3 and high density 0.8-1.0g/cm3. This product has two crystalline forms, namely phase I (high temperature phase) and phase II (low temperature phase). The chemical properties of the two phases are the same, and the difference between them lies in the thermostability, hygroscopicity, solubility and hydration heat when dissolving.
It can be used as one of the main auxiliaries for synthetic Detergent, synergist for soap; water softener, tanning agent for leather making, auxiliary for dyeing; As an effective dispersion agent for suspensions of coatings, kaolin, magnesium oxide, calcium carbonate and drilling mud etc.
As an oil contamination resistance agent in paper production; As in foodstuff industry it is used as quality improver in the process of canned food, fruit juice drinks, foodstuffs from milk or soybeans. It may tender the meat in canned ham and soften the skin of horse bean in canned horse bean. It may also serves as a softener or densifier in foodstuff industry.
Tanker manufacturers to analyze the speed limit and fatigue driving requirements of tankers
Tanker owners all know that when a motorized vehicle such as a tanker drives more than 50% of the prescribed speed, it will be fined between 200 yuan and 2,000 yuan:
