In December 2012, the Guina No. 1 shrimp, which was led by Professor Chen Xiaohan of the Guangxi Fisheries Research Institute, passed the examination and approval of the National Commission for the Production of Aquatic Products and became the first new aquatic product to be approved by the state.
In 2005, Guangxi introduced a group of South American white shrimps that represent the origin of five geographic populations from abroad, and established the most abundant breeding pool for South American white prawn. After six generations of continuous breeding, it has cultivated A new high-yielding variety, "Kwai Hai No. 1", was produced in the shrimp of Naribbean. “Guihai 1†showed many advantages such as high growth rate, strong adaptability, high survival rate and single yield, suitable for medium-high density and large-scale shrimp culture, etc., and its breeding performance was better than imported varieties. The average weight at 60 days was 12.6. In grams, the average body weight of 130 days and 150 days was 35.17 grams and 45.46 grams, respectively, which was recognized by the majority of seed breeding enterprises and farmers.
PA6 is recognized as the most widely used and known engineering plastic in the current market. PA6 has the best performance, very tough, even at low temperatures, and high surface hardness, mechanical lower shock, and abrasion resistance. Combined with these characteristics and good insulation, and chemical properties, it has become common-level materials. It`s widely used in a variety of mechanical structures and spare parts. Compared to PA6, PA66 own the higher hardness, rigidity, better resistance to wear and heat deflection temperature. Temperature resistance from -40℃ to 110 ℃.
Advantages:
Disadvantages:
♦ High strength and stiffness
♦ High impact and notch impact strength
♦ High heat deflection temperature
♦ Good at dampening
♦ Good abrasion resistance
♦ Low coefficient of friction
♦ Good chemical stability against organic solvents and fuels
♦ Excellent electrical properties, ease of printing and dyeing
♦ Food safe, noise reduction
♦ Poor dimension stability, electrical and mechanical properties may become affected by absorbing moisture or water
♦ Poor acidproof ability, can`t dye with acid or touch overmuch acid
♦ Poor lightfastness, poor endurance in pollution
