Digestion furnace applications, the digestive tubes were placed in each hole in the digestive rack, and then placed in the digester, and immediately open the suction pump valve, so that the suction pump is in the suction state. When the power is turned on, during the initial stage of heating, attention must be paid to observation to prevent the sample from splashing due to abrupt boiling (the initial voltage is adjusted to 180-190V). After the foam is stopped, the voltage is adjusted to 220v, and after cooling for 100-105 min.
When using the semi-micro Kjeldahl method to determine the protein content of milk, a porous well-type electric heating furnace is used, and a suitable inexpensive catalyst is placed before digestion to digest the milk sample, which greatly improves the thermal effect of the digestion sample. At the same time, the digestion time has also been shortened a lot. Milk protein contains 7.1% (mass fraction) of lysine and 2.6% (mass fraction) of histidine. Nitrogen in these two amino acids is not digested completely in a short time, which often leads to low total nitrogen. Digestion furnace digestion time is too long will cause loss of ammonia. The method is used to determine the protein in milk, and the time for digesting one sample is 100-105 min, and the coefficient of variation is 0.62%. The results obtained by this method are accurate, accurate, stable, simple, fast and safe, and can meet the detection requirements of batch samples.
This kind of part is used in Plastic Injection Mould and as one of the components. Our company can finish the whole process from the making of Mould Parts and the complete mold to the producing of Plastic Injection Parts , including the Plastic Injection Molding design.
Injection molding is a process in which custom molded component manufacturers heat a polymer until it reaches a highly plastic state and forces it to flow under high pressure into a mold`s cavity to solidify. Manufacturers then remove the molded part, or molding, from the cavity. The process produces discrete components that are almost always net shape, reducing the need for surface finishing. A mold may contain more than one cavity, allowing Custom Injection Molding companies to produce multiple moldings each cycle. The production cycle time ranges between 10 and 30 seconds. Cycles of 60 seconds or longer are also common.
