Next shot blasting process will replace the casting process

Many castings are required to carry out blasting process, but with the casting process of continuous improvement, a new casting processing methods - blasting process is rapidly emerging, and replace the blasting process trend.
Shot blasting machine blasting process technology and the fundamental difference is that the projectile, rather than jet ejections is not sand, but the steel shot. Shot blasting is much larger than the diameter diameter. His theory is based on the specific requirements of the different size high speed steel shot hitting the plate surface, the impact force of a huge steel shot rapid erosion of the surface of the sheet formed a strong sense of body surface. With this method of processing out of the casting products, not only stable quality, beautiful appearance is not blind, and processing speed, and low cost. According to experts speculate that future technology will throw sand blasting process replaced.This utility model relates to a one-time immobilized enzyme column organophosphorus pesticides speed Molybdenum tube instrument, which consists of color reagent and buffer reservoir and infusion unit test enzyme column unit, delay tube unit, a detection unit and and the result output from the control unit is configured to, infusion unit, the test enzyme column element, delay tube unit, the detection unit back and forth between the soft flexible hose connected to corrosion. As the utility model uses the immobilized enzyme column, and its advantages are: high sensitivity and stability; enzyme column rapid loading and unloading technology can detect the enzyme than the liquid speed; reference enzyme inhibition with pre-column means can be more available Tachometer more effectively reduce the false positive rate.
[574-0084-0007] braided stainless steel mesh water pipe
[Abstract] This utility model designed a stainless steel wire braided water pipes, the water pipes including stainless steel wire braided hose mesh lined aqueduct, and one end of the tube outside the ratchet has stepped over, one with stairs The interface is compatible with nut and end of the compression sleeve bead, bead has a threaded bushing pressed to take over between the steps and the ratchet has a match with bead thread external thread. The utility model mesh weave water pipe, using a receiver with an external thread, a bead with a mating threaded clamping sleeve, the screen aqueduct firmly fastened to the takeover, and its structure is more compact, and can greatly improve the tensile strength, by the Chinese Ministry of Light Industry Standard QB/T1334-98 determined by the method specified, the internal pressure up to 20 kg / cm 2, much higher than the existing technology It can be widely used in a variety of civil and industrial water systems.
