3Deng, synthetic resin powder is mixed and made into filtering material.Filtering accuracy can reach 5～100 μ, and the precision of this filtering material is by adding inorganic foaming agent and synthetic resin, and 250 ℃ ± 20 ℃ of sintering temperatures during sintering are controlled, so complex manufacturing, and product purity is not high.
The object of the present invention is to provide a kind of high efficient filter sound silencing element core and production technology thereof, this product cost is low, and is nontoxic, the purity height, and good filtration effect is difficult for fragmentation, acid and alkali-resistance, technical process is simple.
The objective of the invention is to realize by following means.
A kind of high efficient filter sound silencing element core and production technology thereof, it is characterized in that this high efficient filter sound silencing element core is that the employing ultra high molecular polyethylene is a filter medium, the production technology of this product is with the ultra high molecular polyethylene powder, adds in the mould of set different shape, puts into heating furnace and carries out sintering, temperature is in 150～300 ℃ of scopes, be 20～80 minutes heat time heating time, takes out, and cools off with filtered water, the demoulding promptly gets high efficient filter sound silencing element core.The mean molecule quantity of ultra high molecular polyethylene is 100～2,000,000, and powder size is 20～100 orders.The ultra high molecular polyethylene powder is a filter medium, and filtering accuracy is 0.3～100 μ, adds the NaCl powder, and granularity is 20～100 orders, and the weight quota proportioning is 1 part for the ultra high molecular polyethylene powder; The NaCl powder is 2 parts, and filtering accuracy is 100～150 μ.Can add versicolor pigment in the ultra high molecular polyethylene powder.Mould adopts stainless steel to make, and the demoulding can utilize the automatic demoulding method of expanding with heat and contract with cold, and also can adopt pressure demoulding method.A kind of purposes of high efficient filter sound silencing element core is used for the purified treatment of liquids and gases, it is characterized in that being used for the silencer element core.
A kind of high efficient filter sound silencing element core and production technology thereof are filter medium owing to adopt ultra high molecular polyethylene, and this toughness of products is good, acid and alkali-resistance, difficult broken, and it is good to filter sound-absorbing effect, and the cost of product is low.By granularity, sintering temperature and the time controlled filter precision of ultra high molecular polyethylene powder, technical process is simple, need not add inorganic foaming agent and synthetic resin, the purity height of product, nontoxic, no automatic pollution, the easily blowback use of can regenerating again.This product filtering accuracy is 0.3～150 μ m; porosity 48～54%; 0.03Pa falls in pressure; erasure effect, noise descend 30 decibels, can be widely used in electronics, pharmacy, food, chemical industry, cigarette, automobile making and application and the environmental protection each field of air cleaning and fluid purification; improve the quality of products; improve outmoded filtering technique, the noise reduction dedusting improves environment.
