Abstract

The utility model discloses a filter press blanket comprising an upper layer of degreasing bleached cotton layer, a lower layer of degreasing bleached cotton layer and a middle pure cotton non-woven fabrics filter element layer. The upper layer of degreasing bleached cotton layer is bonded with the middle pure cotton non-woven fabrics filter element layer by a bonding layer; the lower layer of degreasing bleached cotton layer is bonded with the middle pure cotton non-woven fabrics filter element layer by a bonding layer; the bonding layer is made into one layer by mixing refined cotton and adhesive. As the bonding layer adopts the structure that the refined cotton and the adhesive are mixed and made into one layer, not only the basic bonding function is realized, but also can the strength of the filter cloth be ensured; as the bonding layer with such a structure also has good flatness and property of non-dissolved in acetone, the invention aims of improving the filtering capabilities and the filtering accuracy are achieved by a simple structure.

Description

Canvas press cloth

Affiliated technical field

The utility model relates to a kind of filter cloth, particularly Zhuan Yong canvas press cloth.

Background technology

At present, known canvas press cloth generally adopts the single or multiple lift structure of cotton or fiber cloth, typical multilayer canvas press cloth is composited by the degreasing bleached cotton cloth layer on upper strata, the degreasing bleached cotton cloth layer and the middle pure cotton non-woven fabrics filter core layer of lower floor, even the canvas press cloth of this sandwich construction, still have that the filtering ability is weak, low, the flimsy defective of intensity, and filtering accuracy can not reach high requirement.

Summary of the invention

The purpose of this utility model be to provide a kind of simple in structure, the filtering ability is strong, filtering accuracy is high, intensity is high, non-damageable again canvas press cloth.

The technical scheme that its technical problem that solves the utility model adopts is: it comprises the degreasing bleached cotton cloth layer on upper strata, the degreasing bleached cotton cloth layer and the middle pure cotton non-woven fabrics filter core layer of lower floor, the degreasing bleached cotton cloth layer on upper strata is by tack coat and middle pure cotton non-woven fabrics filter core layer bonding, the degreasing bleached cotton cloth layer of lower floor is by tack coat and middle pure cotton non-woven fabrics filter core layer bonding, and described tack coat is mixed and made into one deck by purified cotton, adhesive.Tack coat adopts purified cotton, adhesive to be mixed and made into the structure of one deck, not only realized basic attachment function, guarantee the intensity of filter cloth, also since the tack coat of this structure have flatness good, be not dissolved in the characteristic of acetone again, realized improving the goal of the invention of filtering ability and filtering accuracy with simple structure.

Though the selection of single basis weight of fabrics numerical value is those skilled in the art's a general knowledge, but, for to the utility model ad hoc structure and consideration careless, that the secondary filter material combines, comprehensive definite rational basis weight of fabrics numerical value, to pursue best filtration result and filtering accuracy, remain the technology contents that those skilled in the art need creative work to realize.The utility model determine the specification of upper strata degreasing bleached cotton cloth layer be 140 ± 20 the gram/square metre, the specification of middle pure cotton non-woven fabrics filter core layer be 130 ± 20 grams/square metre, the specification of lower floor's degreasing bleached cotton cloth layer be 185 ± 20 the gram/square metre, can realize the foregoing invention purpose.

Furthermore, can determine specifically that the yarn count of upper strata degreasing bleached cotton cloth layer is 10S * 10S, the longitude and latitude number is 30 * 30 pieces/square inch, and the yarn count of lower floor's degreasing bleached cotton cloth layer is 21S * 10S, and the longitude and latitude number is 64 * 50 pieces/square inch.

The beneficial effects of the utility model are, and are simple in structure, the filtering ability is strong, filtering accuracy is high, intensity is high, and is not fragile again.

Description of drawings

Below in conjunction with drawings and Examples the utility model is further specified.

Fig. 1 is the structural representation of the utility model embodiment.

1. upper strata degreasing bleached cotton cloth layers among the figure, 2. lower floor's degreasing bleached cotton cloth layer, 3. tack coat, 4. tack coat, 5. centre pure cotton non-woven fabrics filter core layer.

The specific embodiment

The utility model comprises the degreasing bleached cotton cloth layer on upper strata, the degreasing bleached cotton cloth layer and the middle pure cotton non-woven fabrics filter core layer of lower floor, the degreasing bleached cotton cloth layer on upper strata is by tack coat and middle pure cotton non-woven fabrics filter core layer bonding, the degreasing bleached cotton cloth layer of lower floor is by tack coat and middle pure cotton non-woven fabrics filter core layer bonding, and described tack coat is mixed and made into one deck by purified cotton, adhesive.The specification of upper strata degreasing bleached cotton cloth layer be 140 ± 20 the gram/square metre, yarn count is 10S * 10S, the longitude and latitude number is 30 * 30 pieces/square inch; Lower floor degreasing bleached cotton cloth layer adopts on 2 the twill weave under 2, its specification be 185 ± 20 grams/square metre, yarn count is 21S * 10S, the longitude and latitude number is 64 * 50 pieces/square inch; Middle pure cotton non-woven fabrics filter core layer adopts medical absorbent cotton more than three grades, form by shredding-one-tenths net-soaking paste-oven dry, its specification be 130 ± 20 restrain/square metre.
