Abstract
The invention relates to an exhaust passage and a production method thereof. the middle of the exhaust passage body is provided with gridding cloth serving as a framework; a cement molding material is coated on the outside of the framework; and the cement molding material comprises the following raw material components in part by weight: 25 to 35 parts of cement, 25 to 35 parts of yellow sand, 15 to 25 parts of water and 1 to 2 parts of glue water. During production, the raw materials are reasonably proportioned and stirred, and then are pressed to form the exhaust passage by a mold. The exhaust passage has strong acid and alkali resistance; the service life of the exhaust passage can be prolonged; and social resources are saved.
Description
Technical field
The present invention relates to a kind of exhaust duct and production method thereof.
Background technology
Exhaust duct in the market is of all kinds, is various in style, and is different, but these exhaust ducts because the moulding material difference, the acid-proof alkaline that has is too poor, runs into corrosion soon behind acidity, the basic matterial, becomes soft, loses due effect.
Summary of the invention
For solving above-mentioned the deficiencies in the prior art, the invention discloses a kind of exhaust duct and production method thereof.Be provided with grid cloth as skeleton in the middle of this exhaust way body, skeleton is coated with the cement moulding material.This exhaust duct has very strong acid-fast alkali-proof performance, long service life.
The present invention adopts following technical scheme for achieving the above object:
A kind of exhaust duct is characterized in that: be provided with grid cloth as skeleton in the middle of the described exhaust way body, skeleton is coated with following cement moulding material; The weight portion of the raw material components of cement moulding material is:
Cement 25-35 part
Yellow sand 25-35 part
Water 15-25 part
Glue 1-2 part.
The production method of described exhaust duct is characterized in that: may further comprise the steps:
(1) presses the raw material of formula rate weighing cement moulding material;
(2) raw material with load weighted cement moulding material fully mixes;
(3) raw material of the cement moulding material that mixes is filled a part earlier in the mould of exhaust duct, pave raw material according to the thickness that reality requires;
(4) lay one deck grid cloth on the raw material top layer that step (3) is paved;
(5) on grid cloth, lay the raw material of cement moulding material again, pave the surface, pave raw material according to the thickness that reality requires;
(6) can obtain product to the mould extrusion forming.
Advantage of the present invention:
Drain of the present invention is owing to have additional grid cloth in the road body, so the acid resistance of drain and alkali resistance improve greatly, prolonged the application life of drain, reduced the waste of social resources.
The specific embodiment
A kind of exhaust duct is provided with grid cloth as skeleton in the middle of this exhaust way body, and skeleton is coated with following cement moulding material; The weight portion of the raw material components of cement moulding material is:
Cement 25-35 part
Yellow sand 25-35 part
Water 15-25 part
Glue 1-2 part.
The production method of exhaust duct specifically may further comprise the steps:
(1) presses the raw material of formula rate weighing cement moulding material;
(2) raw material with load weighted cement moulding material fully mixes;
(3) raw material of the cement moulding material that mixes is filled a part earlier in the mould of exhaust duct, pave raw material according to the thickness that reality requires;
(4) lay one deck grid cloth on the raw material top layer that step (3) is paved;
(5) on grid cloth, lay the raw material of cement moulding material again, pave the surface, pave raw material according to the thickness that reality requires;
(6) can obtain product to the mould press molding.
