According to the manufacturing technique of the elastomer composite self-floating rubber tube, a tube blank is manufactured firstly, and then the elastomer composite self-floating rubber tube is manufactured with the spray-molding technique; the molding of inner glue is replaced with the molding of the single-face rubber lining canvas layer, and the vulcanizing time of the tube blank is shortened due to the elimination of the inner glue; the interior of the tube is molded in a composite mode with the spray-molding technique, a composite elastomer is made of polyurethane elastomer spraying materials or polyurea elastomer spraying materials, and therefore wear resistance is excellent, the service life of a mud discharging rubber tube is prolonged after the inner glue is replaced, and good economic benefit is achieved; the adoption of the middle canvas layer improves the bonding strength between the elastomer and the cord fabric; due to the fact that specialized supports are designed and used in the technique, the deformation of the tube body is avoided.
Description
Technical field
The invention belongs to machinery manufacturing technology field, be specifically related to a kind of from floating sebific duct and production technology thereof.
Background technique
Existing dredger generally adopts natural rubber to make hose lining from floating sebific duct and since the dredging soil property by mud class, fine silt to the medium coarse sand transition, simultaneously because working pressure is increasing.Traditional floating certainly sebific duct hose lining serious wear, obviously shorten working life, is difficult to adapt to current construction requirement.Often influence dredging efficiency because damaging from floating sebific duct, cause manufacturing efficiency to reduce, cost of production strengthens.
Existing sludge suction rubber pipe production technology at first forms hose lining, and then the short cover of assembling flange steel and hangings lay, vulcanizes at last, and cure time is longer, in manufacture process, also has problems such as body is yielding.
For increasing the wear-resisting property of sebific duct, can use high-abrasive material to substitute hose lining, but the hangings lay adhesion strength that conventional high-abrasive material and terylene or polyamide fibre are formed is very poor, and for the software sebific duct, does not also have ripe wearing layer moulding process at present.
Summary of the invention
For solving the problems of the technologies described above, the invention provides a kind of elastomer composite from floating sebific duct and production technology thereof.
Of the present invention from floating sebific duct mainly by outer protective layer, tighten steel wire, hangings lay, outer layer glue, floating layer, the short cover of steel and form; solving the technological scheme that its problem adopts is at floating certainly sebific duct hangings lay internal surface the mesosphere to be set; the mesosphere is canvas layer; internal surface arranges composite bed in the mesosphere, and composite bed is polyurethane material or polyureas.Of the present invention compound identical with existing certainly floating sebific duct internal diameter size from floating sebific duct internal diameter size.
Elastomer composite of the present invention may further comprise the steps from floating sebific duct production technology:
(1) the pipe embryo is made: according to the composite elastic body thickness, design also determines to make the shaping die external diameter of using from floating sebific duct; Fastening flange steel weak point overlaps and locatees according to designing requirement on floating certainly sebific duct shaping die, the middle canvas layer of winding single face rubber between the short cover of two flange steel, and the one side of rubber is outwardly; Put intersection winding line with rubber nylon or terylene hangings lay at middle canvas layer and steel weak point, two ends adopt steel wire to tighten, the moulding outer layer glue, it is floating certainly that the sebific duct inner tube is body formed finishes winding water cloth and rope and sulfuration, after the cooling, brush tackiness agent in appearance, and the floating layer of moulding, at floating layer outside moulding outer protective layer, winding water cloth, rope and cryogenic vulcanization then, the floating certainly sebific duct pipe embryo demoulding that vulcanizates is standby;
(2) spray mo(u)lding: will go to embroider from the short cover of floating sebific duct pipe embryo two end flange steel internal surface and handle totally, be fixed on the support then, to prop up and be placed on the spraying swivel mount, start spraying machine, carry out polyureas or polyurethane coating while rotating in floating certainly sebific duct inwall, the design thickness that reaches composite bed namely gets elastomer composite from floating sebific duct.
Support of the present invention is made up of 2 or a plurality of circular frame, and the fixed arm of 3 adjustable in length evenly is set in each circular frame, and fixed arm is connected by bolt with circular frame, and adjacent two circular frames are connected by metal bar.
Fixed arm in the framework pipe embryo is overlapped with the center of circle of circular frame, thereby guaranteed that spraying or centrifugal process middle tube body can not be out of shape, and the thickness of composite bed is even by regulating.
Good effect of the present invention is:
1, removes the moulding of hose lining in the technology, change the moulding of single face line with rubber canvas layer into, owing to remove hose lining, shorten the cure time from floating sebific duct pipe embryo;
2, the inner mode of spray mo(u)lding that adopts is carried out compound molding, and composite elastic body is polyurethane or SPUA sprayed on material, and abrasion resistance properties is good, has prolonged the working life of spoil disposal sebific duct behind the alternative hose lining, has good economic benefit;
3, adopt middle canvas layer to improve the bonding strength of elastomer and hangings lay on the structure;
4, design and use special stand overcome the body distortion in this technology.
