Description
Technical field
The present invention relates to a kind of septic tank manufacturing approach of composite molding, belong to glass fiber reinforced plastic pipeline manufacturing technology field, specifically a kind of technology that adopts fiberglass reinforced plastics to make septic tank.
Background technology
Septic tank is a kind of principle of utilizing deposition and anaerobic fermentation, to remove the organic transitional life processing structures of suspension in the sanitary sewage.The tank body of existing large-scale anaerobic digestor is mainly reinforced concrete structure, steel construction and Tang's porcelain structure, but Reinforced Concrete Materials is deposited unfavorable factor and is: cement structures does not possess rotproofness, is used for sewage treatment project, and maintenance cost is bigger; Cement surface is rough, not only causes the fluid resistance in the use big, and frictional resistance is also bigger in the work progress; High, construction complicacy that the digester building technology of steel and Tang's porcelain structure requires, and can't avoid because the underground water source that seepage is brought pollutes, and near the soft settlement of foundation problem that causes of the soil property seepage pipeline.It is a kind of novel flexible nonmetallic composite pipeline that occurs the seventies in 20th century that glass fibre strengthens solid thermal resin burning into sand pipe; Have characteristics such as in light weight, corrosion-resistant, that the inwall frictional resistance is little, the life-span is long; But it is constantly perfect that the technological water article of RPM also need; Along with the large-scale popularization of RPM, the simple glass steel matter of use also shows following unfavorable factor: one of which: add on the burning into sand process using or under add, layer of sand density is lower: its two: be to increase glass reinforced plastic pipe intensity; The general way that increases the internal and external layers of glass fiber that adopts causes fiberglass push pipe cost high like this; Its three, have styrene volatilization in the production process, cause production environment poor.
Therefore, along with the development of modern science and technology, novel material industry develop rapidly demands working out wide market of a adaptation and the material with development prospect urgently.
Summary of the invention
The present invention is intended to propose a kind of technology that adopts fiberglass reinforced plastics to make septic tank, and its purpose is: provide that a kind of production cost is low, the life-span long, in light weight, little composite molding glass fiber reinforced plastic pipeline and the production technology thereof of conveying liquid resistance.
Be the realization above-mentioned purpose, a kind of technology that adopts fiberglass reinforced plastics to make septic tank according to the invention, its production procedure is as follows:
One, takes by weighing raw material: take by weighing unsaturated polyester resin 42%, curing agent 0.7～1%, promoter 0.7～1%, glass cloth 7%, short felt (EMC450-1270) 7～7.3%, surperficial felt 4～4.3%, grid cloth 3%, glass fiber direct roving 23%, the glass injection yarn 12% cut by weight percentage;
Two, raw material processing: unsaturated polyester resin, curing agent, promoter in the above-mentioned substance are processed pulverized particles, and heating and melting mixes to resin compound in the pasty state then;
Three, main body moulding: 1. mould is prepared: get production mould, its oral area is placed on downwards on the things posited, in the waxing of the mould outside; 2. make lining: system lining in the mould outside; Sticking glass fabric is got above-mentioned paste resin mixture and outside waterproof cloth, is in layer evenly smeared, and whenever smears one deck and pastes layer of glass cloth on its surface; The every layer thickness of smear layer is 2～4cm, smears 3 layers at least; After treating that pastel solidifies, from the openend one side demoulding of mould; 3. structure is strengthened: carry out patrix again on the mould that glass fabric and resin are processed and wax; Paste again this time to paste and get the paste resin mixture and outside glass fabric, in layer evenly smear; Whenever smear one deck and twine layer of glass cloth on its surface, smearing every layer thickness is 2～4cm, smears three layers at least; Be used to improve tube wall axial strength and hoop, comprise hot strength, bending strength and impact strength; Replenish the gap on surface, treat that surface treatment end, pastel solidify after, from the openend one side demoulding of mould;
Four, middle locellus, end socket and installation check well head form septic tank of the present invention.
Said unsaturated polyester resin model is 196DC; Curing agent is a MEK; Promoter is accelerator M;
Describedly in making the lining step, successively twine three layers by paste resin mixture and glass fabric, wherein ground floor is a meter font winding, and the second layer is 45 ° of windings of pipeline, the 3rd layer of 135 ° of winding that is pipeline;
Describedly in structure is strengthened step, successively twine three layers by paste resin mixture and glass fabric, wherein ground floor is a meter font winding, and the second layer is 45 ° of windings of pipeline, the 3rd layer of 135 ° of winding that is pipeline; It is used for pumped (conveying) medium and anticorrosion and antiseep, improves tube wall axial strength and hoop, comprises hot strength, bending strength and impact strength;
Said glass fabric is: glass cloth 7%, the short felt (EMC450-1270) 7～7.3%, surperficial felt 4～4.3%, grid cloth 3%, glass fiber direct roving 23%, glass cut spray yarn 12%, with above-mentioned glass fabric uniform winding on mould.
A kind of technology that adopts fiberglass reinforced plastics to make septic tank according to the invention, its beneficial effect is: the septic tank that this glass fiber reinforced plastic pipeline is processed, satisfy the technological requirement that anaerobic digestor seals, heat insulating ability is high; Remove the corrosion resistance that the original material unsaturated polyester resin of reservation has, resistance to ag(e)ing, insulating properties etc. are beyond the characteristic; The glass fibre of resin being made matrix successively is wound on the lining made from three kinds of different modes by technological requirement, and its structural pipe wall is rationally advanced, gives full play to the effect of material; Under the situation of not using quartz sand, satisfy working strength, improve stiffness, guarantee that stability and the reliability of product, presentation quality are good; Reduce production costs; Simplify production technology, reduce the production difficulty, improve productivity effect; Use composite molding technique of the present invention, the designability of product is strong, the goods good combination property.
