Accompanying drawing explanation
Fig. 1 is the structural representation of RPM of the present invention.
Detailed description of the invention
The implementation of the present invention is described in detail below in conjunction with embodiment.
The nano modification RPM of the present invention is made up of 7 Rotating fields, respectively inner liner 1, interior circumferential winding layer
2, interior axial direction fibre layer 3, burning into sand layer 4 (i.e. nano modification resin sand pulp layer), outer axial fibrous layer 5, outer circumferential winding layer 6, outer
Protective layer 7 forms.
Wherein, inner liner 1: the effect of this layer is to ensure that RPM under pressure can be the most defeated
Send material, make the work that product is steady in a long-term.This layer is by the surface felt of high resin content (resin content is at 70-92%) and chopped
Felt forms, and has the features such as wear-resisting, corrosion-resistant, antiseep.
Interior circumferential winding layer 2 and outer circumferential winding layer 6: this two-layer is the bearing bed of RPM, which ensures pipe
Hoop tensile strength, hoop bending strength and rigidity.This two-layer, by the glass fibre continuous winding yarn of high intensity, uses hoop
The mode being wound around processes, and its resin content is between 25-35% weight.
Interior axial direction fibre layer 3 and outer axial fibrous layer 5: this two-layer is the bearing bed of RPM, which ensures pipe
Axial tensile strength and axial rigidity.This two-layer, by chopped axial direction fibre or axial direction fibre fabric, uses the side that hoop is wound around
Formula processes, and its resin content is between 45-65% weight.
Burning into sand layer 4: this layer is the bearing bed of RPM, is arranged near the neutral line of pipe, and Main Function provides
The axial compression strength of pipe and toughness.It constitutes sandwich sandwich structure with the glass layer of high intensity, and riser hoop is curved
Stiffness, increases tubular loading ability.This layer is by bi-component nano material (the surface treated nanometer titanium dioxide of 1-8% weight
Silicon and nm-class active calcium carbonate mixture) dispersion mixing in resin, obtain mixing nano-material modified resin matrix, then should
Resin matrix and quartz sand carry out action of forced stirring and mix, and its resin content is between 15-18% weight.
External protection 7: this layer is the external protection coating of RPM, has good corrosion-resistant, abrasion resistance properties.Should
Layer is made up of the chopped strand of virgin resin and high intensity, and its resin content is between 70-100% weight.
By laboratory research test display, use high intensity and the resin of high tenacity, such as epoxy polyamide solidification tree
Fat or vinyl ester resins, can meet in the case of the resin content of 15-18% general quartz sand graduation (as 20 mesh-
40 mesh accountings 100%) resin mortar compressive strength higher than 75Mpa, but the problem being primarily present is that above-mentioned resin price is high,
And its be high corrosion resistant or other particular/special requirements under conditions of could apply.
By the quartz sand of variable grain diameter being carried out the compounding of different proportion, illustrate that the level pairing compression of quartz sand is strong
The impact of degree is relatively big, and the intensity of the quartz sand resin mortar of the strength ratio poor grain size distribution of the quartz sand resin mortar of good grating is high
Going out more than 30%, result of the test display uses the compressive strength under following grain composition can meet requirement:
| Particle size range | Quality accounting % |
| 10 mesh-20 mesh | 45% |
| 30 mesh-60 mesh | 15% |
| 70 mesh-80 mesh | 15% |
| ＞ 90 mesh | 25% |
| Add up to | 100% |
But the grating of quartz sand must size particles be respectively configured and it is necessary to there is part median particle diameter all to take
Disappear.And quartz sand supplier is unstable to the mixture of quartz sand, it is easily to occur that particle diameter separates in transport in producing.By stripping
Burning into sand layer from section of tubing finds its grain composition grating the most set in advance, and material mixing is the most uneven simultaneously, causes
Push pipe intensity dispersion is big.After testing, the product that same batch of material is produced, the peak of its compressive strength and minimum can phases
Differ from more than one times.
The following is different resins mixture and quartz sand mixing after formed burning into sand layer push pipe compressive strength contrast test:
