U-pvc drainage plastic pipe plus casing, a protective measure by external damage is to prevent the pipeline roots. (PVC insulation sleeve is most afraid of destruction from the roots, because maintenance is very difficult).

Similarly, for plastic water supply pipes in the floor with an additional sleeve, take into account not only the construction or maintenance, more to protect the roots is not destroyed. As we all know, plastic water pipe, casing, not necessarily through the floor, but, on the floor height clear, the purpose of this is it.

CIP-Teflon (PTFE / PTFE / Teflon protection of cables and metal tube) Teflon / Teflon heat shrink tubing for extreme conditions.

Product Description:

CIP-Teflon by Teflon / Teflon (PTFE / PTFE / Teflon) is made to meet the requirements of the U.S. military standard SAE-AMS-DTL-23053/13 has excellent weatherability, abrasion resistance, cut resistance and other properties, all oil and chemical solvents corrosion resistance, long-term use in high temperature of 260 ℃. Applications requiring ultra-high temperature resistance, resistance to fluid corrosion and the need for high insulation and fire-retardant occasions on the welding point, line terminal and junction protection.

The following is an introduction Teflon insulation sleeve, first we have to understand that the Teflon insulation sleeve is a high temperature PTFE sleeve.

For this kind of material, a brief description. Teflon heat shrink tubing with a high temperature, corrosion resistance, high pressure, flame retardant, and long-term non-aging and other characteristics. Widely used in the aerospace, instrumentation, textile, chemical, food, medical, electronic and electrical appliances, post and telecommunications, petrochemicals, metallurgy and electronics, railway transport, electrical appliances, household appliances, high-rise buildings, lighting, special transformers, special cables, sensors , thermal components industry.

Feature

Contraction ratio of 1.7:1 or 4:1

High flame retardant, good toughness, excellent physical properties and chemical resistance

No chlorine compounds PCBS, PCPS polybrominated biphenyls PBBs the polybrominated oxidation biphenyls PBBOs, Polybrominated diphenyl ethers PBBEs, PBDEs, and other environmentally harmful substances, the European RoHS environmental directives and SONYSS00259 of standards in line with the requirements of environmental protection.

Polyurethane fiberglass casing, is compiled by the E-glass fiber casing pipe coated with polyurethane high temperature treatment from.

Has good dielectric properties, self-extinguishing and softness, and wait until the internal line cluster in H & N motor, household appliances, electric equipment, special lighting, television and electronic instruments are widely used in insulation protection.

PU polyurethane fiberglass casing is made of E-glass fiber sleeve yarn after high-speed knitting machine the fine woven billet tube coated with a specially formulated polyurethane resin and then the high-temperature vulcanizing stereotypes made. Because the casing often temperature can reach 155 degrees Celsius, the electrical properties is excellent and has good mechanical abrasion resistance and flexibility, it is widely used in the F-class motor insulation.

Fiberglass sleeving

Described below is based on glass fiber yarn woven fiberglass sleeving.

1 glass cloth, glass cloth produced in our country, is divided into two types of non-alkali and alkali abroad, the majority of non-alkali glass cloth. The glass cloth is mainly used for the production of electrical insulation laminates, printed circuit boards, a variety of vehicles, bodywork, tanks, boats, mold. Alkali glass cloth is mainly used for the production the coated packing cloth, as well as for corrosion-resistant applications. Determined by the characteristics of the fiber properties, Jingwei density, yarn structure and textured fabric. Jingwei density is determined by the yarn structure and textured. And density plus the yarn structure, it determines the physical properties of the fabric, such as the weight, thickness and rupture strength. There are five basic weave: plain weave, twill, satin, rib and seats pattern.

2, glass with glass band divided into sidebands have woven and non-woven the sidebands (burr band) mainly woven corrosion is plain. Glass with commonly used in the manufacture of high-strength, good dielectric properties of electrical equipment parts.

3, four by breaking a coarse warp and fine weft yarns satin or the long axis satin fabric to fabric unidirectional fabric. Which is characterized by high up in the warp main strength.

4, the three-dimensional fabric of the body fabric is in relatively flat fabric, its structural characteristics from the one-dimensional two-dimensional to three-dimensional, so in order to enhance the body of the composite material has good integrity and profiling, greatly improving the composite interlaminar shear strength and resistance to damage tolerance. It is developed with the special needs of the aerospace, aviation, weapons, ships and other departments, has expanded its application to the automotive, sports equipment, medical equipment, and other departments. There are five types: the three-dimensional fabric of the woven, knitted three-dimensional fabric, orthogonal, non-woven and non-orthogonal three-dimensional fabric, three-dimensional woven fabrics and other forms of three-dimensional fabric. Three-dimensional shape of the fabric massive, cylindrical, tubular, hollow frustum and variable thickness shaped cross section.

5, the shape of the the shaped fabric profiled fabric and it is necessary to enhance the shape of the article is very similar, must be dedicated loom weaving. The symmetrical shape shaped fabric: dome cone hat, dumbbell-shaped fabrics, etc., can also be made to the asymmetric shape of the box, hull.

6 slotted core fabric, the core fabric is parallel to the fabric consists of two layers, consisting of fabric with the longitudinal bars connected together, the shape of its cross-section may be triangular or rectangular.

7, glass fibers stitched fabric, also known as knitting mat or woven carpet It is different from ordinary fabrics, also felt different from the usual sense. The most typical of the stitchbonded fabric is a layer of warp yarns and a layer of weft yarn overlap, together into a fabric by stitching the warp and weft weaving. Sewn braid, the advantages are as follows: ① It can increase the limit of glass steel layer co-products of the anti-tensile strength under tension resistance to delamination strength, and flexural strength; ② The lighten the weight of the glass fiber reinforced plastic; ③ The surface smooth so that the surface of the FRP smooth; ④ simplify hand lay-up operations, and improve labor productivity. This reinforced materials FRP pultrusion and RTM instead of continuous strand mat, you can also replace the woven roving FRP pipe production centrifugation
