wherein: nylon 12 chemistry are commonly called as nylon 12, and PA12, Chinese claim polylauryllactam again.
The characteristic of nylon 12 is following:
A: nylon 12 is linear from butadiene, hypocrystalline-crystallographic thermoplastic material.Its characteristic is similar with nylon 11, but crystal structure is different, and relative density is little, and only 1.02, be minimum in the nylon series;
B: water absorption rate is low, and dimensional stability is good; Lower temperature resistance is good, can reach-70 ℃;
C: fusing point is low, and processing and forming is easy, forming temperature wider range; Flexibility, chemical stability, oil resistance, resistance to wear are all better, and belong to self-extinguishing;
D: long-term serviceability temperature is 80 ℃ (after heat treatment can reach 90 ℃), can be in oil in 100 ℃ of following long-term works, but the long-term work temperature is 110 ℃ in the inert gas;
E: method is processed into monofilament, film, plate, rod, section bar can to adopt injection moulding, extrude etc., and powder can adopt methods processing such as thermopnore infusion process, electrostatic spraying method, rotational forming, especially suits to apply and spraying in the metal surface;
F: nylon 12 be good electrical insulators and the same with other polyamide can be because of the moisture effect insulation property, it has good impact resistance chemical machine stability;
G: the viscosity of nylon 12 depends primarily on humidity, temperature and storage time;
H: it mobile fine, shrinkage is between 0.5% to 2%, and this depends primarily on description of materials, wall thickness and other process conditions;
I: nylon 12 has many improving the breed aspect plasticizing characteristic and the enhanced characteristic, compares with PA6 and PA66, and these materials have lower fusing point and density, have very high regain, 12 pairs of acid with strong oxidizing property passivities of nylon ability.
Because the technique scheme utilization, the utility model compared with prior art has advantage:
The ant-proof mouse-proof layer that
the utility model adopts the polyvinyl chloride separator to add nylon 12 adds the polyvinyl chloride sacrificial layer structure and reaches the ant-proof mouse-proof effect; Test by colony's method through GB/T 2951.38 " the termite-proof test method of electric wire "; The indentation of tangible termite moth erosion is not seen on nylon sheath surface, reaches 1 grade of moth erosion grade; Environmental-protecting performance meets the RoSH of European Union command request.
