Problems solved by technology

For good flame retardancy, the amount of plasticizer needs to be reduced, which leads to rough appearance of the cable
In the low-smoke non-halogenated polyolefin cables that meet the VW-1 flame retardant test requirements of the UL standard, the proportion of flame retardants is even higher than that of ordinary low-smoke non-halogenated polyolefin cables, which leads to the appearance of the cables Poor brightness, easy to be scratched during processing

Embodiment 1

[0030] This preferred embodiment provides an oil filter for low-smoke, halogen-free cable production. like figure 1 As shown, the oil filter at least includes a hollow box 1 arranged on a bracket 8, and an oiling device 2, a water washing device 3 and a wiping device 4 are sequentially arranged in the box 1, and the box 1 is provided with an oiling device 6 and Water injection device 7. Wherein, the oiling device 2 , the water washing device 3 and the wiping device 4 are respectively provided with through holes for receiving the low-smoke halogen-free cables 5 to pass through.

[0031] The oiling device 2 is made of a sponge, and is used to coat the outer surface of the low-smoke, zero-halogen cable 5 with silicone oil; the washing device 3 is made of a sponge, and is used to wash off the outer surface of the low-smoke, zero-halogen cable 5 The excess silicone oil on the surface; the wiping device 4 is made of cotton cloth, and is used to remove excess silicone oil on the ou...

Embodiment 2

[0044] This preferred embodiment provides an oil filter for low-smoke, halogen-free cable production, the structure of which is basically the same as that of the preferred embodiment 1. The oiler at least includes a hollow box, and the box is provided with an oiling device and a wiping device in turn, and the oiling device and the wiping device are respectively provided with through holes for accommodating low-smoke halogen-free cables; wherein, the oiling device The device is used to coat the outer surface of the low-smoke zero-halogen cable with silicone oil; the wiping device is used to remove excess silicone oil on the outer surface of the low-smoke zero-halogen cable.

[0045] The difference is that as long as the amount of silicone oil in the oiling device can be strictly controlled, the thickness of the silicone oil coated on the surface of the low-smoke and halogen-free cable will be ideal after passing through the wiping device, and the low-smoke and zero-halogen cable...

Abstract

The invention discloses an oil immersing device for production of low-smoke halogen-free cables and a method for producing low-smoke halogen-free cables, belongs to the field of low-smoke halogen-free cable production devices and methods and is designed to solve the problems of serious scratching of prior cable surfaces and the like. The oil immersing device at least comprises a hollow case, an oil coating unit and a wiping unit are arranged in the case successively, and a through hole for the low-smoke halogen-free cable to pass through is formed in the oil coating unit and the wiping unit respectively. The oil coating unit is used for coating organic silicone oil on the outer surface of the low-smoke halogen-free cable. The wiping unit is used for removing redundant organic silicone oil on the outer surface of the low-smoke halogen-free cable. By means of the oil immersing device and the production method, the outer surface of the low-smoke halogen-free cable can be protected against being scratched in subsequent processes.

Description

technical field [0001] The invention relates to an oiler for producing low-smoke, halogen-free cables and a production method for low-smoke, halogen-free cables based on the oiler. Background technique [0002] Low-smoke and halogen-free cables have very little smoke and no corrosive gas escape when burning. They are widely used in nuclear power plants, subway stations, telephone exchanges and computer control centers, high-rise buildings, hotels, radio and television stations, important military facilities, and oil platforms. Various crowded places with low air density. [0003] Flame retardants and plasticizers are two important ingredients in low-smoke, halogen-free materials. For good flame retardancy, the plasticizer content needs to be reduced, which leads to rough appearance of the cable. In the low-smoke non-halogenated polyolefin cables that meet the VW-1 flame retardant test requirements of the UL standard, the proportion of flame retardants is even higher than t...
