The invention relates to a marine low-smoke halogen-free low-toxicity frame-retardant fire-resistant soft optical cable and a manufacturing method thereof, and belongs to the technical field of optical communication special optical cable manufacturing. The marine low-smoke halogen-free low-toxicity frame-retardant fire-resistant soft optical cable is a special fire-resistant optical cable for data communication, and is composed of ultra-low-loss low-temperature-resistant tightly-sleeved optical fiber units, a high-modulus aramid fiber and waterproof aramid fiber mixed reinforcing piece, a halogen-free low-smoke flame-retardant polyolefin oxygen-isolation layer inner protective sleeve, a fire-resistant white mica tape wrapping layer, a stainless steel wire woven wire layer and a crosslinked polyolefin outer protective sleeve. The ultra-low-loss low-temperature-resistant tightly-sleeved optical fiber units are twisted, high-modulus aramid fiber and waterproof aramid fiber are adopted for making the high-modulus aramid fiber and waterproof aramid fiber mixed reinforcing piece, the oxygen-isolation layer inner protective sleeve wraps the reinforcing piece in an extruded mode, the fire-resistant white mica tape wrapping layer wraps the oxygen-isolation layer inner protective sleeve, stainless steel wires are woven outside the fire-resistant white mica tape wrapping layer to form the stainless steel wire woven wire layer, and the crosslinked polyolefin outer protective sleeve wraps the fire-resistant white mica tape wrapping layer and the stainless steel wire woven wire layer in an extruded mode.

The invention discloses a preparing method of graphene luminous cutting-prevention flame-retardant firefighting gloves. The gloves are woven through one or more of aramid fiber 1414/graphene chinlon core-spun yarn, stainless steel wire/ aramid fiber 1414 coating yarn, luminous-green dacron DTY yarn, spandex-coated nylon dyed yarn and shirr; the woven gloves are impregnated through high-temperature-resistance and environment-friendly silica gel to obtain a finished product. The preparing technology is simple, the gloves can be produced on a large scale, and are high in cutting resistance, conductivity, flame retardance, static resistance, bacterial resistance, cutting resistance, fire resistance, skid resistance, and wearproof performance, and are comfortable and convenient to wear. The preparing method can be widely applied to special industries like equipment manufacturing and firefighting.

The invention provides a closed type heavy-load thin wall light-duty pulley device and belongs to the technical field of heavy industrial machinery. The device comprises an end cover, a wheel hub, two webs and a rope groove which are annular and are connected in sequence from inside to outside, and further comprises a shaft which is arranged inside an inner ring of the end cover, a bearing for supporting the shaft and an inner ring supporting sleeve for positioning the bearing. The two webs are located at the positions on the two side faces of the pulley device and are at the same radial position of the pulley device. The wheel hub and the end cover are fixed by a stainless steel wire rope; an outer ring of the end cover is connected with the wheel hub; a gap being not more than 0.1mm is formed between the inner ring of the end cover and the inner ring supporting sleeve. An inner cavity composed of the wheel hub, the end cover, the inner ring supporting sleeve and the shaft is fully filled with lubricating grease to form a closed structure. The closed type heavy-load thin wall light-duty pulley device is free of maintenance; the lubricating grease can be fully filled in one time and does not need to be replaced within 4-5 years; meanwhile, the pulley device which has lighter self weight, greater load and smaller wall thickness is effectively realized and the service life of the pulley device is greatly prolonged.

The invention relates to an environment-friendly water-soluble stainless steel wire drawing liquid. The environment-friendly water-soluble stainless steel wire drawing liquid comprises the following raw materials in parts by weight: 3-5 parts of water-soluble antirust agents, 10-20 parts of special esters, 3-5 parts of coupling agents, 3-5 parts of special amine, 20-30 parts of base oil, 10-20 parts of special surfactants and the balance of water. The environment-friendly stainless steel wire drawing liquid provided by the invention has excellent lubricating property and cleaning property dueto compounding of special esters and special surfactants, can effectively prevent fine scratches of a processing surface, can protect a die more effectively than a traditional water-soluble wire drawing liquid, and has an excellent use effect.
