According to the physical and electrical properties of optical cables, the laying of optical cables must meet certain requirements. In addition, the laying of optical cables in different environments also have their own requirements.

The laying of optical cables shall strictly comply with the following requirements:

(1) Length and integrity: The length of each cable should be controlled within 800m, and there is no relay in the middle.

(2) Minimum installation bending radius of optical cable: under static load, the minimum bending radius of optical cable is 10 times than the diameter of optical cable; under load conditions during wiring operation, such as pulling the optical cable out of the pipe, the minimum bending radius is 20 times than the diameter of optical cable; the minimum installation bending radius of four-core optical cable must be greater than 2in (5.08 cm). 

(3) Installation stress: The maximum installation stress applied to 4/6 core cable shall not exceed 100lbf (45kgf); when multiple 4/6 core cables are installed at the same time, the maximum installation stress per cable shall be reduced by 20%. For example, for 4x4 core cable, the maximum installation stress shall be 320lbf (144kgf).

Explanation: It is required that the traction force of the cable should not exceed 80% of the allowable tension of the cable, and the maximum instantaneous traction force should not exceed the allowable tension of the cable. The main traction force should be applied to the strengthened components of the cable, and the fiber can not bear the tension directly.

(4) Installation pulling force of optical fiber jumper: the maximum pulling force of single-core soft wire is 27 LBF (12.15 kgf), and the maximum pulling force of double-core soft wire is 550 LBF (22.5 kgf), and the distance of interconnection equipment should not exceed 100 ft (30 m).

(5) Judging the A.B end of optical cable: Before construction, we must first judge and determine the A.B end of optical cable. A-terminal should be oriented towards network hub
direction, while the B-terminal should be oriented to the user's side. The end of the laying cable should be in the same direction, and it must not be mistaken.

(6) No matter laying optical cables in buildings or between buildings, separate pipe holes should be occupied. If the original pipe and copper cable are used together, the plastic sub-pipe should be put through the hole. The inner diameter of the plastic sub-pipe should be 1.5 times than the outer diameter of the optical cable. The optical cable should be laid in the plastic sub-pipe, and the same sub-pipe should not be used with the copper cable. When laying optical cables are in parallel with other weak current systems in buildings, they should be laid separately and fixed, and the minimum net distance between the cables should meet the design requirements.

Liquid paraffin alias: white oil, paraffinoil, white oil, paraffinoil. Mineral oil foreign name :liquidparaffin. Liquid paraffin is a colorless and tasteless mixture obtained from the fractionation of crude oil. It can be divided into light mineral oil and general mineral oil, and the weight of light mineral oil and viscosity is lower. KING HONOR INTERNATIONAL LTD., a wholesale paraffin wax supplier, produces high quality liquid paraffin.

The character of liquid paraffin is colorless transparent oil-like liquid, no smell and no taste at room temperature, slightly smell of oil after heating. Density density 0.86-0.905(25) insoluble in water, glycerin and cold ethanol. It is soluble in benzene, ether, chloroform, carbon disulfide, hot ethanol. Mixed with most fats except castor oil, camphor, menthol, and most natural or artificial musk can be dissolved.

The main component is c16-c20 n-alkanes.

Applications: as a base for ointments, liniments, and cosmetics.

(1) as a result of mineral oil's low sensitivity and good closure, there is a barrier skin moisture evaporation. so it is often used as smooth moisturizer in baby oil, emulsion or cream medium skin care products.

(2) because of its good oil-soluble properties, it is also used as a makeup remover in makeup remover oil or makeup remover cream.

(3) because it is not digested in the intestine and absorption is minimal, the intestinal wall and feces play a role in lubrication, and can prevent the absorption of water in the intestine, softening stool, making it easy to discharge, often used as a laxative. [orally] take 15~30ml each time before going to bed. Liquid paraffin is divided into crude paraffin oil and refined paraffin oil according to its purity. Crude paraffin oil is considered as "carcinogenic substance" in medicine, and the "poisonous rice" which caused a sensation in the whole country was adulterated with crude paraffin oil, namely industrial paraffin oil. As the filling material, it is used for repairing saddle nose and augmentation nose. In the 1920s, liquid paraffin was widely used as a filler for decades until it was widely reported that the material was prone to paraffin tumors. Liquid paraffin is also used in the disinfection of medical equipment and anti-embroidery, but the specific effect is mixed.

KING HONOR INTERNATIONAL LTD. is a famous wholesale paraffin wax supplier in China, which provides high quality paraffin wax supply service for customers.

Microcrystalline wax is a kind of refined synthetic wax with similar microcrystalline properties, which has the characteristics of good luster, high melting point and light color. Microcrystalline wax is as white as jade, and can bring extremely beneficial impact on the production of light - colored products. In addition to normal paraffins and isomeric paraffins, the wax also contains many saturated hydrocarbons with long branched chains and rings. As a result, the melting point, molecular weight and viscosity of microcrystalline wax are higher than that of petroleum wax, and its brittleness is lower and it is not easy to break.

Microcrystalline wax is mainly composed of c30-50 cycloalkanes and a small number of n-isomeric alkanes, which have high melting point and amorphous characteristics. The melting point of microcrystalline wax is generally 54.4 C - 90.6 C. Compared with paraffin wax, microcrystalline wax is tough and not easily broken. Most grades of microcrystalline wax are malleable. In color, the microcrystalline wax is milky white or yellowish. It is white to light yellow small needle-shaped crystal, odorless and tasteless. The main components are high carbon (31) n-alkanes, isomeric alkanes and a small amount of cycloalkanes. It is a high boiling point product obtained by treating the residue of petroleum fractionation with solvent extraction and other methods. It has good adhesion and ductility, not fragile at low temperature, adding liquid oil to prevent oil precipitation. Used as a viscosity regulator of hot melt adhesive, microcrystalline wax is better than paraffin in improving heat resistance, cold resistance, flexibility and bonding strength, but less agglomeration resistance. It can also be used as a protective agent for bonding surfaces.

Microcrystalline wax is mainly divided into three models: no. 70, no. 80 and no. 85. Microcrystalline wax has good oil absorption performance and can form stable and even paste with a variety of solvents and waxes. Microcrystalline wax has emulsifying properties and can be used as processing aids for shoe polish, car wax, polishing wax, floor wax, polishing wax, Chinese pills, protective agents, candles, wax toys, dental materials and cosmetics, etc. In addition, the use of this raw material in the waxed paper formula can make the writing clear and the abrasion resistance significantly improved. Microcrystalline waxes are widely used and are the latest production of synthetic waxes in the 1990s. It can replace the same kind of imported gute wax and reduce the cost by about 50%. It can be used as oil phase raw material of cold cream, lipstick and hair wax in cosmetics. Used as a viscosity regulator of hot melt adhesive, microcrystalline wax is better than paraffin in improving heat resistance, cold resistance, flexibility and bonding strength, but less agglomeration resistance. It can also be used as a protective agent for bonding surfaces.
