Cable coating crosslinking agent

Cable coating crosslinking agent. Crosslinking cable production process by the cable industry way is divided into three categories: the first kind of peroxide chemical crosslinking, including saturated steam crosslinking, inert gas crosslinking, molten salt crosslinking, silicone oil, crosslinking, adopt the second domestic namely dry chemical crosslinking; The second type of silane chemical crosslinking; The third kind of irradiation crosslinking.

Compounds by using peroxide crosslinking agent of polyethylene insulation material, through three layers co-extrusion complete shield conductor, insulation, insulation shield after extrusion, continuous evenly by crosslinking of high temperature and high pressure nitrogen seal tube to complete the crosslinking process. The heat transfer media is nitrogen (inert gas), and it has excellent performance and production range of 500KV.

By using silane crosslinking agent polyethylene insulation material, by way of 1 + 2 extrusion complete with shielding layer, insulation, insulation shield after extrusion, will have the cooling plate insulation wire core in 85-95 ℃ hot water for hydrolysis of crosslinking, because the water content in wet/cib affect insulation layer. The general maximum voltage level is only 10KV.

The application of a chemical crosslinking, irradiated crosslinked functional parent particle. At present, the use of mother particles with cross-linked polyethylene cable function, can be in ordinary polyethylene cable materials to add a small amount of this master particles, extrusion of cable can be crosslinked cable.

There are three kinds of cable crosslinking functions: chemical crosslinking function, electron beam irradiation crosslinking function, ultraviolet light irradiation crosslinking function.

The chemical crosslinking cable USES the crosslinked functional parent particle, the type: DH -125y, and the dh-125y chemical crosslinking functional parent particle is a colorless LLDPE plastic particle. The cable factory can only buy the general LLDPE polyethylene ordinary plastic particles in the market, such as LLDPE7042 and so on.




Chinese name: Diethyl toluene diamine(DETDA)

Diethyltoluenediamine packing： net weight 200KG/ galvanized iron drum (a small cabinet pallet loaded 16 tons), 1000KG/IB barrels (a small cabinet loaded 18 tons or 23 tons of ISOTANK).


Add 1 kg in 25 kg plastic particles LLDPE7042 function of DH - 125 y mother particle, after turning by hand, it directly into put cable wire extrusion machine, extrusion cable, which made the cross-linking wire and cable. This functional parent can produce 35KV and the following cable cables.

The electron beam irradiation crosslinked cable is used in the crosslinked functional parent particle, the model: DH -125df, and the dh-125df electron beam irradiation crosslinking functional parent particle is a colorless LLDPE plastic particle. Add 1 kg DH - 125-7042 plastic particles df function mother particles, after turning by hand, it directly into put cable wire extrusion machine, extrusion cable, by the electron beam irradiation is made into the cross-linking wire and cable. This function mother particles can produce environmental long-term working temperature at 125 ℃ of crosslinking wire and cable.

The uv-irradiation crosslinked cable is used in the crosslinked functional parent particle, the model: DH -125zf, and dh-125zf, which is the non-color LLDPE plastic particles. Add 1 kg DH - 125-7042 plastic particles zf master particles, after turning by hand, it directly into put cable wire extrusion machine, extrusion cable, after uv irradiation is made into the cross-linking wire and cable. This function mother particles can produce long-term working environment temperature in 125 ℃ crosslinking wire and cable.

The cable production plant is directly used, which is cheaper than the market purchase chemistry, irradiation crosslinked polyethylene cable. The special materials for the purchase of chemical and irradiated polyethylene cable in cable production plant require the inquiry, ordering, production and transportation of the period of a week or so.

With the dh-125 functional parent particles, five minutes of preparation can be made directly after the production plan is determined. Cable factory can adjust their varieties, hardness: DH - 125 master particles, not only can add to the general polyethylene PE particles, can also be added to the didn't have the common cable cross-linking sexual material particles, make originally does not have the properties of crosslinked ordinary plastic particles, cable into crosslinked PVC compound.
