Extrusion crosslinking process of one-step silane crosslinked material

Information Source:Henan Huadong Cable Co., Ltd Release date:2014-05-14
Many cable factory using one-step silane crosslinked material voltage power cables and low overhead insulated cable. One step silane crosslinking material without A, B material, without adding any other catalysts and additives (except black and color masterbatch), simple production process, extrusion products, a wide range of specifications, high production efficiency. The basic process is as follows:
 
Extruder: screw for ordinary screw length diameter ratio of 20/1-28/1, isometric ranging from deep; barrel temperature control device to have good; cooling water temperature suggest using piecewise cooling method, reduce insulation stress; when necessary, in the extrusion die with a 40-60 mesh stainless steel screen.

Extrusion temperature setting reference value:

1District 2 District 3 District 4 District 5 District Machine neck Machine head Die
140 155 165 180 190 180 200 210
Extrusion temperature can be adjusted according to the equipment control system error, processing section, extrusion speed; temperature control range can be set to use plus or minus 20 degrees.
 
Crosslinking conditions: can be placed in the 80-90 ℃ hot water pool, can also be placed on the steam pressure of steam room in 1atm. The cross-linking time according to 4h/mm at 90 ℃, speed estimation.
