Advance in rotary manner so that the air in raw material is extruded, the tightness degree higher of raw material, the separation in arc guide piece
Plate will be divided into feed liquor storehouse and go out liquid storehouse in shell, coolant flows under the action of demarcation strip from feed liquor storehouse, from going out the outflow of liquid storehouse,
Coolant cools down molding raw material before raw material are gone out, and reduces the deformation quantity of tubing so that the ingredient of tubing is tight
Close degree higher；
S4：Surface spraying functional layer：It is molded protection blank pipe after cooling to squeeze out from discharge port, according to use demand, to protecting
The outer wall for protecting blank pipe carries out spraying function coating, can be used after drying.
Preferably, antifoaming agent, thickener are additionally added in raw material in the step S1.
Preferably, the antifoaming agent, thickener are respectively polypropylene glycerol aether, attapulgite.
Preferably, 30-35 minutes are kept the temperature in melting furnace after the step S1 Central Plains material molten.
Preferably, the functional coating is the one or several kinds in erosion resistant coating, anti oxidation layer, anti-static coating.
Preferably, drying in the step S4 is dried in thermostatic chamber, and the indoor temperature of constant temperature is Celsius for 45-50
Degree.
Compared with prior art, the beneficial effects of the invention are as follows：The manufacturing method of the fiber optic protection blank pipe, is squeezed by spiral
Go out formula mode will protect blank pipe it is closely basic so that the tightness degree between raw material is preferable so that the quality of finished product compared with
Height, the setting of functional coating so that protecting the characteristic of blank pipe enhances.
