Amount controls below 0.1%；
(2) batch mixing: the degradable polypropylene granule through step (1) and plasticiser, antibacterial, clarifier mixing are added reactor
In, purpose granule, at 175-185 DEG C, is melted into molten condition under conditions of stirring by the temperature control of reactor；
(3) modified: by the material modified fused solution adding in step (2), and vacuum stirring, mix homogeneously；
(4) feed: the raw material mixing is put in extruder, starts extruder heating function, by extruder one area to 6th area
Heating-up temperature all control at 200-240 DEG C, heat time heating time be 40-65 minute；
(5) extrude: open extruder main frame, suction pipe blank is extruded, and opens air pump, the pressure of air pump is set as 5-7mpa；
(6) stretching, cooling: the material that step (5) is extruded is stretched to bosh, and the water temperature of bosh controls in 12-42
At DEG C, cool time is 2-8s；
(7) cut: the material after cooling is cut；
(8) sterilize: the material through step (7) is carried out disinfection by ultraviolet light, disinfecting time is 15-20 minute, ambient temperature controls
For 20-40 DEG C；
(9) case: automatically packed with platoon automatic packaging machine, then cased, being disappeared with ozone again after vanning
Poison.
6. according to claim 5 a kind of production technology of transparent beverage suction pipe it is characterised in that described step (5) extrusion
