The main uses of pvc plastic particles are divided into:
1.PVC general soft products.
The du extruder can be used to squeeze into zhi hoses,cables,wires,etc.;the dao injection molding machine can be used with various molds to make plastic sandals,shoe soles,slippers,toys,auto parts,etc.
2.PVC transparent material.
After PVC is mixed with additives and plasticized,a three-roll or four-roll calender is used to make a transparent or colored film with a specified thickness.The film is processed in this way to become a calendered film.It can also be cut and heat-sealed to process packaging bags,raincoats,tablecloths,curtains,inflatable toys,etc.The wide transparent film can be used for greenhouses,plastic greenhouses and mulch films.The biaxially stretched film has the characteristics of heat shrinkage and can be used for shrink packaging.
3.PVC coated products.
Artificial leather with a backing is made by coating PVC paste on cloth or paper,and then plasticizing it at a temperature above 100 degrees Celsius.It can also be formed by calendering PVC and additives into a film,and then pressing it with the substrate.Artificial leather without a substrate is directly calendered by a calender into a soft sheet of a certain thickness,and then the pattern can be pressed.Artificial leather can be used to make suitcases,purses,book covers,sofas and car cushions,etc.,as well as floor leather,used as floor coverings for buildings.
4.PVC foam products.
When mixing soft PVC,add an appropriate amount of foaming agent to form a sheet,which is foamed into foam plastic,which can be used as foam slippers,sandals,insoles,and shock-proof cushioning packaging materials.The extruder can also be used to form low-foamed hard PVC boards and profiles,which can replace wood for trial use.It is a new type of construction material.
5.PVC transparent sheet.
The impact modifier and organotin stabilizer are added to PVC to become a transparent sheet after mixing,plasticizing and calendering.Thermoforming can be made into thin-walled transparent containers or used for vacuum blister packaging.It is an excellent packaging material and decorative material.
6.PVC hard board and board.
Stabilizers,lubricants and fillers are added to PVC.After mixing,the extruder can be used to extrude hard pipes,special-shaped pipes and corrugated pipes of various calibers,which can be used as sewer pipes,drinking water pipes,wire casings or staircase handrails..The calendered sheets are overlapped and hot pressed to make hard plates of various thicknesses.The plate can be cut into the required shape,and then welded with hot air with PVC welding rod to form various chemical resistant storage tanks,air ducts and containers.
Doors and windows are assembled with hard special-shaped materials.In some countries,it has occupied the door and window market together with wooden doors,windows,aluminum windows,etc.;wood-like materials,steel-based building materials;hollow containers.
