Self-Adhesive TPO Waterproofing Membrane Production Line

High quality Self-Adhesive TPO Waterproofing Membrane Production Line  is offered by China manufacturer Haiming Machinery. Buy Self-Adhesive TPO Waterproofing Membrane Production Line  which is of high quality directly with low price.The self-adhesive TPO waterproofing membrane production line mainly includes the following parts:

Feeding system

Function: Various raw materials required for the production of self-adhesive TPO waterproofing membranes, such as thermoplastic polyolefin resin particles, antioxidants, anti-aging agents, softeners, etc., are accurately delivered to the extrusion system according to a certain formula and proportion.

Requirements: Measuring accuracy reaches level 1, vacuum feeding and adjustable suction to ensure the stability and accuracy of raw material supply, and avoid product quality problems caused by unstable feeding, such as appearance defects and uneven thickness.

Extrusion system

Function: Heating, plasticizing and extruding the raw materials sent by the feeding system is one of the core equipment for the production of self-adhesive TPO waterproofing membranes. Through the rotation of the screw and the heating of the barrel, the raw materials are melted under high temperature and high pressure, and extruded from the head under the push of the screw.

Requirements: Automatic temperature control, temperature deviation is controlled within±2℃to ensure the plasticization effect and extrusion quality of raw materials; stable pressure, equipped with BM rear exhaust structure, single screw length-diameter ratio is not less than 35:1, twin screw length-diameter ratio is not less than 50:1, to ensure the uniformity and continuity of the extrusion process.

Paving system

Function: Place reinforcing materials or covering layers such as polyester mesh, fabric fiber or aluminum film on the surface of the extruded TPO coil, and lay these materials evenly on the coil at the set speed and tension through the laying system, and compound them with the extruded TPO material to enhance the strength and performance of the coil.

Requirements: The laying speed is constant and controllable to ensure the composite quality of the reinforcing material and the extruded coil, and avoid problems such as wrinkles and deviation.

Calendering system

Function: Calender the TPO coil extruded and compounded with reinforcement materials to make it uniform in thickness and smooth in surface, and further improve the density and strength of the coil. Through the pressure and temperature control of the calendering roller, the coil reaches the specified thickness and dimensional accuracy.

Requirements: Automatic temperature control of the mold, accuracy±5℃; adjustable pressure and water temperature of the calendering roller, temperature deviation±2℃, to ensure the stability of the calendering process and product quality.

Thickness measurement system

Function: Real-time online detection of the thickness of the self-adhesive TPO waterproofing coil to ensure that the product thickness meets the standard requirements.

Requirements: The detection accuracy reaches 0.01mm, the detection frequency is not less than 1 time/10m, the full width detection is not less than 10 points, and it can automatically alarm when exceeding the set value, and automatically save the thickness measurement record, so as to timely discover and adjust the thickness deviation in the production process.

Cooling system

Function: Cool and shape the self-adhesive TPO waterproofing membrane after calendering, so that it can quickly reduce the temperature and maintain the stability of shape and size.

Requirements: It has tempering function, automatic temperature control, controllable cooling program, and reasonable control of cooling speed and temperature to avoid internal stress, deformation or other quality problems of the membrane due to uneven or too fast cooling.

Reeling system

Function: Reel the cooled self-adhesive TPO waterproofing membrane neatly and tightly into a roll for easy storage, transportation and subsequent use.

Requirements: Controllable tension, automatic weighing, length measurement, automatic curling, to ensure that the rolled membrane has moderate tightness and neat end surface, and avoid problems such as loose membrane, deviation or uneven end surface.
