Modified fiber PA6 is to add glass fiber or other reinforcing materials to the PA6 base material to improve the strength, stiffness, heat resistance and wear resistance of the material. The following is an introduction to the production process, quality assurance measures, uses and precautions of modified fiber-added PA6.
Production Process
The production process of modified PA6 is generally divided into two steps: preparation of modified PA6 premix and extrusion molding. The key to preparing the modified PA6 premix lies in the control of the ratio of fiber addition and basic material, as well as the mixing uniformity of fiber addition and base material. In the process of extrusion molding, parameters such as extrusion temperature, extrusion pressure and speed need to be controlled to ensure that the size and surface quality of the extruded product meet the requirements.
Quality Assurance Measures
In order to ensure the quality of modified fiber PA6, the following measures need to be taken:
(1) Strict screening and control of raw materials to ensure the quality and stability of raw materials.
(2) When preparing the modified PA6 premix, it is necessary to ensure the mixing uniformity of the fiber addition and the base material, so as to avoid the problem of inconsistent strength and stiffness caused by uneven fiber addition.
(3) During the extrusion molding process, parameters such as extrusion temperature, pressure and speed need to be strictly controlled to ensure that the size and surface quality of the extruded product meet the requirements.
(4) Carry out strict quality inspection of finished products, including inspection of mechanical properties, physical properties and chemical properties, to ensure that the quality of products meets international standards and customer requirements.
use
Modified fiber-added PA6 is widely used in auto parts, electronic appliances, mechanical equipment, aerospace and other fields, and is mainly used to manufacture parts and components that require high strength, high stiffness, heat resistance and wear resistance.
Precautions
When using modified fiber PA6, you need to pay attention to the following:
(1) Storage: Modified fiber-added PA6 should be stored in a dry, cool and ventilated environment, avoiding direct sunlight and high temperature and high humidity environment, so as not to affect its performance.
(2) Processing temperature: When processing modified fiber-added PA6, it is necessary to control the processing temperature according to the type and characteristics of the specific material to avoid thermal decomposition and material deterioration.
(3) Mold design: When manufacturing modified fiber reinforced PA6 parts, it is necessary to design the mold to ensure that the size and surface quality of the product meet the requirements, and to avoid defects such as burrs and bubbles.
(4) Injection molding machine debugging: When debugging the injection molding machine, it is necessary to adjust the parameters of the injection molding machine according to the type and characteristics of the material to ensure that the injection molded products meet the requirements and avoid problems such as bubbles and shrinkage cavities.
(5) Pay attention to safety: During the production and processing of modified fiber-added PA6, it is necessary to pay attention to safety and take necessary protective measures to avoid injuries and accidents caused by chemicals, high temperature and other factors.
In short, modified fiber PA6 is an important engineering plastic with broad application prospects and market demand. In the process of production and processing, strict quality assurance measures and precautions need to be taken to ensure that the quality and performance of products meet international standards and customer needs.
