1. Fault Phenomenon: Bleeding
Causes of Failure:
(1) The edges of printed graphics may bleed due to the use of inappropriate dyes in the ink.
(2) Improper pigment usage or degraded ink can also cause bleeding.
(3) Excessive dilution materials, especially those that are not compatible with the ink, may lead to this issue.
Solutions:
(1) Add a coupling agent or gold oil to the ink to improve adhesion.
(2) Use solvent-based pigments (such as alcohol solvents) or replace the ink if necessary.
(3) Reduce the amount of diluent used and ensure compatibility between the diluent and the ink.
2. Fault Phenomenon: Residual Odor on the Product
Causes of Malfunction:
The residual odor in the printed image of the woven bag printing machine is often caused by poor ink formulation, raw materials containing odors, or ink degradation leading to unpleasant smells.
Solutions:
Avoid using inks with strong odors whenever possible. If necessary, add a fragrance (masking agent) to the ink to prevent impurities from affecting its quality. During the production and storage of ink, pay attention to the solubility and compatibility of the mixed solvents with the resin. Store the ink in a cool and well-ventilated area to maintain its quality.

UV accelerated aging test chamber
A UV accelerated aging test chamber is a specialized piece of equipment used to simulate the effects of long-term exposure to ultraviolet (UV) radiation on various materials and products. It is commonly used in industries such as automotive, aerospace, cosmetics, and electronics to evaluate the durability and performance of materials under accelerated aging conditions.
The chamber typically consists of a controlled environment with UV lamps that emit high-intensity UV radiation, simulating the UV exposure that materials would experience over an extended period. The UV lamps produce a spectrum of UV light, including UVA, UVB, and UVC, which can be adjusted to mimic specific environmental conditions.
The test specimens or products are placed inside the chamber, and the UV lamps are turned on to initiate the aging process. The chamber may also incorporate other environmental factors such as temperature, humidity, and airflow to simulate real-world conditions more accurately.
The accelerated aging process allows manufacturers to assess the effects of UV radiation on the materials' physical, chemical, and mechanical properties. It helps determine the degradation, discoloration, embrittlement, cracking, or other changes that may occur over time due to UV exposure.
UV accelerated aging test chambers are essential for quality control, product development, and compliance with industry standards and regulations. They enable manufacturers to evaluate the performance and lifespan of materials, optimize formulations, and make informed decisions about product design, materials selection, and UV protection measures.
