How can pc plastic turn yellow?

1. Use dioxygenated milk (12% concentration) Dioxygenated milk (hydrogen peroxide) is highly oxidizingPC fiber adding what to turn white, can be broken down by decomposing yellowing substancesPC fiber adding what to turn whiteOrganic matter to achieve bleaching. Apply the dioxygen milk evenly on the yellowed areas, and control the thickness to 1-2 mm to avoid uneven reactions caused by excessive thickness. After applying, wrap the plastic in a fresh-keeping bag and expose it in the sun for 3-5 days. Ultraviolet rays in the sun accelerate the decomposition of dioxygen milk and enhance the bleaching effect.

2. Yellowing plastic can be restored to white by the following methodsPC fiber adding what to turn white: Disinfectant water soaking method Mix disinfectant water and water at a ratio of 1:200, pour into a container, put in yellowing plastic products, and soak for about 30 minutes. Stains will naturally fall off and at the same time serve as a disinfectant. After soaking, rinse thoroughly with clean water to avoid residual chemical substances. This method is suitable for plastics with light surface stains, such as toys, daily necessities, etc.

3. The yellowing problem is not simply caused by the screw of the machine, but more due to the degradation caused by friction of the plastic substrate caused by high temperature. To solve the yellowing problem, try to reduce the injection molding temperature, which helps reduce the degradation of plastic at high temperatures. The yellowing problem may stem from the excessive temperature of the PC material during the drying process or the excessive drying time, causing the material to turn yellow.

Tpu coated pc fiber adding process steps

The complete process steps of TPU-coated PC fiber adding are divided into four core steps: preliminary preparation, injection molding, post-treatment and quality inspectionPC fiber adding what to turn whiteAmong them, coating fit is a key indicator of process control, material pretreatment during the preliminary preparation stagePC fiber adding what to turn white: PC fiber adding materials (generally glass fiber content 10%-30%) and TPU materials need to be dried at 80-120℃ for 4-6 hoursPC fiber adding what to turn whiteRemove moisture from raw materialsPC fiber adding what to turn whiteAvoid bubbles and layering problems during the encapsulation process.

The soft and hard glue wrapping process mainly involves secondary molding molds and two-color molds. Secondary forming moldPC fiber adding what to turn white, that is, the main application method of soft glue wrapped in hard glue. Commonly used rubber materials such as artificial rubber, TPU, TPR, TPE, etc., while hard glue is made of ABS, PC and other materials. This process can be divided into two types: one is a two-color mold. This mold is molded twice on an injection molding machine, and the product is molded after being molded once.

Principle of true glue: Based on the compatibility of soft glue (TPU) and hard glue (or soft glue) during the softening and melting processes.

Introduction to the encapsulating process The encapsulating process is to wrap one material on the surface or inside of a product made of another material through injection molding to form a single component made of dual materials. Materials are bonded through physical or chemical bonding. Term 1 One of the substrate injection materials. As a skeleton or body, common materials include ABS, PA6/PA66-GF, PP, PC, PC+ABS, etc.

At the same time, the difference in shrinkage rates between two different materials must be accurately calculated and compensation must be reserved in design, otherwise the finished product can easily crack or wrinkle due to internal stress. Material selection directly determines the performance and bonding effect of the coating layer. Generally, the internal substrate is made of highly rigid engineering plastics such as ABS and PC to provide support, while the outer adhesive layer is mostly made of soft elastomers such as TPE and TPU to provide comfortable touch, slip resistance or shock absorption properties.

How to bond silicone and plastic PC? What glue is used?

1. Dispensing and bonding: Apply quick-drying adhesive (such as 601) to the surface of silica gel or PC (choose one side), press the two materials for a few seconds, and place it at room temperature for 1 minute to see the bonding effect. Advantages: Fast bonding speed and support dispensing solutions. Strong viscosity, reaching the extent of silicone tear. High and low temperatures range from-40 ° C to 100°C. Disadvantages: When the silicone gel is thin, the bond may turn slightly white and hard (optional low-whitening quick-drying glue for improvement).

2. Bonding of TPU, nylon, glass fiber, glass and other materials, including compounds that require or do not require secondary vulcanization.

3. The core method of bonding silicone and plastic: use special silicone glue or silicone adhesive. Recommended glue type Silicone glue: It mainly relies on contact with water molecules for curing and is widely applicable. It is divided into room temperature curing type (easy to operate) and high temperature curing type (high bonding strength). It can bond silica gel and a variety of plastics (such as ABS, PVC). After curing, it has good transparency and anti-aging.

4. Normal temperature bonding: Silicone glue is a type of adhesive used in silicone rubber for bonding silica gel to silica gel, silica gel to similar plastics. It cures by contacting water molecules on the surface of the bonded or sealed object or water molecules in the air.

10% pc fiber added using Zhong Yuan Chemical, which toughening agent can be recycled more than 5 times without cracking

Zhong Yuan Chemical's M-72M-701 two MBS core-shell structure toughening agents can be used in the 10% PC fiber adding formula. In theory, they will be recycled more than 5 times without cracking. M-724: It is a toughening agent for MBS core-shell structure with excellent impact resistance. It has less impact on flame retardancy in flame retardant PC alloy formulations and has excellent chemical resistance.

Zhongyuan Chemical MBS M-724 toughening agent can be selected to meet the need of 10% PC fiber recycling more than 5 times without cracking. Basic product information The toughening agent is a white high-flow powder polymer with methyl methacrylate-butadiene-styrene (MBS) core-shell structure.
