Plasticizer is widely used in industrial production of polymer materials, also known as plasticizer. Any substance added to a polymer material that increases the plasticity of the polymer is called a plasticizer. Plasticizer can improve the performance of polymer materials, reduce production costs and increase production benefits. [1] is a kind of important additives, chemical products as additives commonly used in plastics, concrete, mortar, the material such as cement, gypsum, cosmetic and detergent, especially in PVC plastic products, in order to increase the plasticity of the plastic and improve the strength of the plastic, you need to add phthalic acid ester, sometimes its content can be up to 50% of the products. Weakened the effect of plasticizer mainly resin molecular valence bond between time, increase the mobility of the resin molecular bonds, reducing resin molecular crystalline, increase the plasticity resin molecules, enhanced the flexibility, easy to machining, can legally used for industrial purposes, widely exists in food packaging, cosmetics, medical equipment, water and environment. Such as plastic wrap, food packaging, toys and so on.

How to Strengthen the Management of Raising Fertility
It usually takes 2 to 3 years from the time oyster cultured pearls are implanted for the pearl-growing process until the pearls are finally harvested. This is a lengthy and complex procedure, requiring careful and continuous management throughout the entire period.
After the implantation, the oysters need to be placed in clean water for a certain period to allow their wounds to heal and their health to recover. Once they are stable, they are moved into the breeding area. It's common for some oysters to vomit or even die within the first month after the operation, especially during the early stages of nutrient enrichment. Therefore, it's crucial to monitor them closely and take prompt action if any issues arise.
Farmers should apply both organic and chemical fertilizers regularly to enrich the aquaculture environment, ensuring that the oysters have access to sufficient nutrients that they can easily absorb. This helps support their growth and improves the quality of the pearls being formed.
In closed water systems where there is no natural water flow, it's essential to increase water exchange, inject fresh water, and oxygenate the system regularly. This helps prevent oxygen deficiency and reduces the risk of bacterial infections, which can negatively affect the oysters and the developing pearls.
When hanging and raising pearls, the depth at which the rafts are placed must be adjusted according to changes in water level and temperature. Regular cleaning of the cages and removal of any attached organisms or debris on the oyster shells is also necessary to maintain a healthy environment and promote optimal pearl development.
Overall, successful pearl farming requires not only patience but also a deep understanding of the oyster's needs and the environmental conditions that influence their growth. Proper care and consistent monitoring are key to producing high-quality cultured pearls.
