application	The fields with low/no foam requirements for polyvinyl alcohol aqueous solutions, especially in the paper and textile industries.		This product is used as an anti collapse additive in the process of oil and gas drilling, which can effectively prevent drilling fluid filtrate from invading shale, thereby achieving the effect of preventing wall instability and even wellbore collapse. This product has good anti collapse performance as an oilfield additive and has been successfully applied in China.		The conventional 088-05 is applicable to all fields RY-ll. It is especially recommended to be used as the raw material for the production of environment-friendly panel glue, PVAc or VAE lotion protective colloid.	The conventional 088-20 is applicable to all fields RY-III, and is especially recommended to be used as the raw material for the production of environment-friendly panel glue, PVAc or VAE lotion protective colloid.	This product is a high-performance polymer with strong adhesion, low dosage, high green yield, low ash content, and stable sintering volatilization. It evaporates smoothly in the temperature range of 150-450 ℃. Other adhesives in the existing magnetic material industry may suddenly evaporate in large quantities during the sintering and volatilization process, resulting in small cracks and damage to the product. However, this product effectively avoids this problem. Products produced using this product have almost no cracking or damage to the magnetic material, significantly improving the performance and quality of the product.	1. The prepared solution can be used as thickener and anti sagging agent of lotion. 2. Combining with conventional PVA for paper surface sizing can improve paper strength and ink absorption. 3. The cross-linking performance of the product can be used to prepare various water-resistant adhesives.
