088-05 Partially Hydrolyzed Polyvinyl Alcohol For Seed Coating

Introduction

PVA is a basic chemical material with great potential for development, it has good spinning property, film-forming, and adhesion, and it is widely used in the fields of chemical industry, textile, plastics, papermaking, tanning, bonding, and construction. It has the advantages of easy degradation and pollution-free environment and has a wide space for industrial development.

Through continuous technological innovation, technical transformation, our company's PVA production process is becoming more perfect, master the production of a large number of PVA core technology, can produce different polymerization degree, different alcohol solution degree PVA products. The production process comprehensively uses PLC and DCS Distributed system control technology, through the ISO9001 Quality Management system and ISO14001 Environmental management system certification.

Companies adhere to Low-carbon economic development, the wholly-owned subsidiary of Guangxi Guang-Wei Chemical Co., Ltd. The use of local rich sugar cane resources to produce PVA, to create a calcium carbide acetylene method and oil, natural gas ethylene law other than the third raw material line for the sustainable development of enterprises lay a solid foundation.

Customization

HUAMAO® can customize according to customer demand, production of goods.
1. HUAMAO® can customize the packaging according to the customer's requirements.
2. HUAMAO® can produce different physical forms of PVA: flocculent, flaky, powder.
3. HUAMAO® can process various sizes (mesh 80 100 120 160 etc.).
4. HUAMAO® can produce PVA which is the special technical index(alcoholysis degree and viscosity), according to the customer’s demand.

Seed coating technology can be divided into seed pelleting technique (pelleting) and seed coating technology (film coating) according to the material properties (solid or liquid). Seed-pelleting technology is a special pellet material that is wrapped on the seed surface by mechanical processing and processed into a smooth, particle-like pill (pellet) (or seed pill). Seed coating technology is the seeds and special seed coating agent according to a certain "drug ratio" fully stirred mixing, so that each seed surface coated with a layer of uniform drug film (without increasing the volume), the formation of coating seeds (or coated seeds). Compared with traditional seed-processing technology, seed-coating technology has many incomparable advantages: 1. To ensure the seedlings complete, regular and strong; 2. To reduce the seeds and medicine so as to lower production costs; 3. to protect the environment; 4. To manage the seed market.

Seed coating Agent is a new type of milk paste, which is made of auxiliary auxiliaries, such as the film-forming agent. The seed coating agent is glued to the seeds with a film-forming agent, which is quickly solidified into an even film and is not easy to fall off.

There are four major types of seed coating agents in the world: physical type, chemical type (medicine fertilizer type), biological type (hormone type) and special type (Yi oxygen, water absorption function, etc.), many foreign for a single dosage form, such as the United States FMC Company's furan Dan 35ST for a single insecticide type, friends Lee antecedents of the company's WEIFAO 200 for a single bactericidal formulations.
At present, China has developed a composite seed coating agent, bio-type seed coating agent more than 20 formulations, can be used in corn, wheat, cotton, peanuts, rice, soybeans and other crops, 9 of the dosage forms have been put into production.

The main ingredients of seed coating agent include the active combination (pesticide, fertilizer, hormone), colloid dispersant (Polyvinyl acetate emulsion emulsifier and polyvinyl alcohol), film-forming agent (PVAC, PVRN, etc.), osmotic agent, suspending agent, stabilizer, preservative, filler, warning color, etc.
