Intuitive analysis of the production plant's technological level through the product, to the production plant to understand the process, tooling, equipment, technical strength and quality assurance system is sound or not, or through the collection of information, information to analyze the plant's product quality, through this unit has Testing means, according to the requirements of the drawings for sampling of some projects. price. The price of auto parts is the most sensitive issue. When the same kind of auto parts price is different, some people always like to buy cheaper products. It is necessary to determine the direction of purchase from the combination of physical functions and prices, and to consider price factors on the basis of quality, and to compare prices on the premise of equal quality. If the unit price of a factory is 10 yuan, and the unit price of another product is 9 yuan, the direct cost will be a difference of 10, which is a considerable figure. The spread is one that can't be underestimated. The cumulative number is large. transport. Mainly consider the mode of transport, transport distance, and convenience. Transport means road transport, rail transport, water transport, air transport, etc. There are several ways of transporting products from the production plant to the users. The most cost-effective and shortest time is selected. Transport methods, distances, and convenience levels should be considered comprehensively. Transport issues should focus on transportation costs and transportation time. Transport time includes: First, guarantee supply, and second, cash flow rate. Delivery situation. In the procurement of orders, the contract form is generally used. Delivery status refers to the implementation of the contract by the manufacturer. The supply work is to guarantee the supply of duty, and the delivery situation should be considered as an important factor. Manufacturers that do not implement the contract at all are not included in the selection. The performance of the contract is evaluated based on the percentage of the number of contracts signed and the number of executions.
1-Butanol, also known as N-butanol or N-butanol Alcool, is a primary alcohol with the chemical formula C4H9OH and a linear structure Slovent Raw Material. Isomers of 1-butanol are isobutanol, butan-2-ol and tert-butanol. The unmodified term butanol usually refers to the straight chain isomer.
N-butanol 99.9% occurs naturally as a minor product of the ethanol fermentation of sugars and other saccharides and is present in many foods and drinks.It is also a permitted artificial flavorant in the United States,used in butter, cream, fruit, rum, whiskey, ice cream and ices, candy, baked goods, and cordials.It is also used in a wide Pvc Resin range of consumer products.
The largest use of 1-butanol is as an industrial intermediate, particularly for the manufacture of Ethylene-Vinyl Acetate Butyl Acetate (itself an artificial flavorant and industrial solvent). It is a petrochemical derived from propylene. Estimated production figures for 1997 are: United States 784,000 tonnes; Western Europe 575,000 tonnes; Japan 225,000 tonnes.
