根据《决策与信息》杂志1988年第7期报导,国家"七五"期间要求主要绝缘材料及支架材料全部采用以玻璃纤维为基本材料的绝缘制品,这样会使近两年市场一直不景气的玻璃纤维产品有新的发展.近两年,全国玻璃纤维产量逐年下降.据统计,1985年全国玻璃纤维产量是71045吨,1986年为66943吨,1987年只有63270吨.1987年除中碱玻璃纱比1986年上升19.8%外,无碱布下降13.8%,无碱玻璃纱下降23%,中碱玻璃布下降15.5%.据有关部门对全国玻璃纤维发展趋势预测,到1990年,我国玻璃纤维总产量将达到10万吨,无碱玻璃纤维及其制品平均年增长 相似文献

Palm oil products in cooking fats 总被引:1,自引:0,他引:1
M. S. A. Kheiri 《Journal of the American Oil Chemists' Society》1985,62(2):410-416
Palm oil and its products are used widely, either on their own or in combination with other oils and fats, to make products
for cooking and other applications such as baking, icing, filling and topping. Palm oil and its products are not only cheaper
to process but also impart into the product the functional properties demanded by some of these applications. Legislation
governing production and marketing of these products in some of the important countries is reviewed. The physico-chemical
characteristics of products marketed in different countries are also presented. Formulations based on palm oil and its products
are suggested to make low or notrans acid fats and high PUFA fats. 相似文献

The addition reactions of ethylene oxide and/or propylene oxide catalyzed by KOH and initiated with compounds containing free hydroxyls are followed by secondary reactions which vary the expected molecular weight. By using ethylene oxide, diols are formed and by using propylene oxide, both diols and unsaturated monofunctional compounds are formed. These products are usually characterized by their hydroxyl number. The average molecular weight is found by taking into consideration the starter functionality only. There are often some behavioral differences among similar products owing to the different quantity and chain length of the secondary products contained therein. The secondary products are analyzed and the quantity of the secondary products were determined from the hydroxyl number values and from the unsaturation of reagents and products. In the case of monofunctional adducts using the calculation method, the results have been experimentally confirmed. 相似文献

Aqueous solution of alcohols and aliphatic amines are oxydized with ozonated oxygen. Formation of aldehydes, ketones, acids and peroxydic products is evidenced in the case of alcohols in concentrated solution. Hydroxylamine oxime and amide are also identified in the case of amines. The formation of condensation products from the amine or the intermediate amide is also seen. In diluted solution, the compounds disappear and certain ozonation products are formed but not the products of condensation. 相似文献

Use of vegetable proteins in meat products in Denmark is discussed with special reference to economy. Aspects of price vs.
quality also are discussed, and performance criteria in the evaluation of vegetable protein products are proposed. Examples
are given of recipe optimization with soy protein products, and finally the market perspectives are outlined. It is emphasized
that no conflict is seen between the use of vegetable proteins in meat products and agricultural or consumer interests. 相似文献

Fresh aquatic products are rich in nutritional compounds and are an important source of good protein for humans. Dehydration processing technologies of aquatic products used in practice are a mix of old and new technologies. With the rapid development of drying technologies and steadily increasing living standards, drying processing techniques as well as types of products produced have changed fundamentally. Two broad types of dried aquatic products are commercially available on a large scale: traditional products and snack foods. In this article, the development of dried aquatic product processing technologies will be expounded along with an overview of the necessary quality attributes and control strategies to produce high-quality dried products of aquatic origin. 相似文献
