The materials of dry-mixed mortar, has been largely used as the development of energy saving building and environmental protection. So understanding the mixed characteristic and disciplines of this materials, which can instruct production and practice, becomes more and more important. This article indicates the mixing degree of dry-mixed mortar by pyoktanin blue method, researches the mixing effect by drum-type blending machine. And also together with the basic discipline curves, the article analyzes the mixing effect by mixing time, rotation speed, sand of modulus fineness, loading factors, etc. The research shows the degree of mixing changes periodically as mixing time changes. But all of rotation speed., sand modulus fineness and loading factors have extreme points on the curves, the points mean the best mixing effect for the material.

乳白玻璃是乳浊玻璃中的一种,外观呈现乳白色.在玻璃本体中产生高分散性玻璃液滴或析出晶粒,由于其与玻璃本体的折射率存在差异,光线照射后产生散射而呈现乳白色光. 从公元14世纪,我国就开始应用坩埚炉熔制乳白玻璃,主要用于制造玻璃工艺品.解放后,开始陆续出现池炉熔制乳白玻璃,用于制造玻璃酒瓶和化妆品瓶. 目前,我国乳白玻璃厂大都以氟化物(冰晶石、氟硅酸钠、萤石、氟化钠)作为乳浊剂,尽管氟化物乳、白玻璃已经有几十年的火焰池炉生产历史,但是能够生产高品质乳白玻璃的企业并不多,在此结合笔者的切身经验,探讨如何稳定和提高氟化物乳白玻璃在火焰炉中的生产.

The mix mechanism of helix mixer and cylinder mixer and researched their effects on cement-sand system,fibre system and light skeletal material system.Proved evidences of improvement and lectotype of mixer for solid material.

Comparison has been done between wall energy-saving reconstruction of existing heating building and wall energy-saving construction of new building. Wall structure, construction environment and construction period are discussed. Requirements of exterior wall adhesive strength, construction environment and construction period are analyzed. Finally, the technological route suited to implement of energy-saving reconstruction for exterior wall insulation systems is pointed out.
