Product Description
Made in China glass raschig ring for chemical engineeringFrom Wikipedia, the free encyclopedia:Raschig rings are pieces of tube (approximately equal in length and diameter) used in large numbers as a packed bed within columns for distillations and other chemical engineering processes. They are usually ceramic or metal and provide a large surface area within the volume of the column for interaction between liquid and gas or vapour. Raschig rings are named after their inventor, the German chemist Friedrich Raschig.[1]
They form what is now known as random packing, and enabled Raschig to perform distillations of much greater efficiency than his competitors using fractional distillation columns with trays.[1]
In a distillation column, the reflux or condensed vapour runs down the column, covering the surfaces of the rings, while vapour from the reboiler goes up the column. As the vapour and liquid pass each other countercurrently in a small space, they tend towards equilibrium. Thus less volatile material tends to go downwards, more volatile material upwards.
They are also used for devices where gas and liquid are put in contact for purposes of gas absorption, stripping or chemical reaction, and as a support for biofilms in biological reactors.
Raschig rings made from borosilicate glass are sometimes employed in the handling of nuclear materials, where they are used inside vessels and tanks containing solutions of fissile material, for example solutions of enriched uranyl nitrate, acting as neutron absorbers and preventing a potential criticality accident.[2
Material: high borosilicate glass,
ShanDong HonHai Industrial Group Company Limited who produces and supplies borosilicate glass tube, rod and its related glassblowing articles, glass ceramic, borosilicate glass sheets, borosilicate moulded glassware, pharmaceutical glass packaging, lamp lighting glass shell and daily consumer glassware. Jinan HonHai Glass Company Limited, as a member of ShanDong HonHai Industrial Group Company Limited, is handling international business of the whole group.
Ø Division for borosilicate glass tube, rod and its related glassblowing articles
We started to manufacture borosilicate 3.3 colored and clear glass tubing, rod (Vello & Danner) and its related glassblowing articles since 1994 through importing Japanese NEG's and Germany equipment & technology. Now we have annual capability to draw glass tube over 150, 000 metric tons, which makes us the leading Chinese manufacture in this field. Thanks to our continous process improvements, we have been drawing glass tube with highly precise dimensions in China.
We also redraw (secondary processing on tubing) high precision bore glass & quartz tube for optoelectronic, fibre optics telecommunication, medical and other special applications.
Besides, we make scientific laboratory glassware, heat resistant glass tea & coffee sets, glass bong water pipes, glass baby feeding bottles, lamp glass shell and others glassblowing products.
Ø Division for borosilicate moulded glassware
Due to our expertise in electrically melted glass furnaces control technology, we set up a new factory in the year 2001 to make heat resistant baking dishes, Casseroles, food storage glass jars and others that are oven, microwave, freezer (refrigerator), dishwasher free.
Now we have annual capability around 5, 000 metric tons.
Ø Division for pharmaceutical glass packaging
From the year 1996 we enter into pharmaceutical glass packaging industry, produce neutral borosilicate pharmaceutical glass tube USP TYPE I, tubular glass vial & ampoule, glass cartridge, glass prefillable syringes.
Now we have annual turnover around US dollar thirty million.
Ø Division for lamp lighting glass
In the year 1999 we set up factory for making lamp lighting glass including soda lime glass tube, lead glass tube, lead free glass tube, lamp & lantern glass cover/shade/shell/globe/chimney
Ø Division for daily consumer glassware
In the year 2005 we expanded our production to make glass cosmetic containers, glass kitchenware and Tableware.
Particularly, we've successfully developed flat borosilicate 3.3 floated glass sheet and glass ceramic which enjoys a good reputation in the United States and Europe.
Our factories are equipped with advanced machinery with production know-how, strict and complete quality management and supervision system as well as friendly customer service. Holding a business principle of "Honesty, Cooperation, Win-Win", we concentrate on continuous quality improvement and upgrade. We take it as our responsibility to satisfy customers' requirements, and innovate market demand.
We well know about glass and respect customers' requests. We will improve, upgrade and innovate products all the time.
Let us rethink, rediscover and reinvent glass!
