Product Description

 

This screw rod is made from 99.5% alumina ceramic materials, the use of dry pressing process makes the rod obtain high density and good flexural strength, resulting in better acid corrosion.

On the threaded portion, we use the machining way to make more precise thread size. The thread out of Such processing will get the same accuracy and with metal thread.

We can manufacture products according to your needs, the more common specification is 271mm, below are some of our existing specification.

M6*190, M6*215, M6*247, M6*271, M6*285, M6*296, M8*160, M8*190, M8*215, M8*241, M8*271, M8*285, M8*296

Q:How to identify sanitary ware and other ceramic products good or bad?
Sanitary ware is mainly composed of ceramic sanitary ware and accessories, sanitary ceramics including toilet, wash basin, bidet, and sanitary quality judgment mainly depends on the following aspects: the overall shape: good sanitary ware not only beautiful appearance, but also to meet the human body function, the use of comfort. Ceramic glaze: glaze brand, glaze thickness, as well as firing process, directly determine the effect of glazed ware, the water pipe whether pouring glaze, is an important sign to determine sanitary ware grade. Toilet body: the quality of the body determines the water permeability of the ceramic directly. The length of high temperature tunnel kiln directly determines the quality of the ceramic. The longer the tunnel, the longer the ceramic from heating to cooling, the smaller the temperature in the process of firing, and the product is not easy to crack, and it has the advantages of fast quenching and good heat resistance. In addition, only when the kiln is large enough to fire the high water tank, it will save water and wash it more cleanly.
Q:What are industrial ceramics, including what?
Generally speaking, we specialize in 95 porcelain, that is, more than 95% aluminum content. Industrial porcelain.
Q:Ceramic hot perm and what is the difference? Which effect is good?
Hello, I am a supervisor of Hongkong hairdressing education institution. Let me briefly explain the difference between the two. Perm: it is hard power ripple effect is not flexible, not natural. Ceramic hot: Electric out of the ripple effect is more elastic, corrugated natural. If selected, of course, ceramic hot lot. But the price will be expensive for about one half.
Q:How to judge whether the ceramic cup is poisonous or not?
According to the standard indicators of the state of ceramic production to the production, as long as the ceramic products, especially like ceramic cups and the like necessities index is more strict, the reason why there will be some cheaper ceramic glass or ceramic supplies is because these glass indicators and safety are not very high. The main advantage of these products is relatively low prices, so most consumers in the purchase process will generally choose such ceramic products, especially on the market comparison color cup attract our attention, so consumers in its magical effect under very easy to buy!
Q:The difference between ceramic, enamel, porcelain?
A general term for ceramics, pottery, and porcelain. The traditional concept of ceramics refers to all artificial industrial products made from inorganic non-metallic minerals such as clay. The utility model comprises various articles made of clay or clay containing compounds which are mixed, formed and calcined. The most delicate fine pottery and porcelain belong to its range from the most coarse soil. Its main raw material is the silicate minerals (such as clay, feldspar, quartz and so on) that are taken from nature. Therefore, they belong to the category of silicate industry, such as glass, cement, enamel and refractory materialsEnamel, in fact, is a composite material that combines inorganic glass material by melting it on the base metal and firmly bonding it to the metal. It has two main components: the use of metal materials and enamel enamel (inorganic glass material).A: China is China defined bonechina bonechina is referred to as generic, in animal bone char, clay, feldspar and quartz as raw materials, a kind of porcelain biscuiting after high temperature and low temperature glaze firing two times.
Q:What are ceramic knives used for?
Ceramic knife action: anti magnetic / electrical insulation / Gao Jie clarity / can use as ordinary knife / / but not like ordinary metal knife, blade easy to wear, blunt.
Q:Who invented ceramics?
From the current knowledge of the archaeological materials, the fine pottery has upper Paleolithic dating back 10 thousand years of grey pottery, 8000 years ago Cishan culture of terracotta, with 7000 years of Yangshao culture pottery, with 6000 years of Dawenkou "eggshell black", has 4000 years of Shang Dynasty, white pottery 3000 years of the western Zhou Dynasty and the Qin Dynasty hard pottery, the Terracotta Army, the Han Dynasty, the Tang Dynasty pottery, glazed pottery. In the Song Dynasty, the rapid development of the production of porcelain, pottery industry tends to decline, but there are some special pottery varieties still has its unique charm, like the song, Liao Sancai and Ming and Qing has the teapot, glass, and pottery Shiwan Guangdong flower method, all have a unique style, highly appreciated. But pottery has always been a low-grade product in the initial stage of civilization, and its own defects doomed its fate to be gradually eliminated by history. China is a great invention in ancient Chinese, in the long years of history, diligence and wisdom of the Chinese ancestors point into the territory, wrote the text made great shine with great splendor, contribution to human civilization. Enjoy the reputation of Chinese porcelain, has become the world's major museums in the Pearl, will also be more widely as the research object and China experts and scholars around the world, and by the majority of collectors and ceramic lovers treasure. The invention and development of China's porcelain have developed from low level to higher level, from primitive to mature.

Q:Ceramic knife?! Listen, why are you so fragile? Can you cut bones?

Q:What's the inner core in the shower? Some people say that all copper is good, some people say that the ceramic core is good.
1, it is recommended to use ceramic core.Have the advantages of the 2, the two, copper core capable of sterilization, in the aspect of environmental protection is a good choice, ceramic core strong corrosion resistance, no matter how important is bought is real, because now there are many businesses in the pursuit of higher profits, cut corners on the market, resulting in product quality is no, especially in copper, if mixed with some impurities, it is easy to form the primary cells, produce the redox reaction, is a great harm to the human body.
Q:Principle of reducing burning point of ceramics by cosolvent
In addition, common fluxes are boric acid, borax and other boron oxides, and lead oxides, of course. Boron has a strong fluxing effect with lead.
