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:Why do tableware usually use ceramics?
Use:1. ceramics for daily use: such as tableware, tea set, jar, altar and basin. Pots, etc..2. art ceramics: vases, sculptures, furnishings, etc..3. industrial ceramics: ceramics used in a variety of industries. It is divided into the following 6 aspects:(1) building a sanitary ceramic: such as brick, drain pipe, brick, wall tile, sanitary and so on;(2) chemical ceramics: acid resistant containers, pipes, towers, pumps, valves, and acid bricks, ash, etc. used in lining reactors;(3) chemical porcelain: Porcelain crucibles, evaporating dishes, burning boats, grinding bodies, etc. used in chemical laboratories;(4) electric porcelain: insulator used for high and low voltage transmission line of electric power industry. Bushings for motors, insulation for insulators, insulators for low-voltage appliances and lighting, insulators for telecommunications, insulators for radios, etc.;(5) refractory materials: refractory materials used in various high-temperature industrial kilns;(6): special ceramic, special ceramic products thrown in various modern industry and advanced science and technology, high alumina ceramic, porcelain, stone magnesium titanium magnesium porcelain stone, zircon porcelain, porcelain, and lithium ferrite, metal ceramic etc..
Q:How to clean ceramic cups?
Can use toothpaste to wash, hey hey, you can also go outside looking for sand, cleaned into the cup, shake the range as far as possible light, and then use water to clear it
Q:What is dry ceramics made of dry building ceramics?
- Outlook: dry milling prospects although dry milling in the country has not yet comprehensive promotion, but the industry for dry milling the prospect that good. The general manager of Keda Electrical Line Engineering Division Chen Shuifu believes that in the current domestic ceramic production system inside, energy-saving potential is the biggest in the raw material preparation, because it revolutionized the current powder preparation process, so the dry milling future will definitely become the direction of the industry.
Q:How to measure ceramic capacitor with pointer multimeter
First, discharge the capacitor (short circuit, two feet). If the pointer has a capacitor, the knob is placed in the appropriate gear (of the capacitance, 223 of which means that the capacitance is 0.22 F) and the capacity is measured;If the pointer table has no capacitor stalls, the most high-end multimeter on the resistance profile (e.g. 10K file or 100K file, such a small capacity, put in the 1K file below is not change), measurement of capacitor discharge, a pointer angle swinging to the right (when a pen eyes to look at the dial, but can not see the pen, because the charging time is very short), then pointer back in situ (because the swing is to charge the capacitor because of full power and resistance value is infinite) said capacitor is good, if the pointer back to in situ, the capacitor leakage, have gone bad. But this method can not measure capacity, can only judge whether the capacitor is good or bad.
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.
View of the market in general, ceramic good, as long as it is metal will inevitably rust. Also, the impurities in the water are relatively high in metal adhesion. In normal use, the ceramic has a longer service life! (recently, the copper shower on the market is made of brass, with relatively rough workmanship and thin and fragile material. The copper shower strictly if wrought copper, polishing, but also through the strict chemical anti rust treatment, the cost is very high.) The thing is not absolute, the real copper shower is good
Q:The difference between ceramic capacitors and ceramic capacitors
Similarly, the dielectric layer is ceramic material ~!
Q:What material does the ceramic brake pad make of?
Ceramic brake pads subvert the traditional concept of ceramic brake pads, which consist of ceramic fibers, iron free fillers, adhesives, and a small amount of metal.Ceramic brake is a brake, many consumers would mistakenly think that originally made of ceramics, ceramic brake is actually from the metal ceramic rather than the principle of non metal ceramic brake pads, due to the high speed heavy braking, high temperature, on the friction surface according to the determination, can reach 800 to 900 degrees, and some even higher. At this high temperature, the cermet will be sintered on the surface of the brake pad so that the brake pads have good stability at this temperature. While the traditional brake pads at this temperature will not produce sintering reaction, because the surface temperatures will make the surface of material melting and even air cushion, which is caused by continuous brake after the brake performance decreases sharply or total loss of the brake.
Q:How about ceramic perm?
Yes, this is the most popular hairstyle today, and many trend girls do
Q:What does "18 heads and 20 heads" mean in ceramic products?
I added a little, you say "head" is mainly used in ceramic tableware in the unit, said how many objects, including bowl, dish, bowl and so on.
Q:What certificate does ceramic export Korea need to do?
1. delivery and inspectionInspection by China import and export inspection agency inspection certificate.2., the implementation of the letter of credit, or to ensure that the other party can pay
