What is the refractive index of white fused alumina compared with that of glass?

The refractive index of fused alumina is approx. 1.76, whereas that of normal glass types is approx. 1.4. The closer the refractive indices are to each other, the more transparent the system (e.g. varnishes).

What does the bulk weight indicate and what impacts the bulk weight?

According to the FEPA, the bulk density of an abrasive is the quotient of the mass and the volume a grain type poured out in a particular manner will occupy. The bulk density, also called bulk weight, is

What are the three basic raw materials used in the manufacture of coated abrasives?

Grain – a synthetic or natural abrasive; Bond – an adhesive that permanently bonds the backing to the abrasive; Backing – a backing that the abrasive is bonded to

How is fused alumina obtained?

Raw materials containing aluminium oxide are electrothermally melted at a reaction temperature of more than 2,000 °C to produce the various fused aluminas. Different starting materials are used depending on the desired type of fused alumina. For instance,

Are you a manufacturer or trader ?

Yeah, We are the manufacturer of BFA, WFA, GC. Also,we had good business relationship with others abrasive media & refractory raw materials manufacturer . more over we have QC department which make strict inspection on goods quality, packing,

Can you customized quality, size, package according to customer?

Yes, of course. The OEM is available. We will do the creation in your requirement and make ur image come true.

Do you test all your goods before delivery?

Yes, we have 100% test before delivery

Do you have stock of abrasive media or refractory materials ?

Yeah, we have many stock .Just let us know the products you’d like or interested, then we can sent you the full information of the stock at once.

How do i prevent moisture contamination in the abrasive?

Moisture contamination is the number one reason customers call Technical Support. Fortunately, it is usually preventable. There are 4 key ways to keep your abrasive free of moisture:1.Store abrasive properly and always make sure bottles are tightly closed

Sample cost is refundable or not?

Yes, Sample cost below 5 kgs can be refunded when bulk order confirmed,But freight cost for more than 1kg don’t be refunded.

Is sample parts testing available?

MicroBlasting is extremely efficient and precise, so it is hardly likely you will need to recycle abrasive, but it is important to know the risk involved. Unlike grit or bead blasting, a MicroBlasting system can only cycle abrasive

What does the form factor (grain shape) indicate?

The description of the grain shape can range from “angular” to “acicular” to “spherical”. When the value of the dimensionless form factor is 1, the grain is spherical. The smaller the form factor, the pointier the grain.

What are the main components used in the construction of bonded abrasives?

Abrasive grains – usually aluminum oxide or silicon carbide Bonding agent – usually a resin bond Spacing of grains within the bond – determine porosity and strength

Which measurement methods are applied?

Dynamic image analysis (DIA) Static light scattering (SLS, also called laser diffraction) Screen analysis Impedance method Sedimentation

How about your delivery time?

Generally, it will take 30 to 60 days after receiving your advance payment. The specific delivery time depends .on the items and the quantity of your order.

What is the difference between aluminium oxide and white fused alumina?

Al2O3 alumina is the starting material of aluminium production, both of metallic aluminium and aluminium oxide. It is porous an has a large reactive surface.

How do i know what abrasive is best for my application?

An abrasive’s shape, hardness, and particle size really determine the effectiveness of a MicroBlasting application. Each application is unique, and abrasive selection depends on the composition of the targeted part and the application’s desired result. See our Abrasive Media

How is silicon carbide obtained?

Silicon carbide (SiC) is produced from coke and quartz sand applying the Acheson process in an electric resistance furnace. When petrol coke and quartz sand are grouped around a graphite electrode and heated to a temperature of 2,000°C,

What is grit size?

Grit size typically runs from coarse (16 -24 grit), medium (36 – 60 grit) and fine (80-120 grit). Superfine grits run from 150 and higher. Grinding wheels usually will be between 24 and 100 grit. Honing stones and
