How to Identify the quality of microfiber leather

1. Check the surface grains. The texture of high quality microfiber is more clear and the surface layer feels really like genuine leather. However, the poor quality microfiber leather texture is rough and with strong sense of plastics.

2. Handfeeling. High quality…[Leggi tutto]

Although auxiliaries have been a key component of immersion dyeing processes for many years the precise mode of action of many auxiliaries has not been fully resolved. This part of the paper discusses the various types of auxiliary available and the nature of the assistance they provide in immersion dyeing processes, together with both…[Leggi tutto]

 At present, DC brushless blowers mostly use brushless DC motors, which greatly simplify the structure of brushless DC motors by eliminating the collector ring and brushes for excitation. It not only improves the technical performance of the motor, but also greatly improves the mechanical reliability and life of the motor. Not only that, it…[Leggi tutto]

Mini excavators are one of the quickest growing equipment types, with the machine’s popularity seemingly ever-increasing. According to data from Off-Highway Research, global sales for the mini excavator were at their highest point ever last year, at over 300,000 units.

Injection molding machines perform a wide range of mechanical movements with differing characteristics. Mold opening is a low-force high-speed movement, and mold closing a high-force low-speed movement. Plasticizing involves high torque and low rotational speed, while injection requires high force and medium speed. A source of motive power…[Leggi tutto]

Adding carbon black (CB) particles to elastomeric polymers is essential to the successful industrial use of rubber in many applications, and the mechanical reinforcing effect of CB in rubber has been studied for nearly 100 years. Despite these many decades of investigations, the origin of stiffness enhancement of elastomers from incorporating…[Leggi tutto]

Emulsifiers

Brent Murray, professor of food colloids at the University of Leeds, believes understanding ice cream chemistry begins with realising that it’s an emulsion and a foam mixed together. ‘Your basic ice cream mix is just milk, cream, sugar and flavourings, which gets homogenised to form an emulsion of fat droplets in water, whi…[Leggi tutto]

Earlier this year I published a three-part article series titled “What to do with all this plastic?” (Part One, Part Two, and Part Three), which looked at the global problem with plastics accumulating in different areas around the world and innovative concepts communities have adopted to help deal with the abundance of plastic products and…[Leggi tutto]

A large part of enjoying wine lies in savoring its aroma. The wine glass has to gather the wine’s aroma so you can savor it when you drink.

If you use a regular mug and fill it to the brim, all the characteristic vapors of the wine will be gone by the time you start to sip.

But, there’s more to it than just enj…[Leggi tutto]

What is PVC (PolyVinyl Chloride)?

If your car is equipped with disc brakes, brake calipers are critical to slowing and stopping your car. Here’s what you need to know.

The brake caliper plays a central role in a disc-brake system and has two functions. First, it acts either as a bracket to support the brake pads on either side of the rotor or to support the caliper…[Leggi tutto]

Wound Dressings

Wound, whether it is a minor cut or a major incision, it is important to care for it properly, part of this process includes wound dressing. Dressing is designed to be in contact with the wound, which is different from a bandage that holds the dressing in place. Historically, wet-to-dry dressings have been used…[Leggi tutto]
