Biological Buffer Series are organic substances that maintain a constant pH over a given range by neutralizing the effects of hydrogen ions. Buffers also provide a pH environment conducive to critical biochemical processes, wherein a significant change in pH can lead to a harmful change in molecular structure, biological activity or functions. They keep the pH constant by taking up protons which are released during reactions, or by releasing protons when they are consumed by reactions.

Excavators, also known as excavating machinery, are earthmoving machinery that uses buckets to excavate materials above or below the bearing surface, and load them into transport vehicles or unload them to stockpiles.

The emulsifying machine is to shear, disperse and impact the material through the high-speed rotation of the homogenizer head connected to the engine. In this way, the material will become more delicate, and the oil and water will be melted. It is widely used in cosmetics, shower gels, sunscreens, and many other cream products that use emulsifying machines. Sauce, juice, etc. in the food industry. Ointments in the pharmaceutical industry. Emulsifiers are used in petrochemicals, paints and inks, etc.

Blow molding is a process that can be used to produce a wide array of plastic products that can be small, large, or even custom-shaped. Besides bottles, jerry cans, and drums, plastic floats are also a very popular application for this kind of process. Float blow molding machines are ac****ulator type, and they can produce floats that are later on used for different purposes.http://www.hongjiumould.com/float-mould/
