Comment fonctionne une fraiseuse à broches ? Comprendre les mécanismes du fraisage à broches
Pin milling (pin mill) is a versatile and efficient grinding method. It works by impact grinding. This happens using pins or hammers in a rotating chamber. Pin mill is a type of impact mill that utilizes multiple rows of intermeshing pins or studs to achieve particle size reduction by impacting the particles against the pins. […]
Comment utiliser le carbonate de calcium modifié dans les entreprises de fabrication de papier ?
At present, in the papermaking process, filler and pigment dosage has been second only to fiber, is the second most important raw material. Commonly used papermaking fillers are calcium carbonate, talc, kaolin, wollastonite, bentonite and so on. Papermaking has gradually shifted from acidic to neutral and alkaline processes. Modified calcium carbonate, as an important papermaking […]
Noir de carbone
A black powdery substance formed by the incomplete combustion or pyrolysis of hydrocarbons in the gas phase under strictly controlled process conditions. Its composition is mainly elemental carbon and contains a small amount of oxygen, hydrogen, and sulfur. Carbon black particles are nearly spherical, between 10 and 500μm. Many particles are fused or agglomerated into […]
Cire de polyéthylène | Cire PE
Polyethylene wax (PE wax), or polymer wax, is called polyethylene wax. It is widely used because of its excellent cold, heat, chemical, and abrasion resistance. In normal production, this part of the wax as an additive can be added directly to the polyolefin processing, which can increase the gloss and processing performance of the product. […]
Carbonate de calcium | CaCO₃
Calcium carbonate is an inorganic compound with the chemical formula CaCO₃ and is the main component of limestone, marble, etc. Calcium powder is usually white crystals, odorless, essentially insoluble in water, and reacts readily with acids to release carbon dioxide. It is one of the common substances found on earth within rocks such as aragonite, […]
