Warfarin is a coumarin anticoagulant, which has anti-vitamin K effect in vivo. It can inhibit the synthesis of coagulation factors II, VII, IX and VII in the liver which are participated by vitamin K. There was no resistance to coagulation factors II, _, _and_in blood. Therefore, it can not be used as an in vitro anticoagulant. In vivo anticoagulant also needs active coagulation factor consumption before it can be effective, and its effect and maintenance time are longer. It is mainly used to prevent and treat thromboembolic diseases. Warfarin silicone bracelet is Perfect provider of information in a medical emergency. bracelet-maker-rubberupcycle-silicone-bracelets old is needed for debossed, embossed, colorfilled styles. We make a mold and set it in the machine, the high temperature of about 200℃ will solidify rubber into the sharp of bracelet. let"s see how the mould come into being. Mold, industrial production to use injection, blow molding, extrusion, die-casting or forging and forming, smelting, stamping and other methods to get the various models and tools of the required products. In short, mold is used to make molding tools. This tool is made up of various parts, and different molds are made up of different parts. It mainly realizes the processing of the shape of the articles by changing the physical state of the formed material. It has the title of "the mother of industry". Under the action of external force, the billet becomes a tool with specific shape and size. It is widely used in blanking, die forging, cold heading, extrusion, compaction of powder metallurgy parts, pressure casting, and plastic or injection molding of engineering plastics, rubber, ceramics and other products. The mold has a specific contour or inner cavity shape, and the shape of the cutting edge can be used to separate the blank from the contour line (blanking). The shape of the inner cavity can be used to obtain the corresponding three-dimensional shape of the blarubber wrist bandsnk. The mold generally consists of two parts, the movable die and the fixed die (or punch and concavrubber wrist bandse die), and the two parts can be divided into two parts. When separate parts are removed, the blank is injected into the mold cavity to form. The mold is a precision tool with complex shape, bearing the bulging force of the billet. It has high requirements for the structure strength, stiffness, surface hardness, surface roughness and machining precision. The development level of die production is one of the important symbols of the mechanical manufacturing level.
