Compared with other gates, the main advantages of the three-roll gate are: low cost, high reliability and durability. When choosing a three-roller gate, you need to pay attention to the following indicators:
1. Reliability: The reliability of the gate is based on the reliability and integration of various components of the gate. The selection of good quality components is the basis, such as card readers, controllers, displays, etc.; the integration method mainly depends on the design and selection of the control unit and the communication method. The presence or absence of lightning protection components is also related to the reliability of the equipment.
2, rotating life: the gate is a constantly moving mechanism, mechanical wear and component fatigue is inevitable, mechanical rotation life is a key indicator. It can be judged from the action mechanism and material selection. Of course, there are formal institutional test reports that are better;
3, chassis material: the gate for people to use, a variety of external forces frequently, mechanical strength is an important consideration; the long-term operation of the gate, is a "portal", should be beautiful, so the choice of 1.5-2.0mm stainless steel is necessary . Stainless steel is divided into a variety of models, so use 304 stainless steel.
4, the movement principle: the three-rod movement is the main components of the gate, mechanical and electric can be used by international companies. In performance, the main focus is on mechanical life, pressure on the crossbar, running noise, thrust (feel), self-balancing, easy replacement of components, etc.;
5, the glass material above the bar code reader: the bar code reader must be transparent above, the cost of plexiglass is low, easy to process and install, but after repeated brushing, the glass will wear rough, affecting the reading speed and accuracy of the bar code Therefore, wear-resistant quartz glass must be used;
6, the speed of ticket inspection: the large flow of the gate, the speed of ticket inspection is a very important indicator. The ticket inspection speed depends on the control mode of the gate, the communication networking method, the ticket processing software, and the mechanical movement speed. Generally, the gate response speed is within 500ms.
7. Environmental requirements: In outdoor open air, the requirements for humidity and temperature are very high. A gate with complicated electronic circuit design is difficult to apply in an outdoor open environment. The housing of the gate can be designed to be rain-proof, but wet condensation and high temperatures are unavoidable, so it is important to use moisture- and high-temperature parts. It is wise to choose a gate that has an open-air application experience.
1, Used as W/O or O/W type emulsifying agent, Defoamer, oil emulsifier, PVC granules additives, etc., also can be used as laundry detergent.
2, Used be used as acrylic dyed before and after dyeing detergent components, and as a cationic dye, leveling agent, can be in the general industrial as emulsifier.
3, It is widely used in industries as dispersant, solubilizing agent, penetrating agent, emulsifier, wetting agent, detergent, etc
