Bevel gears are like the chameleons of the gear world, capable of changing the axis of rotation in diverse ways! Here's a breakdown of these versatile components: What are bevel gears? They are cone-shaped gears that transmit power between intersecting shafts. These shafts can be at various angles, with 90 degrees being the most common. Their teeth also follow the conical shape, angling towards the apex of the cone, allowing them to mesh smoothly. Types of bevel gears: Straight bevel gears: The simplest type, with teeth pointing directly to the cone's apex. Spiral bevel gears: Similar to straight, but teeth curve back on themselves for smoother operation and reduced noise. Hypoid gears: Special bevel gears with shafts offset, allowing for higher gear ratios and greater moment capacity. Crown gears: Bevel gears with 90-degree angles where teeth resemble crown points, often used in car differentials. Key features: Change rotation axis: Unlike spur gears with parallel shafts, bevel gears change the direction of rotation, often by 90 degrees. Varying angles: Can work at different angles, not just 90 degrees, though that's most common. Gear ratios: Typically transmit power at a 1:1 ratio, but can be designed for other ratios too. Applications: Abundant in machinery like car differentials, hand drills, angle grinders, and even clocks. Additional points: Bevel gears can be made from various materials like steel, plastic, and nylon, depending on the application. They come in different sizes and tooth profiles to suit diverse needs. Understanding bevel gears is crucial for anyone working with machinery that involves changing rotation axes.

PMDETA catalyst is a highly active, pure liquid tertiary amine that is suitable for use as a blowing catalyst in a number of rigid and flexible polyurethane foam applications. ADVANTAGES: In model systems, PMDETA catalyst has proven to have catalytic activity equivalent to other established blowing catalysts for the urea reaction. However, PMDETA catalyst has a greater affect than established blowing catalysts on the urethane or gelling reaction. PMDETA catalyst is very effective in pour-inplace polyurethane systems (such as rigid appliance systems), which are based on MDI. At a use level of 1.5 php, PMDETA catalyst provides the necessary flowability and cure rates required in the production environment. PMDETA catalyst is also recommended for TDI, TDI/MDI and MDI HR flexible molded foams, as well as for use in integral skin and microcellular systems. It can also be as a raw material to make quaternary ammonium salt.

It should be stored separately from oxidizers, reducing agents, acids, alkalis, combustibles, and edible chemicals, and avoid mixed storage. Use explosion-proof lighting and ventilation facilities. It is forbidden to use mechanical equipment and tools that are prone to sparks. The storage area should be equipped with leakage emergency treatment equipment and suitable storage materials. Application The main purpose of acetonitrile is as a solvent. For example, as a solvent for extracting butadiene, a solvent for synthetic fibers and a solvent for some special coatings. Used in the petroleum industry to remove tar, phenol and other solvents from petroleum hydrocarbons. In the oil industry, it is used as a solvent for extracting fatty acids from animal and vegetable oils, and as a reaction medium for the recrystallization of steroid drugs in medicine. When a polar solvent with a high dielectric constant is required, a binary azeotropic mixture of acetonitrile and water is often used. Acetonitrile is an intermediate of medicine (vitamin B1) and spices, and a raw material for the manufacture of s-triazine nitrogen fertilizer synergist. It is also used as a denaturant for alcohol. In addition, it can also be used to synthesize ethylamine, acetic acid, etc., and also have many uses in textile dyeing and electronics industry. Acetonitrile is also used as a mobile phase solvent in analytical equipment such as chromatography.
Product Description Paraffin wax, also called 'paraffin', is a white, tasteless, odourless, translucent waxy solid. Paraffin wax is a type of wax that is derived from petroleum. Here are some key facts about paraffin wax: 1. Composition: Paraffin wax is primarily composed of long-chain hydrocarbons, specifically alkanes. These hydrocarbons are saturated, meaning they contain only single bonds between carbon atoms. 2. Physical Properties: Paraffin wax has a relatively low melting point, typically between 46°C to 68°C (115°F to 154°F), making it easy to melt and work with. It solidifies at room temperature.  Popular Products Our paraffin wax are kunlun brand from Petrochina (Fushun Petrochemical Company and Daqing Petrochemical Company).Mainly Products are fully refined paraffin wax, semi refined paraffin wax and crude paraffin wax with the melting point of 54/56/58/60/62/64.      (1)Fully Refined Paraffin Wax 58/60             (2)Semi Refined Paraffin Wax 58/60             (3)Fully Refined Paraffin Wax 56/58       (4)Fully Refined Paraffin Wax 60/62          (5)Fully Refined Paraffin Wax 64/66                (6)Crude Paraffin Wax 58/60   Product Parameters  Item Value Test method Grade #52 #54 #56 #58 #60 #62 #64 #66 Melting point, °C 52 54 56 58 60 62 64 66 GB/T 2539 54 56 58 60 62 64 66 68 Oil content, %(mass) 0.5 GB/T 3554 Color, Saybolt scale +27 +25 GB/T 3555 Max light stability 4 5 SH/T 0404 Penetration, (25°C),1/10mm 19 17 GB/T 4985 Kinematic viscosity, (100°C),m/s Report GB/T 265 Odor number 1 SH/T 0414 Water soluble acid/base Not detected SH/T 0407 Mechanical impurity & moisture Not detected Visual inspec

Plano Concave Lens A plano-concave lens is an optical lens with one concave and one flat surface. It has a negative focal length and can be used for light projection, beam expansion or to increase the focal length of an optical system. Plano concave lens bend parallel input rays so they diverge from one another on the output side of the lens and hence have a negative focal length. The spherical aberration of the plano concave lenses is negative and can be used to balance aberrations created by other lenses. Similar to the plano concave lens, the curvature surface usually faces the largest object distance or the infinite conjugate to minimize spherical aberration. Applications 1. Plano-concave lenses are commonly used to divert parallel beams in instruments such as Galilean beam expanders or telescopes. 2. Plano-concave lenses are also used for beam expansion of high peak power pulsed lasers. The incident beam will be focused on a concave surface to a point outside the instrument.
