When the dishes are bought for home, everyone wants to clean them as much as possible. What kind of water wash plays a decisive role. Experts told reporters that the cleaning methods for meat and fruits and vegetables should be separated. "Cleaning meat is of course using cold water," said Zhang Liang, a senior national cookery chef with many years of cooking experience and chief technician of Shandong Province. Especially now, the weather is getting colder and colder, and cold people like to wash meat with warm water. Some people think that meat is easily stained with dirt. In order to enhance decontamination, it also takes hot water for a while and then wash it. In fact, whether it is thawed frozen meat or fresh meat that has just been bought back, no warm water, especially hot water, can be used. Because washing meat with warm water or even hot water will accelerate the loss of protein and B vitamins in the meat, some amino acids will also be lost. "On the one hand, meat that has been treated with hot water can easily be spoiled and corrupted. On the other hand, the meat's taste can be affected and it will not be meaty."
It is particularly worth reminding that some people like to buy ready-made meat. Do you want to wash this kind of meat? better not. Meat is generally used to stir-fried meat or knead balls. After washing, it is not only fragrant, nutrient loss, but also become loose and do not become meatballs. If you want to eat meat, it's best to buy it yourself and wash it first. Or supervise the merchant to wash it later.
It is better to use warm water when washing all kinds of fruits and vegetables. He Hongju, a researcher at the National Vegetable Engineering Technology Research Center, points out that warm water can remove pesticide residues on fruits and vegetables more easily than cool water. Because organic phosphorus in pesticide residues is easily soluble in water, it will accelerate dissolution when the water temperature increases. At the same time, carbamate insecticides in pesticides also accelerate decomposition as the temperature increases.
Some people may worry that the nutrients in fruits and vegetables are very delicate. Will using hot water destroy the nutrition? In fact, the key is to control the water temperature to 40 degrees Celsius or so is appropriate. Otherwise, B vitamins, vitamin C, and some niacin and minerals in fruits and vegetables will be lost when the vegetables are washed. The method of controlling the water temperature is also very simple: 40 degrees Celsius water, try by hand should be warm and not hot.
2.0mm (0.079") Pitch Pin Headers
2.0mm pin headers are board-to-board or PCB to PCB Connectors rated for 250VAC and an industry-leading current of 3.0A. Antenk offers numerous configurations for this Pin Header . Designed for low-profile applications, this pin header is made from high-temperature thermoplastic and is offered with several means of connections and mounting styles such as through-hole (THM) or surface mount (SMT) and can be in vertical (straight), elevated or at a right angle configuration/orientation
Pin header customization is also available upon your request. The 2.0mm pitch pin header is highly recommendable for signal and low power PC board connections when space is at a premium and when 1.0mm and 1.27mm pitch headers cannot dissipate the required current. In addition, the 2.0mm pitch pin header holds an excellent mating quality that fits with various types of female connectors.
Automotive, Heavy Duty Military and Marine
2.0mm pitch pin headers are for not only suitable for densely packed equipment requiring weight reduction and downsizing but also for automotive connections, built to be robust in tough and harsh conditions.
Battery Connections
Rechargeable battery packs, battery balancers, battery eliminator circuits. Battery connections rely on the ability of the current to pass reliable and solid current. This prevents overheating in the circuit and voltage drop.
Medical Diagnostic and Monitoring equipment
Communications: Telecoms and Datacoms
Industrial and Automotive Control and Test
2.0mm pitch pin (male) headers are offered in either Surface-mount or Through-hole mount termination. At one side of this pin header is a series of pins which can either be mounted and soldered directly onto the surface of the PCB (SMT) or placed into drilled holes on the PCB (THM).
Best used for high-reliability products that require stronger connections between layers.
Aerospace and military products are most likely to require this type of mounting as these products experience extreme accelerations, collisions, or high temperatures.
Useful in test and prototyping applications that sometimes require manual adjustments and replacements.
2.0mm vertical single row header, 2.0mm vertical dual row header, 2.0mm Elevated single row pin header, 2.0mm Elevated dual row pin Header, 2.0mm Right-angle single row header and 2.0mm Right-angle dual row header are some examples of Antenk products with through-hole mount type.
Surface-Mount
The most common electronic hardware requirements are SMT.
Essential in PCB design and manufacturing, having improved the quality and performance of PCBs overall.
Cost of processing and handling is reduced.
SMT components can be mounted on both side of the board.
Ability to fit a high number of small components on a PCB has allowed for much denser, higher performing, and smaller PCBs.
2.0mm Right-angle Dual Row pin header, 2.0mm SMT Single row pin header, 2.0mm SMT Dual row pin header and 2.0mm Elevated Dual Row Pin Header are Antenk`s SMT pin headers.
Soldering SMT pin connectors can be done at a maximum peak temperature of 260°C for maximum 60 seconds.
2.0mm pitch headers may be further classified into pin orientation as well, such as vertical or straight Male Header or right-angle male header.
Vertical or Straight Pin (Male) Header Orientation
One side of the series of pins is connected to PCB board in which the pins can be at a right-angle to the PCB surface (usually called "straight" or [vertical") or.
Right-Angle Pin (Male) Header Orientation
Parallel to the board's surface (referred to as "right-angle" pins).Each of these pin-types have different applications that fit with their specific configuration.
Pcb Connector Stacking
Elevated Pin Header Orientation
Elevated pins aka Stacked Pins or Mezzanine are simply stacked pin headers providing an exact distance requirement between PCBs that optimizes electrical reliability and performance between PCB boards.
Profile Above PCB
This type of configuration is the most common way of connecting board-to-board by a connector. First, the stacking height is calculated from one board to another and measured from the printed circuit board face to its highest insulator point above the PCB.
Single, Dual, Triple and Four Row Number of Rows
For a 2.0mm straight or vertical Male Pin Header, the standard number of rows that Antenk offers ranges from 1 to 4 rows. However, customization can be available if n number of rows is needed by the customer. Also, the number of contacts for the single row is about 2-40 pins. For dual row, the number contacts may vary from 2-80 pins. For triple row, it`s 2-120 pins, while for four-row, it`s 2-160 pins.
Pin Material
The pins of the connector have been designed with copper alloy. With customer`s demand the pins can be made gold plated.
Breakaway design
The pin headers are also equipped with a breakaway design making them fully compatible with their female receptacles.
Custom 2.0mm Pitch Pin Headers
Customizable 2.0 mm pitch pin headers are also available, making your manufacturing process way faster as the pins are already inserted in the headers, insulator height is made at the right size and the accurate pin length you require is followed.
Parts are made using semi-automated manufacturing processes that ensure both precision and delicacy in handling the headers before packaging on tape and reel.
Tape and Reel Packaging for SMT Components
Antenk's SMT headers are offered with customizable mating pin lengths, in which each series has multiple number of of circuits, summing up to a thousand individual part number combinations per connector series.
The tape and reel carrier strip ensures that the headers are packaged within accurately sized cavities for its height, width and depth, securing the headers from the environment and maintaining consistent position during transportation.
Antenk also offer a range of custom Tape and reel carrier strip packaging cavities.
