A gloss meter is a device which is used to measure specific reflection.
Are gloss meters important in manufacturing?
It is in the best interest of a car manufacturer to use a gloss meter so that their products have gloss levels which are guaranteed to be appealing to prospective car buyers. The meter is used to determine gloss levels of different auto mobiles’ parts including the steering wheel, chrome fittings, paint for the bodywork panels, plastic interior finishes, and others. They are used in various stages of manufacturing to ascertain whether the components are above par. Also, they are utilized when the different components come together as a finished car to make sure that the car appears homogeneous.
Who use gloss meters?
Companies in the manufacture of paints and coatings also use gloss meters in various stages. The entire formulation-manufacture-application process is dotted with evaluations with gloss meters. Only by doing so, can the company be sure that there are fewer products which do not pass quality control at the end of the manufacturing process.
Companies processing natural stone come up with products with a variety of finishes. Some stones are left textured and matt in appearance. Others, like marble, have a smoothed polished look and great sheen. Gloss meters are highly useful to determine and achieve the gloss level that one needs.
The printing business also need gloss meters. Glossy magazine covers and advertisement pages, company brochures, promotion and deluxe packaging materials all need to be UV varnished and laminated to achieve a chic, sophisticated texture and look.
What are gloss meters used for?
You can paint, coat, varnish, or stain furniture in levels ranging from ultra matt to the strongest gloss. Gloss meters are used to make sure that products belonging to one batch are consistently glossed. They are also employed to check that application and drying of the coating is done according to standards.
Components and products made of metal go through plating, finishing, and polishing to enhance their appeal, as well as to protect them from being corroded or from wearing out before their time. Gloss meters are used to control quality.
Heroin is a highly addictive drug which is a member of the opiate family. It interacts with the central nervous system which means that individuals who abuse this drug put themselves at risk for significant immediate and long-term harm including heroin addiction.
Symptoms of heroin addiction
When you abuse heroin, you can quickly develop a tolerance which means that you will need to take increasingly greater amounts of the drug in order to experience the desired effects.
Behavioral symptoms of heroin addiction:
Being frequently absent from work or education
Wearing long-sleeved shirts even in warm weather to hide marks
Lying about your whereabouts
Loss of interest in activities that were previously important to you
Physical symptoms of heroin addiction:
Noticeable unintentional weight loss
Watery eyes as well as a runny nose
Mental symptoms of heroin addiction:
Feelings including shame and guilt
Hopelessness and despair
Social symptoms of heroin:
Withdrawal from family and friends
Job loss and unemployment
Where can I get help for heroin addiction?
Specialist heroin addiction treatment programmes at rehabilitation centres will usually begin with a medically assisted withdrawal detoxification. You will firstly be asked a range of questions to tailor your treatment. These may include:
How much heroin you take
Whether you are abusing any other drugs
How your physical and mental health is
What your personal circumstances are
Whether you have had treatment for drugs before
Please be prepared that you may be asked for a urine sample. This will be tested to confirm that you are abusing heroin.
Once you then have completed this first step, you will be assigned a key worker who will help you put together a personalised treatment plan to help your heroin addiction. You’ll meet your key worker regularly throughout your treatment.
A resistor is an electrical component that works on a passive two terminal system. The role of a resistor is to limit or restrict the flow of an electrical current into a circuit. Resistors can also be used to adjust signal levels, terminate transmission lines and divide voltages.
There are three main types of resistors; fixed, special and variable resistors. Fixed resistors are the most commonly used type of resistor and have three vital uses. Their first use is protecting other components from high currents that could damage them. Another use is to control time delays by working with a capacitator to control this. Finally, fixed resistors can also divide voltage into different parts of a circuit.
A special resistor is a component with a particular use. For example, light-dependent resistors use a photo-sensitive plates to detect light changes and therefore change the resistance levels dependent on this. Another type of special resistor is a thermistor, which are used in temperature sensing circuits. Thermistors contain negative temperature coefficients that increase the temperature as resistance falls.
A variable resistor comes in two forms; a resistor and a potentiometer. A variable resistor alters continually as it works whereas potentiometers control and fix resistance once adjusted. A way to distinguish the two of these is by their size. Potentiometers are usually smaller than resistors which tend to have a long spindle attached to an operating knob.
What are Ohms?
To measure the ability of a components resistance of an electrical flow we use ohms. Ohms are the unit of resistance. We use the letter ‘R’ to symbolise an ohm. The way we set this out is placing the ’R’ after a number which symbolises that the number is more than one i.e. 2R is equal to 2 Ohms. To symbolise a number is less than one we place it after the ‘R’ i.e. 2R5 is equal to 2.5 Ohms and R25 is equal to 0.25 Ohms.
What are Resistance Values?
All resistance values are symbolised in a series of colours. Each colour stands for a different unit which aids in distinguishing what units the resister holds when marked on the component.
There are four bands in total. The first band indicates tens and the second band is the units. The band colours represent difference units from 0 to 9, for example orange is 3 and blue is 6. So, a sequence of orange and blue would represent 38.
The third band is what you multiply the result of the first two bands by. The colour here also represents units e.g. silver equals 0.01 and red is 100. So here if the third band was red then the resistance would be 3.8 kilo-ohms.
Finally, the forth band shows the tolerance of the resistor. Resistor manufacturers can not totally guarantee that the first 3 bands on the component are the current resistance level. Therefore, the tolerance band gives a percentage of which the resistance can be higher or lower. A red band indicates a 2 % tolerance, a gold is 5 % and a silver is a 10 % tolerance. For example, a band with a resistance of 100 ohms and a tolerance of 5 % would have a resistance level between 95 and 105 ohms.
