Measuring Principle
The internal stress plastic products has a birefringent characteristic. In other words, if there is stress inside of these types of products, light from he polarized lamp will be divided into different units, which produce optical interference phenomenon(ripple patterns) in turn.
Under white-light lamp, you can see aubergine ripples, which is caused by the presence of stress.
From the observation of colored patterns, you can see stress distribution directly, then evaluate and improve the annealing process.
The inspection of plastic molds is more complex as the colored patterns cased by stress is irregular. A similar situation may occur with glass products, which is called stress stretching. For example, a qualified mold will have a large amount of stress released by tension.
The role of full-wave plate :
The full-wave plate increases or decreases the full wavelength of a phase difference, thereby forming a colored pattern, which is easier to analyze.

The role of full-wave plate :
When testing glass samples without the full-wave plate, usually only black or gray shadow patterns can be seen. The full-wave plate increases or decreases the full wavelength of a phase difference, thereby forming a colored pattern, which is easier to analyze.

When it comes to anticoagulants, many people don't understand what they are used for. Simply put, anticoagulants are chemicals that prevent blood clotting. It is very commonly used in blood collection tubes used in hospitals to collect blood for testing. In different blood tests, the applicable anticoagulants are also different. Commonly used anticoagulants include EDTA, sodium citrate, heparin, etc. Let's take a look at the mechanism of action of these anticoagulants.
Because blood coagulation is divided into three main stages: first, prothrombin activator is formed; second, prothrombin activator catalyzes the conversion of prothrombin into thrombin; third, thrombin catalyzes the conversion of fibrinogen into fibrin . In these three stages, the participation of calcium ions is required, so once the chelated calcium ions are removed, the blood loses the necessary conditions for coagulation and cannot be coagulated.
1. EDTA (ethylenediaminetetraacetic acid)
There are three different forms of EDTA ethylenediaminetetraacetic acid anticoagulant, namely EDTA dipotassium, EDTA tripotassium, and EDTA disodium. Tripotassium EDTA is relatively easier to dissolve and is more popular than other forms. EDTA plays an anticoagulant effect mainly by chelating calcium ions and removing free calcium ions.
2. Sodium citrate
Sodium citrate combines with free calcium to form a sodium citrate complex, which consumes calcium to achieve anticoagulant effect. The recommended anticoagulant concentration is 3.2% or 3.8%. The ratio of anticoagulant to blood is 1:9 and 1:4. Blood after sodium citrate anticoagulation cannot be used for compressed cell volume (PCV), hemoglobin (Hb) estimation, total white blood cell count TLC, and differential white blood cell count (DLC) because citrate is used as a solution and it changes blood concentration.
3. Heparin
Heparin is an acid mucopolysaccharide with affinity for blood proteins and can be used as antithrombin and antithromboplastin. It prevents the conversion of prothrombin into thrombin, thereby playing an anticoagulant effect. As an anticoagulant, heparin is often used in emergency biochemistry and blood rheology testing.
