The Strain viewer ( Ref.PSV-202) has been designed to observe and analyze the internal stress of preform and other plastic products . Detecting object 1. Preform ( Color and colorless types ) 2. Other transparent plastic products Plastic molds , plastic bottle , cosmetic bottle , beverage bottle, plastic tray, plastic film ., etc Specifications Analyzer : diameter 100mm Viewing field: 200mm*200mm Measuring height :236mm Overall size: 310*285*350mm Voltage: 24VDC( with a AC/DC adaptor ) Light source: White fluorescent lamp Weight:8KG 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.
Function 1.Observe stress distribution in transparent plastic, glass products and optical crystals 2.Measure retardation caused by internal stress in glass and optical crystals Detecting object 1. transparent glass products with complex construction. such as : penicillin bottle, ampoule , mobile phone cover, light tube, light bulb,solar glass ,automobile glass,sapphire, glass container , glass handicraft 2. transparent plastic samples plastic bottle , cosmetic bottle , beverage bottle, contact lenses, plastic tray plastic film 3. optical crystals such as quartz , SiC, calcium fluoride Detecting methods Sensitive Color Method and Senarmont Method Specification Model PSV-413 Size W291 D384 H388mm Measuring range 0-280nm Weight 11Kg Viewing field W200 D200mm Measure height Max259mm Light Source Warm white LED light 10W Power DC 12V(with a AC/ DC adapter) Others: 1.Polarizing light field intensity : 120cd/m2 (10W LED lamp) 2.Polarization degree of the polarizing material: 99% 3.Polarization field: 200*200mm 4.Instrument structure: a 1/4 wave plate in the analyzer and a full-wave plate in the polarizer (wavelength 565nm). Slow axis of the plate is at 90 to the polarization plane .5.A dial on the Analyzer is used to measure the rotating angle (range: 0-180 )

Glazing glass is a combination of two or more pieces of glass spaced apart with a spacer bar and hermetically sealed with a primary and secondary sealant to form a single unit with one or more air spaces between each other. Max size :3300*12000mm Main character : Energy saving , improving the thermal performance Sound insulated Security and comfort Component : 1.� Glass items:� consists of hard or soft low E glass ,reflective glass ,clear glass ,tinted glass, with types of flat tempered ,bent ,laminated processing ,according to the application 2.� Spacer bar :is the material used to separate the two glass lites in an IGU. It can be made by aluminum,stainless steel,hybrid ,plastic material . The spacer width usually from 6mm-18mm.
It is processed by controlled thermal or chemical treatments to increase its strength compared with normal glass, about four times stronger than annealed, glass. When broken, tempered glass fractures into small, relatively harmless pieces, it is widen used for window, door, railing, furniture, vehicle.
JHG pattern glass is widely used in cabinets, windows and doors. and also we also can offer you finished products with cut, polished, tempered, laminated, acid etched. JHG pattern glass� is a kind of decorative translucent glass with embossed patterns on one or both surfaces. Pattern glass is generally used where privacy or obscurity is desired but light transmission is still important. With the special property of decoration, patterned glass can allow light to pass through, at the same time, it can also prevent clear view. Usually it transmits only slightly less light than clear glass.JHG pattern glass is widely used in cabinets, windows and doors .and also we also can offer you finished products with cut� ,� polished, tempered , laminated, acid etched .
