Articoli e attrezzature per test delle prestazioni in doppia carta grigia
Double grey paper is a kind of commonly used packaging paper. It is a composite board made of two layers of grey paper. It has high strength and rigidity, and is widely used in packaging, stampa, making folders and other fields.

Prestazioni di rilevamento
The performance test of double grey paper usually includes the following aspects:

Rilevamento del peso base: The base weight per square meter is calculated by weighing the weight of a double-grey paper sample of a certain size. Precision electronic scales or balances are usually used for weighing.

Rilevazione dello spessore e dell'uniformità: the thickness of double grey paper is measured by using manual or automatic thickness measuring instrument, and the uniformity is detected by laser measurement or machine measurement method. I misuratori di spessore manuali utilizzano solitamente strumenti di misurazione dello spessore portatili, gli spessimetri automatici solitamente utilizzano la triangolazione laser per misurare lo spessore, e il metodo per rilevare l'uniformità può essere eseguito utilizzando sistemi di visione artificiale.

Test di forza: attraverso l’uso di strumenti per prove di resistenza, come la macchina di trazione elettronica, macchina di prova multifunzionale, eccetera., to measure the double gray paper tensile strength, resistenza alla compressione e altri indicatori.

Corrugated detection: through the use of corrugated altimeter or corrugated pressure tester and other instruments to detect the corrugated height and strength of double grey paper.

Test delle prestazioni dell'imballaggio: through the use of packaging performance testing instruments, such as corrugated compression tester, corrugated bending tester, stacking tester, eccetera., to measure the compression strength, bending strength, stacking stability and other properties of the carton made of double grey paper.

Printability test: By using printing quality test instruments, such as printing accuracy tester, printing speed tester, ink adhesion tester, eccetera., to measure the printing quality of double gray paper, printing speed and ink adhesion and other properties.

Test di protezione ambientale: by using environmental testing instruments, come tester di composti organici volatili, tester per metalli pesanti, tester per ioni cloruro, eccetera., per misurare il contenuto di composti organici volatili, metalli pesanti, chloride ions and other harmful substances in double gray paper.

Resistenza alla trazione ed allungamento al rilevamento della rottura: by using a tensile testing machine to measure the double gray paper tensile strength and elongation at break.

The detection of moisture content: by using a moisture content tester to measure the moisture content in the double grey paper, in order to assess its quality.

Test of acidity and alkalinity: by using PH value tester or PH tester to test the acidity and alkalinity of double grey paper.

Prova di resistenza all'acqua: through the use of water resistance tester to measure the water resistance of double grey paper.

Prova di resistenza all'usura: by using the wear resistance tester to measure the wear resistance of the double grey paper.

Test of flexibility: By using a flexibility tester to measure the flexibility of double grey paper.

Testing methods and instruments
The specific detection methods and instruments of double grey paper are as follows:

Basic weight detection: Take a certain size of double grey paper sample, weigh its weight, calculate the basic weight per square meter. Precision electronic scales or balances are usually used for weighing.

Rilevazione dello spessore e dell'uniformità: Use manual or automatic thickness measuring instrument to measure the thickness of double gray paper, and by laser measurement or machine measurement method to detect uniformity. I misuratori di spessore manuali utilizzano solitamente strumenti di misurazione dello spessore portatili, gli spessimetri automatici solitamente utilizzano la triangolazione laser per misurare lo spessore, e il metodo per rilevare l'uniformità può essere eseguito utilizzando sistemi di visione artificiale.

Strength test: use double grey paper strength test instrument to measure its tensile strength, resistenza alla compressione e altri indicatori. Usually use electronic tensile machine, multi-function testing machine, rupture strength tester and other equipment for testing.

Corrugating test: use corrugating altimeter or corrugating pressure tester and other instruments to test the corrugating height and strength of double grey paper. These instruments usually use photoelectric sensors or laser sensors to measure.

Packaging performance test: Use packaging performance test instrument to measure the compression strength, bending strength, stacking stability and other properties of the carton made of double grey paper. Corrugated compression tester can measure the compression performance of corrugated cardboard, corrugated bending tester can measure the bending performance of corrugated cardboard, and the stacking tester can measure the stacking stability of corrugated boxes.

Printability test: Use printing quality test instrument to measure the printing quality of double gray paper, printing speed and ink adhesion and other properties. The printing precision tester can measure the printing quality, the printing speed tester can measure the printing speed, and the ink adhesion tester can measure the adhesion of ink and paper.

Test di protezione ambientale: use environmental testing instruments to measure the content of volatile organic compounds, metalli pesanti, chloride ions and other harmful substances in double gray paper.
