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, pencetakan, making folders and other fields.

Kinerja deteksi
The performance test of double grey paper usually includes the following aspects:

Detection of base weight: The base weight per square meter is calculated by weighing the weight of a double-grey paper sample of a certain size. Timbangan atau timbangan elektronik presisi biasanya digunakan untuk menimbang.

Deteksi ketebalan dan keseragaman: 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. Alat pengukur ketebalan manual biasanya menggunakan alat ukur ketebalan genggam, pengukur ketebalan otomatis biasanya menggunakan triangulasi laser untuk mengukur ketebalan, dan metode pendeteksian keseragaman dapat dilakukan dengan menggunakan sistem visi mesin.

Pengujian kekuatan: through the use of strength testing instruments, seperti mesin tarik elektronik, multi-functional testing machine, dll., to measure the double gray paper tensile strength, kekuatan tekan dan indikator lainnya.

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.

Pengujian kinerja pengemasan: melalui penggunaan instrumen pengujian kinerja pengemasan, seperti penguji kompresi bergelombang, penguji lentur bergelombang, penguji tumpukan, dll., to measure the compression strength, kekuatan lentur, stacking stability and other properties of the carton made of double grey paper.

Tes kemampuan cetak: By using printing quality test instruments, seperti penguji akurasi pencetakan, penguji kecepatan pencetakan, penguji adhesi tinta, dll., to measure the printing quality of double gray paper, kecepatan pencetakan dan daya rekat tinta serta properti lainnya.

Pengujian perlindungan lingkungan: by using environmental testing instruments, seperti penguji senyawa organik yang mudah menguap, penguji logam berat, penguji ion klorida, dll., untuk mengukur kandungan senyawa organik yang mudah menguap, logam berat, chloride ions and other harmful substances in double gray paper.

Tensile strength and elongation at break detection: 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.

Tes ketahanan air: through the use of water resistance tester to measure the water resistance of double grey paper.

Wear resistance test: 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. Timbangan atau timbangan elektronik presisi biasanya digunakan untuk menimbang.

Deteksi ketebalan dan keseragaman: Use manual or automatic thickness measuring instrument to measure the thickness of double gray paper, dan dengan pengukuran laser atau metode pengukuran mesin untuk mendeteksi keseragaman. Alat pengukur ketebalan manual biasanya menggunakan alat ukur ketebalan genggam, pengukur ketebalan otomatis biasanya menggunakan triangulasi laser untuk mengukur ketebalan, dan metode pendeteksian keseragaman dapat dilakukan dengan menggunakan sistem visi mesin.

Strength test: use double grey paper strength test instrument to measure its tensile strength, kekuatan tekan dan indikator lainnya. Biasanya menggunakan mesin tarik elektronik, mesin uji multi-fungsi, penguji kekuatan pecah dan peralatan lainnya untuk pengujian.

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, kekuatan lentur, 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.

Tes kemampuan cetak: Use printing quality test instrument to measure the printing quality of double gray paper, kecepatan pencetakan dan daya rekat tinta serta properti lainnya. Penguji presisi pencetakan dapat mengukur kualitas pencetakan, penguji kecepatan pencetakan dapat mengukur kecepatan pencetakan, dan penguji adhesi tinta dapat mengukur adhesi tinta dan kertas.

Pengujian perlindungan lingkungan: menggunakan instrumen pengujian lingkungan untuk mengukur kandungan senyawa organik yang mudah menguap, logam berat, chloride ions and other harmful substances in double gray paper.
