נייר פיר גדול מעיסת ממוחזר מתייחס לנייר פיר גדול המיוצר מפסולת נייר. ביצועי הזיהוי העיקריים שלו הם כדלקמן:

תכונות חוזק ומתיחה: כדי להבטיח שזה לא קל להיסדק או לעוות במהלך השימוש. ניתן להעריך את תכונות החוזק והמתיחה על ידי שיטות בדיקה כגון בדיקת מתיחה ובדיקת קריעה.

שטוחות פני השטח: להבטיח שלא יהיה פיגור נייר או אי יציבות איכותית בתהליך ההדפסה, ציפוי וכן הלאה. Its surface flatness can be evaluated by surface flatness test.

Absorbency: In order to absorb ink or paint in printing, coating and other processes. Its water absorption performance can be evaluated by water absorption test.

Break resistance: to ensure that it is not easy to break or damage during transportation and use. The breakage resistance can be evaluated by the breakage resistance test.

שיטת זיהוי
It is necessary to adopt corresponding test methods and standards according to different performance indexes for the detection of large shaft paper of recycled pulp. The following are some common testing methods for the performance of large shaft paper of recycled pulp:

תכונות חוזק ומתיחה: Testing methods such as tensile tests and tear tests can be used to evaluate their strength and tensile properties. Tensile test generally uses a multi-functional testing machine, with longitudinal and transverse as the main test direction for testing. The tearing test evaluates the strength of the paper by measuring the tearing force under certain conditions.

שטוחות פני השטח: Its surface flatness can be assessed using a surface flatness tester, which evaluates its surface flatness by measuring the unflatness index of the surface of the paper.

Water absorption: A water absorption tester can be used to evaluate its water absorption performance, which measures the amount of water absorbed by the paper to evaluate its water absorption performance.

Breakage resistance: A breakage resistance tester can be used to evaluate its breakage resistance, which evaluates the breakage resistance of the paper by measuring the breakage force under certain conditions.

Gloss: Gloss can be assessed using a gloss tester, which measures the intensity of light reflected from a paper to assess its gloss.

שמירה על איכות סביבה: its environmental protection performance can be evaluated by detection means of heavy metals and harmful substances, such as X-ray fluorescence spectrometer, inductively coupled plasma mass spectrometer and other instruments to detect samples.

Bonding properties: The bonding properties can be evaluated by a peel strength tester, which measures the bonding strength between the paper and the bonding material.

Degradability: Methods such as soil burial test can be used to evaluate the degradability of the paper, which is evaluated by burying the paper in the soil and measuring the degradation rate and quality change.

Paper thickness: Instruments such as hand feel thickness meter and electronic thickness meter can be used to measure paper thickness for evaluation.

Paper moisture content: A paper moisture content tester can be used to measure the moisture content of the paper for evaluation.

הערות
In the detection of large shaft paper of recycled pulp, the following points should also be paid attention to:

Selection of samples: It is necessary to randomly select samples from well-representative batches for testing, and pay attention to the preservation and handling of samples to avoid affecting the test results.

Control of test conditions: it is necessary to strictly control the test conditions, כולל טמפרטורה, לחות, light and other factors, to avoid the influence of these factors on the test results.

Calibration of test equipment: It is necessary to calibrate test equipment regularly to ensure its accuracy and reliability.

Processing and analysis of data: statistics and analysis of test data are required to determine its scope of conformity and evaluate its product quality.

בקצרה, the detection of recycled pulp large-shaft paper needs to select the corresponding test methods and standards according to different performance indicators, and carry out under strict experimental conditions to ensure product quality and safety.
