Ang Kraft paper ay isang karaniwang materyal na pang industriya na papel, dahil sa mataas na lakas at wear resistance nito, so it is widely used in the production of packing cases, bags, book covers, handbags and other fields.

Pagganap ng pagtuklas
It needs to detect the following major performances:

Lakas ng loob: kraft paper needs to have high strength to ensure that it is not easy to be damaged or broken in the process of making packing cases, bags and so on. Lakas detection ay maaaring isagawa sa pamamagitan ng pagsukat ng lakas ng makunat, lakas ng flexural, compressive lakas at iba pang mga tagapagpahiwatig ng papel.

Paglaban sa pagsusuot: kraft paper needs to have high wear resistance to ensure that it is not easy to damage or wear in the process of making book covers, handbags and so on. Ang pagtuklas ng paglaban sa pagsusuot ay maaaring isagawa sa pamamagitan ng pagsukat ng koepisyent ng alitan ng ibabaw ng papel, magsuot ng paglaban at iba pang mga tagapagpahiwatig.

Air permeability: kraft paper needs to have a certain air permeability, so that the quality of packaging goods and shelf life. The detection of air permeability can be carried out by measuring the permeability, porosity and permeability coefficient of the paper.

Water absorption: kraft paper needs to have a certain water absorption, so as to play a certain buffering role in the production process. The detection of water absorption can be carried out by measuring the moisture content, water absorption speed and water absorption of the paper.

Pangangalaga sa kapaligiran: kraft paper needs to meet environmental protection standards, ay hindi naglalaman ng mga mapanganib na sangkap, walang polusyon sa kapaligiran. Ang pagtuklas ng proteksyon sa kapaligiran ay maaaring isagawa sa pamamagitan ng pagsukat ng mga volatile organic compounds, mga mabibigat na metal, klorido ions at floresan pagpapaputi ahente ng papel.

Kraft papel ay kailangang subukan ang mga katangian at mga pamamaraan ng pagsubok

Saklaw ng aplikasyon: Kraft paper has a wide range of applications, involving the production of packing boxes, bags, book covers, handbags and other fields, which need to be tested and evaluated according to specific application requirements. Ang pagtuklas ng saklaw ng aplikasyon ay maaaring isagawa sa pamamagitan ng pagsukat ng naaangkop na kapaligiran ng papel, the applicable product type and the applicable processing technology.

Packaging performance: The packaging performance of kraft paper is one of its important performance indicators, including packaging tightness, dimensional stability and stacking stability. The inspection of packaging performance can be carried out by measuring the thickness, toughness and surface flatness of the wrapping paper.

Appearance quality: because kraft paper is usually used for products with high appearance requirements, ang kalidad ng hitsura nito ay isa ring napakahalagang index, which needs to be tested for appearance, tulad ng surface flatness, ibabaw gloss, ibabaw ng pagkamakinis, surface defect-free and other indicators.

These performance indicators are the key content of kraft paper detection, iba't ibang mga kinakailangan sa paggamit at pamantayan ay makakaapekto rin sa mga pamantayan sa pagtuklas at pamamaraan ng papel.
