Primary USES to meet low enough light inspection, inspection, strabismus inspection and hand inspection, etc. Request paper smooth and clean, are not allowed to have a passbook. 2. Physical properties of the inspection before the commencement of physical properties of the inspection work, must be based on norms to constant temperature and humidity pretreatment of paper, because different paper required for the test items, here is listed the first two: ( 1) White board paper good general requirements whiteboard paper texture, smooth surface, thickness, paper not fluff, good absorbency, and slip rate is small, and can be used to the requirement of multi-color overprint. To custom box making requirements, stiffness big, white board paper should have folding degree of good characteristics. First importing countries are: South Korea, Indonesia, the United States, Japan, etc. , especially in the quality of Japanese white board paper is preferred. The test items include: quantitative, thickness, whiteness, smoothness, breaking length, burst, folding, sizing degree, and the stiffness of the IGT, etc. ( 2) Corrugated base paper, corrugated base paper is one of an important material of production of corrugated board. Corrugated base paper for fiber bonding strength is good, smooth paper, good tightness and stiffness, requires a degree of elasticity that made to ensure that the cartons with shock and compression capacity. Target to be manipulated in addition to water, water is too small, paper brittle, corrugated processing attacks when they break; Paper moisture content is too large, soft, can bring difficulties to processing and molding. Generally the moisture content of paper should be control at 10% advisable. Domestic corrugated base paper can be divided into A, B, C, D four grades. Attempt to detect is quantitative, thickness, tightness, burst, ring crush strength, horizontal ring crush index, flat crush strength, breaking length, degree of sizing, moisture etc. Manifested by all kinds of target specification to assess the performance of the product quality, believe that these common sense about the practitioners still have a lot of help.
