Ultralow quantitative thermal sensitive paper
Technical Field
The utility model relates to a papermaking technical field especially relates to an ultralow ration temperature-sensitive paper.
Background
The principle of the thermal paper is that a layer of thermal paint (thermal discoloration layer) is coated on high-quality base paper, a thermal discoloration layer film of the thermal paper is heated in a temperature range provided by a printing head of a thermal printer, the film melts, a color substance performs color reaction, and characters with different colors appear on colorless thermal paper; the thermal paper is used as a communication carrier of characters and graphics on the fax machine, namely as fax paper; the material can be used as recording material in medical and measuring systems, such as electrocardiogram paper, thermal instrument recording paper, etc.; printing paper applied to an internet terminal; in the commercial field, it is used to make trademarks, signatures (POS), etc.
According to the requirements of the national standard, the quantitative grammage of thermal paper is 50 g/m-200 g/m, the lowest grammage of thermal paper being restricted to 50 g/m. The requirement is mainly to meet some functional indexes, because the papermaking raw materials are better and better, the technology is higher and higher, the thickness of the thermal paper is lower than the national standard, the functional indexes can be completely met, and the increase of the printing area can reduce the unit price of the paper while the requirement of the printer is met. The thermal sensitive paper which is out of the national standard quantitative range can increase the use area, reduce the use amount of trees, reduce the production cost and relieve the environmental protection pressure. The strength and the thickness index are taken into consideration, and the printing requirement and the storability requirement are met. When the thermal paper ration was transferred down, corresponding adjustment was also made to thickness, under the prerequisite of guaranteeing the printing definition, reduced thickness can alleviate thermal printer's the printer head wearing and tearing of beating, the life that the extension beaten the printer head. With the development and vigorous implementation of national energy-saving and emission-reducing policies, the consumption of wood in unit area is reduced, and the trend of the development of paper-making enterprises is reached; the requirement of the market is met, and the development of low-quantitative thermal paper becomes the development trend of the thermal paper.
Disclosure of Invention
In order to solve the above problems, the utility model provides an ultralow quantitative thermal sensitive paper.
The purpose of the utility model is realized through following mode:
the utility model discloses an ultralow ration thermal sensitive paper, including paper base layer 1 and coating 2, paper base layer 1 surface scribble ultralow ration thermal sensitive coating 2.

Detailed Description
In order to make the objects, technical solutions and advantages of the present invention clearer, the drawings of the embodiments of the present invention are combined below to clearly and completely describe the technical solutions of the embodiments of the present invention, and obviously, the described embodiments are only a part of the embodiments of the present invention, not all embodiments. Based on the utility model discloses the embodiment of applying for, to the technical personnel of this field, a plurality of changes and improvements etc. that make, all other embodiments that obtain all belong to the scope of the utility model protection.
The utility model discloses an ultralow ration thermal sensitive paper as shown in figure 1, including paper substrate 1 and coating 2, paper substrate 1 surface scribble ultralow ration thermal sensitive coating 2.
The ultralow-weight thermosensitive coating 2 has the gram weight of 1 g/m-6 g/m.
The ultralow quantitative thermal coating 2 gram weight of 2 g/m, 4 g/m, 5g/m has been.
The paper base layer 1 gram weight of 25 g/m-40 g/m has been removed.
The ultralow-weight thermal paper gram weight of 30 g/m-45 g/m has been completed.
The utility model discloses the working process of the low wearing and tearing thermal sensitive paper of preparation as follows:
the utility model discloses the higher body paper of roughness is selected to the ultralow quantitative thermal paper of preparation, paper-based layer, and the ash content of body paper reduces, and the low tension resistance of ration is big, can guarantee that the thermal paper of preparation formation has great pulling force and cohesion, satisfies the will of national standardSolving; the coating amount is 7.5g/m of that of common thermal paper2The reduction is 1 to 5g/m2The coating amount is reduced, so that the thickness of the prepared thermal sensitive paper is reduced, and the prepared thermal sensitive paper can still meet the national standard; the utility model discloses the ultralow ration thermal sensitive paper of gram weight between 30 g/m ~45 g/m of preparing, through thermal printer or thermal fax machine in-process, because of its single-sided light five-line body paper that chooses for use that the ash content is low, quantitative resistance tension is big, guaranteed the functional requirement of paper, reduce the coating volume of scribbling simultaneously, the utility model discloses when the thermal printer for ultralow ration thermal sensitive paper prints, the distance of paper and printer head is more suitable, and the print writing is clear, reduces the degree of wear to the printer; the utility model discloses a low ration temperature sensing paper reduces the ligneous consumption of unit area, practices thrift national resources, makes partial contribution for the environmental protection simultaneously.
