Problems solved by technology

The disadvantage of the above method is that the external sterilization smell is relatively large, and it can only kill the existing bacteria, and has no effect on the bacteria attached thereafter; adding bactericides to the pulp and white water can only kill the bacteria in the pulp and white water. For some bacteria, the fungicide loss is large during molding, and the distribution is uneven
Due to the large amount of fungicides, bacteria are prone to drug resistance, and the pulp still contains a small amount of bacteria, and it cannot prevent bacteria from reattaching

Embodiment Construction

[0017] The present invention will be described in more detail through specific embodiments below, and the content of specific embodiments does not limit the protection scope of the present invention in any way.

[0018] The papermaking process shown in Figure 1 includes beating, batching, flow delivery, online forming, drying, in-machine coating and re-drying. In the process of batching, flow delivery, and online forming, the ratio of 40 to 120ppm / ton Add fungicides (for absolute dry pulp), take 30-50 days as a cycle, adjust the type and proportion of fungicides once per cycle, add fungicides to white water under the net during online molding; add auxiliary fungicides to the headbox Retention agent.

[0019] The basic components of the above fungicide are isothiazolinone, octylisothiazolinone, non-oxidizing organic bromine, and DMDM ​​caprolactone.

[0020] When coating inside the machine, zinc oxide whisker antibacterial materials are added, based on the effective addition a...

Abstract

A paper able to kill and suppress bacteria features that it contains the crystal whickser of zinc oxide as the bacteria killing and suppressing material. Its preparing process and its application in culture, medicine, cigarette, food, etc. and also disclosed.

Description

technical field [0001] The present invention relates to a papermaking process, and more specifically, to a sterilizing and antibacterial paper, its manufacturing method and application. Background technique [0002] Existing methods for sterilizing paper mainly use sterilizing treatment on bacteria-carrying paper, such as radioactive or high-temperature disinfection, and some use infiltration sterilization to reduce or remove bacteria on the paper, or add bactericides to the pulp , such as isothiazolinone, for antiseptic and sterilizing treatment of pulp and white water. The disadvantage of the above method is that the external sterilization smell is relatively large, and it can only kill the existing bacteria, and has no effect on the bacteria attached thereafter; adding bactericides to the pulp and white water can only kill the bacteria in the pulp and white water. For some bacteria, the fungicide loss is large during molding, and the distribution is uneven. Due to the l...
