Embodiment 1
[0029] A method for making rice paper, comprising the following steps:
[0030] S1 Green sandalwood peeling: Soak green sandalwood in cold water at 0-1°C for one day and one night, then soak in hot water at 90-100°C for one day, then peel the green sandalwood to obtain green sandalwood bark, and dry;
[0031] S2 Bleaching of green sandalwood bark: Soak the dry green sandalwood bark in warm water for 4-8 days, add pectinase to the water, cook in water for more than 16 hours, add plant ash and lime to the water, then cool the water to room temperature and simmer for 12 hours Remove and drain above, put into bleaching agent to bleach until the green sandalwood bark turns white, then rinse repeatedly with clear water to rinse away the bleaching agent remaining on the green sandalwood bark;
[0032] S3 green sandalwood bark pulping: smash green sandalwood bark, use molecular sieve to sieve all the green sandalwood bark fibers above 5mm, then add water, stir and mix the green sandal...
Embodiment 2
[0046] Steps S1-S6 are the same as in Embodiment 1, except that:
[0047] S7 pulping: mix the green sandalwood pulp and straw pulp together for pulping, and add epoxy resin during the pulping process, and then filter the water to make the moisture content in the mixed pulp be 50-60%;
[0048] S8 papermaking: add vegetable gum dispersant to the mixed pulp, and then use bamboo screen to make paper to form paper paste;
[0049] S9 Baking: put the paper paste that has not been drained into a baking device to dry;
[0050] S10 Inspection, cutting and packaging: peel off the dried paper and stack it neatly, then send it for inspection, cut and pack the paper.
[0051] The rice paper made by using the invention has good uniformity, pure white and dense texture, clear texture, good ink moistening, can effectively retain pen and ink, ink spreads evenly, and does not appear jagged. In addition, the made rice paper is not easily deformed and stable. Well, it can be stored for a long ti...

Abstract
The invention discloses a Xuan paper manufacturing method, which comprises the steps of pteroceltis tatarinowii peeling, pteroceltis tatarinowii bark bleaching, pteroceltis tatarinowii bark pulping, straw pretreatment, straw bleaching, straw pulping, pulp mixing, papermaking, draining, baking and inspection, cutting, and packaging, wherein pectinase is added in the pteroceltis tatarinowii bark bleaching process, and a layer of epoxy resin is brushed in the baking process. According to the method, the manufacturing period of Xuan paper can be greatly shortened; the epoxy resin is immersed into the Xuan paper in the baking process, so that the connection strength between fibers is enhanced, the internal gap distance of the Xuan paper is reduced, and the air permeability is good; pectinase is added in the pteroceltis tatarinowii bark soaking process, so that complete pteroceltis tatarinowii bark fibers can be extracted, and the alkali consumption is reduced; the Xuan paper manufactured by the method is pure white and fine in texture, clear in texture, good in ink wetting property, capable of effectively retaining pen ink, uniform in ink diffusion and free of sawtooth; and the manufactured Xuan paper is not easy to deform, good in stability and capable of being stored for a long time.
Description
technical field [0001] The invention relates to the technical field of papermaking, in particular to a method for making rice paper. Background technique [0002] Xuan paper has a long history of production and is a typical representative of traditional handmade paper. The selection of materials for Xuan paper is closely related to the geography of Jing County, the place of origin. Green sandalwood bark is one of the main local tree species, so green sandalwood bark has become the main raw material of rice paper. And because rice is grown locally, its rice has also become one of the raw materials. [0003] The production of rice paper can be roughly divided into 18 processes, and if subdivided, it can exceed Shangbaidao. The traditional method of cutting rice paper is to steam the branches of Qingtan tree first, then soak them, then peel them off, dry them in the sun, add lime and soda ash, and steam them again to remove impurities. After washing, tear them into thin stri...
