Has the advantages that: the parchment paper prepared by the invention is prepared by pure handwork and is original ecology, one parchment paper is prepared from one parchment, has good fireproof performance, can be widely applied to the fields of spray painting photo albums, spray painting landscape paintings, spray painting antiques, spray painting calligraphy, spray painting family tree, spray painting books and the like, has wide application range, and can be stored for hundreds of years, so that the parchment paper has better use value.
Description
Technical Field
The invention relates to the field of parchment paper manufacturing, and relates to a raw parchment paper making method and application thereof.
Background
Parchment, also known as industrial parchment, is a translucent wrapping paper, which is a material for making books or providing writing. It is mainly used for packaging machine parts, instruments, chemical drugs and the like. The main raw materials for manufacturing the parchment paper are chemical wood pulp and rag pulp.
However, the existing parchment paper has the defects of small performance difference with the traditional parchment paper and poor fire resistance, is inconvenient to use in the inkjet industry, realizes long-term storage of the parchment paper, reduces the use value of the parchment paper, and is mainly manufactured in batches by adopting mechanical equipment in the production process, so that the production efficiency is good, but the parchment paper is not ecological enough, and the quality cannot be guaranteed.
Disclosure of Invention
The invention aims to solve the problems and provide a raw sheepskin papermaking method and application thereof.
The invention realizes the purpose through the following technical scheme:
a raw sheepskin papermaking process comprising the steps of:
step 1: soaking raw sheepskin in water for two days, changing water for three to four times a day, cleaning until the sheepskin is washed white, soaking the sheepskin to enable the subsequent treatment of the sheepskin to be more convenient and fast, thoroughly washing the sheepskin white, and ensuring the final quality of sheepskin paper;
step 2: fishing out the raw sheepskin processed in the step 1, airing water, airing the raw sheepskin, and facilitating the subsequent processing of the raw sheepskin;
and step 3: after putting into white ash bucket bubble a period of time in will be through step 2 raw sheepskin after handling, steep in white ash bucket, fish out and remove hair fleshing and handle, the lime can take place to react the release heat after meeting water, will give birth to the sheepskin and steep in white ash bucket, not only makes the bacterium on the raw sheepskin can be effectually killed, is convenient for go out the hair to the sheepskin and removes the meat processing moreover.
And 4, step 4: washing the raw sheepskin treated in the step 4 with saline back and forth for 1 hour and a half, and then soaking talcum powder with clear water for 8 hours, wherein the talcum powder has excellent physical and chemical characteristics of lubricity, viscosity resistance, flow aid, fire resistance, acid resistance, insulativity, high melting point, chemical inactivity, good covering power, softness, good luster, strong adsorption power and the like, so the raw sheepskin paper treated by the talcum powder has good fireproof performance;
and 5: and (4) the raw sheepskin treated in the step (4) is again washed with water and then put on a shelf and scraped by hands to prepare the sheep skin.
Furthermore, edible baking soda and edible salt are required to be added when water is changed for the last time in the step 1, the baking soda is easily decomposed by heating, and the reaction is started to generate CO at about 50 DEG C2All of which are changed into sodium carbonate at 100 ℃, and the parchment paper is treated by adding sodium bicarbonate to ensure the fireproof performance of the parchment paperIs further improved.
Further, the brewing time in the step 3 is 40 hours.
Furthermore, the parchment paper prepared by the steps can be widely applied to the fields of spray painting photo albums, spray painting landscape paintings, spray painting antiques, spray painting calligraphy, spray painting family tree, spray painting book books and the like.
The invention has the beneficial effects that:
the parchment paper prepared by the invention is prepared by pure handwork and is original ecology, one parchment paper is prepared from one parchment, has good fireproof performance, can be widely applied to the fields of spray painting photo albums, spray painting landscape paintings, spray painting antiques, spray painting calligraphy, spray painting family tree, spray painting books and the like, has wide application range, and can be stored for hundreds of years, so that the parchment paper has better use value.
Detailed Description
The invention is further illustrated by the following examples:
example 1
A raw sheepskin papermaking process comprising the steps of:
step 1: soaking raw sheepskin in water for two days, changing water for three to four times a day, cleaning until the sheepskin is washed white, soaking the sheepskin to enable the subsequent treatment of the sheepskin to be more convenient and fast, thoroughly washing the sheepskin white, and ensuring the final quality of sheepskin paper;
step 2: fishing out the raw sheepskin processed in the step 1, airing water, airing the raw sheepskin, and facilitating the subsequent processing of the raw sheepskin;
and step 3: placing the raw sheepskin treated in the step 2 into a lime bucket for soaking for a period of time, then soaking in the lime bucket, fishing out for unhairing and fleshing treatment, wherein the lime can react with water to release heat, and the raw sheepskin is soaked in the lime bucket, so that not only bacteria on the raw sheepskin can be effectively killed, but also the raw sheepskin can be conveniently unhaired and fleshed;
and 4, step 4: washing the raw sheepskin treated in the step 4 with saline back and forth for 1 hour and a half, and then soaking talcum powder with clear water for 8 hours, wherein the talcum powder has excellent physical and chemical characteristics of lubricity, viscosity resistance, flow aid, fire resistance, acid resistance, insulativity, high melting point, chemical inactivity, good covering power, softness, good luster, strong adsorption power and the like, so the raw sheepskin paper treated by the talcum powder has good fireproof performance;
and 5: and (4) the raw sheepskin treated in the step (4) is again washed with water and then put on a shelf and scraped by hands to prepare the sheep skin.
In this embodiment, in the step 1, edible baking soda and edible salt are added when water is changed for the last time, the baking soda is easily decomposed by heating, and the reaction starts to generate CO at about 50 ℃2The sodium carbonate is completely changed at 100 ℃, and the raw parchment paper is treated by adding sodium bicarbonate, so that the fireproof performance of the parchment paper is further improved.
In this embodiment, the brewing time in step 3 is 40 hours.
In the embodiment, the parchment paper prepared by the steps can be widely applied to the fields of spray painting photo albums, spray painting landscape paintings, spray painting antiques, spray painting calligraphy, spray painting family tree, spray painting book books and the like.
The above description is only for the purpose of illustrating the preferred embodiments of the present invention and is not to be construed as limiting the invention, and any modifications, equivalents, improvements and the like that fall within the spirit and principle of the present invention are intended to be included therein.
