Description
Technical Field
The invention belongs to the technical field of cleaning, and relates to a method for cleaning oil stains on the surface of a paper cultural relic.
Background
Due to the influence of the factors and the external storage environment, the paper is often stained with various stains, such as oil stains, tea stains, water stains, mildew stains and the like. For some existing long-standing paper cultural relics, stains not only greatly reduce the ornamental value, the information research value, the historical value, the artistic value and the like of the cultural relics, but also can cause the cellulose of the paper to be acidified and hydrolyzed, damage the structure of the paper and damage the structure of the paper.
The oil stain is a common stain in paper cultural relics, and methods for cleaning the oil stain of the paper cultural relics at home and abroad comprise dry cleaning, wet cleaning, original potential chemical cleaning and the like, and the wet cleaning is the most common method for cleaning the oil stain of the paper cultural relics at present.
The surfactant commonly used for wet cleaning of paper cultural relics is mainly an ionic surfactant, such as 1.2% of sodium dodecyl sulfate used by people of Chen, Xiao and the like to clean oil stains on simulated paper, and the result shows that the oil stains become obviously shallow and basically meet the cleaning requirement of the oil stains, but the tearability, folding resistance and tensile strength of the paper are reduced (the research of oil stains of the paper cultural relics of Chen Li, Zhang jin Nu, Rong Jiang, Sun Da. research [ J ]. Chinese paper making, 2015, 34(07): 29-32.); the results of the inventor show that the soapstock powder has good cleaning effect and less influence on the physical and chemical properties of rice paper, the influence on the color of the paper can be reduced by repeatedly rinsing, and the soapstock powder as a plant source surfactant has good application prospect in cleaning oil stains (screening and evaluation of oil stain cleaning materials of paper cultural relics of Lanceolata, Tachys Erythroseum and Zhouhua [ J ] Wenbao, 2021(03): 94-100.).
The common wet cleaning is to soak the paper in the prepared cleaning agent and naturally dry the paper after cleaning, but the method has more cleaning agents and longer soaking time, and the cleaning agent is difficult to permeate into the internal structure of the paper, so that the cleaning effect is difficult to achieve the ideal effect.
Compared with an anionic surfactant, the nonionic surfactant has higher hard water resistance, has lower toxicity compared with a cationic surfactant and has lower cost compared with a zwitterionic surfactant; in addition, the nonionic surfactant is an amphiphilic structure molecule taking hydroxyl or ether bond as a hydrophilic group, is not ionized in water, is not easily influenced by strong electrolyte inorganic salt, acid and alkali, has good stability, and has good hard water resistance and low air bubble property. Compared with ionic surfactants, nonionic surfactants have the characteristics of low toxicity, low irritation, good biodegradability and the like. The nonionic surfactant is not applied to the removal of paper oil stains at present.
In addition, there is a cleaning method combining ultrasonic cleaning and wet cleaning in the prior art, for example, patent 2016213974707 provides an ultrasonic cleaning machine for paper cultural relics, which can soak the paper cultural relics to be cleaned in the cleaning agent in the cleaning machine, and start the ultrasonic cleaning to achieve the purpose of cleaning stains. There is also patent 2018212470406, which provides an automatic lifting paper cultural relic cleaning device, and the device cleans the paper cultural relic by soaking the paper cultural relic in the cleaning agent, as in the above patent. The ultrasonic cleaning method has the advantages that the cleaning agent used by the ultrasonic cleaning method is large in dosage, the paper cultural relics are required to be completely soaked in the cleaning agent, the cleaning time is long, the cleaning effect is poor, and the local cleaning treatment on the paper cultural relics cannot be carried out.

Further, the water bath heating temperature is 25-45 ℃.
Compared with the prior art, the technical scheme of the invention has the following beneficial effects or advantages:
1. the method adopts the ultrasonic permeameter to clean the oil stains on the surface of the paper, the probe of the ultrasonic permeameter is a 1-4 cm round probe, and the local oil stains on the paper can be cleaned.

The cleaning agent and the cleaning method used in the present invention were compared with those of ordinary oxidation cleaning.
Example 1
The cleaning effect test was performed using the cleaning agent prepared by the above method.
Step one, preparing a simulation sample: cutting raw rice paper into 16cm × 16cm, transferring 50 μ L rapeseed oil onto the raw rice paper, waiting for oil stain to spread to a circle with diameter of about 4.5cm, aging in a constant temperature and humidity environment box with temperature of 50 deg.C and relative humidity of 80% for 2 days, and taking out to room temperature environment for balancing for at least one day.
And step two, starting a handheld ultrasonic permeameter (model: Taidong 628A ultrasonic beauty instrument), selecting a continuous waveform, wherein the power intensity is 9 levels, the diameter of the probe is 4cm, the ultrasonic frequency of the probe is 1.1MHz, and preheating is carried out for 2-8 min.
The waveform of the Taidong 628A ultrasonic beauty instrument used in the test can be selected from continuous, discontinuous and pulse. The power intensity can be adjusted by 1-9 levels. The probe had a diameter of 4cm and 1 cm.
Step three, cleaning a simulation sample: and (3) placing a piece of filter paper with the same size under the simulation sample, transferring 10mL of the cleaning agent prepared by the method to the simulation sample in two times, placing the probe of the ultrasonic permeameter on the simulation sample after the cleaning agent completely soaks the simulation sample, and slowly looping in a circular shape for 5 min.
Step four, cleaning the residual cleaning agent: the simulated sample after ultrasonic penetration is placed on a stainless steel arch plate, and 20mL of ultrapure water is removed and washed on the simulated sample for four times.
And fifthly, naturally airing the cleaned simulation sample.
Comparative experiment: 2 traditional oxidation decontamination methods are selected.
Comparative example 1, 3% volume fraction NaClO solution wash: and (3) soaking the simulated paper oil stain sample in 200mL of sodium hypochlorite solution for 10min, and then washing and drying with 500mL of ultrapure water.
Comparative example 2 KMnO with 1% mass fraction 4 -H 2 C 2 O 4 Solution cleaning: soaking a simulated paper oil stain sample for 5min in 100mL of potassium permanganate solution, then soaking the sample in 200mL of ultrapure water for 5min, taking out the sample, soaking the sample in 100mL of oxalic acid solution by mass fraction until brown manganese dioxide is reduced to be colorless, and then washing the sample with 500mL of ultrapure water for 3 times and drying the sample.
The test result is shown in figure 1, and the result shows that compared with the traditional oxidation decontamination method, the cleaning agent provided by the invention has better cleaning effect. And compared with other traditional oxidation decontamination methods, the cleaning effect of the detergent after the wet heat accelerated aging is also remarkable.
The simulated samples obtained in the above examples and comparative examples were examined.
