Description
Technical field
The invention patent relates to sample technical field more particularly to a kind of preparation methods of plant specimen.
Background technique
Making plant specimen is one of the powerful measure for solving the problems, such as botany teaching aid.If classroom teaching has the work of plant
Body is more favorable for student and deepens understanding.Using plant specimen, can be avoided Activities of Some Plants has regional, seasonal limitation.
Plant specimen saves the shape and color of plant simultaneously, so as to observation again and research in the future.A small number of plant specimens also have
There is the value of collection.Common plant specimen is exsiccata and resin sample, and usually fresh vegetable material absorbs water
Bookbinding sample made of (this paper is known as platform paper) on white hard paper after letterweight system is allowed to dry.However due in wax page sample
Plant be directly exposed in external environment, influenced the problems such as being easy to appear mildew, moth by humidity and air oxidation.
Resin sample is packaged plant specimen using resin, can completely cut off the influence of air and humidity to plant specimen, however resin
Need to inject resin fluid in-mold molding in the manufacturing process of sample, plant specimen be easy to be fluid affected appearance fold or
The deformation such as bending, are unfavorable for showing；Furthermore also with plant specimen physical and chemical reaction, which can occur, for certain resin materials goes out plant specimen
Situations such as now decolourizing.
Summary of the invention
The invention patent aims to overcome that the deficiencies in the prior art, provides beautiful and generous can be reserved for of one kind and works well
Plant specimen manufacture craft.
In order to achieve the goal above, the technical scheme adopted by the invention is that:
A kind of preparation method of plant specimen, comprising the following steps:
S1. plant pretreatment fluid is first prepared, the pretreatment fluid has identical acid group by ferrous salt and with the ferrous salt
Acid is formulated；
S2. plant sample is immersed in plant pretreatment fluid and is heated reaction, until translucent appearance is presented in plant sample；
S3. drying and processing is carried out to plant sample；
S4. plant sample tiling is put into transparent polybag, then vacuumize to polybag makes plant sample and modeling
Material bag fitting；
S5. the plant sample of packaging plastic bags is put into mold and mold is vacuumized to eliminate after injecting resin into mold
Bubble, then demoulding obtains finished product after hardening of resin.
Further, the plant pretreatment fluid includes ferrous sulfate and dilute sulfuric acid mixed liquor or hydrochloric acid ferrous iron and dilute hydrochloric acid
Mixed liquor or ferrous nitrate and dust technology mixed liquor.
Further, the molar concentration rate of ferrous salt in the plant pretreatment fluid and acid is 1:1, and the two is rubbed
Your concentration is 1 ~ 3.5mol/L.
Further, in the step S2, heating temperature is 65 ~ 70 DEG C, and heating time is 2 ~ 3 hours.
Further, the material of the polybag is in polyethylene terephthalate, polyethylene, polyamide or polypropylene
It is one or more of.
Further, the resin includes the raw material of following parts by weight: 90 ~ 99 parts of polymethyl methacrylate, fourth cyanogen 1 ~ 2
Part.
Further, in the step S5, polymethyl methacrylate pours into mold after mixing with fourth cyanogen vacuumize after, it is right
Resin carries out heating water bath until hardening of resin, wherein bath temperature is 45 DEG C 80 DEG C.
The beneficial effects of the present invention are: plant specimen of the invention is before being made as artificial specimen first with polybag pair
Plant specimen carries out Vacuum Package to carry out being protected from the ambroids such as resin material and directly connects with plant specimen to plant specimen
Touching causes resin and plant to generate physical and chemical reaction, while can also be conducive to plant specimen and keep preferably showing that form prevents resin
The bending of fluid driven plant specimen or folded deformation when pouring into mold.
Detailed description of the invention
Fig. 1 is the side sectional view of plant specimen of the invention.
Wherein, 1- resin layer, 2- polybag, 3- plant specimen.
Specific embodiment
De-protected technical solution is wanted to be described in further detail the present invention now in conjunction with specific embodiment.
A kind of preparation method of plant specimen in the present embodiment, comprising the following steps:
S1. plant pretreatment fluid is first prepared, the plant pretreatment fluid has same acids by ferrous salt and with the ferrous salt
The acid of root is formulated, and specifically in the present embodiment, the plant pretreatment fluid includes that molar concentration is 1.5mol/L sulphur
Sour ferrous and molar concentration is 1mol/L dilute sulfuric acid mixed liquor, and plant pretreatment fluid can be sub- for hydrochloric acid in other embodiments
Iron and dilute hydrochloric acid mixed liquor or ferrous nitrate and dust technology mixed liquor.
S2. plant sample is immersed in plant pretreatment fluid and is heated reaction, until plant sample is presented outside translucent
It sees；In the present embodiment, heating temperature is 65 ~ 70 DEG C, and heating time is 2 ~ 3 hours.Due in chlorophyll in acid condition
Magnesium elements just gradually replaced hydrogen ion, make the de-magnesium pheophytin of brown, therefore dilute sulphur can be used in the present embodiment
Acid replaces the magnesium in chlorophyll, then reacts the hydrogen for replacing its ferrous ion in chlorophyll with chlorophyll by ferrous sulfate
The metastable metal of chemical property is obtained for chlorophyll, so that plant specimen be made to keep green, there is sample good outer
It sees.
S3. drying and processing is carried out to plant sample, drying temperature is 60 ~ 80 DEG C, drying time about 2 ~ 3 hours, passes through drop
The rate and mildew of low inside plants hydrolysis.
S4. plant sample tiling is put into transparent polybag, then polybag vacuumize making plant sample
It is bonded with polybag；In the present embodiment, the material of polybag is polyethylene terephthalate, is gathered in other embodiments
One or more of ethylene, polyamide or polypropylene.Plant specimen after drying is put into polybag and is vacuumized
Sealing makes plant specimen and air exclusion that plant specimen be prevented to be mixed into oxygen during subsequent technique to cause to aoxidize, furthermore
Since the compactness of polyethylene terephthalate polybag is good, chemical stability height can by polybag to plant specimen into
Row protection, prevents resin and the direct haptoreaction of sample, while being easier in next work using the plant sample of packaging plastic bags
Sequence resin keeps original posture when pouring into, prevent plant sample from being deformed by resin fluid Foldable.
S5. the plant sample of packaging plastic bags is put into mold and injected into mold after resin to mold vacuumize with
