Abstract

The invention relates to a sealant of a dipping specimen, which is characterized by comprising the following raw material in parts by weight: 100 parts of paraffin and 5-10 parts of rosin. The sealing technology of the dipping specimen comprises the steps: dewaxing, filtering, sealing and cleaning. Compared with the prior art, the invention has the advantages of favorable tightness, lowered cost, long retention time and the like and is simple and practical.

Description

The sealing compound of dipping specimen and Technology thereof

Technical field:

The invention belongs to dipping specimen, especially a kind of sealing compound of dipping specimen and Technology thereof.

Background technology:

Dipping specimen does not allow sample rot, go bad if think prolonged preservation, after the making sample is finished, just must carry out encapsulation process to bottleneck, vapors away with major ingredient formaldehyde or sulfurous acid or the alcohol etc. that prevent to preserve in the liquid; At present, paraffin sealing commonly used will directly be applied to bottle cap and body intersection after the heating paraffin fusing exactly.Exist paraffin easily to solidify, stopping property is poor, and easily comes off, and preserves validity period 1-2, so, all be a difficult problem for a long time, it is perplexing the people that are engaged in the dipping specimen making and preserve always.

Summary of the invention:

The sealing compound of the dipping specimen of the object of the present invention is to provide a kind of simple, practicality, good airproof performance, reduce cost, growing the shelf time.

Technical solution of the present invention is such, the contriver be engaged in teaching sample making with preserve existing two more than ten years, repetition test through in a few years draw a kind of not only simply but also practical, and effective sealing compound, used the present invention from 1991, preservation period is the longest existing 20 years, and sample is still intact, reaches purpose of the present invention.

The parts by weight of raw materials proportioning of the sealing compound of dipping specimen of the present invention is: paraffin 100, rosin 5-10.

The present invention compared with prior art, advantages such as having simple, practicality, good airproof performance, reduce cost, the shelf time is grown.

Embodiment:

Technology step of the present invention: 1. dewaxing and filtration: by above-mentioned parts by weight of raw materials proportioning: paraffin 100, rosin 8 are put into resistant to elevated temperatures china bowl and is built in and is heated to abundant fusing on the spirit lamp, after stirring, leave standstill, filter, and is stand-by.

2. seal: sample is put into bottle inject preservation liquid (not filling with), clean out bottle cap edge and bottleneck impurity; Step stand-by heating paraffin is 1. melted again, take a morsel with the writing brush or the cotton swab libation at an ancient wedding ceremony, be applied to bottle cap and bottleneck intersection, with spirit lamp the heating paraffin on bottleneck outer wall and top thereof (is noted not resting on for a long time a certain position then, in order to avoid bottleneck glass explosion), when the paraffin refuse, when the temperature of bottleneck glass reach a certain height, paraffin will slowly permeate along the bottleneck inwall, slowly rotate specimen bottle this moment, guiding paraffin flows down incessantly along a direction, until all spaces of filling up bottle cap outer rim and bottleneck inwall junction.

3. clean: after sealing wax finishes, remove bottleneck with pocket knife or blade and reach the unnecessary paraffin in bottle cap top all around, labelled.

Know-why of the present invention: paraffin after the fusing is penetrated in the slit of inside of specimen bottle bottle cap and bottleneck intersection, but not the surface, thereby reach the paraffin difficult drop-off, good seal performance, the purpose of long preservative period.

Claims

1. the sealing compound of a dipping specimen is characterized in that, described parts by weight of raw materials proportioning is: paraffin 100, rosin 5-10.

2. the sealing compound of dipping specimen according to claim 1 is characterized in that, described parts by weight of raw materials proportioning is: paraffin 100, rosin 8.

3. the sealing process technology of dipping specimen of the present invention is characterized in that, described Technology step:

1. dewaxing and filtration: by above-mentioned parts by weight of raw materials proportioning: paraffin 100, rosin 8 are put into resistant to elevated temperatures china bowl and is built in and is heated to abundant fusing on the spirit lamp, after stirring, leave standstill, filter, and is stand-by.

2. seal: sample is put into bottle inject preservation liquid, clean out bottle cap edge and bottleneck impurity; Step stand-by heating paraffin is 1. melted again, take a morsel with the writing brush or the cotton swab libation at an ancient wedding ceremony, be applied to bottle cap and bottleneck intersection, then with the heating paraffin of spirit lamp, when the paraffin refuse, when the temperature of bottleneck glass reach a certain height to bottleneck outer wall and top thereof, paraffin will slowly permeate along the bottleneck inwall, slowly rotate specimen bottle this moment, guiding paraffin flows down incessantly along a direction, until all spaces of filling up bottle cap outer rim and bottleneck inwall junction.
