Is there mercury in the refill, and what is the use of the mercury pen

The chemical composition of ballpoint pen oil is mainly some colored substances (dyes, pigments, etc.) and some oily substances (hydrocarbons, greases, etc.), as well as some solvent substances for adhesion (such as glycerin, alcohol, etc.), and some pen oils are also mixed with some flavors and other pigments.

Ink is the correction of writing instruments, such as the use of fountain pens, and can be divided into blue-black ink and color ink from the chemical properties of its raw materials.

1) Blue-black ink, also known as iron tannins ink, is composed of blackening and long-lasting ingredients, pigments, stabilizers, resists, wetting agents and preservatives.

Blackening and long-lasting ingredients: mainly tannic acid (C4H10O9), gallic acid (C7H6O5?).H2O) and ferrous sulfate (FeSO4) and other components are combined with each other to form ferrous tannin and ferrous gallate, which become insoluble ** iron after oxidation, that is, iron tannin and ferric gallate, the former enhances water resistance, and the latter enhances blackening, so that the ink is water-resistant, black, and the color is long-lasting.

Pigment composition: At present, the commonly used are acid ink blue and direct lake blue dye, black water blue is the main color of ink, the aqueous solution does not deteriorate when it encounters acid, but it becomes brown when it encounters alkali. Direct lake blue plays a color-aiding role in ink, because it contains more impurities, it should not be used more, and it is easy to grow mildew in a humid environment.

Stabilizer: The purpose of adding stabilizer to ink is mainly to eliminate the precipitation of ink, so as to avoid water interruption when writing. Commonly used stabilizers are sulfuric acid (HSO4), oxalic acid (COOH)2, and formaldehyde (HCO) solutions.

These stabilizers are all acidic, which has buried potential hazards for paper acidification, and should not be used more.

Resist: Because the stabilizer added to the ink has strong acidity, in order to prevent corrosion, a resist is often added to make it form a thin film with iron to reduce the corrosive effect of sulfuric acid 90. The iron content in the ink does not increase due to corrosion of the nib, thus increasing the stability of the ink.

Wetting agent: In order to prevent the evaporation of water in the ink and cause inconvenience in writing, glycerol C3H5(OH)3, which is not volatile and absorbent, is added to the ink to keep the nib moist and facilitate writing.

Preservatives: Organic substances and other substances contained in ink raw materials are easy to rot and mildew in a humid environment, so in order to prevent decay, phenol or sodium pentachlorophenol and other agents are often added as preservatives.

2) Pure blue ink and red ink Pure blue ink and red ink are organic dye inks, although the color is bright, but the firmness of the handwriting is not as good as the blue and black ink, and its handwriting is easy to fade. The red ink fades and seeps quickly when exposed to water, so special attention should be paid to it.

Summary. Hello, the mercury pen is mainly used to make marks, the designed model is drawn on the leather surface with a pen, and you can cut it according to the drawn line. It is recommended to purchase a matching leather silver pen cleaning pen, and the line drawn by the silver pen can be wiped off with a cleaning pen.

It is recommended to use a tracing pen for vegetable tanned leather, and it is not recommended to use a silver pen and hydrolysis pen.

Is the mercury pen poisonous.

Mercury pens are non-toxic and have undergone special treatment.

If it's poisonous, it's not allowed to be produced.

Is there mercury in a mercury pen.

There is mercury. However, the amount of mercury contained is very small. It will not cause harm to the human body.

It is very seriously treated.

This is reassuring.

There is no mercury in the refill.

Neutral refills, ballpoint refills, pencil refills, water-based refills and other refills generally do not put mercury. After all, mercury is a poisonous, chemically stable, insoluble hail in acid or alkali, and is chronically highly toxic, which is not good for the human body. Therefore, there will be no mercury in the refill, the bottom of the general refill pants is to place a small iron ball, through the activity of the iron ball, the liquid in the refill comes out, and the top of the neutral refill is blocked by a layer of wax oil, to avoid the liquid leakage in the refill, only the iron ball activity, the liquid will come out, the full name is based on this principle to operate.

So, there is no mercury in the refill.

You can take out the refill and shake it a few times.

There are also several ways to deal with it:

1. The method is very simple, and 100% easy to use, after taking out the refill, use the game lighter to bake the metal nib for two seconds, and then grab the tail of the ballpoint refill, and throw it two or three times in the direction of the nib.

2. Soak the tip of the pen in hot water for about 10 minutes, preferably two-thirds of the refill in the hot water, and then repeatedly circle a piece of paper until you can write it.

3. See if the beads are broken, if so, the pen can be scrapped.

Ink characteristics. Ballpoint pen ink is usually a paste containing about 25 to 40 dyes. The dye is suspended in a mixture of solvents and fatty acids.

The most common solvents are benzyl alcohol or phenoxyethanol, which mix with dyes and oils to form a smooth paste that dries quickly.

When writing, fatty acids help lubricate the nib. Hybrid ink also contains added lubricant in the ink to provide a smoother writing experience. The drying time of the ink depends on the viscosity of the ink and the diameter of the ball.

In general, the higher the viscosity of the ink, the faster it dries, but dispensing the ink requires the application of more writing pressure. However, despite their less viscous, hybrid inks have a faster drying time compared to regular ballpoint pen inks. Similarly, larger balls will distribute more ink and therefore increase the drying time.

The dyes used in the blue and black ballpoint pens are basal dyes based on triarylmethane and diazo compounds or phthalocyanine-derived acid sockish dyes. Common dyes in blue (and black) inks are Prussian blue, Victorian blue, methyl violet, crystal violet, and phthalocyanine blue. The dye eosin is commonly used in red inks.

Inks are water-repellent after drying, but can be smeared with certain solvents, including acetone and various alcohols.

The clear liquid behind the refill is a special sealant "lithium ester".

This sealant is well suited as a tail plug for gel pen refills because it seals the ink in the barrel to prevent evaporation or backflow, and follows the seal as the ink decreases during the writing process. The "lithium ester Huiyan" used in pen making is required to be incompatible with neutral ink pre-silver water, and the interface is clear; No bubbles, anti-evaporation; It has good stability at high and low temperatures, and has good fluidity with thixotropy.

Refills that run out of water can be used to make crafts.

First, the following is an introduction to the production of a handicraft:

2.Unplug or cut off the front part of the used water refill:

4.Wash off any ink residue on the inner wall of the refill with water.

5.Wash and dry the segments, making a small cut in each segment.

Don't throw away the used refills, they are especially "valuable" when they are placed in the trash, and the neighbors follow suit.

<> is a kind of grease, non-toxic but inedible, the role is to prevent the ink leakage in the refill, a compound ester containing polysilicone, a special sealant, commonly known as "lithium ester". It is suitable for the tail plug of the gel pen refill, that is, it seals the ink in the pen barrel to prevent evaporation or backflow, and follows the seal as the ink decreases during the writing process. Therefore, this product can be regarded as a "liquid piston".

The "lithium ester" used in pen making is required to be incompatible with neutral ink and have a clear interface; No bubbles, anti-evaporation; It has good stability at high and low temperatures, and has good fluidity with thixotropy. Keep a good moisturizing seal in the case of large temperature changes to prevent ink evaporation or backflow overflow. It is also required that the sealant can be followed up at any time when writing quickly, and less touch the wall of the tube, so as to ensure that it can be followed up until the ink is finished.

Now there are three kinds of pens, one. Fountain pen II. Water-based pen III. Ballpoint pen.

There are three types of refills for water-based pens: one. Half Needle Tube II. Full needle tube III. Bullets.

A fountain pen is a pen that punches ink, a ballpoint pen is a pen with a spring, and a water-based pen is in the middle of them.

Distinguish from oily characters that are easy to imprint.

Write a refill of water, no matter what it is.

It's a gel refill, isn't it?
