Condoms are something you use in your life, but do you know how condoms are made?Condoms have a long history of use and are the oldest method of contraception in history.In the 1990s, new technology greatly improved condoms, making condom manufacturing more advanced.The latest technological development is an innovation brought about by durex, which replaces latex with a unique raw material, polyurethane, making condoms thinner, stronger and more sensitive than before.Some people think that using condoms can extend the make love time, and thus feel more pleasure.Of course, at the beginning of the make love, when it comes to condom use, there will always be a variety of excuses, and even a variety of stereotypes, some answers may come in handy.

There is also an amazing tester in production - every condom goes through this level.A conveyor belt of stationary machines filled with erectile penises on which the woman would deftly slip a safety harness.

The rods are then lowered into a small tank by a conveyor belt, and two underwater electrodes are energized. If the stainless steel inside the condom conducts electricity, the condom is too thin or has a hole.

The condoms, which were heavily tested, were rolled into familiar rolls, sprayed with lubricant, spermicide or benzocaine and wrapped in foil.

Quality inspectors took random samples from the production line and took them to a "wet lab," where a team of experts filled the condom samples with clear water and yanked the balls.Another group of experts inflated them like balloons for a party, then pinched and tore at them.

Quality testing is crucial. If more than two out of every 1,000 finished products fail, the whole batch of products will be destroyed as required.

Here's how a condom is made:

Dipped a clean mold into a liquid latex emulsion tank filled with 21 ℃, the latex looks a lot like what we skim milk, coffee and then under the high temperature of 116 ℃ baking, then soak, bake again.As a result, six machines were churning out condoms on glass molds, producing more than half a million a day.In the reporter's two-hour visit, they produced sets that could last a lifetime.

Quality testing is crucial. If more than two out of every 1,000 finished products fail, the whole batch of products will be destroyed as required.Quality inspectors took random samples from the production line and took them to a "wet lab," where a team of experts filled the condom samples with clear water and yanked the balls.Another group of experts inflated them like balloons for a party, then pinched and tore at them.

There is also an amazing tester in production - every condom goes through this level.As rest running machines, conveyor belt, with an erect penis shaped object, lady will move deftly put a condom on it, then, the conveyor belt to the "stick" in a small tank, two water electrodes began to electricity, if condoms in the stainless steel is conductive, shows it condoms is too thin or with a hole in it.

The condoms, which were heavily tested, were rolled into familiar rolls, sprayed with lubricant, spermicide or benzocaine and wrapped in foil.So, stacked high in the middle of the numerous boxes, the quality of the condoms sleep for a while inside - waiting to be shown in the warmth of the country.

Condoms are one of the oldest and longest used contraceptives.The oldest condoms in existence are made from fish bladders, animal intestines and other materials, and require overnight soaking in warm milk before use (tut-tut, luxury and hassle).Modern condoms are much more convenient to use.And, contemporary condom has contraceptive function besides, still have prevent certain venereal, increase the function that the ancient condom such as appeal does not have.However, these handy little guardians are not at all convenient to make.

Who is the bride of the condom?

The most commonly used condom ingredient is natural latex.Presumably many children's shoes in the media have seen southeast Asia or China's hainan and other places to cut the rubber scene, the kind of white liquid from the rubber tree like drops of milk is the natural latex!

But before it can be used, natural latex needs to be chemically reacted with some ingredients at constant temperature, a process some manufacturers call "prevulcanization."The goal is to improve the elasticity of the condom and prevent it from aging.After this step, the ingredients are ready!

How does the condom look like this?

For condoms to look the way we think they do, it takes a stylist -- a mold -- to do the job.Different molds are printed with different patterns, which creates a wide variety of condoms, from threaded to floating-point condoms.

The clean mold is slowly immersed in the latex liquid at a constant temperature, which is then slowly pulled up and slowly rotated in clean air so that the latex liquid covers the surface of the mold evenly.After drying, repeat the steps of immersion and rotary drying several times. This will fill in the "hole zone" where the latex did not cover after the previous drying, eliminating the holes in the condom.

The forming process is very important for the final quality of the sleeve, so there are strict requirements and controls on the cleanliness of the mold, the running speed of the mold and the temperature of the latex.The condom, like the fetus in the mother's womb, is at an important stage of development.

When the thickness of the rubber film on the mold reaches the required thickness, the rubber film on the top edge will be rolled up and the familiar small rubber circle will appear.

At this point, the condom is already in shape.But getting rid of them is no easy task.They first need to be soaked in swelling water, and after a period of time, the condom is flushed down with a high pressure stream against the rubber ring.

The condom also needs calcium.

The stripped sleeve is also cured.First, the condoms are dehydrated (remember the blisters before they were peeled off?).And then put it into a sulfur device and heat it up.The goal of the vulcanization treatment is to make the condoms "stronger bones," making them stronger and more elastic!After filling "calcium", condom needs to rest a day or two, after waiting for their property to stabilize, be about to undertake check-up!

Check up before going public

The examination of condom includes complete examination, sampling examination, destructive examination, blame destructive examination to wait.Why bother?Because once the quality of substandard, it is likely to make contraceptive "unsuccessful, into a person."Therefore, in order to withstand future intense use, it is necessary to test the condom in advance!

First, each (note, each) sleeve must be electrode tested.The sleeve is encased in a mold-shaped electrode and immersed in an electrolyte solution containing the opposite electrode.When both electrodes are energized at the same time, check for current generation.If not, all condoms tested are qualified.Otherwise, defective condoms will be sorted and even all condoms in this batch may be discarded.

Electrical inspection of qualified condoms also need to carry out sampling inspection.Generally speaking, two sampling tests are required for the sleeve, one is water leakage test and the other is air blasting test.If a condom filled with water does not leak within a minute, semen should not leak inside the condom.In addition, if the inflatable volume of the sleeve can reach 18 liters, then it meets the requirements of the international latex minimum standards, otherwise it is not qualified products.

When packaged, the condom is rolled into the familiar shape of a coin, and lubricants, scented substances and other materials are added.Finally, after several rounds of selection, the condom is packaged in a bag and sealed.

Condoms are convenient to use but not convenient to make.Before the condom is sealed, it has to go through the configuration of raw materials, molding, testing and other processes.After knowing the production process, you will know whether the condom is safe or not.
