Essential for sealing performance! Different Materials and Characteristics of Rubber Gaskets

Posted on August 11, 2020 by monovate

Gaskets are widely used to seal the stainless steel container. To use the container safely and correctly, compatibility with the gasket is very important, too.

In this article, we will introduce the materials used in the gaskets of stainless steel container.

For those who want to know the chemical compatibility of different gaskets This article illustrated the compatibility of chemicals and characteristics of each gasket material. If you want to learn more about what kind of gasket you should use, please read this article.

Main materials of gasket

Silicone rubber (Q)

Silicon rubber gasket has characteristics such as weather resistance, chemical resistance, non-adhesiveness, and ozone resistance. Also, it has excellent flame resistance, water repellency, electrical insulation, etc.

Not only for industrial purposes, the silicon rubber is also used for household products.

This is a standard gasket material for Nitto Kinzoku’s stainless steel sealed container.

Operating temperature range: -70 ° C to + 200 ° C

“Slant-Bottom Container”: An Advanced Type of Stainless-Steel Container

Posted on September 21, 2019 by monovate

Stainless-steel containers are often used at work, in factories, at home, as containers for storing raw materials, and as cooking utensils. Among those stainless-steel containers, there may not be too many people know “slant-bottom container” yet.

This time, we will introduce “slant-bottom container” which is a little different from ordinary containers.

What is a "Slant-Bottom" Container"?

A slant-bottom container has a bottom sloping toward the outlet. So, even if the container is not tilted, the liquid will naturally collected at the outlet. This mechanism is excellent in liquid discharging performance.

Normal Flat-Bottom Containers: Waste of liquid

Because there is a certain distance between the outlet and the bottom of the container, where liquid remains. And the liquid waste happens due to the difficulty of discharging the entire amount of liquid.

What is “Buff Polishing”?

Posted on September 17, 2019 by monovate

A beautiful stainless-steel surface shall reflects like a mirror.

Do you know that this beauty was created artificially, not by the nature of the material?

In general, the surface of the stainless-steel container is polished by hand in a finishing method called “buff polishing”(or “buff finishing”).

What you'll know from this article:

1. What are the methods and effects of buff polishing?
2. What are the disadvantages of buff polishing?
3. What does "Electrolytic polishing" mean? Why shall it be recommended to those people who think "a little bit of contamination is horrible"?

Why Stainless-Steel Containers getting rusted? How to avoid it?-Part2

Posted on August 29, 2019 by monovate

Measures to prevent rusting of stainless-steel containers

Make sure that no dirt, salt or moisture remains

Please wash the container to remove dirt and salt. After washing, never leave it in the wet place. Wipe it with a dry cloth and dry it well.

Be careful of scratches and "contagious rust"

We recommend you to handle the containers carefully in order not to make deep scratches where dirt and water could be accumulated. Please use soft sponge or waste cloth instead of metal or hard scrubbing brush when cleaning.
In addition, avoid contacting with other metals that are easy to rust for a long time could prevent the “contagious rust”.

Why Stainless-Steel Containers getting rusted? How to avoid it?-Part 1

Posted on August 17, 2019 by monovate

Recently we received some inquiries like “Even though it was made of stainless steel, it soon got rusted” from our customers.

Stainless steel is a very rust-resistant alloy of iron.

Indeed, compared to iron, it is quite hard to rust, but it doesn’t mean it doesn’t rust at all.

Why is stainless steel so resistant to rust?

When exposed to air, it will form a self-healing barrier!

When exposed to air, it will form a self-healing barrier!In stainless steel, chromium bonds with oxygen in the air (=oxidation) before iron, which causes rust, and forms a very thin passive film (protective coating) of a few nanometers.

The passive film is resistant to chemical change and it is so strong that can prevent iron from oxidation(=rust).

Passive coating can be damaged and torn, but it can self-heal in a moment, so it does not leave room for iron to rust.

When shall it be replaced? Replacement Guidelines for Packing/Gasket for Stainless- steel Containers – Part2

Posted on August 1, 2019 by monovate

You even can just buy one packing and one part

Consumables such as packing, lid, and lever band that come with your container can be purchased separately.
You can quote the price to the supplier or contact us via the inquiry form.
If you do not know the type of container or packing, please contact us with the following information.

Clip type sealed container (Example: CTH -18 to 47 H/CTB) Standard attached packing.
*There is an option of different materials.
*Its color is black.

*CR (chloroprene rubber) model: [PCA]

When shall it be replaced? Replacement Guidelines for Packing/Gasket for Stainless- steel Containers – Part1

Posted on July 11, 2019 by monovate

“Packing” and “gasket” are commonly used for sealed stainless steel containers and for connections to piping and peripheral components.

Because they are consumables, it is necessary to change them at the appropriate time. How often do you change the container?

The actual replacement time varies by the frequency of use and the contents, so this time we have summarized the general replacement guidelines for the silicone rubber seals [PQA] [PQB] [PQL] that come with standard airtight containers of our company.

Replacement guidelines for packing and gasket

When degraded

Is the packing worn out, broken or chipped?

If the packing is damaged, it may cause foreign matter to get mixed in, so please replace it with a new one immediately.

In addition to the cause of foreign matter, it can also cause leakage of contents or loss of sealing.
