रिकर्ड-रखने-वाला इसके अंग्रेजी अर्थ का उदाहरण

When a fluid coupling is used for braking it is also known as a retarder.

It is also used in lubricating oils, and as a solvent evaporation retarder in paint removers.

Technically, many of these materials are only vapor retarders as they have varying degrees of permeability.

American building codes have classified vapor retarders as having a water vapor permeance of 1 perm or less when tested in accordance with the ASTM E96 desiccant, or dry cup method.

Vapor diffusion retarders are normally available as coatings or membranes.

The membranes are technically flexible and thin materials, but sometime includes thicker sheet materials named as "structural" vapor diffusion retarders.

The vapor diffusion retarders varies from all kinds of materials and keep updating every day, some of them nowadays even combined the functions of other building materials.

Materials used as vapor retarders:.

Advanced Polyethylene vapor retarders that pass the ASTM E 1745 standard tests ≤0.

Vapor retarder paints (for the air-tight drywall system, for retrofits where finished walls and ceilings will not be replaced, or for dry basements: can break down over time due to being chemically based).

A vapor retarder and an air barrier serve to reduce this problem, but are not necessarily interchangeable.

Vapor retarders slow the rate of vapor diffusion into the thermal envelope of a structure.

How, where, and whether a vapor barrier (vapor diffusion retarder) should be used depends on the climate.
