The continuous process-made vulcanized fibre could then be sheeted or wound up into rolls. The density of the finished vulcanized fibre is 2 to 3 times greater than the paper from which it starts. The density increase is the result of 10% machine direction shrinkage, 20% cross machine direction shrinkage, and 30% shrinkage in thickness.
Sensors measuring the paper quality (online meters) are attached to a sensor platform that move across the web guided by the scanner beam. A typical crossing time for a sensor platform is 10–30 s (an 8 m web, 60 cm/s). The sensor platform scans across the paper web and continuously measures paper characteristics from edge to edge.
Samsung says the silver nano technology sterilizes over 650 types of bacteria and that "Samsung WM1245A Washing Machine releases over 400 billion silver ions which penetrate deeply into fabrics of any kind and create a coat of sterilizing protection for a maximum of 99.99% disinfection and an added antibacterial effect of up to 30 days after ...
Set-off is measured at two different time intervals, 0.35s and 3s. A freshly printed surface is pressed against a paper after 0.35s and after 3s. Then the set-off density is measured. The idea behind selecting these two timings is to know what will be the set-off when the materials are used in a high-speed press and a low-speed press.
The density can be calculated by dividing the grammage of paper (in grams per square metre or "gsm") by its caliper (usually in micrometres, occasionally in mils). [1] The "ISO 534:2011, Paper and board — Determination of thickness, density and specific volume" indicates that the paper density is expressed in grams per cubic centimeter (g/cm ...
This type of washer is especially effective as a lock washer when used with a soft substrate, such as aluminium or plastic, [8] and can resist rotation more than a plain washer on hard surfaces, as the tension between washer and the surface is applied over a much smaller area (the teeth). There are four types: internal, external, combination ...
In 2009, the Alliance Laundry Systems University (ALSU) was founded as a corporate university available online to authorized Alliance Laundry Systems distributors, route operators and customers. [18] In March 2014, the Alliance Laundry acquired Primus Laundry Equipment headquartered in Gullegem, Belgium for approx. $259.4 million. [3] [19] [20]
Grammage and basis weight, in the pulp and paper industry, are the area density of a paper product, that is, its mass per unit of area. Two ways of expressing the area density of a paper product are commonly used: Expressed in grams (g) per square metre (g/m 2), regardless of its thickness [1] (known as grammage). This is the measure used in ...
