5.1 Cryogenic system design - USPAS

Perlite is a commercial powder of random size and shape (cheap) Hollow glass micro-spheres (3M) of 50 to 200 µm in diameter Vacuum requirements are less critical. Good performance at p ~ 0.1 Torr compared to 10-4 torr for MLI Perlite is mostly used for less stringent cryogenic vessels such as LNG containers or LN 2 and LO 2

SECTION 2: INSULATION MATERIALS AND PROPERTIES

perlite, cellulose, diatomaceous earth and expanded polystyrene. 2.2.2 FORMS Insulations are produced in a variety of forms suitable for specific functions and applications. The combined form and type of insulation determine its proper method of installation. The forms most widely used are: 1.

Aggregates for Concrete

perlite, vermiculite, and diatomite are used to produce insulating lightweight concretes ranging in density from about 250 to 1450 kg/m. 3 (15 to 90 lb/ft. 3). Heavyweight materials such as barite, limonite, magnetite, ilmenite, hematite, iron, and steel punchings or shot are used to produce heavyweight concrete and radiation-shielding

Vermiculite Concrete

perlite, to give differing physical properties. Normally the type of cement used in these mixes is Ordinary Portland Cement (O.P.C), although a higher initial strength may be obtained using Rapid Hardening Portland Cement (R.H.P.C). For high temperature refractory applications, high alumina (luminate in the USA) cements may be used with great
