Stitch màts for thermal isolation
Technical specifications ÒÓ Ó Â.2.7-21.356-99
Stitch màts are intended for thermal isolation of the equipment and pipelines, and also buildings in industrial, civil and housing construction. Limit of temperature of surfaces which are isolated:
- at use of mats of all marks in a facing from glass fabric, except for mark ÌÒÏÑ, - 723 K (+450 Ñ);
- at use of mats without a facing - 973 K (+700 Ñ) in case of application of cloths from superthin glass staple fibres for the building purposes and 1173 K (+900 Ñ) in case of application of cloths glassmicrocrystall staple;
- at use of mats of MTPS marks which are applied only in a facing from glass fabric, 453 K (+180 Ñ).
Technical specifications are suitable for the purposes of certification.
For facing and insertion of mats are applied such materials:
for facing
- fiber glass fabric of mark À 1x95 GOST 8481;
- fabric made from glass complex lisle thread GOST 19170;
- a fabric for electric isolation from glass lisle thread complex strings GOST 19907;
- fiber glass fabric marks ?-23 on THAT 6-11-231;
for insertion
- roving from glass lisle thread GOST 17139;
- glass lisle thread GOST 8325;
- siliceous lisle thread GOST 6-11-389.
For thermal isolation of pipelines is recommended to use a winding atop of mats by fibreglass ÐÑÒ-200Ë, impregnated with latex.
