SU97816A1 - The method of manufacture of mineral wool slate and other mineral wool products and solutions - Google Patents

Description

The subject of the invention is a method for the manufacture of slate and other products made of mineral wool and cement (cement, etc.) with the addition of asbestos or other L50 laminated materials.

A distinctive feature of the method is that, with the aim of ycTpaiieiiHH clumping, the 1st wool mineral when mixed with water or aqueous suspension into a binder, fused asbestos or other fibrous materials capable of creating durable suspensions and adsorption of mineral wool are introduced into the latter.

The main components of the raw materials are:

1) water or water suspension into the slurry;

2) fibrous material capable of creating for a period of mixed and /; resistant suspensions and adsorb mineral wool (asbestos, etc.):

3) mineral wool;

4) in the grub (tsement, etc.). Odpnm of application examples.

invention 1; is prepared above mineral slate. In this case, with. “Less asbestos consumption

the products have physical and mechanical properties equal to asbestos-cement. In mortars and concretes, cement consumption is reduced by no less than 209 °, without reducing their mechanical properties.

Asbestos slate and other mineral wool products can be manufactured in the following ways:

i) using a sheet forming machine (pappmashina)

I) using vacuum pressing.

By.:; In method 1; Production of products made from the following main operations:

a) cleaning. mineral wool, - in a special aniarate;

b) preparation of fiber material capable of creating durable suspensions and adsorb mineral wool (further on jiMe and fiber “a):

c) a mixture of fibrous material capable of creating persistent suspensions with the mineral GAT ;.

Mixing is done in the same glender. in which the fiber of the clear substance was fluffed up (by clause b): Filling procedure: the glender consists in first creating a uniform BSiit Cb in fiber water and then introducing mineral wool into the slurry. In this case, naked about 5-10 minutes of gollender's work, a uniform suspension is obtained in the water of the fiber a; | Ineral wool PCh.pm§1 is unified “and Kt is a hollender of the mnn schalrypata aneer fiber” and njOiiHOfl uniformity is sufficient |: a: n | p «1, and not; cement; n1 cement is reached. t) c. suspended in water microlitel wool and fiber “a with cement. In the resulting, as indicated in Mon. “B” and “in operations, a uniform suspension of mineral matter and fiber” and cement is added, after which all loaded glender components are mixed for 7 minutes. e). in the gallery, the mass is poured into the net and from there it enters the bath of the net jiH.iHiiApa listophorl machine. Further operations are similar to those for PRS) ;; svstvt1; e asbestos products; ;. According to the second method. The manufacture of the raw mass is composed of the same operations, followed by: a) pouring the finished mass into a spare tank equipped with a stirrer and storing it in it; b) mass dosing per unit of product. To this end, the mass is not transferred to the dosing tank, also equipped with a stirrer; c) the filling of form. vacuum-press with mass. In order to ensure uniform distribution of the mass in the form, the filling of the latter is made from several dispensers, each with dispensers from each of the dispensers should be located no more than 30-40 cm from the next g) zakumutosos moisture from the mass with simultaneous pressing under pressure 50-100 kg1cm. The pressing of finished raw sheets can be carried out in presses or by rolling iodine with a heavy (gauch) shaft. This process takes place under conditions that are different from those previously known, namely, the nervous system. to be such that ;; and the delamination of the natives of the cement and the fiber are occurring; fiber; x aggregates.
