In the laboratory laboratory, several methods are used: a1ctermetology CMia4H, a1NI 1Codes € 1H1C; IrO1B) A1H1 fluids.

The 1M1 method of a “lying drop” is known for determining the contact angle of the Sigmauvan mine. According to this method, one of the phases under study forms a horizontal horizontal surface, which is a Nan Nanewits IB liquid, in the form of a small Yuaply 1. Omchiaiai xapiaiKTerIt is determined by the boundary angle 8, which is formed between the surface and the solar cell at the junction point. Typex. The greater the angle in, the better the liquid wets the T1 solid surface. The contact angle is measured either by optical means or by means of an increase in the size of the droplet.

For the study, see, for example, porous bodies 1 and 1M1 powder | In a vertavalka version, a 1C tube with solid material is placed helically, |:; the machine xapiaK is measured by the speed of the transfer fluid and the fluid dummy in the tube at a pressure of excess pressure generated by idle air.

The most flattering technology; 1m solution: to the invention I | Vl, a device for determining the wetting ability of non-mixing fluids and solid bodies with liquids, made of horizontal glass: H1H1Noy tube and measuring tubes 2. The excess pressure creates a liquid column, which is in the vertical part of the tube. The speed of the movement is measured by the displacement of the front of the fluid IB M atheri, ale. The harp actor is a peculiarity of the pipe method; ok is that the liquid and powder are in the same T ' s, therefore, the smearing of the tube is superimposed on the wetting of the powder.

Accounting for VL1IYaNII overpressure, and CKOpOiCTb c & 4iv, powder powder, and contact angle determination, especially on a heterogeneous surface, ovlz-any with great experts (mp and 1) and research problems. -index damage at the same time is impossible.

A contact is made (rubbing with the surface to be examined. As a result, the liquid flows out of the siphon.

With the help of seconds, the seeding of the outflows of the determined liquid levels on the scale 2 is seeded. By knowing the internal diameter of the tube, the wetting rate is recalculated to the volume and expressed in the time coordinate - volume.
