When using the QCJ paint film impactor experiment, the layout should be reasonable, neatly arranged, and easy to operate. The personnel who use the paint film impactor for the first time must operate it under the guidance of skilled personnel and master it proficiently before performing independent operations. Our company's service: The logistics department arranges shipments in a timely manner, ensuring timely and safe delivery of goods. Our company sells mud density meters, mud viscosity meters, mud three piece sets, electric demoulders, lightweight penetration testers, soil penetration resistance meters, mud static shear force meters, soil free expansion rates, rock free expansion rates, soil permeameters, stainless steel ring cutters, etc.

Working principle of QCJ paint film impactor structure:

1. Structure (see Figure 1)

The instrument consists of (1) base, (2) tube seat, (3) pillow block, (4) punch rod, (5) locking screw, (6) positioning mark, (7) hook, (8) tube cover, (9) controller group, (10) heavy hammer, (11) graduated tube body, (12) impact pad, (13) screw, (14) impact block tightening nut, (15) pillar

Controller group (see Figure 2)

(1) Controller bottom (2) Controller screw (3) Controller spring (4) Controller cover (5) Controller slider (6) Control screw

2. Working principle:

The heavy hammer is fixed at the required height by the controller screw, and its height can be read from the positioning mark. Pressing the controller screw compresses the controller spring. At this time, the circular hole of the controller slider is aligned with the circular holes of the controller cover and the controller bottom, and the connected heavy hammer falls and hits the punch rod. The punch rod acts downward on the template that was previously placed on the cushion block. Then, the heavy hammer body is lifted and the tested template is taken out to observe the paint film test situation on the template.

parameter

(1) The length of the instrument scale is 0-50 centimeters, 0-100 centimeters, and the division is 1 centimeter. (Also available for sale are 120cm impactors)

(2) The heavy hammer weighs 1000 grams and is equipped with a detachable hook. The weight of the heavy hammer can be adjusted by adding or removing lead particles inside the body.

(3) The steel ball at the end of the impact rod is 8mm.

(4) The depth of inserting the impact rod into the concave hole of the pillow block is 2 millimeters.

(5) The curvature radius of the edge of the pillow block is 2.5-3.0 millimeters, and the diameter of the concave hole is 15 millimeters.

(6) The net weight of the instrument is 11 kilograms (0-50); 14 kilograms (0-100).

(7) The total weight after packing is 20 kilograms (0-50); 23 kilograms (0-100).

(8) The external dimensions of the instrument are 250 × 140 × 830mm (0-50); 250×140×1330mm（0-100）

Purpose:

This instrument is designed according to the GB1732-79 standard and uses heavy objects falling from a height to impact the paint film, in order to measure the impact strength of the paint film.
