Embodiment 1

[0030] A pipe moistening agent applied to concrete pipeline transportation, the active ingredient of which is made of the following raw materials according to the weight ratio: polyacrylamide: 40 parts; hydroxyethyl cellulose: 55 parts; pull-off powder: 3 parts parts; retarder: 6 parts.

[0031] The way to use the moisturizer is:

[0032] 1. Inspection before pumping: Check whether the hopper of the concrete conveying equipment (pump truck, tow pump, vehicle-mounted concrete conveying pump) and the conveying pump pipe are leaking; the hose at the front end of the pump pipe should droop naturally; there should be no residue in the pump pipe When pumping, the hose at the front end of the pump tube must be in a natural drooping state. After opening, the hose can move laterally.

[0033] 2. Dosage: Use 250g for the pump tube length within 100m, add 40-50kg of water; use 500g for the pump tube length of 101-200m, add 80-100kg of water; and so on.

[0034] 3. Before use, slowly po...

Embodiment 2

[0037] A pipe moistening agent applied to concrete pipeline transportation, the active ingredient of which is made of the following raw materials according to the weight ratio: polyacrylamide: 60 parts; hydroxyethyl cellulose: 35 parts; pull-off powder: 7 parts parts; retarder: 2 parts.

[0038] When in use, use 250g of pump tube length within 100m, and add 40-50kg of water.

Embodiment 3

[0040] A pipe moistening agent for concrete pipeline transportation, the active ingredient of which is made of the following raw materials according to the weight ratio: polyacrylamide: 50 parts; hydroxyethyl cellulose: 40 parts; pull-off powder: 6 parts parts; retarder: 3 parts.

[0041] When in use, use 350g of pump tube length within 100m, and add 40-50kg of water.

Abstract

The invention relates to a pipe lubricant used for pipeline transportation of concrete and a using method thereof. The effective constituents of the pipe lubricant include, by weight, 40-60 parts of polyacrylamide, 35-55 parts of hydroxyethyl cellulose, 3-7 parts of nekal BX and 2-6 parts of retarder. The pipe lubricant can be dissolved in water easily and quickly within 3-5 min through proper stirring, so that thick liquid is formed. The product is convenient to use, and inconvenience caused by on-site blending of multiple components is avoided. Harm to concrete quality, corrosion to rebars and conveying equipment and harm to human health and the environment are all avoided.

Description

technical field [0001] The invention belongs to the technical field of building materials, and in particular relates to a pipe moistening agent applied to concrete pipeline transportation and a using method thereof. Background technique [0002] Concrete is a commonly used building material, and concrete is mainly poured by pumping at the construction site. Before the concrete is pumped, the delivery pipeline must be wetted and lubricated with cement mortar to ensure the smooth flow of the delivery pipeline. However, the main components of cement mortar are cement and sand. Using cement mortar to moisten pipes, on the one hand, causes waste of resources and increases construction costs. There are hidden dangers in building quality in this way of moistening pipes. [0003] CN 102719307 B discloses a pipeline lubricant for pumping concrete viscous and a preparation method thereof, comprising the following components in parts by weight: 0.05-1.2 parts by weight of water-solub...
