Summer coating, how to avoid the impact of sweat

Summer hot, hand sweat secretion more, hand direct contact with furniture board, hand sweat in the grease and water will cause a variety of coating problems. Therefore, the author found the relevant construction precautions for you to share.
summer coating construction precautions:
1, viscosity: compared to winter, spring and autumn viscosity appropriately lower 1 to 2s;
2, paint film thickness
: appropriate thin spray, especially deep conduit substrate, the first time can be opened thin under the guidance of professionals, increase the proportion of the appropriate amount of thinners to enhance
wetting, prevent foaming;
5, 35 degrees C or more construction, can be under the guidance of professional application and technical personnel to carry out safety testing, the appropriate amount to reduce the curing agent ratio, reduce the range of about 10%, or add the appropriate amount of slow dry water, the amount of addition should not exceed
25%;, the mix to be used up within 1-2 hours, as far as possible according to the amount of use of the deployment;
7, the main agent to be stirred well before use, matte paint mixture needs to be stirred evenly at regular
8 , unused products need to be sealed and stored;
9, the temperature is higher than 35 degrees C or humidity is greater than 85%, it is recommended to stop construction, try to avoid spraying construction during the highest temperature of the day, it is recommended that conditional furniture factory to add air conditioning and other cooling equipment .
, however, in the actual construction, the source of the hand sweat problem is often ignored, but also not easily detected. The author believes that the reasons are as follows:
A) sticking to the surface of the furniture sweat is the finger contact with the furniture produced, the area is small, not easy to be found, and related to the operation of the coating workers, with a certain degree of randomness, such as the above-mentioned cases of problems are spruce and local.
B) process, hand sweat caused different problems, thus increasing the difficulty of judgment. Usually, after the substrate sticks to the hand sweat, spraying the primer will cause running oil or de-layering, when the primer or finish paint is applied, the plate surface sticks to the hand sweat, easy to cause running oil, and the finish front plate has hand sweat, the finish will be flowering.
C) coating causes paint film running oil, de-layering and flowering factors, hand sweat is just one of them.
, how can we quickly determine the problem caused by hand sweat? Can be analyzed and tested from the following two points:
A) is usually caused by hand sweat running oil, de-layering and flowering, only appear in a small area of the plate surface, not the entire plate.
B) hand sweat caused by running oil, de-layering and hair flowers, the shape is close to the shape of the finger print.
, we found in the construction of hand sweat caused by running oil, de-layering and flowering phenomenon, how to deal with?
First of all, should stop the construction, and after removing the hand sweat pollution factors, the flowering plate surface with diluent scrubbing clean, and running oil, de-layering of the plate surface in the dry, should be polished flat, re-sprayed.
, from the root cause to avoid hand sweat pollution board, to do the following two aspects:
A) Wear disposable gloves or wire gloves or coated protective clothing during construction.
B) For larger work parts, when the replacement process needs to be handled, use the appropriate tools to avoid direct hand contact with the plate surface. For example: wooden doors in the coating, can be punched at both ends, with rebar inserted into the hole to make armrests, you can avoid handling, hands direct contact with the plate surface.
