Winter comes, what are the problems need to pay attention to the construction joints?

Most of our country will enter the winter, and low winter temperatures in various areas, big temperature difference between day and night, storage and use of the seam an agent will bring great influence.

in order to guarantee the quality of products and the construction effect, now the winter storage, construction points for attention to the following:

storage and construction temperature requirements

construction temperature requirements above 5 ℃

in order to ensure the effective curing seam an agent, the seam an agent construction requirements in more than 5 ℃. New house no heating, can use the electric heater, in order to improve the indoor temperature of construction environment.

conditional construction site, can open air conditioning, appropriately increase temperature to the construction site.

when temperature is too low to product appropriate heating

( 1) Low temperature will make higher viscosity of epoxy resin, and force sex, even with saving glue guns out of also can cause AB components mixed uneven, resulting in a local it or the insufficient hardness.

so, beauty advice before construction seam an agent into warm hands treasure or hot water ( Must be sealed) Preheating, preheat temperature not more than 50 ℃, time control in 10 & ndash; 15 minutes.

preheating time not too long, the temperature is too high will make the seam an agent to produce flow phenomenon. Preheat the seam an agent to the discharging mouth down, bottom up.

（ 2) After low temperature, construction of colloid solidification speed will slow down, suggest the Windows closed, at the same time open central heating or air conditioning indoor temperature ascending. If no heating or air conditioning, heating blow ram could be used directly to blow colloid to speed up the curing.

（ 3) The temperature below 5 ℃ shovel glue ( Clean up) Have the embrittlement ( Rubber strip brittle, bad spade) Phenomenon, it is recommended that: one is to confirm whether colloidal cured;

2 it is to will improve, indoor temperature is warm, open air conditioning or heating as you. Confirm the temperature is higher than 5 ℃ to shovel glue and clearing in an hour.

if MAO brick, will first put crepe paper or painted beautiful seam wax.

stored at 5 ℃ temperature above

winter beautiful seam an agent to guarantee in 5 ℃ - storage temperature Between 30 ℃. （ Special note: can't storage temperature of the instant change and seam an agent, such as below 5 ℃ ( 0 degrees Fahrenheit or 0 degrees) Quickly rose above 50 degrees, this will make the inside seam an agent of epoxy resin crystallization reaction ( Into small granular solid) , the beauty of crystallization seam an agent can only scrap cannot be used for construction. ）

seam floor heating is more beauty to do

the north use terrestrial heat, more more beautiful seam to do. Because they don't do the seam, floor heating of the heat from the crack out at, and out of the dust, bacterium.

floor heating conditions of construction:

( 1) Can under the condition of the construction of floor heating, just pay attention to the local area near the heating machine pipe temperature is exorbitant, can produce some bubbles. Under the condition of indoor warm can turn off the heat for a while, with high local temperature area temperature drop after sizing, complete sizing again after heating. This construction can avoid the generation of air bubbles.

（ 2) In floor heating under the condition of scraper glue should pay attention to avoid pulling the inside of the slit strip. Because warm conditions, even if the colloid solidification, but not to gel hardness, so easy to spin out the cranny strip.

construction environment humidity requirements

doors and Windows construction to avoid crack near damp

the north the weather is dry, but because congress temperature difference between indoor and outdoor humidity near Windows, doors and Windows construction, near to see gap, avoiding damp.

to keep dry and indoor construction environment

the south winter indoor damp fog, humidity is bigger, dry construction to maintain indoor environment. Available air conditioning dehumidification.

gap to dry clean environment

the seam an agent construction requirements gap environment dry clean and no water vapor, ground, metope have moisture water, must not force construction, so as to avoid the white color change after seam an agent construction, again after with aperture of moisture also can use hair dryer dry construction.

about the ventilation requirements of

the north not to open doors and Windows construction ventilation to avoid cracking

the cooling air in the north is too heavy, don't open a window ventilated before and after the construction to avoid the slit cracks formation, also will increase the time of curing.

the south construction don't open a window ventilated to avoid moisture absorption

winter of southern moisture, do not open a window ventilated, before, during, and after the construction to avoid the seam an agent in curing absorb moisture, in white, the color becomes shallow.

in the winter is coming, are you planning to stay in this perfect beauty complete ceramic tile seam in winter? Hope the above introduction will be helpful to you!
