products are absorbing advanced technology developed at home and abroad efficient, moisture-proof, impermeable, plugging material, is also an excellent bonding material. the materials were quick-setting type (mainly for anti-seepage plugging) and retarding type (mainly used for moisture-proof, seepage) are two-component gray powder.
(1) non-toxic, tasteless, non-flammable can be used for drinking water projects.
(2) welcome, back water can be construction, construction convenience.
(3) water construction, moisture, impermeability, rapid plugging.
(4) plugging solidification time optional, waterproof adhesive to complete a strong bond, impermeability and compression.
(5) combined with the matrix into a whole, not aging, good water resistance.
uses: mainly used in underground buildings, walls, trenches, pools, toilets, etc. waterproof, anti-seepage leakage.

construction technology
construction tools
1. clean up the basal tools: shovels, chisels, hammers, wire brushes, brooms, rags;
2. weigh ingredients ingredients tools: buckets, scales, mixing bowl (barrels), blender;
3 plugging tools: different diameter sticks;
4 feeding tools: scraper, trowel, pressure child;
5 conservation tools: sheng basin, water jet, brush;
2. no seepage surface construction
base treatment: the base surface must be fully moist
saturated (but no water). and requires a solid clean, smooth (uneven place with cement mortar or plugging ling leveling).
scratch method: (if the second layer has no water after the third layer can not do)
ingredients ratio: powder water = 1: 0.25 ~ 0.35 dosage 1.2kg / m2
the total amount of material: do two .2.4kg / m2 to do three: 3.6kg / m2
thickness: (b) do two: 1.5mm to do three: 2.2mm
use: pool, basement toilet, bath and other waterproof.
ingredients: no seepage surface construction should choose yuyuan brand retarding solid plugging ling. the material powder = 1: 0.25 ~ 0.35 mix into putty.
feeding:
according to "scratch wiping law" provisions of the material, first with a trowel or scraper on the first layer of material to be cured after coating (hand pressure without fingerprints) to wet (but can not have water); reuse trowel or scraper on the second layer of material. when loading, to be slightly harder and back and forth to make it dense and pay attention to overlap, according to the specific project to master.
moisturizing conservation:
after the coating is hardened, immediately moisturizing conservation to prevent chalking the first maintenance should be careful not to damage the coating. maintenance 2-3 days. maintenance methods for the spray, cover wet material, coating liquid care.
in special damp places. or in the coating to do the protective layer or paste the block. can save conservation.
3. seepage surface construction
base treatment: the base surface must be solid, clean, smooth and full moisture to saturation (but no water. unevenness with cement mortar or plugging ling leveling). water seepage is serious. ingredients: seepage surface construction should use quick-setting plugging spirit. the material according to powder: water = 1 0 25 ~ o 35 mix into putty.
feeding:
according to the provisions of the "scraping wiping method" if the substrate surface water seepage serious hit the bottom of the water channel buck. and then top-down construction of concrete practices with a dry cloth to dry the base quickly trowel on the first layer of material, if if there is water leakage, wait until the coating is hardened (hand pressure does not leave fingerprints) to spray it wet (but can not have water); then trowel or scraper if the second layer of material still seepage. do not leak, and finally blocked by blocking method diversion hole. when feeding to a little hard and back and forth to make it dense and pay attention to overlap. according to the specific project to master each layer of material is about 1-1.5kg / m2 baohe conservation: to be coated hardening, immediately moisturizing conservation to prevent chalking. the first conservation should be careful not to damage the coating, conservation 2-3 days , conservation methods can be: spray cover wet material, coating liquid care. in special humid or coating to do the protective layer or paste the block can save conservation.
4. leakage construction
lost workmanship: ingredients ratio: powder: water = 1: o.25 1: 0.3 ~ 0.35
scope of application: leakage plugging.
feeding:
according to the shape of the hole plugging slightly smaller than the size of the hole into the dough, place for a while (to pinch a sense of hardiness is appropriate) into the leakage, and with wooden stick backlog, light hit to squeeze around to the circumference. then leak around the mouth about 10cm with a layer of trowel on the scraping material, plugging before the hole may have to leaking parts of the best waterproofing. after the coating has a certain hardness and then plugging, or water may seep from the surroundings.
wet curing:
after the coating is hardened, moisturizing and curing should be carried out immediately to prevent chalking. the first curing should be careful not to damage the coating. the curing methods may include spraying water, coating wet materials, coating liquid and so on. in special humid place, or in the coating to do the protective layer or paste the block, eliminating the need for conservation.
after construction inspection, acceptance method
after construction, all parts of the whole project should be carefully inspected, especially the weak links, and the cause of the problems should be found out and repaired promptly. for wet environments, if there is still no water on the coating surface due to construction quality problems, moisture condensation should be taken into account, this phenomenon will disappear when the scene is dry.
product storage and use precautions
product storage
the product is double-layer plastic bag vacuum packaging, specifications for the 1kg and 5kg, carton packaging, net weight 20kg.
the material is damp and should be stored in a dry place. shelf life of one year.
2. major issues
construction under the summer hot sun, need humidification conservation, winter construction below -5 ℃ need to add 1-3% by weight of powder material sodium nitrite, rain construction, to prevent rain washed water layer.
