1. Introduction to quick cracking asphalt emulsifier
Quick cracking asphalt emulsifier is a material used for the preparation of asphalt mixtures and road construction. It forms lotion by mixing asphalt and emulsifier. After construction, lotion quickly separates from water to separate asphalt from lotion, so as to achieve rapid solidification. Quick cracking asphalt emulsifier (KL-2) is a cationic quick cracking asphalt emulsifier with excellent asphalt emulsification ability, high cost-effectiveness, and no need for acid adjustment. It has a wide applicability to asphalt and can be used for the production of PC-1-2, PCR, SBS modified emulsified asphalt, and high viscosity modified emulsified asphalt.
2. Characteristics of quick cracking asphalt emulsifier
(1) Fast solidification: The fast cracking asphalt emulsifier has a fast solidification speed and can completely solidify within 30 minutes.
(2) Firm structure: the cured asphalt structure is firm, with good water resistance and aging resistance.
(3) Convenient construction: Convenient construction, easy operation, and low requirements for the construction environment.
(4) Low sound: Due to its fast solidification speed, the sound is relatively low during the construction process.
3. Usage method of quick cracking asphalt emulsifier
Add the measured product to hot water at 60-70 ℃ and stir until completely dissolved before use.
4. Applicable process of fast cracking asphalt emulsifier
Adhesive layer, gravel sealing layer, precision surface, ultra-thin cover
5. Main technical indicators of fast cracking asphalt emulsifier
(1) Appearance: White paste like substance
(2) Active ingredient content: 50%
(3) PH value: 2.0~5.0
(4) Dosage: 0.6% -0.8% (physical addition amount, base asphalt) 1.2% -1.5% (physical addition amount, modified asphalt)
(5) Packaging: 100kg or 50kg/drum
6. Application scenarios
(1) Early repair: used to repair small cracks on the road surface in the early stage, avoiding their expansion and causing larger road problems.
(2) Emergency repair: In emergency situations, fast cracking asphalt emulsifiers can quickly repair and restore road traffic.
(3) Old road surface renovation: used for the renovation of old road surfaces to improve their load-bearing capacity and service life.
7. Difference from slow cracking asphalt emulsifier
The main difference between fast cracking asphalt emulsifier and slow cracking asphalt emulsifier lies in the speed of emulsion breaking. The fast breaking asphalt emulsifier has a fast demulsification speed and is suitable for scenarios that require rapid solidification; However, slow cracking asphalt emulsifiers have a slower demulsification speed and are suitable for scenarios that require a longer solidification time.
