1. Introduction to quick setting asphalt emulsifier
Quick setting asphalt emulsifier is a chemical additive that can quickly break emulsified asphalt (asphalt separates quickly from water), mainly used in projects that require rapid molding and short-term open traffic, such as prime coat, adhesive layer, surface treatment, etc. Its core feature is rapid solidification after construction, shortening maintenance time, and suitable for efficient road construction and repair.
Quick setting 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 setting 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 setting 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 setting asphalt emulsifier
Add the measured product to hot water at 60-70 ℃ and stir until completely dissolved before use.
4. Applicable process of fast setting asphalt emulsifier
Adhesive layer, gravel sealing layer, precision surface, ultra-thin cover
5. Main technical indicators of fast setting 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 setting asphalt emulsifier
The main difference between fast setting asphalt emulsifier and slow setting asphalt emulsifier lies in the speed of emulsion breaking. The fast setting asphalt emulsifier has a fast demulsification speed and is suitable for scenarios that require rapid solidification; However, slow setting asphalt emulsifiers have a slower demulsification speed and are suitable for scenarios that require a longer solidification time.
