JW white (ultra high strength) fast hardening sulphoaluminate gelling agent
Classification:
Detailed introduction
JW white (ultra-high strength) fast-hardening sulphoaluminate gelling agent is under the strong support of relevant leaders and industry colleagues of the National Building Materials Science Research Institute, under the technical guidance of domestic well-known experts such as Professor Su Muzhen, former Vice President of the National Building Materials Institute, Professor Cui Qi, Dr. Li Qinghai, Senior Engineer Zhang Qiuying, etc, it is a high-tech product with the performance of sulphoaluminate gelling agent, pure aluminate gelling agent and white silicate gelling agent, which is independently developed by the company's technical personnel on the basis of summarizing and absorbing the performance indexes of fast-hardening sulphoaluminate gelling agent, pure aluminate gelling agent and white silicate gelling agent.
Performance characteristics:
JW white (ultra-high strength) fast hardening sulphoaluminate gelling agent, with high purity whiteness, its whiteness value of more than 90 and bright color, far superior to the domestic high-quality white silicate gelling agent.
High early strength: it not only absorbs the performance characteristics of fast hardening sulphoaluminate gelling agent, but also significantly enhances the hourly strength, the late strength can continue to increase, and the setting time can be flexibly adjusted according to customer needs.
It has micro-expansion performance, low alkalinity, no radioactivity and high stability.
Main purpose:
JW white (ultra-high strength) fast hardening sulphoaluminate gelling agent is mainly used in GRC industry high-grade architectural jewelry, color cultural stone, carving crafts, urban garden products, building exterior wall products and configuration of various colors of gelling agent products.
Technical indicators:
The corresponding indicators in JC/T2601-2021 "White sulphoaluminate cement" shall be implemented and better than the standard requirements.
Hunter whiteness: not less than 75.
Specific surface area: not less than 350 m2/kg.
Setting time: initial setting is not less than 20min, final setting is not more than 180min, can be adjusted according to user requirements.
The strength grade of Jw white (high strength) fast hardening sulphoaluminate gelling agent shall not be lower than the data in the table.(Strength index in MPa)
| Model | Whiteness | Strength grade | Bend strength (MPa) | Compressive strength (MPa) | ||||
| 1d | 7d | 28d | 1d | 7d | 28d | |||
| 90 | ≥ 90 | I | 4 | 5.5 | 7 | 30 | 42.5 | 46 |

| 80 | ≥ 80 | I | 4 | 5.5 | 7 | 30 | 42.5 | 46 |
| II | 7 | 8 | 8.5 | 55 | 72.5 | 76 | ||
| 75 | ≥ 75 | I | 4 | 5.5 | 7 | 30 | 42.5 | 46 |
| II | 7 | 8 | 8.5 | 55 | 72.5 | 76 | ||
Note:
The product must be used in the process of using the container, agitator clean. It is best to use white quartz sand, sand and water and other additives must be pure and free of impurities and must not be mixed with any other varieties of gelling agent, so as not to affect the whiteness and strength.
The product is a low water gelling agent, should be stirred for 3-4 minutes, timely construction, gelling agent mortar does not allow secondary mixing.
Packaging and storage:
This product is 25kg or 50kg with lined moisture-proof sealed plastic woven bag packaging.
When stored, should be placed in a cool, dry place, prevent moisture and damage.
Under normal circumstances, the shelf life is 45 days. If it expires or is found to be damp and hard, it should be re-tested before use.
During storage, it shall not be mixed with other gelling agents.
