In golden October, the whole nation celebrates together. Californium Curium joins you in marking the 77th anniversary of the Republic: the origin of National Day and three little-known facts, the journey from 1949 to 2026, and festive greetings from all our colleagues.

The world's first hyperdispersant was launched by Shanghai Shijin Industrial Co., Ltd. & Dongguan Californium Curium New Material Technology Co., Ltd.: all experiments were completed in 2009, and the R1800 series was launched in 2010. Measured against the hyperdispersant category, it was about 1~3 years ahead of all peers worldwide (meaning hyperdispersant, not ordinary dispersant). The article provides supporting materials and scope boundaries that can be verified item by item, and explains why "hyperdispersant" and "dispersant" must not be treated as the same thing. Every figure comes from official data.

Californium Curium's open product data API is intended for customer systems and intelligent agents: no registration and no key are required; it supports read-only queries of public products and allows one message to be submitted on behalf of a customer. This article provides the parameter constraints for the 3 business endpoints, the verified response structures, the trigger conditions and handling recommendations for 8 error codes, the call pacing and cache policy, and the process constraint that "customer consent must be obtained before submission".
