Shield foaming agent is used for soil conditioning in EPB tunnelling. The foam solution (agent + water) is mixed with compressed air in a foam generator to produce fine, stable foam,

Shield dispersant is a chemical additive that prevents clay clogging (mud cake formation) on the cutterhead and in the excavation chamber during tunnelling in cohesive ground. In clay

Kenixiao (Clay Shield Filling Material) is an external filling material dedicated to shield tunnelling, composed of synthetic calcium-based clay minerals (modified inorganic calcium carbonate + calcium cellulose)

The Triazine H2S Scavenger is a water-soluble chemical with hexahydro-1,3,5-tris(hydroxyethyl)-s-triazine as the primary active ingredient, specifically designed for H2S removal during oil and gas production

The Triazine Biocide shares the same active ingredient as the H2S scavenger — hexahydro-1,3,5-tris(hydroxyethyl)-s-triazine (CAS 4719-04-4) — but serves a different purpose. As a biocide,

The crude oil demulsifier is a high-molecular-weight polyether nonionic surfactant polymerized from propylene oxide (PO) and ethylene oxide (EO) using polyamines, polyols, diepoxides and various resins as initiators.

The corrosion inhibitor uses oleic acid imidazoline as the primary active ingredient, compounded with thiourea derivatives and alkynol synergists. The polar groups (N, O atoms) in the imidazoline molecule adsorb onto the metal surface,
