Import Ferrochrome Lignosulfonate — Buy in Bulk from Supplier in China

Ferrochrome Lignosulfonate supplied by Mudanjiang Honglin Chemical Co., Ltd. is a dark brown powder used as a drilling‑fluid additive. The material is insoluble to water at less than 2.5 % and contains moisture below 8.5 %. Calcium sulfate impurity is limited to under 3.0 %, while total iron ranges from 2.5 to 3.8 % and total chromium from 3.0 to 3.8 %. Particle size analysis shows that material passing a 0.66 mm sieve contains less than 3.0 % oversize.

Lignosulfonate grades with similar composition are common in the oil‑field sector, where moisture levels between 5 and 9 % are typical to maintain stability. The iron‑chromium ratio of roughly 1 : 1 is standard for effective viscosity control in both fresh and salt water muds. Typical commercial products also meet a calcium sulfate ceiling of 3 % to avoid scale formation. The fine‑particle profile of this grade supports rapid dispersion and consistent thinning performance.

In practice the product is added to drilling fluids at 0.5 to 1.0 % by weight to keep the pH between 9.5 and 10.5 and to achieve viscosity reductions of 85 % in fresh water mud at 20 °C and 70 % in salt water mud at 25 °C. It is packaged in sealed paper‑plastic valve bags weighing 25 kg each, which facilitates bulk handling for importers. Buyers should confirm the minimum order quantity, Incoterms and payment conditions directly with the supplier before placing an order. The material remains effective at temperatures up to 150‑160 °C, making it suitable for high‑temperature drilling operations.

Mudanjiang Honglin Chemical Co., Ltd. is located at No. 6 Xinlin Road, Aimin District, Mudanjiang, Heilongjiang Province, China, postal code 157011. The company is listed with a harbour‑level trust tier on the platform, but its response rate is currently recorded as 0 % with no average response time. Its official address places it in a region known for chemical manufacturing and access to major transport corridors.

The firm offers Ferrochrome Lignosulfonate in 25 kg sealed paper‑plastic valve bags, targeting customers in the drilling‑fluid market. No additional certifications or capacity figures are disclosed in the listing, so interested importers should request laboratory test reports and confirm compliance with relevant industry standards.
