Q&A about Magnesium Chloride Hexahydrate Products

Today, Yuze, your magnesium chloride supplier, answers frequently‑asked questions from customers in Q‑and‑A format.

Q1: Can we judge product quality only by appearance and colour?

No. Some magnesium chloride hexahydrate products go through bleaching treatment during manufacturing. Therefore, appearance is only one reference factor and cannot fully reflect the real quality of magnesium chloride hexahydrate.

Key factors for judging magnesium chloride hexahydrate quality:

1.  Raw materials and production processes. Impurities such as iron, sulphates, sodium salts and calcium from brine or synthetic feedstock set the baseline quality. Some magnesium chloride supplier adopt by‑product processes followed by bleaching, so visual appearance alone cannot determine quality.

2.  Effective content. The main content of magnesium chloride hexahydrate directly affects downstream application performance.

3.  Aqueous‑solution clarity. Sediment and floccules in solution represent water‑insoluble matter, which has a major bearing on product quality.

4.  Heavy‑metal and fluoride indexes. Some magnesium chloride hexahydrate looks good visually yet fails key parameters, for instance excessive heavy metals or fluoride ions for wastewater treatment.

5.  Testing and quality control. Professional magnesium chloride suppliers conduct batch‑by‑batch laboratory testing to guarantee consistent specifications across shipments.

In summary, quality should not be evaluated based on a single indicator. The reliable approach is to inform your magnesium chloride supplier of your end‑use and critical parameters. Review factory test reports or third‑party inspection certificates, and request samples for re‑testing.

Q2: Why are 46% magnesium chloride flakes widely used?

46% magnesium chloride flakes represent the theoretical standard content for magnesium chloride hexahydrate. They fit most working conditions without extra formula adjustment and feature great versatility. 46% magnesium chloride white flakes have well‑controlled impurities and clear aqueous solutions, meeting strict requirements for export orders.

At a 46% magnesium chloride flakes factory, flake‑form products are directly shaped during production. Powder and granular grades require further crushing and re‑compression from base flakes, adding processing and labour costs. Hence 46% magnesium chloride flakes deliver excellent cost‑performance at 46% magnesium chloride flakes factories.

Additionally, compared with powder or granular 46% magnesium chloride, 46% magnesium chloride flakes are less prone to moisture‑induced caking and allow longer storage under identical conditions.

Q3: Can high‑quality 46% magnesium chloride flakes be universally applied across all industries?

They can be used in other industries for emergency purposes but may deliver sub‑optimal performance for long‑term application, since different industries prioritise different properties.

Take coal washing as an example: 46% magnesium chloride flakes are used for sulphur removal and fire prevention. High‑quality 46% magnesium chloride flakes work fine for sulphur removal yet perform poorly for coal fire suppression. High‑grade products produce clear solutions, whereas lower‑grade material provides better adhesion onto coal surfaces. It absorbs moisture from ambient air to form a protective layer; when fire occurs, it releases chlorine‑containing gas to suppress smoke and reduce smoke hazards. For coal‑washing applications, higher solution viscosity yields better practical results.
