Background

The active ingredients of the laundry detergent are mainly nonionic surfactants, and the structure of the laundry detergent comprises a hydrophilic end and an oleophilic end, wherein the oleophilic end is combined with stains, and then the stains and fabrics are separated by physical movement (such as hand rubbing and machine movement). Meanwhile, the surfactant reduces the tension of water, so that the water can reach the surface of the fabric, and the effective components can play a role.

The high-quality laundry detergent mainly has three standards: the higher the concentration, the less the amount used; the lower the viscosity, the more soluble; the less foam, the easier it is to rinse. The concentration is higher, and the use amount is more saved: high concentration, i.e. high active content; the viscosity of the laundry detergent is specially reduced, the fluidity of the laundry detergent is improved, and the laundry detergent is convenient to pour, pre-coat and dissolve; by adopting a foam control technology, the low-foam bleaching is easy, and the foam is basically bleached after one-time bleaching.

Therefore, in the production process of the laundry detergent, the concentration, viscosity and foam quantity of the laundry detergent need to be accurately controlled, so that the production quality of the laundry detergent is improved and ensured, and the waste of raw materials and the defective rate are reduced. The method comprises the following steps that sampling detection is required to be frequently carried out on the laundry detergent in different procedures, a sampler is required to be used in the process of sampling the laundry detergent, and the conventional laundry detergent sampler does not have a special sampler designed for the laundry detergent and is mostly common liquid samplers in the market; when the common liquid sampler is applied to the production process of laundry detergent, a plurality of disadvantages exist; for example, a laundry detergent sample cannot be drawn at a fixed point and height, and the drawn sample is easily contaminated by different layers of high laundry detergent; the laundry detergent is easy to generate a large amount of foam to enter a sampler under the action of external force in the extraction process, so that the sampling sample is influenced and the amount of the sampling sample is reduced; the concentration of the laundry detergent is higher than that of water, the thrown sampler is not easy to sink, and the time for sinking to a preset depth is long, so that the detection efficiency is influenced;
