Product Description:Dental Block Abrasion Tester, Dental Block Staining Instrument, Toothbrushing Evaluation System Product Introduction<img src="https://img-i-album.toocle.com/view/2025/05/31/30/683a65466cd30.jpg" style="max-width:100%;"/>Since the invention of toothpaste, cleaning teeth has always been its primary and most fundamental function. This cleaning action is largely achieved through abrasives in the toothpaste formulation. Common abrasives used in toothpaste today include silica, calcium carbonate, and others. The mass fraction of abrasives in toothpaste formulations typically ranges from 15% to 50%. During brushing, these abrasives are the main factor in mechanically removing dental plaque and stains. However, using toothpaste with excessively high abrasiveness can lead to wear on the hard tissues of the teeth while cleaning.The ISO 11609 method uses bovine tooth samples as in vitro experimental materials. These samples are subjected to reciprocal brushing on an abrasion tester/brushing machine to evaluate the degree of tooth wear caused by toothpaste.Multiple instruments have been developed to assess the abrasiveness of toothpaste, toothbrushes, tooth powder, and teeth whitening products on teeth. Based on this, various dental blocks have been created for characterizing tooth wear.Dental Block Abrasion Tester, Dental Block Staining Instrument, Toothbrushing Evaluation System RS-01  is designed and developed in accordance with T/COCIA7-2020, GB/T43576-2023 laboratory evaluation of toothpaste efficacy in removing extrinsic stains, and GB/T35832-2018 toothpaste abrasiveness testing method requirements. It is a standard-designed testing instrument.Dental Block Abrasion Tester, Dental Block Staining Instrument, Toothbrushing Evaluation System RS-01 Main ParametersInstrument Name:Dental Block Staining InstrumentMeasurement Units: r, r/min, ℃Measurement Accuracy: 0.2% F.STest Modes: Time-based; Rotation-basedClamping Size: 0mm - 13mmSample Capacity: 200 piecesHeating Method: Top heatingData Storage: 2000 setsDimensions: 700 (L) × 390 (B) × 501 (H) mmWeight: Approximately 20kgPower Supply: AC220V±22V, 50HzOptional Configurations: Custom fixtures according to customer requirements<a href="https://www.paratronixcn.com/products/show-147.html" target="_blank">https://www.paratronixcn.com/products/show-147.html</a> more>

Product Description:PVDF Screw Manufacturer, Custom Processing of PVDF Screws.PVDF is a fluoroplastic product, an abbreviation for poly(vinylidene fluoride), primarily referring to the homopolymer of vinylidene fluoride or copolymers of vinylidene fluoride with small amounts of other fluorinated vinyl monomers. It combines the characteristics of both fluororesins and general-purpose resins. In addition to excellent chemical corrosion resistance, high-temperature resistance, oxidation resistance, weather resistance, and radiation resistance, it also possesses special properties such as piezoelectricity, dielectricity, and thermoelectricity. It is currently the second-largest product in terms of production volume among fluoroplastics, with a global annual production capacity exceeding 43,000 tons. The applications of polyvinylidene fluoride (PVDF) resin are mainly concentrated in three major fields: petrochemicals, electronics and electrical engineering, and fluorocarbon coatings. PVDF resin is one of the most important raw materials for fluorocarbon coatings. Fluorocarbon coatings prepared from it have evolved to the sixth generation. Due to the ultra-high weather resistance of PVDF resin, these coatings can be used outdoors for extended periods without maintenance, making them widely applied in power plants, airports, highways, high-rise buildings, and more. Additionally, PVDF resin can be blended with other resins for modification, such as PVDF resin blended with ABS resin to produce composite materials, which are extensively used in construction, automotive decoration, household appliance casings, and more. more>

Product Description:       Combination screws are generally divided into two-piece combination screws and three-piece combination screws. Two-piece combination screws consist of a screw rod combined with either a spring washer or a flat washer; the washers can also be square washers or serrated washers. Three-piece combination screws refer to a connecting component consisting of a screw rod paired with a flat washer and a spring washer.          Common materials for combination screws include iron and stainless steel. Iron combination screws require surface treatment after production, such as electroplating. Common electroplating finishes include white zinc, nickel, color zinc, blue zinc, black oxide, black zinc, black nickel, etc. Electroplating treatments are divided into standard electroplating and environmentally friendly electroplating. The commonly used stainless steel material is SUS304. After production and processing, it can be cleaned and passivated if there is a requirement for salt spray resistance exceeding 48 hours.     Common reference standards for three-piece combination screws: 1. GB/9074.13 (Cross recessed hexagon head bolts with spring washers and flat washers combination)  2. GB/9074.17 (Hexagon head bolts with spring washers and flat washers combination)   3. GB/9074.4 (Cross pan head with spring washers and flat washers combination) 4. GB/9074.8 (Cross small pan head with spring washers and flat washers combination) 5.

Product Description:       Hexagon socket head cap screws, commonly referred to in the industry as hex socket bolts, cup head screws, or hex socket screws, feature a cylindrical head with an internal hexagon socket. The head socket can also be designed as an internal梅花槽 (Torx), cross slot, or flat slot. Common materials used in screw production include iron and stainless steel. Iron material is also known as carbon steel, which is categorized into the following types: low carbon steel, medium carbon steel, high carbon steel, and alloy steel. Commonly used stainless steel materials include: SUS201, SUS304, SUS316, and SUS410.Surface treatment of screws varies depending on the material. Stainless steel materials are typically only cleaned to maintain their natural appearance. If there are salt spray (special anti-corrosion) requirements, passivation treatment can be applied later to enhance corrosion resistance. Surface treatment for iron materials generally involves electroplating, which is divided into standard electroplating and environmentally friendly electroplating. Common electroplating materials include: white zinc, white nickel, black oxide, black zinc, black nickel, blue zinc, and colored zinc.       Our company specializes in the production and sale of various precision screws, electronic screws, toy screws, and custom non-standard screw processing using materials such as SUS304, 316 stainless steel, and carbon steel.
