Daily maintenance of wheels and what to pay attention to - Dhwheel.com

  1. Don't use detergent indiscriminately Maintaining wheels is the same as maintaining a car. Many household detergents and dishwashers commonly used on the market are basically too strong for the surface of the wheel hub due to their alkaline or acidic nature, which will cause chemical reactions on the surface of the  wheel hub  and lose their luster. The relationship is beautiful. Be careful when using. You can choose a little neutral soapy water to rinse. 2. Do not wash the wheels when they are hot When the hub temperature is high, it should be cleaned after cooling. Do not use cold water to cool down, this will damage the wheel hub, and even cause deformation of the brake disc, affecting the braking effect. 3. Clean the wheels clearly Well-cleaned wheels should be cleaned with neutral soapy water and wiped with a soft cloth at the same time. After cleaning, the surface of the wheel hub should be coated with corrosion-resistant products to maintain the surface brightness. If th

Enhancing Construction Material Quality with Defoamers

  In the construction materials industry, foam control is vital for producing high-quality, durable products. Foam often forms during the mixing and application of materials such as concrete, plaster, adhesives, and coatings. If not properly managed, foam can lead to air entrapment, reduced product strength, uneven surface finish, and higher production costs. Defoamers, or   anti-foaming agents , play a crucial role in preventing these issues, making production smoother and resulting in superior end products. Foam Challenges in Construction Materials Foam can disrupt multiple stages of the production process. In concrete mixing, for instance, foam can create voids, weakening the final structure. Similarly, in adhesives, entrapped air can lead to bond failure and poor application. For plaster and coatings, foam affects texture and appearance, resulting in an uneven or rough finish. These challenges highlight the need for effective foam management to ensure product reliability and durabi

The Role of Defoamers in Optimizing Pulp & Paper Production

  Foam control is a critical aspect of the pulp and paper industry, where efficiency and product quality are highly dependent on smooth production processes. Foam can form at several stages, especially during pulping and washing, leading to operational inefficiencies and increased production costs. By incorporating   defoamers , producers can reduce downtime, minimize waste, and improve the quality of both pulp and paper products. Foam Challenges in Pulp and Paper Processing In pulp and paper production, foam is often created by the interaction of pulp fibers, chemicals, and air within the processing tanks. Left uncontrolled, this foam can reduce tank capacity, slow down production, and even lead to spills. Foam buildup also impacts water quality in the recycling systems and can disrupt the effectiveness of water treatment, making foam control essential for meeting environmental and operational standards. How Defoamers Enhance Efficiency Defoamers work by breaking down bubbles and rele

  In the water treatment industry, foam management is crucial for maintaining smooth operations and high-quality standards. Foam forms when air, solids, and chemicals mix, especially in aeration tanks, wastewater systems, and effluent processes. Uncontrolled foam can lead to clogging, reduced capacity, contamination risks, and increased maintenance costs.   Defoamers , or anti-foaming agents, play an essential role in controlling foam, helping facilities operate efficiently and consistently. Defoamers in Key Water Treatment Processes Defoamers work by breaking down surface bubbles, which prevents foam from disrupting various stages of treatment. In aeration tanks, for example, defoamers ensure optimal oxygen transfer, which is critical for biological processing. In wastewater treatment, defoamers prevent foam buildup, maintaining a steady flow and reducing risks of overflow or clogging. During effluent discharge, defoamers reduce foam formation, ensuring that treated water meets clarit

World Stroke Day | "Wind" risk in platelet activation early warning

  World Stroke Day is observed on October 29 to underscore the serious nature and high rates of stroke, raise awareness of the prevention and treatment of the condition, and ensure better care and support for survivors. Stroke and platelet function Stroke refers to an acute cerebrovascular disease caused by the sudden rupture of blood vessels in the brain or the sudden interruption of blood flow to the brain. Hemorrhagic stroke, caused by a ruptured blood vessel in the brain, and ischemic stroke, caused by disruption of blood flow to the brain, are the two main types of stroke. Among them, ischemic stroke, also known as cerebral infarction, includes cerebral thrombosis and cerebral embolism, accounting for 85% of strokes. Platelet activation is the main mechanism of thrombosis and atherosclerosis. Activated platelets interact with various leukocytes such as monocytes, neutrophils, dendritic cells, and lymphocytes to trigger cell-to-cell signal transduction, resulting in thrombosis and

  Major risk factors for cardiovascular disease Hypertension: one of the main controllable risk factors, accounting for 50% of cardiovascular disease morbidity and 20% of deaths, but the awareness rate is only 46.9%, and the blood pressure control rate is even lower to 15.3%. Dyslipidemia: Studies have shown that the awareness, treatment and control rates of dyslipidemia in ≥ 18-year-olds need to be improved. Diabetes mellitus: It is an independent risk factor for cardiovascular disease, and once ASCVD occurs in diabetic patients, its lesions are diffuse and complex, and the prognosis is poor.   The role of biomarkers in cardiovascular risk assessment cTn:  cTnI and cTnT as key markers in the rapid diagnosis  of acute myocardial infarction, and their sensitivity and specificity are higher than those of traditional CK-MB and myoglobin detection. With the improvement of the accuracy of the detection technology, very low concentrations of cTn can be detected in 50%~96% of asymptomatic ind

Clinical application of procalcitonin (PCT) in the emergency department

  Infectious diseases are one of the common diseases in the emergency department, and the systemic inflammatory response syndrome caused by infection is the most fundamental pathophysiological change in sepsis. Due to the complexity of the systemic inflammatory response, there are no ideal diagnostic, stratification, prognostic tools, and effective treatment options. A number of studies have demonstrated that the pathophysiology of early sepsis is functional and reversible. Therefore, early and accurate diagnosis and monitoring of sepsis is one of the decisive factors in improving prognosis. Procalcitonin (PCT) has a good association with infection and sepsis and has been recommended for the diagnosis, stratification, treatment monitoring, and prognostic assessment of bacterial sepsis. 1 Introduction to the PCT 1.1 The main biological effects of PCT There is no clear conclusion on the biological effects of PCT, and the main biological effects are: the role of secondary inflammatory fac
