3. Qualité du lavage Grâce à un contrôle précis des paramètres de lavage, comme la température, le temps et le dosage des produits chimiques, les systèmes de blanchisserie tunnel assurent un nettoyage en profondeur des textiles. Cela permet de prolonger la durée de vie des articles et de garantir leur propreté impeccable.

Previously, car washing was done using a manual+faucet+mop washing mode. It took a long time to wash a car, and many dead corners could not be cleaned thoroughly, which not only made people tired but also led to frequent complaints. Now that the automatic car wash machine is enabled, it not only saves time, manpower, and material resources, but also greatly improves the efficiency and cleanliness of the car wash.

Once you have a location, you’ll need the necessary equipment. The core of any car wash business includes high-quality pressure washers, vacuums, and water supply systems. Pressure washers come in various sizes and should be powerful enough to remove dirt and grime without damaging the vehicle’s surface. Additionally, you’ll need vacuum cleaners for both interior and exterior cleaning. It is wise to invest in industrial-grade equipment to ensure durability and efficiency.

In conclusion, investing in a car cleaning cart can transform your vehicle cleaning routine. By enhancing organization, improving efficiency, and promoting regular maintenance, a cleaning cart not only makes the process easier but also contributes to the overall longevity and appearance of your car. With everything you need at your fingertips, keeping your vehicle in top condition has never been more accessible. So, consider making this addition to your car care arsenal and enjoy the benefits of a cleaner, more organized cleaning experience.

Tlakové myčky jsou také velmi všestranné. Kromě mytí automobilů je můžete použít na řadu dalších aplikací, jako je čištění teras, zahradního nábytku nebo dokonce fasád domu. S různými nástavci a příslušenstvím je možné upravit tlak a množství vody podle potřeby, což z nich činí skvělý nástroj pro údržbu domácnosti.

Titanium dioxide in sunscreen

After oral ingestion, the absorption of titanium dioxide particles is low, however they can accumulate in the body, Maged Younes, chair of the European Food Safety Authority's expert Panel on Food Additives and Flavourings, said in a May 2021 statement.

The skin of an adult person is, in most places, covered with a relatively thick (∼10 μm) barrier of keratinised dead cells. One of the main questions is still whether TiO₂ NPs are able to penetrate into the deeper layers of the skin. The majority of studies suggest that TiO₂ NPs, neither uncoated nor coated (SiO₂, Al₂O₃ and SiO₂/Al₂O₃) of different crystalline structures, penetrate normal animal or human skin. However, in most of these studies the exposures were short term (up to 48 h); only few long-term or repeated exposure studies have been published. Wu et al.83 have shown that dermal application of nano-TiO₂ of different crystal structures and sizes (4–90 nm) to pig ears for 30 days did not result in penetration of NPs beyond deep epidermis. On the other hand, in the same study the authors reported dermal penetration of TiO₂ NPs with subsequent appearance of lesions in multiple organs in hairless mice, that were dermal exposed to nano-TiO₂ for 60 days. However, the relevance of this study for human exposure is not conclusive because hairless mice skin has abnormal hair follicles, and mice stratum corneum has higher lipid content than human stratum corneum, which may contribute to different penetration. Recently Sadrieh et al. performed a 4 week dermal exposure to three different TiO₂ particles (uncoated submicron-sized, uncoated nano-sized and coated nano-sized) in 5 % sunscreen formulation with minipigs. They found elevated titanium levels in epidermis, dermis and in inguinal lymph nodes, but not in precapsular and submandibular lymph nodes and in liver. With the energy dispersive X-ray spectrometry and transmission electron microscopy (TEM) analysis the authors confirmed presence of few TiO₂ particles in dermis and calculated that uncoated nano-sized TiO₂ particles observed in dermis represented only 0.00008 % of the total applied amount of TiO₂ particles. Based on the same assumptions used by the authors in their calculations it can be calculated that the total number of particles applied was 1.8 × 10¹³ /cm² and of these 1.4 x10⁷/cm² penetrated. The surface area of skin in humans is around 1.8 m²  and for sun protection the cream is applied over whole body, which would mean that 4 week usage of such cream with 5 % TiO₂ would result in penetration of totally 2.6 × 10¹⁰ particles. Although Sadrieh et al.concluded that there was no significant penetration of TiO₂ NPs through intact normal epidermis, the results are not completely confirmative.
