Die Pflege einer Gusseisenpfanne ist ebenfalls einfach, erfordert aber einige grundlegende Schritte, um die Patina – die schützende Schicht, die sich im Laufe der Zeit bildet – zu erhalten. Nach dem Kochen sollten Sie die Pfanne gründlich abspülen und mit einem Tuch abtrocknen. Verwenden Sie nie Seife, da diese die Patina angreifen kann. Stattdessen genügt es, die Pfanne nach dem Abtrocknen leicht mit Speiseöl zu behandeln, um die Oberfläche geschmeidig zu halten.

  • 2: Clarification mechanism of coagulant

    Chemical coagulation is a process in which chemical agents (coagulants) are added to water treatment to make colloidal dispersion system destabilize and agglomerate. In the coagulation process, small suspended particles and colloidal impurities are aggregated into larger solid particles to separate particulate impurities from water, which is called coagulation clarification.

    After adding coagulant into water, colloidal particles and other small particles can be polymerized into larger flocs through the comprehensive action of mixing, coagulation and flocculation. The whole process of coagulation and flocculation is called coagulation.

    (1) Destabilization and condensation of colloids

    Adding electrolyte to water can compress the electric double layer and destabilize the colloid. The main mechanism is that the electric double layer of colloidal particles in water is compressed or neutralized by adding aluminum salt or iron salt coagulant. The coagulant and raw water are mixed rapidly and evenly, and a series of chemical reactions are produced to destabilize. This process takes a short time, generally about 1 min. Some cationic polymers can also play a role in the destabilization and condensation of colloids in water. These polymers have a long chain structure and positive charge in water. Their destabilization and condensation of colloids in water is due to the interaction of van der Waals force adsorption and electrostatic attraction.

    (2) Flocculation and formation of floc (alum)

    The particle size of the initial flocculate formed by colloid destabilization and coagulation in water is generally more than 1 m. at this time, Brownian motion can no longer push them to collide and form larger particles. In order to make the initial flocs collide with each other to form large flocs, it is necessary to input additional energy into the water to produce a velocity gradient. Sometimes it is necessary to add organic polymer flocculant into water, and the adsorption bridging effect of long chain molecules of flocculant is used to improve the probability of collision and adhesion. Flocculation efficiency usually increases with the increase of flocculate concentration and flocculation time.

    Compared with polyaluminum chloride, polyaluminum chloride has the advantages of high density, fast settling speed and wide pH adaptability; the coagulation effect is less affected by temperature than that of polyaluminum sulfate; however, when adding ferric salt, it should be noted that when the equipment is not in normal operation, the iron ions will make the effluent color, and may pollute the subsequent desalination equipment.

  • Polyvinyl butyral (PVB) is dissolved into 12 ~ 14% solution with ethanol and made into film. It is used for printing paper film of ceramic (or enamel) products. The fired ceramic (or enamel) patterns have bright color and smooth texture. The flower paper is characterized by convenient use, low cost, smaller than the original glue, greatly reducing the decal process and high color burning rate. At present, most porcelain factories in China have formed relatively formal production lines for standardized production. Therefore, the demand for PVB in the ceramic (or enamel) flower paper industry is increasing.

  • In a study published in the journal Toxicology, researchers examined the effects of exposing human colon cancer cell line (HTC116) titanium dioxide food additives in vitro. “In the absence of cytotoxicity, E171 was accumulated in the cells after 24 hours of exposure, increasing granularity and reactive oxygen species, inducing alterations in the molecular pattern of nucleic acids and lipids, and causing nuclei enlargement, DNA damage and tubulin depolymerization,” the scientists wrote. Researchers removed the additive from the culture, then examined the results 48 hours later. They found, “The removal of E171 was unable to revert the alterations found after 24 h of exposure in colon cells. In conclusion, exposure to E171 causes alterations that cannot be reverted after 48 h if E171 is removed from colon cells.”

  • One of the most significant impacts of TIO2 in factories is its role in photocatalysis. This process involves the acceleration of photoreaction in the presence of light and a catalyst—in this case, TIO2. By harnessing the power of sunlight or artificial UV light, TIO2 can break down organic pollutants into substances, playing a crucial role in environmental remediation efforts within industrial settings. This not only helps factories minimize their environmental footprint but also reduces the costs associated with waste treatment and disposal.
