The invention relates to the technical field of toothpaste, in particular to a traditional Chinese medicine composition for toothpaste, a preparation method of the traditional Chinese medicine composition, finished toothpaste and a preparation method of the finished toothpaste. The traditional Chinese medicine composition is prepared from the following traditional Chinese medicine components in percentage by weight: 10%-20% of embelia laeta, 20%-30% of alkali, 20%-30% of rhizoma zingiberis, 10%-20% of ferula asafetida and 10%-20% of cumin. Wherein the embelia laeta can eliminate various pathogenic bacteria in a human body and effectively play a role in tooth moth prevention; the alkaline flower is alkaline, can prevent acidic corrosion of teeth, has digestion and absorption effects, and is beneficial to digestion of food residues in the oral cavity; the dried ginger is warm in nature and has the effects of improving blood circulation of the oral cavity and removing ozostomia; ferula asafetida is warm in nature and can relieve undefined pain of whole teeth caused by the uplift disease (namely wind or qi in traditional Chinese medicine); cumin can eliminate gingival abscess; the five medicinal materials are matched to remove halitosis, prevent moths and acid, relieve raised teeth, eliminate swelling of gingiva and improve oral blood circulation.

The invention discloses a straight-stroke support which comprises an upper flange, a lower flange, a sleeve part and a driving walking part. The driving walking part comprises a driving sleeve, a main shaft, a fixing ring, a straight walking rod and a connecting end cover. The driving sleeve and the main shaft are connected in a thread mode. The driving sleeve is made of copper. The driving sleeve is fixed in the straight walking rod through threads. The driving walking part further comprises a pressing cover, a limiting ring, a pressing ring, a driving sleeve pressing block and a thrust ball bearing. The pressing cover, the limiting ring, the pressing ring and the driving sleeve pressing block are all made of cast iron STSi5R. According to the straight-stroke support, a valve and an actuator can be effectively connected, circle rotating is converted into straight line walking, gas etching, acid etching, water erosion and oxidation can be effectively avoided, vibration and noise are low, attractiveness and safety are achieved, environment is protected, and adaptability is high.

The invention discloses a protective agent of a pile head of a storage battery and a preparation method thereof. The protective agent comprises the following components by weight percent: 25%-35% of antioxidant, 10%-15% of mineral oil, 5%-10% of penetrating agent, 20%-25% of anticorrosive additive and 15%-25% of LPG (liquefied petroleum gas) propellant. When the protective agent is used, a package bottle is close to the sprayed position for spraying, and the proper spraying amount is applied. The protective agent can form a long-acting temperature-resisting film so as to protect the pile headof the storage battery, a charging clip and a circuit joint; the protective agent can prevent oxidation and maintain the good contact of the storage battery; the protective agent can prevent the acidic corrosion of the storage battery; and the protective agent can prevent instant impedance and voltage drop.

The invention relates to a steam condensate corrosion inhibitor for an industrial boiler. The corrosion inhibitor is prepared from the raw materials in percentage by weight: 5-10% of dodecylamine acetate or octadecylamine acetate, 60-80% of cyclohexane or morpholine, 3-10% of ethanediamine tetramethene sodium phosphate and 100% of distilled water or deionized water. The corrosion inhibitor can form a compact protective film on the surface of metal; remove carbon dioxide in condensate; and prevent the boiler from scaling when the boiler feed water hardness does not meet the standard and the like. The corrosion inhibitor provided by the invention has the characteristics of small addition of medicine, low water treatment cost, good corrosion effect and the like, and is easy to operate. The corrosion inhibitor is used for recycling steam condensate for the industrial boiler, and has a remarkable effect on energy conservation and emission reduction.
