摘要:
Provided is a method of preparing a vinylchloride-based resin. The method includes adding to a vinylchloride-based latex an acid, preferably, 1-7 parts by weight of the acid based on 100 parts by weight of a solid of the vinylchloride-based latex; optionally, incubating the resultant mixture at a temperature of 30˜60° C. for 30 minutes to 3 hours; and drying the mixture. Therefore, it is possible to reduce the viscosity of a vinylchloride-based plastisol, thereby improving the processability of the plastisol.

摘要:
A heat exchanger washing device includes a wash water storage chamber to store wash water in a case, a wash water injection chamber to jet the wash water stored in the wash water storage chamber to a heat exchanger, and a bypass path unit to guide the wash water jetted from the wash water injection chamber to a side surface of the heat exchanger after bypassing an upper surface of the heat exchanger.
摘要:
The present invention relates to novel Varicella-zoster virus strain and to a chicken pox and herpes zoster virus vaccine using the same. More particularly, the present invention relates to genome DNA of VZV MAV/06 strain isolated from a Korean patient, to an open reading frame (ORF) thereof, to a protein coded by the genome DNA of VZV MAV/06 strain and the ORF thereof, and to a vaccine composition which contains the protein as an active ingredient.

Provided are a full genome DNA of a human cytomegalovirus (HCMV) strain JHC isolated from Korean patients and open reading frames (ORFs) thereof and, more particularly, UL1, UL119 and RL6.
摘要:
The present invention relates to an electrolyte for a lithium ion rechargeable battery and a lithium ion rechargeable battery including the same. The electrolyte includes a non-aqueous organic solvent, a lithium salt, and triphenyl phosphate. A lithium ion rechargeable battery including the electrolyte has improved overcharge stability and shows excellent chemical properties including reducing swelling, high-temperature storage stability, and cycle life characteristics.
