Description
Technical field
The present invention relates to a kind of cable making method, in particular to a kind of deionized water insulated cable system and
Manufacturing method.
Background technique
Cable we it is normally understood be by several or several groups of wire strandings form, mutually insulated between every group of conducting wire, often
Group insulated conductor is twisted cable core entirety, and whole outside is coated with coat of metal and non metallic sheath layer again.Cable can
To set up in the sky or be mounted in underground, the bottom, it to be used for telecommunication or power Transmission.
Plastics, rubber etc. are generallyd use between the conducting wire of cable as dielectric, are also had using insulating oil or gas work
For dielectric.
Water is spoken of, first it is envisioned that the substance that we be unable to do without daily, without water, we are just without life.It talks
To using water as dielectric, we are it is envisioned that water is the good conductor of electricity first, since water is the good conductor of electricity, and how
Water may be used to be used for the insulation of power transmission as dielectric? use water as dielectric to explain, we are first from water
Concept and composition dissected.
Water (H2O) the inorganic matter being made of two kinds of hydrogen, oxygen elements, is at normal temperatures and pressures the transparent liquid of colorless and odorless
Body.Water is one of most common substance, is that the valuable source of all life existence and organism are most heavy including humans
The component part wanted.Water plays an important role in Life Evolution.The mankind begin to produce water understanding very early, east
Water is all considered as a kind of basic component in the view of matter of Ancient Western simplicity, water is one of ancient Chinese five-element；West
Also there is water in the four-element theory in ancient times.
The pure substance of water is colourless, tasteless, transparent liquid, boiling point: 100 DEG C of (height above sea level 0m, gas at normal temperatures and pressures
When pressure is a standard atmospheric pressure), freezing point: 0 DEG C, three phase point: 0.01 DEG C, specific heat capacity: 4.186kJ/kg DEG C of (0.1MPa
15 DEG C), density: 1.0 × 103kg/m3(at 4 DEG C) critical-temperature: 374.2 DEG C, belong to polar molecule.
Chemical formula: H2O, structural formula: H-O-H (104.5 ° of angle between two hydrogen-oxygen keys), relative molecular mass: 18.016.
The stability of water shows that 2000 DEG C or more just start to decompose.The oxidisability of water: when water is with compared with active metal or carbon reaction, table
Existing oxidisability, hydrogen are reduced into hydrogen 2Na+2H2O=2NaOH+H2, Mg+2H2O=Mg (OH)2+H2.The electrolysis of water, water is straight
Under galvanic electricity effect, decomposes and generate hydrogen and oxygen.Hydration reaction, water can basic anhydride, most of acid with active metal
Property oxide and certain unsaturated hydrocarbons occur hydration reaction, Na2O+H2O=2NaOH, CaO+H2O=Ca (OH)2.The electricity of water
From in water almost without hydrone ionization generation ion.Water is amphiprotic substance, existing hydrogen ion (H+), also have hydroxyl from
Son (OH-), but pure distilled water is neutral.
For daily life, moisture are as follows: 1, underground water and surface water；2, hard water and soft water；3, raw water and water purification；4,
Pure water and distilled water；5, pure water and ultrapure water；6, purified water and water for injection.
Here talk again pure water and ultrapure water, pure water be with reverse osmosis, distillation, the preparation of the methods of ion exchange
Deionized water, TDS value usually<5PPm, conductivity usually<10 μ s/cm (resistance value>0.1M Ω cm)；Ultrapure water be with from
Pure water is further purified deionization to obtain the final product by the methods of son exchange, distillation, electric desalination, and TDS value can not be surveyed, conductivity usually <
0.1 μ s/cm (resistance value > 10M Ω cm), ion almost removes.Theoretically most pure water resistance value is 18.25M Ω
cm。
Deionized water (deionized water) refers to the pure water eliminated in after ionic species impurity.International standardization
It organizes as defined in ISO/TC47 " deionization " is defined as: " deionized water is complete or incompletely removes ionic species, refers mainly to
Using ion exchange resin treatment method.", the method that present technique mainly uses RO reverse osmosis is produced.In semicon industry
In, deionized water is referred to as " ultrapure water " or " high purity water ".
Usual deionized water can be divided into 4 classes:
A class: it only requires and water intermediate ion is removed into major part, so that water is purified, conductivity is normally controlled in 200~10 μ
s/cm；
B class: deionized water conductivity is controlled in 10~1 μ s/cm, food rank is belonged to；
C class: deionized water conductivity is controlled in 0.9~0.1 μ s/cm, belongs to fine industrial rank；
D class: by the control of deionized water conductivity more than 0.07 μ s/cm, belong to electronics rank.
It is traditional water process mode that ion exchange resin, which produces deionized water:
Its typical process flow are as follows: raw water → more medium filter → active carbon filter → accurate filter cation bed →
Anion bed → mixed bed → postposition cartridge filter → uses water spot.Feature: pollution is bigger, and the degree of automation is low, and initial stage investment is low.
Reverse osmosis water treating equipment combines the processing mode for producing deionized water with ion-exchange unit:
Its typical process flow are as follows: raw water → more medium filter → active carbon filter → accurate filter is reverse osmosis
Equipment → mixed bed → ultrapure water tank → ultrapure water pump → postposition cartridge filter → uses water spot.Feature: pollution is small, automates journey
Degree is high, and initial stage investment is medium, moderate.
Reverse osmosis water treating equipment combines the processing mode for producing deionized water with electrodeionization (EDI) equipment, this is one
Kind produces the most up-to-date techniques and a kind of environmental protection, economy and the huge ultrapure water preparation process of development potentiality of ultrapure water.
