Abstract
The invention discloses a water-finding paste capable of changing color when wet, belonging to the technical field of the preparation of fine chemical products. The water-finding paste provided by the invention consists of the following substances in parts by weight: 30-40 parts of polyethylene glycol 600, 20-30 parts of polyethylene glycol 200, 1-10 parts of phenothalin, 5-15 parts of calcium oxide, 10-30 parts of plaster, 0.5-10 parts of gas white carbon black and 0.5-5 parts of glycerol. The water-finding paste provided by the invention is prepared by mixing and evenly stirring the above substances at a normal temperature. The water-finding paste has the advantages of capability of rapidly changing color when wet, clear color limit and small possibility of falling off.
Description
Technical field
The invention belongs to fine chemical product preparing technical field, be specifically related to a kind of water-finding paste of meeting water variable color.
Background technology
Water-finding paste is a kind of pasty masses, in the time running into water, can demonstrate immediately different colors.Water-finding paste is widely used in measuring in the storage facilities such as oil tank, bunker and measuring wherein water layer thickness in the industries such as oil, chemical industry, shipping together with dip stick, is also applicable in addition the measurement of all petroleum productss, sulfuric acid, hydrochloric acid, nitric acid, ammoniacal liquor, liquid soap, salt and chloride water cut.Existing water-finding paste product is owing in use there being the lotion variable color time slow (become aubergine by white after chance water and need 10～20 seconds), after the easy imbibition of the unintelligible and water-immersed lotion part in variable color boundary line, be the problems such as powdery fast-falling and cause practical operation test inconvenience relatively, therefore market share is not high.Chinese patent CN92103400.8 openly expects a kind of water checking paste composition for detection of water layer height in oil or oil package, in this invention, use triethanolamine to make the variable color of developer phenolphthalein as alkaline matter, although use epoxy resin to preferably resolve slow problem of variable color time as liquid phase carrier, but because wherein the contained triethanolamine ratio that very easily absorbs water is higher, in the time that soak time in water is slightly long, easily in water, dissolves and cause lotion to come off, make to observe variable color boundary line.
Summary of the invention
The object of the invention is for above-mentioned the deficiencies in the prior art, a kind of water-finding paste of the chance water variable color taking phenolphthalein as developer is provided.
Composition and the parts by weight thereof of a kind of water-finding paste of meeting water variable color provided by the present invention are as follows:
Macrogol 600: 30～40,
Macrogol 2000: 20～30,
Phenolphthalein: 1～10,
Calcium oxide: 5～15,
Gypsum: 10～30,
Gas-phase silica: 0.5～10,
Glycerine: 0.5～5.
Water-finding paste provided by the present invention liquid phase carrier used is the potpourri of Macrogol 600 and Macrogol 2000.By liquid phase carrier by each component of water-finding paste in conjunction with as a whole paste, so that smear and clean.Suitable liquid phase carrier should modest viscosity, has lower oil-soluble and water-soluble, and the lotion homogeneity making is like this good, simultaneously all not soluble in coil neutralization water, can have the long period.
Water-finding paste provided by the present invention developer used is white phenolphthalein powder.In aqueous solution, when phenolphthalein runs into hydroxide ion (OH
-) time can become aubergine by white, thereby can indicate water layer position.
What water-finding paste provided by the present invention was used makes lotion meet water generates OH
-material be that granularity is less than 50 object lime powders.Lime powder in lotion can generate calcium hydroxide after meeting water, discharges finite concentration OH
-.
What water-finding paste provided by the present invention used can the make lotion rapidly material of water suction is less than 50 object gypsum powders for granularity.The existence of debita spissitudo gypsum can ensure can absorb water rapidly and ensure that calcium oxide can fully react after lotion contacts with water, effectively shortens the water-finding paste variable color time.
What water-finding paste provided by the present invention used can make variable color boundary line keep stable material is gas-phase silica.Suitable gas-phase silica can regulate the lypohydrophilic character of lotion, thereby ensures that the color boundary line forming after water-finding paste variable color drift does not occur and causes measuring inaccurate.
In water-finding paste provided by the present invention, also add appropriate glycerine for improving lubricated, the resistance to frost of lotion.
A kind of water-finding paste of meeting water variable color provided by the present invention is by making after mixing and stirring above-mentioned composition at normal temperatures and pressures.This water-finding paste have advantages of meet after water variable color rapidly, clear, the difficult drop-off in color boundary line.
