The present invention relates to a kind of qualitative judgement method of pitch coloring degree in fertilizer coating agent, carry out according to the following steps：Take appropriate pitch heating and melting, accurately 1 part of bitumen samples is weighed to be placed in aluminium alloy cup, weigh and be placed in pitch weight identical machine oil in same aluminium alloy cup again, heat while stirring to 70-90 DEG C, after sample to be mixed dissolves each other completely, 0.1 0.5g composite samples accurately are weighed in glass beaker, then weigh 30 70g fertilizer in another glass beaker, and both carry out mixing parcel；Then HunterLab colour photometer determination sample Lab values are used.The method of the present invention can be applicable the qualitative judgement of pitch coloring degree in fertilizer coating agent, can effectively prevent pitch color change difference in use, simple to operate, rapid, it is as a result more stable the features such as.
Description
Technical field
The present invention relates to field of fertilizer manufacturing.
Background technology
With the progress of fertilizer production technology, fertilizer production producer is directed to the requirement more and more higher of fertilizer appearance color, fertilizer
The species of material appearance color is also progressively increasing.Wrapped up compared to traditional pigment, pitch particularly plant asphalt have cost it is low,
Pollute the effects such as small, heat-resisting, moisture-proof, sustained release fertilizer efficiency.Enter face occurs using process in fertilizer in order to effectively prevent pitch
Color change, this just needs a kind of qualitative judgement method of pitch coloring degree in fertilizer coating agent.
The content of the invention
The purpose of the present invention judges pitch coloring degree in fertilizer coating agent in order to fast qualitative, is used so as to reduce
The risk of color change difference in journey, and a kind of qualitative judgement method of pitch coloring degree in fertilizer coating agent is provided.This hair
The method of bright offer goes for the analysis of pitch coloring degree in various fertilizer coating agents.
The present invention is realized by following technology：
The qualitative judgement method of pitch coloring degree, is carried out according to the following steps in a kind of fertilizer coating agent：Take appropriate pitch
Heating and melting, accurately weigh 1 part of bitumen samples and be placed in aluminium alloy cup, then weigh be placed in pitch weight identical machine oil it is same
In aluminium alloy cup, heat while stirring to 70-90 DEG C, after sample to be mixed dissolves each other completely, accurately weigh 0.1-0.5g mixing examinations
Sample is in glass beaker, then weighs 30-70g fertilizer in another glass beaker, and both carry out mixing parcel；Then use
HunterLab colour photometer determination sample Lab values.
Described pitch is commercial pitch or plant asphalt
The measure operation of HunterLab colour photometers is operated by operational manual.
The method of the present invention can be applicable the qualitative judgement of pitch coloring degree in fertilizer coating agent, can effectively prevent to drip
Blue or green color change difference in use, it is simple to operate, rapid, it is as a result more stable the features such as.Method provided by the invention can
With the analysis of the pitch coloring degree suitable for various fertilizer coating agents.
