Introduce of Hydrocarbon Solvent
instruction of Hydrocarbon:
Hydrocarbon Series Rinse , a new product with excellent chemical comparability and compatibility that can wash away the greasy and accretion particulate on the surface of articles. Because it's only formed by carbon and hydrogen there for has no such problems which trichlorethylene , water-soluble degrease agent and other solvent may cause . In this new modern industry that high efficiency , low cost and environmentalism are required , Hydrocarbon Series Rinse is really a good product.

Species
Item
Hydrocarbon Series Rinse
Trichlorethylene,
Dichloromethane,
Methoklone
Industrially Petrol
Water-soluble degrease agent
Constituent
carbon and hydrogen , for example:
N-PARAFFIN ISO-PARAFFIN
NAPHTHENES
The structures are:
CL CL  
CL-C
=C
-H
which contains small amount of water and antacid (usually ammoniun stearate)
carbon, hydrogen and huge amount of S.P , aromatic and metallic ions.
Surfactants and additions (cleaning efficiency : alkalinity is better then neutral)
Toxicity
Extremely low ( 0.1% of trichlorethylene)
Extremely highWill be tabooed in the future
(no allow in Taiwan already)carcinogen

Influence to metal surface
None
not participate in the reaction on metal surface
If not well-controled ,
will corrode the surface and cause etching
Constituents not stable and often remain on surface
(sometimes can't observed with naked eye)
Yes
May produce some unwanted compound like hydroxide
Acidify
None
Hydrocarbon is a neutral solvent that will not participate during the reaction . there for no acidification
Yes
Reaction as below:In order to make trichlorethylene creat continually cracks , lots of heat were added during the process which came along with acid-forming like hydrochloric. After a while , this will cause etching and damage your facilities.
Constituents not stable there for can not estimate.
Could have , but not sure
None
But after rinsing , surfactants and acidify surface may cause polarization . Antirust measure must be taken to prevent oxidization
Reclamation
Recyclable By vacuum decompress dissociation
Recyclable By distilled But the process will cause acidification
will Cause pollution
will Cause pollution
PH
Neutral
Easy to becomes acidic
Should be neutral
Alkalinity or neutral
Waste water handling
Recycled by recycle-system
Could be recycled But not able to dispose the waste water .
The production cost will be too high if handled by coercion.
Need to contact with the waste water handling agent
Can't drain the waste water without disposition
Antirust
Because impermanency nonpolarity occurs after the surface been washed , this can help antirust
None
Could have but not sure
None
Need antirust measure after washed (easy to be oxidized)

Consumption
After running the cleaning process we discovered that whthin a recycle system in it , the consumption of rinse is about 1/3-1/5 of trichlorethylene
Average
Huge
Need huge amount of water and at the same time produced lots of waste water which needs many efforts to handle.
There will be a concern of pollution.
Remark
 
By the ascriction of "Montreal Protocol on Substances that Depletethe Ozone Layer", trichlorethylene will be prohibited in the world.
 
 
Consequence:
The orientation for Hydrocarbon Series Rinse is coming in the near future because it's low toxicity , high cleaning efficiency and environmentalistic characteristic. All these advantages are not provided by trichlorethylene and other rinse. We hope the informations we provide can do you some helps.
