Brief introduction

The sea water is to imply much clock salt electrolyte aqua, moreover still imply to fuse oxygen, marine life, its electric resistance leads very small, past decay speed than in the soil quickly get much.Get soil in some anoxia in, also produce from be disgusted with an oxygen germ to arouse germ corrosion.Moreover still having to produce physics from metal surface deliquescence is causable of physics decay.

Have no water rich the H2 S methyl alcohol and water content are very low of rich the H2 S methyl alcohol has the hydrogen opens to split(HISCC) in response to the dint corrosion or such as total know to all of is opened the danger of crack in response to the dint corrosion by the sulphide with water acidity air formation.With contain aqueous of rich the H2 S methyl alcohol fluid is contrary, decay a hit in the methyl alcohol in operation special fluid isn't the function of PH or HCN density.

If attain to the following standard of , in the standard item of have no the operation condition of water or low water content rich H2 S methyl alcohol is viable:

- Operate temperature TO ≤ 110 ° Cs

- The methyl alcohol contains the amount of water W ≤ 3%

- H2 S partial pressure PH2 S>0.0035 bars

The antisepsis of metal surface first is in addition to rust, in addition to the rust promises the key and foundation of antisepsis quality.Such as the rust quality could not reach a norm request, besides which, , after painting the rust spot then soon will suddenly and violently leak out and lost the function of antisepsis thus, so in addition to the rust is the point of check.

Standard:The steel material surface has no it is thus clear that of grease and dirty mark, and didn't adhere to ricketily oxidize attachments such as sheet iron, rust and paint Tu Ceng etc., bottom material's rearing part of surfaces shoulded have metal sheen.

In metal surface in addition to the rust after attaining the Class request can start Tu Qi , according to first bottom paint, in the center paint, noodles paint of the sequence carry on.

1, the antisepsis paint anticipate the choice in noodles paint color in the middle of designing to start construction diagram, the designs all stipulated a bottom paint, in the center paint, noodles paint

Of number, the name of the paint and the thickness of the paint film

2, paint the check of film thickness

Strictly carry out the Tu Qi 's number and thickness that the diagram paper requests, for paint the thickness of film generally

The adoption measures a thick instrument to carry on measuring direct and promises paint film thickness from the on the side.

3, Tu Qi start construction to request

(1)Tu Qi starts construction environment condition.Environment temperature 5~38 ℃ ;Relative humidity:The ≤ in the factory premises is 80%, open-air ≤ 85%;The steel plate surface temperature is higher than a dewdrop above 3 ℃ .

(2)Paints ex- surface to prepare a processing request.Need paints of the havings reach a piece to carry on surface to prepare a processing and include to clean a greasy dirt and sharp angle dozen and whet, the clearance Han lump, Han residue and surface clean up and get have no oil, have no water, have no the clean surface of filth.

(3)Spray sand to use to whet to anticipate a request.The steel sand has to sweep, dry, have no greasy dirt, have no

Dissolubility salt etc., if affect by damp and cold, should replace new sand or aridity to attain to request an empress again

Use.Again and again the steel sand use will have to fall in pieces, creation dust, therefore want Shai usually

The cent removes a dust, miscellaneous articles or objects.

(4)The coating requests.The coating checks sign, name, model number, batch number after entering the field,

Produce date and pack weight(capacity), and amount...etc..Store in warehouse to deposit after checking without any error.Press the batch number random a sampling to send check.Examine the item as solid content and glue degree, dry index signs, such as time, pliant and tough and adhesive strength...etc..

(5)Other requests.Spraying a qualified work piece of sand should at Tu Qi inside the 4 hs, each paint brushes of of the shortest and most long-term partition should with varnish the manual agree with.Exceed the most long-term partition of should press to request to carry on a processing to Tu Ceng's surface.Tu Ceng at physically dry before can not be drenched.At the same time be apart from Han to sew to to reserve a 50~100 mm breadth temporary not Tu Qi , press Tu Qi to request the layering Tu Qi after welding completion.
