Бельзона 1321 инструкция по применению

Belzona 1321 (Ceramic S-Metal)

Двухкомпонентное эпоксидное покрытие с керамическим наполнителем, обеспечивающее долговременную защиту металлов от эрозии и коррозии. Это эпоксидное покрытие, не содержащее растворителя, обладает отличной химической стойкостью и адгезией к большинству жестких подложек. Высокая прочность на сжатие позволяет использовать Belzona 1321 (Ceramic S-Metal) в том числе в качестве инъекционного материала для создания прокладок.

Этот материал холодного отверждения исключает потребность в горячей обработке, а также  легко смешивается и наносится без применения специального оборудования.

Основные преимущества:

• Долговременная защита от эрозии и коррозии
• Отличная адгезия к различным жестким поверхностям, включая сталь, алюминий, медь, латунь и армированный стеклопластик
• Высокая прочность на сжатие
• Отличная химическая защита против широкого спектра химических веществ
• Отсутствие растворителя снижает риск причинения вреда здоровью и пожароопасность
• Отсутствие усадки, объемного расширения и деформации

Belzona 1321

FN10025 (CERAMIC S-METAL)

INSTRUCTIONS FOR USE

www.belzona.com Publication No. 01-04-13

1. TO ENSURE AN EFFECTIVE MOLECULAR WELD

i) METALLIC SURFACES — APPLY ONLY TO BLAST

CLEANED SURFACES

a) Brush away loose contamination and degrease with a rag soaked in Belzona

® 9111 (Cleaner/Degreaser) or any other

effective cleaner which does not leave a residue e.g. methyl ethyl ketone (MEK).

b) Select an abrasive to give the necessary standard of

cleanliness and a minimum depth of profile of 3 mils (75 microns).

Use only an angular abrasive. c) Blast clean the metal surface to achieve the following

standard of cleanliness:

ISO 8501-1 Sa 2½ very thorough blast cleaning American Standard near white finish SSPC SP 10 Swedish Standard Sa 2½ SIS 05 5900

d) After blasting, metal surfaces should be coated before any

oxidation of the surface takes place. SALT CONTAMINATED SURFACES

Metal surfaces that have been immersed for any periods in salt solutions e.g. sea water, should be blasted to the required standard, left 24 hours to allow any ingrained salts to sweat to the surface and then washed prior to a further brush blast to remove these. This process may need to be repeated to ensure complete removal of salts. The soluble salt contamination of the prepared substrate, immediately prior to application, should be less than 30mgs/m². ii) SURFACES ALREADY REBUILT WITH BELZONA

® 1311

(CERAMIC R-METAL)

a) If overcoating takes place within 2 hours, no further surface

preparation is required. b) After this maximum overcoating time has elapsed roughen

the Belzona® 1311 preferably by brush blasting before

applying Belzona® 1321.

2. COMBINING THE REACTIVE COMPONENTS

Transfer the entire contents of the Solidifier can into the Base module. Mix thoroughly together to achieve a uniform material free of any streakiness. 1. MIXING AT LOW TEMPERATURES

To ease mixing when the material temperature is below 41°F (5°C), warm the Base and Solidifier modules until the contents attain a temperature of 68-77°F (20-25°C). 2. WORKING LIFE From the commencement of mixing, Belzona

® 1321 must be

used within the times shown below. Temperature 41°F

(5°C) 59°F (15°C)

77°F (25°C)

86°F (30°C)

Use all material within 2 hours 1 hour 30 min. 20 min.

3. MIXING SMALL QUANTITIES For mixing small quantities of Belzona

® 1321 use:

4 parts Base to 1 part Solidifier by volume 11 parts Base to 1 part Solidifier by weight 4. VOLUME CAPACITY OF MIXED BELZONA

® 1321

25.7 cu.in. (425 cm³) per kg.

3. APPLYING BELZONA® 1321

FOR BEST RESULTS Do not apply when:

i) The temperature is below 41°F (5°C) or the relative humidity is above 90%.

ii) Rain, snow, fog or mist is present. iii) There is moisture on the metal surface or is likely to be

deposited by subsequent condensation. iv) The working environment is likely to be contaminated by

oil/grease from adjacent equipment or smoke from kerosene heaters or tobacco smoking.

a) Apply the Belzona

® 1321 directly on to the prepared

surface with a stiff bristled brush or with the plastic applicator provided.

To achieve the correct film thickness of 10 — 15 mils

(250 — 375 microns), a practical coverage rate of 11 sq. ft (1 m²) per kg unit should be obtained.

HEALTH & SAFETY INFORMATION Please read and make sure you understand the relevant Material Safety Data Sheets.

b) As soon as possible after application of the first coat, apply a further coat of Belzona

® 1321 as in (a) above. This time

will be 1 — 2 hours at 68°F (20°C). The first coat must not be left longer than 6 hours before overcoating, irrespective of temperature. Should this occur, then the surface should be brush blasted or abraded before commencing application.

COLOR

Belzona® 1321 is available in blue and gray to facilitate application and to prevent misses. These colors are for identification only and there will be some variation between batches. In service the color of the applied product may change.

CLEANING

Mixing tools should be cleaned immediately after use with Belzona

® 9111 or any other effective solvent e.g. Methyl ethyl

ketone (MEK). Brushes, injection guns, spray equipment and any other application tools should be cleaned using a suitable solvent such as Belzona

® 9121, MEK, acetone or cellulose

thinners.

4. COMPLETION OF THE MOLECULAR REACTION

Allow Belzona

® 1321 to solidify as below subjecting it to the

conditions indicated. Temper-ature

Movement or use involving no loading

Machining and/or light loading

Full mechanical/ thermal loading or water immersion

Chemical contact

41°F/ 5°C 12 hours 18 hours 7 days 10 days

50°F/10°C 8 hours 12 hours 3 days 5 days

59°F/15°C 5½ hours 9 hours 2 days 3 days

68°F/20°C 4 hours 6 hours 1½ days 2 days

77°F/25°C 3½ hours 4½ hours 24 hours 1½ days

86°F/30°C 2 hours 3 hours 18 hours 1 day

5. MACHINING Belzona

® 1321 is extremely difficult to machine down by turning,

using conventional or carbide tipped tools. However, it can be machined using diamond tipped tool. Alternatively it can be machined by grinding, but this should be carried out as soon as possible after the solidified times shown.

6. FINAL SOLIDIFICATION OF BELZONA® 1321

When time is important and equipment usage is pressing, then by installing forced air heaters and taking steps to contain this heat around the equipment being reclaimed, final solidification time can be as little as 24 hours. Due allowance must be made for «warming up». A final physical check can be made as precaution by taking a metal object and tapping the surface of the Belzona

® 1321. Any

partially solidified or soft spots will give a dull tone in relation to the metallic tone offered by solidified Belzona

® 1321.

If there is any doubt regarding final solidification then BE SAFE — MAKE MORE TIME.
