三、使用工艺简介
    手工操作型和机械操作型,手工操作型可使用时间长,固化慢,机械操作型可使用时间短,固化快。
1.手工操作工艺
а、控制环境温度在25℃,相对湿度<70%, 在低温下可能会有结晶现象,请加热复原至澄清液体后再使用。
b 、置面板于水平表面,并用不干胶固定。
c 、清洁表面沾附的灰尘与油污。
d 、正确称量Titebond015A/B按重量比1:1充分搅拌均匀。
e 、抽真空脱除混合料之气泡。
f 、慢慢倒在平板表面手工刮板均匀刮抹表面。
g 、用针挑除残留气泡。
h 、将蜂窝板放置涂胶面板之上用另一块未施胶的平板覆盖其上适当保压3小时方可第二       面操作。
12-18小时即完成固化,气温较低时,固化时间会相应廷长。
2. 机械滴注工艺

四、操作细节说明与注意事项(以手工使用为例说明):

(一)、建议操作环境:
    干燥恒温无尘车间(建议车间操作温度20℃~25℃),通风,车间湿度要控制在70%以下(65%以下更佳),室内条件固定。雨季要特别注意控制湿度。

(二)、使用准备:
(1)处理好底材(干净、干燥、没有杂质)。
(2)准备好配胶壶或他涂装工具、搅拌器等,要求:干净、干燥、没有杂质,不要使用之前配过其他胶水的配胶壶或滴胶壶、搅拌器。这点要注意
(3)正确称量,按重量比1:1称量。配完胶水后,请注意立即把胶水瓶盖子盖好、拧紧,避免空气中水气进入胶水瓶中。

(三)、搅拌均匀:按同一个方向搅拌均匀,注意搅拌时尽量到刮到底部和边壁,这样搅拌比较均匀;搅拌时间控制在90至120秒(1分半至2分钟)以内就足够了。

(四)、抽真空:
直接将搅拌好的胶水立即用真空机抽真空,时间在90至120秒(1分半至2分钟)以内。

(五)、涂胶:
手工操作胶水
建议在20分钟以内使用完配好的胶水,20分钟以内使用达到最好效果,又可以提高生产效率,超过20分钟后流动性受到影响,不利于操作。

(六)、固化:
常温25℃条件下,12-18小时左右自然固化。气温较低时,固化时间相应会廷长。若需要加温固化,建议温度为50~60 ℃,4~5小时完成固化;

五、胶水使用与存放注意事项
(一)、关于低温下结晶现象
在低于15℃以下,大于24小时放置后可能会出现结晶现象,若气温回升,结晶现象会消失。若低温下出现结晶,可将A胶在40℃至60℃温度下复原至澄清液体再使用。

(二)、关于过敏
1.手工操作可能对某些特定人群有过敏现象,例如对化学品过敏者。
2.操作时最好戴薄膜手套,操作完后应当立即用肥皂洗手及清洗与胶水有接触的部位;
3.胶水操作车间应保持适当通风,可增加鼓风机通风;真空泵所抽取的真空气体应当排到户外,不要直接排到车间环境中;
4.哮喘病人禁止使用。

(三)、关于胶水保存与使用
1.最佳的储存环境为15℃~25℃,湿度小于65%环境中。温度太高,A剂(固化剂)中的-NCO-有自聚反应,高温下会加速自聚,使其一部分聚合成三聚体,形成网状结构,影响胶体韧性。湿度大于65%环境,A剂(固化剂)中含有的-NCO-会快速和水的-OH反应,从而减少A剂中-NCO-含量,使其配比不平衡,影响消泡、表面干爽及固化后的特性(如:附着力、拉伸强度、硬度等)。
2.一般环境:一般车间环境中,密闭避光保存,可存放三个月。
3.胶水在已开封口使用情况下,应当在一个月以内用完,并注意要盖好盖子。
4.在滴胶机料桶中存放时间建议不超过三天,须在料桶排空口处安装空气干燥过滤器,有条件下最好在A/B料桶中抽完真空后,直接充入氮气来隔离空气,此目的是为了防止料桶中胶水长时间接触空气会吸收空气中的水份,产品吸潮会影响AB混合固化后品质。

(四)、关于洗板
建议用不含醇类洗板水洗板,洗板后用60℃烘1小时或80℃烘45分钟。

(五)、胶水固化
1.25℃恒温,12~18小时可自然固化。
2.温度低于15℃,且昼夜温差较大,要24至36小时固化;
3.加温固化,60℃四小时或70℃两小时;气温低时可稍微再延长加温时间;
4.冬季气温太低时,车间可增加暖风机便于缩短固化时间。

六、包装规格:
包装为25KG、50KG、200KG金属桶。

七、储运及其它注意事项:
1.此类产品为非危险品,按一般化学品运输。
2.请在15℃-25℃相对湿度<65%条件下,避光蜜闭储存,产品储存期见包装桶。
手工操作,请按配比正确称量,充分搅匀,称量大于100G,可使用时间会缩短。
3.物料眼睛接触时,立即撑开眼皮,以大量清水冲洗15分钟以上。
4.物料皮肤接触时,用布抹去后以水和肥皂冲洗患部。

2. Mechanical drip

slightly

Four, operational details and matters needing attention (manual use, for example) :

(1) and recommended operating environment:

Drying temperature dust-free workshop (recommended workshop operation temperature 20 ℃ to 25 ℃), ventilation, workshop to control the humidity below 70% (65% better), fixed indoor conditions. The rainy season to pay special attention to control the humidity.

(2), using the preparation:

(1) handle the substrate (clean, dry, no impurities).

(2) prepared with glue pot or his painting tools, mixer, etc., required: clean, dry, without impurities, do not use with other before glue glue pot or a glue pot, mixer. This note

(3) correct weighing, according to the weight ratio 1:1 weighing. Immediately after with the glue, please pay attention to the glue bottles cover and tighten, prevent moisture in the air into the bottle.

(3), stir well, according to the same direction and attention to as far as possible when mixing, scraping the bottom and side wall that mixing is uniform, Mixing time control from 90 to 90 seconds (1 1/2 to 2 minutes) is enough.

(4), vacuum:

Direct the glue will stir up immediately with vacuum machine, vacuum time from 90 to 120 seconds (1 1/2 to 2 minutes).

(5), glue:

Manual glue

Advice within 20 minutes after use with good glue, used to achieve the best effect within 20 minutes, can improve the production efficiency, liquidity is affected, after more than 20 minutes against operation.

(6), cure:

Under the condition of normal temperature 25 ℃, 12 to 18 hours natural curing. Low temperature, curing time will be at the accordingly. If need heat curing, it is recommended that the temperature is 50 ~ 60 ℃, 4 ~ 5 hours to finish curing;

Five, the glue use and storage

(a), on low temperature crystallization phenomenon

Under below 15 ℃, placed more than 24 hours after the may appear crystallization phenomenon, if the rise of temperature, crystallization phenomenon will disappear. If under the low temperature crystallization, A glue can be under 40 ℃ to 60 ℃ temperature recovery to clarify liquid to use.

(2), about allergies

1. Manual operation may be allergic to certain specific people phenomenon, such as allergic to chemicals.

2. Had better wear thin film gloves, when operation shall immediately after washing hands with soap and clean parts contact with the glue;

3. Glue workshop should maintain proper ventilation operation, can increase fan ventilation; Vacuum pump vacuum extraction by gas should be to outdoor, don't directly into the workshop environment;

4. It is prohibited to use asthma patients.

(3), about the preservation and use of glue

1. The best environment for the storage of 15 ℃ to 25 ℃, humidity is less than 65% in the environment. Temperature is too high, A agent (agent) in the - NCO - have since reaction, high temperature will accelerate the poly, make part of aggregate into trimer, form A mesh structure, affect colloid toughness. Humidity higher than 65%, A agent (agent) contained in the - NCO - quickly and water - OH reaction, thus reducing A - NCO content in the agent, the ratio imbalance, influence the characteristics of foam, the surface is dry and after curing (such as adhesion, the tensile strength, hardness, etc.).

2. The general environment: general workshop environment, sealed, avoid light preservation can be stored for three months.

3. Glue in kaifeng mouth already use cases, shall be finished within a month, and pay attention to cover the lid.

4. In the glue material barrel storage time suggest no more than three days, must be installed in VAT emptying mouth dry air filter, under the condition of the best in A/B after finished the vacuum tank, filling the nitrogen to isolate air directly, the purpose is to prevent material barrels glue contact air will absorb moisture in the air for A long time, the product absorption of moisture will affect quality AB mixed after curing.

(4), about the washing plate

Suggest using do not contain alcohol washing plate washing plate, wash the plate with 60 ℃ bake for 1 hour or after 80 ℃ bake for 45 minutes.

(5), glue curing

1.25 ℃ temperature, natural curing 12 to 18 hours.

2. The temperature below 15 ℃, and the larger temperature difference between day and night, 24 to 36 hours curing;

3. Heat curing, 60 ℃ four or 70 ℃, for two hours; Low temperature can be a little bit longer heating time.

4. When the temperature is too low in winter, workshop heater is easy to shorten the cure time will increase.

Six, packaging specifications:

Packing: 25 kg, 50 kg, 200 kg metal barrels.

Seven, storage and transportation, and other matters needing attention:

1. This kind of product is a non-dangerous goods, according to the general chemical transportation.

2. Please at 15 ℃ to 25 ℃ relative humidity < 65% conditions, avoid light honey store closed, the shelf life of product packaging barrels.

Manual, please according to the proportion of correct weighing, fully stir, weighing more than 100 g, can use time will be shorten.

3. Material eye contact, immediately open eyes, rinse with water for 15 minutes.

4. Skin contact materials, cloth to wipe with soap and water after washing department.

* note: the above performance data for the products in 70% humidity, temperature 25 ℃ when the typical data of test, for customers to use as a reference only, cannot fully guarantee in a particular environment can be achieved when all the data. Please customers to use, will be subject to the measured data.
