Clean room Clean Class Level Definition

Clean room clean class level definition: clean room clean class level of their main point unidirectional flow, non- unidirectional flow two ways.

Unidirectional flow (1-100 class):

1- 100 class clean room, organizations are using the one-way flow of air supply, clean indoor air that same section at any point, airflow direction and speed are consistent, This allows clean room air like “piston ", as indoor dust particles fastest away. To achieve the “piston " effect, HEPA filter needs full covered of room ceiling can be achieved only charge a one-way direction of airflow.

Non- unidirectional airflow (1000-100.000 class) clean room:

1000- 100.000 class airflow direction is different with above 100class clean room, indoor air is uneven parallel flow velocity was not accompanied by reflow or vortex , which mainly depends on the continuous flow of clean indoor air dilution , will gradually discharge DC high voltage generator indoor pollution , to achieve purification . achieve different purification level, mainly by the amount of air per unit time to the performance of the different.

Optical Products Clean room--LED Industrial Cleanroom Project

Optical Products clean room generally applicable to electronic instrumentation, computer, semiconductor plants, automotive, aerospace industry, lithography, micro machine manufacturing and other industries , in addition to air clean class level, but also to guarantee the achievement in addition to static requirements. The following represent the most modern LED industry as an example, photoelectric optical industry clean purification plant

LED purification plant engineering installation and construction Case Study: In this design, there is the end of some of the purification process of installing clean room, its purification cleanliness is generally one thousand or ten thousand or a hundred thousand grade purification clean room installation.

Backlit screen class cleanroom installation of these products are mainly press shop, assembly purification clean room, its cleanliness is generally ten thousand or one hundred thousand purification clean room.

LED indoor air clean room installation parameters required :
    1 ) Temperature and humidity requirements: temperature is generally 24 +2 ℃, relative humidity of 55 +5%.
    2)  Large fresh air. As these purification clean room most are personnel, you can take the following should be the maximum value according to the following values: non- unidirectional flow clean room workshop purify total air volume 10-30 %; compensation indoor ventilation and keep the interior positive the amount of fresh air required pressure value; ensure indoor fresh air per person per hour of ≥ 40m3 / h.

   3)  Air volume supply. In order to meet the clean class level, the heat and humidity balance within the clean purification plant, require a larger air volume, on 300 square meters of workshops , ceiling height of 2.5 meters , if it is thousand grade purification clean room, air volume on need 300 × 2.5 × 30 = 22500m3 / h of air volume ( ACH is ≥ 25 times / h); If you are one hundred thousand purification clean room, air volume you need 300 × 2.5 × 20 = 15000m3 / h of air volume ( ventilation frequency is ≥ 15 times / h).

The Automatic Flat foam seamless sealing injection machine for Our HEPA filter

The Automatic Flat foam seamless sealing injection machine

随着制造业的发展和人们对产品质量要求的不断提高，传统的密封圈、密封垫已经或正在被密封胶替代。安莱最新引进的全自动平面发泡无缝密封注胶机与传统手工注胶相比，具有以下特点：

With the development of the manufacturing and the continuous improvement of the product quality requirements , the traditional gasket、sealing plate have been or are being replaced by sealant. Anlai latest introduction of automatic flat foam seamless sealing  injection machine compared with the traditional manual dispensing with the following features :

1.       卓越的密封性 Excellent sealing

传统的手工贴密封条不能做到100％的无缝密封效果；而平面发泡能做到完全无缝密封，发泡密封条具有柔软性极佳、弹性好、永不变形、不易脱落、环保、外形美观等特性。

The traditional manual affixed seal can not achieve 100% seamless sealing effect; but the flat foam can be completely seamless seal, foam sealing strip having superior softness, good elasticity, never deformation, not falling, environmental protection, beautiful appearance and other characteristics.

2.       精确的定位 Accurate positioning

传统手工贴的密封条位置难以确保，且直线度不好，外型不美观；而发泡机使用专用计算机控制和多轴联动数控系统控制，能高效、精确的保证发泡位置的统一性，发泡后的气密性极好。

The traditional manual seal affixed position is difficult to ensure, and the linearity is not good, appearance is not beautiful; but the foaming machine dedicated computer control and multi axis NC control system, can be efficient, accurate assurance the foaming position unity, after foaming tightness is excellent.
