Wide Industry Applications Of Clean Workshops

Cleanrooms Play An Indispensable Role In Many Industries Due To Their Strict Control Over The Environment, Becoming A Key Infrastructure For Ensuring Product Quality And Production Safety.

Semiconductor Industry: The "clean Fortress" Of High-end Manufacturing

Semiconductor Manufacturing Can Be Regarded As One Of The Fields With The Most Stringent Requirements For Cleanliness. From Wafer Manufacturing, Photolithography, Etching To Chip Packaging, Every Step Does Not Allow Interference From Tiny Particles, As Even Nanoscale Dust Particles Can Cause Chip Short Circuits, Performance Degradation, Or Even Scrap. Therefore, The Semiconductor Industry Often Adopts ISO Class 1-5 Cleanrooms. In The Advanced Process Chip Manufacturing Of 7 Nanometers And Below, The Cleanroom Not Only Strictly Controls The Number Of Dust Particles, But Also Achieves Extreme Precision In Temperature And Humidity Control. Temperature Fluctuations Need To Be Controlled Within ± 0.1 ℃, And Relative Humidity Needs To Be Controlled Within 40% -60% To Ensure The Accuracy Of Key Processes Such As Photolithography And Ensure High Yield Of Chips. For Example, Global Leading Chip Manufacturers Such As TSMC And Samsung Have Advanced Process Chip Production Workshops Equipped With Top-notch Clean Technology And Equipment, Providing Core Chip Support For The Global Electronics Industry.

Biomedical Industry: A "sterile Space" That Safeguards Life And Health

In Fields Such As Drug Production, Medical Device Manufacturing, And Biological Research, Clean Workshops Are An Important Guarantee For Ensuring Product Safety And Effectiveness. The Production Of Sterile Drugs, Such As Injections And Powder Injections, Must Be Carried Out In A Class 100 Or Class 1000 Clean Environment To Prevent Microbial Contamination. In The Vaccine Production Process, Every Step From Cell Culture, Virus Inoculation, Purification To Vaccine Filling Must Be Completed In A Strictly Clean Environment To Avoid External Factors Affecting The Activity And Quality Of The Vaccine. Taking The Production Of COVID-19 Vaccine As An Example, In Order To Meet The Global Demand For Mass Vaccination, Many Pharmaceutical Enterprises Have Built Or Renovated High Standard Clean Workshops. These Workshops Not Only Have A High Level Of Cleanliness, But Also Are Equipped With Strict Biosafety Protection Measures To Ensure The Safety And Effectiveness Of The Vaccine Production Process. In Addition, In Terms Of Medical Device Manufacturing, The Production Of Implantable Medical Devices Such As Heart Stents And Artificial Joints Also Needs To Be Carried Out In Clean Workshops To Prevent Bacteria, Viruses, And Other Microorganisms From Adhering To The Surface Of The Devices And Causing Postoperative Infections.

Food Industry: The "clean Defense Line" To Ensure Food Safety

Food Processing Also Has High Requirements For Cleanliness, Especially For High Value-added Foods Such As Baked Goods, Meat Products, Dairy Products, Etc. A 100000 Level Clean Workshop Is Commonly Used In The Processing And Packaging Of Food, Which Can Effectively Control Pollution Sources Such As Dust, Microorganisms, And Insects. In The Production Of Baked Goods, A Clean Workshop Can Prevent Flour And Other Raw Materials From Being Contaminated By External Factors During The Processing, Ensuring The Taste And Quality Of The Food; In The Meat Processing Workshop, A Strict Clean Environment Helps To Suppress Bacterial Growth And Extend The Shelf Life Of Meat Products; The Production Of Dairy Products Has Stricter Control Over Microorganisms, And Clean Workshops Can Ensure That Raw Materials Such As Milk Are Not Contaminated During Processing, Storage, And Packaging, Safeguarding Consumer Health. For Example, Large Dairy Companies Such As Mengniu And Yili Use High Standard Clean Technology In Their Production Workshops, Ensuring That The Entire Process From Milk Source Reception, Sterilization, Filling To Packaging Is Carried Out In A Clean Environment To Ensure Product Quality, Safety, And Reliability.

New Energy Industry: "Clean Power" For Green Development

With The Booming Development Of New Energy Industries Such As Photovoltaics And Lithium Batteries, The Application Of Clean Workshops Is Becoming Increasingly Widespread. In The Production Of Photovoltaic Cells, In Order To Ensure The Photoelectric Conversion Efficiency Of The Cells, It Is Necessary To Produce Them In A Clean Environment To Prevent Impurities From Affecting The Performance Of The Cells. For Example, In Processes Such As Polycrystalline Silicon Ingot Casting, Silicon Wafer Cutting, And Battery Cell Manufacturing, The Presence Of Dust Particles And Metal Impurities Can Reduce The Conversion Efficiency Of The Battery Cells. Therefore, Workshops With A Cleanliness Level Of 10000 Or Higher Are Usually Used. In The Production Process Of Lithium Batteries, The Control Of Moisture And Dust Is Very Strict, Because Even Trace Amounts Of Moisture May React Chemically With The Internal Materials Of The Battery, Affecting The Safety And Service Life Of The Battery. Therefore, Lithium Battery Production Workshops Generally Require Cleanliness Levels Of Thousands Or Even Hundreds, While Strictly Controlling The Humidity Inside The Workshop To Ensure That The Production Environment Meets The Requirements. Leading Lithium Battery Companies Such As CATL And BYD Have Built Large-scale High Standard Clean Workshops To Meet The Growing Market Demand And Promote The Development Of The New Energy Vehicle Industry.

Other Industry Applications

In Addition To The Aforementioned Industries, Cleanrooms Also Have Important Applications In Aerospace, Optical Instruments, Precision Machinery Manufacturing, And Other Fields.

. In The Aerospace Field, The Manufacturing And Assembly Of Aircraft Engine Components, Aviation Electronic Equipment, Etc. Need To Be Carried Out In A Clean Environment To Ensure The Reliability And Safety Of Products; The Manufacturing Of Optical Instruments, Such As Camera Lenses, Microscope Lenses, Etc., Requires Extremely High Cleanliness. Small Dust Particles Can Affect The Imaging Quality Of The Lenses, So They Also Need To Be Produced In Clean Workshops; Precision Machinery Manufacturing, Such As High-end Watches And Precision Bearings, Also Relies On Clean Workshops To Prevent Metal Debris And External Dust Generated During The Processing From Affecting Product Accuracy And Performance.
