1. Product Introduction
Cleanroom wiping paper is a high-performance cleaning consumable specially designed for clean environments. It is widely used in electronics manufacturing, optical instruments, medical devices, precision machinery, and other fields with strict dust-free requirements. Its core function is to efficiently remove surface contaminants while preventing fiber shedding or secondary contamination, thus ensuring the cleanliness of the production environment and product yield.
2. Material and Process Standards
-
Material Composition:
The wiping paper adopts a nonwoven composite structure made of 45% polyester and 55% wood pulp fibers. -
Polyester fibers: Provide high strength, chemical resistance, wear resistance, and tear resistance, reducing fiber shedding during wiping.
-
Wood pulp fibers: Enhance liquid absorption and softness, improving the adsorption of fine particles.
-
Basis Weight (GSM):
The unit weight ranges between 56-68 g/m², classified by application scenarios:-
Standard type (56-60 g/m²): General wiping for routine cleaning.
-
Enhanced type (61-68 g/m²): For high absorption needs or heavily contaminated scenarios.
-
3. Physical Performance Requirements
| Test Item | Test Standard | Qualification Criteria |
|---|---|---|
| Tensile Strength (MD) | GB/T 24218.3 | Must meet customer requirements |
| Absorption Rate (DI Water) | GB/T 24218.6 | Must meet customer requirements |
| Fiber Shedding | IEST-RP-CC004.3 | Must meet customer requirements |
| Abrasion Resistance (Dry) | ASTM D3886 | Must meet customer requirements |
4. Chemical Cleanliness Standards
Cleanroom wiping paper is generally produced in Class 10,000 cleanrooms and is not washable. It is suitable for lower cleanliness or peripheral cleanroom use. For environments requiring Class 10,000 or better cleanliness, cleanroom wipes are recommended, which can meet up to Class 10 cleanliness.
5. Packaging and Labeling Specifications
-
Packaging Formats:
-
Roll form: Also called jumbo roll wiping paper, with 500 sheets per roll, convenient for pull-out use.
-
Bagged form: Also known as 0609 wiping paper, individually sealed packages containing 150-1200 sheets depending on size.
-
-
Color Coding:
White, blue, and green are common colors. In electronics, white is more widely used, while blue and green are more common in industrial wiping scenarios. In China, white is predominant, whereas blue and green are more popular in Europe and America.
6. Testing and Certification
Customers can request RoHS certification and TDS (Technical Data Sheet) reports from suppliers to ensure compliance.
7. Application Guidelines
-
Electronics Industry:
Recommended use with IPA solvent for wiping PCB boards; single sheet single-direction wiping is advised. -
Optical Field:
Prefer blue-colored microfiber laminated products to avoid scratching coated surfaces. -
Medical Sterilization:
Compatibility verification with EO/γ-ray sterilization is required; packaging materials must comply with YY/T 0698.2.
Summary:
Standardized production and scientific selection of industrial cleanroom wiping paper are crucial to maintaining modern industrial cleanliness. Users are advised to choose wiping papers based on actual scenario requirements, considering material properties, cleanliness level, and packaging formats, while regularly verifying suppliers’ test reports and compliance documentation.
