INDUSTRIAL X-RAY FIXER
Industrial Fixer
Professional Industrial Fixer is the matched core chemical for industrial wet X-ray film post-processing, dedicated to dissolving unexposed silver halide crystals and permanently fixing radiographic image layers to avoid later fading. Equipped with exclusive deodorizing formula technology, this industrial fixer greatly cuts strong irritating chemical odor, optimizes closed darkroom workshop environment and effectively protects long-term operating staff’s respiratory health. Three independent fixing formulas are provided to perfectly match supporting industrial developer, covering manual room-temperature operation, high-temperature automatic machine assembly line and mixed manual & machine universal production scenarios, with stable compatibility for all mainstream industrial NDT X-ray films to meet high-frequency flaw detection production demands.
Core Product Advantages
Adopts low-irritation deodorized formula to eliminate pungent volatile gas, greatly improving workshop air quality and working comfort. It features fast clearing speed and thorough fixing capacity, forming stable image layers that will not fade after long-term storage of radiographic negatives.
The concentrated liquid maintains excellent dilution stability, suitable for long-cycle continuous industrial mass production and reduces frequent liquid replacement cost. Perfectly matched with supporting industrial developer, the whole chemical system delivers unified, consistent film imaging quality for weld inspection, casting flaw detection and PCB plate making film processing.

Three Standard Fixing Processing Formulas
1. Room Temperature Manual Processing Formula
Low volatile formula specially developed for darkroom manual operation, with moderate fixing speed, easy to control for daily manual film sorting, trimming and filing work in small and medium inspection workshops.
| Chemical Product | Dilution Ratio | Temperature | Processing Time |
|---|---|---|---|
| Matched Industrial Developer Concentrate | 1:3 (liquid : water) | Ambient room temperature | 120 ~ 300 seconds |
| Industrial Fixer Concentrate | 1:3 (liquid : water) | Ambient room temperature | 120 ~ 300 seconds |
2. High-Temperature Rapid Automatic Machine Formula
High temperature resistant fixing formula designed for continuous automatic film processor production lines. Supporting stabilizer B liquid effectively slows down liquid aging and reduces solution replacement frequency under long-time uninterrupted mass production.
| Chemical | Dilution Ratio | Temp Range | Time | Replenishment Volume |
|---|---|---|---|---|
| Machine Developer A Liquid | 1:3 | 20 ~ 38°C | 120 ~ 300s | 300 ~ 450ml per square meter |
| Machine Fixer A Liquid | 1:3 | 20 ~ 38°C | 120 ~ 300s | 300 ~ 450ml per square meter |
3. Universal Dual-Purpose Formula (Manual & Machine Shared)
Integrated all-in-one fixer without extra auxiliary stabilizer liquid, simplifying chemical inventory storage and daily operation management. Cost-effective for comprehensive industrial inspection factories with mixed manual and automatic processing lines. Small 1L portable bottles are available for small-batch production to avoid unused liquid waste after opening.
| Chemical | Dilution Ratio | Temp Range | Time | Replenishment Volume |
|---|---|---|---|---|
| Universal Industrial Developer | 1:3 | 18 ~ 38°C | 120 ~ 300s | 100 ~ 200ml per square meter |
| Universal Industrial Fixer | 1:3 | 18 ~ 38°C | 120 ~ 300s | 100 ~ 200ml per square meter |
Optional Industrial Fixer Powder
Solid fixer powder is developed to solve cross-border liquid dangerous goods transportation and customs clearance restrictions. Compact packaging greatly reduces logistics weight and cost for long-distance overseas shipments. Operators only need to mix the powder with clean water on site, and the fixing performance is fully consistent with concentrated liquid. Standard packaging: 1kg per bag, 10 bags per carton.
Storage & Operation Safety Precautions
Sealed concentrated fixer must be stored in cool, light-proof environment away from high temperature. Fixing solution containers must be completely separated from developer containers to prevent cross-contamination of raw chemicals.
All liquid preparation and film fixing work must be carried out in ventilated space. Operators must wear complete protective gloves, goggles and masks to avoid inhaling chemical vapor or direct skin/eye contact with concentrated liquid.
Darkroom safelight standard: Adopt 15W frosted bulb equipped with deep red filter, maintain a minimum distance of 1.2 meters between light source and film to prevent premature fogging and defective radiographic negatives.
Frequently Asked Questions
Q1: Why is this industrial fixer designed with deodorized formula?
A: Most industrial flaw detection darkrooms are semi-closed with poor natural ventilation. The low-odor formula cuts harsh chemical volatile smell, improves overall workshop working environment and reduces long-term respiratory discomfort risk for on-site technicians.
Q2: What is the function of B stabilizer liquid matched with machine-type industrial fixer?
A: B liquid acts as special anti-oxidation stabilizer, it slows down chemical aging of diluted fixer working solution, extends replacement cycle and guarantees uniform stable fixing effect during uninterrupted continuous machine production.
Q3: Can industrial fixer powder and developer powder be mixed together in storage or preparation?
A: Mixing is strictly forbidden. Developer and fixer belong to completely different chemical systems, mixing will trigger invalid chemical reaction, lose respective processing functions and even cause permanent damage to industrial radiographic films.
