Recently, Baoshili‘s semiconductor-grade ultra-clean PFA fitting “1/2” butt-weld tee” successfully passed performance tests including roughness and metal ion leaching, meeting SEMI F57 specifications. As a key model in the company’s semiconductor-grade PFA fitting product lineup, it not only marks Baoshili’s breakthrough in the field of high-purity fluid core components but also supports the company in building an integrated solution for semiconductor-grade chemical delivery systems.

In advanced manufacturing processes, metal contamination control has become a critical factor determining chip performance. Ultra-pure PFA materials are core components for chemical delivery in semiconductor front-end manufacturing. Baoshili's 1/2" ultra-clean PFA butt-weld tee features ultra-high cleanliness and excellent acid/alkali resistance. It forms a T-shaped connection, facilitating the distribution or convergence of multi-path fluids, and is widely used in complex pipeline systems for semiconductor manufacturing.

Through proprietary patented manufacturing processes, the product has achieved breakthroughs in multiple indicators:

Ultra-Low Metal Ion Leaching

Metal contamination can alter the electrical properties of microelectronic devices and cause corrosion or etching on key surfaces during manufacturing, leading to device failure. The metal ion leaching levels of Baoshili's 1/2" ultra-clean PFA butt-weld tee—including aluminum (Al), arsenic (As), antimony (Sb), cadmium (Cd), chromium (Cr), copper (Cu), iron (Fe), lead (Pb), lithium (Li), magnesium (Mg), manganese (Mn), nickel (Ni), sodium (Na), titanium (Ti), tin (Sn), vanadium (V), and zinc (Zn)—all meet SEMI F57 standards, satisfying the extreme contamination control requirements of advanced processes.


Ultra-Smooth Inner Wall

With an inner surface roughness of Ra ≤ 0.35μm, it prevents fluid retention and scaling, reducing contamination risks.

High Temperature Resistance

It maintains stable chemical properties within a temperature range of -40℃ to 260℃.

Corrosion Resistance

It resists corrosive chemicals such as strong acids (hydrofluoric acid, nitric acid) and strong alkalis (ammonia water), with no metal migration over long-term use.

Integrated Hot-Melt Welding

The ultra-clean PFA fitting forms a molecular-level bond with ultra-clean PFA pipes through hot-melt welding, creating a complete chemical delivery system and ensuring the purity and stability of semiconductor manufacturing processes.

Currently, only a few domestic enterprises have developed semiconductor-grade ultra-pure fluoropolymer products. Through independent R&D, Baoshili has overcome key technologies such as high-purity material purification and precision molding, successfully launching semiconductor-grade products including the 1/2" ultra-clean PFA butt-weld tee and multiple models of ultra-clean PFA pipes, which are widely used by leading semiconductor enterprises.

As the global semiconductor industry advances into the 3nm era, "nanoscale contamination control" in chemical delivery systems has become a critical bottleneck restricting yield rates. Baoshili is continuously increasing R&D investment in high-purity fluoropolymer products and actively collaborating with industry partners to formulate the group standard Semiconductor-Grade Ultra-Pure Melt-Processible Polytetrafluoroethylene (PFA) Pipes, aiming to accelerate the development of domestic semiconductors.

If you're looking to reduce noise in your space, whether for a home office, recording studio, or commercial setting, acoustic panels are an excellent solution. But one of the most common questions we hear is:
“How many acoustic panels do I need to soundproof a room?”

At Guangdong Liyin Acoustics Technology Co., Ltd.( Leeyin ) , we specialize in high-performance wooden slat acoustic panels, and we’re here to help you make the right decision for your acoustic project.

---

🎯 Understanding the Purpose of Acoustic Panels

Before calculating quantity, it's essential to understand that acoustic panels absorb sound—they don’t completely block it like traditional soundproofing materials. They’re primarily used to:

• Minimize echo and reverberation

• Improve sound clarity

• Reduce noise levels within a room

For full soundproofing, a combination of materials (mass-loaded barriers, insulation, and sealing gaps) may be required. However, strategically placing acoustic panels significantly improves perceived sound quality and reduces noise transmission.

---

📏 How to Calculate the Right Number of Acoustic Panels

Here’s a basic step-by-step guide:

1. Measure the Room Size

Determine the length × width × height of your room to get the total cubic space.

2. Calculate Wall Surface Area

Focus on the four walls (and ceiling if needed). Remove doors/windows from your calculation.

3. Determine Coverage Percentage

Depending on the purpose, typical coverage recommendations are:

4. Standard Panel Size Reference

At Liyin Acoustics, our standard wood slat acoustic panel is typically:

• Width: 600 mm (23.6")

• Height: 2400 mm (94.5")

• Coverage Area per Panel: ~1.44 m²

For example:
If you want to cover 12 m² of wall space, you would need approximately 8–9 panels.

---

🧠 Expert Tip: Placement Is Just as Important

Rather than covering 100% of the walls, strategic placement helps maximize performance:

• First reflection points (side walls)

• Back wall and front wall (behind speakers or workspace)

• Ceiling if echo is still present

When working in hazardous environments—such as oil refineries, mining sites, or chemical plants—lighting isn’t just about visibility; it’s about safety. A common question that arises is: “Is an IP67 LED Work Light explosion proof?” While IP67-rated lights are highly durable and water-resistant, it's essential to understand what "explosion proof" truly means before making safety-critical decisions.

Understanding IP67 and Explosion Proof Standards

An IP67 LED Work Light is designed to withstand dust intrusion and water immersion up to 1 meter for 30 minutes. This makes it ideal for outdoor use, wet environments, and heavy-duty applications. However, IP67 alone does not mean the light is explosion proof.

Explosion proof lighting must comply with rigorous safety standards such as ATEX or UL844. These lights are engineered to contain sparks or flames within the housing, preventing ignition of flammable gases or dust in explosive zones. While an IP67 explosionproof LED Work Light combines both water/dust protection and explosion containment features, not all IP67-rated lights are certified for explosive atmospheres.

Choosing the Right LED Work Light for Hazardous Areas

If you're operating in a high-risk environment, always check for proper explosion-proof certification in addition to IP ratings. Some manufacturers design dual-rated products that serve both purposes, providing waterproof performance and certified explosion safety. A standard LED Work Light may offer high brightness and durability but could fail safety requirements in zones classified as hazardous.

🎧 What Do Acoustic Panels Do?

Acoustic panels absorb sound waves to reduce noise, echo, and reverberation. They are ideal for:

• Home theaters

• Offices

• Studios

• Conference rooms

• Bedrooms

Panels like our E0 MDF + PET felt wooden slat acoustic panels are designed to combine visual appeal with powerful acoustic performance.

---

🤔 Is There Such a Thing as “Too Much”?

Yes. Too many acoustic panels can lead to an unnatural, overly “dead” room where sound becomes flat and lifeless. This is especially true in:

• Studios where natural reverberation is needed

• Living spaces where sound dynamics should feel natural

• Rooms with limited volume, where too much absorption can dull conversation and music

---

⚖️ Striking the Right Balance

When planning an acoustic treatment, consider these principles:

1. Coverage Ratio

A general recommendation is to cover 15–30% of the room’s surface area with acoustic panels. This can vary depending on the use case (e.g., recording studio vs. living room).

2. Panel Placement

More important than quantity is placement. Focus on:

• First reflection points

• Rear walls

• Ceiling above listening areas

• Corners for bass traps

Liyin’s PET-backed acoustic panels offer flexibility in installation—glue, screw, or mounting systems—so you can place them exactly where needed.

3. Room Purpose

Ask yourself: Are you aiming to reduce echo or completely deaden the space? The goal should dictate how many panels you actually need.

---

🎧 Why Panel Spacing Matters

Most people assume acoustic panels should be mounted flat against the wall. While that’s common, leaving a small air gap behind the panel can significantly improve low-frequency absorption. This method is often used in professional sound treatment applications.

---

📏 Ideal Spacing: The Magic Number

In general, 2 to 4 inches (5–10 cm) of space behind the panel is ideal. This added distance:

• Enhances bass absorption

• Improves overall sound dampening

• Increases absorption without additional material

💡 Pro Tip: A 2-inch panel with a 2-inch air gap performs nearly as well as a 4-inch panel flat-mounted.

---

🛠️ How to Mount Panels with a Gap

Here are three popular methods to mount wood slat acoustic panels with air space:

1. Wooden Furring Strips: Use wood strips to create a frame behind the panel.

2. Wall Spacers: Install metal or plastic standoffs to keep the panel off the wall.

3. French Cleat System: Great for adjustable mounting with gap control.

Our Liyin panels are engineered to be easy to install with all three methods—gluing, screwing, or using brackets.

At Guangdong Liyin Acoustics Technology Co., Ltd. ( Leeyin ) , we specialize in wood slat acoustic panels and deliver effective sound solutions to clients worldwide. In this guide, we’ll walk you through how to soundproof a room as completely as possible, whether for a studio, office, or private space.

---

🔍 Understanding True Soundproofing

Soundproofing is different from sound absorption. Soundproofing blocks sound, while acoustic treatment improves sound quality inside the room.

To soundproof a room, you must address all sound pathways:

• Airborne sound (voices, music)

• Impact sound (footsteps, vibrations)

• Structural transmission (through walls, floors, ceilings)

---

✅ 1. Seal All Air Gaps

Even the smallest gaps let sound leak in or out. Start by sealing:

• Door frames: Use door sweeps and rubber seals

• Window edges: Apply acoustic caulk or double-glazed windows

• Outlets and vents: Cover with soundproofing gaskets or acoustic putty pads

🔧 Use acoustic caulk to seal all perimeter gaps for added noise isolation.

---

✅ 2. Upgrade Your Walls

Typical drywall transmits sound easily. To soundproof walls:

• Add mass: Use mass loaded vinyl (MLV) or multiple layers of drywall with Green Glue (a damping compound)

• Use decoupling techniques: Install resilient channels or staggered studs

• Install high-density acoustic panels, like our PET-backed wood slat acoustic panels for added absorption and diffusion

👉 Liyin Acoustics' slat wall panels not only enhance aesthetics but contribute to a multi-layered acoustic barrier.

---

✅ 3. Reinforce Doors & Windows

Standard doors and windows are weak spots.

• Replace hollow-core doors with solid-core doors

• Install double or triple-glazed windows

• Use soundproof curtains or acoustic window inserts

---

✅ 4. Soundproof the Ceiling

To prevent noise from above:

• Add acoustic insulation between ceiling joists

• Use acoustic ceiling panels or suspended ceiling systems

• Install wooden acoustic ceiling panels from Liyin Acoustics for both style and performance

---

✅ 5. Treat the Floors

To block footstep noise and vibration:

• Lay carpet with dense underlay

• Use soundproofing mats or cork/rubber flooring

• Seal baseboards with acoustic sealant

---

✅ 6. Add Absorption Materials

To control echo and improve internal acoustics:

• Install Liyin’s wood slat acoustic panels

• Use fabric acoustic panels, bass traps, or corner diffusers

• Add acoustic foam in key reflection points
