Sintrad porös polyeten (PE) -filter med stark syremotstånd

TOPTITECH's Sintered Porous Polyethylene (PE) Filter With Strong Acid Resistance is a precision-engineered, monolithic filtration component fabricated via controlled thermal sintering of ultra-high-molecular-weight polyethylene (UHMWPE) powder. This 200mm-long, closed-end tubular filter features a pore gradient structure with 1-2μm Nominell filtreringsnoggrannhet, uppnås genom optimerad partikelstorleksfördelning (PSD) och sintringsprotokoll med flera steg samtidigt som mekaniska stabiliteter är upp till 6 bar (vid 25 grader) .} uhmwpe-utställningen UPPLIKTER, KELISKA KELISKA KEMISKA KELISKA KELISKA KELISKA KEMPOLERING, COSTERING ASSOTERING ASSOTERING ASSOTERING ASPOTERING (e.g., 98% H2SO4), alkalis (e.g., 40% NaOH), and organic solvents, validated by ASTM D543 and ISO 175 compatibility testing.

Designed for high-purity applications, the Sintered Porous Polyethylene (PE) Filter With Strong Acid Resistance operates within a thermal range of -40°C to 116°C (intermittent), maintaining structural integrity via cross-linked polyethylene chains (C-C bond energy: 346 kJ/mol). Its hydrophobic surface (contact angle >120℃) minimizes liquid absorption, while the tortuous, interconnected pore network achieves 85-92% porosity for flow rates up to 12 L/min·cm² at ΔP=1 bar. Critical in pharmaceutical catalyst recovery and semiconductor electrolyte purification, this filter complies with USP Class VI and FDA 21 CFR 177.1520 Standarder, säkerställer ultra-low extrahables (<0.1% TOC) and non-fiber-releasing performance under MIL-STD-282 test conditions.

Produktfunktioner

 

 

Precision Filtration Performance‌

The Sintered Porous Polyethylene (PE) Filter achieves 1-2μm filtration accuracy through gradient sintering of UHMWPE particles with optimized size distribution (D50: 15-25μm). This monolithic structure eliminates fiber shedding risks, ensuring USP Class VI-compliant purity for pharmaceutical and Bioprocesseringsapplikationer .

Oöverträffad kemisk inerthet‌

Engineered with cross-linked polyethylene chains (CC bond energy: 346 kJ/mol), the filter resists concentrated acids (98% H₂SO₄), alkalis (40% NaOH), and aggressive solvents (e.g., DMSO, acetone), validated by ASTM D543 and ISO 175 chemical compatibility testar .

Termisk stabilitet under extrema förhållanden‌

UHMWPE -matrisen upprätthåller strukturell integritet över -40 grad till 116 grader (intermittent), med tryckbetyg upp till 6 bar vid 25 grader . HDPE -varianter motstår kontinuerlig 82 -graders operationer, stödd av en termisk deormation av 0 . 5% 6 60 -examen.

 

 

Höga flödeshastigheter med förlängd livslängd‌

A tortuous pore network (85-92% porosity) enables flow rates up to 12 L/min·cm² at ΔP=1 bar. The hydrophobic surface (contact angle >120 grader) minimerar fouling, medan gas-vätska reversibel backflushing återställer 98% initial permeabilitet efter 500+ cykler .

Anpassningsbar ytfunktionalitet‌

Tre ytändringar adresserar olika tillämpningar:

Hydrofil (kontaktvinkel<30°) for aqueous solutions

Hydrophobic‌ (contact angle >120 grader) för gasfiltrering

Självtätning‌ Varianter som blockerar vätskepenetration över 0 . 3 bar, idealisk för medicinska kontrollventiler.

Regleringsöverensstämmelse för kritiska industrier‌

Filtret uppfyller FDA 21 CFR 177.1520 och MIL-STD -282 standarder, vilket levererar ultra-låga extraherbarabler (<0.1% TOC) and non-pyrogenic performance, essential for semiconductor ultrapure water (UPW) and vaccine production.
