*PQ AB750: High-Performance Anti-Blocking Silica for Plastic Films
PQ AB750, umkhiqizo we-silica ophumile we-PQ Corporation (USA), usebenza ikakhulukazi njengomkhiqizo ophikisana nokubamba amafilimu epulasitiki. Ivinjwa ukuhlanganiswa kwezingqimba ngokwakha ama-protrusions amancane ebusweni befilimu ngenkathi ithuthukisa izici zokuhamba nokusebenza. Nansi isithombe esinemininingwane ngezici zayo, izspecifications zobuchwepheshe, izicelo eziphansi, kanye nezinzuzo zemboni.
I. Product Basics
1. Chemical Composition & Manufacturing Process
• Composition: Mainly composed of amorphous silica (SiO₂) with a purity ≥99%, containing trace metal oxides (e.g., Na₂O, Fe₂O₃).
• Process: Produced via the precipitation method, where sodium silicate (water glass) reacts with sulfuric acid to form a precipitate, which is then washed, dried, and surface-treated (Source: Eastmoney).
• Surface Treatment: Typically modified with organosilane (e.g., fatty acid esters) to enhance compatibility with plastic resins and reduce dispersion difficulty.
2. Izakhiwo Zomzimba & Izincazelo
• Appearance: Umhlophe uthuli, ngaphandle kokubonakala kokungcoliswa.
• Particle Size: Average particle size (D50) of approximately 7–10 μm, with a narrow distribution 可调 (adjustable via classification) to suit different film thickness requirements (Source: X-Technology Patent).
• Specific Surface Area: 150–200 m²/g (BET method), ensuring high adsorption and anti-blocking efficiency.
• pH Value: 6.5–7.5 (neutral), safe for non-reactive interaction with film materials.
• Density: ~2.0 g/cm³, bulk density 0.2–0.4 g/cm³, facilitating metering and dispersion.
II. Izigaba Eziyinhloko Zobuchwepheshe
1. Anti-Blocking Performance
• Mechanism: AB750 ibhujiswa phezulu kwefilimu ngesikhathi sokucubungula, kwakha ukuphakama okungama-micron okuphazamisa amandla e-van der Waals phakathi kwezendlalelo futhi avimbele ukujolisa (Umthombo: Iphatent ye-X-Technology).
• Izibalo Ezinembile:
◦ Coefficient of Friction (COF): Reduces from 0.8–1.2 to 0.2–0.4, significantly improving slip.
◦ Opening Force: For PE films with 0.5–1.5% AB750, opening force ≤5 N/15 mm, meeting high-speed packaging line requirements.
2. Ukusabalala & Ukuqina Kwenqubo
• Masterbatch Compatibility: Easily compounded with PE, PP, and other resins into masterbatches, ensuring uniform dispersion in extrusion and avoiding surface defects from agglomeration.
• Thermal Stability: Stable at processing temperatures of 200–250°C, with no decomposition or volatilization, suitable for high-temperature extrusion.
3. Izinhlobo Zokukhanya Nezobuchwepheshe Ezilinganayo
• Transparency: Maintains high film transmittance (≥90%) via controlled particle size distribution, ideal for clear packaging films.
• Mechanical Impact: Minimal effect on tensile/tear strength at recommended loadings (≤2%); may even enhance puncture resistance in some formulations.
III. Izicelo Zaphansi
1. Ukukhiqiza Ifilimu Yezinto Zokwenziwa
• Izicelo Eziyinhloko:
◦ Ukupakishwa Kfood: PE cling film, PP shrink film ukuvimbela ukuhlanganiswa ekupakisheni inyama/ukubhaka.
◦ Izikhwama Zezolimo: Inciphisa ukujolisa ezikhwameni ze-PE, ithuthukisa ukusebenza kahle kokufakwa emasimini.
◦ Industrial Packaging: Stretch wrap and heavy-duty bags for enhanced stackability.
• Izinhlobo Zefilimu Ezivamile:
◦ LDPE: 0.5–1.0% ukungezelela kokupakisha okujwayelekile.
◦ BOPP: 0.8–1.5% yezi zifilimu nezinto ezisekelayo ze-tape.
◦ LLDPE: 0.3–0.8% yezi ezinzima kakhulu (Umthombo: Shunqi Network).
2. Fibers & Masterbatches
• Ukuguqulwa Kwefiber: Ivimbela ukuhlanganiswa kuma-fiber e-PP (isb., i-spunbond nonwovens), ithuthukisa ukuvumelana kwe-web.
• Functional Masterbatches: Blended with slip agents (e.g., oleamide) to create anti-blocking masterbatches for direct resin addition.
3. Ezinye Izicelo Zezimboni
• Imikhiqizo yeRubber: Njengomsebenzi wesibili wokuphakamisa ukuhamba phezulu kumatubhu e-silicone nasezikhwama.
• Coatings & Inks: 0.5–1% addition improves anti-blocking in UV-curable coatings (Source: Eastmoney).
IV. Izinzuzo Zezimboni & Ukuhambisana
1. Izinzuzo Zokusebenza
• Izindleko-Ezisebenzayo: 30–50% izindleko eziphansi kune fumed silica, efanelekile ezinhlelweni zezimboni ezinkulu.
• Batch Consistency: PQ’s global manufacturing ensures reliable quality, minimizing production risks.
2. Ukuhambisana Nezomthetho
• Ukuphepha Kokuxhumana Nokudla: Kuhambisana ne-FDA 21 CFR §177.2420 (ama-filimu okupakisha ukudla) kanye nemithetho ye-EU EC No 10/2011 yeplastiki.

• Case 2: Agricultural Film
◦ Customer Pain Point: Traditional mulch films suffered from adhesion, slowing field deployment and increasing tear rates.
◦ Ukuphuculwa: 1.2% AB750 kwiifilimu ze-LDPE zikhuphe ukuncamathela, zaphucula amandla okudlula ngama-10%, kwaye zanda ubomi benkonzo ngama-15%.
