Impact on Poly(Vinyl chloride) of trimethoprim schiff bases as stabilizers

Polymers and Polymer Composites, 2022
Poly(vinyl chloride) PVC materials are used in many industrial and household outdoor applications which exposed to sunlight ultraviolet. This exposure motivates photo-degradation of the PVC and hence, reduces its life time and leads to undesirable ...

Self‐Powered Bearing Sensing and Real‐Time Fault Diagnosis Enabled by Non‐Invasive Triboelectric Sensors and Edge AI Acceleration

Advanced Science, EarlyView.
This study achieves the synergistic integration of self‐powered sensing and edge AI acceleration to establish a real‐time fault diagnosis system. The proposed TENG‐based self‐powered bearing sensor (NSE‐TBS) and FPGA‐accelerated edge AI framework fundamentally break through the inherent limitations of conventional monitoring systems, including complex ...

Development of PVC films, resistant mold influence [PDF]

E3S Web of Conferences, 2019
Along with the use of plasticizers in the development of polymeric materials with specific properties, special substances such as fungicides are also used because of the negative impact on the polyvinyl chloride materials of microorganisms. In the present work, the possibility of practical application of butylbutoxyethyl phthalate (BBOEP) and ...

THE PHENOMENON OF PVC FILM DEFORMATION, NAMELY WAVINESS OF PVC FILM CAUSED BETWEEN TWO SOFT PVC FILMS FORMED BY DIFFERENT COMPOUNDS. CHAPTER I INFLUENCE OF RAW MATERIALS

NIPPON GOMU KYOKAISHI, 1965
異種配合の軟質塩化ビニルフィルム二層間において起る変形現象について物理的な影響を観察し次の知見をえた.1) フィルムの厚みの影響.シートと同種の可塑剤 (DOP) の場合, 厚みの影響はほとんどあらわれていないが, DBPの場合はフィルムの厚みが厚いほどDBPの移行は少なくなっている.2) 塩化ビニル樹脂に他の樹脂をブレンドした場合, 市販品の各樹脂をブレンドしたが, 30%以下のブレンドでは, ほとんど効果がなかった.3) 二枚の塩化ビニルフィルム (またはシート) 問に異種の樹脂フィルム各種をそれぞれ挿入した場合, 0.03mm程度のフィルムの挿入ではほとんど効果はなかった.4) 塩化ビニルフィルムの加工条件の差.加工条件はかえてみても一定の傾向はえられなかった.

Self‐Adaptive Non‐Flammable Wallpaper With Layered Bead‐Network Structure for Light Path Modulation Enabling on‐Demand Building Thermal Management

Advanced Science, EarlyView.
A layered bead‐network wallpaper is designed to modulate the light propagation path, overcoming the color residue limitations of thermochromic components for efficient automatic switching between radiative cooling and solar heating modes. The layered bead‐network wallpaper provides passive, all‐season thermal regulation while offering self‐cleaning and

Photostabilizing Efficiency of Poly(vinyl chloride) in the Presence of Organotin(IV) Complexes as Photostabilizers

Molecules, 2016
Three organotin complexes containing furosemide as a ligand (L), Ph3SnL, Me2SnL2 and Bu2SnL2, were synthesized and characterized. Octahedral geometry was proposed for the Me2SnL2 and Bu2SnL2, while the Ph3SnL complex has trigonal bipyramid geometry.
