Ɔhyew & Viscosity Attenuation a PTFE Ɔhyew a Ɛkorɔn Teyp

Jiangsu Aokai New Materials, adwumayɛfo a wɔyɛ PTFE high-temperature tape, kyerɛkyerɛ adwumayɛ mu nsakrae akyi mpɛn pii oven use.The attenuation of temperature resistance and holding viscosity mainly lies in the adhesive layer , mmom sen PTFE substrate. PTFE substrate no molecule nhyehyɛe no gyina hɔ pintinn yiye na ɛkame ayɛ sɛ ennyin nsen 260°C. Nea ɛne eyi bɔ abira no, nneɛma a wɔde ntama a ɛyɛ hyew te sɛ silicone no fa thermo-oxidative onyin mu wɔ ɔhyew a wɔtaa yɛ no ase, na awiei koraa no ɛkyerɛ PTFE teyp a ɛyɛ hyew kɛse no nkwa nna.

1. Attenuation Mmara a ɛfa Ɔhyew a Ɛko Tia Ho

Fononoo mu hyew a ɛfata (≤ 260°C) Ntama a wɔde nkata so no nyin nkakrankakra, na ɔhyew a wɔfrɛ no no so tew afe biara. Ne bere tenten som nkwa nna bɛyɛ mfe 1–3.
