U procesu proizvodnje od petoslojni koekstrudirani zaštitni film , kako kontrolirati temperaturu taljenja svakog sloja smole i temperaturne parametre ekstrudera i glave kalupa?
Glavni materijali petoslojne koekstrudirane zaštitne folije uključuju poliamid (PA), polietilen (PE), polipropilen (PP) i poseban ljepljivi sloj (TIE), od kojih svaki ima svoju specifičnu temperaturu taljenja i karakteristike obrade. Changxi Packaging Technology implements strict standards in the screening and auditing of raw material suppliers to ensure that the purchased resin raw materials are of high purity and good batch-to-batch stability, which is the prerequisite for achieving precise temperature control. The company understands its melting behavior through detailed performance testing of raw materials and provides data support for subsequent temperature setting.
Strategija kontrole temperature topljenja
Slojevita postavka temperature topljenja:
PA sloj: poliamid ima višu temperaturu taljenja, obično između 230-260°C, ovisno o modelu i sadržaju aditiva. Changxi Company uses a precise temperature control system to ensure that the PA resin is completely melted during the extrusion process while avoiding degradation caused by overheating.
PE sloj: Temperatura taljenja polietilena je relativno niska, općenito između 120-140°C. The company precisely adjusts the melting temperature according to the specific type of PE (such as LDPE, HDPE, etc.) to ensure good fluidity while maintaining physical properties.
PP sloj: Temperatura taljenja polipropilena je obično 160-170°C. The company will flexibly adjust the temperature according to the reinforcement level and modification of PP to ensure its stability and strength during extrusion.
TIE sloj: Kao ljepljivi sloj, temperatura topljenja TIE materijala mora odgovarati susjednim slojevima kako bi se osiguralo dobro međuslojno spajanje. Through in-depth material research, Changxi Company selects TIE resin with a wide processing window to ensure good bonding over a wide temperature range.
Comprehensive control: The company uses advanced temperature control systems to independently and precisely control the melting temperature of each layer to ensure that each layer of material can be fully melted during extrusion and maintain the best physical and chemical properties.
Optimizacija parametara temperature ekstrudera i kalupa
Extruder temperature setting: The temperature setting of the extruder needs to take into account the melting characteristics of the resin, the screw design, and the extrusion speed. Tvrtka Changxi usvaja segmentiranu tehnologiju kontrole temperature, postavlja više zona grijanja duž duljine vijka i postupno povećava temperaturu u skladu s karakteristikama protoka i zahtjevima zagrijavanja smole kako bi se osiguralo ravnomjerno topljenje i stabilna isporuka smole u vijku.
Podešavanje temperature kalupa: Temperatura kalupa ključna je za morfologiju ekstruzije, ujednačenost debljine i kvalitetu površine filma. The company accurately sets the temperature of each area of the die according to the width, thickness and material characteristics of the film to ensure that the molten resin maintains appropriate fluidity and viscosity at the die outlet, thereby obtaining high-quality, defect-free films.
Changxi Packaging Technology uses advanced automated control systems to monitor and record the temperature data of the extruder and die in real time, and automatically adjusts the output of the heating element through a closed-loop feedback mechanism to ensure that the temperature is stable within the preset range. The company is also equipped with high-precision temperature sensors and infrared thermometers to monitor the molten resin and extrusion process at multiple points, promptly detect and correct any temperature deviations, and ensure the continuity and stability of the production process.
