ຄວາມສຸດສະຫຼັບຂອງ VAE Emulsion: ການໃຊ້ເທียບກັບການເປັນການການການການ

VAE emulsion ເປັນໄປ່ອນຫຼາຍກວ່າ adhesives ບໍລະຄາສຳລັບໃຊ້ນ້ຳໃນຫຼາຍດ້ານ. ບໍ່ເທົ່າກັບ water-based adhesives ທົ່ວໄປ, VAE emulsion ເຫຼົ່າງມີຄວາມແຂງແຮງກວ່າຕໍ່ non-porous substrates ຄຳແນວ່າ PVC, metal, ແລະ glass ບໍ່ຕ້ອງການ primers, ໂດຍໄດ້ຮັບຄວາມຊ່ວຍເຫຼືອງຈາກ ethylene segments ທີ່ເພີ່ມຄວາມ wetting properties. มັນສະແດງຄວາມ:flexibility ຂູ່, ນຳໜັກ 300% ໃນການເສຍໄປ, ສະແດງວ່າມັນແມ່ນ ideal for applications ທີ່ຖືກ subject to movement, ຄຳແນວ່າ construction joints. VAE emulsion ອີງຢູ່ minimum film-forming temperature (MFFT) ທີ່ຕ່ຳກວ່າ, forming continuous films at 5–10°C, whereas some water-based adhesives struggle to cure at low temperatures. In outdoor use, VAE emulsion resists UV degradation ແລະ water absorption ຕັ້ງແຕ່ການເປີດແຜງ, maintaining bond strength after prolonged exposure. For example, in tile adhesives, VAE emulsion ensures durable bonds on concrete substrates, while standard water-based adhesives may fail in humid environments. However, water-based PVA adhesives excel in water solubility and cost-effectiveness for temporary bonding, while VAE emulsion dominates in durability and versatility.
