ຄຸນລັກສະນະການນໍາໃຊ້ຂອງທໍ່ເສັ້ນໄຍແກ້ວ epoxy
ຄຸນລັກສະນະການນໍາໃຊ້ຂອງທໍ່ເສັ້ນໄຍແກ້ວ epoxy:
1. Various methods. Various resins, curing agents, and modifier systems can simply adapt to the requirements of various applications, and their scale can range from extremely low viscosity to high melting point solids.
2. Convenient curing. Using various curing agents, the epoxy resin system can be cured within a temperature range of 0~180℃.
3. ການຍຶດເກາະທີ່ເຂັ້ມແຂງ. ການມີຢູ່ຂອງ polar hydroxyl ແລະ ether bond [1] ປະກົດຂຶ້ນຢູ່ໃນລະບົບຕ່ອງໂສ້ໂມເລກຸນຂອງ epoxy resin ເຮັດໃຫ້ມັນມີຄວາມຍຶດຫມັ້ນສູງກັບສານຕ່າງໆ. ການຫຼຸດລົງຂອງ epoxy resin ແມ່ນຕ່ໍາໃນເວລາທີ່ການປິ່ນປົວ, ແລະຄວາມຄຽດພາຍໃນທີ່ສ້າງຂຶ້ນແມ່ນຂະຫນາດນ້ອຍ, ເຊິ່ງຍັງຊ່ວຍປັບປຸງຄວາມເຂັ້ມແຂງຂອງ adhesion.
4. Low shortening. The reaction between the epoxy resin and the curing agent used is carried out by direct addition reaction or ring-opening polymerization reaction of epoxy groups in the resin molecule, and no water or other volatile by-products are released. Compared with unsaturated polyester resins and phenolic resins, they show very low shortening (less than 2%) during the curing process.
- Mechanical function. The cured epoxy resin system has excellent mechanical functions.
