Composition：

ມັນເປັນໂປລີເມຍທີ່ມີຫຼາຍກຸ່ມຫນ້າທີ່.

ໂຄງສ້າງດັ່ງຕໍ່ໄປນີ້:

ພາກສ່ວນຂອງໂປລີເອສະເຕີ: ປະກອບມີກຸ່ມຫນ້າທີ່ຂອງທາດ carboxylic acid/ester;

ພາກສ່ວນອາມິໂນ: ບັນຈຸກຸ່ມທີ່ປັບປຸງເກືອ quaternary ammonium

ກົນໄກຫຼັກ:

1. ລະບົບການກະຈັດກະຈາຍຫຼາຍລະດັບ: ຊັ້ນກີດຂວາງຕົ້ນຕໍຖືກສ້າງຂຶ້ນໂດຍການຫມູນວຽນຂອງໂສ້ polyester.
2. ຜົນກະທົບຂອງການສະຫມໍ stereo: ກຸ່ມຫນ້າທີ່ອາມິໂນສ້າງສາຍສໍາພັນປະສານກັບສະຖານທີ່ບົກພ່ອງຜິວຫນ້າຂອງວັດຖຸກາກບອນ.
3. ການຮ່ວມມືຂອງຕົວລະລາຍ: ການສ້າງເຄືອຂ່າຍການຜູກພັນໄຮໂດຣເຈນກັບ NMP ເພື່ອປັບປຸງປະສິດທິພາບການຖ່າຍທອດມະຫາສານ.

ຂະບວນການນໍາໃຊ້ທີ່ແນະນໍາ:

1. ຂະບວນການໂມ້ປຽກລະດັບນາໂນ

ຂະບວນການໄຫຼ: ວັດຖຸດິບກ່ອນການກະຈັດກະຈາຍ → emulsification shear ຄວາມໄວສູງ (12000rpm, 20min) → grinder (3000rpm, 4h, ຄວບຄຸມອຸນຫະພູມ 50°C) → ການກໍາຈັດສິ່ງເປິະເປື້ອນແບບ centrifugal (12000g, 20min) → ການແຫ້ງແບບສູບອາກາດ (60°C, -0.09MPa)

Recommended Levels：

(1)、ການເພີ່ມສານກະຈາຍທີ່ແນະນໍາ: 20~50% (ເມື່ອສົມທຽບກັບວັດຖຸກາກບອນ)

(2)、ອຸປະກອນການໂມ້: ຫມາກຕຸ້ມ zirconium oxide (Φ0.5mm, ບັນຊີ 80%)

*. The above data are empirical dosages, and the optimal dosage needs to be determined through a series of tests.
