Mea hoʻolako honua no ka mālama ʻana i ke kaiapuni

Wehewehe kumu o ka Huahana

Low Carboxylic PʻoʻoleʻaCpūhakaʻike ʻia e ka haʻahaʻa haʻahaʻa carboxyl maʻiʻo a me ka hiki ke hoʻololi ikaika. Hāʻawi nui lākou i nā hiʻohiʻona o lalo me nā koi kumu no ka kūpaʻa waiwai a me ke kūpaʻa hydrolysis, e like me ka hana monofilament.

Nā hiʻohiʻona huahana kumu

1.Kāpena CarboxylicMaʻiʻo, Kākoʻo i nā koi i hoʻopilikino ʻia

ʻO ka maʻiʻo carboxyl hope o Low Carboxylicnā ʻāpana polyesterua hoomalu pono ia ma ≤12% mol/t. Hiki ke hāʻawi ʻia nā hoʻoponopono kikoʻī carboxyl e like me nā ʻenehana hana kikoʻī a me nā hiʻohiʻona noi o nā mea kūʻai mai lalo.

2.ʻOi aku ka maikaʻi o ka hoʻokumu ʻana i ke kinona a me ke kūpaʻa ʻana o ka mīkini

Low Carboxylicnā ʻāpana polyesterLoaʻa ka haʻahaʻa haʻahaʻa o ka carboxyl i loko o kā lākou mau kaulahao mole, a ʻoi aku ka maikaʻi o ke kaulahao mole, ʻoi aku ka maikaʻi o ka crystallinity, a ʻoi aku ka maikaʻi o ka linearity. Hāʻawi kēia i kekahi mau mea maikaʻi i nā waiwai mechanical e like me ke kūpaʻa.

3.Palekana Hydrolysis maikaʻi loa, kūpono no nā hiʻohiʻona humid

ʻO kekahi o nā hiʻohiʻona nui o ka hanaLow Carboxylicnā ʻāpana polyesterʻO ko lākou kūpaʻa hydrolysis:No ka mea he pūʻulu hydrophilic ka pūʻulu carboxyl terminal, ʻoi aku ka liʻiliʻi o kāna ʻike, ʻoi aku ka liʻiliʻi o ka hopena o ka hydrolysis a hoʻohaʻahaʻa i ka hana inā i loko o kahi wahi haʻahaʻa a i ʻole pili me ka wai.

4.Ka Hana Hana Paʻa, Hiki ke hoʻololi i nā kaʻina hana he nui

I ka hana ana,Low Carboxylicnā ʻāpana polyester hōʻike i ʻelua mau pōmaikaʻi nui:maikaʻi ka paʻa wela, hiki ke mālama i ka hana paʻa ma lalo o kekahi mau kūlana kiʻekiʻe - ʻoi aku ka liʻiliʻi o ka hopena i ka maikaʻi o ka hana ʻana ma muli o nā pilikia e like me ka decomposition thermal. ʻOi aku ka maikaʻi o kona spinnability, e hiki ai i ka hana maʻalahi e like me ka wili.

5.ʻO nā hiʻohiʻona noiʻi ākea, e kālele ana i nā kahua koi kiʻekiʻe

Me he mea wili maka,Low Carboxylicnā ʻāpana polyesterhiki ke hoʻohana ʻia e hana i nā lole lole me kekahi pale holoi a me ke kū'ē deformation, e hālāwai ana i nā pono kumu o nā lole waena a kiʻekiʻe a me nā lole lole home. 

I nā hiʻohiʻona plastik haʻahaʻa haʻahaʻa me nā koi kiʻekiʻe no ke kūpaʻa waiwai (e laʻa, nā pahu mea hana hale liʻiliʻi, nā ʻāpana mīkini maʻalahi),Low Carboxylicnā ʻāpana polyesterhiki ke hōʻoia i ka hilinaʻi lōʻihi o ka hoʻohana ʻana i nā ʻāpana ma o kā lākou mau waiwai mechanical maikaʻi loa
