ʻO Chain extender kahi ʻano mea hiki ke hoʻonui i ke kaulahao mole a hoʻonui i ka

kaumaha molekala ma ka hana ana me ka hui hana ma ke kaulahao polimer laina.

Hoʻohana maʻamau no ka hoʻomaikaʻi ʻana i nā waiwai mechanical a me nā waiwai hana o

polyurethane, polyester, nylon a me nā huahana ʻē aʻe.

ʻO ka epoxy chain extender kahi mea hoʻonui kaulahao i loaʻa ka glycidyl methacrylate (GMA).

ʻO nā mea hoʻonui kaulahao epoxy i hoʻohana mau ʻia me ka styrene-glycidyl methacrylate, nona

ʻoi aku ka maikaʻi o ka wela a hiki ke loaʻa i ke kani kani me ka PA6, ʻaʻole

hui kino kino maemae.Hiki ke hoʻohana ʻia i ka ʻōpala PET recycling a me nā mea ʻē aʻe.ʻO ka

ʻO ka hana o nā kaulahao epoxy i loko o ka nylon i hoʻololi ʻia penei:

1. Ka hopena i ke kaumaha molekala a me ka viscosity intrinsic

Hiki i nā mea hoʻonui kaulahao epoxy ke hana me ka hui amino hope a me ka pūʻulu carboxyl hope o

PA6, a laila hoʻomaikaʻi i ke kaumaha molekala o PA6.Eia nō naʻe, hiki i ka gelation ke hana i ka wā

ka hopena o ke kaulahao, no laila pono e hoʻomalu i nā kūlana kūpono, ʻoi aku

ka mahana a me ka wikiwiki o ka wili, e pale i ka hoʻopili ʻana i ka extrusion reactive.

Ua piʻi wikiwiki ka viscosity intrinsic o PA6 me ka piʻi ʻana o ka nui o ke kaulahao

mea hoʻonui.Ke piʻi aʻe ka ʻike o ka mea hoʻonui kaulahao i kekahi hakina nui, ʻo ka

Ua emi iki ka viscosity intrinsic o PA6.No ka mea hiki i ka hui hope o PA6

e hana koke me ka hui epoxy i loko o ke kaulahao ma muli o ka polarity a me ka hydrogen

pili.Ke haʻahaʻa ka nui o ka mea hoʻonui kaulahao, ʻo ka hapa o ke kaulahao lōʻihi

piʻi nā molekala i loko o ka ʻōnaehana a piʻi ka viscosity e like me ia;

Eia naʻe, e like me kaHoʻomaka ka hopena, e emi ana ka ʻike o ka hui hope o PA6, a me ka hui ʻana

hiki ika hopena o ke kaulahao molekala ua hoemi loa ia ma muli o ka mana o

hoolaha welaa ʻo ka lōʻihi o ke kaulahao molekala, ʻo ia hoʻi, ka mea hoʻonui kaulahao nui loa

hiki ke alakaʻi i kahika liʻiliʻi o ka gel i loko o ka ʻōnaehana, e alakaʻi ana i ka emi ʻana o ka hoʻonui kaulahao

ponoa me ka viscosity intrinsic PA6.

2. Ka hopena i nā waiwai mechanical

Ua hoʻonui ʻia ka nui o ka molekala pili o PA6 ma hope o ka hoʻonui ʻia ʻana o ke kaulahao me ke kaulahao epoxy

extender, Hiki ke hoʻomaikaʻi maikaʻi ʻia ka paʻakikī o ka mea ma ka emi ʻana

crystallinity a me ka nui o ka palaoa. Eia kekahi, me ka hoʻonui o ka lōʻihi o ke kaulahao mole,

piʻi ka hoʻopaʻapaʻa ma waena o nā kaulahao, a paʻakikī ke paheʻe ke kaulahao molekala.In

ma kēia ala, hiki ke komo i ka ikehu hopena ma ka hoʻololi ʻana i ka hoʻonohonoho o ka molekala

kaulahao i ka wā i hoʻopilikia ʻia e ka honua o waho.Akā, i ka hapa nui o ke kaulahao extender

ʻoi aku ma mua o kekahi ʻāpana, hoʻemi ʻia nā waiwai mechanical āpau./n

3. Ka hopena i nā waiwai rheological

Ua emi nui ka melt flow rate (MFR) me ka piʻi ʻana o ka mea hoʻonui kaulahao epoxy,

e hōʻike ana ua loaʻa i ka mea hoʻonui kaulahao epoxy a me PA6 ka hopena hoʻonui kaulahao kūpono.

Me ka piʻi ʻana o ka nui o ka mea hoʻonui kaulahao, ua hoʻonui mua ʻia ka torque equilibrium

a laila emi iho, no ka mea, ke kaumaha molekalale pili o PA6 ma hope o ka hoʻonui kaulahao

hoʻonui ʻia, hoʻonui ʻia nā entanglements i loko o ke kaulahao molecular, a me ka viscosity hehee pū kekahi

hoʻonui ʻia, no laila ua hoʻonui ʻia ka torque equilibrium.

Me ka hala o ka manawa, ua palupalu ka PA6 pellet, ua hoʻopaʻa ʻia a hoʻoheheʻe mālie ʻia, ka

ua emi iho ke ku'eku'e o ka rotor, a ua emi pu ka torque.

Qingdao Sainuo Chemical Co., Ltd.He mea hana mākou noPE wax, PP wax,
