Nūhou - Hoʻopau i ka ʻili ʻana o ka TPU ma ka Nylon Overmolding me Si-TPV, kahi mea hōʻoluʻolu ʻili palupalu kūpono no ka Nylon Overmolding

Hoʻopau i ka hoʻonā overmolding Nylon Si-TPV 3525-65A paʻakikī

No ke aha he mea nui ka Soft Overmolding ma ke Nylon?

ʻO Nylon, ma ke ʻano he plastic ʻenekinia, hoʻohana nui ʻia i nā ʻano hana like ʻole ma muli o kona mau waiwai mechanical maikaʻi loa. Eia nō naʻe, ʻo kona ʻili paʻa e alakaʻi pinepine ai i kahi ʻike paʻi maikaʻi ʻole a me ka hiki ke ʻānai ʻia ka ʻili i ka wā o ka launa pū ʻana me ke kanaka. No ka hoʻoponopono ʻana i kēia, ua hoʻopili ʻia nā elastomers palupalu me ka paʻakikī Shore mai 40A a 80A (maʻamau 60A ~ 70A) ma luna o nā substrates nylon, e hāʻawi ana i ka pale ʻili, hoʻonui i ka hōʻoluʻolu paʻi, a me ka maʻalahi o ka hoʻolālā.

ʻO nā ʻano hoʻopaʻa kino kuʻuna (e laʻa me nā hoʻolālā snap-fit, knurling, a i ʻole nā ʻili wili) no ka nylon overmolding e ʻeha nei i ka ikaika hoʻopili kūlike ʻole a me ke kūʻokoʻa hoʻolālā palena. I ka hoʻohālikelike ʻana, hoʻohana ka hoʻopaʻa kemika i ka pilina molekala, polarity, a i ʻole ka hoʻopaʻa hydrogen ma waena o nā mea, e hōʻoiaʻiʻo ana i ka hoʻopili like ʻana ma waena o ka interface a hiki i nā geometries paʻakikī.

ʻO nā hemahema o ka hoʻohana ʻana iā TPU no ka Nylon Overmolding

Hoʻohana nui ʻia ka Thermoplastic Polyurethane (TPU) no ka overmolding ma luna o ka nylon ma muli o kona kūpaʻa ʻana i ka ʻaʻahu a me ke kaulike mechanical maikaʻi. Manaʻo pinepine ʻia he kūpono ia me ka nylon ma muli o ko lākou polarity like. Eia nō naʻe, ʻeha pinepine ka TPU i ka hoʻopili maikaʻi ʻole ʻana o ka interfacial, e alakaʻi ana i ka peeling a i ʻole delamination, ʻoi aku hoʻi i nā hiʻohiʻona hoʻohana kiʻekiʻe a lōʻihi paha.—i ka hopena, e hōʻemi ana i ka maikaʻi a me ka hana o ka huahana.

Hoʻonā:Ke hoʻolauna nei iā Si-TPV 3525-65A, ʻo TPU koho ʻē aʻe, ka elastomer maikaʻi loa no ka overmolding nylon

No ka hoʻoponopono ʻana i nā palena o TPU, ua hoʻomohala ʻo Silike iā Si-TPV 3525-65A—he elastomer vulcanizate silicone-thermoplastic e mālama ana i nā waiwai i makemake ʻia o TPU me ka hoʻomaikaʻi nui ʻana i ka hoʻopili ʻana i nā substrates nylon.

ʻO kēiamea elastomer thermoplastic Si-TPV overmolding palupalu hounā hāʻawi:

1. Hoʻopili kemika maikaʻi loa me PA6, PA12, a me PA66

2. ʻO ka pilina overmolding paʻa a like

3. ʻIli palupalu me ka ʻoluʻolu o ka mea hoʻohana

4. ʻO ke kūpaʻa mechanical maikaʻi loa, ka wai, ke kūpaʻa aila, a me ke anuanu

Hana Hoʻonui Kiʻekiʻe o Si-TPV 3525-65A ma nā Nylon Substrates, He Haʻawina Hoʻohālikelike me TPU no ka Hoʻonui ʻana i ka Pili a me ka ʻOluʻolu Tactile!

Ke hoʻāʻo ʻana i ka hoʻopili ʻana: Loiloi Overmolding maʻamau

No ka hoʻohālikelike ʻana i ka hana hoʻopili, ua hoʻāʻo ʻia ʻo Si-TPV lāua ʻo TPU me ka hoʻohana ʻana i kahi kaʻina hana overmolding maʻamau:

Ua hoʻoheheʻe ʻia nā substrates Nylon (PA6), a laila ʻoki ʻia ma ke ʻano diagonal ma 45° a hoʻowali ʻia me ka pepa one 120-grit.

Ua hoʻokomo hou ʻia nā substrates i mālama ʻia i loko o nā ʻōmole no ka overmolding ma lalo o ka mahana a me ke kaomi i kāohi ʻia.

Ua hana ʻia nā hoʻokolohua tensile e loiloi i ka ikaika o ka hoʻopili ʻana o ka interfacial.

TPU vs. Si-TPV 3525- 65A ma PA6: Nā hopena hoʻāʻo Tensile Force ma ka haki a me ka hoʻopili ʻana

Hoʻomaikaʻi i ka hoʻolālā huahana Nylon me ka Soft-Touch Overmolding me nā hoʻonā Si-TPV 3525-65A

Ka Hoʻopili Kiʻekiʻe Loa iā PA6, PA12, a me PA66, Si-TPV 3525-65A Hoʻākāka ʻia ka Hana Hoʻopili

Ka Hoʻopili ʻana o TPU ma nā Papahana PA:

I ka piʻi ʻana o ka paʻakikī o TPU (60A a i 90A), ua emi nui ka ikaika o ka hoʻopaʻa ʻana iā PA6. Ma 90A, ʻaʻole i hoʻopaʻa piha ʻo TPU.

ʻO Si-TPV 3525-65A Overmolding, TPU koho no ka nylon overmolding:

Ua hōʻike ʻia ka pilina ikaika a kūlike me PA6. Ua hōʻike ka loiloi cross-sectional i ka hemahema o ka hui pū ʻana—ua noho paʻa ʻo Si-TPV i nā ʻaoʻao ʻelua o ka interface, e hōʻike ana i ka pilina kemika ikaika. I ka hoʻohālikelike ʻana, ua hōʻike nā interfaces TPU i ke koena liʻiliʻi, e hōʻike ana i ka hoʻopili nāwaliwali.

Mea pā palupalu Si-TPV 3525-65A ma nā ʻano Nylon āpau: Hilinaʻi ma PA6, PA12, PA66

Ua hoʻokō pū ka Modified Silicone Elastomer 3525-65A i ka hoʻopili paʻa ma nā ʻano nylon like ʻole.

ʻO ka Non-Sticky Thermoplastic Elastomer Si-TPV 3525-65A ma PA12, ʻaʻole i ʻike ʻia ka hoʻokaʻawale ʻana i ka wā o ka hoʻāʻo ʻana, e hōʻoia ana i ka pilina cohesive maoli me ka ʻole o ka hāʻule ʻana o ka interface.

Nā Elastomers ʻAʻohe Plasticizer Si-TPV3525- 65A ma PA66, ua mālama ka mea i ka pipili ikaika a me ke kūpaʻa o ke kūkulu ʻana ma lalo o ke kaumaha.

(Nānā: Hoʻohālikelike nā waiwai paʻakikī a pau o Shore a me nā kaʻina hana hoʻāʻo me nā kūlana hoʻāʻo elastomer a me ka hoʻopili honua.)

Aloha i ka ʻili ʻana o ka TPU - Hoʻonui i ka Si-TPV ʻoluʻolu a palupalu no ka Nylon Overmolding paʻa

Hoʻohui ʻo Si-TPV 3525-65A i ke kūpaʻa mechanical o TPU me ka pā palupalu a me ka hoʻopili kemika o ka silicone. Hāʻawi ia i kahi hopena overmolding holomua no nā ʻāpana nylon i hoʻohana ʻia i nā mea uila mea kūʻai aku, nā loko o nā kaʻa, a me nā mea hana ʻoihana.

Ma ka hoʻololi ʻana iā Si-TPV, hiki i nā mea hana ke hoʻopau i nā pilikia peeling TPU, hoʻolōʻihi i ke ola o ka huahana, hāʻawi i ka palekana, aesthetics, a me ka hana ergonomic kiʻekiʻe.
