Nailon Screw Material: Nonmetallic Synthetic Polymer
Hana ʻia nā ʻili nylon mai ka polyamide (PA), kahi mea polymer synthetic a me kahi nonmetal maʻamau. ʻO kona ʻano kemika he mau pūʻulu amide hou (-CONH-), he ʻokoʻa loa ia mai ke ʻano aniani o nā metala. Eia ka hoʻohālikelike o nā waiwai kī.
1. Conductivity: Loaʻa i ka Nylon ka resistivity a hiki i ka 10 ^ 12-10 ^ 15 Ω·cm (kumu ʻikepili: * Plastics Materials Handbook *), e hoʻolilo iā ia i insulative loa, ʻoiai he conductive nā wili metala.
2. Density: He 1.1-1.2 g/cm³ ka nui o ka nylon, he 1/7 wale nō ko ke kila (7.8 g/cm³), e hāʻawi ana i nā pono māmā.
3. Heʻe Heʻe: ʻO 180-260 degere ka hoʻoheheʻe ʻana o Nylon (ma muli o ke kumu hoʻohālike kikoʻī), haʻahaʻa loa ma mua o ka helu heheʻe o nā wili metala, hiki ke ʻoi aku ma mua o 1,000 degere.
No ke aha e koho ai i nā screws nylon? Pōmaikaʻi o ʻElima ʻAʻole -Metalika
1. ʻAi ʻino: ʻAʻole kūʻē ʻo Nylon i nā waikawa, alkalis, a me ka paʻakai paʻakai, kūpono ia i nā kaiapuni kemika a me ke kai, a me ka pale ʻana i ka ʻōpala metala.
2. Hoʻopili palekana: Hoʻohana ʻia i nā lako uila (e like me ke kau ʻana o ka papa kaapuni) e pale i nā pōkole pōkole.
3. Hoʻoemi ʻia ka haʻalulu a me ke kani: ʻO kahi modulus elastic haʻahaʻa (2-4 GPa) e hoʻopaʻa i ka haʻalulu a hoʻemi i ka walaʻau mechanical.
4. ʻAʻole -Magnetic: He kūpono no nā polokalamu pili i nā mākia, e like me nā lako MRI.
5. Ka Mana Kūʻai: He ʻoi aku ka maikaʻi o ka hoʻoheheʻe ʻia ʻana o ka leo kiʻekiʻe, a ʻoi aku ka maikaʻi o 30%-50% ma mua o nā wili kila kila (e nānā i ka ʻikepili mai nā kahua kūʻai ʻoihana).
Nā ʻano hoʻohana a me nā palena: ʻAʻole hana mau nā ʻūlū Metala ʻole
1. Manaʻo ʻia nā noi:
- Māmā-nā hale hoʻouka (e like me ke kau ʻana o ka hale ʻilika).
- Nā lako uila me nā koi hoʻokiʻekiʻe kiʻekiʻe.
- Nā wahi ʻino (e like me nā lako ʻauʻau a me nā mīkini hana meaʻai).
2. Nā noi kūpono ʻole:
- Nā kaiapuni wela kiʻekiʻe (hiki paha ke hoʻololi ʻia ma ka wela ma mua o 120 degere ).
- Kiʻekiʻe-ka hoʻopaʻa ʻana i ka torque (ma kahi o 80 MPa ka ikaika tensile o ka nylon, ʻo 1/10 wale nō ko ke kila kalapona).
Hōʻuluʻulu manaʻo: He laʻana maʻamau nā wili naylon o -mea metala ʻole, ua hoʻokō ko lākou mau waiwai i nā metala. Ke koho ʻana i ka wili nylon, e noʻonoʻo i ka ikaika, ka mahana, a me ka noʻonoʻo ʻana i ke kumukūʻai, ma mua o ka hoʻololi wale ʻana i nā wili metala.
