Nā hiʻohiʻona: ʻO ka mechanics, nā waiwai uila a me ka paʻa kemika, ua like ia me ka F4, akā ʻo ka pōmaikaʻi koʻikoʻi ʻo ia ke kiʻekiʻe o ka paʻakikī o ka hopena, ʻoiai ke holo wikiwiki ʻia ka hāpana notched, maikaʻi loa ke kū ʻana o ka wā a me ka radiation. a he maʻalahi hoʻi e hana a hana.He resin i loko o ka fluorine i hoʻomohala ʻia e lanakila ai i ka paʻakikī o ka hana ʻana i polytetrafluoroethylene.Ma waho aʻe o ka mahana hoʻohana ma lalo o F4, mālama ia i nā waiwai maikaʻi o polytetrafluoroethylene.

4. Polychlorotrifluoroethylene PCTFE (F3)

1. Mea kūpono: nā mea hoʻoheheʻe organik, nā wai etching inorganic (oxidizing acids).Hana wela: ≤120°C

2. Nā hiʻohiʻona: ʻo ke kūpaʻa wela, nā waiwai uila a me ke kūpaʻa kemika ʻelua wale nō i ka F4, ka ikaika mechanical, ke kūpaʻa kolo, ʻoi aku ka paʻakikī ma mua o F4.

5, polyvinylidene fluoride PVDF (F2)

1. Mea kūpono: kū'ē i ka nui o nā kemika a me nā mea hoʻoheheʻe.Hana wela: ≤120°C

2. Nā hiʻohiʻona: ʻoi aku ka maikaʻi o ka tensile a me ka ikaika compressive ma mua o F4, maikaʻi ke kūlou ʻana a me ke kahe anuanu;ka pale ʻana i ka wā, ka pale ʻana i ka radiation, ka pale māmā a me ka anti-aging, a me nā mea ʻē aʻe.

6, polypropylene i hoʻololi ʻia (GXPP)

1. Mea pili: he mea laha ole a i ole ia o ka wai o ka paakai inorganic, ka waika inorganic a i ole ka alkali.Hana wela: ≤100°C

2. Nā hiʻohiʻona: ʻO ia kekahi o nā plastics māmā loa.ʻOi aku ka maikaʻi o kāna hua, tensile a compressive ikaika a me ka paʻakikī ma mua o ka polyethylene haʻahaʻa haʻahaʻa.Loaʻa iā ia ka rigidity koʻikoʻi, ke kūpaʻa wela maikaʻi, ka hana maʻalahi a me ke kumu kūʻai haʻahaʻa.Ma hope o ka hoʻololi ʻana, hoʻomaikaʻi ʻia ka hopena, fluidity, a me ka modulus flexural o ka elasticity.

7. Hoʻololi ʻia ka polyolefin (GXPO)

1. Mea kūpono: nā ʻano ʻokoʻa o ka waikawa a me nā paʻakai alkali a me kekahi mau mea hoʻoheheʻe organik.Hana wela: ≤110°C

2. ʻO ia ka mea kiʻekiʻe kiʻekiʻe loa o ka honua no ka anti-corrosion, anti-static, non-toxic a me ka ikaika kiʻekiʻe.Ua hoʻohana nui ʻia i nā mea hoʻololi nui a me nā kiwi a me nā paipu no ka lining.Hoʻohana nui ʻia i ka kemika, metallurgical, meaʻai, halihali, lāʻau lapaʻau, textile a me nā ʻoihana ʻē aʻe.

8, polyvinyl chloride (paʻakikī) PVC

1. Mea pili: ka wai kūpaʻa, concentrated alkali, non-oxidizing acid, chain hydrocarbon, aila a me ka ozone.Hana wela: ≤60°C

2. Nā hiʻohiʻona: ʻoi aku ka maikaʻi o ka ikaika mechanical kiʻekiʻe, ke kūpaʻa kemika a me nā waiwai dielectric, ʻoi aku ka maikaʻi o ka pale ʻana i ka aila a me ke kūpaʻa kahiko, maʻalahi ke weld a hoʻopaʻa, ʻoi aku ka haʻahaʻa.

9. Ka polyethylene kaumaha mole kiʻekiʻe loa (UHMW-PE)

1. Mea kūpono: Hiki iā ia ke pale i nā ʻano media corrosive (koe wale ka waikawa, alkali, paʻakai, akā oxidizing acid) a me nā mea hoʻoheheʻe organik.Hana wela: ≤100°C

2. Nā hiʻohiʻona: kūʻokoʻa aahu, haʻahaʻa friction coefficient a me ka lubricating;ʻoi aku ka maikaʻi o ke koʻikoʻi o ke koʻikoʻi, ke kūpaʻa kiʻekiʻe kiʻekiʻe a me ke kūpaʻa haʻahaʻa haʻahaʻa;ikaika tensile maikaʻi loa, ikaika hopena kiʻekiʻe loa.Paʻa kemika maikaʻi loa a me ke kūpaʻa luhi;ʻaʻohe adsorption ma luna o ka ʻili, ka hoʻokaʻawale uila maikaʻi loa;ʻaʻohe hana piha e like me ka non-toxicity.

10, FRP (phenolic) FRP

1. Mea kūpono: ka mea hoʻoheheʻe organik, ka aila pale wela, ka waikawa a me ka brine.Hana wela: ≤120°C

2. Nā hiʻohiʻona: High mechanical properties, haʻahaʻa friction coefficient ma lalo o ka wai lubrication, maikaʻi nā waiwai uila a me ka haʻahaʻa kū'ē i ka waikawa a me ka alkali corrosion,ʻaʻole maʻalahi e hoʻololi i ka mahana a me ka haʻahaʻa, maʻalahi e hana a haʻahaʻa i ke kumukūʻai.
