Paipu PTFE wela kiʻekiʻe no nā mīkini paʻi 3D | BESTEFLON

ʻOiai ʻo nā mea hana ʻenekinia e koi ana i nā mahana hoʻomau kiʻekiʻe no nā mīkini paʻi 3D, kiʻekiʻe nā koi ʻāpana. No laila, hoʻohana ka mīkini paʻi 3DPaipu PTFEe like me ka ʻōmole hānai (ʻōmole hānai). Hoʻohana nui ʻia nā ʻōmole PTFE i ka ʻoihana paʻi 3D, ʻo ia hoʻi ma muli o kēia hana:

ʻAʻole pipili: He inert ka PTFE, aneane ʻaʻole i hoʻopaʻa ʻia nā mea āpau me ka paipu PTFE, a hōʻike pū nā kiʻiʻoniʻoni lahilahi loa i nā waiwai non-stick.

Ke kūpaʻa wela a me ke anu: He kūpaʻa wela a haʻahaʻa ka paipu PTFE. Hiki iā ia ke kū i ka mahana a hiki i ka 300 ℃ i ka manawa pōkole, a ʻo ke kiko heheʻe he 327 ℃. ʻAʻole ia e heheʻe ma 380 ℃. Ma keʻano laulā, hiki ke hoʻohana mau ʻia ma waena o 240 ℃ a me 260 ℃. He kūpaʻa wela kupaianaha kona. Hiki iā ia ke hana i ka mahana hau. ʻAʻohe embrittlement, kūpaʻa anu a hiki i 65 ℃.

3. Lubricity: He haʻahaʻa ka coefficient friction o ka paipu PTFE. Hoʻololi ke coefficient friction ke paheʻe ka ukana, akā aia wale nō ka waiwai ma waena o 0.04-0.15.

4. ʻAʻole hygroscopicity: ʻAʻole pipili ka ʻili o ka paipu PTFE i ka wai a me ka ʻaila, a ʻaʻole maʻalahi ke pipili i ka hopena i ka wā o ka hana hana. Inā he liʻiliʻi ka lepo, hiki ke wehe ʻia ma ka holoi wale ʻana. He manawa pōkole ka downtime, e mālama ana i nā hola hana a hoʻomaikaʻi i ka pono o ka hana.

5. Ke kūpaʻa ʻana i ka pala: ʻAʻole i pala ka paipu PTFE e nā kemika, a hiki ke kū i nā waikawa ikaika āpau (me ka aqua regia), nā alkalis ikaika, a me nā waikawa ikaika koe wale nō nā metala alkali i hoʻoheheʻe ʻia, nā media fluorinated, a me ka sodium hydroxide ma luna o 300 ° C. ʻO ke kuleana o nā oxidants, nā mea hoʻemi a me nā mea hoʻoheheʻe organik like ʻole hiki ke pale i nā ʻāpana mai kekahi ʻano pala kemika.

6. Ke kūpaʻa ʻana i ka wā: ʻaʻohe ʻelemakule, ʻoi aku ka maikaʻi o ke ola ʻole i loko o nā plastik.

7. ʻaʻohe ʻawahia: i loko o 300 ℃ i loko o kahi kaiapuni maʻamau, hiki ke hoʻohana ʻia no nā lako lapaʻau a me nā meaʻai i ka physiologically inert, non-toxic.

8. Hoʻokaʻawale: Maikaʻi loa ka dielectric constant a me ke kiʻekiʻe o ka hoʻokaʻawale ʻana.

9. He liʻiliʻi ke koina friction, a maikaʻi ke kahe ʻana o nā mea maka.

Ma muli o ka hana maikaʻi loa o ka hose PTFE, ʻaʻole kūpono wale no ka ʻoihana paʻi 3D, akā hoʻohana nui ʻia hoʻi i ka pipeline anticorrosion, ke kiʻekiʻe o ka mahana, ka haʻahaʻa o ka mahana a me ke kūpaʻa i ka corrosion. A hoʻohana ʻia i nā ʻano ʻino e like me ka lubrication, nā mea uila, nā mīkini uila, aerospace a me ka mālama lapaʻau.
