ʻAʻole pono e mālama ʻia ka ʻelemakule o Teflon hose

ʻO nā paipu Teflon he mau paipu fluoroplastic i hana ʻia mai nā mea polytetrafluoroethylene ma ka hui ʻana, hana embryo, kaomi anu, sintering a me ka hoʻoluʻu.

He mau waiwai maikaʻi ko Teflon tubes:

①Haʻahaʻa friction coefficient;

②Ka pale ʻino: ikaika ka waika a me ka alkali, a aneane pau ʻole nā ​​​​mea kemika (ma ke kiʻekiʻe o ka fluorine a me ka hopena metala alkali), hiki ke pale aku i ka "Aqua regia" corrosion;

③Hoʻomaʻemaʻe iā ia iho: paʻakikī ka polytetrafluoroethylene e pili;

④ʻAʻole hiki ke wela;

⑤High wela kū'ē: PTFE teflon mea wela hiki ke hiki i -70 ° C ~ 260 ° C;

⑥High Resistance: Teflon tube me ke kūpaʻa kiʻekiʻe, ka hana insulation maikaʻi loa;

⑦Anti-aging: He maikaʻi loa ka hana anti-aging ʻo Teflon Tube, lōʻihi ke ola lawelawe.

ʻAʻole hiki ke nānā ʻole ʻia ka ʻelemakule o ka hose PTFE, e hoʻemi ʻia ka hana o nā huahana ma hope o ka ʻelemakule, no laila, ʻo ka hana ʻana o ka hopena, pono mākou e hoʻokō i nā ʻano hana e pale ai.

Hoʻopili ʻia ka lipine adhesive o nā huahana Teflon tube me ka sulfur curing system. Hiki ke hoʻomaikaʻi ʻia ka pale wela o kāna vulcanizate ma ka hōʻemi ʻana a i ʻole ka pale ʻana i ka hoʻohana ʻana i ka sulfur elemental, hiki ke hōʻemi a hoʻopau paha i ka polysulfide cross-linking a hana nui i ka sulfur a i ʻole disulfide cross-linking.

Pono ka hoʻohana ʻana i ka peroxide i mea e hoʻokō ai i ke kūpaʻa wela maikaʻi, no ka mea, ʻo ka hoʻōla ʻana me ka peroxide e hoʻopuka i nā crosslink carbon-carbon i ʻoi aku ka thermostable. Pono e uku nui ʻia i nā mea hoʻohui ʻē aʻe i ka wā e hoʻohana ai i ka peroxide. No ka laʻana, pono e ʻoi aku ka paʻakikī o ke koho ʻana i nā antioxidants, ʻoiai he nui o lākou e hoʻopilikia i ka peroxide, vulcanization.

Eia kekahi, i ka wā e hoʻohana ai i ka peroxide, e hoʻemi i ka nui o nā mea hoʻopiha wai e pale aku i nā cations peroxide mai ka decomposing, e hopena i ka vulcanization haʻahaʻa o ka hose kaomi kiʻekiʻe (ma ke ʻano o ka paʻakikī haʻahaʻa, modulus haʻahaʻa a me ka hoʻonohonoho hoʻokūkū kiʻekiʻe) . ʻO ka hoʻohui ʻana i nā pūhui maʻamau, e like me ka zinc oxide a i ʻole ka magnesium oxide, inā hiki, hiki ke hoʻomaikaʻi pinepine i ka pono o ka crosslinking o ka peroxide. ʻOi aku ka maikaʻi o ka ʻaila paraffin, makemake ʻoe e pale i ka hoʻohana ʻana i ka aila hydrocarbon aromatic a me ka solvent.
