ʻO ke kiʻi ʻoniʻoni PTFE he ʻano hou o ka c-grade insulation material me ka maikaʻi o ka hana piha, i kūpono no nā koi kūikawā, e like me nā mea uila i hōʻailona ʻia e ke kala a i ʻole ka insulation uea, a me nā mea ʻē aʻe. ʻoihana a me ka ʻepekema uila a me ka ʻenehana.
PTFE kala kiʻiʻoniʻonihe ʻano hou ia o ka c-grade insulation material me ka maikaʻi loa o ka hana, i kūpono i nā koi kūikawā, e like me nā mea uila i hōʻailona ʻia e ke kala a i ʻole ka insulation uea, a me nā mea ʻē aʻe. -ka ʻepekema uila a me ka ʻenehana.I ka noi mua o ka PTFE plastik insulated uea a me ka uwea, ua kaupalena wale ia i ka uea kūloko a me ke alakai uea o ka uila a me ka uila i loko o ka kiʻekiʻe-mehana wahi o ka mokulele, moku a me nā lumi engine 'ē aʻe ma ke kahua kaua.Me ka hoʻolaha ʻana o ka ʻenehana hoʻomākaukau, ua hoʻonui ʻia ʻo PTFE i nā laina hoʻonohonoho uila a me nā lako uila i ka ʻāina wela kiʻekiʻe.I ka wā ma mua, ʻo nā kiʻi ʻoniʻoni PTFE kūloko ka nui o nā kala kūlohelohe o nā mea (no ka mea, ʻaʻole maʻalahi nā kiʻi ʻoniʻoni PTFE).I mea e hoʻokaʻawale ai i nā laina komo a i waho o nā hōʻailona hoʻoili like ʻole a maʻalahi lākou e ʻike ʻia, pono e hoʻohana ʻia ke ʻano o ka uhi ʻana no ke kala.
Me ka hana kiʻiʻoniʻoni ʻoniʻoni PTFE kūloko a hiki i kahi kikoʻī, ma o ka hoʻomaikaʻi ʻana i ke kaʻina hana, ʻoi aku ka nui o nā kuhikuhi hana o nā huahana i ka pae o nā huahana like ʻole.Eia nō naʻe, i kēia manawa, ʻike ʻia nā hemahema o nā huahana kiʻi ʻoniʻoni PTFE kūloko i ka manaʻo kala a me nā ʻano ʻē aʻe o ka helehelena, e like me ka puʻunaue like ʻole o nā kiko kala a me nā pilikia ʻē aʻe.Me ka hoʻomohala ʻana o ka ʻenehana hoʻomākaukau kiʻi ʻoniʻoni PTFE hou a me ka hoʻomaikaʻi mau ʻana o nā mea hoʻohana i ke ahi retardant koi no nā uea a me nā kaula, ua hoʻohana ʻia nā kiʻi ʻoniʻoni ʻoniʻoni PTFE insulated uea a me nā kaula i nā hale kiʻekiʻe, nā kaʻa kaʻa, kamepiula. pūnaewele wahi kūloko, subway a me nā kaiapuni wela ʻole.
Kaʻina hana o ka polytetrafluoroethylene kala kiʻiʻoniʻoni:
(1) pretreatment o ka PTFE resin maka mea
Hoʻokomo ʻia ka PTFE resin maikaʻi i loko o ka hale kōmaena mau ma 20 ℃ ~ 23 ℃ no 24 mau hola no ka mālama mua ʻana.
(2) hoʻomaʻamaʻa mua i nā puaʻa
E kau i ka puaʻa inorganic i loko o ka pā maloʻo o 2O ℃ ~ 23 ℃ no nā hola he 24 e hoʻohana ai.
(3) kala
Ua hoʻohui ʻia kekahi nui o ka PTFE i hoʻopaneʻe ʻia i ka resin maikaʻi i ka rammer, a ua hoʻohui ʻia kekahi nui o ka puaʻa inorganic i hoʻomaʻamaʻa mua ʻia e hui me ka wikiwiki nui e hoʻopuehu i ka puaʻa like, a ua wehe ka resin e hoʻomaʻamaʻa i ke kaʻina hana. .
(4) mole
Ua hoʻohui ʻia nā mea maikaʻi ʻo PTFE i hoʻoluʻu ʻia i loko o ka mold ma ke kaʻina hana anu, a ua kaomi ʻia ka resin 40 000g PTFE waihoʻoluʻu maikaʻi i loko o ka blank ma ka 100 ton mīkini kaomi ma ka 2O MPa hoʻoheheʻe hoʻokahi kaomi.I ka wā o ke kaomi ʻana, ua nānā ʻia i ke kinoea hoʻopau i mea e pale ai i ka māwae o ka mea hakahaka.
(5) sintering
E hoʻopau i ka embryo kala maikaʻi o ka umu sintering kiʻekiʻe, hoʻomehana ma kahi o 5 ℃ / ho i 330 ℃, mālama i ka wela, 3 mau hola, a laila piʻi ma kahi o 25 ℃ / h i kahi 380 ℃, insulation 10 ~ 14 mau hola, a laila hoʻoluʻu ma kahi o 20 ~ 25 ℃ / h a i 320 ℃, ka mālama ʻana i ka wela 3 ~ 4 h, ka hoʻoilo hope loa ma kahi o 5 ℃ o / h a hiki i 15 ℃, o pani uila maoli. hoʻolili i ka lumi wela, waho o nā huahana kala.
(6) lilo i kiʻiʻoniʻoni
Hoʻololi ʻia nā preforms sintered o nā huahana kala i nā preforms kiʻiʻoniʻoni lahilahi e ka lathe kūikawā.ʻO 0.1 mm × 100 mm × ʻoi aku ka nui o ka membrane blank ma mua o 300 m (mānoanoa × laula × lōʻihi).
(7) hoʻonohonoho kalena
ʻO ka waihoʻoluʻu ʻaoʻao blank ma hope o ka huli ʻana e hana ʻia e ka papa kuhikuhi kuhikuhi o ka ʻōwili wela (e nānā i ka FIG. 3) a lilo i degere kuhikuhi o 1.5 ~ 1.8, mānoanoa 0.05 mm semi-directional kiʻiʻoniʻoni, ʻōwili wela wela mana ma kahi o 100 ℃.
(8) ʻokiʻoki
E hana mākou i ka mānoanoa 0.05 mm semi-directional kala kiʻiʻoniʻoni me ka mīkini ʻoki ʻoki kūikawā i ka 0.PTFE kala kiʻi me 05 mm × 90 mm × ʻoi aku ka nui ma mua o 10m (mānoanoa × ākea × lōʻihi).
(9) ka nānā ʻana i ka ʻeke
E hōʻike ʻia ke kiʻi ʻoniʻoni PTFE i hoʻoponopono ʻia no ka nānā ʻana i loko, a e mālama ʻia ka nānā ʻana a me ka nui o ke kiʻi i ka manawa like.E hoʻopili ʻia nā huahana kūpono i nā ʻeke kiʻiʻoniʻoni PVC me ka palapala hōʻoia i hoʻopili ʻia.
