ʻO ke kaʻina hana o ka PTFE ka nui o nā ʻanuʻu nui 4:
1. monomer synthesis
PTFEhe polymerization o ka tetrafluoroethylene (TFE) monomer polymerization o nā pūhui polymer.ʻO ka monomer synthesis o TFE ka hana mua i ka hana hana o PTFE.I kēia manawa, hoʻohana nui ka ʻoihana i ke ʻano electrolytic fluorination e hoʻomākaukau ai i ka monomer TFE, ʻo ia hoʻi, anhydrous hydrogen fluoride a me ka ethylene ma lalo o kekahi mau kūlana no ka hopena electrolysis e hoʻohua i ka monomer TFE.
2.Polymerization pane
TFE monomer i kekahi mahana a me ka puʻe, hoʻohui i ka catalyst a me ka solvent, ka hopena polymerization.I ka wā o ka hopena polymerization, hoʻomau ʻia ka monomer TFE e hana i ke kaumaha molekala kiʻekiʻe PTFE, ka mahana, ke kaomi, ke ʻano catalyst a me ka neʻe ʻana o ka hopena polymerization a me nā mea ʻē aʻe e hoʻopili i ke kaumaha molekala, ka hale a me nā waiwai o PTFE.
3.Mahope o ka lapaau
Ma hope o ka pau ʻana o ka hopena polymerization, pono ka mālama ʻana ma hope o ka loaʻa ʻana o nā huahana PTFE maʻemaʻe.Ma hope o ka mālama ʻana, ʻo ka holoi ʻana, ka hoʻomaloʻo ʻana, ka ʻoki ʻana, ka sieving a me nā hana ʻē aʻe e wehe i nā catalysts, nā mea hoʻoheheʻe a me nā mea haumia ʻē aʻe e loaʻa ai nā ʻāpana resin PTFE maʻemaʻe.
4. Molding kaʻina
Hoʻopili ʻia nā ʻāpana resin PTFE ma lalo o kekahi mau kūlana e loaʻa ai ka mea e pono aiPNā huahana TFE.ʻO nā ʻano hana hoʻoheheʻe e komo i ka extrusion, injection molding, calendering a pēlā aku, e like me nā koi like ʻole o nā huahana e koho i ke ʻano hana hoʻoheheʻe kūpono.ʻO ka mahana o ke kaʻina hana, ke kaomi, ka wikiwiki o ka hana a me nā mea ʻē aʻe e pili i ka hana a me ka maikaʻi o nā huahana PTFE.
Mea maka o PTFE
Ua ʻike ʻia ka resin Polytetrafluoroethylene (PTFE) e nā ʻepekema ʻAmelika i loko o ka hale hana i ka makahiki 1936, a i kēia manawa hiki i ka honua ke hana i ka PTFE ma lalo o 20 mau ʻāina, ʻo ka hapa nui o ia mau ʻāina kūkulu.ʻO Kina i ka 60s e haku i ka ʻenehana hana a ʻike i ka hana ʻana, ua lilo i mea kūʻai nui o PTFE, kahi i ʻoi aku ka nui o nā huahana haʻahaʻa ma mua o ka noi, akā nui nā huahana kiʻekiʻe e pono e hilinaʻi i nā mea lawe mai nā ʻāina kūkulu. .
ʻO nā huahana PTFE o Kina i kēia manawa ke lawe nui ʻia mai ʻAmelika Hui Pū ʻIa, Iapana, a me nā ʻāina ʻEulopa.Ma muli o ke kumukūʻai o ka halihali a me ka pōʻai hoʻolako, lawe mai ʻo Kina i ka mea maʻamau o Iapana, a me ka lawe ʻana mai o Iapana i nā huahana PTFE o ka maikaʻi maikaʻi e hoʻokō ai i ka noi home no ka kiʻekiʻe.
Wahi a ka hopena o ka mea kūʻai aku, ʻoi aku ka maikaʻi o nā huahana i ka ikaika mechanical o ka hoʻohana maoli ʻana i nā kūlana hana, ke kūpaʻa ʻana a me ke kūpaʻa wela kiʻekiʻe a me ka haʻahaʻa, ʻoi aku ka maikaʻi o nā mea i lawe ʻia ma mua o nā mea hale.
ʻO ke kūʻai ʻana i ka paipu PTFE kūpono ʻaʻole wale e pili ana i ke koho ʻana i nā kikoʻī like ʻole no nā noi like ʻole.ʻOi aku e koho i kahi mea hana hilinaʻi.ʻO Besteflon Fluorine plastic Industry Co., Ltd. kūikawā i ka hana ʻana i nā paipu PTFE kiʻekiʻe a me nā paipu no 20 mau makahiki.Inā he nīnau a he pono, e ʻoluʻolu e nīnau mai iā mākou no ka ʻōlelo aʻo ʻoihana.
