The manufacture of PTFE BESTEFLON

ʻO ke kaʻina hana o ka PTFE e pili ana i nā ʻanuʻu nui 4:

1. hana ʻana o ka monomer

PTFEʻO ka polymerization o ka tetrafluoroethylene (TFE) monomer polymerization o nā hui polymer. ʻO ka synthesis monomer o TFE ka hana mua i ke kaʻina hana o PTFE. I kēia manawa, hoʻohana nui ka ʻoihana i ke ʻano fluorination electrolytic e hoʻomākaukau i ka monomer TFE, ʻo ia hoʻi, ka hydrogen fluoride anhydrous a me ka ethylene ma lalo o kekahi mau kūlana no ka hopena electrolysis e hana i ka monomer TFE.

2. Ka hopena polymerization

ʻO ka monomer TFE ma kahi mahana a me ke kaomi, e hoʻohui i ka catalyst a me ka solvent, ka hopena polymerization. I ka wā o ka hopena polymerization, ua hoʻomau ʻia ka polymerization TFE monomer e hana i ka PTFE kaumaha molekala kiʻekiʻe, ʻo ka mahana, ke kaomi, ke ʻano catalyst a me ka nui o ka hopena polymerization a me nā mea ʻē aʻe e hoʻopilikia i ke kaumaha molekala, ka hoʻonohonoho a me nā waiwai o PTFE.

3. Ma hope o ka mālama ʻana

Ma hope o ka pau ʻana o ka hopena polymerization, pono ka mālama ʻana ma hope e loaʻa ai nā huahana PTFE maʻemaʻe. ʻO ka mālama ʻana ma hope e pili ana i ka holoi ʻana, ka hoʻomaloʻo ʻana, ka kuʻi ʻana, ka sieving a me nā ʻanuʻu ʻē aʻe e wehe ai i nā catalysts, nā solvents a me nā haumia ʻē aʻe e loaʻa ai nā ʻāpana resin PTFE maʻemaʻe.

4. Kaʻina hana hoʻoheheʻe

Hoʻoheheʻe ʻia nā ʻāpana resin PTFE ma lalo o kekahi mau kūlana e loaʻa ai ka mea e pono aiPNā huahana TFEʻO nā ʻano hana hoʻoheheʻe ʻana e komo pū me ka extrusion, ka hoʻoheheʻe ʻana i ka injection, ka calendering a pēlā aku, e like me nā koi like ʻole o nā huahana e koho i ke ʻano hoʻoheheʻe kūpono. ʻO ka mahana o ke kaʻina hana hoʻoheheʻe, ke kaomi, ka wikiwiki o ka hana a me nā mea ʻē aʻe e hoʻopilikia i ka hana a me ka maikaʻi o nā huahana PTFE.

Mea maka o PTFE

Ua ʻike hewa ʻia ka resin Polytetrafluoroethylene (PTFE) e nā kānaka ʻepekema ʻAmelika ma ke keʻena hoʻokolohua 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 he mau ʻāina i hoʻomohala ʻia. I nā makahiki 60, ua lilo ʻo Kina i mea kūʻai nui o ka PTFE, kahi i ʻoi aku ai ka nui o nā huahana haʻahaʻa ma mua o ke koi ʻia, akā pono nō hoʻi nā huahana kiʻekiʻe e hilinaʻi i nā mea lawe mai mai nā ʻāina i hoʻomohala ʻia.

ʻO nā mea maka a me nā huahana PTFE o Kina i kēia manawa e lawe nui ʻia mai ana mai ʻAmelika Hui Pū ʻIa, Iapana, a me nā ʻāina ʻEulopa. Ma muli o ke kumukūʻai halihali a me ke kaʻina hana hoʻolako, ʻo Kina ke lawe mai i nā mea maʻamau o Iapana, a ʻo Iapana ke lawe mai i nā huahana PTFE o ke ʻano maikaʻi e hoʻokō i nā koi kūloko no ka mea kiʻekiʻe.

Wahi a ka manaʻo o ka mea kūʻai hope loa, ʻoi aku ka maikaʻi o nā huahana i ka ikaika mechanical o nā kūlana hana maoli, ke kūpaʻa kolo a me ke kūpaʻa o ka mahana kiʻekiʻe a me ka haʻahaʻa, ʻoi aku ka maikaʻi o nā mea i lawe ʻia mai ma mua o nā mea kūloko.

ʻO ke kūʻai ʻana i ka paipu PTFE kūpono ʻaʻole wale ia e pili ana i ke koho ʻana i nā kikoʻī like ʻole no nā noi like ʻole. ʻOi aku ka nui e koho ai i kahi mea hana hilinaʻi. He loea ʻo Besteflon Fluorine plastic Industry Co., Ltd. i ka hana ʻana i nā hose a me nā paipu PTFE kiʻekiʻe no 20 mau makahiki. Inā he mau nīnau a me nā pono, e ʻoluʻolu e nīnau mai iā mākou no ka ʻōlelo aʻoaʻo loea hou aku.
