Nā hana o nā mea mānoanoa i ka PTFE Emulsion - 4 mau kuleana nui

I ka hana ana o PTFE kiʻekiʻe-mahana lole , ka impregnation kaʻanuʻu hoʻohana i ka PTFE emulsion (aqueous dispersion). Akā ʻo ka emulsion PTFE maka wale nō ka paʻakikī e hana pono. Hoʻohui ʻia nā mea mānoanoa e hoʻololi i kāna ʻano rheological a me ke kūpaʻa.

No ke aha mai? He kiʻekiʻe kiʻekiʻe ka resin PTFE a makemake e noho. Me ka ʻole o ka mānoanoa, e hoʻokaʻawale ka emulsion, e komo hohonu loa i loko o ka lole, a i ʻole e hana i nā uhi like ʻole.

Ua hoʻomaikaʻi ʻo Aokai PTFE i ke koho mānoanoa ma waena o nā ʻano impregnation. Hoʻomaopopo kēia ʻatikala i nā hana koʻikoʻi ʻehā o nā mānoanoa ma PTFE emulsion.

Hoʻopaʻa hoʻomaha a me ka hoʻopaʻa ʻana

ʻO ka resin PTFE he kiʻekiʻe kiʻekiʻe (ma kahi o 2.2 g/cm³) a makemake e noho a paʻakikī loa i ka wai. Me ka hoʻopaʻa ʻole ʻana, hoʻokaʻawale ka emulsion i loko o kahi papa waiwai sediment a me kahi papa wai maʻemaʻe - hiki ʻole ke hoʻohana ʻia no ka uhi paʻa.

Pehea ka hana ʻana o nā mānoanoa: Hoʻonui nui nā mea mānoanoa i ka viscosity o ka māhele wai, e hana ana i kahi ʻōnaehana pūnaewele e kākoʻo ana i nā ʻāpana resin. ʻO kēia:

• Hoʻonui i ke ola o ka emulsion - hiki ke hoʻohana ʻia no nā mahina ma mua o nā lā

• Kāohi i ka hoʻokaʻawale ʻana i ka wā o ka lawe ʻana a me ka mālama ʻana

• Hoʻopau i ka hoʻoheheʻe ʻana - ka lepo paʻakikī ma lalo o nā ipu

Aokai PTFE memo: No nā emulsions i mālama ʻia ma luna o 30 mau lā, paipai mākou i ka homogenization hou ma mua o ka hoʻohana ʻana, ʻoiai me nā mea mānoanoa, no ka mea, hiki i ka mālama ʻana i ka wā lōʻihi ke hoʻomau i ka lohi.

ʻO ke ʻano hoʻoheheʻe ʻana no ka hana maʻalahi

Hāʻawi nā mea mānoanoa i ka emulsion me ke ʻano shear-thinning (pseudoplastic): viscosity kiʻekiʻe i ka hoʻomaha, viscosity haʻahaʻa ma lalo o ka hoʻonāukiuki..

Ka hopena maʻamau: I ka wā o ka uhi ʻana, kahe manuahi ka emulsion i loko o ka lole fiberglass ma lalo o ke ʻoki ʻana, a laila mānoanoa koke ma hope o ka uhi ʻana e mālama i ka mānoanoa mānoanoa like ʻole me ka ʻole o ka kulu.

Hoʻoponopono i ka hohonu komo a me ke kaumaha o ka uhi ʻana

Ke hoʻokomo ʻana i nā substrate porous e like me ka lole fiberglass, hoʻoponopono i ke ʻano a me ke ʻano o nā mea mānoanoa e hiki ai ke hoʻomalu pono i ka hohonu o ka emulsion..

Pehea e hoʻomalu ai nā mānoanoa i kēia: ʻO ka viscosity kiʻekiʻe e hoʻolōʻihi i ke komo ʻana, e waiho ana i ka resin ma ka ʻili. Hiki i ka viscosity haʻahaʻa ke komo hohonu i loko o ka pūpū fiberglass. Hoʻoholo kēia i ka hoʻouka resin hope loa a me ka manaʻo lima o nā huahana i pau.

Hoʻomaikaʻi i ke ʻano like ʻole o ke kiʻiʻoniʻoni a me ka hōʻoia ʻana i ka Sintering me ke koena ʻole

1. Hoʻohui like kiʻiʻoniʻoni i ka wā maloʻo

ʻO ka viscosity lawa mai nā mānoanoa:

• Kāohi i ka pohā ma muli o ka neʻe ʻana o ka makū i ka wā maloʻo

• Kāohi i ka mānoanoa o ka uhi ʻole ʻia (nā ʻaoʻao mānoanoa, waena lahilahi)

• Hoʻomaʻamaʻa i ka hoʻokumu ʻana i nā kiʻiʻoniʻoni mua palahalaha mau

• E ho'ēmi i ka 'coffee ring effect' kahi e neʻe ai ka emulsion i nā ʻaoʻao

2. Ke koi koʻikoʻi - koena-free sintering

Pono ka emulsion PTFE i ka sintering ma kahi o 380 ° C e hoʻohui i nā ʻāpana PTFE i kahi kiʻiʻoniʻoni mau. Hāʻawi kēia i kahi koi kūikawā no nā thickeners:

Pono nā mānoanoa i koho ʻia e hoʻopau loa me ka ʻole o ke koena lehu i kēia mahana.

Aokai PTFE hoʻohana cellulose-ma muli mānoanoa (e laʻa me methyl cellulose) e puhi loa i 380 ° C, waiho ole lehu. Manaʻo mākou e pale aku i nā mea mānoanoa i loaʻa nā paʻakai inorganic a i ʻole nā ​​​​mea hoʻoheheʻe metala e waiho ana i ke koena.

Hoʻoholo ʻo Aokai PTFE i nā mānoanoa e kaulike i nā hana ʻehā me ka hōʻoia ʻana i ka hoʻopau piha ʻana i ka wā sintering. No nā ʻano hana impregnation maʻamau, hiki iā mākou ke hoʻoponopono i ke ʻano o ka mānoanoa a me ke ʻano e hoʻohālikelike ai i kāu kaumaha uhi kikoʻī a me nā koi komo lole.

Inā makemake ʻoe i nā kikoʻī kikoʻī, nā hihia noi a me nā hoʻoponopono i hoʻoponopono ʻia no kā mākou huahana piha e pili ana i nā lole wela kiʻekiʻe PTFE, PTFE adhesive tapes, PTFE mesh belts, seamless fusing machine belts, one-sided PTFE coated belts, heat-resistant conveyor belts a me nā lole fiberglass wela kiʻekiʻe, e ʻoluʻolu e kelepona mai iā mākou ma nā kahawai ma lalo:
