ʻO ka lole kiʻekiʻe o ka PTFE - Single-Dip vs. Multi-Dip Impregnation Process

ka lole wela kiʻekiʻe o PTFE (PTFE-coated fiberglass) me ka hoʻohana ʻana i ʻelua ala kumu like ʻole: Hiki ke hana ʻia hoʻokahi-dip impregnation a me ka multi-dip impregnation . ʻO ka koho ma waena o lākou e hoʻoholo i ka mānoanoa o ka uhi, ka maikaʻi o ka ʻili, ka pae hana, a me ke kumukūʻai.

Ma ke kaʻina hana hoʻokahi, hele ka lole fiberglass i hoʻokahi pōʻai holoʻokoʻa impregnation-drying-sintering. Ma ke kaʻina hana multi-dip, e hoʻomau ʻia nā pōʻai - maʻamau 2-3 holo a ʻoi aku ma mua o hoʻokahi kakini - ke kūkulu ʻana i ka PTFE papa ma ka papa.

Hoʻohana ʻo Aokai PTFE i nā kaʻina ʻelua ma muli o ka noi. Hōʻike kēia alakaʻi i ka wehewehe, kaʻina hana, nā hiʻohiʻona, a me nā noi maʻamau o kēlā me kēia, me ka hoʻohālikelike hana ʻaoʻao.

Hoʻokahi-Dip Impregnation Kaʻina - wikiwiki a me ke kumu kūʻai

1. Ka wehewehe a me ke kaʻina hana

Wehewehe: Hele ka lole fiberglass i hoʻokahi pōʻai holoʻokoʻa o ka impregnation-drying-sintering e hana i ka lole i uhi ʻia i ka PTFE.

Kaʻina hana:
Fiberglass fabric → impregnation me ka PTFE dispersion → squeeze-off/doctor-blade coating e hoʻomalu i ka resin pickup → haʻahaʻa wela hoʻomaloʻo no ka hoʻoneʻe wai → kiʻekiʻe-mehana sintering (360-400 ° C) e hoʻoheheʻe i ka PTFE i loko o kahi kiʻi hoʻomau → hoʻomaloʻo a me ka wili-up.

2. Kaʻina hana

• Ua kaupalena ʻia ka ʻohi ʻana o Resin, e hāʻawi ana i lahilahi, haʻahaʻa-grammage ka lole

• ʻAʻole hiki ke hoʻopiha piha ʻia ke ʻano o ka fiberglass i ulana ʻia, e hopena i kahi ʻili ʻōpala me nā micro-pinholes

• ʻO ka uhi PTFE piha ʻole ke alakaʻi i ka ikaika haʻahaʻa haʻahaʻa, ka ikaika dielectric, ke kū ʻana o ke kinikini, a me ka hana non-stick.

• He ka pōʻaiapili hana pōkole me ka maikaʻi kiʻekiʻe a me kumu kūʻai haʻahaʻa nā pono

3. Nā noi maʻamau

Hoʻohana ʻia ka lole lole hoʻokahi no nā hiʻohiʻona me nā koi haʻahaʻa i ka mānoanoa, impermeability, a me ka maʻalahi o ka ʻili:

• Haʻahaʻa-papa insulating gaskets

• Moena lāʻau ʻole no ka manawa

• ʻO nā mea semi-permeable e paʻa i ka ʻāpana ea

• ʻO nā hoʻohana ʻoihana koʻikoʻi ʻole inā ʻo ke kumukūʻai ka mea hoʻokele mua

Ke Kaʻina Hana Impregnation Multi-Dip – Layer-by-Layer Performance Build-Up

1. Ka wehewehe a me ke kaʻina hana

Wehewehe: Ke hele nei ka substrate fiberglass i nā pōʻai pinepine o ka impregnation-drying-sintering, maʻamau mai ka 2-3 holo a ʻoi aku ma mua o hoʻokahi kakini. Hoʻokomo ʻia kēlā me kēia papa ma hope o ka uhi PTFE e kūkulu i ka mānoanoa, hoʻopiha i nā hakahaka, a hoʻoponopono i nā hemahema o ka ʻili.

Kaʻina hana:
Fiberglass fabric → 1st impregnation → maloʻo → sintering → cooling → 2nd impregnation → maloʻo → sintering → cooling → 3rd impregnation… Hope wili-up ke hoʻokō ʻia ka mānoanoa pahuhopu, grammage, a me nā kikoʻī hana.

Hoʻololi hoʻolālā:

• Nā pōʻai mua: Haʻahaʻa-viscosity, kiʻekiʻe-komo PTFE dispersion - komo piha i loko o nā pūpū fiber

• Nā ʻanuʻu hope: Hoʻopuehu kiʻekiʻe-viscosity a ʻoi aku ka paʻa-paʻa-maʻiʻo - kūkulu i nā kiʻiʻoniʻoni ma luna a hoʻopaʻa i nā puka pin

2. Kaʻina hana

• Hiki ke hoʻoponopono pololei ʻia ka mānoanoa a me ka hoʻouka ʻana o ka PTFE

• Hiki i ka helu PTFE ke hiki i ka 50-70% a i ʻole ke kiʻekiʻe

• Hoʻopiha hou ʻia ka impregnation a me ka sintering i nā āpau ma waena o nā filament fiber a hoʻopau i nā pinholes, e hāʻawi ana i kahi uhi ʻoluʻolu a paʻa.

3. Hana maikaʻi

• ʻOi aku ka maikaʻi non-stick a me ka hoʻokuʻu waiwai

• Kūʻē kūʻē kemika-corrosion a me ka impermeability

• Hoʻomaikaʻi nui ʻia ka ikaika dielectric a me ka resistivity volume

• ʻO ke kūpaʻa kūpaʻa paʻa me kahi mahana lawelawe lōʻihi a hiki i 260 ° C

Nā Kūʻai Kūʻai: Hoʻonui i ka manawa alakaʻi hana, ka hoʻohana ʻana i ka ikehu kiʻekiʻe, ka hoʻomalu ʻana i ke kaʻina hana, a ʻoi aku ka nui o nā kumukūʻai hana.

4. Nā noi maʻamau

Hāʻawi ka lole multi-dip i nā ʻoihana ʻoihana kiʻekiʻe kiʻekiʻe, kahi e hōʻoia ai ka hana i ke kumukūʻai:

Hoʻohālikelike Hana Nui - Ma kahi ʻaoʻao

Hōʻuluʻulu manaʻo - Ke koho ʻana i ke kaʻina hana kūpono no kāu noi

ʻO ka single-dip impregnation kahi ʻano uhi kiʻiʻoniʻoni wikiwiki e hōʻike ana i nā pōkole hana pōkole a me nā kumukūʻai haʻahaʻa, akā i kaupalena ʻia e ka hoʻopau ʻana i ka ʻili a me ka hana pale haʻahaʻa.

ʻO ka multi-dip impregnation kahi hoʻopili ʻana i kēlā me kēia ʻāpana a me ke ʻano hana kūkulu e hoʻopili piha ai i ka substrate fiberglass. Hāʻawi ia i ka lole i uhi ʻia i ka PTFE maʻemaʻe me ka hana ʻoi aku ka maikaʻi ma ka uku o nā kahe hana paʻakikī a me nā kumukūʻai kiʻekiʻe.

Hana ʻo Aokai PTFE i ka lole PTFE hoʻokahi a me ka nui. No ke koi ʻana i nā noi ʻoihana, kokoke i nā lole fiberglass PTFE-impregnated kiʻekiʻe e hana ʻia ma o ke kaʻina hana multi-dip. E hoʻokaʻaʻike mai iā mākou e kūkākūkā i ka papa e kūpono i kāu koi noi.
