Otu esi anwale ogo PTFE Emulsion: 6 isi ihe ngosi & ụzọ

PTFE emulsion - makwaara dị ka PTFE dispersion - bụ akụrụngwa maka mkpuchi fiberglass ákwà na-emepụta. PTFE akwa okpomọkụ dị elu , teepu, na eriri. Ọ bụrụ na agbanyụrụ àgwà emulsion, ngwaahịa ikpeazụ ga-enwe arụmọrụ na-adịghị mma, mkpuchi na-enweghị isi, ma ọ bụ ọdịda akaghi aka.

Ma olee otu ị ga-esi mara ma ọ bụrụ na otu emulsion PTFE dị mma? Ị nwalee ya.

Aokai PTFE ejirila ma nwalee emulsions PTFE ruo ọtụtụ afọ. Ntuziaka a na-ekpuchi ihe ngosi nyocha isi isii - ọdịnaya siri ike, pH, nha nha, viscosity, nkwụsi ike, na ọdịdị - na usoro ọkọlọtọ na njirisi nnabata.

Ọdịnaya siri ike - Ngosipụta kachasị

Ọdịnaya siri ike na-emetụta arụmọrụ ngwaahịa ozugbo yana akụ na ụba ngwa (ihe mkpuchi siri ike chọrọ ihe siri ike dị elu).

Ụzọ nnwale ndị a na-ahụkarị:

Usoro nnabata:

• Kwa ọkọlọtọ T/FSI 067-2021: Ọdịnaya siri ike chọrọ maka itinye uche PTFE ugboro ugboro bụ 60± 2%

• Ọkọlọtọ njikwa saịtị n'ezie: 60± 0.5% (nnweta siri ike maka mkpuchi na-agbanwe agbanwe)

Uru pH – Ihe ngosi nkwụsi ike

Uru pH na-emetụta nkwụsi ike nchekwa, nrụrụ na ndakọrịta na ihe ndị ọzọ.

Usoro nnwale: Usoro Electrode Glass (Mkpebi ziri ezi) - tụọ ihe site na iji mita pH nwere electrode iko nke agbaziri site na nhazi nkeji abụọ ma ọ bụ atọ. Nke a bụ usoro ọkọlọtọ a na-ejikarị eme ihe.

Usoro nnabata:

• Kwa T/FSI 067-2021: pH nso 9.0 - 11.0

• Mgbanwe na pH na-egosikarị enweghị ntụkwasị obi sistemu ma ọ bụ mmeghachi omume kemịkalụ mere (dịka ọmụmaatụ, hydrolysis nke surfactant)

• Ogologo oge nsochi nke pH mgbanwe dị mkpa maka ikpe ikpe nkwụsi ike nke emulsion

Ihe kpatara pH ji dị mkpa: PTFE emulsions na-edozi site na fluorinated surfactants, nke chọrọ ọnọdụ alkaline (pH> 8) iji nọgide na-arụ ọrụ. Ọ bụrụ na pH dara n'okpuru 8, emulsion nwere ike ịgbakọta.

Aokai PTFE na-akwado ịnwale pH na drum ọ bụla na-abata na kwa ọnwa n'oge nchekwa. Mbelata na mberede site na 10.2 ruo 8.5 n'ime izu abụọ na-egosi emulsion na-emebi emebi na ekwesịrị iji ya ozugbo ma ọ bụ jụ.

Oke urughuru & Nkesa nha nha

The size na nkesa uniformity nke PTFE isi irighiri nwere a bụrụkwa mmetụta na film-akpụ Njirimara, permeability, na ikpeazụ ngwaahịa arụmọrụ.

Ụzọ nnwale:

Ihe ngosi nlere anya:

• D50 (dayameta etiti) - ụdị ụdị maka emulsion PTFE: 0.1-0.3 microns

• Ughuru nha nkesa obosara - narrower ka mma maka agbanwe agbanwe mkpuchi

• D10 na D90 - mara mgbasa nke nkesa

Ntuziaka nnabata: Maka ọtụtụ ngwa mkpuchi, D50 kwesịrị ịdị n'etiti 0.15 na 0.25 μm na 90% nke ihe dị n'ime ± 0.1 μm nke pụtara.

Viscosity – Nhazi ngwa ngwa

Viscosity na-egosipụta omume na-asọpụta, na-emetụta mkpuchi na usoro impregnation ozugbo.

Ụzọ nhakarị:

Usoro nnabata:

• Kwa T/FSI 067-2021: Oke viscosity 12.0 – 30.0 mPa·s (na 25±1°C)

• Viscosity nke dị oke ala → mkpuchi na-enweghị isi, na-agbapụta

• Viscosity nke dị elu → adịghị mma ịbanye n'ime fiberglass, chọrọ dilution

Mara bara uru: Maka itinye mkpuchi nke akwa fiberglass, viscosity lekwasịrị anya bụ 15-20 mPa·s. Ọ bụrụ na viscosity na-efegharị, dozie ya na mmiri deionized (iji belata) ma ọ bụ tinye thickener (iji bulie).

Ntụle kwụsiri ike - Nchekwa & ntụkwasị obi ụgbọ njem

Ntụle nkwụsi ike na-eme ka emulsion ahụ bụrụ otu n'oge nchekwa na njem. A na-eji ụzọ nnwale eme ngwa ngwa iji mee ka ọnọdụ dị ogologo oge.

Usoro ngafe/ọdịda:

• Enweghị delamination a na-ahụ anya, sedimentation, ma ọ bụ nhazi gel

• Mgbanwe viscosity <10% site na mbụ

• Mgbanwe nha nha D50 <15%

Ndụ ndu ndu: N'okpuru nchekwa kwesịrị ekwesị (10-30 Celsius, akara), PTFE emulsion na-edobe nkwụsi ike maka ọnwa 6-12. Ọ bụrụ na ule centrifuged gosiri> 5% sedimenti, tụfuo ogbe ahụ.

Nlele ọdịdị - Nyochaa nkwekọ nke ogbe ọsọ ọsọ

Lelee nlele anya n'okpuru ìhè eke.

Ọdịdị anabatara: Emulsion na-acha ọcha ma ọ bụ ìhè na-acha odo odo, otu, na-enweghị ihe ọ bụla dị ka delamination, lumps gel, nhazi akpụkpọ ahụ, ma ọ bụ mmiri ozuzo doro anya.
