Uburyo bwo Kugerageza PTFE Emulsion Ubwiza: 6 Ibipimo Byibanze & Uburyo

Emulioni ya PTFE - izwi kandi nka PTFE ikwirakwiza - ni ibikoresho fatizo byo gutwikira umwenda wa fiberglass kugirango ubyare PTFE imyenda yubushyuhe bwo hejuru , kaseti, n'umukandara. Niba ubwiza bwa emulsiyo bwazimye, ibicuruzwa byanyuma bizaba bifite imikorere mibi idakomeye, gutwikira kutaringaniye, cyangwa kunanirwa imburagihe.

Ariko nigute ushobora kumenya niba icyiciro cya emulioni ya PTFE ari cyiza? Uragerageza.

Aokai PTFE yakoresheje kandi igerageza PTFE emulisiyo kumyaka. Aka gatabo gakubiyemo ibipimo bitandatu by'ibizamini - ibirimo bikomeye, pH, ingano y'ibice, ubwiza, ituze, ndetse no kugaragara - hamwe nuburyo busanzwe hamwe n'ibipimo byemewe.

Ibirimo bikomeye - Icyerekezo Cyibanze

Ibirimo bikomeye bigira ingaruka ku buryo butaziguye imikorere yubukungu nubukungu bukoreshwa (impuzu ndende isaba ibintu bikomeye).

Uburyo busanzwe bwo kwipimisha:

Ibipimo byo kwemererwa:

• Kuri T / FSI isanzwe 067-2021: Ibikenewe bikenewe kugirango PTFE yibwe inshuro nyinshi ni 60 ± 2%

• Igipimo nyacyo cyo kugenzura kurubuga: 60 ± 0.5% (kwihanganira cyane kubitwikiriye)

pH Agaciro - Ikimenyetso gihamye

pH agaciro igira ingaruka kububiko, kubora, no guhuza nibindi bikoresho.

Uburyo bwo kwipimisha: Uburyo bwa Glass Electrode Method (Direct Determination) - gupima ukoresheje metero ya pH hamwe na electrode yikirahure ikoresheje kalibibasi cyangwa ingingo eshatu. Ubu ni bwo buryo bukoreshwa cyane.

Ibipimo byo kwemererwa:

• Kuri T / FSI 067-2021: pH urwego 9.0 - 11.0

• Imihindagurikire muri pH akenshi yerekana ihungabana rya sisitemu cyangwa reaction yimiti yabayeho (urugero, hydrolysis ya surfactant)

• Ikurikiranwa rirerire ryimpinduka za pH ningirakamaro mugusuzuma imiterere yimiti ya emulsion

Impamvu pH ifite akamaro: Emulisiyo ya PTFE ihagarikwa na surfactants ya fluor, bisaba imiterere ya alkaline (pH> 8) kugirango ikomeze gukora neza. Niba pH igabanutse munsi ya 8, emulion irashobora gukomera.

Aokai PTFE irasaba gupima pH kuri buri ngoma yinjira kandi buri kwezi mugihe cyo kubika. Kugabanuka gutunguranye kuva 10.2 kugeza 8.5 mugihe cyibyumweru bibiri byerekana ko emulisiyo ihungabana kandi igomba gukoreshwa ako kanya cyangwa ikangwa.

Ingano Ingano & Ingano Ingano Ikwirakwizwa

Ingano nogukwirakwiza uburinganire bwa PTFE ibice byingenzi bigira ingaruka zikomeye kumiterere ya firime, uburyo bworoshye, nibikorwa byanyuma.

Uburyo bwo kwipimisha:

Ibipimo by'ingenzi byo gusuzuma:

• D50 (diameter ya median) - urwego rusanzwe rwa emulioni ya PTFE: microni 0.1-0.3

• Ingano yubunini bwagabanijwe ubugari - bigufi nibyiza kubitwikiriye

• D10 na D90 - biranga ikwirakwizwa ryikwirakwizwa

Amabwiriza yo kwemererwa: Kubisabwa byinshi, D50 igomba kuba hagati ya 0.15 na 0,25 μ mm hamwe na 90% yibice muri ± 0.1 μ m hagati.

Viscosity - Gutunganya Byakoreshwa

Viscosity iranga imyitwarire itemba, bigira ingaruka kuburyo butaziguye no gutwita.

Uburyo busanzwe bwo gupima:

Ibipimo byo kwemererwa:

• Kuri T / FSI 067-2021: Ubuso buri hagati ya 12.0 - 30.0 mPa · s (kuri 25 ± 1 ° C)

• Viscosity iri hasi cyane ating igifuniko kitaringaniye, gitonyanga

• Viscosity iri hejuru cyane → kwinjira nabi muri fiberglass, bisaba kuyungurura

Icyitonderwa gifatika: Kubitwikiriye umwenda wa fiberglass, ubukonje bwintego ni 15-20 mPa · s. Niba viscosity igenda, hindura n'amazi ya deionioni (kumanuka) cyangwa ongeramo umubyimba (kuzamura).

Isuzuma rihamye - Ububiko & Ubwikorezi bwo kwizerwa

Isuzuma rihamye ryemeza ko emulsion ikomeza kuba imwe mugihe cyo kubika no gutwara. Uburyo bwihuse bwo kwipimisha bukoreshwa mukwigana ibihe birebire.

Ibipimo byatsinzwe / gutsindwa:

• Nta gusiba kugaragara, gutembera, cyangwa gukora gel

• Guhinduka kwa Viscosity <10% uhereye kubanza

• Ingano ya D50 ihinduka <15%

Ubuzima bwa Shelf: Mububiko bukwiye (10-30 ° C, bifunze), emulioni ya PTFE ikomeza kugumya amezi 6-12. Niba ikizamini cya centrifuged cyerekana> 5% imyanda, fata icyiciro.

Kugenzura Kugaragara - Kugenzura Byihuse Byihuse Kugenzura

Reba neza icyitegererezo munsi yumucyo usanzwe.

Isura yemewe: Emuliyoni yera cyangwa yoroheje yumuhondo, imwe, idafite ibintu bidasanzwe nko gusiba, ibibyimba bya gel, imiterere y'uruhu, cyangwa imvura igaragara.

Icyo ugomba kureba:

• Umwijima → birashoboka kwanduza cyangwa kwangirika k'ubushyuhe

• Uruhu hejuru → gukama cyangwa coagulation igice

• Ibibyimba cyangwa grit → coagulated polymer (mbi)

• Amazi meza asukuye hejuru → kwibiza byabaye

Incamake - Hitamo uburyo bwikizamini bushingiye kubisabwa

Amakuru yavuzwe haruguru atangwa na Jiangsu Aokai Ibikoresho bishya Ikoranabuhanga Co, Ltd.

Niba wifuza kumenya byinshi kubyerekeranye nibisobanuro birambuye, ibintu bisabwa, hamwe nibisubizo byihariye kubicuruzwa byacu byuzuye, harimo imyenda ya Teflon yubushyuhe bwo hejuru, kaseti ya Teflon yo mu rwego rwo hejuru, imikandara ya meshi yo mu bwoko bwa Teflon, imikandara yimashini idahwitse, umwenda wa PTFE uruhande rumwe, uburyo bwo kwihanganira ubukana bwa fibre,
