Indlela Yokuhlola Ikhwalithi Ye-Emulsion ye-PTFE: Izinkomba Ezingu-6 Eziyinhloko Nezindlela

I-PTFE emulsion - eyaziwa nangokuthi i-PTFE dispersion - iyimpahla eluhlaza yokumboza indwangu ye-fiberglass ukukhiqiza Indwangu ye-PTFE enezinga eliphezulu lokushisa , amateyipu, namabhande. Uma ikhwalithi ye-emulsion ivaliwe, umkhiqizo wokugcina uzoba nokusebenza okungekona kwenduku okungekuhle, ukumbozwa ngokungalingani, noma ukwehluleka ngaphambi kwesikhathi.

Kodwa wazi kanjani ukuthi iqoqo le-emulsion ye-PTFE lihle? Uyayihlola.

I-Aokai PTFE isebenzise futhi yahlola ama-emulsions e-PTFE iminyaka. Lo mhlahlandlela uhlanganisa izinkomba eziyisithupha zokuhlola eziwumongo - okuqukethwe okuqinile, i-pH, usayizi wezinhlayiyana, i-viscosity, ukuqina, nokubukeka - ngezindlela ezijwayelekile nezindlela zokwamukela.

Okuqukethwe Okuqinile - Inkomba Eyisisekelo Kakhulu

Okuqukethwe okuqinile kuthinta ngokuqondile ukusebenza komkhiqizo nomnotho wohlelo lokusebenza (ama-coatings aminyene adinga okuqinile okuphezulu).

Izindlela zokuhlola ezijwayelekile:

Imibandela yokwamukela:

• Ngokwe-T/FSI 067-2021 ejwayelekile: Imfuneko yokuqukethwe okuqinile kokugxiliswa okuphindaphindiwe kwe-PTFE ngu- 60±2%

• Izinga langempela lokulawula endaweni: 60±0.5% (ukubekezelelana okuqinile kokunamathela okungaguquki)

I-pH Value - Inkomba Yokuzinza

Inani le-pH lithinta ukuqina kwesitoreji, ukugqwala, nokuhambisana nezinye izinto.

Indlela yokuhlola: Indlela ye-Glass Electrode (Ukunqunywa Okuqondile) – sebenzisa imitha ye-pH ene-electrode yengilazi elinganiswe ngamaphoyinti amabili noma amathathu. Lena indlela ejwayelekile esetshenziswa kakhulu.

Imibandela yokwamukela:

• Ngokwe-T/FSI 067-2021: i-pH ibanga 9.0 – 11.0

• Ukushintshashintsha kwe-pH ngokuvamile kubonisa ukungazinzi kwesistimu noma ukusabela kwamakhemikhali kwenzekile (isb., i-hydrolysis of surfactant)

• Ukulandelela isikhathi eside kwezinguquko ze-pH kubalulekile ekwahluleleni ukuzinza kwamakhemikhali e-emulsion

Kungani i-pH ibalulekile: Ama-emulsion e-PTFE aqiniswa ama-surfactants ane-fluorinated, adinga izimo ze-alkaline (pH> 8) ukuze ahlale esebenza kahle. Uma i-pH yehla ngaphansi kwe-8, i-emulsion ingase ihlangane.

I-Aokai PTFE incoma ukuhlola i-pH kuwo wonke amadubhu angenayo kanye nanyanga zonke phakathi nesitoreji. Ukwehla okungazelelwe kusuka ku-10.2 kuya ku-8.5 emasontweni amabili kubonisa ukuthi i-emulsion iyancipha futhi kufanele isetshenziswe ngokushesha noma yenqatshwe.

Usayizi Wezinhlayiya Nokusabalalisa Usayizi Wezinhlayiyana

Ubukhulu nokufana kokusabalalisa kwezinhlayiya eziyinhloko ze-PTFE kunomthelela omkhulu kuzakhiwo zokwakha ifilimu, ukungeneka, nokusebenza komkhiqizo kokugcina.

Izindlela zokuhlola:

Izinkomba zokuhlola ezibalulekile:

• I-D50 (ububanzi obumaphakathi) - ububanzi obujwayelekile be-emulsion ye-PTFE: 0.1-0.3 microns

• Ububanzi bokusabalalisa usayizi we-particle - emincane ingcono ekuhlanganisweni okungaguquki

• I-D10 ne-D90 - ibonisa ukusabalala kokusabalalisa

Umhlahlandlela wokwamukela: Eziningi zezinhlelo zokusebenza zokumboza, i-D50 kufanele ibe phakathi kuka-0.15 no-0.25 μm no-90% wezinhlayiya phakathi kuka-±0.1 μm wencazelo.

Viscosity - Ukucubungula Ukusebenza

I-Viscosity ibonisa ukuziphatha kokugeleza, okuthinta ngokuqondile izinqubo zokumboza kanye ne-impregnation.

Izindlela zokulinganisa ezijwayelekile:

Imibandela yokwamukela:

• I-T/FSI ngayinye 067-2021: Ibanga le-Viscosity 12.0 – 30.0 mPa·s (ku-25±1°C)

• I-viscosity ephansi kakhulu → ukunamathela okungalingani, ukuconsa

• I-viscosity ephakeme kakhulu → ukungena okungalungile ku-fiberglass, idinga ukuhlanjululwa

Inothi elisebenzisekayo: Ngokuhlanganiswa kwe-dip yendwangu ye-fiberglass, i-viscosity eqondiwe ngokuvamile i-15-20 mPa·s. Uma i-viscosity ikhukhuleka, lungisa ngamanzi e-deionized (ukwehlisa) noma wengeze i-thickener (ukuphakamisa).

Ukuhlola Ukuzinza – Isitoreji Nokwethenjelwa Kwezokuthutha

Ukuhlola ukuzinza kuqinisekisa ukuthi i-emulsion ihlala ifana ngesikhathi sokugcina nokuthutha. Izindlela zokuhlola ezisheshisiwe zisetshenziselwa ukulingisa izimo zesikhathi eside.

Indlela yokudlula/yokwehluleka:

• Ayikho i-delamination ebonakalayo, i-sedimentation, noma ukwakheka kwejeli

• Ukushintsha kwe-viscosity < 10% kusukela ekuqaleni

• Usayizi we-particle D50 ushintsho < 15%

Isiqondiso sempilo yeshelufu: Ngaphansi kwesitoreji esifanele (10-30°C, sivalwe), i-emulsion ye-PTFE ivamise ukugcina ukuzinza izinyanga ezingu-6-12. Uma ukuhlolwa kwe-centrifuged kubonisa >5% sediment, lahla inqwaba.

Ukuhlola Ukubukeka - Ukuhlola Ukuvumelana Kweqoqo Elisheshayo

Hlola ngeso lengqondo isampula ngaphansi kokukhanya kwemvelo.

Ukubukeka okwamukelekayo: I-emulsion ephuzi emhlophe noma ekhanyayo, iyunifomu, engenakho okungavamile okufana ne-delamination, izigaxa zejeli, ukwakheka kwesikhumba, noma imvula esobala.

Ongakubuka:

• Ukwenza kube mnyama → ukungcola okungenzeka noma ukonakaliswa kokushisa

• Isikhumba esingaphezulu → ukomiswa noma ukujiya kancane

• Izigaxa noma insila → i-polymer ejiyile (embi)

• Uketshezi olucacile phezulu → ukuvela kwenhlabathi
