Aragtida: 0 Qore: Tifaftiraha Goobta Waqtiga Daabacaadda: 2026-05-27 Asal ahaan: Goobta

Emulsion PTFE - oo sidoo kale loo yaqaano kala firdhinta PTFE - waa alaabta ceeriin ee dahaadhida dharka fiberglass si loo soo saaro. PTFE dhar heerkul sare leh , cajalado, iyo suunyo. Haddii tayada emulsion-ka ay maqan tahay, badeecada ugu dambeysa waxay yeelan doontaa waxqabad aan dhejisnayn oo liita, dahaarka aan sinnayn, ama dhicis dhicis ah.

Laakiin sidee ku ogaan kartaa in dufcaddii emulsion PTFE ay wanaagsan tahay? Waad tijaabinaysaa.

Aokai PTFE waxa ay isticmaashay oo tijaabisay emulsions PTFE sanado. Hagahan waxa uu daboolayaa lixda tilmaame ee tijaabada aasaasiga ah - nuxurka adag, pH, cabbirka walxaha, viscosity, xasiloonida, iyo muuqaalka - hababka caadiga ah iyo shuruudaha aqbalaadda.

Mawduuca Adag - Tusiyaha Ugu Muhiimsan

Mawduuca adag wuxuu si toos ah u saameeyaa waxqabadka alaabta iyo dhaqaalaha codsiga (dahaarka dhumucdiisuna waxay u baahan yihiin adkaha sare).

Hababka baaritaanka caadiga ah:

Habka	Habraaca	Ugu Wanaagsan
Habka Gravimetric (Furno)	Ku qalaji muunad qiyaas ah 120-150 ° C ilaa miisaan joogto ah; ku xisaabi nuxurka adag farqiga tirada badan	Classic, caalami ahaan lagu dabaqi karo, heerka shaybaadhka
Habka Hydrometer	Ku cabbir biyo mitirka dhalada ah (qiyaastii 1.400-1.600, saxnaanta ± 0.001); u beddelo iyada oo loo marayo qalooca cabbirida nuxurka cufis-culus gaar ah	Tijaabada wax soo saarka goobta fudud, degdega ah
Habka Arrinka Aan Kacsan	Dareemi qoyaanka iyo walxaha korkiisa heerkul sarreeya (tusaale, 380°C); sidoo kale waxay go'aamisaa nuxurka surfactant	Marka loo baahan yahay falanqaynta surfactant

Shuruudaha aqbalaadda:

Halbeegga T/FSI 067-2021: Shuruudaha nuxurka adag ee xoogga saarista PTFE ee soo noqnoqda waa 60± 2%
Heerka kontoroolka dhabta ah ee goobta: 60± 0.5% (dulqaad adag ee daahan joogto ah)

Qiimaha pH - Tusiyaha xasiloonida

Qiimaha pH wuxuu saameeyaa xasilloonida kaydinta, daxalka, iyo la jaanqaadka agabyada kale.

Habka Tijaabada: Habka Electrode galaas (Go'aaminta Tooska ah) - cabbir adigoo isticmaalaya mitirka pH oo leh koronto dhalo ah oo lagu qiyaaso laba-dhibcood ama saddex-dhibcood. Tani waa habka caadiga ah ee inta badan la isticmaalo.

Shuruudaha aqbalaadda:

Sida T/FSI 067-2021: pH kala duwan 9.0 - 11.0
Isbeddellada pH inta badan waxay muujinayaan xasillooni darro nidaamka ama falcelinta kiimikaad ayaa dhacay (tusaale, hydrolysis of surfactant)
Dabagalka muddada-dheer ee isbeddellada pH waxay muhiim u tahay in la xukumo xasilloonida kiimikada emulsion-ka

Waa maxay sababta pH ay muhiim u tahay: Emulsions PTFE waxaa xasiliya surfactants fluorinated, kuwaas oo u baahan xaaladaha alkaline (pH> 8) si ay u sii ahaato mid waxtar leh. Haddii pH ay hoos uga dhacdo 8, emulsion-ka ayaa xinjixi kara.

Aokai PTFE waxay ku talinaysaa in lagu tijaabiyo pH durbaan kasta oo soo gala iyo bishiiba inta lagu jiro kaydinta. Hoos-u-dhac lama filaan ah oo ka yimid 10.2 ilaa 8.5 muddo laba toddobaad ah ayaa muujinaysa in emulsion-ku uu xasillooni-darro yahay oo ay tahay in isla markiiba la isticmaalo ama la diido.

Baaxadda Qaybaha & Qaybinta Cabbirka Qaybaha

Cabbirka iyo qaybinta isku midka ah ee qaybaha aasaasiga ah ee PTFE waxay saameyn go'aan ku leeyihiin guryaha sameynta filimada, awood-dhaafka, iyo waxqabadka ugu dambeeya ee alaabta.

Hababka tijaabada:

Habka	Mabda'a	Qiyaasta Qiyaasta	Ugu Wanaagsan
Kala-duwanaanta Laser-ka	Xagasha kala firdhisanaanta leysarka waxay la xiriirtaa cabbirka walxaha	Submicron ilaa milimitir	Inta badan, dhakhso badan, ballaaran
Firfircoonaanta Iftiinka Firfircoonaanta (DLS)	Wuxuu falanqeeyaa isbedbeddelka iftiinka iftiinka ee kala firirsan ee waqtiga	Submicron iyo nanoscale	Qaybaha asaasiga ah, kala firdhiso kala firdhiso
Sawirka Electron Microscope (SEM)	Sawir-qaadista tooska ah - ku beddel emulsifier-ga sodium hexametaphosphate xal si aad uga fogaato xad-dhaafka inta lagu jiro qalajinta	Qaraarka sare	Qaab-dhismeedka faahfaahsan, cabbirka saxda ah

Tilmaamayaasha qiimaynta muhiimka ah:

D50 (dhexroor dhexdhexaad ah) - kala duwanaanshaha caadiga ah ee emulsion PTFE: 0.1-0.3 microns
Baaxadda qaybinta qaybinta - cidhiidhi ayaa u fiican daahan joogto ah
D10 iyo D90 - waxay tilmaamayaan fidinta qaybinta

Tilmaamaha aqbalaadda: Codsiyada dahaarka intooda badan, D50 waa in ay ahaataa inta u dhaxaysa 0.15 iyo 0.25 μm oo leh 90% walxaha gudaha ± 0.1 μm ee celceliska.

Viscosity - Habraaca Codsiga

Viscosity wuxuu tilmaamayaa habdhaqanka socodka, si toos ah u saameeya daaha iyo hababka impregnation.

Hababka cabbirka caadiga ah:

Habka	Mabda'a	Ku habboonaanta
Viscometer wareeg ah	Wuxuu cabbiraa viscosity firfircoon isagoo isticmaalaya iska caabin rotor	Inta badan - waxay u shaqeysaa dareerayaasha Newtonian iyo kuwa aan Newtonian ahayn
Viscometer-ka Capillary	Wuxuu cabbiraa wakhtiga uu ku qulqulayo xididdada dhiigga	Dareeraha viscosity hoose
Cone-Plate Viscometer	Falanqaynta waxqabadka xiirashada saxda ah	Dheecaannada viscosity-sare, qalooca rheological
Rheology dhamaystiran	Heerarka cadaadiska-xiirid, thixotropy, diiqad dhalid, G' iyo G''	Marka shuruudaha habayntu ay dalbanayaan

Shuruudaha aqbalaadda:

Per T/FSI 067-2021: Kala duwanaanshaha viscosity 12.0 - 30.0mPa·s (marka ah 25±1°C)
Viscosity oo aad u hooseeya → daahan aan sinnayn, dhibco
Viscosity oo aad u sarreeya → liidata liidata ee galaasaska, waxay u baahan tahay qas

Xusuusin wax ku ool ah: Dahaarka maro fiberglass ah, viscosity bartilmaameedku caadi ahaan waa 15-20 mPa·s. Haddii viscosity liidid, ku hagaaji biyo deionized (si aad hoos u dhigto) ama ku dar dhumuc (si kor loogu qaado).

Qiimaynta xasiloonida - Kaydinta & Isku halaynta Gaadiidka

Qiimaynta xasilloonida waxay hubisaa in emulsion-ku uu ahaado mid isku mid ah inta lagu jiro kaydinta iyo gaadiidka. Hababka tijaabinta degdega ah ayaa loo isticmaalaa in lagu ekaysiiyo xaaladaha muddada-dheer.

Habka Imtixaanka	Shuruudaha	Waxa ay u ekaysiiso
Xasiloonida Centrifugal	1000-5000 rpm 30-120 daqiiqo; u fiirso delamination/sedimentation	Gabowga degdega ah - habka ugu badan
Deganaanshaha kulaylka	40-60C ilaa 24-72 saacadood	Kaydinta heerkulka sare
Degganaanshiyaha-Dhaaley	Ku qabooji heerkulka -20 ilaa -10 ° C, dhalaali 25 ° C; ku celi 3-10 wareeg	Gaadiidka jiilaalka ee baabuurta xamuulka qaada ee aan kuleylka lahayn
Xasiloonida Kaydinta	4-40 ° C ilaa 1-12 bilood; Tijaabi tilmaamayaasha muhiimka ah xilliyo	Go'aanso nolosha shelf ee waxtarka leh
Dejinta Makaanikada	Xiritaanka xawaaraha sare; Tijaabi cabbirka/muuqaalka beddelka	Bamgareynta, isku dhafka, dahaarka sare ee dhogorta

Shuruudaha Gudbinta/Fashilka:

Ma jiro delamination muuqda, sedimentation, ama samaynta jel
Isbeddelka viscosity <10% bilowga hore
Cabbirka walxaha D50 isbeddelay <15%

Hagida nolosha shelf: Hoosta kaydinta saxda ah (10-30°C, shaabadaysan), PTFE emulsion waxay caadi ahaan ilaalisaa xasiloonida 6-12 bilood. Haddii baaritaanka dhexe uu muujiyo>5% sediment, tuur dufcada.

Kormeerka Muuqata - Hubinta Joogtada Dufcadda Degdega ah

Muuqaal ahaan u baadh muunada iftiinka dabiiciga ah.

Muuqaal la aqbali karo: Emulsion cad ama iftiin jaale ah, labis, oo aan lahayn cillado aan caadi ahayn sida delamination, burooyinka jel, samaynta maqaarka, ama roobab muuqda.

Maxaa la daawado:

Madoobaad → faddarayn suurtagal ah ama xaalufka kulaylka
Maqaarka oogada → qalajinta ama xinjirowga qayb ahaan
Burooyin ama bur → polymer xinjiraysan (xun)
Dareere saafi ah oo sare → sed-bursi ayaa dhacay
