Ndlela Yo Kambela Khwalithi ya PTFE Emulsion: 6 Swikombiso swa Nkoka & Maendlelo

Ku langutiwa: 0 Mutsari: Muhleri wa Sayiti Nkarhi wo kandziyisa: 2026-05-27 Masungulo: Ndhawu

PTFE emulsion – leyi tivekaka tani hi PTFE dispersion – i raw material yo peta fiberglass fabric kuva yi humelerisa PTFE high-temperature fabric , tithepi, na mabandhi. Loko khwalithi ya emulsion yi timiwile, xiendliwa xohetelela xitava na matirhelo yoka yanga kahle ya non-stick, ku peta lokunga ringaniki, kumbe ku tsandzeka ka nkarhi.

Kambe u swi tivisa ku yini loko batch ya PTFE emulsion yi ri kahle? U swi ringeta.

Aokai PTFE yi tirhise no kambela ti emulsions ta PTFE kuringana malembe. Nkongomiso lowu wu katsa swikombiso swa tsevu swa nkoka swa ku kamberiwa – nhlayo leyi tiyeke, pH, vukulu bya swiphemuphemu, ku tsindziyela, ku tshamiseka, na ku languteka – na tindlela ta ntolovelo na swipimelo swo amukela.

Nhundzu leyi Tiyeke – Xikombiso xa Masungulo Swinene

Nhlayo ya swilo swo tiya yi khumba hiku kongoma matirhelo ya swihumelerisiwa xikan’we na ikhonomi ya matirhiselo (swifunengeto swo tiya swilava swilo swo tiya swale henhla).

Maendlelo lama tolovelekeke yo kambela:

Ndlela	Humelerisa	Best For
Ndlela ya Gravimetric (Oven).	Omisa xikombiso xa nhlayo eka 120-150°C kuya eka ntiko lowu nga cinciki; hlayela nhlayo leyi tiyeke hi ku hambana ka vukulu	Xiyimo xa xikhale, lexi tirhisiwaka hinkwako, xa le lab
Ndlela ya Hydrometer	Pima hi hydrometer ya nghilazi (range 1.400-1.600, ku pakanisa ±0.001); hundzuluxa hi ku tirhisa curve ya calibration ya nhundzu yo karhi ya gravity-solid	Ku olova, ku hatlisa ku kamberiwa ka vuhumelerisi endhawini
Ndlela ya Mhaka leyi nga Cinciki	Ku cinca cinca ndzhongho nati surfactants eka mahiselo yale henhla (xikombiso, 380°C); yitlhela yi kumisisa nhlayo ya surfactant	Loko ku laveka nxopaxopo wa surfactant

Swipimelo swo amukela: .

Hi standard T/FSI 067-2021: Xilaveko xa nhlayo yo tiya eka PTFE concentrate leyi cheriweke hiku phindha-phindha i 60±2% .
Mpimo wa xiviri wa vulawuri bya le ndzhawini: 60±0.5% (ku tiyisela loku tiyisiweke eka ku peta loku nga cincekiki)

Nhlayo ya pH – Xikombiso xa ku tshamiseka

Nhlayo ya pH yi khumba ku tiya ka vuhlayiselo, ku bola, na ku fambisana na switirhisiwa swin’wana.

Ndlela yo kambela: Ndlela ya Glass Electrode (Direct Determination) – pima hiku tirhisa pH meter na glass electrode leyi kalibiweke hiku tirhisa kalibration ya tinhla timbirhi kumbe tinharhu. Leyi i ndlela leyi tolovelekeke leyi tirhisiwaka ngopfu.

Swipimelo swo amukela: .

Hi T/FSI 067-2021: pH yale xikarhi ka 9.0 – 11.0
Ku cinca cinca ka pH switala ku kombisa ku nga tshamiseki ka sisiteme kumbe ku cinca cinca ka ti khemikhali ku humelerile (xikombiso, hydrolysis ya surfactant) .
Ku landzelerisa nkarhi woleha ka ku cinca ka pH swina nkoka eka ku avanyisa ku tiya ka ti khemikhali ta emulsion

Leswaku hikokwalaho ka yini pH yiri ya nkoka: Ti emulsions ta PTFE ti tiyisisiwa hi ti fluorinated surfactants, leti lavaka swiyimo swa alkaline (pH > 8) leswaku tita tshama tiri karhi ti tirha. Loko pH yihunguteka ehansi ka 8, emulsion yinga coagulate.

Aokai PTFE yi ringanyeta ku kambela pH eka xigubu xin’wana na xin’wana lexi nghenaka na n’hweti na n’hweti hi nkarhi wa vuhlayiselo. Ku hunguteka ka xitshuketa kusuka eka 10.2 kuya eka 8.5 eka mavhiki mambirhi swikomba leswaku emulsion ayi tshamiseka naswona yifanele kutirhisiwa hiku hatlisa kutani yi ariwa.

Vukulu bya Swiphemuphemu & Ku hangalasiwa ka Vukulu bya Swiphemuphemu

Vukulu na ku fana ka ku hangalasiwa ka swiphemuphemu swa masungulo swa PTFE swina nkucetelo wa xiboho eka swivumbeko swo vumba filimi, ku nghenelela, na matirhelo yohetelela ya xiendliwa.

Maendlelo yo kambela: .

Ndlela	Nsinya wa nawu	Ndhawu yo pima	Best For
Ku hambanisiwa ka Laser	Laser scattering angle yi fambelana na vukulu bya ti particle	Submicron ku ya eka milimitara	Swi tolovelekile ngopfu, swo hatlisa, swo anama
Ku hangalasiwa ka ku vonakala loku cinca-cincaka (DLS) .	Ku xopaxopa ku cinca-cinca ka matimba ya ku vonakala loku hangalakeke hi ku famba ka nkarhi	Submicron na nanoscale	Swiphemuphemu swa masungulo, ku hangalaka loku nga ni mati
Microscopy ya Elektroniki yo Skena (SEM) .	Ku teka swifaniso hiku kongoma – cinca emulsifier hi sodium hexametaphosphate solution kuva ku papalata agglomeration hinkarhi wa ku omisiwa	Xiboho xa le henhla	Vuxokoxoko bya mofoloji, ku pima loku kongomeke

Swikombiso swa nkoka swa nkambisiso: .

D50 (median diameter) – ndzhawu leyi tolovelekeke ya PTFE emulsion: 0.1-0.3 microns
Ku anama ka ku hangalasiwa ka vukulu bya ti particle – kutsongo swa antswa eka ku peta loku nga cincekiki
D10 na D90 – swi hlamusela ku hangalaka ka ku hangalasiwa

Nkongomiso wo amukela: Eka switirhisiwa swotala swa coating, D50 yifanele kuva exikarhi ka 0.15 na 0.25 μm na 90% wa ti particles endzeni ka ±0.1 μm ya xiringaniso.

Viscosity – Ku tirhisiwa ka vumaki

Viscosity yihlawulela mahanyelo ya flow, hiku kongoma yi khumba maendlelo ya coating na impregnation.

Maendlelo lama tolovelekeke yo pima:

Ndlela	Nsinya wa nawu	Ku faneleka
Viscometer ya ku rhendzeleka	Ku pima dynamic viscosity hiku tirhisa rotor resistance	Switala kuva – switirha eka swihalaki swa Newton na leswingariki swa Newtonian
Xipima-viscometer xa Capillary	Yi pima nkarhi wo khuluka hi capillary	Swihalaki swa viscosity yale hansi
Viscometer ya Cone-Plate	Nxopaxopo wa matirhelo ya shear lowu kongomeke	Swihalaki swa viscosity yale henhla, ti rheological curves
Rheology leyi heleleke	Ntshikelelo wa ku tsemeka-nhlayo ya ku tsemeka, thixotropy, ntshikelelo wa mbuyelo, G' na G''.	Loko swilaveko swa ku lulamisa swi lava

Swipimelo swo amukela: .

Hi T/FSI 067-2021: Nhlayo ya viscosity 12.0 – 30.0 mPa·s (eka 25±1°C) .
Viscosity leyinga ehansi swinene → ku peta lokunga ringaniki, ku thona
Viscosity leyinga e henhla swinene → ku nghena kahle eka fiberglass, swilava dilution

Xitsundzuxo lexi tirhaka: Eka dip coating ya fiberglass fabric, target viscosity hi ntolovelo i 15-20 mPa·s. Loko viscosity yi khuluka, lulamisa hi mati lawa yanga deionized (ku hunguta) kutani u chela thickener (ku tlakusa).

Ku Kamberiwa ka Ntshamiseko – Ku Tshembeka ka Vuhlayiselo & Vutleketli

Ku kamberiwa ka ku tiya switiyisisa leswaku emulsion yitshama yiri yin’we hinkarhi wa nhlayiso naku fambisiwa. Maendlelo yo hatlisa yo kambela ya tirhisiwa ku tekelela swiyimo swa nkarhi wo leha.

Ndlela yo Kambela	Swiyimo	Leswi Yi Swi Tekelelaka
Ku tshamiseka ka Centrifugal	1000-5000 rpm kuringana 30-120 wa timinete; languta delamination/sedimentation	Ku dyuhala hi xihatla – ndlela leyi tolovelekeke swinene
Kutshamiseka ka kuhisa	40-60°C kuringana 24-72 wa tiawara	Ku hlayisiwa ka mahiselo yale henhla
Ku tshamiseka ka Freeze-Thaw	Ku titimela eka -20 kuya eka -10°C, ku titimela eka 25°C; phindha 3-10 wa swirhendzevutani	Vutleketli bya xixika hi tilori leti nga hisiwiki
Ku tshamiseka ka Vuhlayiselo	4-40°C kuringana 1-12 wa tinhweti; ku kambela swikombiso swa nkoka nkarhi na nkarhi	Ku kumisisa vutomi bya xelufu lebyi tirhaka
Ku tshamiseka ka Michini	Ku tsemeta hi rivilo lerikulu; xikambelo xa vukulu bya swiphemuphemu/ku cinca ka viscosity	Ku pompa, ku hlanganisa, ku peta hi high-shear

Swipimelo swa ku pasa/ku tsandzeka:

Ku hava delamination leyi vonakaka, sedimentation, kumbe ku endliwa ka gel
Ku cinca ka viscosity < 10% kusuka eka masungulo
Vukulu bya swiphemuphemu D50 ku cinca < 15% .

Nkongomiso wa vutomi bya xelufu: Ehansi ka vuhlayiselo lebyi faneleke (10-30°C, yi pfaleriwile), PTFE emulsion hi ntolovelo yi hlayisa ku tshamiseka kuringana 6-12 wa tinhweti. Loko centrifuged test yikombisa >5% wa sediment, lahla batch.

Ku kamberiwa ka ku languteka – Ku kamberiwa ka ku ringanana ka ntlawa hi ku hatlisa

Kambela xikombiso hi mahlo ehansi ka ku vonakala ka ntumbuluko.

Ku languteka loku amukelekaka: Emulsion yo basa kumbe yo tshwuka yo dzwihala, leyi fanaka, leyi nga riki na swilo leswi nga tolovelekangiki swo fana na delamination, gel lumps, ku vumbiwa ka nhlonge, kumbe mpfula leyi nga erivaleni.

Leswi u faneleke u swi languta:

Ku va munyama → ku thyakisa loku nga kotekaka kumbe ku onhaka ka mahiselo
Nhlonge ehenhla → ku oma kumbe ku hlangana ka xiphemu
Swirhumbana kumbe grit → coagulated polymer (yo biha) .
Mati yo basa ehenhla → sedimentation yi humelerile
