Mawonedwe: 0 Wolemba: Site Editor Nthawi Yosindikiza: 2026-05-27 Origin: Tsamba

PTFE emulsion - amatchedwanso PTFE dispersion - ndi zopangira ❖ kuyanika fiberglass nsalu kupanga PTFE nsalu yotentha kwambiri , matepi, ndi malamba. Ngati khalidwe la emulsion lazimitsidwa, chomalizacho chidzakhala ndi ntchito yosagwira ndodo, ❖ kuyanika mosagwirizana, kapena kulephera msanga.

Koma mumadziwa bwanji ngati mtanda wa PTFE emulsion ndi wabwino? Inu muyese izo.

Aokai PTFE yagwiritsa ntchito ndikuyesa ma emulsions a PTFE kwa zaka. Bukuli lili ndi zizindikiro zisanu ndi chimodzi zoyesera - zolimba, pH, kukula kwa tinthu, kukhuthala, kukhazikika, ndi mawonekedwe - ndi njira zokhazikika komanso zovomerezeka.

Zolimba - Chizindikiro Chodziwika Kwambiri

Zomwe zili zolimba zimakhudza mwachindunji magwiridwe antchito azinthu komanso chuma chakugwiritsa ntchito (zovala zolimba zimafunikira zolimba kwambiri).

Njira zoyesera zodziwika:

Njira	Ndondomeko	Zabwino Kwambiri
Gravimetric (Oven) Njira	Yanikani chitsanzo chochulukira pa 120-150 ° C mpaka kulemera kosalekeza; kuwerengera zolimba ndi kusiyana kwakukulu	Classic, yogwiritsidwa ntchito konsekonse, lab muyezo
Njira ya Hydrometer	Kuyeza ndi galasi hydrometer (kusiyana 1.400-1.600, kulondola ± 0.001); sinthani pogwiritsa ntchito curve yamphamvu yokoka yokhazikika	Kuyesa kosavuta, kofulumira kwapatsamba
Njira Yosasinthasintha	Wonjezerani chinyezi ndi zowonjezera kutentha (mwachitsanzo, 380 ° C); imatsimikiziranso zomwe zili mu surfactant	Pamene kusanthula surfactant chofunika

Zoyenera kulandira:

Pa muyezo wa T/FSI 067-2021: Zofunikira zokhazikika pakukhazikika kwa PTFE mobwerezabwereza ndi 60±2%
Muyezo weniweni wapamalo: 60 ± 0.5% (kulekerera kolimba kwa zokutira kosasintha)

Phindu la pH - Chizindikiro Chokhazikika

Mtengo wa pH umakhudza kukhazikika kosungirako, kuwononga, komanso kugwirizana ndi zinthu zina.

Njira yoyesera: Glass Electrode Method (Kutsimikiza Mwachindunji) - kuyeza pogwiritsa ntchito mita ya pH yokhala ndi electrode yagalasi yoyendetsedwa ndi nsonga ziwiri kapena zitatu. Iyi ndi njira yomwe imagwiritsidwa ntchito kwambiri.

Zoyenera kulandira:

Pa T/FSI 067-2021: pH osiyanasiyana 9.0 - 11.0
Kusinthasintha kwa pH nthawi zambiri kumawonetsa kusakhazikika kwadongosolo kapena kusintha kwamankhwala kwachitika (mwachitsanzo, hydrolysis of surfactant)
Kutsata kwanthawi yayitali kwa kusintha kwa pH ndikofunikira pakuweruza kukhazikika kwamankhwala a emulsion

Chifukwa chiyani pH ili yofunika: Ma emulsion a PTFE amakhazikika ndi ma fluorinated surfactants, omwe amafunikira zinthu zamchere (pH> 8) kuti zikhalebe zogwira mtima. Ngati pH imatsika pansi pa 8, emulsion imatha kugwa.

Aokai PTFE imalimbikitsa kuyesa pH pa ng'oma iliyonse yomwe ikubwera komanso pamwezi posungira. Kutsika kwadzidzidzi kuchokera ku 10.2 mpaka 8.5 pa masabata awiri kumasonyeza kuti emulsion imasokoneza ndipo iyenera kugwiritsidwa ntchito nthawi yomweyo kapena kukanidwa.

Kukula kwa Tinthu & Kukula kwa Tinthu

Kukula ndi kugawa kufanana kwa tinthu tating'onoting'ono ta PTFE kumakhudza kwambiri mapangidwe opanga filimu, permeability, ndi ntchito yomaliza ya mankhwala.

Njira zoyesera:

Njira	Mfundo yofunika	Muyezo Range	Zabwino Kwambiri
Kusintha kwa Laser	Laser kubalalitsa angle correlates ndi tinthu kukula	Submicron mpaka millimeter	Ambiri, mofulumira, osiyanasiyana
Kuwala Kwamphamvu (DLS)	Imasanthula kusinthasintha kwamphamvu kwa kuwala kwanthawi yayitali	Submicron ndi nanoscale	particles oyambirira, kuchepetsa dispersions
Scanning Electron Microscopy (SEM)	Kujambula molunjika - m'malo mwa emulsifier ndi sodium hexametaphosphate yankho kuti mupewe kuphatikizika pakuyanika.	Kukhazikika kwakukulu	Mapangidwe atsatanetsatane, muyeso wolondola

Zizindikiro zazikulu zowunika:

D50 (m'mimba mwake wapakati) - mtundu wanji wa PTFE emulsion: 0.1-0.3 microns
M'lifupi kagawo kakang'ono kagawidwe kake - kucheperako ndikwabwino pakupaka kofanana
D10 ndi D90 - amasonyeza kufalikira kwa kugawa

Malangizo ovomerezeka: Pazovala zambiri, D50 iyenera kukhala pakati pa 0.15 ndi 0.25 μm ndi 90% ya tinthu tating'ono mkati mwa ± 0.1 μm ya tanthauzo.

Viscosity - Kukonzekera Kugwiritsa Ntchito

Viscosity imadziwika ndi machitidwe otaya, omwe amakhudza mwachindunji njira zokutira ndi kuyamwitsa.

Njira zoyezera zodziwika bwino:

Njira	Mfundo yofunika	Kuyenerera
Viscometer yozungulira	Imayezera kukhuthala kwamphamvu kudzera pa kukana kwa rotor	Zofala kwambiri - zimagwira ntchito kumadzi a Newtonian ndi omwe si a Newtonian
Capillary Viscometer	Imayesa nthawi yoyenda kudzera mu capillary	Otsika mamasukidwe akayendedwe zakumwa
Cone-Plate Viscometer	Kusanthula koyenera kwa shear	Madzi othamanga kwambiri, ma rheological curves
Comprehensive Rheology	Kumeta ubweya wometa ubweya, thixotropy, kupsinjika kwa zokolola, G' ndi G''	Pamene zofunika processing ndi wovuta

Zoyenera kulandira:

Pa T/FSI 067-2021: Makanema osiyanasiyana 12.0 - 30.0 mPa·s (pa 25±1°C)
Kukhuthala kotsika kwambiri → zokutira zosagwirizana, kudontha
Makanema owoneka bwino kwambiri → osalowa bwino mu fiberglass, amafunikira kuchepetsedwa

Chidziwitso chothandiza: Pa zokutira za nsalu za fiberglass, kukhuthala kwa chandamale kumakhala 15-20 mPa·s. Ngati mamasukidwe akayendedwe akuyenda, sinthani ndi madzi opangidwa ndi deionized (kutsitsa) kapena kuwonjezera thickener (kukweza).

Kuwunika Kukhazikika - Kusungirako & Kudalirika Kwamayendedwe

Kuwunika kokhazikika kumatsimikizira kuti emulsion imakhalabe yunifolomu panthawi yosungira komanso yoyendetsa. Njira zoyesera zofulumizitsa zimagwiritsidwa ntchito kutengera mikhalidwe yayitali.

Njira Yoyesera	Zoyenera	Zimene Imatsanzira
Kukhazikika kwa Centrifugal	1000-5000 rpm kwa mphindi 30-120; onani delamination/sedimentation	Kukalamba msanga - njira yodziwika kwambiri
Kutentha Kukhazikika	40-60 ° C kwa maola 24-72	Kusungirako kutentha kwambiri
Kukhazikika kwa Freeze-Thaw	Kuzizira pa -20 mpaka -10 ° C, sungunuka pa 25 ° C; kubwereza 3-10 kuzungulira	Zoyendera m'nyengo yozizira m'magalimoto osatenthedwa
Kukhazikika Kosungirako	4-40 ° C kwa miyezi 1-12; yesani zizindikiro zazikulu nthawi ndi nthawi	Dziwani bwino alumali moyo
Kukhazikika Kwamakina	Kumeta mwachangu; kuyesa tinthu kukula / mamasukidwe akayendedwe kusintha	Kupopera, kusakaniza, kumeta ubweya wambiri

Zolinga zopambana/zolephera:

Palibe mawonekedwe a delamination, sedimentation, kapena gel
Kusintha kwa viscosity <10% kuchokera koyamba
Tinthu kukula D50 kusintha <15%

Chitsogozo cha moyo wa alumali: Posungira bwino (10-30 ° C, yosindikizidwa), emulsion ya PTFE imakhala yokhazikika kwa miyezi 6-12. Ngati mayeso a centrifuged akuwonetsa> 5% sediment, taya batch.

Kuyang'anira Mawonekedwe - Kuwunika Kwachangu kwa Batch

Yang'anani mowoneka chitsanzo pansi pa kuwala kwachilengedwe.

Maonekedwe ovomerezeka: emulsion yoyera kapena yopepuka yachikasu, yunifolomu, yopanda zolakwika monga delamination, zotupa za gel, mapangidwe akhungu, kapena mvula yowonekera.

Zowonera:

Kuchititsa mdima → kuipitsidwa komwe kungachitike kapena kuwonongeka kwa kutentha
Khungu pamwamba → kuyanika kapena kutsika pang'ono
Zotupa kapena grit → coagulated polima (zoipa)
Madzi owoneka bwino pamwamba → kusungunuka kwachitika

Chidule - Sankhani Njira Zoyesera Kutengera Ntchito

Ngati muli...	Ganizirani pa mayesowa	pafupipafupi
Kuwunika kwazinthu zopangira	Zolimba, pH, mamasukidwe akayendedwe, mawonekedwe	Gulu lililonse
Kuwongolera khalidwe la kupanga	Zolimba (hydrometer), viscosity (zozungulira), pH	Tsiku lililonse kapena kusintha
Kukula kwa ndondomeko ya zokutira	Kukula kwa tinthu, rheology, kukhazikika	Kusintha kwa kalembedwe
Kuyenerera kwa ogulitsa	Onse asanu ndi limodzi + amaundana-thaw + kusungirako nthawi yayitali	Kotala kapena chaka
Kulephera kusanthula	Kujambula kwa tinthu ta SEM + kukhazikika kwathunthu	Monga kufunikira

Zomwe zili pamwambazi zimaperekedwa ndi Malingaliro a kampani Jiangsu Aokai New Materials Technology Co., Ltd.

Ngati mukufuna kudziwa zambiri za magawo, mawonekedwe ogwiritsira ntchito, ndi njira zosinthira makonda pazogulitsa zathu zonse, kuphatikiza nsalu ya Teflon yotentha kwambiri, tepi yotentha kwambiri ya Teflon, malamba amtundu wa Teflon, malamba osakanizika osakanikirana, mbali imodzi ya PTFE, nsalu yotchinga ndi kutentha kwambiri nsalu , chonde titumizireni kudzera njira zotsatirazi:
