Hi swihi ku hambana exikarhi ka ti emulsions ta PTFE leti humelerisiwaka hi maendlelo yohambana hambana ya polymerization (suspension polymerization na dispersion polymerization)?

Xingheniso hi a Muendli wa Lapi ra Mahiselo ya le Henhla ya Teflon eka Ku Hambana Exikarhi ka Ti-Emulsion ta PTFE leti Humelerisiwaka hi Maendlelo yo Hambana ya Polymerization (Suspension Polymerization na Dispersion Polymerization)

I. Ku Hlamuseriwa ko Sungula ka Miehleketo

Eka matirhelo ya ti indasitiri, suspension polymerization ayi koti ku humesa hiku kongoma PTFE emulsion. Emulsion ya xiviri ya PTFE (dispersion) yi humelerisiwa ntsena hi dispersion polymerization (leyi kahlekahle yinga emulsion polymerization). Jiangsu Teflon High-Temperature Fabric Manufacturer u xiya leswaku leyi xavisiwaka 'suspension-method PTFE emulsion' entiyisweni i suspension ya mati leyi endliweke hi ku hangalasa hi michini ti suspension-polymerized resin micropowders. Leswimbirhi swihambana swinene, kusuka eka ntumbuluko wa ti particle kuya eka switirhisiwa swa matirhiselo yohetelela.

II. Ku hangalasiwa ka polymerization: Emulsion ya PTFE yo sungula

1. Xivumbeko xa Swiphemuphemu na ku tshamiseka

Ti particles tina xirhendzevutani hiku hetiseka, leti vumbiwaka hiku agglomeration ya ti primary particles (0.05–0.5 μm) kuya eka ti secondary particles letingana vukulu bya ti particles bya 0.1–0.3 μm xikan’we naku hangalasiwa ka vukulu lebyintsongo swinene. Ku tshamiseka ku nyikiwa hi ti perfluorinated surfactants (PFOA alternatives) leti engeteriweke hi nkarhi wa polymerization. Endlelo ra colloidal ringa tshama ririkarhi ritshamisekile handle ka stratification kuringana malembe naswona rikombisa ku tiya ka kahle eka mechanical shear.

2. Ndzilo wa Molekhuli na Swihlawulekisi swo Vumba Filimi

Ndzilo wa molecular wule henhla swinene (kufika eka mamiliyoni yo hlaya), na crystallinity leyi tlulaka 94% na vuswikoti bya fibrillation byo tiya swinene. Endzhaku ko peta, ku laveka sintering ya mahiselo yale henhla kwalomu ka 380°C, laha hi nkarhi wa kona ti particles ti hlangana kuva film leyi yaka emahlweni, yo enta, na yo tiya leyingana swivumbeko swa kahle swinene swa anti-corrosion na non-stick.

3. Ku Endliwa ka Ntolovelo na Matirhiselo

Ku lulamisiwa swi pimiwile eka paste extrusion, impregnation, kumbe ku peta leswi landzeriwaka hi sintering. Switirhisiwa leswi tolovelekeke swikatsa swifunengeto swa switirhisiwa swo sweka leswinga namarheli, ku cheriwa ka ti fiberglass architectural membranes, ti microporous ePTFE membranes (leti hefemulaka naswona tinga ngheniwiki hi mati), na tifilimi ta xiyimo xale henhla ta capacitor.

III. Suspension Polymerization Micropowders: Ku yimisiwa ka mati (Hakanyingi ku tsariwa hi ndlela yo biha tanihi Emulsion) .

1. Xivumbeko xa Swiphemuphemu na ku tshamiseka

Tani hilaha swinga kombisiwa hakona hi Jiangsu Teflon High-Temperature Fabric Manufacturer: Ti particles ti endliwa hiku sila naku pfotlosa ti suspension-polymerized pellets, leswi endlaka leswaku kuva na swivumbeko leswinga tshamisekangiki swa polyhedral leswingana vukulu bya ti particle kusuka eka 2 kuya eka 20 μm xikan’we naku hangalasiwa ka vukulu byo anama. Endlelo leri ari tshamisekanga hi thermodynamically naswona ritala kuva na sedimentation na stratification. Ti surfactants leti tolovelekeke nati thickeners tofana na xanthan gum na cellulose ethers tifanele ku cheriwa kuva ti hlwela sedimentation, naswona ku hlanganisiwa kahle swa laveka loko kungase tirhisiwa.

2. Ndzilo wa Molekhuli na Swihlawulekisi swo Vumba Filimi

Ndzilo wa molecule wunga lulamisiwa kuya eka ndzhawu yale hansi swinene (makhume ya magidi kuya eka madzana ya magidi), na brittleness leyikulu xikan’we na vuswikoti bya fibrillation lebyi tsaneke swinene. Endzhaku ko peta, ku laveka ntsena ku omisiwa ka ambient kumbe low-temperature drying kuva ku endliwa dry lubricating layer; a yi nge sinteriwa yi va filimi.

3. Ku Endliwa ka Ntolovelo na Matirhiselo

Yinga nghenisiwa hiku kongoma eka ti formulations kutani yi cheriwa hiku peta naku omisiwa hi moya. Switirhisiwa swikatsa swiengeteri swa mafurha ya ti indasitiri, switirhisiwa swo humesa swivumbeko swa rhaba na plastiki, switirhisiwa swo lwisana na ku onhaka na ku rhetela eka ti inks na swifunengeto, na ku hetisa loku nga ngheniwiki hi mati eka swiambalo.

IV. Xikombo xa Xihatla: Ku Hambana ka Nkoka

Masungulo ya Swiphemuphemu

Ti particles ta dispersion polymerization: ti vumbiwile in-situ eka swivumbeko swa xirhendzevutani hiku tirhisa dispersion polymerization;

Ti particles ta ndlela yo yimisa: ti gayeriwa kusuka eka bulk resin kuya eka ti granules letinga tshamisekangiki.

Vukulu bya Swiphemuphemu

Raw dispersion emulsion: 0.1–0.3 μm na ku hangalasiwa ka vukulu bya swiphemuphemu leswintsongo;

Suspension liquid: 2–20 μm na ku hangalasiwa ka vukulu bya ti particle byo anama.

Xitirhisiwa xo tiyisisa

Ku hangalasiwa ka polymerization: switirhisiwa swa le henhla leswi nga na perfluorinated;

Suspension liquid: ti surfactants ta ntolovelo xikan’we na ti thickeners.

Nhundzu yo vumba filimi

Dispersion polymerization: yi endla filimi leyi yaka emahlweni, yo tiya endzhaku ka sintering ya mahiselo yale henhla;

Suspension liquid: ayi endli film, yi tisa ntsena leyara yo oma yo tola.

Switirhisiwa Leswikulu

Dispersion polymerization: swifunengeto leswinga namarheli, swifunengeto swo lwisana na ku bola, tifilimi leti tirhaka;

Suspension liquid: switirhisiwa swo lwisana na ku hlangana, switirhisiwa swo humesa, swiengeteri leswinga onhakiki swa ti inks.

Mahetelelo kusuka eka Jiangsu Teflon High-Temperature Fabric Manufacturer: Loko xitirhisiwa xa wena xilava impregnation, coating sintering, kumbe film formation, ufanele ku hlawula primary PTFE emulsion leyi humelerisiwaka hi dispersion polymerization. Loko u lava ntsena ku antswisa mafurha, swivumbeko swo humesa, kumbe ku tiya ka abrasion handle ko sintering, kutani aqueous suspension leyi endliweke kusuka eka suspension-polymerized micropowders i ndlela leyi faneleke.

Rungula leri nga laha henhla ri nyikiwile hi Jiangsu Aokai Thekinoloji ya Switirhisiwa Leswintshwa Co., Ltd.

Loko u lava ku dyondza swo tala hi vuxokoxoko bya swihlawulekisi, swiyimo swa ku tirhisiwa, na swintshuxo swa ku cinca ka switirhisiwa swa hina hinkwaswo—ku katsa na malapi ya Teflon ya mahiselo ya le henhla, tithepi ta mahiselo ya le henhla ya Teflon, mabandhi ya mesh ya mahiselo ya le henhla ya Teflon, mabandhi lama nga riki na swirhabyani ya muchini wo pfalela, malapi ya PTFE ya tlhelo rin’we, mabandhi yo fambisa ya mahiselo ya le henhla, na malapi ya fiberglass ya mahiselo ya le henhla—hi kombela u ntshunxeka ku hi tihlanganisa hi ku tirhisa leswi landzelaka:

Tilayini ta vukorhokeri bya riqingho:

- Nkulukumba Guo: 18944819998

- Nkulukumba Liu: 13705266308

Minkarhi hinkwayo hi seketela filosofi ya vukorhokeri ya xiphurofexinali na leyi fambiwaka hi vutshembeki, naswona hi tiyimiserile ku ku nyika swintshuxo swa xiyimo xin’we na vukorhokeri byo nyikela nyingiso!
