Phapang ke efe pakeng tsa li-emulsion tsa PTFE tse hlahisoang ke mekhoa e fapaneng ea polymerization (ho emisa polymerization le ho hasana ha polymerization)?

Selelekela ka a Moetsi oa Lesela la Teflon e Phahameng ea Mocheso ho Phapang lipakeng tsa PTFE Emulsions e Hlahisitsoeng ke Mekhoa e sa Tšoaneng ea Polymerization (Suspension Polymerization le Dispersion Polymerization)

I. Tlhakiso ea Pele ea Maikutlo

Ts'ebetsong ea indasteri, polymerization ea ho emisoa ha e khone ho hlahisa emulsion ea PTFE ka ho toba. Emulsion ea 'nete ea PTFE (ho hasana) e hlahisoa feela ke ho hasana ha polymerization (eo ha e le hantle e leng emulsion polymerization). Jiangsu Teflon High-Temperature Fabric Manufacturer o hlokomela hore 'suspension-method PTFE emulsion' e fumanehang khoebong ha e le hantle ke ho emisoa ho nang le metsi ho entsoeng ka ho qhalakanya li-micropowder tsa resin polymerized resin. Tse peli li fapane haholo, ho tloha ho tlhaho ho isa ho ts'ebeliso ea ho qetela.

II. Dispersion Polymerization: Primary PTFE Emulsion

1. Particle Morphology le Stability

Likaroloana li pota-potile ka ho phethahetseng, tse entsoeng ke ho kopana ha likaroloana tse ka sehloohong (0.05-0.5 μm) ka likaroloana tsa bobeli tse nang le boholo ba 0.1-0.3 μm le kabo ea boholo bo moqotetsane haholo. Botsitso bo fanoa ke li-perfluorinated surfactants (tse ling tsa PFOA) tse kentsoeng nakong ea polymerization. Sistimi ea colloidal e ka lula e tsitsitse ntle le stratification ka lilemo mme e bonts'a khanyetso e ntle ea ho kuta ka mochini.

2. Boima ba Limolek'hule le Lintho tsa ho Etsa Lifilimi

Boima ba molek'hule bo phahame haholo (ho fihlela ho limilione tse 'maloa), bo nang le crystallinity e fetang 94% le matla a matla a fibrillation. Ka mor'a ho roala, mocheso o phahameng oa mocheso o ka bang 380 ° C oa hlokahala, nakong eo likaroloana li kopanang filiming e tsoelang pele, e teteaneng, le e thata e nang le thepa e babatsehang ea ho thibela ho bola le ho se thupeng.

3. Ts'ebetso e Tloaelehileng le Likopo

Ho sebetsa ho lekanyelitsoe ho peista extrusion, impregnation, kapa coating e lateloang ke sintering. Lisebelisoa tse tloaelehileng li kenyelletsa liphahlo tse sa keneng ka lithupa, ho kenngoa ha li-membrane tsa kaho ea fiberglass, li-membrane tsa ePTFE tse nyane (tse phefumolohang le tse sa keneleng metsi), le lifilimi tse phahameng tsa capacitor.

III. Suspension Polymerization Micropowders: Aqueous Suspension (Hangata ha e Ngotsoe ka Emulsion)

1. Particle Morphology le Stability

Joalokaha ho boletsoe ke Jiangsu Teflon Moetsi oa Lesela le Phahameng la Mocheso: Likaroloana li hlahisoa ka ho sila le ho pshatla li-pellets tse emisitsoeng-polymerized, tse hlahisang libopeho tse sa tloaelehang tsa polyhedral tse nang le boholo ba likaroloana ho tloha ho 2 ho ea ho 20 μm le ho arola boholo bo pharaletseng. Sistimi ena ha e tsitsa ka mokhoa oa thermodynamically mme e na le tšekamelo ea ho ba le sedimentation le stratification. Li-surfactants tse tloaelehileng le li-thickeners tse kang xanthan gum le cellulose ethers li tlameha ho eketsoa ho thibela sedimentation, 'me ho hlokahala ho ts'oara ka botlalo pele ho sebelisoa.

2. Boima ba Limolek'hule le Lintho tsa ho Etsa Lifilimi

Boima ba limolek'hule bo ka fetoloa ho ea boemong bo batlang bo le tlase (mashome a likete ho ea ho makholo a likete), ka brittleness e kholoanyane le matla a fokolang haholo a fibrillation. Ka mor'a ho roala, ho omisoa ha maemo kapa mocheso o tlaase ho hlokahalang ho theha lera le omileng la lubricating; e ke ke ea etsoa filimi.

3. Ts'ebetso e Tloaelehileng le Likopo

E ka kenyelletsoa ka ho toba lihlopheng kapa ho sebelisoa ka ho roala le ho omisoa ka moea. Likopo li kenyelletsa lisebelisoa tsa liindasteri tsa lubricant, rabara le liente tse lokollang hlobo ea polasetiki, li-anti-wear le li-slip bakeng sa li-inks le li-coatings, le masela a thibelang metsi.

IV. Quick Reference: Liphapang tsa Core

Tšimoloho ea Karolo

Dispersion polymerization particles: e entsoe in-situ hore e be libopeho tse chitja ka ho hasanya polymerization;

Likaroloana tsa mokhoa oa ho emisa: fatše ho tloha ho resin e ngata ho ea ho li-granules tse sa tloaelehang.

Boholo ba Karolo

Emulsion e tala ea ho hasana: 0.1-0.3 μm e nang le kabo ea boholo bo moqotetsane;

Mokelikeli o emisitsoeng: 2-20 μm ka kabo ea boholo ba likaroloana tse pharaletseng.

Setsibotsi

Dispersion polymerization: perfluorinated surfactants;

Mokelikeli o emisitsoeng: li-surfactants tse tloaelehileng hammoho le li-thickeners.

Thepa ea ho etsa lifilimi

Dispersion polymerization: e etsa filimi e tsoelang pele, e thata ka mor'a ho chesa mocheso o phahameng;

Mokelikeli o emisitsoeng: ha o etse filimi, o fana feela ka lera le omileng la ho tlotsa.

Lisebelisoa tse ka Sehloohong

Dispersion polymerization: liphahlo tse se nang thupa, li-anti-corrosion linings, lifilimi tse sebetsang;

Mokelikeli o emisitsoeng: li-anti-friction agents, lisebelisoa tsa ho lokolla, li-additives tse thibelang ho apara bakeng sa li-inks.

Qetello e tsoang ho Jiangsu Teflon Moetsi oa Lesela le Phahameng la Mocheso: Haeba kopo ea hau e hloka ho kenngoa, ho roala sintering, kapa ho etsoa ha filimi, u tlameha ho khetha emulsion ea mantlha ea PTFE e hlahisoang ke dispersion polymerization. Haeba o hloka feela ho ntlafatsa lubricity, thepa ea ho lokolla, kapa ho hanyetsa abrasion ntle le sintering, joale ho emisoa ha metsi ho entsoeng ka li-micropowder tse emisitsoeng ke khetho e nepahetseng.
