PTFE Tape Adhesion vs Mocheso: Mokhoa oa ho Ntlafatsa

Jiangsu Aokai New Materials, moetsi oa profeshenale oa PTFE tepi ea mocheso o phahameng, o arolelana le uena lintlha tsa profeshenale.

Theipi ea PTFE (Teflon) ea mocheso o phahameng ka kakaretso e ka sebelisoa ka mokhoa o tsoelang pele mochesong oa -196 ℃ ho isa ho 260 ℃ . Lits'ebetsong tse ngata, moeli oa ho hanyetsa mocheso oa tepi o thibetsoe ke lera la sekhomaretsi  ho e-na le karoloana ea PTFE. Ts'ebetso ea eona e latela melao e hlakileng e amanang le mocheso:

Ts'ebetso ea sekhomaretsi e fokotseha ha mocheso o ntse o phahama  Ka mocheso o ntseng o eketseha, sekhomaretsi se ntse se nolofala butle-butle, sea qhekella esita le ho senyeha, se lebisang ho fokotseng matla a momahano. Macroscopically, sena se iponahatsa e le ho theoha ha ho khomarela.

Mehato ea ts'ebetso e khethoa ke mofuta oa sekhomaretsi  Likhomaretsi tse fapaneng li na le mocheso o fapaneng haholo oa ho hloleha:

 

Ho ntlafatsa nako ea ho ts'oara mocheso o phahameng , optimization e etsoa haholo-holo ho tsoa likarolong tse tharo: sebopeho sa sekhomaretsi, ts'ebetso ea substrate, le sebopeho sa maqhama a sefahleho.

1. Sekhomaretsi sa Sekhomaretsi: Ntlafatsa Khokahanyo e Fokolang

·  Khetha sekhomaretsi sa sekhomaretsi se hanyetsanang le mocheso o phahameng : E-ba pele ho sekhomaretsi se nang le khatello ea silicone bakeng sa maemo a nako e telele a mocheso o phahameng oa ho sebetsa.

:  Phetoho ea Fluorocarbon Fetola sekhomaretsi sa silicone ka metsoako ea fluorocarbon ho phahamisa mocheso oa phetoho ea khalase (Tg) ho isa ho 230 ℃. Kamora lihora tse 48 tsa ts'ebeliso e tsoelang pele ho 260 ℃, sekhahla sa ho khomarela se ntse se feta 85%.

·  Hlahisa marang-rang a marang-rang : Theha marang-rang a nano-scale crosslinking ho matlafatsa haholo matla a momahaneng le ho hanyetsa ho kuta ha lera la sekhomaretsi mochesong o phahameng.

·  Eketsa thermal stabilizers : Kenyelletsa phenol e thibelitsoeng le li-stabilizers tse ling tsa mocheso ka har'a foromo ho thibela ka katleho ho senyeha ha oxidative tlas'a mocheso o phahameng.

2. Substrate Layer: Phahamisa moeli oa kakaretso oa ho hanyetsa mocheso

·  Phetoho ea nano-filler : Eketsa nano silika, boron nitride nanotubes le li-nanoparticles tse ling ka har'a substrate ea PTFE ho theha lintlha tse amanang le 'mele. Thempereichara ea ho khopamisa mocheso e ka eketseha ka 20-30 ℃, ha e ntse e boloka ho feta 90% ea ho khomarela qalong ho 260 ℃.

·  Phekolo ea crosslinking ea limolek'hule : Liketane tsa limolek'hule tsa Crosslink PTFE ho phahamisa mocheso o tsoelang pele oa tšebeletso ho fihlela ho 300 ℃.

:  Matlafatso ea Fiber Eketsa 25% fiber ea khalase kapa fiber ea carbon ho matlafatsa khanyetso ea creep ka 300%, e nolofalletsang tšebeliso e tsoelang pele ho fihla ho 280 ℃.

3. Sebopeho le Sebopeho sa Sebopeho: Ntlafatsa botsitso ba maqhama

·  Substrate surface treatment : Sebelisa plasma kapa etching ea lik'hemik'hale holim'a PTFE ho eketsa bohlasoa le ts'ebetso ea holim'a metsi, ho matlafatsa ho khomarela sefahleho le ho qoba delamination mocheso o phahameng.

·  Eketsa lera la thibelo e bohareng : Kenya lera la ho itšehla thajana la polyimide (PI) pakeng tsa substrate ea PTFE le sekhomaretsi ho thibela ho kenella ha sekhomaretsi le ho falla tlas'a mocheso o phahameng, ho ntlafatsa botsitso ba sebopeho ka kakaretso.

·  Ntlafatsa sebopeho sa motsoako : Amohela sebopeho sa likarolo tse ngata: PTFE coating + reinforcing substrate + high-themperature stable layer , ho leka-lekanya ho hanyetsa mocheso le ts'ebetso ea sekhomaretsi ka botlalo.

·  Sebaka sa tumello ea ho atolosa mocheso : Coefficient ea katoloso ea PTFE e ka ba makhetlo a 10 ho feta ea tšepe.

Beha sekheo sa 0.15–0.3 mm  moralong oa sebopeho ho lokolla khatello ea mocheso hantle.
