Moralo oa Sebopeho sa Theipi e Nkoang ea PTFE ea Mocheso o Phahameng oa Mocheso: Ho leka-lekana ho Adhesion le ho Tlosoa Mahala

Mokhoa oa ho Lekanya Matla a Adhesive le Residue Free Remova lA e le moetsi ea hloahloa oa tepi ea mocheso o phahameng oa PTFE, Jiangsu Aokai New Material  e arolelana lintlha tsa litsebi:

Ho finyella tekanyo e phethahetseng ea ho khomarela ka matla  le ho tlosoa ho hloekileng ntle le masala  bakeng sa tepi ea mocheso o phahameng oa PTFE ke mosebetsi o hlophisitsoeng oa boenjiniere. Molao-motheo oa motheo oa moralo o itšetlehile ka mokhoa o nepahetseng oa ho etsa lik'hemik'hale le taolo e tiileng ea ts'ebetso ho fana ka lera la sekhomaretsi le matla a ho kopanya  (intermolecular bonding force ka hare ho sekhomaretsi ka boeona) boemong ba micro level. Sena se nolofalletsa ho hloleha ho kopane  ho e-na le ho hloleha ha sefahleho  nakong ea ho ebola, ho lumella lera la sekhomaretsi hore le arohane ka botlalo ho tloha holim'a substrate ntle le ho siea masala.

1. Sebopeho sa Traditional Classic-Layer Three

Theipi e tlosoang ea mocheso o phahameng oa PTFE e nka moralo o hlalositsoeng hantle oa mekhahlelo e meraro:

1. Phatlalatso Layer

·  Material : Filimi ea PTFE kapa e koahetsoeng ka matla a tlase haholo.

·  Mosebetsi : E fana ka ts'ebetso ea tokollo bakeng sa ho phutholoha habonolo ka foromo ea roll; e fana ka theipi e nang le khanyetso e ntle ea mocheso o phahameng, thepa e khahlanong le lithupa le khanyetso ea kutu ea lik'hemik'hale.

2. Ho tšehetsa Substrate

·  Material : Haholo-holo lesela la fiberglass joalo ka skeleton ea sebopeho; PTFE skived film or composite structures of both also used for general-grade applications.

·  Mosebetsi : E fana ka matla a phahameng a tsitsipano, botsitso ba sebopeho le ho hanyetsa meokho, ho boloka sebopeho se tsitsitseng esita le tlas'a mocheso o phahameng o tsoelang pele.

3. Core Adhesive Layer

Ena ke senotlolo sa ho leka-lekanya ho khomarela le ho tlosoa. Litsamaiso tse peli tse kholo tsa sekhomaretsi li sebelisoa haholo:

Silicone PSA (Pressure Sensitive Adhesive)  Ho hanyetsa mocheso oa nako e telele ho fihla ho 260 ℃, ho hanyetsa nako e khutšoanyane ho feta 280 ℃. E na le matla a ntseng a phahama butle le ts'ebetso e tsitsitseng, e sebelisoang haholo lihlahisoa tsa pele le tikoloho e thata e nang le ho baka khafetsa mocheso o phahameng.

Special Acrylic PSA  Ho hanyetsa mocheso oa nako e telele ho pota 180 ℃, e phekolehang ka mocheso o tlase oa ho baka (ka tlase ho 120 ℃) ​​ho fokotsa haholo tšebeliso ea matla a tlhahiso. E fana ka matla a matla a tlamahano le ts'ebetso ea litšenyehelo, e loketseng maemo a kopo ea mocheso o mahareng.

4. Adhesive Layer Balance: Micro Formulation Design Strategy

Tekanyo e ipapisitse le moralo o ntlafalitsoeng oa liforomo tse nyane:

Soft and Hard Monomer Composite Design  Li-polymers li entsoe ka polymerized ho tloha monomers e bonolo  (mohlala, butyl acrylate bakeng sa tack ea pele), li-monomers tse thata  (mohlala, vinyl acetate bakeng sa matla a sebopeho), le li-monomers tse sebetsang  (mohlala, asiti ea acrylic bakeng sa ho hanyetsa mocheso o matlafalitsoeng le momahano).

Hantle-ntle Controlled Crosslinking Density  Trace crosslinking agents (tse kang isocyanates) ba etsa marokho a molek'hule ho haha ​​​​mohaho oa marang-rang oa 3D, ho ntlafatsa haholo momahano oa sekhomaretsi. Ena ke tiisetso ea mantlha ea ho tlosoa habonolo le ho thibela ho taboha ha sekhomaretsi le masala a setseng.

5. Tiisetso ea Boleng ba Bohlokoa Tlhahisong le Tšebelisong

Ts'ebetso ea Premium e boetse e ipapisitse le tlhahiso e nepahetseng le ts'ebeliso e tloaelehileng:

Ts'ebetso ea ho Koala le ho Fokotsa  Mocheso oa ho folisa le nako ka mor'a ho roala ka sekhomaretsi ke tsa bohlokoa. Pheko e sa lekaneng e fokotsa haholo momahano mme e baka masalla. Ho sa le joalo, pretreatment e khethehileng ea holim'a metsi (joalo ka kalafo ea sodium) e sebelisoa ho PTFE ho matlafatsa maqhama a lik'hemik'hale pakeng tsa sekhomaretsi le substrate.

Tataiso ea Ts'ebetso  Sebaka sa ho kopanya se tlameha ho hloeka le ho omella. Mocheso o nepahetseng oa kaho o tloha ho 15 ℃ ~ 40 ℃. Qoba ts'ebeliso e ka tlase ho 10℃ e lebisang ho se lekane ha ho qala, kapa ka holimo ho 50℃ e leng ho eketsang kotsi ea sekhomaretsi se setseng.

6. Kakaretso

Moralo oa theipi ea mocheso o phahameng oa PTFE ha e le hantle o fihlela momahano o fetang ho khomarela  ka mokhoa o nepahetseng oa ho ntlafatsa sebopeho sa limolek'hule. Ha se katleho e le 'ngoe ea tekheniki, empa ke tharollo e hlophisitsoeng e akaretsang tlhahiso ea lik'hemik'hale, theknoloji e ncha ea thepa, tlhahiso e nepahetseng le ts'ebeliso e tloaelehileng. Qetellong, e hlokomela tlamahano e tsitsitseng e tiileng le ho ebola ho hloekileng ho se nang masala tlas'a maemo a ts'ebetso a phahameng haholo a mocheso.
