Tataiso ea Khetho bakeng sa Theipi e Phahameng ea Mocheso ea PTFE bakeng sa ho Demolding le Lits'ebetso tsa Anti-Stick tsa Mechini ea Mold ea Ente.

Jiangsu Aokai New Materials, moetsi ea hloahloa oa PTFE le lihlahisoa tsa fluoroplastic, o arolelana mekhoa ea khetho ea tepi ea mocheso o phahameng oa PTFE bakeng sa maemo a ho heletsa le a khahlanong le lithupa lisebelisoa tsa ho bopa ente.

I. Kgetho e Thehilweng ka Mocheso: Tsepamisa Maikutlo hodima Mocheso o hananang le Lera la Sekgomaretsi le Substrate.

Theipi ea PTFE e na le likarolo tse peli: substrate (ka kakaretso lesela la fiberglass le koahetsoeng ka PTFE) le sekhomaretsi se tšehetsang. Hangata lera la sekhomaretsi ke bothata ba ts'ebetso.

1. Mocheso o sa khaotseng oa ho sebetsa ≤ 260 ° C (lipolasetiki tse akaretsang le lipolasetiki tsa boenjiniere tse sa fellang)

Lisebelisoa tse sebetsang: PE, PP, PS, ABS, PVC e bonolo, EVA, hammoho le PA, PBT le lisebelisoa tse ling tse sebetsoang ka mocheso o tlase. Khetho e khothalelitsoeng: Theipi e tloaelehileng ea fiberglass e matlafalitsoeng ea PTFE e nang le sekhomaretsi sa silicone se nang le khatello ea maikutlo (PSA). Botenya bo sisintsoeng: 0.13 mm kapa 0.18 mm, ho lumellana le ho leka-lekana le ho tšoarella ha litšebeletso. Lintlha tsa bohlokoa: Ona ke mofuta o nepahetseng oa ho sebetsa oa PTFE tepi, e nang le botsitso bo botle ba lik'hemik'hale le ts'ebetso ea tokollo.

2. Mocheso o tsoelang pele oa ho sebetsa 260°C ~ 300°C (lipolasetiki tsa boenjiniere tsa mocheso o phahameng)

Lisebelisoa tse sebetsang: PC, PA66, POM, PET, PPA ea mocheso o phahameng, PPO e fetotsoeng le mefuta e meng ea ente e phahameng ea mocheso. Khetho e khothalelitsoeng: Theipi ea Fiberglass PTFE e entsoeng ka sekhomaretsi sa silicone se hanyetsanang le mocheso o phahameng. Sekhomaretsi se tloaelehileng sa silicone se tla tsofala ka potlako, se lahleheloe ke matla 'me se tlohele masala tlas'a mocheso ona. Botenya bo sisintsweng: 0.18 mm kapa 0.25 mm. Likhomaretsi tse teteaneng le likaroloana tsa substrate li fana ka buffer e betere ea mocheso le ho se mamelle. Netefatso e Bohlokoa: Hlalosa litsamaiso tsa sekhomaretsi tse hanyetsanang le mocheso oa nako e telele ho feta 280 ° C ho barekisi, 'me u netefatse hore na sekhomaretsi se tla silafatsa hlobo tlas'a mocheso o phahameng.

3. Mocheso o phahameng oa hang-hang oa 300 ° C ~ 400 ° C (Polasetiki e khethehileng ea mocheso o phahameng kapa libaka tse chesang tsa sebakeng seo)

Lisebelisoa tse sebetsang: PEEK, LCP, PPS, PEI, haholo-holo e fumanoang haufi le li-nozzles tse chesang tse chesang le lihlooho tsa 'extrusion die heads'. Tlhokomeliso ea khetho: Ha ho sekhomaretsi se tšepahalang se mamellang khatello se ka mamellang mofuta ona oa mocheso. Theipi efe kapa efe ea PTFE e tšehelitsoeng ka sekhomaretsi e tla hloleha hang hang, e be carbonize le ho silafatsa lihlahisoa tse felileng. Litharollo tse ling:

1. Lesela la fiberglass la PTFE le se nang sekhomaretsi, le tsitsitsoeng ka mochini ka liforeimi tse koalang hlobo, likhoele kapa likhomaretsi tse nang le mocheso o phahameng oa mocheso (likhomaretsi tse se nang khatello ea maikutlo joalo ka li-silicone sealants).

2. Theipi ea filimi ea Fusible e nang le fluorinated ka ho feletseng ea PFA, e hokeletsoeng holim'a hlobo ka ho cheseletsa moea o chesang. E mamella 260 ° C e tsoelang pele le ho pepeseha ha nako e khutšoanyane ea 300 ° C, leha ho le joalo e ke ke ea nkeloa sebaka ka mokhoa o feto-fetohang joaloka tepi e ikamahanyang le eona. Tlhahiso e 'ngoe e ntlafalitsoeng: Bakeng sa maemo a joalo a mocheso o phahameng, ho khothaletsoa ho roala hlobo PTFE kapa nano ceramic high-themperature coating.

II. Khetho e Thehiloeng ho Thepa ea Thepa: Match Wear Resistance, Corrosion Resistance le Litlhokahalo tsa Tokollo.

Lintho tsa 'mele le lik'hemik'hale tsa polasetiki e qhibilihisitsoeng li etsa qeto ea hore na ho hlokahala eng holim'a ts'ebetso le matla a sebopeho sa tepi.

1. Lisebelisoa tse tacky / hlobo tse tloaelehileng haholo

Lisebelisoa tsa moemeli: EVA, sekhomaretsi se chesang se qhibilihisang, TPE, TPU, limaraka tse itseng tse fetotsoeng tsa PP. Lintlha tsa bohlokoa tsa khetho: Khetha tepi e lokollotsoeng haholo e nang le litaba tse phahameng tsa PTFE le litlolo tse teteaneng. Beha pele theipi e hloekileng ea filimi ea PTFE (ntle le matlafatso ea khalase ea fiberglass, matla a tlase, e loketseng libaka tse nang le khatello e tlase) kapa tepi ea PTFE e kentsoeng ka botlalo. Libaka tse haufi le PTFE tse hloekileng li fana ka ts'ebetso e phahameng ea anti-stick.

2. Glass fiber / diminerale e tlatsitsoeng thepa e matlafalitsoeng

Lisebelisoa tsa moemeli: Fiber ea khalase e matlafalitsoeng PA, PP, PBT, calcium carbonate e tletseng PP. Mokhoa oa ho roala: Melt e phallang e sebetsa joalo ka sandpaper ea metsi, e senya ka potlako liphahlo tse tloaelehileng tsa PTFE; fiberglass substrate e pepesitsoeng e tla baka bofokoli ba ho khomarela. Lintlha tsa bohlokoa tsa khetho:

1. Botenya ba bohlokoa: Khetha tepi e sa sebetseng ea boima ba 0.25 mm kapa ho feta.

2. Matlafatso ea meralo: Khetha lihlahisoa tse nang le likhoele tse ngata tsa PTFE kapa kalafo e thatafatsang holim'a metsi ho e-na le ho roala ha 'ngoe.

3. Leano la ho khutlisa: Tšoara theipi e le ntho e ka sebelisoang khafetsa bakeng sa maemo a joalo a ts'ebetso, 'me u thehe lipotoloho tsa tlhahlobo ea nako le nako ho e-na le ho phehella bophelo ba ts'ebeletso bo sa feleng.

3. Lisebelisoa tse nang le li-additives tse senyang kapa tse nang le pula

Lisebelisoa tsa moemeli: Hard PVC (e lokolla HCl), metsoako e thibelang lelakabe (brominated, phosphorus-based flame retardant precipitation), lithuso tsa ho sebetsa ka fluorinated. Mokhoa oa ho hloleha: Lipula li senya lera la sekhomaretsi kapa li kenella ka har'a substrate, e leng se bakang ho phatloha ha theipi le delamination.

1. Ho hanyetsa lik'hemik'hale tsa sekhomaretsi: Netefatsa hore sekhomaretsi sa silicone se na le inertness e lekaneng khahlanong le li-acid tse fokolang, li-plasticizers le li-precipitates tse ling.

2. Dense substrate: Khetha teipi e nang le fiberglass e lohiloeng ka thata le ho kenngoa ka PTFE e tiisitsoeng ka botlalo ho thibela ho kenella ha khase / metsi ho senyang sekhomaretsi se tšehetsang.

3. Ntlafatso ea moea: Kopanya moholi oa vacuum kapa li-grooves tse eketsehileng haeba ho hlokahala ho fokotsa ho bokellana ha pula e ngata teiping e tsoang mohloling.

4. Lisebelisoa tse sa tsitsang

Maemo a tloaelehileng: Ho bopa ente ea karolo ea elektroniki, phallo e phahameng ea filimi ea PP. Khetho e khothalelitsoeng: Theipi ea anti-static PTFE (theipi e ntšo ea PTFE e koahetsoeng ka carbon conductive black kapa e khethehileng ea anti-static layer) ho qoba ho ata ha lerōle le likotsi tsa ho tsoa ha electrostatic.

III. Phetoho e Thehiloe ho Lisebelisoa le Maemo a Tšebeliso

1. Ho etsoa ha hlobo ea ente

Li-cavities, slider le lifters: Theipi e atisa ho sebelisoa libakeng tse khomarelang hlobo. Theipi e tšesaane ea 0.13 mm e nang le katoloso e ntle ea hlokahala ho lekana libaka tse kobehileng tse rarahaneng. Qoba li-ejector pins le li-slots tsa moea; e-ba hlokolosi bakeng sa likarolo tse nepahetseng kaha botenya ba theipi bo tla fetola mamello ea sehlahisoa. Lipoleiti tsa semathi se chesang le malebela a li-nozzle: Lithempereichara tse phahameng haholo li sebetsa mona; ke lesela la PTFE feela le entsoeng ka mochini le se nang likhomaretsi le ka sebelisoang ho thibela ho khomarela ha flash. Theipi ea ho iketsetsa sekhomaretsi e thibetsoe ka thata.

2. Li-extruders le lisebelisoa tse tlaase

Melomo / li-outlets tsa Extrusion: Thibela ho bokellana ha qhibidihi le likhoele boema-kepeng ba ho tsoa. Khetha tepi e tšesaane haholo (0.08 mm–0.13 mm) ea tokollo e phahameng ho qoba ho fetola litekanyo tsa die orifice. Koahela theipi ho tloha ka pele ho isa pheletsong ea sephutheloana ho fokotsa ho kenella ha metsi ka har'a lirope. Template ea Pelletizer: E pepesitsoe ka ho toba mochesong o phahameng oa ho qhibiliha le ho khojoa ha fiber ea khalase. Theipi e boima ea 0.25 mm kapa ka holimo e tlama, 'me e laoloa e le ntho e sebelisoang kamehla. Cast film rolls / traction press rolls: Anti-stick ebile ho bonolo ho e hloekisa. Theipi ea PTFE e tšehelitsoeng ka silicone e ka phutheloa ho pota-pota lirolara, kapa li-sleeve tsa fiberglass tsa PTFE tse se nang sekhomaretsi li ka amoheloa. Netefatsa hore mocheso oa theipi o hanyetsana le mocheso oa rolara haeba ho futhumatsa ho ameha.

Lintlha tse ka holimo tsa tekheniki li fanoa ke Jiangsu Aokai New Materials Technology Co., Ltd.
