Ndlela leyi PTFE Tape Cut End Face Structure Xi Khumbaka Ha Yona Ku Adhesive Oozing na Edge Lifting

Rini PTFE high-temperature tape yi cheriwa eka heat sealer, guide roller, kumbe bonding surface, swiphiqo swimbirhi leswi tolovelekeke swinga humelela emakumu: adhesive oozing (glue leyi khulukaka kusuka eka tlhelo leri tsemiweke) na edge lifting (the tape edge yi rhurhumela kusuka eka substrate).

Swihoxo leswi switala ku landzelerisiwa kusuka eka xihlovo xin’we: khwalithi ya maendlelo yo tsemeta (ku tsema). Xivumbeko xa xikandza xa makumu lexi tsemiweke – hambi xi rhetela kumbe xo khwaxa, xi basile kumbe xi delaminated – xi boha ndlela leyi xinamarheti xi tikhomaka ha yona emakumu.

Aokai PTFE yi lawula khwalithi ya slitting ku sivela timhaka leti. Nkongomiso lowu wu hlamusela hilaha end face morphology yivangaka ku khuluka naku tlakuka, na leswaku tlhelo ra tape leri tsemiweke kahle rifanele ku languteka njhani.

Xivumbeko xa Xiphemu xa Xihambano xa Thepi ya PTFE

Ku twisisa ndlela leyi xikandza xa makumu lexi tsemiweke xi khumbaka matirhelo ha yona, rhanga hi ku tsundzuka xivumbeko xa thepi. Thepi ya mahiselo yale henhla ya PTFE hi ntolovelo yi na:

• Xitirhisiwa xa lapi ra fiberglass (ku tiyisisiwa) .

• PTFE coating (xiphemu lexi nga namarheliki) .

• Leyara yo namarhela leyi nga ni ntshikelelo wa silicone (tlhelo ro boha) .

Ku tsemeta swivula ku tsema hiku leha ka xivumbeko lexi xa laminated kuva xiva ti rolls letintsongo. Mofoloji ya xikandza xa makumu lawa ya tsemiweke – xo olova kumbe xo khwaxa, xo kongoma kumbe xa magandlati – na nkarhi hinkwawo wa dimensional (flatness, verticality, adhesive shortage kumbe stringing) swi hlohletela swihoxo leswimbirhi.

Ndlela Leyi Xikandza Lexi Tsemiweke Xa Makumu Xi Vangaka Ku Humelela Ka Namarheta Ha Yona

Ku khuluka ka namarheta swivula ku khuluka lokunga languteriwangiki ka namarheta kusuka eka tlhelo ra thepi, ku thyakisa swiphemu swa ntirho leswi bohiweke kumbe tlhelo ra le ndzhaku ra thepi. Xikandza xa makumu lexi tsemiweke xi endla nkucetelo wo kongoma.

1. Vuyelo byo koka na ku hlanganisa tintambhu ku suka eka ku tsemiwa

Loko slitting blade yiri dull kumbe cutting angle yinga fanelanga, blade yita koka no olovisa flexible silicone PSA ematshan’wini yo tsema kahle. Leswi swi vanga:

• Microscopic glue filaments na ti burrs: Xinamarheti lexi handzukeke xi siya ti ultra-fine glue threads kumbe ti flakes leti humelaka ehandle kusuka eka tape. 'glue whiskers' leti ti hundzisela no tshoveka hiku olova loko ti lulamisiwa kumbe ku hlayisiwa, leswi endlaka leswaku kuva na mbuyelo wa mahlo wa adhesive oozing.

• Ku rhurhela ka adhesive kuya emakumu: Matimba yo koka hinkarhi wa slitting ya koka adhesive kuya eka xikandza xa makumu hambi kuri cross-section ya substrate. Loko thepi yi rhendzeleka kuva roll, xinamarheti lexi humesiweke xi namarhela eka PTFE endzhaku ka leyara leyi nga ekusuhi. Loko ku pfuriwa, glue leyi saleke yi humelela ematlhelo – ku tsandzeka ka classic oozing.

2. Extrusion effect kusuka eka swikandza swa makumu leswinga ringaniki

Swikandza swa makumu leswinga tshamisekangiki kahle (swiphemu leswinga wavy, protrusions, inclined planes) swi rhwala ntshikelelo wa le tlhelo lowu nga tolovelekangiki eka tindzhawu leti tlakukeke loko thepi yi rhendzelekile swinene kuva yiva swirhendzevutani. Silicone PSA i viscoelastic – yi rhendzeleka ehansi ka ntshikelelo lowu nga heriki, ngopfu ngopfu hi nkarhi wa ku hlayisiwa ka mahiselo yale henhla kumbe ku fambisiwa. Ntshikelelo lowu wu endla leswaku adhesive yi khuluka kusuka eka ti high-pressure protrusions kuya eka low-pressure voids, yi tsindziyela kusuka eka xikandza xa makumu.

3. Xisirhelelo xa le tlhelo lexi tshovekeke exikarhi ka xinamarheti na substrate

Ideal slitting yi tisa flush cross-section leyi hlanganisaka ti layers hinkwato. Ku tshoveka lokunga kahle swinga endla leswaku kuva na delamination xikan’we naku hambanisiwa exikarhi ka adhesive na fiberglass, kumbe ti cavities eka cross-section, leswi tshovekaka xivumbeko xa makumu lexi pfaleriweke. Loko swi hisiwa, xinamarheti lexi olovisiweke xi nghena ehandle hi ti micro-channels leti. Eka mahiselo yale henhla (xikombiso, ti heat sealers ehenhla ka 200°C), adhesive fluidity surges, na rough end faces swi tlakusa swinene khombo ra ku khuluka.

Ndlela Leyi Xikandza Xa Makumu Lexi Tsemisiweke Xi Vangaka Ku Tlakusa Makumu

Ku tlakusa matlhelo swivula ku hambanisiwa hiku tisungulela ka matlhelo ya tape kusuka eka swiphemu leswi hlanganisiweke ehansi ka tension kumbe kuhisa endzhaku ka ku cheriwa.

1. Thinned edge adhesive layer – ndzhawu yo boha leyi tsaneke

Dull blades kumbe ti slitting parameters letinga fanelangiki ti humesa compression-cut effect: blade yi tsindziyela swilo etlhelo kutlula ku swi tsemelela hiku basa. Adhesive yi khulukela etlhelo ehansi ka compression, leswi endlaka leswaku kuva na adhesive yo olova swinene kumbe hambi kuri ku kayivela eka tlhelo rale handle swinene. Zone leyi ya marginal yina matimba yale hansi swinene yo boha kutlula miri wa tape, hikokwalaho ku tlakusa edge swisungula laha ehansi ka tension leyintsongo kumbe thermal stress.

2. Ti burrs ta substrate na delamination – mbuyelo wa wedging

PTFE tape substrate yina fibre ya nghilazi. Ku tsemelela loku nga fanelangiki ku koka ti fiberglass filaments ematshan’wini yo ti tsema kahle, leswi siyaka ti fiberglass burrs leti tiyeke emahlweni ka makumu. Hi nkarhi wa lamination, ti hard burrs leti ti seketela tape edge, ti endla swivandla leswintsongo exikarhi ka adhesive surface na workpiece – leswi sivelaka ku khumbana loku heleleke naswona swivanga ku tlakuka.

Loko ku tsemeka swivanga delamination exikarhi ka PTFE coating na fiberglass eka makumu, ti mismatched thermal expansion rates ti humesa ntshikelelo wa le ndzeni endzhaku ko hisa, hiku kongoma ku tshovela matlhelo kusuka eka ti substrates.

3. Serrated kumbe notched edges – ku hlangana ka ntshikelelo

Ti serrations leti vonakaka na ti notches ti khoma moya naswona ti sivela ku khumbana loku heleleke ka le henhla endzhaku ka ku boha. Hambi kuri macroscopically flat edges lawa yanga na micro-unevenness ya kuma uneven thermal expansion loko ya hisiwa, leswi handzulaka bonding interface xikan’we naku hlohletela cascading edge lifting.

4. Ku thyakisa kusuka eka extruded adhesive – reduced edge tack

Xinamarheti lexi khulukaka swinene xi nga ha tlhela xi namarhela emakumu ka thepi, xi cinca swivumbeko swa tikhemikhali ta leyara ya namarheta ya le tlhelo. Trace oil stains leyi hundziseriwaka kusuka eka ti blades na yona yi hunguta edge tackiness – hinkwaswo switirha tani hi ti lifting inducements.

Swilaveko swa Standard End Face – Ndlela yo Sivela ku Oozing na ku Tlakusa

Ku tshikelela adhesive oozing na edge lifting hi xisekelo, slitting end face yifanele ku fikelela swipimelo leswi landzelaka:

1. Xivumbeko xa xivumbeko – xo olova naswona xi tsindziyerile

• Ti fibre ta nghilazi ti tsemiwa kahle handle ko hlangana na swona.

• Leyara yo namarhela, substrate, na PTFE coating swi endla xiphemu xa flat lexi hlanganisiweke.

• Ku hava ku hlanganisiwa ka tintambhu ta glue, ku pfumaleka ka swinamarheti kumbe ku delamination.

2. Ku tshama nkarhi na nkarhi – ku kongoma na ku fana

• Xikandza xa makumu yo kongoma na waviness yitsongo na inclination.

• Ku tiyisisa ku hangalasiwa ka ntshikelelo loku fanaka loko ku rhendzeleka eka swirhendzevutani.

Xikandza xa makumu xo olova, lexi nga onhakiki, lexi nga onhakiki xi tirha tanihi 'seal' ya makumu ya thepi. Yi khiya adhesive layer eka creep migration naswona yitiyisisa vuswikoti byo boha lebyi heleleke eka millimeter yin’wana na yin’wana ya ncila – leswi herisaka oozing xikan’we naku tlakusa eka xihlovo.

Nkatsakanyo – Khwalithi ya ku tsemelela yi khumba hi ku kongoma Matirhelo ya Thepi

Aokai PTFE yi tirhisa switirhisiwa swo tsemeta hi ku kongoma leswi nga na swiphepherhele swo kariha na ti-angle leti antswisiweke ku humesa matlhelo ya thepi lama tengeke, lama rhetaka, naswona lama nga riki na swihoxo. Loko uri na edge oozing kumbe lifting hi ti tape tin’wana, slitting quality yingava xivangelo. Tihlanganisi na hina ku burisana hi xikombelo xa wena.

Vuxokoxoko lebyi nga laha henhla byi nyikiwile hi Jiangsu Aokai Switirhisiwa Leswintshwa Thekinoloji Co., Ltd.

Loko u lava ku dyondza swo tala hi vuxokoxoko bya swihlawulekisi, swiyimo swa xikombelo na swintshuxo leswi endleriweke nxaxamelo wa hina hinkwawo wa swikumiwa, ku katsa na malapi ya mahiselo ya le henhla ya PTFE, tithepi ta mahiselo ya le henhla ya PTFE, mabandhi yo fambisa ya mesh ya PTFE, mabandhi ya muchini wo boha lama nga riki na swirhabyani, lapi ra PTFE ra tlhelo rin’we, mabandhi yo fambisa lama nga lwisaniki na mahiselo ya le henhla na ku tiya ka mahiselo ya le henhla malapi ya fiberglass, hi kombela u hi tihlanganisa:
