Tanihi muendli wa xihlovo xa xiphurofexinali wa PTFE thepi yo namarhela na switirhisiwa leswi fambelanaka na swona, Jiangsu Aokai New Materials Technology Co., Ltd. yi andlala vutivi lebyi faneleke. For PTFE high-temperature tapes , ku hlawuriwa ka maphepha yo humesa na ti substrates ta filimi yo humesa na switirhisiwa swo humesa i nchumu wa nkoka lowu vekaka mpimo wa le hansi wa mbuyelo wo humesa na mpimo wa le henhla wa ku tshamiseka ka vuhlayiselo.
Ku twisisa minkucetelo leyi swi pfuna vaendli na vatirhisi ku hlawula liner yo humesa leyi faneleke eka swilaveko swa vona swo karhi swa matirhiselo.
Ndlela leyi Tisubstrates to hambana ti khumbaka ha yona matirhelo ya Thepi ya PTFE
Tanihi murhwali wa xifunengeto xo humesa, swivumbeko swa physical na ti khemikhali ta ti substrates swi veka ku tiya ka morphological ka switirhisiwa swo humesa hi nkarhi wa ku hlayisiwa na ku cheriwa.
1. Xiphemu xa le hansi xa PET (Polyester Film).
Ku tshamiseka ka Vuhlayiselo: Swi kahle swinene. PET yi hlayisa xivumbeko lexi tiyeke na swipimelo eka ndzhawu yo anama ya mahiselo. Yi na ku nga tirhi lokukulu ka tikhemikhali, ku hava ku onhaka hikwalaho ka ku amukeriwa ka ndzhongho kumbe ku angula na swinamarheti, ku hava ku khuluka ka tifibre, na ku basa lokukulu.
Matirhelo ya Ntshunxeko: Ya tshamisekile naswona ya lawuriwa. Vuandlalo bya yona lebyi nga ni xiphepherhele, lebyi tsindziyeleke byi endla leswaku ku va ni swiyimo leswinene swa ku peta hi ku kongoma swilo leswi humesaka swilo. Kambe hikokwalaho ka swivumbeko swa yona swale henhla swa michini, yinga humesa mpfumawulo wo peeling ehansi ka swiyimo swa rivilo lerikulu kumbe high-peeling-force.
2. Xitirhisiwa xa Phepha ra Kraft
Ku tshamiseka ka Vuhlayiselo: Swiphiqo leswi nga erivaleni. Ku tiya ka mahiselo yale henhla hi xitalo swile hansi ka 150°C. Kutala kuva na deformation leyi vangiwaka hi ndzhongho xikan’we naku dyuhala ka brittleness endzhaku ka ku hlayisiwa ka nkarhi woleha. Tifibre ta maphepha leti waka ti nga ha thyakisa swilo leswi namarhelaka naswona ti hunguta ku basa.
Matirhelo ya ku Humesiwa: Swi titshege ngopfu hi thekinoloji yo peta. Vuandlalo byosungula bya rough byi lava vutshunguri byo engetela bya coating (film coating, clay coating) kuva yifikeleriwa ku olova; handle ka sweswo, matimba yo humesa lama nga ringaniki ma nga humelela.
Eka matirhelo yo hundzula thepi ya xiothomethi ya vholumo yale henhla, ku hlawula exikarhi ka PET na phepha ra kraft swi khumba swinene vukorhokeri bya vuhumelerisi. Ti films to humesa PET tinyika kutshamiseka ka dimensional yale henhla, ku hlayisa ku anama loku nga cincekiki na ku leha hambi kuri ehansi ka ndzhongho wohambana hambana – swa nkoka swinene eka rotary die-cutting xikan’we na high-speed slitting laha ku lavekaka ku tiyisela ka ±0.5mm. Kraft paper, hambi leswi yinga durhiki ngopfu, yinga ndlandlamuxa kumbe ku hunguteka hi 1-2% loko ku cinca ka ndzhongho, leswi yisaka eka misalignment eka switirhisiwa swa precision. Eka ti PTFE tapes leti hlayisiweke kutlula 12 wa tinhweti, ti PET-based release liners ti kombisa ku cinca ka dimensional yale hansi ka 0.1%, laha kraft paper yinga kombisa ku curling loku vonakaka kumbe edge lifting endzhaku ka 6 wa tinhweti eka ti warehouses letinga lawuriwiki hi maxelo. Eka switirhisiwa leswi lavaka ku cheriwa ka thepi ya flat hiku hetiseka (xikombiso, eka ti platens leti hisiweke kumbe ti sealing bars), PET substrate ya hlohleteriwa swinene.
Ndlela Leyi Switirhisiwa swo Humesa (Silicone vs. Fluorinated) swi khumbaka Matirhelo ya Thepi ya PTFE
Interacting with the silicone pressure-sensitive adhesive on PTFE adhesive tape , switirhisiwa swo humesa i swa nkoka eka matirhelo ya ku rhurhumela na ku tshembheka ka vukorhokeri bya nkarhi wo leha.
1. Xitirhisiwa xo Humesa Silicone
Kutshamiseka ka vuhlayiselo: Khombo ra ku rhurha ka silicone rikona kambe ringa antswisiwa hiku tirhisa formula optimization. Swiphemu swa molekhuli swinga rhurhela eka swiphemu leswi namarhelaka ehansi ka mahiselo yale henhla kumbe ntshikelelo wa nkarhi woleha, leswi endlaka leswaku kuva na matimba yo humesa lawa ya engetelekeke hambi kuri masalela ya namarheta. Khombo leri ri nga hungutiwa swinene hi ku amukela tifomula ta crosslink density yale henhla na low-migration.
Matirhelo ya Ntshunxeko: Ku fambisana kahle na ntsengo wo ringanela. Swi funengeta nxaxamelo wo anama wa matimba yo humesa lama lulamisiwaka. Hambiswiritano, havumbirhi bya release agent na PTFE tape swi wela eka ti silicone-based systems, leswi tisaka khombo ra ku n’oka ka xiphemu lexi fanaka – leswi yisaka eka ku tika ku peeling (heavy release).
2. Xiaki xo Humesa lexi nga ni fluorine
Kutshamiseka ka Vuhlayiselo: Ku tsandzeka ka ti khemikhali tale henhla xikan’we naku tshamiseka lokunene hiku angarhela. Eneji yale hansi yale henhla xikan’we na swivumbeko swa tikhemikhali leswi tiyeke swinene – swinga rhurhela ngopfu eka ti layers leti namarhelaka. Yi hlayisa matimba yo humesa lawa ya tiyeke kuringana nkarhi woleha na ku tiya loku hlamarisaka eka mahiselo yale henhla xikan’we na ndzhongho wale henhla.
Matirhelo ya ku Humesa: Vuyelo bya le henhla na lebyi tiyeke byo ntshunxa. Hi eneji yale hansi swinene yale henhla, yinyika matimba yo olova no tshamiseka yo humesa kutlula switirhisiwa swo humesa silicone – leswi endlaka leswaku kuva na ku olova, kungari na mpfumawulo, naswona kungari na masalela. Yikombisa ku antswa ka tikhemikhali inertness kuya eka silicone pressure-sensitive adhesives naswona yi papalata hiku hetiseka timhaka to tika ta ku humesiwa.
Nkatsakanyo – Nkatsakanyo lowunene wa Thepi ya Mahiselo ya le Henhla ya PTFE
Hiku angarhela, ku hlanganisiwa ka PET substrate + fluorinated release agent i xitshunxo lexinene lexi kumekaka namuntlha, lexi ringaniselaka hi ku hetiseka ku tshamiseka ka vuhlayiselo bya kahle swinene na mbuyelo lowunene wo humesa.

Ntshunxa ntirho wa nkoka
Xitirhisiwa xo humesa fluorine > Xitirhisiwa xo humesa silicone
Ku rhangisa ku tshamiseka ka vuhlayiselo
Xitirhisiwa xa PET > Xitirhisiwa xa phepha ra kraft
Xikimi xo fambelanisa lexi ringanyetiweke: PET substrate leyingana fluorinated release agent i nhlawulo wa xiyimo xale henhla. Ku tiya ka yona lokukulu ka mahiselo xikan’we naku tiya ka dimensional, swihlanganisiwe na swipfuno swa inertness ya ti khemikhali ta switirhisiwa swo humesa fluorinated, switiyisisa hiku hetiseka matirhelo ya zero-residue peeling xikan’we naku tshamiseka ka nkarhi woleha wa vuhlayiselo bya PTFE adhesive tape.
Mahetelelo – Hlawula Release Liner ya wena hi ku ya hi Swilaveko swa Xikombelo
Eka vaendli na vatirhisi va PTFE high-temperature tape , ku twisisa ku cinca-cinca exikarhi ka swihlawulekisi swa substrate na release agent swi endla leswaku ku va na swiboho leswi nga na vutivi. Loko PET + fluorinated yiyimela xitshunxo xa premium, kraft paper + silicone ya xiyimo xale henhla yitshama yiri ndlela leyi tirhaka eka switirhisiwa swa vuhlayiselo leswinga durhiki, swa nkarhi wo koma.
As a trusted PTFE adhesive tape manufacturer , Aokai yi nyika swintshuxo leswi endleriweke ku humesa liner ku tsemakanya layini ya hina ya swikumiwa leswi heleleke – PTFE leyi pfanganisiweke na lapi, PTFE conveyor belt, PTFE mesh belt, PTFE film tape, na PTFE fiberglass tape.
Leswi nga laha henhla swi nyikiwile hi Jiangsu Aokai New Materials Technology Co., Ltd.
Loko u lava vuxokoxoko bya swihlawulekisi, swintshuxo swa xikombelo, na vukorhokeri lebyi endleriweke layini ya hina leyi heleleke ya swikumiwa ku katsa na lapi ra mahiselo ya le henhla ya PTFE, thepi ya mahiselo ya le henhla ya PTFE, bandhi ra mesh ra PTFE, bandi ra muchini ro fusa leri nga na swirhabyani, lapi ra PTFE ra tlhelo rin’we, bandi ro fambisa leri lwisanaka na mahiselo ya le henhla na lapi ra fiberglass leri tiyiselaka ku hisa , hi kombela u ntshunxeka ku hi tihlanganisa:
Hi namarhela vutshila na vutshembeki, hi tinyiketerile ku nyika swintshuxo leswi tshembekaka swa xiyimo xin’we na vukorhokeri byo tekela enhlokweni eka vaxavi hinkwavo.
