Ku hunguta mahiselo & Viscosity ya PTFE ya Thepi ya Mahiselo ya le Henhla

Jiangsu Aokai New Materials, muendli wa xiphurofexinali wa PTFE high-temperature tape, u hlamusela ku cinca ka matirhelo ya PTFE tape endzhaku ko phindha-phindha ku tirhisiwa ka oven.The attenuation of temperature resistance and holding viscosity mainly lies in the adhesive layer , ku tlula substrate ya PTFE. Xivumbeko xa molecular xa PTFE substrate xitshamisekile swinene naswona axi dyuharile swinene ehansi ka 260°C. Kuhambana na sweswo, ti layers ta adhesive ta mahiselo yale henhla tofana na silicone ti hundza eka thermo-oxidative aging ehansi ka ku hisiwa loku phindha-phindhiweke, leswi ekuheteleleni swi vekaka vutomi bya ntirho wa PTFE high-temperature tape.

1. Nawu wa Attenuation wa ku Tiyisela hi Mahiselo

Mahiselo ya ntolovelo ya oven (≤ 260°C) Xinamarheti xi dyuhala hiku nonoka naswona hiku famba ka nkarhi, laha ku tiya ka mahiselo ya vito swihungutekaka lembe na lembe. Vutomi bya yona bya nkarhi wo leha bya ntirho byi kwalomu ka 1–3 wa malembe.

Ku hisa loku tlulaka nyana (260–300°C) Ku dyuhala ka adhesive swi hatlisa swinene, naswona vutomi bya vutirheli byi hunguteka swinene kusuka eka malembe yo hlaya kuya eka mavhiki nyana ntsena.

Ku hisa lokukulu swinene (>300°C) Xinamarheti xa olova, xa bola hambi kuri ku carbonize hiku hatlisa, leswi endlaka leswaku ku lahlekeriwa hi viscosity hiku hatlisa xikan’we naku rhurhumela hi nkarhi wo koma.

Ku phindha-phindha ku rhendzeleka ka mahiselo Ku hisa ka xihatla na ku kufumela nkarhi na nkarhi swi humesa ku khumbeka ka ntshikelelo wa mahiselo, leswi vangaka micro-delamination exikarhi ka adhesive na substrate, naswona swi hatlisisa ku tsandzeka ka ku tiya ka mahiselo.

2. Nawu wa Attenuation wa ku Khoma Viscosity

Kuhunguteka hiku nonoka ehansi ka swiyimo swa ntolovelo swa ntirho Endzeni ka mpimo wa mahiselo lawa ya ringanyetiweke, viscosity yo khoma yihunguteka hakatsongotsongo loko ku tlakuka ka swirhendzevutani swa oven, naswona leyara yo namarhela yi tiya naswona yi tshoveka hiku famba ka nkarhi.

Sharp attenuation ehansi ka mahiselo yo tlula mpimo na swiyimo swo tika Loko se yi hise ngopfu kumbe yi hlangana na ti chemical media, matimba ya bonding yanga hunguteka kutlula 50% endzhaku ko titimela.

Nhlayo ya nkoka ya ku tsandzeka ka ntirho Hambi loko thepi yi tshama yi nga onhakanga hi ku languteka, swivumbeko swa yona leswi nga namarheliki na ku khoma swi nga ha tsandzeka ka ha ri emahlweni, leswi lavaka ku cinciwa hi nkarhi.

3. Swilo swa nkoka leswi hatlisisaka ku hohloka ka Matirhelo

Muxaka wa adhesive Silicone pressure-sensitive adhesive yina ku tiya ka mahiselo kuya fika eka 260°C, leswi tlakukeke swinene kutlula acrylic adhesive (120–150°C ntsena).

Xivumbeko xa substrate Thepi ya PTFE leyi tiyisisiweke hi fiberglass yi tisa ku tshamiseka ka kahle swinene ka dimensional na ku lwisana na thermal creep, na vutomi byo leha swinene bya vutirheli ku tlula thepi ya filimi ya PTFE yo basa.

Ndzhawu yo tirhela eka yona Ku hlangana hinkarhi wa ntirho wa oven, xikan’we naku khumbana na ti solvents kumbe flux, swita nyanyisa ku onhaka ka physical na ti khemikhali.

Khwalithi ya swilo Tithepi ta khwalithi yale hansi titala kuva na ku tiya ka mahiselo loku funghiweke hi mavunwa, ti dyuhala hiku hatlisa naswona ti tsandzeka endzhaku ka swirhendzevutani swintsongo ntsena swa oven.

4. Switsundzuxo swa Matirhiselo ku hunguta ku onhaka

Ku lawula mahiselo hi ndlela yo tika Hlayisa mahiselo ya nkarhi woleha lawa ya yaka emahlweni ya ntirho ehansi ka 260°C naswona papalata ku tirha hi mahiselo yo tlula mpimo.

Ku hlawuriwa ka modele loku twalaka Hlawula thepi ya PTFE ya xiyimo xa le henhla leyi simekiweke eka silicone, leyi nga tiyiselaka ku tlula 500 wa swirhendzevutani eka SMT na maendlelo yo fana.

Ku tirhisiwa loku ringaniseriweke Hlantswa kahle bonding surface hi absolute ethanol loko kungase lamination kutiyisisa ntshikelelo lowu fanaka xikan’we naku ringanela swinene.

Ku antswisiwa ka maendlelo Pfuxeta frequency ya thermal shock leyinga lavekiki ku hunguta ku onhaka ka thermal stress eka adhesive layer.

Ku hlayisa kahle Hlayisa thepi leyinga tirhisiwangiki eka ndzhawu leyi pfaleriweke, ya munyama, yo kufumela naku oma ku sivela ku dyuhala ka xinamarheti ka ha ri na nkarhi.

Ku cinciwa hi nkarhi Ku cinciwa ka xihatla swa laveka loko ku tshoveka ka coating, surface carbonization, edge warping kumbe ku lahlekeriwa hi matirhelo ya non-stick swihumelela, leswaku kuta tiyisisiwa vuhumelerisi lebyi tiyeke.

Leswi nga laha henhla swi nyikiwile hi Jiangsu Aokai New Material Technology Co., Ltd.

Loko u lava tipharamitha ta vuxokoxoko, swiyimo swa xikombelo na swintshuxo leswi endleriweke layini ya hina ya swikumiwa leswi heleleke ku katsa na malapi ya mahiselo ya le henhla ya PTFE, tithepi ta mahiselo ya le henhla ya PTFE, mabandhi ya mesh ya mahiselo ya le henhla ya PTFE, mabandhi ya fuser lama nga riki na swirhabyani, lapi ra PTFE ra tlhelo rin’we, mabandhi ya conveyor lama lwisanaka na mahiselo ya le henhla na lapi ra fiberglass leri tiyiselaka mahiselo ya le henhla, hi kombela u ntshunxeka ku hi tihlanganisa:

Minkarhi hinkwayo hi namarhela filosofi ya vutshila na vutshembeki, naswona hi ku nyika swintshuxo swa indasitiri leswi tshembekaka swa xiyimo xin’we na vukorhokeri byo tekela enhlokweni.
