Ungakuthuthukisa Kanjani Ukusebenza Okuphindaphindiwe Kokunamathela Kwe-PTFE High-Temperature Adhesive Tapes

Itheyiphu ye-PTFE yokushisa okuphezulu ivame ukusetshenziswa ezinhlelweni lapho kufanele isuswe futhi isetshenziswe kabusha izikhathi eziningi - kuzitywini zokushisa ngesikhathi sokushintsha, emibhedeni yephrinta ye-3D, noma njengokufihla ubuso kwesikhashana ekuhlanganiseni kogesi. Kodwa-ke, ngemva kwemijikelezo embalwa, amateyipu amaningi ayalahleka, ashiye izinsalela, noma ahluleke ukubopha.

Izindaba ezinhle: ukusebenziseka kabusha kungathuthukiswa kakhulu ngokuthuthukiswa okuhlelekile kuzo zonke izinhlangothi ezine: idizayini enamathelayo , yokwelashwa kwe-substrate , engemuva , kanye nokusebenza okufanele nokugcinwa kahle..

I-Aokai PTFE ithuthukise amateyipu e-PTFE asebenziseka kabusha isebenzisa lezi zimiso. Lo mhlahlandlela uchaza ubukhulu ngamunye ngokuningiliziwe.

I-Adhesive Formulation Optimization - I-Core Factor

I-adhesive ngokwayo iyisinqumo esiyinhloko sokusebenziseka kabusha. Amasu okwakha amane athuthukisa ukusebenza kokunamathela okuphindaphindiwe.

1. Thuthukisa amandla ahlangene kanye nokuminyana kwe-crosslink

Yamukela i-high-polymerization-degree silicone gum futhi ukhulise amasayithi axhumanisayo ukuze uguqule ungqimba olunamathelayo lube oluqinile olunwebekayo. Lokhu kuvimbela ukudabula noma ukudluliswa kwe-adhesive ngesikhathi sokucwecwa okuphindaphindiwe futhi kunciphisa ukulahlekelwa ngokwakho kwesendlalelo seglue. I-adhesive exhunywe kahle icwecwa ngokuhlanzekile kunokuba ihlukaniseke ngaphakathi.

2. Ifomula yokufuduka ye-silicone ephansi

Sebenzisa isistimu yokwelapha ye-platinum-catalyzed bese ususa ngokuphelele izinto ezinesisindo esiphansi. Lokhu kuvimbela ukukhishwa kwamafutha e-silicone e-molecule encane engcolisa indawo yokunamathela futhi igweme ukuncishiswa kwe-viscosity okuqhubekayo. Izinamathiselo ezihamba kancane zigcina i-tack yazo yasekuqaleni emijikelezweni eminingi.

3. Isakhiwo se-Microphase sokunamathela kabusha

Engeza i-MQ silicone resin noma yakha inethiwekhi ye-polymer ehlanganayo ukuze udale ukuhlukaniswa kwe-microphase segment–soft segment separation :

• Izingxenye eziqinile - zinikeza ukubumbana ukumelana nokudluliselwa kweglue esele

• Amasegimenti athambile - ahlinzeka ngobuchule

Ingxenye ye-viscosity ingatholwa ngemva kokusula uthuli ebusweni. Lesi sici 'esingabekwa kabusha' silungele izinhlelo zokusebenza ezidinga ukulungiswa okuningi ngesikhathi sokuhlanganisa.

4. I-adhesive eguquliwe yokugeza ngamanzi ebuyiselekayo

Ngemuva kokuthi indawo enamathelayo isingcoliswe uthuli, le ngcina ye-silicone eguquliwe ingahashazwa ngamanzi ahlanzekile noma i-solvent ethambile, iphinde ithole ngaphezu kuka-90% we-tack yayo yasekuqaleni ngemva kokoma. Lokhu kubaluleke kakhulu ezinhlelweni zokusebenza zegumbi elihlanzekile noma lezogesi lapho ukungcola kungenakugwema.

Qinisa Amandla Okubambelela Phakathi Kwe-PTFE Substrate Nesendlalelo Esinamathelayo

I-PTFE ifaka amandla angaphezulu aphansi kakhulu (18-20 dynes/cm), okubangela kalula ukudluliswa okunamathelayo okugcwele - lonke ungqimba olunamathelayo luphakamisa ukusekelwa - ngaphandle kokwelashwa okuzinikele.

1. Ukwenziwa kusebenze kwe-substrate

Yenza ukufakwa kwamakhemikhali nge-sodium-naphthalene complex noma ukwelashwa kwe-plasma kwindwangu ye-fiberglass ye-PTFE ukwethula amaqembu amhlophe njenge-C=O kanye -OH, okuvumela ukubopha kwamakhemikhali noma ukuhlobana okuqinile kwemishini phakathi kokunamathelayo ne-substrate. Lokhu kuvimbela i-adhesive ekukhipheni i-backing ngesikhathi sokususwa.

2. Okukhethekile primer enamathela

Faka i-primer esebenzayo ngaphambi kokunamathiswa okunamathelayo ukuze wakhe ibhuloho lamakhemikhali phakathi kwe-PTFE ne-adhesive asilicone, uqede ukwehluleka kokunamathisela i-anchoring ngokuphelele. I-primer isebenza njengesixhumanisi samangqamuzana, ebopha kukho kokubili indawo evuliwe ye-PTFE kanye ne-silicone PSA.

I-Aokai PTFE isebenzisa isistimu yokuqala yokuphathelene eqinisekisa ukudluliswa kwe-adhesive eyiziro ekusekelweni ngisho nangemva kwemijikelezo engu-10+ yokususa.

I-Backside (Release Surface) Ukulungiswa Kokwelashwa

Ingemuva le-PTFE liletha ngokwemvelo ukusebenza kokukhululwa, kodwa ukujikajika okuphindaphindiwe nokuhlehlisa kusalimaza indawo enamathelayo ngenxa yokungqubuzana nokudabuka okuncane.

1. Ukukhishwa okuthuthukisiwe kwe-back coating

Faka i-high-crosslink-density fluorosilicone eyengeziwe noma isendlalelo sokukhululwa kwe-silicone ku-PTFE emuva. Igcina amandla azinzile okuqaqa ngaphansi kwezinga lokushisa eliphezulu nokucindezelwa kwesikhathi eside, ivimbela ukudonsa kwefayibha engaphezulu kanye nokulimala kongqimba olunamathelayo ngaphambi kokuphinda lusetshenziswe.

2. Ingemuva eliqoshiwe noma elinesakhiwo esincane

Yehlisa indawo yokuxhumana yangempela phakathi kwesendlalelo sangemuva nendawo enamathelayo, wehlise amandla abhubhisayo asheshayo kuglue ngesikhathi sokuxebuka. Le ndawo ene-micro-textured inciphisa 'i-stick-slip-slip'' engadabula ingcina.

Imihlahlandlela Yokusebenza Nokunakekela

Ngisho nekhasethi eyenziwe kahle kakhulu izohluleka kusenesikhathi uma ingaphathwa kahle. Izinqubo ezifanele zandisa ukusetshenziswa kabusha ngokuphawulekayo.

1. Ukuhlanza okusebenzayo kwendawo yokunamathela

Ukwehla kwe-viscosity kubangelwa kakhulu ukungcoliswa kothuli olungaphezulu. Sula ingaphezulu ngobumnene ohlangothini olulodwa ngendwangu engenalo uthuli ecwiliswe emanzini ahlanzekile noma utshwala obungenamanzi, bese womisa umoya ngokwemvelo noma ngomoya obandayo - ukuqina kuzolulama ngokuphawulekayo. Ukuhlanza okuvamile phakathi kokusetshenziswa kuyisenzo esisodwa esisebenza kahle kakhulu sokulungisa.

2. Gwema umonakalo ngaphansi kwezimo zokusebenza ezimbi kakhulu

• Hlanza kancane nge-engeli encane yokuxebuka (eduze ku-180°) ukuze wehlise izingozi zokwehluleka ukuhlangana.

• Ungasebenzisi izinga lokushisa elilinganiselwe ngaphezulu - i-adhesive izoguga futhi ibe lukhuni, ilahlekelwe ukusebenziseka kabusha.

• Hlanza indawo yokubambelela kusengaphambili - amabala kawoyela angcolisa ngokushesha isendlalelo sokunamathela futhi awakwazi ukususwa ngokugcwele.

3. Khipha amabhamuza omoya ngesikhathi sokucwala

Uthuli luvame ukunqwabelana emaphethelweni ebhamuza futhi lubangele ukugxilisa ingqondo yendawo, kusheshise ukuguga okunamathelayo. Uhlelo olufanele olungenabhamuza (usebenzisa i-squeegee noma i-roller) lwelula ukuphila okusebenziseka kabusha kwetheyiphu.

Isifinyezo - Izilinganiso Ezine Zokuthuthukiswa Kokusebenziseka Kabusha

I-Aokai PTFE ikhiqiza amateyipu e-PTFE alungiselelwe ukunamathela okuphindaphindiwe. Amabanga ethu angawashwa ngamanzi angalulama >90% tack ngemva kokuhlanza, futhi uhlelo lwethu lokuqala luqinisekisa ukudluliswa kokunamathela okuyiziro. Xhumana nathi ukuze uthole izincomo zomkhiqizo kanye nedatha yokuhlola yomjikelezo.
