Uphuculwa njani ukusebenza okuPhindayo kokuncamathela kwe-PTFE iTapes ezincamathelayo zobushushu obuphezulu

Iteyiphu ye-PTFE yobushushu obuphezulu isetyenziswa rhoqo kwizicelo apho kufuneka isuswe kwaye isetyenziswe kwakhona amaxesha amaninzi - kwizitywini zobushushu ngexesha lotshintsho, kwiibhedi zomshicileli we-3D, okanye njengokugquma okwethutyana kwindibano yombane. Nangona kunjalo, emva kwemijikelo embalwa, iiteyiphu ezininzi ziyalahleka, zishiye intsalela, okanye zisilele ekudibaneni.

Iindaba ezimnandi: ukusebenziseka kwakhona kunokuphuculwa kakhulu ngohlaziyo olulungelelanisiweyo kwimilinganiselo emine: ukuncamathelisa , ukwenziwa kwe substrate yonyango , ngasemva uyilo lokutyabeka , kunye nokusebenza ngokufanelekileyo nokugcinwa..

I-Aokai PTFE iphuhlise iiteyiphu zePTFE ezisebenzisekayo kwakhona isebenzisa lemigaqo. Esi sikhokelo sichaza umlinganiselo ngamnye ngokweenkcukacha.

I-Adhesive Formulation Optimization - I-Core Factor

I-adhesive ngokwayo iyona nto iphambili yokumisela ukusetyenziswa kwakhona. Izicwangciso ezine zokuqulunqa ziphucula ukusebenza ngokuphindaphindiweyo ukunamathela.

1. Ukuphucula amandla adibeneyo kunye nokuxinana kwe-crosslink

Yamkela i-silicone ye-high-polymerization-degree-degree gum kwaye wandise iindawo ezinqamlezileyo ukuze ujike umaleko wokuncamathelisa ube sisiqina. Oku kuthintela ukukrazula okanye ukuhanjiswa kwe-adhesive ngexesha lokuhlanjululwa ngokuphindaphindiweyo kunye nokunciphisa ukulahlekelwa kwe-self-out of layer glue. I-adhesive-adhesive-adhesive peels ecocekileyo kunokuba ihlukane ngaphakathi.

2. Ifomula yokufuduka ye-silicone ephantsi

Sebenzisa inkqubo yokunyanga iplatinam-catalyzed uze ususe ngokupheleleyo izinto ezinobunzima obuphantsi. Oku kuthintela ukukhutshwa kweoli ye-silicone encinci ye-molecule engcolisa i-adhesive surface kwaye igweme ukuthotywa kwe-viscosity eqhubekayo. Izincamathelisi zokufuduka ezisezantsi zigcina tack yazo yantlandlolo kwimijikelo emininzi.

3. Isakhiwo se-Microphase sokubambelela kwi-repositionable

Yongeza i-resin ye-silicone ye-MQ okanye wenze inethiwekhi yepolymer edibeneyo ukwenza icandelo elinzima-icandelo elithambileyo lokwahlulahlula i-microphase :

• Amacandelo anzima - ukubonelela ngokubambisana ukuxhathisa ukuhanjiswa kweglue eseleyo

• Iinxalenye ezithambileyo - zibonelela ngobuchule

Inxalenye ye-viscosity inokufunyanwa emva kokusula uthuli phezu komhlaba. Olu 'repositionable' uphawu lufanelekile kusetyenziso olufuna uhlengahlengiso oluninzi ngexesha lendibano.

4. Ukuhlamba ngamanzi ancamathelayo anokufunyanwa kwakhona

Emva kokuba umphezulu wokuncamathelisa ungcoliswe luthuli, le nto yokuncamathelisa ye-silicone eguquliweyo inokuhlanjululwa ngamanzi acocekileyo okanye i-solvent ethambileyo, iphinde ifumane ngaphezulu kwe-90% ye-tack yayo yasekuqaleni emva kokumiswa. Oku kubaluleke kakhulu kumagumbi acocekileyo okanye izicelo zombane apho ungcoliseko lungenakuthintelwa.

Yomeleza i-Anchoring Force phakathi kwe-PTFE Substrate kunye ne-Adhesive Layer

I-PTFE ine-ultra-low surface energy (i-18-20 dynes/cm), eyenza ngokulula ukuhanjiswa kwe-adhesive epheleleyo - yonke i-adhesive layer iphakamisa i-backing - ngaphandle konyango oluzinikeleyo.

1. Ukusebenza komphezulu weSubstrate

Ukuqhuba i-chemical etching kunye ne-sodium-naphthalene complex okanye unyango lwe-plasma kwi-PTFE fiberglass ilaphu ukwazisa amaqela e-polar afana ne-C=O kunye ne-OH, eyenza ukuba i-chemical bonding okanye i-mechanical interlocking eyomeleleyo phakathi kwe-adhesive kunye ne-substrate. Oku kuthintela i-adhesive ukuba ikhuphe i-backing ngexesha lokususwa.

2. Ukwaleka okukhethekileyo kwe-primer

Faka isicelo se-primer esebenzayo ngaphambi kokunamathela kwi-adhesive coating ukwakha ibhulorho yeekhemikhali phakathi kwe-PTFE kunye ne-adhesive silicone, ukuphelisa ukungaphumeleli kwe-anchoring ngokupheleleyo. I-primer isebenza njengekhonkco le-molecular, ukudibanisa kuzo zombini iindawo ezisebenzayo ze-PTFE kunye ne-silicone PSA.

I-Aokai PTFE isebenzisa inkqubo ye-primer yobunikazi eqinisekisa ukuhanjiswa kwe-adhesive kwi-backing nasemva kwe-10+ imijikelo yokususa.

Ngasemva (uKhupho loMphezulu) uLungiso loNyango

I-PTFE ngasemva ihambisa ngokwendalo ukusebenza kokukhululwa, kodwa ukujika-jika okuphindaphindiweyo kunye nokukhulula kuwonakalisa umphezulu wokuncamathelisa ngokukhuhla kunye nokukrazula kancinci.

1. Ukukhutshwa okuphuculweyo kokutyalwa ngasemva

Faka i-high-crosslink-density fluorosilicone okanye umaleko wokukhululwa we-silicone kwi-PTFE ngasemva. Igcina amandla azinzileyo angaphumliyo phantsi kobushushu obuphezulu kunye nokunyanzeliswa kwexesha elide, ukuthintela ukutsalwa komphezulu wefiber kunye nomonakalo kumaleko wokuncamathelisa ngaphambi kokusetyenziswa kwakhona.

2. Embossed okanye micro-structured ngasemva

Nciphisa indawo yokudibanisa yokwenene phakathi komqolo ongemva kunye nomgangatho wokubambelela, unciphisa ngokukhawuleza amandla atshabalalisayo kwiglue ngexesha lokucoca. Lo mphezulu we-micro-textured unciphisa 'i-stick-slip-slip' enokuthi ikrazule into yokuncamathelisa.

IziKhokelo zokuSebenza kunye noLondolozo

Neyona tape eyenziwe kakuhle kakhulu iya kusilela kwangoko ukuba ingaphathwa kakuhle. Iinkqubo ezifanelekileyo zandisa ukusetyenziswa kwakhona ngokubonakalayo.

1. Ukucoca okusebenzayo kwendawo yokubambelela

Ukwehla kweViscosity kubangelwa ikakhulu kukungcoliseka kothuli olungaphezulu. Sula umphezulu ngobunono kwicala elinye ngelaphu elingenathuli lifakwe emanzini acocekileyo okanye utywala obuyi-anhydrous, emva koko wome ngomoya ngokwemvelo okanye ngomoya obandayo-ubuchule buya kubuyiselwa ngokuphawulekayo. Ukucoca rhoqo phakathi kokusetyenziswa yeyona nto isebenzayo yolondolozo.

2. Gwema umonakalo phantsi kweemeko zokusebenza ezigqithisileyo

• I-peel ngokukhawuleza kwi-angle encinci ye-peeling (kufuphi ne-180 °) ukunciphisa umngcipheko wokungaphumeleli kokubambisana.

• Ungasebenzisi ngaphezu kweqondo lokushisa elilinganisiweyo - i-adhesive iya kuguga kwaye ibe nzima, ilahlekelwe ukuphinda isetyenziswe.

• Coca indawo yokubambelela kwangaphambili - amabala e-oyile angcolisa ngokukhawuleza i-adhesive layer kwaye ayikwazi ukususwa ngokupheleleyo.

3. Ukuphelisa amaqamza omoya ngexesha lamination

Uthuli ludla ngokuqokelelana ngasemiphethweni yeqamza kwaye lubangele uxinzelelo lwendawo, lukhawulezisa ukuguga okuncamathelayo. Usetyenziso olufanelekileyo lwe-bubble-free (usebenzisa i-squeegee okanye i-roller) yandisa ubomi obunokuphinda busebenziseke kwiteyiphu.

Isishwankathelo - Imilinganiselo emine yoPhuculo lokuSebenzisa kwakhona

I-Aokai PTFE yenza iiteyiphu ze-PTFE ezilungiselelwe ukuncamathela okuphindaphindiweyo. Amabakala ethu ahlanjwa ngamanzi anokubuyisela> i-90% tack emva kokucoca, kwaye inkqubo yethu ye-primer iqinisekisa ukuhanjiswa kwe-adhesive zero. Qhagamshelana nathi ngeengcebiso zemveliso kunye nedatha yovavanyo lomjikelo.
