Ubushushu kunye neViscosity Attenuation yePTFE High-Temperature Tape

I-Jiangsu Aokai New Materials, umenzi oqeqeshiweyo we-PTFE high-temperature tape, ichaza utshintsho lwentsebenzo ye-PTFE tape emva kokusetyenziswa kwe-oven ngokuphindaphindiweyo.Ukunciphisa ukuxhatshazwa kweqondo lokushisa kunye nokubamba i-viscosity ikakhulu kulele kwi- adhesive layer , kunokuba i-PTFE substrate. Ubume bemolekyuli ye-PTFE substrate izinzile ngokugqithisileyo kwaye ayinabudala bungaphantsi kwama-260°C. Ngokwahlukileyo, iileya zokubambelela ezinobushushu obuphezulu ezifana ne-silicone ziguga kwi-thermo-oxidative phantsi kokufudumeza okuphindaphindiweyo, ekugqibeleni kugqiba ubomi benkonzo ye-PTFE tape yobushushu obuphezulu.

1. UMthetho Wokuthomalalisa wokuxhathisa ubushushu

Iqondo lokushisa eliqhelekileyo le-oven (≤ 260 ° C) I-adhesive iguga ngokucothayo nangokuqhubekayo, kunye nokumelana nokushisa okuqhelekileyo kuncipha unyaka nonyaka. Ubomi bayo benkonzo yexesha elide malunga neminyaka eyi-1-3.

Iqondo lokushisa elincinci (260-300 ° C) Ukuguga okunamathelayo kukhawuleza ngokukhawuleza, kwaye ubomi benkonzo buhla kakhulu ukusuka kwiminyaka emininzi ukuya kwiiveki ezimbalwa kuphela.

Ubushushu obugqithisileyo (＞300°C) Incamathelisa iyathamba, ibole kwaye ide ikhuphe ikharbhoni ngokukhawuleza, okukhokelela ekulahlekeni kwe-viscosity ekhawulezileyo kunye nokuxobuka ngexesha elifutshane.

Ukuphinda-phindwa kwebhayisekile yobushushu Ukufudumeza okukhawulezileyo kunye nokupholisa kuvelisa impembelelo yoxinzelelo lwe-thermal, ebangela i-micro-delamination phakathi kwe-adhesive kunye ne-substrate, kunye nokukhawulezisa ukusilela kokumelana nobushushu.

2. UMthetho Wokuthomalalisa wokubamba iViscosity

Ukwehla okucothayo phantsi kweemeko eziqhelekileyo zokusebenza Ngaphakathi koluhlu olulinganisiweyo lobushushu, i-viscosity yokubamba iyancipha ngokuthe ngcembe ngokunyuka kwemijikelo ye-oveni, kwaye umaleko wokuncamathelisa uba lukhuni kwaye ubhinqe ngokuhamba kwexesha.

Ukuthomalalisa okubukhali phantsi kobushushu obugqithisileyo kunye neemeko ezirhabaxa Xa sele kushushu kakhulu okanye kuvezwe kumajelo eendaba ekhemikhali, amandla okubopha angehla ngaphezu kwe-50% emva kokupholisa.

Inqaku elibalulekileyo lokungaphumeleli kokusebenza Nangona i-tape ihlala ibonakala, i-non-stick kunye neempawu zokubamba zingaphumeleli kwangaphambili, zifuna ukutshintshwa ngexesha elifanelekileyo.

3. Imiba ephambili ekhawulezisa ukuthotywa koMsebenzi

Uhlobo lwe-adhesive Silicone i-adhesive i-adhesive pressure-sensitive adhesive i-adhesive resistance to 260 ° C, iphezulu kakhulu kune-adhesive ye-acrylic (kuphela i-120-150 ° C).

Ulwakhiwo lwe-Substrate Iteyiphu ye-Fiberglass eyomeleziweyo ye-PTFE inikezela uzinzo olubalaseleyo lwe-dimensional kunye nokumelana nokunyuka kwe-thermal, kunye nobomi benkonzo obude kune tape yefilimu ye-PTFE esulungekileyo.

Indawo yokusebenza I-Friction ngexesha lokusebenza kwe-oven, kunye nokuqhagamshelana ne-solvents okanye i-flux, iya kwandisa ukuthotywa komzimba kunye neekhemikhali.

Umgangatho weMaterial Iiteyiphu ezikumgangatho ophantsi zihlala ziphawulwa ngokuxokayo ukumelana nobushushu, ubudala ngokukhawuleza kwaye ziyasilela emva kwemijikelo embalwa ye-oveni kuphela.

4. IiNgcebiso zokuSetyenziswa ukuze kuthotywe ukuthotywa

Ukulawula ubushushu obungqongqo Gcina ubushushu bexesha elide obuqhubekayo bokusebenza ngaphantsi kwe-260 ° C kwaye ugweme ukusebenza ngokugqithisileyo kobushushu.

Ukukhetha imodeli enengqiqo Khetha i-tape ye-silicone esekelwe kwi-PTFE ephezulu, enokumelana nemijikelo engaphezu kwama-500 kwi-SMT kunye neenkqubo ezifanayo.

Ukusetyenziswa okusemgangathweni Coca ngokucokisekileyo umphezulu wokudityaniswa nge-ethanol epheleleyo phambi kokuba i-lamination iqinisekise ukuxinezeleka okufanayo kunye nokufaneleka okuqinileyo.

Ukulungiswa kwenkqubo Nciphisa ukuxhaphaka okungeyomfuneko kwe-thermal ukunciphisa umonakalo woxinzelelo lwe-thermal kwi-adhesive layer.

Ukugcinwa okufanelekileyo Gcina i-tape engasetyenziswanga kwindawo evaliweyo, emnyama, epholileyo kunye neyomileyo ukukhusela ukuguga kwangaphambili kwe-adhesive.

Ukutshintshwa kwangexesha Ukutshintshwa ngokukhawuleza kuyafuneka xa uqweqwe lwe-coating, i-carbonization yomhlaba, i-edge warping okanye ilahleko yentsebenzo engekho intonga eyenzekayo, ukwenzela ukuba kuqinisekiswe imveliso ezinzileyo.

Lo mxholo ungasentla unikwe nguJiangsu Aokai New Material Technology Co., Ltd.

Ukuba ufuna iiparameters ezineenkcukacha, iimeko zesicelo kunye nezisombululo ezilungiselelwe umgca wethu wemveliso opheleleyo kuquka i-PTFE amalaphu obushushu obuphezulu, iiteyiphu ze-PTFE zobushushu obuphezulu, amabhanti e-mesh anobushushu obuphezulu be-PTFE, amabhanti e-fuser angenamthungo, ilaphu le-PTFE elisecaleni elinye, i-high-temperature-high-temperature resistant , kunye ne-high-high-temperature resistant conveyor, kunye ne-fiberglass enganyangekiyo, kunye ne-high-high-temperature resistant ;
