Engeri y'okulongoosaamu enkola y'okunyweza enfunda eziwera mu PTFE High-Temperature Adhesive Tapes

PTFE high-temperature tape etera okukozesebwa mu nkola nga erina okuggyibwawo n’okuddamu okusiigibwa emirundi mingi – ku heat sealers mu kiseera ky’okukyusa, ku 3D printer beds, oba nga temporary masking mu electronics assembly. Kyokka oluvannyuma lw’okutambula emirundi mitono, obutambi bungi bufiirwa tack, ne bulekawo ebisigadde oba okulemererwa okukwatagana.

Amawulire amalungi: okuddamu okukozesebwa kuyinza okulongoosebwa ennyo okuyita mu kulongoosa okukwasaganyizibwa mu bipimo bina: adhesive formulation , substrate treatment , backside coating design , n’okukola obulungi & okuddaabiriza.

Aokai PTFE ekoze obutambi bwa PTFE obusobola okuddamu okukozesebwa nga ekozesa emisingi gino. Ekitabo kino kinnyonnyola buli kitundu mu bujjuvu.

Okulongoosa mu nkola y’okusiiga – Ensonga enkulu

Ekyesiiga kyennyini kye kisinga okusalawo okuddamu okukozesebwa. Enkola nnya ez’okukola okulongoosa enkola y’okunyweza enfunda eziwera.

1. Okulongoosa amaanyi g’okukwatagana n’obuzito bw’okusalasala

Wettanira ggaamu ya silikoni eya diguli ya polimeeri eya waggulu era yongera ku bifo ebisalasala okufuula oluwuzi olusiiga okufuuka ekikalu ekiwanvuwa. Kino kiziyiza okukutuka oba okukyusa ekyesiiga mu kiseera ky’okusekula enfunda eziwera era kikendeeza ku kwefiirwa kw’oluwuzi lwa kalaamu. Ekisiiga ekikwatagana obulungi kisekula bulungi okusinga okwawukana munda.

2. Enkola y’okusenguka kwa silikoni entono

Kozesa enkola ya platinum-catalyzed addition curing system era oggye bulungi ebintu ebizitowa molekyu entono. Kino kiziyiza okufuluma kw’amafuta ga silikoni aga molekyu entono agacaafuwaza kungulu eyeesiiga era ne kyewala okukendeera kw’obuzito obutasalako. Ebisiiga ebitasenguka nnyo bikuuma tack yabyo eyasooka okumala enzirukanya nnyingi.

3. Ensengekera ya microphase okusobola okuddamu okukwatagana

Okwongerako MQ silicone resin oba okukola omukutu gwa polimeeri oguyingira wakati okukola hard segment–soft segment microphase separation :

• Ebitundu ebikalu – biwa okukwatagana okuziyiza okutambuza kwa kalaamu okusigaddewo

• Ebitundu ebigonvu – biwa tackiness

Ekitundu ky’obuzito (viscosity) kisobola okuddizibwa oluvannyuma lw’okusiimuula enfuufu ku ngulu. Engeri eno eya 'repositionable' nnungi nnyo ku nkola ezeetaaga okutereeza emirundi mingi mu kiseera ky'okukuŋŋaanya.

4. Amazzi-okunaaba recoverable modified adhesive

Oluvannyuma lw’okusiiga enfuufu, ekyesiiga kino ekya silikoni ekikyusiddwa kiyinza okunaazibwa n’amazzi amayonjo oba ekizimbulukusa ekitono, ne kiddamu okufuna ebitundu ebisukka mu 90% ku tack yaakyo eyasooka oluvannyuma lw’okukala. Kino kya mugaso nnyo mu bifo ebiyonjo oba ebyuma ebikozesebwa mu byuma bikalimagezi nga obucaafu tekwewalika.

Okunyweza Amaanyi g’okusiba Wakati wa PTFE Substrate ne Adhesive Layer

PTFE erimu amaanyi amatono ennyo ku ngulu (18-20 dynes/cm), nga kino kyangu okuleeta okukyusa ekyesiiga mu bujjuvu – oluwuzi lwonna olw’okusiiga lusituka okuva ku mugongo – awatali kujjanjaba kwetongodde.

1. Okukola kw’okungulu kwa substrate

Kola eddagala eriyitibwa chemical etching ne sodium-naphthalene complex oba plasma treatment ku PTFE fiberglass fabric okuyingiza ebibinja by’enjuba nga C=O ne -OH, okusobozesa okukwatagana kw’eddagala oba okuyungibwa okw’amaanyi okw’ebyuma wakati w’ekyesiiga ne substrate. Kino kiremesa ekyesiiga okusekula ku mugongo nga bakiggyamu.

2. Okusiiga kwa primer mu ngeri ey’enjawulo

Siiga reactive primer nga tonnaba kusiiga adhesive okuzimba omutala gw’eddagala wakati wa PTFE ne silicone adhesive, okumalawo ddala okulemererwa kw’okusiba. Primer ekola nga molekyu link, nga ekwatagana ku byombi activated PTFE surface ne silicone PSA.

Aokai PTFE ekozesa enkola ya primer ey’obwannannyini ekakasa nti zero adhesive transfer ku backing ne bwe wabaawo 10+ removal cycles.

Okulongoosa mu bujjanjabi obw’emabega (Release Surface).

PTFE emabega mu butonde etuwa omulimu gw’okufulumya, naye okuzingulula n’okusumulula enfunda eziwera bakyayonoona kungulu kwesiiga okuyita mu kusikagana n’okukutula micro-tearing.

1. Enhanced release performance emabega okusiiga

Siiga ey’enjawulo eya crosslink-density enkulu layeri ya fluorosilicone oba silicone release layer ku mugongo gwa PTFE. Ekuuma amaanyi ag’okusumulula aganywevu wansi w’ebbugumu eringi n’okunyigirizibwa okumala ebbanga eddene, okuziyiza okusika kw’obuwuzi obw’okungulu n’okwonooneka kw’oluwuzi olusiiga nga tennaddamu kukozesebwa.

2. Omugongo oguliko embossed oba micro-structured

Kendeeza ku kifo kyennyini ekikwatagana wakati w’oluwuzi lw’emabega n’oludda olusiiga, n’okendeeza ku maanyi ag’okusaanyaawo ag’amangu ku kalaamu ng’osekula. Kino micro-textured surface kikendeeza ku 'stick-slip' effect eyinza okukutuka adhesive.

Enkola y’emirimu n’okuddaabiriza

Ne ttaapu esinga okukola yinginiya ejja kulemererwa nga bukyali singa ekwatibwa bubi. Enkola entuufu egaziya nnyo okuddamu okukozesebwa.

1. Okuyonja mu ngeri ey’amaanyi ku ngulu w’ekyesiiga

Okukendeera kw’obuzito (viscosity decline) kusinga kuva ku bucaafu bw’enfuufu ey’okungulu. Siimuula mpola kungulu mu ludda olumu n’olugoye olutaliimu nfuufu olunnyikiddwa mu mazzi amayonjo oba omwenge ogutaliimu mazzi, olwo okalize mu mpewo mu butonde oba n’empewo ennyogovu – tackiness ejja kudda engulu mu ngeri eyeewuunyisa. Okwoza buli kiseera wakati w’okukozesa kye kikolwa ekimu ekisinga okukola obulungi mu ndabirira.

2. Weewale okwonooneka mu mbeera y’okukola ennyo

• Sekula mpola ku nkoona entono ey’okusekula (okumpi ne 180°) okukendeeza ku bulabe bw’okulemererwa kw’okukwatagana.

• Tokozesa bbugumu erisukka erigereddwa – ekyesiiga kijja kukaddiwa era kikalube, kifiire okuddamu okukozesebwa.

• Okwoza ekifo ekinyweza nga bukyali – amabala g’amafuta gacaafuwa mangu oluwuzi olusiiga era tegasobola kuggyibwawo mu bujjuvu.

3. Ggyawo ebiwujjo by’empewo mu kiseera ky’okukola lamination

Enfuufu etera okukuŋŋaanyizibwa okwetooloola empenda z’ebiwujjo era ne kivaako okusengejja situleesi mu kitundu, okwanguya okukaddiwa kw’ebyesiiga. Okusiiga obulungi nga tolina bubble (nga okozesa squeegee oba roller) kyongera ku bulamu bwa tape okuddamu okukozesebwa.

Mu bufunze – Ebipimo bina eby’okulongoosa mu kuddamu okukozesebwa

Aokai PTFE ekola obutambi bwa PTFE obulongooseddwa okusobola okunywerera enfunda eziwera. Grades zaffe ezinaaba mu mazzi zisobola okuddamu >90% tack oluvannyuma lw’okuyonja, era enkola yaffe eya primer ekakasa zero adhesive transfer. Tukwasaganye okufuna ebiteeso by’ebintu n’ebikwata ku kugezesa enzirukanya.

Ekiwandiiko kino eky’ekikugu kiweereddwa... Jiangsu Aokai Ebintu Ebipya Tekinologiya Co., Ltd.

Bw’oba oyagala okuyiga ebikwata ku nsonga enzijuvu, embeera z’okukozesa n’ebigonjoola ebikoleddwa ku mutindo gw’ebintu byaffe ebijjuvu, omuli emifaliso egy’ebbugumu erya waggulu erya PTFE, obutambi obusiiga obwa PTFE obw’ebbugumu eringi, emisipi egy’ekyuma ekitambuza eby’akatimba egya PTFE, emisipi egy’ekyuma ekifuyira ezitaliiko musonno, olugoye olusiigiddwako PTFE olw’oludda olumu, emisipi egy’okutambuza egigumira ebbugumu ne fiberglass ey’ebbugumu eringi emifaliso, tukusaba otuukirire ng'oyita ku mikutu gino wammanga:
