Engeri Fiberglass Thermal Shrinkage gye ekosa PTFE Tape Dimensional Stability

OMU PTFE tape ekendeera, ekulukuta, oba ewunyiriza nga ekozesebwa, etera okulemererwa mu nnimiro. Ekikolo ekivaako kitera okudda emabega ku kigerageranyo kimu: omutindo gw’okukendeera kw’ebbugumu okw’ekisengejjero kya fiberglass.

Mu kiseera ky’okusiba PTFE ku 360-400°C n’okuwonya okusiiga ku 150-200°C,... olugoye lwa fiberglass luyita mu kugaziwa okw’ebbugumu era ekisinga obukulu, okukendeera okutakyuka okuva ku situleesi y’okuluka esigaddewo. Singa situleesi eno teggyibwawo nga tennasiigibwa, efuuka ekikyamu ekikwese – ekivaako olutambi okukendeera, okuzingulula, oba okukutuka ng’efumbiddwa.

Aokai PTFE ekozesa ebikozesebwa ebya fiberglass ebiteekeddwa mu bbugumu mu bujjuvu okumalawo ekizibu kino. Ekiwandiiko kino kinnyonnyola ekikolo ekivaako okukendeera kw’ebbugumu, ebikosa ku buli mutendera gw’okulongoosa, n’ekisengejjero ekikulu: olugoye oluteekeddwateekeddwa mu bbugumu nga terunnabaawo nga lukendedde <0.5% ku 400°C.

Ekikolo Ekivaako – Stress esigaddewo okuva mu kuluka

Okukendeera kw’ebbugumu mu musingi kusibuka ku situleesi ey’omunda esigaddewo ekuŋŋaanyiziddwa mu kiseera ky’okukuba ebifaananyi eby’obuwuzi bw’endabirwamu n’okuluka olugoye. Olugoye lwa fiberglass olutaliimu bbugumu mu bujjuvu lujja kuyita mu kukendeera okutakyuka oluvannyuma lw’okubuguma waggulu w’ekipimo kyalwo eky’okufulumya situleesi (okukendeera okw’ekitalo kutandika waggulu wa 300°C).

Stress yonna ey’okukendeera efulumiziddwa mu bujjuvu oba etaziyiziddwa efuuka ekizibu ekikulu ekikwekeddwa ekivaako ebipimo bya tape ebitali binywevu. Stress eno 'sibirwa' mu nsengekera y'olugoye mu kiseera ky'okuluka era efuluma nga efumbiddwa okutuuka ku bbugumu erimala.

Impact Mu kiseera kya PTFE Sintering – Omutendera Omukulu

PTFE sintering temperature etuuka ku 360-400°C, esukkulumye nnyo ku bbugumu eritandikirawo fiberglass thermal shrinkage, ekifuula omutendera guno ensonga esalawo ku dimensional performance.

1. Locked shrinkage stress ekola ebikyamu ebikusike mu bipimo

Singa ekolebwa wansi w’okusika omuguwa okutono, olugoye lwa fiberglass lukendeera mu ddembe era mu ngeri ey’amaanyi, ekivaamu ebipimo by’obuwanvu n’obugazi ebitali ku mutindo. Singa okusika okuyitiridde kussibwa okuziyiza okukendeera, ebiwuzi by’endabirwamu biwanvuwa n’amaanyi. Ku 380°C, PTFE esaanuuse eyingira n’ezinga ebiwuzi ebigoloddwa; oluvannyuma lw’okunyogoga n’okubumba, enkola y’okukendeera okukwekeddwa esibirwa enkalakkalira munda mu substrate nga massive residual tensile stress. Oluvannyuma lw’olutambi okuddamu okubuguma mu nkola ez’oluvannyuma, okunyigirizibwa kuno okusigaddewo kuleeta okukendeera kwa substrate era butereevu okwonoona obutebenkevu bw’ebipimo.

2. Obupapajjo bwa substrate obutali bwenkanya butyoboola obumu bw’okusiiga

Emiwendo gy’okukendeera kw’ebbugumu okutakwatagana mu bitundu by’olugoye eby’enjawulo (okugeza, edge vs. central area) mu kiseera ky’okusiba bivaako okukyukakyuka omuli empenda eziriko amayengo, ku mabbali g’ebikopo, n’okubumbulukuka kungulu . Obugulumivu bwa substrate obutali bwenkanya buleeta obuwanvu bw’okusiiga okwesiba obutali bwenkanya mu nkola eziddako, kyangu okuleeta ebiwujjo by’empewo oba okunywerera okubi mu kiseera ky’okusiba, era mu ngeri etali butereevu kwonoona obutebenkevu bw’ebipimo n’emirimu gy’obutambi obuwedde.

Okukosebwa Mu kiseera ky’okuwonya mu ngeri ey’okusiiga – Okukendeeza ku situleesi ey’okubiri

Enkola z’okusiiga (ebisiiga ebikwatagana ne puleesa ya silikoni, ebisiiga ebya acrylic, n’ebirala) biwona ku 150-200°C. Ebbugumu lino liri wansi okusinga sintering range naye nga limala okukola residual locked stress munda mu substrate, okuleeta ebivaamu ebibi ebingi.

1. Okukendeera okw’okubiri kuleeta obulema ku ngulu n’okukyama mu bipimo

Bw’oyingira mu oven y’okuwonya, okunyigirizibwa kw’okukendeera okusigadde munda mu substrate kufulumya era ne kuleeta okukendeera kwa tape okupima. Kino kivaako:

• Okukendeeza ku bugazi obuyitiridde

• Micro-cracks, orange peel texture, oba okulemererwa okukwatagana ku adhesive surface (nga okukendeera kubaawo omulundi gumu n’okuwona) .

• Enkyukakyuka mu buwanvu mu buwanvu bw’ekisiiga n’okunyiganyiga kwa layini ezifulumya (olw’obutakwatagana wakati w’embiro z’okukendeera kw’olugoye n’embiro za layini y’omuzingo gw’okusiiga)

2. Thermal curling emalawo processing precision

Layer ya substrate actively contracts under heated residual stress, ate fully cured adhesive layer erina omugerageranyo ogw’enjawulo ogw’okugaziwa kw’ebbugumu, ekivaamu obutakwatagana bwa stress obw’amaanyi wakati wa layers bbiri. Teepu ekulukuta amangu ddala nga esekuddwa okuva mu layini ezifulumya oba ng’efunye ebbugumu nga ekozesebwa – okulemererwa okugalamira nga fulaati n’okufiirwa okufugibwa kw’ebipimo n’okukola.

Okusumululwa kw’okunyigirizibwa okutambula obutasalako mu kiseera ky’okukozesa enkomerero – Obutabeera mu ntebenkevu obw’ekiseera ekiwanvu

Okunyigirizibwa kw’okukendeera okusigaddewo okutaggyibwawo mu bujjuvu mu kiseera ky’okuwonya okusiiga kusigala mu kusiiga ebintu ebiwedde. Mu mbeera z’okusiiga okw’ebbugumu eringi, okusiba ebbugumu, oba enzirukanya y’ebbugumu (okugeza, okusiiga pawuda mu 260°C), olutambi lukendeera mpolampola era obutasalako.

Ebiddirira:

• Ensalo z’okusiba ezikyusiddwa (layini z’okusiba zitambula) .

• Okusitula edge oba okulemererwa okunyweza

• Okufiirwa ddala okutebenkera kw’ebipimo

Eno y’ensonga lwaki obutambi obumu bulemererwa mu nnimiro ne bwe buba nga buyise mu kukeberebwa okusooka – situleesi enkweke efuluma mpola mu kiseera n’ebbugumu.

Core Solution – Ggyawo Okukendeera Nga Tonnaba Sintering

Okukola dimensionally stable PTFE adhesive tapes, okukaka okusika okugolola mu kiseera ky’okulongoosa tekisobola kugonjoola nsonga za kukendeera mu musingi. Okuggyawo ddala okukendeera kwa fiberglass kulina okutuukibwako ku nsibuko.

1. Enkola ya Aokai PTFE

1. Kozesa olugoye lwa fiberglass base oluteekeddwa mu bujjuvu mu bbugumu (nga terunnakendeezebwa) – omuwendo gw’okukendeera kw’ebbugumu gufugibwa nnyo wansi wa 0.5% wansi w’embeera y’okugezesa eya 400°C × eddakiika 10 (omutindo omukakali guliwo ku ddaala ery’omutindo).

2. Okwongerako enkola ey’ebbugumu eringi nga tonnaba kugikuba nga tonnaba kufukirira oba kusiiga PTFE – okusobozesa olugoye lwa fiberglass okumaliriza okukendeera okw’obwereere n’okufulumya mu bujjuvu situleesi yonna ey’omunda nga tonnayingira mu kitundu eky’okusiba.

2. Ekivaamu

Oluvannyuma lw’okukendeera kw’ebbugumu ly’olugoye lwa fiberglass, enkyukakyuka mu bipimo mu kiseera ky’okusiba n’okuwonya okw’okusiiga okuddirira zijja kuva ku kugaziwa n’okukonziba kw’ebbugumu kwokka okwa resin ne layers ezisiiga – nga zirina obunene obutono ennyo okusinga okukendeera okusigalira okuva ku situleesi. Kino mu musingi kikakasa nti:

• Okutebenkera mu bipimo (obuwanvu n’obugazi) .

• Obupapajjo ku ngulu

• Okugumira ebbugumu n’okwesigamizibwa okumala ebbanga eddene

Aokai PTFE elonda ebitundu bya fiberglass byokka ebiteekeddwa mu bbugumu mu bujjuvu nga biriko emiwendo gy’okukendeera egyawandiikibwa. Tusobola okuwa data y’okugezesa buli kasitoma byetaago.

Mu bufunze – Omusingi gw’okukendeera nga tegunnabaawo

Aokai PTFE ekuwa amagezi okukozesa fiberglass nga tennateekebwa mu bbugumu nga ekendedde <0.5% ku nkola zonna ezikulu mu bipimo. Ku bakasitoma abeetaaga ebipimo ebinywevu ennyo, tuwaayo ebika eby’omutindo ogwa waggulu nga bikendedde <0.3% ku 400°C.
