Lwaki olugoye lwa Glass Fiber lulina Dewaxing nga terunnafukibwako PTFE Emulsion? Omusingi gwe guliwa?

Ng’omukugu mu kukola emifaliso egy’ebbugumu eringi erya PTFE, Aokai New Materials ekola obujjanjabi obw’ebbugumu eringi ku lugoye olwa fiber y’endabirwamu. Nga tetunnafukibwa na PTFE (Polytetrafluoroethylene) emulsion, olugoye lw’obuwuzi bw’endabirwamu luyita mu kuggyibwako omubisi n’okuggyamu ebiwuziwuzi okuggyawo ebirungo ebipima obunene (ebiyamba ku lugoye) ku ngulu w’obuwuzi. Ebiyambi bino bikola mu kusiba, okusiiga n’okukuuma mu kiseera ky’okukuba ebiwuzi n’okuluka. Wabula singa teziggyibwawo, zijja kukosa nnyo omutindo gw’ebintu ebikoleddwa mu PTFE ne glass fiber. Emisingi okusinga giri bwe giti:

1. Ggyawo Ebintu Ebirimu Amaanyi Amatono ku Ngulu n’Okulongoosa Obunnyogovu

Paraffin, amafuta agasiiga n’ebitundu ebirala mu bikozesebwa ebipima obunene (sizing agents) bintu bya maanyi matono ku ngulu. Singa ekuumibwa, emulsion ya PTFE (erimu okusika omuguwa okutono ku ngulu naye nga kwetaagisa nnyo) tesobola kusaasaana kyenkanyi ku ngulu w’obuwuzi bw’endabirwamu, ekivaamu obulema nga ebinnya n’amaaso g’ebyennyanja. Okuyita mu kwoza okw’ebbugumu eringi oba okuyonja mu ngeri ey’ekizimbulukusa, obucaafu buggyibwawo era amaanyi ag’okungulu ag’obuwuzi bw’endabirwamu ne geeyongera, ekisobozesa okufukirira mu bujjuvu nga PTFE.

2. Okuziyiza Carbonization ne Delamination mu kiseera ky’okusiba mu bbugumu erya waggulu

Ebbugumu ly’okusiba (sintering temperature) lya PTFE liri waggulu nga 360–380°C. Ebisigalira bya paraffin oba epoxy ku ngulu w’obuwuzi bw’endabirwamu bijja kukola kaboni ku bbugumu erya waggulu bwe lityo, ne bivaamu obutundutundu obuddugavu oba ggaasi. Kino tekikoma ku kwonoona kitundu (ekikosa eby’obugagga bya dielectric mu laminates ezibikkiddwa ekikomo eza frequency enkulu) naye, ekisinga obukulu, oluwuzi olufuuse kaboni lukola ensengekera enafu, okukendeeza ennyo ku maanyi g’okukwatagana wakati wa PTFE ne fiber y’endabirwamu era ne kireeta okusasika kw’ekintu ekigatta.

3. Teekawo 'Mechanical Anchoring' Effect ey'amaanyi

Okuggyamu omubisi n'okuggyamu ebikuta eby'omutindo ogwa waggulu (naddala okulongoosa mu bbugumu erya waggulu) kisingako ku 'okuyonja' kwokka. Nga ebirungo ebiramu biggyibwawo, kungulu kw’obuwuzi bw’endabirwamu buwandiikibwako katono okukola micropores oba okulaga ebibinja bya silanol ebisingawo (-OH). Kino kireeta embeera z'okusiiga ekirungo ekigatta ekiddako (okugeza, phenyl silane), okusobozesa PTFE okukola ebiyungo by'eddagala oba ebifo eby'okusiba eby'omubiri n'obuwuzi bw'endabirwamu okuyita mu bikozesebwa ebiyunga — okukyusa 'okusiiga' okwangu mu 'okusiba' okunywevu.

4. Weewale Okwonooneka kw’Eby’obusannyalazo (Interfacial Dielectric Properties).

Mu nkola ez’omulembe nga laminates ezibikkiddwa ekikomo eza frequency enkulu n’ez’amaanyi, ebintu ebisigadde eby’obutonde (wax, gum) byongera nnyo okufiirwa kwa dielectric wansi w’ebbugumu erya waggulu ne frequency eya waggulu. Dewaxing ne degumming kikakasa nti glass fiber-PTFE composite ekuuma dielectric constant entono ennyo n’okufiirwa dielectric.

Mu bufunze, ekigendererwa ekikulu eky’obujjanjabi buno kwe kumalawo layini z’ensengekera enafu n’okukakasa nti PTFE, ekintu eky’amaanyi amatono ku ngulu, kituuka ku kufukirira okutuukiridde n’okukwatagana okw’amaanyi amangi ku fiber y’endabirwamu ennyonjo, ey’amaanyi amangi ku ngulu.

Amawulire ago waggulu gaweereddwa kkampuni ya Jiangsu Aokai New Materials Technology Co., Ltd.
