Basic Process Flow for Okufukirira Olugoye lwa Fiberglass ne PTFE Emulsion

Jiangsu Aokai New Materials, omukugu mu kukola olugoye olwa PTFE olw’ebbugumu eringi, etuwa ennyanjula enzijuvu. Enkola y’okufukirira olugoye lwa fiberglass n’okusaasaana kwa PTFE ye tekinologiya omukulu okusiiga n’okusiba polytetrafluoroethylene kyenkanyi ku fiberglass substrate, okukola ebintu ebigatta ebirimu okugumira ebbugumu eringi, okuziyiza amasannyalaze n’okukola obutakwata. Ebintu nga bino bikozesebwa nnyo mu laminates ezibikkiddwa ekikomo eza frequency enkulu, conveyor belts ezitali za bbugumu erya waggulu, ebikozesebwa mu membrane y’okuzimba n’emirimu emirala.

Enkola enkulu enzijuvu erimu emitendera musanvu emikulu nga gino wammanga:

1. Okusooka okulongoosa olugoye lwa fiberglass (Okuggyamu omubisi / Okuggya obunene) .

Guno gwe mutendera ogusinga obukulu nga tonnaba kujjanjaba. Ekirungo ekigerageranya obunene bw’engoye (okusinga paraffin wax, ebiva mu sitaaki) kisiigibwa ku fiberglass filaments nga baluka; okuggyawo okutali kujjuvu kijja kwonoona nnyo enkolagana wakati wa PTFE n’ebiwuzi by’endabirwamu.

· Enkola enkulu ey’okulongoosa: Olugoye luyita mu kyokero eky’ebbugumu eringi okusobola okuggyamu amazzi mu bbugumu ku 350 ~ 400°C, ne lufuuka oxidizing mu bujjuvu n’okuvunda ebirungo byonna ebikola obunene bw’ebiramu.

· Enkwata y’okugoberera: Olugoye olutaliimu ‘wax’ lunyogozebwa, oluusi ne lunaazibwa n’amazzi amayonjo oba n’ebizigo by’eddagala okumalawo evvu erisigaddewo, oluvannyuma ne lukalibwa okufuna olugoye oluyonjo olweru olutaliiko kintu kyonna nga lwetegefu okufukibwa.

2. Enkola ya PTFE Emulsion

· Ebintu ebisookerwako: Okusaasaana kwa PTFE okusengekeddwa nga kulina ebikalu ebituufu nga 60%.

· Enkola y’okutabula: Fuula okusaasaana kwa sitokisi n’amazzi agataliimu ayoni okutuuka ku kigero ekigendererwa (40%–55%) okusinziira ku kutikka resin okwetaagisa n’obuzito bw’okufukirira. Ekirungo ekituufu ekikola ku ttaka (surfactant) kyongerwako okutumbula omulimu gw’okufukirira ku fiberglass; ekizitowa kiyinza okuteekebwamu okutereeza obuzito bwe kiba kyetaagisa.

3. Okufunyisa embuto

Ekigendererwa ekikulu kwe kuyingira mu bujjuvu kwa PTFE emulsion mu fiber bundles ne interstices z’olugoye olulukibwa.

1. Enkola ya Dip-Squeeze (Esinga okukozesebwa): Olugoye lulung’amibwa okuyita mu biwujjo ebinnyika okusobola okunnyika mu bujjuvu mu ttanka ya emulsion, olwo ne luyita mu bipimo bibiri ebisika. Obuzito bw’okusiiga bufugibwa nga tutereeza puleesa ya roller nip okufulumya emulsion eyitiridde n’okusaasaanya resin mu ngeri y’emu.

2. Doctor Blade Coating: Emulsion esaasaanyizibwa ku ngulu w’olugoye ng’eyita mu blades z’ebyuma, ezisaanira okusaasaana okw’obuzito obw’amaanyi.

4. Okukala

Olugoye olufukiddwamu luyingira mu oven ekaza ey’ebbugumu eri wansi ekola ku 100~150°C.

· Ekigendererwa: Fuumuula mpola amazzi n’ebitundu ebikola ku ttaka, okole firimu enkalu wadde etali ya kunywera ey’obutundutundu bwa PTFE ku ngulu w’obuwuzi.

· Okufuga ebbugumu note: Ebbugumu erisukkiridde lijja kukola mangu firimu enzito ey’okungulu, okutega obunnyogovu obw’omunda obufuumuuka okukola ebituli bya ppini n’ebizimba.

5. Okusiba (Okuwonya mu bbugumu) .

Olugoye olukalu luyingizibwa mangu mu kyokero eky’ebbugumu eringi okusobola okulongoosebwa mu bbugumu ku 360~390°C (okutuuka ku 400°C ku ddaala erimu).

· Enkola: PTFE ye polimeeri ekola obuveera obw’ebbugumu. Ku bbugumu erisukkulumye nnyo ku kifo kyayo eky’okusaanuuka (327°C), obutundutundu bwa PTFE busaanuuka, bukulukuta ne butereera okukola firimu egenda mu maaso, ne butuuka ku kukwatagana okw’ebyuma n’okunywerera ku ngulu za fiberglass.

· Okugabanya emitendera: Ekitundu ky’okusiba (sintering zone) kyawulwamu ebitundu by’okufumbisa (heating ramp, constant-temperature sintering and cooling segments) okukakasa okuyungibwa kw’obutundutundu obujjuvu awatali kuvunda kwa bbugumu.

6. Okufukirira & Sintering mu mitendera mingi

Enzirukanya emu ey’okufukirira-okusiba (impregnation-sintering cycle) yokka ekola ekizigo ekigonvu ennyo ekitera okubeera n’obulema mu kinnya kya ppini. Okutuuka ku buwanvu bw’okusiiga ekigendererwa n’ebirimu resin (okugeza, 45%–65% resin loading for high-frequency copper-clad laminate substrates), omutendera omujjuvu ogw’okufukirira → okukala → okusiba  guddibwamu emirundi 2 ku 4 oba okusingawo. Buli nsengekera eyongera okujjuza ebituli by’obuwuzi era n’eyongera ku buwanvu bw’okusiiga, okukkakkana ng’ekola ekipande ekinene ekitaliimu ppini.

7. Oluvannyuma lw’okujjanjaba & Okuzingulula

1. Okukyusa kungulu: Oluvannyuma lw’okuyita mu sintering okusembayo, okulongoosa corona oba chemical sodium-naphthalene etching kuyinza okukozesebwa okulongoosa okunyweza kungulu awatali kwonoona substrate, okwanguyiza okuddirira copper cladding oba secondary coating.

2. Edge trimming & winding: Empenda z’olugoye zisalibwa butereevu, olwo olugoye oluwedde ne luzingibwa bulungi n’ekyuma ekitwala.

3. Okukebera omutindo: Okugezesa okujjuvu kw’ebintu ebiwedde omuli obuzito obusookerwako, obuwanvu, amaanyi g’okusika, amaanyi g’okusekula, obutakyukakyuka bwa dielectric n’obulema obulabika ku ngulu.

Ebifo Ebikulu Ebifuga Enkola

Ebipimo ebikulu ebifuga omutindo gw’ebintu ebiwedde bye bino: okuggya obunene/okuggyamu amazzi mu mubiri mu bujjuvu, okufukirira mu bujjuvu mu emulsion, okukala mpolampola mu bbugumu eri wansi, okuteekawo ebbugumu ly’okusiba mu ngeri entuufu, n’obungi bw’okusiiga obutakyukakyuka oluvannyuma lw’enzirukanya z’okufukirira eziwera.
