Phallo ea Ts'ebetso ea Motheo bakeng sa ho Impa Lesela la Fiberglass le PTFE Emulsion

Jiangsu Aokai New Materials, moetsi ea hloahloa oa lesela la mocheso o phahameng oa PTFE, o fana ka kenyelletso e felletseng. Mokhoa oa ho kenya lesela la fiberglass ka PTFE dispersion ke thekenoloji ea mantlha ea ho roala le ho sinter polytetrafluoroethylene holim'a fiberglass substrate, ho etsa lisebelisoa tse nang le likarolo tse nang le mocheso o phahameng oa mocheso, motlakase oa motlakase le ts'ebetso e sa tsitsang. Lihlahisoa tse joalo li sebelisoa ka ho pharaletseng ka li-laminates tsa koporo tse nang le maqhubu a phahameng a mangata, mabanta a conveyor a nang le mocheso o phahameng a se nang lithupa, lisebelisoa tsa membrane ea meralo le masimo a mang.

Ts'ebetso ea mantlha e felletseng e na le mehato e supileng ea bohlokoa ka tsela e latelang:

1. Fiberglass Fabric Pretreatment (Dewaxing / Desizing)

Ena ke mohato oa bohlokoa ka ho fetisisa pele ho phekolo. Moemeli oa boholo ba masela (haholo-holo boka ba parafine, lintho tse tsoang ho starch) o apesitsoe ka likhoele tsa fiberglass nakong ea ho loha; ho tlosoa ho sa phetheheng ho tla senya haholo maqhama a sefahleho pakeng tsa PTFE le likhoele tsa khalase.

· Mokhoa o ka sehloohong oa phekolo: Lesela le tsoela pele ho feta ka har'a sebōpi sa mocheso o phahameng oa mocheso bakeng sa dewaxing ea mocheso ho 350 ~ 400 ° C, ho hlahisa oxidizing ka ho feletseng le ho senya lisebelisoa tsohle tsa manyolo.

• Ts'ebetso ea morao-rao: Lesela le entsoeng ka boka le theoleloa fatše, ka linako tse ling le hlatsuoa ka metsi a hloekileng kapa ka metsoako ea lik'hemik'hale ho felisa molora o setseng, ebe le omisoa ho fumana lesela le hloekileng le lesoeu le se nang letho le loketseng ho kenngoa.

2. Tlhahiso ea Emulsion ea PTFE

· Lintho tse tala: Phatlalatso e matla ea PTFE e nang le litaba tse tiileng tse ka bang 60%.

Ts'ebetso ea ho kopanya: Fokotsa phallo ea setoko ka metsi a hloekisitsoeng ho ea sebakeng se lebeletsoeng (40% -55%) ho ipapisitse le ho kenya resin le viscosity e hlokahalang. surfactant e loketseng e eketsoa ho boost wetting performance on fiberglass; thickener e ka kenyelletsoa ho fetola viscosity ha ho hlokahala.

3. Ho ima

Sepheo sa mantlha ke ho kenella ka botlalo ha PTFE emulsion ka har'a dingata tsa fiber le li-interstices tsa lesela le lohiloeng.

1. Dip-Squeeze Method (Ka ho fetisisa e amohetsweng ka ho fetisisa): Lesela le tataisoa ka ho qoelisoa ka ho qoelisoa ho kena ka ho feletseng ka tanka ea emulsion, ebe le feta har'a li-roller tsa ho penya. Boima ba ho roala bo laoloa ka ho fetola khatello ea roller nip ho extrude emulsion e feteletseng le ho aba resin ka mokhoa o ts'oanang.

2. Ngaka Blade Coating: Emulsion e hasana holim'a lesela ka mahare a tšepe, a loketseng li-dispersions tse phahameng tsa viscosity.

4. Ho omisa

Lesela le kentsoeng le kenngoa ka ontong e omisang mocheso o tlase e sebetsang ho 100 ~ 150 ° C.

• Morero: Moafatsa metsi le li-surfactants tse sa fellang, 'me u thehe filimi e ommeng e sa tsitsang ea likaroloana tsa PTFE holim'a fiber.

• Tlhokomeliso ea taolo ea mocheso: Mocheso o phahameng ka ho fetesisa o tla etsa filimi e teteaneng ka potlako, e koale mongobo o ka hare o fetohang mouoane ho etsa masoba le machache.

5. Sintering (Thermal Curing)

Lesela le omisitsoeng le kenngoa hang-hang ka sebōping sa mocheso o phahameng oa mocheso bakeng sa phekolo ea mocheso ho 360 ~ 390 ° C (ho fihlela ho 400 ° C bakeng sa limaraka tse ling).

· Mechanism: PTFE ke polymer ea thermoplastic. Lithempereichara tse ka holimo ho ntlha ea ho qhibiliha ha eona (327 ° C), likaroloana tsa PTFE lia qhibiliha, li phalla 'me li lekanngoa ho etsa filimi e tsoelang pele, ho finyella ho kenngoa ha mechine le ho khomarela ka holim'a fiberglass.

· Karohano ea sethala: Sebaka sa sintering se arotsoe ka tsela ea ho futhumatsa mocheso, mocheso o sa khaotseng oa sintering le likarolo tse pholileng ho netefatsa motsoako o felletseng oa likaroloana ntle le ho senyeha ha mocheso.

6. Multi-Cycle Impregnation & Sintering

Potoloho e le 'ngoe ea ho inregnation-sintering e hlahisa feela lesela le tšesaane haholo le nang le mathata a masoba. Ho finyella sepheo sa ho roala botenya le li-resin content (mohlala, 45% -65% resin loading for high-frequency copper-clad laminate substrates), tatellano e feletseng ea impregnation → ho omisa → sintering  e phetoa ka makhetlo a 2 ho isa ho a 4 kapa ho feta. Potoloho e 'ngoe le e 'ngoe e tsoela pele ho tlatsa likheo tsa fiber le ho eketsa botenya ba ho roala, e qetellang e etsa letlapa le teteaneng le se nang likoti.

7. Ka mor'a Kalafo & Winding

1. Phetoho ea holim'a metsi: Ka mor'a hore ho be le sintering ea ho qetela, phekolo ea corona kapa k'hemik'hale ea sodium-naphthalene etching e ka sebelisoa ho ntlafatsa ho khomarela holim'a metsi ntle le ho senya substrate, ho thusa ho koahela koporo kapa ho roala ha bobeli.

2. Ho faola le ho phunya: Methapo ea masela e khaotsoe ka ho otloloha, ebe lesela le phethiloeng le lematsoa ka makhethe ke mochini o nkang.

3. Tlhahlobo ea boleng: Teko e felletseng ea lihlahisoa tse felileng ho kenyelletsa boima ba 'mele, botenya, matla a tsitsitseng, matla a peel, bofokoli ba dielectric le bofokoli ba pono.

Lintlha tsa Taolo ea Ts'ebetso ea Core

Mekhahlelo ea bohlokoa e laolang boleng ba sehlahisoa se felileng ke: ho tsitsa ka botlalo / dewaxing, ho kolobisa ka botlalo emulsion, ho omisa butle-butle ka mocheso o tlase, boemo bo nepahetseng ba mocheso oa sintering, le letsoalo le sa fetoheng la ho roala ka mor'a linako tse ngata tsa ho kenella.

Lintlha tse ka holimo tsa tekheniki li fanoa ke Jiangsu Aokai New Materials Technology Co., Ltd.

Haeba u batla ho fumana lintlha tse qaqileng, maemo a kopo le litharollo tse ikhethileng bakeng sa potefolio ea lihlahisoa tsa rona tse feletseng, ho kenyelletsa lesela la PTFE le mocheso o phahameng oa mocheso, tepi e khomarelang ea PTFE, lebanta la mocheso o phahameng oa mocheso oa PTFE, lebanta le se nang mocheso, lesela le le leng la PTFE, lesela le le leng le le leng la PTFE, lesela le le leng le le leng la PTFE, lesela le le leng le le leng la PTFE, lesela le nang le mocheso o phahameng ka tlas'a mocheso le conveyor conveyor ka kopo ikopanye le rona:
