Ha Yini Lapi Ra Glass Fibre Ri Endliwa Hi Dewaxing Loko Ri Nga Si Cheriwa Hi PTFE Emulsion? Xana Nsinya wa Nawu i yini?

Tanihi muendli wa xiphurofexinali wa malapi ya mahiselo yale henhla ya PTFE, Aokai New Materials yi endla vutshunguri bya mahiselo yale henhla eka lapi ra fibre ya nghilazi. Loko kungase cheriwa hi PTFE (Polytetrafluoroethylene) emulsion, lapi ra glass fibre ri endliwa dewaxing na degumming kuva ku susiwa ti sizing agents (textile auxiliaries) eka vuandlalo bya fibre. Swipfuneti leswi switirha eka ku hlanganisiwa, ku cheriwa mafurha xikan’we naku sirhelela hinkarhi wa ku dirowa ka fibre naku luka. Hambiswiritano, loko tinga susiwi, tita onha swinene khwalithi ya composite ya PTFE na glass fibre. Misinya ya milawu ngopfu-ngopfu hi leyi landzelaka:

1. Susa Swilo swa Eneji ya le Hansi ya le Henhla na ku Antswisa ku tsakama

Paraffin, mafurha yo tola na swiphemu swin’wana eka switirhisiwa swo pima i swilo swa eneji yale hansi yale henhla. Loko yi hlayisiwile, PTFE emulsion (leyi nga na tension yale hansi yale henhla kambe swilaveko swo tika) ayi koti ku hangalaka hiku ringana eka vuandlalo bya fibre ya nghilazi, leswi endlaka leswaku kuva na swihoxo swofana na ti craters na mahlo ya tihlampfi. Hiku tirhisa ku basisiwa ka mahiselo yale henhla kumbe ku basisiwa ka solvent, swilo leswi thyakeke swa susiwa naswona matimba yale henhla ya fibre ya nghilazi ya engeteriwa, leswi endlaka leswaku kuva na ku tsakama hiku hetiseka hi PTFE.

2. Sivela Carbonization na Delamination Hi nkarhi wa High-Temperature Sintering

Mahiselo ya sintering ya PTFE yale henhla kuya fika eka 360–380°C. Swinamarheti leswi saleke swa paraffin kumbe epoxy eka vuandlalo bya fibre ya nghilazi swi ta va na khaboni eka mahiselo ya le henhla swonghasi, swi humesa swiphemuphemu swa ntima kumbe gasi. Leswi aswi thyakisi ntsena medium (leswi khumbaka swivumbeko swa dielectric eka high-frequency copper-clad laminates) kambe, xa nkoka swinene, carbonized layer yi endla interface yoka yinga tsana, leswi hungutaka swinene matimba ya bonding exikarhi ka PTFE na glass fibre naswona swivanga delamination ya composite material.

3. Simeka Vuyelo bya 'Mechanical Anchoring' lebyi Tiyeke

Dewaxing ya xiyimo xale henhla na degumming (ngopfu ngopfu vutshunguri bya mahiselo yale henhla) swi tlula 'ku basisa' ntsena. Loko organic matter yi susiwa, vuandlalo bya fibre ya nghilazi byi etched nyana kuva byi endla ti micropores kutani byi paluxa mintlawa yotala ya silanol (-OH). Leswi swi tumbuluxa swiyimo swa ku peta swiaki swa xihlanganisi leswi landzelaka (xikombiso, phenyl silane), leswi pfumelelaka PTFE ku vumba swihlanganisi swa tikhemikhali kumbe tindhawu ta physical anchoring na fibre ya nghilazi hi ku tirhisa switirhisiwa swo hlanganisa — ku hundzula 'coating' yo olova ku va 'bonding' yo tiya.

4. Papalata Ku Onhaka ka Swihlawulekisi swa Dielectric swa Interfacial

Eka switirhisiwa swale henhla swofana na high-frequency na high-speed copper-clad laminates, residual polar organic substances (wax, gum) yi engetela swinene ku lahlekeriwa hi dielectric ehansi ka mahiselo yale henhla xikan’we na frequency yale henhla. Dewaxing na degumming switiyisisa leswaku glass fiber-PTFE composite yi hlayisa dielectric constant yale hansi swinene xikan’we na ku lahlekeriwa hi dielectric.

Hiku komisa, xikongomelonkulu xa vutshunguri lebyi i ku herisa ti interface layers letinga tsana naku tiyisisa leswaku PTFE, xitirhisiwa xa eneji yale hansi yale henhla, xi fikelela ku tsakama loku hetisekeke xikan’we naku hlanganisiwa ka matimba yale henhla eka fibre ya nghilazi leyi tengeke, ya eneji yale henhla yale henhla.

Rungula leri nga laha henhla ri nyikiwile hi Jiangsu Aokai New Materials Technology Co., Ltd.

Ku kuma tipharamitha ta vuxokoxoko, swiyimo swa xikombelo na swintshuxo leswi endleriweke ku tirhisiwa ka nxaxamelo wa hina hinkwawo wa swikumiwa — ku katsa na malapi ya mahiselo ya le henhla ya PTFE, tithepi ta mahiselo ya le henhla ya PTFE, mabandhi ya mesh ya mahiselo ya le henhla ya PTFE, mabandhi lama nga riki na swirhabyani ya michini yo boha, lapi ra PTFE ra tlhelo rin’we, mabandhi ya conveyor lama lwisanaka na mahiselo ya le henhla, lapi ra fibre ra nghilazi leri tiyiselaka ku hisa na swin’wana — hi kombela u ntshunxeka ku hi tihlanganisa:

Hi seketela filosofi ya vutirheli bya xiphurofexinali na byo tshembeka, naswona hi tinyiketerile ku ku nyika swintshuxo swa xiyimo xin’we na vukorhokeri byo nyikela nyingiso!
