Vuyelo bya Mpimo wa ku Hisisa eka Lapi ra PTFE ra Mahiselo ya le Henhla

Jiangsu Aokai New Materials, muendli wa xihlovo wa lapi ra mahiselo yale henhla ya PTFE, u ta ku hlamusela leswaku eka endlelo ro sintering ro humelerisa lapi ra mahiselo yale henhla ya PTFE hiku chekisa lapi ra fibre ya nghilazi hi PTFE emulsion, mpimo wo hisa i parameter ya nkoka leyi lawulaka khwalithi ya xitirhisiwa lexi hetiweke. Kungava hiku hatlisa swinene kumbe hiku nonoka swinene ku hisa swita kavanyeta ntshikelelo na mass transfer balance hinkarhi wa ku endliwa ka lapi ra PTFE ra mahiselo yale henhla.

I. Makhombo ya ku Hisisa hi ku Nonoka Ku tlula mpimo eka Lapi ra PTFE ra Mahiselo ya le Henhla

·  Blistering : Loko ku hisa ku nonoka ngopfu hi nkarhi wa vuhumelerisi bya lapi ra mahiselo yale henhla ya PTFE hiku chekisa lapi ra glass fibre hi PTFE emulsion, swilo swa organic swofana na surfactants na stabilizers eka emulsion swita hundza eka pyrolysis yo leha, leswi humesaka nhlayo leyikulu ya gasi. Hi nkarhi walowo, PTFE yi tsindziyela ka ha ri na nkarhi, yi pfalela tichannel ta gasi eka lapi ra fibre ya nghilazi, yi khoma swiphemuphemu swa ntshikelelo wa le henhla endzeni ka xifunengeto naswona yi endla leswaku ku va na swirhumbana swa le henhla eka lapi ra PTFE ra mahiselo yale henhla leri hetiweke.

·  Kuhunguteka ka Ku Namarhela : Ku hisa hiku nonoka swiyisa eka ku endliwa ka brittle diffusion layer yo tiya swinene eka interface exikarhi ka PTFE na glass fibre cloth, leswi nyanyisaka ku nga fambelani ka thermal expansion naswona xisweswo swihunguta ku namarhela exikarhi ka coating na substrate hi nkarhi wa vuhumelerisi bya PTFE high-temperature cloth.

II. Makhombo ya Ku Hisisa Hi Ku Hatlisa Ku tlula mpimo eka Lapi ra PTFE ra Mahiselo ya le Henhla

·  Ku pandzeka : Ku hisa hiku hatlisa swinene swi humesa ntshikelelo lowukulu wa mahiselo hinkarhi wa vuhumelerisi bya lapi ra mahiselo yale henhla ya PTFE hiku chekisa lapi ra fibre ya nghilazi hi PTFE emulsion. Hikwalaho ka ku hambana lokukulu eka thermal expansion coefficients exikarhi ka PTFE na glass fibre cloth, ku hisa hiku hatlisa swiendla leswaku vuandlalo bya coating byi sinter hiku hatlisa loko endzeni ka yona yi tsandzeka ku olovisa hi nkarhi, leswi endlaka leswaku kuva na micro-cracks kumbe hambi kuri through-cracks, leswi onhaka swinene vutshembeki bya xivumbeko xa PTFE high-temperature cloth.

·  Blistering and Poor Adhesion : Ehansi ka ku hisa hi xihatla, ntshikelelo wa vapor lowu endliwaka hiku bola ka xihatla ka swilo swa organic awu koti ku baleka hiku tirhisa coating surface leyi pfaleriweke, leswi endlaka ti dense bubbles. Hi nkarhi lowu fanaka, emulsion ya PTFE yi tsandzeka ku tsakamisa hi ku helela lapi ra fibre ya nghilazi, leswi vangaka swihoxo swa interface bonding naswona swi hunguta swinene ku namarhela ka lapi ra PTFE ra mahiselo yale henhla.

Ku papalata swihoxo leswinga laha henhla xikan’we naku humelerisa lapi ra xiyimo xale henhla ra PTFE ra mahiselo yale henhla, Aokai yi lawula swinene mpimo wa ku hisa eka vuhumelerisi bya xiviri hiku amukela ku hisa ka magoza  (xikombiso, mahiselo ya kamara → 120°C eka ku susiwa ka binder → sintering hiku hatlisa ehenhla ka 300°C), ku ringanisela ku humesiwa ka gasi xikan’we naku ntshunxeka ka ntshikelelo.

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

Loko u lava ku dyondza swo tala hi tipharamitha leti nga na vuxokoxoko, swiyimo swa xikombelo na swintshuxo leswi endleriweke nxaxamelo wa hina hinkwawo wa swikumiwa, ku katsa na lapi ra mahiselo ya le henhla ya PTFE, thepi ya mahiselo ya le henhla ya PTFE, bandi ra mesh ra mahiselo ya le henhla ya PTFE, mabandhi lama nga na swirhabyani ya michini yo boha, lapi ra PTFE ra tlhelo rin’we, mabandhi ya conveyor lama lwisanaka na mahiselo ya le henhla na ku lwisana na mahiselo ya le henhla lapi ra fibre ya nghilazi, hi kombela u hi tihlanganisa hi tindlela leti landzelaka:

·  Nomboro ya Vukorhokeri: Tatana Guo 18944819998

·  Nkulukumba Liu 13705266308

Minkarhi hinkwayo hi seketela filosofi ya vukorhokeri ya vutshila na vutshembeki, naswona hi tinyiketerile ku ku nyika swintshuxo swa xiyimo xin’we na vukorhokeri lebyi nga na vukheta!
