Vulawuri lebyi kongomeke bya PTFE Coating Thickness eka Vuhumelerisi bya Malapi

Tanihi muendli wa xihlovo xa xiphurofexinali wa lapi ra mahiselo ya le henhla ya PTFE, . Jiangsu Aokai New Materials yi ku nyika nhlamuselo leyi nga ni vuxokoxoko. Eka endlelo ro chela malapi ya fibre ya nghilazi (kumbe ti fibre felts/textiles leti fanaka) hi PTFE emulsion, nsinya wa vulawuri bya vukulu wufana na ndlela ya ntolovelo ya dip-coating. Xiphiqo lexikulu xi le ka xivumbeko xa porous na lexi nga ringaniki xa ti fibre substrates. Hikokwalaho, xisekelo xa vulawuri bya vukulu iku ringanisela vuswikoti bya micro liquid absorption na ti macroscopic process parameters hi vukheta byale henhla.

1. Emulsion Formula: Yi kumisisa ku enta ka base ya leyara yin’wana na yin’wana yo peta

Solid content na viscosity : Amukela low solid content dispersion (xikombiso 45%) kuva yi endla coating yo olova hi pass xikan’we naku hunguta khombo ra drying cracking. Emulsion viscosity i xilotlelo xaku lulamisa fluidity xikan’we na nhlayo ya coating pickup.

2. Endlelo ro Chela: Ku ringanisela ka michini loku cinca-cincaka

Rivilo ro tlakusa / Ku tsindziyela : Rivilo ri endla xiboho xa ku enta ka filimi yo tsakama leyi vumbiwaka hi ku ringanisela ka matimba ya nkoka-misava na matimba ya viscous. Rivilo rale henhla ri rhwala emulsion yotala naswona ri endla filimi yo tiya yo tsakama.

Nkarhi wa impregnation xikan’we na fibre pretreatment : Tiyisisa ku tsakama hiku hetiseka xikan’we naku nghena ka ti fibre. Loko kungase cheriwa, ti burrs na thyaka eka vuandlalo bya fibre swifanele ku basisiwa kahle kuva switiyisisa ku peta loku fanaka xikan’we na matimba ya kahle swinene yo boha.

Multi-pass coating na post-treatment : Fikelela ku enta loku kongomisiweke hiku hlengeletiwa hakatsongotsongo. Leri i maqhinga ya nkoka yo fikelela vukulu lebyi lavekaka, hi ntolovelo ku landzela xirhendzevutani xa multiple impregnation — drying — sintering . Ku enta loku ringanyetiweke ka single-pass coating ku lawuriwa endzeni ka 0.01mm ~ 0.08mm.

·  Ku omisiwa : 100~150°C ku susa ndzhongho hiku hetiseka.

·  Ku baka : 280~290°C ku herisa swiaki swa le henhla. Ku omisiwa lokunga ringaniki naku baka swita endla leswaku kuva na ku pandzeka, ti bubbles kumbe ti pinholes eka coating.

·  Ku sintering : 360 ~ 390°C, ku khoma kuringana 30 ~ 90 wa tisekoni. Sintering yina nkoka swinene eka ku vumbiwa ka coating. Mahiselo yale hansi swinene ya endla leswaku kuva na ku hlangana lokunga kahle exikarhi ka coating na fibre; mahiselo yale henhla swinene yanga vanga ku bola ka resin.

3. Swilo swa Ntivo-mbango: Swilo leswi kucetelaka leswi nga lavekiki

Kutsakama : Kutsakama ka ndzhawu kufanele ku lawuriwa swinene eka 40%–60% RH . Kutsakama ka le hansi swinene swita endla leswaku kuva na nhlonge yale henhla xikan’we naku nghena loku ringaneleke endzeni; kutsakama lokukulu swinene kunga endla leswaku kuva na sagging, pinholes xikan’we naku hunguta ku namarhela.

Ku basa ka workshop : Lawula swinene ku basa ka workshop ku sivela swiphemuphemu leswi nga emoyeni ku wela eka thangi ro chela kumbe ku namarhela eka filimi leyi tsakamaka leyi nga omisiwangiki, leswi nga ta vanga swihoxo swa le henhla.

4. Swiringanyeto leswi Tirhaka & Vulawuri bya Khwalithi ya Closed-Loop

Nkongomiso wa vuhumelerisi : Switsundzuxiwa ku amukela maqhinga ya low concentration + multiple impregnation passes  kuva ku lawula kahle total coating thickness hiku lulamisa minkarhi ya impregnation. Hi nkarhi walowo, standardize maendlelo ya pre-treatment na post-treatment, lawa yanga masungulo ya coating ya xiyimo xale henhla.

Ku lulamisa swiphiqo : Loko ku pandzeka ka coating ku humelela endzhaku ka sintering, languta loko single-pass coating yi tsindziyerile ngopfu kumbe rivilo ro oma ri hatlisa ngopfu; loko ku namarhela ka coating kunga enelangi, kambela ku basa ka vuandlalo bya fibre xikan’we na mahiselo ya sintering xikan’we na nkarhi wo khoma.

Sisiteme ya khwalithi leyi pfalekeke : Simeka loji ya vuhumelerisi leyi heleleke:  Vulawuri bya parameter ya phurosese → Ku vekiwa tihlo ka nkarhi wa xiviri eka inthanete → Nxopaxopo wa tinhlayo ta swikumiwa leswi hetiweke → Mbuyelo wa ku antswisiwa ka phurosese .
PTFE impregnation i endlelo ro rharhangana ra physicochemical leri nga na ku hlanganisiwa ka swilo swo tala leswi cinca-cincaka. Ku lulama ka vukulu lebyi tiyeke swinga fikeleriwa ntsena hiku aka sisiteme ya vulawuri leyi ringaniseriweke leyi funengetaka fomula ya emulsion, ti parameters ta maendlelo na swiyimo swa mbango, xikan’we na tindlela to kambela leti fambelanaka.

Rungula leri nga laha henhla ri nyikiwile hi Jiangsu Aokai Switirhisiwa Leswintshwa Thekinoloji Co., Ltd.

Loko u lava vuxokoxoko lebyi dzikeke eka tipharamitha ta xithekiniki, swiyimo swa xikombelo na swintshuxo leswi endleriweke layini ya hina ya swikumiwa leswi heleleke ku katsa na lapi ra mahiselo ya le henhla ya PTFE, thepi yo namarhela ya mahiselo ya le henhla ya PTFE, bandi ra mesh ra mahiselo ya le henhla ya PTFE, bandi ra muchini wo fusa leri nga na swirhabyani, lapi leri funengetiweke hi tlhelo rin’we ra PTFE, bandi ra conveyor leri tiyiselaka mahiselo ya le henhla na ku tiya ka mahiselo ya le henhla lapi ra fiberglass, hi kombela u ntshunxeka ku hi tihlanganisa:
