Hi yihi rivilo ra layini leri tolovelekeke ra layini ya vuhumelerisi bya impregnation ya lapi ra mahiselo yale henhla ya PTFE?

I. Ndhawu ya Vulawuri bya Rivilo ra Layini leyi Tolovelekeke

Rivilo ra layini ra Layini ya vuhumelerisi bya PTFE ya mahiselo yale henhla ya fabric impregnation hi ntolovelo yi lawuriwa endzeni ka ndzhawu ya 2 kuya eka 15 m/min, laha nhlayo leyi tolovelekeke yo tirha leyi tiyeke yinga 3 kuya eka 8 m/min. Malapi yo olova kumbe milayeni yin’wana ya rivilo lerikulu yinga fika eka 10 kuya eka 15 m/min. Loko hi teka tani hi xikombiso xilaveko xa sintering xa 1.5 kuya eka 3 wa timinete xikan’we naku leha ka oven leyi tirhaka ya 20 wa timitara, rivilo ra theoretical line ringava kwalomu ka 6.7 kuya eka 13.3 m/min. Hiku tirhisa, margin ya vuhlayiseki yifanele ku hlayisiwa, laha rivilo ra xiviri hi ntolovelo ri vekiweke eka 60% kuya eka 80% wa ndzingano wale henhla, xisweswo hi ntolovelo ri tirha eka ndzhawu ya 4 kuya eka 10 m/min.

II. Swipimelo kusuka eka Impregnation Penetration na Maendlelo ya Coating

1. Nkarhi wo Chela na ku Nghena

Tani hilaha swi kombisiweke hakona hi muendli wa malapi ya mahiselo yale henhla ya Jiangsu PTFE: lapi ra fiberglass rifanele kuva ri tatiwe hiku hetiseka hi PTFE emulsion naswona ri nghena endzeni ka ti fibre bundles. Loko rivilo ra layini riri e henhla swinene, impregnation leyinga ringanelangiki ya humelela, hiku olova leswi endlaka leswaku kuva na ndlala ya resin yale ndzeni, ti fibre to oma, xikan’we naku kavanyetiwa ka adhesion na release properties. Viscosity ya emulsion, solids concentration, na weave density ya lapi (thick fabrics, tight weaves) hinkwaswo swihunguta penetration rate, leswivulaka leswaku malapi yo tiya na yo enta yafanele ku fambisiwa hi rivilo ro nonoka.

2. Ku enta ka Coating na Nhlayo ya ku Pasa ka Ku Cheriwa

Lapi ra mahiselo yale henhla hi ntolovelo rilava impregnation yotala na sintering passes (kwalomu ka 2 kuya eka 3 wa ti pass, minkarhi yin’wana kuya fika eka 6 kumbe kutlula). Leyara yin’wana na yin’wana yo peta yifanele kuva yitele leswaku kuta fikeleriwa ku peta lokunga na swihoxo. Ku hundza ko sungula ku endleriwe ku khoma lapi ra le hansi hi ku helela, hikwalaho rivilo hi ntolovelo ri nonoka; ku hundza loku landzelaka kunga engeteriwa hiku ringanela, kambe ku hundza kun’wana na kun’wana kufanele ku tiyisisa leveling leyi ringaneleke xikan’we naku sintering hiku hetiseka.

III. Swipimelo kusuka eka Ku Omisa, Ku Sinter, na Vuswikoti bya Switirhisiwa

1. Nkarhi wo tshama wa ku hisa na ku leha ka oveni

Lapi leri tsakamaka rifanele kuva ri omisiwa, ri sintering (eka 380–400°C kuva ri hlanganisa ti PTFE particles eka filimi), kutani ri titimela. Xiteji xa sintering hi ntolovelo xi lava makume ya tisekoni kuya eka timinete to hlaya. Rivilo ra layini ri ringana na ku leha ka oven loku tirhaka loku avanyisiweke hi nkarhi lowu lavekaka wa vutshunguri bya ku hisa. Loko ku leha ka oven ku tshamisekile, loko ku sintering swilava 2 wa timinete, rivilo ri pimiwile eka kwalomu ka 5 kuya eka 10 m/min. Rivilo leri tlulaka mpimo ri endla leswaku kunga sintering loku heleleke ka coating, ku basa, ku namarhela lokunga kahle, xikan’we naku endliwa ka ti pinholes nati bubbles.

2. Ku Fana ka Mahiselo na ku Famba-famba ka Moya wo Hisa

Ku famba famba kahle ka moya wo hisa xikan’we na mahiselo lawa ya fanaka ya oven swinga hungutela nkarhi wa vutshunguri bya kuhisa, leswi pfumelelaka rivilo ra layini hiku hatlisa. Hindlela yohambana, ku hangalasiwa ka mahiselo lokunga ringaniki kumbe kunga khuluki ka moya loku ringaneleke swilava rivilo ro nonoka kutiyisisa kufana ka coating eka ku anama ka lapi.

IV. Swipimelo ku suka eka Substrate, Emulsion, na Swilaveko swa Khwalithi yo Hetelela

1. Ku tiya ka Substrate, Ndzilo na ku anama

Malapi ya ultra-thin (xikombiso, 0.08 mm) yanga fambisiwa hi rivilo rale henhla ka 10 m/min, kasi malapi yo tiya ya 0.3 kuya eka 0.5 mm kumbe e henhla, xikan’we na malapi ya matimba yale henhla, ya high-density, ya lava rivilo ro nonoka (2 kuya eka 5 m/min) hikokwalaho ka ku hundziseriwa ka kuhisa hiku nonoka. Malapi ya ku anama yo anama yatala kuva ya transverse non-uniformity hinkarhi wa impregnation naku omisiwa, laha switala kuva swilava kuhungutiwa ka rivilo kutiyisisa kufana hiku angarhela.

2. Ku Endliwa ka Emulsion na Rheology

Ti impregnation liquids letingana solids yale henhla xikan’we na viscosity yale henhla tina ti penetration rates to nonoka, leswi lavaka rivilo rale hansi ra layini. Tinxaka na nhlayo ya ti wetting agents nati thickeners eka formulation swi khumba rivilo ro tsakamisa xikan’we na ti dehydration rates, leswi khumbhaka hiku kongoma rivilo lerikulu leri pfumeleriwaka ra layini.

3. Swilaveko swa Giredi ya Khwalithi ya Swikumiwa

Eka switirhisiwa leswi lavaka khwalithi yale henhla, kufana naku baka swakudya na malapi ya electronic soldering, swilaveko swaku hlayela ti pinhole, ku olova ka vuandlalo, na ku tiyisela ka vukulu swi tika swinene. Eka swiyimo swotani, rivilo ritala kuva ri nyikeriwa hi khwalithi, ku hlayisa rivilo ra layini eka xiyimo xale hansi kutiyisisa leswaku kuva na xifunengeto xo enta, lexinga na xihoxo xa zero.

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

Loko u lava ku dyondza swo tala hi swihlawulekisi swa vuxokoxoko, swiyimo swa xikombelo, na swihlawulekisi swa ku endla hi ku landza swilaveko swa 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, mabandhi ya mesh ya mahiselo ya le henhla ya Teflon, mabandhi ya muchini wo boha lama nga na swirhabyani, lapi ra PTFE ra tlhelo rin’we, mabandhi ya conveyor ya mahiselo ya le henhla, na ku tiyisela ku hisa malapi ya fiberglass – hi kombela u ntshunxeka ku hi tihlanganisa hi ku tirhisa leswi landzelaka:
