PTFE high-temperature fabric ( PTFE-coated fiberglass ) yitiveka hiku lwisana na kuhisa, swivumbeko leswinga namarheli, na ku nga tirhi ka tikhemikhali. Kambe kahle-kahle yi teka nkarhi wo tanihi kwihi? Nhlamulo ayi olovi – yihambana kusuka eka tinhweti nyana kuya eka malembe yo hlaya, kuya hiku hetiseka eka swiyimo swa ntirho xikan’we na leswaku yi hlayisiwa kahle kufikela kwihi.
Aokai PTFE yi phakerile lapi ra PTFE eka switirhisiwa leswi nga hlayekiki. Laha hansi hi hlamusela swilo swo angarhela leswi khumbhaka vutomi eka xiyimo xin’wana na xin’wana, kutani hi nyika ku languteriwa ka vutomi bya xiviri eka switirhisiwa swa tsevu leswi tolovelekeke – kusuka eka ku baka swakudya kuya eka ti khemikhali ta anti-corrosion.
Loko unga se languta switirhisiwa swokarhi, twisisa swilo swa misava hinkwayo leswi pfuxetaka kumbe ku engetela vutomi bya lapi ra PTFE.
1. Ku lawula mahiselo i swa nkoka swinene
Nhlayo ya mahiselo ya nkarhi woleha ya ntirho i -70°C kuya eka 260°C . Ku famba ko koma kuya eka 350°C swa koteka, kambe ku hisa ngopfu swi onha xivumbeko xa swilo naswona swihunguta vutomi swinene.
Data ya xikambelo: Nchumu lowu wu hlayisa matirhelo lawa yanga onhakiki endzhaku ka ku tshamela ku hlangana eka 250°C kuringana 200 wa masiku.
Nawu wa xihatla: Eka 10°C yin’wana na yin’wana ehenhla ka 260°C, mpimo wa ku onhaka wu kwalomu ka kambirhi. Hlayisa u ri endzeni ka swipimelo.
2. Papalata ku onhaka ka miri – ti sharp creases i nala
Sivela swirhendzevutani leswi tlhavaka hi nkarhi wa ku vekiwa na ku tirha. Ti creases ti endla tindzhawu ta stress concentration naswona tinga vanga ku handzuka hiku olova – ngopfu ngopfu loko titirhisiwa tani hi conveyor belts. Loko se kuvumbiwa crease line, fiberglass substrate ya tshoveka ehansi, naswona coating ya pandzeka.
3. Ku hlangana na tikhemikhali na ku thyakisa
PTFE yi lwisana na ti acid to tiya na ti alkali kahle swinene. Hambiswiritano, ku hlangana nkarhi wo leha na swivati swa mafurha, swinamarheti swa hot melt kumbe ti pigments eka mahiselo yale henhla swinga hatlisisa ku dyuhala ka coating. Hambi leswi PTFE yinga tirhiki, swilo leswinga sala swinga carbonize ehenhla naswona swi onha swivumbeko swa release.
4. Ku lwisana na ku onhaka ka michini
Ku hlangana loku yaka emahlweni na tension swi onha ehansi ka xifunengeto xa le henhla. Hlayisa lapi ekule na swilo leswi karihaka. Eka switirhisiwa swo rhetela, ehleketa hi tigiredi ta PTFE leti tatiweke kumbe ku cheriwa ka mafurha ya nkarhi na nkarhi.
5. Ku kamberiwa nkarhi na nkarhi na ku cinca
Endla vuhlayiseki bya ntolovelo na ku kambela endzhaku ka tinhweti tin’wana na tin’wana tinharhu ku kuma matirhelo lama tiyeke. Eka milayeni ya nkoka ya vuhumelerisi, lunghiselela sete ya xiphemu leswaku yita tirhisiwa hiku cincana. Ku kumiwa ka ku onhaka ka ha ri na nkarhi swi sivela ku tsandzeka lokukulu.
Ku pimanisiwa ka Vutomi bya Vukorhokeri bya Swiendlakalo swa Tsevu swa Xikombelo leswi Tolovelekeke
Tafula leri landzelaka ri katsakanya vutomi bya vukorhokeri lebyi languteriweke lebyi simekiweke eka datha ya nsimu ya misava ya xiviri ku suka eka vaxavi va Aokai PTFE .
Xiendlakalo xa Xikombelo
Swiyimo swa Ntirho & Ntshikelelo
Vutomi Bya Vutirheli Lebyi Languteriweke
Ku Baka Swakudya
Ku hisa ≤260°C; ku hlangana na mafurha; excellent non-stick, swa olova ku swi basisa
Ku leha – Switirhisiwa swa static (baking trays) switshama tinhweti to hlaya laha kungana kwalomu ka ku onhaka
Ti-Conveyor Belts ta le ka tiindasitiri
200-260°C ya xiyimo xa le henhla; ku hlangana loku yaka emahlweni ka swilo ni ku tsana ka michini
Ku ringanela – Ku tsandzeka ngopfu ngopfu kusuka eka ku onhaka na ku pandzeka; hi ntolovelo 6-18 wa tinhweti kuya hi ntirho
Ku Pfala Hi Ku Hisisa & Ku Welda
Ku hisa ka nkarhi na nkarhi 200-300°C; ku tshamela ku hlangana na tinhloko to pfalela
Ku leha swinene – Yitshama yiri yintshwa endzhaku ka 7 wa swirhendzevutani eka 190°C ya nkarhi wo koma ya ku tshikileriwa hi ku hisa. Ku peeling ka coating i khombo lerikulu
Tikhemikhali Anti-corrosion
Ti acid ta matimba, ti alkali, swintshuxo swa organic; yin’wana ehansi ka mati kumbe ku kufumela lokukulu
Ku leha swinene – Mhaka leyi tirhaka: pipeline cladding yi tirhile kuringana 3 wa malembe ehansi ka 320°C steam; desulfurization tower lining eka acid yo tiya yitshame yiri kona kuringana 3 wa malembe – 4x yo leha kutlula switirhisiwa swa rhaba
PV Lamination ya PV
~150°C ehansi ka ntshikelelo wa le henhla; ku tshamela ku hlangana na xisirhelelo xa EVA lexi n’okiweke
Ku ringanela – Residual adhesive xikan’we naku phindha-phindha ku tshikileriwa hi ku hisa i swivangelo leswikulu swa ku tsandzeka; hi ntolovelo 6-12 wa tinhweti
Switirhisiwa swa Friction swa ntirho wo tika
Ku khumbana hiku kongoma na ti abrasives (xikombiso, substrate ya ti abrasive cutting discs) .
Short – Ku rhurhumela lokukulu swi pfuxeta vutomi swinene; yi hambana hi ku tiya ka abrasive na rivilo; swi nga ha teka mavhiki kumbe tin’hweti
Ndlela Yo Kurisa Vutomi Bya Vutirheli – Switsundzuxo Leswi Tirhaka
1. Ku hlawuriwa loku faneleke ka swikumiwa
Hlawula ku enta loku faneleke, ku luka, na ku peta eka xitirhisiwa xa wena xo karhi. Eka switirhisiwa swa high-wear, hlawula PTFE grade leyi tatiweke kumbe lapi ro tiya. Eka ku hlangana na ti khemikhali, tiyisisa leswaku ku cheriwa hiku hetiseka naswona kungari na ti pinholes.
2. Ku vekiwa loku ringaniseriweke
Papalata ku tsana ngopfu loko u nghenisa mabandhi yo fambisa.
Tirhisa roller diameter leyikulu swinene ku hunguta ntshikelelo wa ku gombonyoka.
Pfala makumu hi silicone sealant eka tindzhawu letingana ndzhongho.
3. Ku hlayisa nkarhi na nkarhi
Hlantswa lapi nkarhi na nkarhi ku sivela ku hlengeletana ka masalela.
Hlayisa lapi ri ri flat naswona ri nga ri na swirhumbana loko ri ri karhi ri tirha.
4. Ku cinca hi nkarhi – tiva swikombiso swa xilemukiso
Cinca lapi hi ku hatlisa loko u xiya:
Ku cinca ka muhlovo swinene (ku tshwuka, ku va buraweni, ku va ntima) .
Ku tshoveka (ku pandzeka ka lapi loko ri govekile) .
Ku peta swirhumbana kumbe ku rhurhumela ka ndzhawu leyikulu
Ku vonakala ka edge fraying kumbe ti holes
U nga yimeli xirhendzevutana lexi hleriweke xa ku cinca loko swikombiso leswi swi humelela. Lapi leri onhakeke ri nga thyakisa swilo leswi endliweke kutani ri onha switirhisiwa.

Ku teka ko hetelela: Lapi ra mahiselo yale henhla ya PTFE i xitirhisiwa xa matirhelo yale henhla, kambe vutomi bya rona bya xiviri bya ntirho byi titshege ngopfu hi ndlela leyi byi tirhisiwaka ha yona. Ku lawula mahiselo hi ndlela yo tika (tshama ≤260°C), papalata swirhumbana leswi tlhavaka, basisa nkarhi na nkarhi, naswona u cinca eka xikombiso xosungula xa ku pfimba kumbe ku tshwuka. Eka switirhisiwa leswi lavaka kufana na ti khemikhali ta anti-corrosion, lapi ra PTFE ringa hanya kutlula switirhisiwa swa ndzhavuko hi malembe.
Aokai PTFE yi nyika nseketelo wa xithekiniki ku ku pfuna ku hlawula lapi leri faneleke na ku kurisa vutomi bya rona. Tihlanganise na hina hi vuxokoxoko bya xikombelo xa wena.
Hi nyika nxaxamelo hinkwawo wa switirhisiwa ku katsa na malapi ya mahiselo ya le henhla ya PTFE, tithepi ta mahiselo ya le henhla ya PTFE, mabandhi ya mesh ya PTFE, mabandhi lama nga na swirhabyani ya michini yo boha, malapi ya PTFE ya tlhelo rin’we, mabandhi ya conveyor lama nga tiyiseliki mahiselo ya le henhla na malapi ya fiberglass. Titwele u ntshunxekile ku hi tihlanganisa ku kuma vuxokoxoko bya tipharamitha ta swikumiwa, nkongomiso wa xitirhisiwa na swintshuxo leswi endleriweke wena.
Hi namarhela filosofi ya vutshila na vutshembeki, naswona hi tinyiketerile ku nyika swintshuxo swa xiyimo xin’we na vukorhokeri lebyi ehleketiweke eka vaxavi hinkwavo.
