Tafula ra Swilo leswi nga endzeni

Eka swimilani swa tikhemikhali, tiphayiphi na swibya swi langutana na nhlaselo lowu tshamaka wuri kona kusuka eka swihangalasamahungu leswinga na matimba – ti acids to tiya, ti alkalis to hisa, ti organic solvents, na steam. PTFE tape i xitshunxo lexi tolovelekeke xa nsirhelelo wa anti-corrosion, non-stick, na ku pfalela. Kambe ku hlawula thepi leyinene a swi olovi ku fana ni ku hlawula mpimo wa le henhla wa mahiselo.

Aokai PTFE yi phakerile thepi ya PTFE eka switirhisiwa swa tikhemikhali ku ringana makume ya malembe. Nkongomiso lowu wu hlamusela xivumbeko xa swiphemu swinharhu swa thepi ya PTFE, swipimelo swa ku hlawula swa nkoka (mahiselo, swihangalasamahungu swa tikhemikhali, swilaveko swa michini), na swiletelo swa nkoka swo aka.

Xivumbeko xa Tilayeri Tinharhu xa Thepi ya Mahiselo ya le Henhla ya PTFE

Ku tirha hinkwako ka thepi ya PTFE ya mabindzu ya vekiwa hi swiphemu swinharhu swa xivumbeko:

Leyara ya Xivumbeko	Switirhisiwa Leswi Tolovelekeke	Vuyelo eka Nhlawulo wa Swikumiwa
Leyara ya ntirho wa le henhla	Filimi ya PTFE yo basa / lapi ra fiberglass leri cheriweke PTFE	Yi lawula nhundzu leyi nga namarheliki, ku tiya ka tikhemikhali, na ku tiya lokukulu ka mahiselo
Ku tiyisisa substrate	Ku hava (filimi yo basa) / Lapi ra fiberglass / Lapi ra Aramid	Ku kumisisa matimba ya michini, ku tiya ka ku tsana, na ku tiya ka ku tlhaviwa
Leyara yo namarhela	Silicone PSA, Acrylic PSA, PSA leyi simekiweke eka rhaba	Ku veka mpimo wa le henhla wa mahiselo na ku tiya ka tikhemikhali ta thepi hinkwayo; hi ntolovelo i xihlanganisi xa matirhelo lexi tsaneke swinene

Vutivi bya nkoka: Hambileswi PTFE hi yoxe yi nga tirhaka hi ndlela leyi tiyeke ku suka eka -190°C ku ya eka 260°C nkarhi wo leha, xinamarheti i xisirhelelo xa matirhelo . Hlawula xinamarheti hi ku ya hi ndhawu ya xiviri ya vukorhokeri, ku nga ri ntsena vuandlalo bya PTFE.

Swipimelo swa Nkoka swa Nhlawulo na Misinya ya Misinya ya ku Fambisana

1. Mahiselo yo tirha – ku hlawuriwa ka adhesive i nchumu wa nkoka swinene

Ndzhawu ya Mahiselo	Xinamarheti lexi Bumabumeriwaka	Hikokwalaho ka yini
200°C – 260°C (ya nkarhi woleha) .	Silicone PSA (ya laveka) .	Endlelo ro namarhela ntsena leri hlayisaka tackiness leyi tiyeke eka range leyi; masalela matsongo endzhaku ko rhurhumela
120°C – 180°C na ku tiya ka solvent & oil yale henhla	PSA ya acrylic ya mahiselo yale henhla	Ku boha loku tiyeke kutlula silicone, kambe ku tsandzeka hiku hatlisa eka 260°C
Ehansi ka 100°C	Acrylic leyi tolovelekeke kumbe leyi endliweke hi rhaba	Swi amukeleka, kambe a swi talanga eka tindhawu ta tikhemikhali

Aokai PTFE note: Eka switirhisiwa eka 200°C+, acrylic PSA ayi amukeleki – yita onha, yi olovisa, naswona yivanga ku rhurhumela ka tape. Silicone hi yona ntsena leyi nga hlawuriwa.

2. Swihangalasamahungu swa tikhemikhali – ku fambisana exikarhi ka xinamarheti na substrate

Leyara ya ntirho ya PTFE yi na ku lwisana na ku bola ka kwalomu ka hinkwako (handle ka tinsimbi ta alkali leti n’okiweke na gasi ya fluorine ya ntshikelelo wa le henhla wa mahiselo yale henhla). Hambiswiritano, swihaxa-mahungu swa tikhemikhali swi nghena kusuka emakumu ka thepi naswona swi khuluka hi ku kongoma leyara leyi namarhelaka.

Vuhangalasi bya Mahungu bya Tikhemikhali	Xinamarheti lexi Bumabumeriwaka	Lemukisa
Ti acid to tiya leti nga riki ta ntumbuluko (HCl, H2SO4 ≤80%), ti alkali to tiya (NaOH), brine, mpfula ya mati	Silicone PSA ya xirhendzevutani	Ku tiyisela lokunene ngopfu; yi vumba cladding yo sirhelela leyi tiyeke
Ti solvents ta organic (ketones, esters, benzene, toluene), mafurha, mafurha, ti oxidizing acids to tiya (HNO3, concentrated H2SO4), glacial acetic acid	Acrylic PSA (giredi leyi nga ngheniwiki hi solvent) .	Silicone yi pfimba eka swintshuxo swa organic; acrylic ya hlohleteriwa, kambe tiyisisa mpimo wa mahiselo (hi ntolovelo ≤150°C) .
Musi wa mahiselo yale henhla + acid/alkali ya nhlayo yale henhla (ku hlangana loku cincaka) .	Silicone PSA leyi cinciweke + ku rhendzeleka ka swiphemu swo tala	Xiyimo xo tika swinene – silicone yinga hydrolyze; tiyisisa hi ku rhendzeleka ka swiphemu swo tala

Eka mahiselo lawa ya tlulaka 150°C na ti organic solvents: Tirhisa mechanical fixing kumbe glue-free heat-shrink pure PTFE tape/tubing.

Swiendlakalo swa Xitirhisiwa na Nhlawulo wa Substrate lowu Fambelanaka

Xiendlakalo xa Xikombelo	Substrate leyi ringanyetiweke	Xivangelo
Pipe outer wall anti-corrosion & anti-stick coating (ku sivela ku hlengeletiwa ka swilo swa splash)	Lapi ra fiberglass leri funengetiweke hi PTFE leri nga ni matimba swinene (ya buraweni/wa ntima) .	Ku nga onhaki, ku nga handzuki; ku enta ka 0.13-0.25mm; swi lulamerile ku phindha-phindha ku rhendzeleka, ku fambisana kahle swinene
Xibya xa le ndzeni xa rirhangu & flange surface anti-stick liner	Filimi ya PTFE yo basa leyi nga erivaleni	Ultra-smooth non-stick surface, ku hava khombo ro wicking fibre; swikahle eka swiphemu leswinga flat na leswikulu leswi govekeke
Ku hlanganisa shaft & ku phutsela hi roller	Lapi ra fiberglass ra PTFE leri nga na xinamarheti xa silicone xa high-tack	Ku seketela ku rhendzeleka ka tension; fiberglass substrate yi tisa matimba yale henhla ya tensile, yi papalata deformation hinkarhi wa ku rhendzeleka
Ku pfariwa ka thyaka na ku cinciwa ka gasket	Thepi ya filimi ya PTFE yo basa leyi endliweke hi muchini	Tirhisa nhundzu ya PTFE cold flow ku tata swivandla; Thepi leyi nga riki na fiberglass ya laveka
Manholes & sight glasses ta mathangi yo hlayisa acid yo tiya	Pure PTFE film / fiberglass fabric leyi nga na xinamarheti xa acrylic lexi nga ngheniwiki hi tikhemikhali	Filimi yo basa yi hambanisa swihaxa-mahungu leswi onhaka; lapi ra fiberglass ri antswisa ku tiya; ti lap joints ti lava ku tiyisisiwa ka ti multi-layer

Swiletelo swa Nkoka swa ku Aka na Vuhlayiseki

1. Surface pretreatment – masungulo ya ku boha

Ku susiwa mafurha hi ku helela, ku susa rust ni ku omisa swa laveka. Sula swiphemu hi acetone kumbe byala kutani u landzeriwa hiku hatlisa hiku baka hi malangavi kuva u andzisa matimba ya bonding. Leswi swi susa swilo leswi thyakeke naswona swi endla leswaku nsimbi yi tirha leswaku yi namarhela swinene.

2. Ku hlanganisa na ku rhendzeleka ka swiphemu

Ku laveka 2-3 wa ti winding layers eka nsirhelelo wa ti khemikhali laha kungana 50% wa ku hlangana hi xirhendzevutani. Makumu ya thepi yafanele ku tiyisisiwa hi thepi ya PTFE leyi fambelanaka kumbe ti cable ties ta stainless steel ku sivela ku rhurhumela loku heleleke endzhaku ka ku nghena ka adhesive hi media.

3. Safety threshold – loko u fanele ku papalata thepi ya PTFE hi ku helela

Eka swihangalasamahungu leswi landzelaka swo tlula mpimo, tithepi hinkwato leti nga na swinamarheti swa organic a ti hlayisekanga :

Xigwitsirisi xa hayidirojeni (HF) .
Ku virisa alkali yo tiya ya nhlayo yale henhla (>80%) .
Kloroni ya trifluoride (ClF3) .

Ndlela yin’wana: Cinca kuya eka full PTFE lining kumbe welded fixed cladding (ku hava xinamarheti).

4. Magoza yo lwisana na static na ku nga buluka

Loko phayiphi yi hundzisela switirhisiwa leswi pfurhaka naswona ku hlengeletiwa ka static kunga humelela, hlawula anti-static PTFE tape (hi ntolovelo ya ntima ya ntima na carbon filler, surface resistivity 106-109 Ω) ku hangalasa static charge hiku hlayiseka.

Nkatsakanyo – Nkongomiso wa Xihatla wa ku Hlawula Thepi ya PTFE eka Switirhisiwa swa Tikhemikhali

Loko ndhawu ya wena yi ri...	Hlawula...	Papalata...

Aokai PTFE yinyika nxaxamelo hinkwawo wa tithepi ta PTFE eka switirhisiwa swa tikhemikhali – silicone PSA eka vukorhokeri bya high-temp acid/alkali, acrylic PSA eka ku lwisana na solvent, na ti anti-static grades. Tihlanganise na hina hi swihangalasamahungu swa wena swa tikhemikhali, mpimo wa mahiselo, na swilaveko swa michini eka nhlawulo lowu lulamisiweke.

Vuxokoxoko bya xithekiniki lebyi nga laha henhla byi nyikiwa hi Jiangsu Aokai Switirhisiwa Leswintshwa Thekinoloji Co., Ltd.

Loko u lava swihlawulekisi swa vuxokoxoko, timhaka ta xikombelo na swintshuxo leswi endleriweke ku tirhisiwa ka switirhisiwa swa hina hinkwaswo 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 ro kandziyisa ku hisa leri nga riki na swirhabyani, lapi ra PTFE ra tlhelo rin’we, bandi ro fambisa leri nga na mahiselo ya le henhla na lapi ra fiberglass leri tiyiselaka ku hisa, hi kombela u tihlanganisa hina hi ku tirhisa tichannel leti nga laha hansi:
