PTFE Tape Salt Spray Resistance & Swilaveko swa ku cheriwa ka le lwandle

Thepi ya mahiselo yale henhla ya PTFE yitirhisiwa ngopfu eka tindzhawu tale lwandle – eka tipulatifomo ta le lwandle, swikepe, tithavhinini ta moya ta le ribuweni, na tindzhawu ta tiindasitiri leti taleke hi munyu. Xifunengeto xa PTFE hi xoxe xi lwisana swinene na ku fafazeriwa ka munyu. Hambiswiritano, matirhelo hinkwawo ya thepi ya titshege hi tindzhawu timbirhi leti tsaneke: leyara yo namarhela na makumu ya substrate ya fiberglass.

Salt spray yinga nghena hiku tirhisa ti adhesive interfaces kutani yi wick eka matlhelo ya fiberglass lawa yanga erivaleni, leswi endlaka leswaku kuva na ku lahlekeriwa hi adhesion kumbe substrate corrosion. Hikokwalaho, ku kambela ku lwisana na ku fafazeriwa ka munyu swivula ku kambela loko xinamarheti xi hlayisa matimba yo boha, xi lwisana na ku tswongiwa ka mati naswona xi sirhelela nsimbi leyi nga ehansi.

Aokai PTFE yi endla thepi ya PTFE leyi tiyisisiweke eka vukorhokeri bya le lwandle. Nkongomiso lowu wu hlamusela tindlela ta ntolovelo ta xikambelo, swipimelo swo amukela, na swilaveko swa ku tirhisiwa eka tindhawu leti nga na nkungu wa munyu wo tala.

Tindlela ta Xikambelo xa ku Fafazela Munyu ta Thepi ya PTFE

Ku kamberiwa loku ringaniseriweke ku tiyisisa leswaku thepi yi hlangana na ku tiya ka xiyimo xa le lwandle. Ndlela leyi tolovelekeke swinene i neutral salt spray (NSS) hi ISO 9227 kumbe ASTM B117.

1. Ku lulamisiwa ka xikombiso

1. Laminate thepi ya PTFE eka phanele ya xikambelo xa nsimbi ya ntolovelo (xikombiso, SUS304 stainless steel kumbe substrate leyi kunguhatiweke) hiku tirhisa roller.

2. Pfala makumu ya tape hi sealant leyi nga ngheniwiki hi mati ku sivela ku nghena ka nkungu wa munyu lowu nga tolovelekangiki kusuka eka matlhelo lawa ya tsemiweke. Leswi swi tekelela ku vekiwa loku faneleke laha makumu ya sirhelelekeke.

3. Lulamisa swikombiso leswi ringaneleke eka mintlawa ya pre-test, post-test, na control.

2. Ku hlangana na nkungu wa munyu

• Veka swikombiso eka kamara ro fafazela munyu eka 35°C, 5% NaCl solution.

• Minkarhi ya swikambelo: 96h, 240h, 500h, 1000h , kumbe hilaha ku pfumelelaniweke hakona.

• Tilt test panels eka 15°–30° kusuka eka vertical kuva yiva na ku vekiwa ka nkungu wa munyu hambi kuri.

3. Ku kamberiwa endzhaku ko hlangana na swona (hlamba na ku omisa) .

Swilaveko swa Xikombelo eka Tindhawu ta le Lwandle & ta High-Salt-Fog

Eka ku tirhisiwa ka xiviri eka tipulatifomo ta le lwandle, swikepe, switirhisiwa swa gezi ra moya ra le ribuweni, na tindhawu ta tiindasitiri leti nga na nkungu wa munyu wo tala, thepi ya PTFE yi fanele ku fikelela swipimelo swo tika.

1. Xinamarheti – silicone PSA ya boha

• Silicone pressure-sensitive adhesive: Ultra-low moisture absorption, ku lwisana swinene na nkungu wa munyu, ku olova ka maxelo. Yi hlayisa matimba yo boha ya nkarhi woleha naswona ayi onhi nsimbi leyinga tshukatshukiki.

• Acrylic PSA – A YI ringanelanga: Yi hydrolyze hiku olova, yi plasticize, naswona yi lahlekeriwa hi ku namarhela ehansi ka mahiselo yale henhla xikan’we na nkungu wo tika wa munyu. Acrylic ayi fanelanga kuva yitirhisiwa eka tindzhawu tale lwandle.

2. Nsirhelelo wa substrate na makumu

• Lapi ra fiberglass rifanele ku cheriwa hiku hetiseka hi PTFE , kungari na ti pinholes. Leswi swi sivela ku nghena ka munyu hiku tirhisa capillary action etlhelo ka ti fibre, leswinga vanga delamination.

• Hi nkarhi wa ku vekiwa, seal tape overlaps na makumu hi sealant leyi tinyiketeleke leyi nga lwisaniki na maxelo (xikombiso, silicone-based). Leswi swi sivela tindlela to nghena eka nkungu wa munyu – goza ra nkoka swinene eka ku tshembheka ka nkarhi woleha.

3. Ti indices leti ringanyetiweke ta ku lwisana na ku fafazeriwa ka munyu

• Minimum 1000h neutral salt spray (NSS) handle ko tlakuka hiku tisungulela kumbe ku pfimba.

• 180° ku khomiwa ka matimba ya peel ≥80% endzhaku ka 1000h.

• Ku hava ku bola eka nsimbi leyi nga ehansi (kumbe swikombiso swa ku bola endzeni ka swipimelo leswi ku pfumelelaniweke ha swona).

• Eka swiyimo swo tika swinene (xikombiso, ti marine atmospheric zones letingana wet-dry cycles), 2000h NSS kumbe cyclic corrosion testing (CCT) swa hlohleteriwa.

4. Ku pfumelelana na tindhawu leti hlanganisiweke

• Mahiselo yale henhla + nkungu wa munyu: Eka ku phutsela tiphayiphi ta exhaust kumbe heat-tracing cable insulation, endla swikambelo leswi hlanganisiweke swa ku dyuhala (ku hisa lokukulu + ku fafazela munyu).

• Ku hlangana na UV: Ku tirhisiwa ehandle ka lwandle swilava ku lwisana na UV – adhesive ayi fanelanga ku chalk kumbe ku debond ehansi ka ultraviolet radiation.

5. Ku vekiwa na ku hlayisa

• Ku lulamisiwa ka vuandlalo: Degrease hiku hetiseka na derust bonding surfaces. Matching primer ya hlohleteriwa kuva yi ndlandlamuxa interfacial bonding xikan’we naku sivela ku nghenelela ka salt fog.

• Ku kambela nkarhi na nkarhi: Languta makumu ya thepi hi nkarhi wa vukorhokeri ku vona loko ku ri na swirhumbana kumbe ku rhurhumela. Cinca thepi leyi tsandzekeke hiku hatlisa ku sivela crevice corrosion ya xivumbeko lexi bohiweke.

Nkatsakanyo – Swilo swa nkoka swa Thepi ya PTFE ya Giredi ya le Lwandle

Aokai PTFE yinyika thepi ya mahiselo yale henhla ya PTFE leyi tiyisisiweke eka tindzhawu tale lwandle na letingana nkungu wa munyu wale henhla. Xivumbeko xa hina xa silicone PSA xi hundze eka 1000h NSS testing na >85% wa ku khomiwa ka matimba ya peel. Hi tlhela hi nyika switsundzuxo swa primer na edge sealant. Tihlanganisi na hina ku kuma swiviko swa swikambelo na nkongomiso wa xikombelo.

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

Loko u lava ku dyondza swo tala hi vuxokoxoko bya swihlawulekisi, swiyimo swa xikombelo na swintshuxo leswi endleriweke nxaxamelo wa hina hinkwawo wa swikumiwa, 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 ya muchini wo boha lama nga na swirhabyani, lapi ra PTFE ra tlhelo rin’we, mabandhi ya conveyor lama nga tiyangiki na mahiselo ya le henhla na fiberglass leyi nga tiyangiki hi mahiselo ya le henhla malapi, hi kombela u hi tihlanganisa:

• Nkulukumba Guo: +86 18944819998

• Nkulukumba Liu: +86 13705266308

Minkarhi hinkwayo hi namarhela filosofi ya vutshila na vutshembeki, naswona hi tiyimiserile ku ku nyika swintshuxo swa xiyimo xin’we na vukorhokeri lebyi ehleketiweke.
