Swikombiso swa Matirhelo ya Nkoka leswi faneleke ku Langutisisiwa Loko Ku Cheriwa Thepi ya Mahiselo ya le Henhla ya PTFE eka Vacuum Coating, Vacuum Heat Treatment na Tindhawu Tin’wana ta Vacuum

Jiangsu Aokai New Materials, muendli wa xiphurofexinali wa thepi ya mahiselo ya le henhla ya PTFE, u avelana nkongomiso wa xiphurofexinali. Loko yitirhisiwa eka vacuum coating, vacuum heat treatment na tindzhawu tin’wana ta vacuum, PTFE high-temperature tape yina swilaveko swa matirhelo ya nkoka leswi hambaneke swinene loko ku pimanyisiwa na switirhisiwa swa xibakabaka. Ku humesiwa ka gasi yale hansi, ku humesiwa ka volatile yale hansi xikan’we naku basa lokukulu i swilo swa nkoka swinene. Swikombiso swa nkoka leswi faneleke ku kamberiwa swi xaxametiwile hi ndlela leyi landzelaka:

1. Nhundzu ya Vacuum Outgassing (Xikombiso xa Nkoka swinene) .

Lexi i xikombiso xa matirhelo xa xiboho xa switirhisiwa swa vacuum. Ehansi ka ntshikelelo wale hansi na mahiselo yale henhla, thepi yita humesa gasi leyi khulukaka, leyi onhaka vacuum degree. Condensed volatiles yi thyakisa swiphemu swa optical, sputtering targets na workpieces, leswi endlaka leswaku kuva na foggy coatings, film adhesion yoka yingari kahle hambi kuri ku ala swihumelerisiwa hiku hetiseka.

· Ku Lahlekeriwa hi Nhlayo Hinkwayo (TML): Xilaveko xo angarhela TML ≤ 1.0%; switirhisiwa swa xiyimo xale henhla swofana na ti indasitiri ta aerospace na optical swilava TML ≤ 0.5%.

· Switirhisiwa leswi Hlengeletiweke leswi Pfuxetiwaka leswi Pfuxetiwaka (CVCM): Swi lawuriwa hi ndlela yo tika, hi ntolovelo CVCM ≤ 0.1%; swiyimo swa ultra-rigid swi lava CVCM ≤ 0.01%.

2. Giredi ya ku Tiyisela Mahiselo

· Mahiselo ya vukorhokeri lawa ya yaka emahlweni: Substrate ya fiberglass leyi funengetiweke hi PTFE ya thepi ya PTFE yinga tiyisela ku hlangana nkarhi woleha eka 260°C. Hambiswiritano, ku tiya ka mahiselo ya leyara yo namarhela swifanele ku tiyisisiwa hi nkarhi wun’we. Silicone PSA ya ntolovelo yinyika ku tiya loku yaka emahlweni ka kuhisa kwalomu ka 200°C, kasi silicone adhesive ya matirhelo yale henhla yinga fika eka 260°C.

· Mahiselo ya nhlohlorhi ya nkarhi wo koma: Languta loko mahiselo ya nhlohlorhi ya xihatla hi nkarhi wa ku lulamisiwa ya tlula mpimo wa mahiselo ya nkarhi wo koma wa thepi (hi ntolovelo ≤300°C). Ku hisa loku tlulaka mpimo kuta carbonize naku bola eka adhesive layer, leswinga endla leswaku kuva na thyaka swinene endzeni ka vacuum chamber. Xiya: Loko mahiselo ya vacuum heat treatment ya tlula swinene 260°C, PTFE tape ayi ha tirhi; thepi ya polyimide (Kapton) kumbe thepi ya aluminiyamu ya foil yi ta amukeriwa ematshan’wini ya sweswo.

3. Muxaka wa Xinamarheti & Matimba yo Khoma ya Mahiselo ya le Henhla

· Ku hlawuriwa ka sisiteme ya adhesive: Silicone pressure-sensitive adhesive i nhlawulo lowukulu eka switirhisiwa swa vacuum hikokwalaho ka ku tiya ka yona ka le henhla ka kuhisa. Hambi swi ri tano, swinamarheti leswi tolovelekeke swa silicone swi ni ti- siloxane to tala leti nga ni timolekhuli ta le hansi, leti khulukaka ehansi ka vacuum leyi nga ni mahiselo lamakulu naswona ti thyakisa swilo leswi tirhaka, ngopfu-ngopfu swilo leswi vonakaka ni tindhawu leti gezi ti hlanganaka eka tona. Hikokwalaho, ku laveka swivumbeko swo hlawuleka leswi basisiweke hi ndlela yo hlawuleka ya low-outgassing silicone adhesive kumbe non-silicone adhesive formulations.

· Matimba yo khoma ya mahiselo yale henhla: Ehansi ka swiyimo leswi hlanganisiweke swa vacuum na mahiselo yale henhla, creep, edge lifting kumbe full peeling ya thepi swita pfalela hiku kongoma tiphayiphi ta vacuum naku nghenisa swihlovo leswintshwa swa thyaka. Nkarhi wo khoma shear eka mahiselo yo tirha wufanele ku tiyisisiwa.

4. Ku basa & Ku Thyakisa hi Ionic

· Ku fambisana ka kamara ro basisa: Thepi yifanele kuva yingari na fibre shedding na lint eka matlhelo yo tsema. Tithepi leti endliwaka eka tindhawu to basa ta tsakeriwa.

· Nhlayo yale hansi ya ionic: Eka maendlelo ya vacuum eka ti indasitiri ta semiconductor na MEMS, ti halogen ions (Cl) na ti metal ions (Na, K) letinga eka thepi tita khuluka eka mahiselo yale henhla, ti corroding circuits kumbe ku cinca doping concentration. Kombela swiviko swa swikambelo swa ti ionic extractables kusuka eka vaphakeri.

· Zero silicone oil migration: Handle ka ti condensable volatiles, free silicone oil endzeni ka swinamarheti yinga rhendzeleka eka swiphemu naswona yivanga ku tsandzeka eka maendlelo ya bonding na welding lawa ya landzelaka. Boxa zero silicone oil migration grade eka switirhisiwa swa nkoka.

5. Matirhelo ya le Henhla ya Anti-Static

PTFE hi ntumbuluko i xitirhisiwa xa high-insulation. Static charge yi hlengeletana hiku olova ehenhla ka yona hiku hlangana kumbe ku rhurhumela endzeni ka ti vacuum chambers. Ku humesiwa ka gezi ku nga onha swiphemu swa elektroniki leswi nga ni vuxiyaxiya kumbe ku koka swilo leswi thyakeke leswi nga ni swiphemu-phemu.

· Xilaveko xa xikombiso: Eka ku sirhelela na nsirhelelo wa tindzhawu leti nga na vuxiyaxiya bya electrostatic, thepi ya anti-static PTFE ya laveka na surface resistivity kusuka eka 106 ~ 109 Ω/sq, naswona matirhelo yo tiya ya anti-static yafanele ku hlayisiwa endzhaku ka ku hlangana na mahiselo yale henhla.

6. Plasma & Ku lwisana na tikhemikhali

· Ku lwisana na plasma: Eka maendlelo ya sputtering na PECVD, thepi leyi nga hlangana na xibakabaka xa plasma yi ta etchiwa, ku humesa ti fluorine free radicals leti thyakisa tifilimi leti vekiweke na ku herisa ti vacuum chambers. Kambisisa ku tirhisiwa ka ha ri emahlweni, kutani u cincela eka thepi ya polyimide leyi nga ngheniwiki ngopfu hi plasma loko swi laveka.

· Ku lwisana na tikhemikhali: Nsinya wa oyili lowu saleke na swintshuxo swo basisa swi nga va kona hi nkarhi wa vutshunguri bya ku hisa ka vacuum; havumbirhi bya adhesive na substrate swita lwisana na ku pfimba na ku cinca ka tikhemikhali.

7. Ku tshamiseka ka Dimensional & Thermal Shrinkage Rate

Kuhunguteka ngopfu ka mahiselo eka mahiselo yale henhla swita paluxa matlhelo lawa yanga masked kutani swihumelerisa swirhumbana leswi namarhelaka, leswi onhaka ku kongoma ka masking xikan’we naku fambisana.

· Xilaveko xa xikombiso: Languta datha ya ku hunguteka ka mahiselo leyi nyikiweke hi vaendli (yi kamberiwile endzhaku ka 30 wa timinete eka 260°C). Premium vacuum-grade tape yi fikelela kuhunguteka ehansi ka 2% kumbe hambi kuri ehansi.

Nkatsakanyo wa Switsundzuxo swa Nhlawulo

Loko u xava thepi ya mahiselo yale henhla ya PTFE eka tindzhawu ta vacuum, ku lwisana na kuhisa ntsena aswi enelanga. Kombela swiviko swa xikambelo xa ku humesa gasi ya ASTM E595 ku suka eka vaphakeri, boxa kahle swiyimo swa vukorhokeri bya vacuum na ku lava tithepi to hlawuleka ta ku humesa gasi ya le hansi leti nga na xinamarheti xa silicone lexi basisiweke. Eka maendlelo ya nkoka ya vuhumelerisi, endla swikambelo swa tikhuphoni ta xikalo lexintsongo ku pima ku cinca cinca ka ntshikelelo wa xiphemu eka ti vacuum gauges naku kambela ku thyakisa loku nga vaka kona eka switirhisiwa leswi hetiweke.

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

Loko u lava ku kuma swihlawulekisi leswi nga na vuxokoxoko, swiyimo swa xikombelo na swintshuxo leswi endleriweke photifoliyo ya hina leyi heleleke ya swikumiwa 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 na swirhabyani, lapi ra PTFE ra tlhelo rin’we, bandi ro fambisa leri nga lwisaniki na mahiselo ya le henhla na fiberglass leyi tiyiselaka ku hisa lapi, hi kombela u hi tihlanganisa hi ku tirhisa vuxokoxoko lebyi nga laha hansi:
