Zizindikiro Zogwirira Ntchito Zomwe Muyenera Kuziganizira Mukayika Tepi ya PTFE Yotentha Kwambiri mu Vacuum Coating, Chithandizo cha Kutentha kwa Vacuum ndi Malo Ena Opuma

Jiangsu Aokai New Materials, katswiri wopanga tepi yotentha kwambiri ya PTFE, amagawana upangiri waukadaulo. Akagwiritsidwa ntchito popaka vacuum, chithandizo cha kutentha kwa vacuum ndi malo ena opanda mpweya, tepi ya PTFE yotentha kwambiri imakhala ndi zofunikira zosiyana kwambiri ndi zomwe zimachitika mumlengalenga. Kutulutsa mpweya pang'ono, mpweya wochepa kwambiri komanso ukhondo wambiri ndizo zofunika kwambiri. Zizindikiro zazikulu zomwe ziyenera kuyesedwa zandandalikidwa motere:

1. Katundu Wotulutsa mpweya (Chizindikiro Chovuta Kwambiri)

Uwu ndiye mlozera wotsimikizika wa magwiridwe antchito a vacuum. Pansi pa kupanikizika kochepa komanso kutentha kwakukulu, tepiyo idzatulutsa mpweya wosasunthika, womwe umasokoneza digiri ya vacuum. Ma volatiles ofupikitsidwa amawononga zinthu zowoneka bwino, zowongoka ndi zogwirira ntchito, zomwe zimapangitsa kuti pakhale chifunga, kusamata bwino kwamakanema komanso kukana kwathunthu kwazinthu.

· Kutaya Kwambiri Kwambiri (TML): Zofunikira zonse TML ≤ 1.0%; ntchito zapamwamba kwambiri monga zamlengalenga ndi mafakitale opanga kuwala zimafuna TML ≤ 0.5%.

· Zosonkhanitsidwa Zowonongeka Zowonongeka (CVCM): Zoyendetsedwa bwino, kawirikawiri CVCM ≤ 0.1%; Zochitika zolimba kwambiri zimafuna CVCM ≤ 0.01%.

2. Kutentha Kukaniza kalasi

· Kutentha kosalekeza kwautumiki: Gawo la PTFE-lokutidwa ndi fiberglass la PTFE la tepi la PTFE limatha kupirira kuwonetseredwa kwanthawi yayitali pa 260°C. Komabe, kukana kutentha kwa zomatira kuyenera kutsimikiziridwa nthawi imodzi. Silicone PSA wamba imapereka kukana kutentha kosalekeza mozungulira 200 ° C, pomwe zomatira za silicone zowoneka bwino zimatha kufikira 260 ° C.

· Kutentha kwanthawi yayitali: Onani ngati kutentha kwanthawi yayitali panthawi yokonza kupitilira malire anthawi yayitali a tepi (nthawi zambiri ≤300 ° C). Kutentha kochulukirapo kumawononga mpweya ndikuwola zomatira, zomwe zimapangitsa kuipitsidwa kwambiri mkati mwa chipinda chopumuliramo. Zindikirani: Ngati kutentha kwa vacuum kutentha kumaposa 260 ° C, tepi ya PTFE sikugwiranso ntchito; tepi ya polyimide (Kapton) kapena tepi ya aluminiyamu yojambulayo iyenera kutengedwa m'malo mwake.

3. Mtundu Womatira & Mphamvu Yogwira Kutentha Kwambiri

· Kusankha kwa makina omatira: Zomatira zotengera kukakamiza kwa silicone ndiye chisankho chachikulu pakugwiritsa ntchito vacuum chifukwa cha kukana kwake kutentha kwambiri. Komabe, zomatira wamba za silikoni zimakhala ndi ma siloxane ambiri otsika kwambiri, omwe amasinthasintha pansi pa vacuum yotentha kwambiri ndikuyipitsa zogwirira ntchito, makamaka malo owoneka bwino ndi malo olumikizirana ndi magetsi. Chifukwa chake, zomatira za silicone zoyeretsedwa mwapadera zotulutsa mpweya kapena zomatira zopanda silicon ndizofunikira.

· Mphamvu yogwira yotentha kwambiri: Pamalo ophatikizika a vacuum ndi kutentha kwambiri, kukwawa, kukweza m'mphepete kapena kusenda kwathunthu kwa tepiyo kumatsekereza mapaipi a vacuum ndikuyambitsa zotengera zatsopano. Kutalika kwa kumeta ubweya wa ubweya pa kutentha kwa ntchito kuyenera kutsimikiziridwa.

4. Ukhondo & Kuwonongeka kwa Ionic

Kugwirizana kwa chipinda choyeretsera: Tepiyo idzakhala yopanda ulusi wothira komanso ulusi m'mphepete. Matepi opangidwa m'zipinda zoyeretsera amawakonda.

· Zochepa za ayoni: Pazinthu za vacuum mu semiconductor ndi mafakitale a MEMS, ma ion halogen (Cl) ndi ayoni achitsulo (Na, K) omwe ali mu tepi amatsika kutentha kwambiri, ma corroding circuits kapena kusintha doping concentration. Funsani malipoti oyeserera a ionic kuchokera kwa ogulitsa.

Kusamuka kwamafuta a silicone a Zero : Kupatula kusinthasintha kwamphamvu, mafuta a silicone aulere mkati mwa zomatira amatha kuyandama ndikupangitsa kulephera kumangirira ndi kuwotcherera. Tchulani kalasi ya zero silicone yosuntha mafuta pazofunikira kwambiri.

5. Pamwamba Anti-Static Magwiridwe

PTFE mwachibadwa ndi zinthu zoteteza kwambiri. Static charge imadziunjikira pamwamba pake chifukwa cha kukangana kapena kusenda mkati mwa zipinda zotsekera. Electrostatic discharge imatha kuwononga zida zamagetsi kapena kukopa zowononga.

· Chofunikira pazizindikiritso: Kuti muteteze ndi kuteteza madera okhudzidwa ndi ma electrostatic-sensitive, tepi ya anti-static PTFE imafunika yokhala ndi mphamvu yolimbana ndi pamwamba kuyambira 10⁶ ~ 10⁹ Ω/sq, ndipo magwiridwe antchito okhazikika a anti-static ayenera kusamalidwa pambuyo pakutentha kwambiri.

6. Plasma & Chemical Resistance

· Kukaniza kwa plasma: Pochita sputtering ndi PECVD, tepi yovumbulutsidwa ku plasma atmosphere idzakhazikika, kutulutsa ma free radicals a fluorine omwe amaipitsa mafilimu osungidwa ndi kuwononga zipinda za vacuum. Yang'anirani pasadakhale, kapena sinthani ku tepi ya polyimide yosamva madzi a m'magazi ngati kuli kofunikira.

· Kukana kwa Chemical: Nthunzi yotsalira yamafuta ndi zosungunulira zosungunulira zitha kukhalapo pakutentha kwa vacuum; zonse zomatira ndi gawo lapansi ziyenera kukana kutupa ndi zochita za mankhwala.

7. Dimensional Stability & Thermal Shrinkage Rate

Kutsika kwamafuta ochulukirapo pa kutentha kwakukulu kumawonetsa m'mbali zobisika kapena kupanga makwinya omatira, kusokoneza kubisala bwino komanso kufanana.

Zofunikira pazizindikiro : Unikaninso kuchuluka kwa kutentha komwe kumaperekedwa ndi opanga (kuyesedwa pakatha mphindi 30 pa 260 ° C). Tepi ya premium vacuum-grade imachepetsa kuchepa kwa 2% kapena kutsika.

Chidule cha Zosankha Zosankha

Pogula tepi ya PTFE yotentha kwambiri ya malo opanda mpweya, kukana kutentha kokha sikukwanira. Funsani malipoti a ASTM E595 otulutsa mpweya kuchokera kwa ogulitsa, fotokozani momveka bwino momwe ntchito zingakhalire komanso funani matepi apadera otsika mpweya okhala ndi zomatira za silicone zoyeretsedwa. Pazinthu zofunikira kwambiri, yesetsani kuyesa makuponi ang'onoang'ono kuti muyese kusinthasintha kwapang'onopang'ono pa ma vacuum gauges ndikuwunika zomwe zingathe kuipitsidwa ndi zinthu zomwe zatsirizidwa.

Zomwe zili pamwambapa zaukadaulo zimaperekedwa ndi Malingaliro a kampani Jiangsu Aokai New Materials Technology Co., Ltd.

Ngati mukufuna kudziwa mwatsatanetsatane, zochitika ntchito ndi mayankho makonda athu zonse katundu katundu kuphatikizapo PTFE mkulu kutentha nsalu, PTFE mkulu-kutentha zomatira tepi, PTFE mkulu-kutentha mauna lamba, msokonezo kutentha atolankhani lamba, single-mbali PTFE nsalu, mkulu kutentha zosagwira magalasi, kukhudzana ndi magalasi zosagwira magalasi, chonde kukhudzana ndi magalasi zosagwira magalasi conveyor.
