Dhanka aagagga warshadaha, oo ah shey isku daraya guryo badan oo aad u wanaagsan ayaa si deggan u beddelaya qaabka wax soo saarka sare - xaashida ka hortagga tamarta ka hortagga ptfe. Qalabkan shaqeynaya, oo ku saleysan polytetrafluethylen (PTFE) oo lagu daro buufiyeyaasha miisaanka ee Nano, waxay door muhiim ah ka ciyaarataa meelo badan oo muhiim ah oo leh faa'iidooyinkooda gaarka ah.
Qiimaha caabbinta dusha sare ee xaashida ka hortagga ka hortaga cudurka 'ptfe' ayaa si sax ah loo xakameyn karaa 10⁶-10⁸ω. Muuqaalkan muhiimka ah wuxuu u oggolaanayaa inuu sii hayo caabbinta asalka ah ee heerkulka sare iyo heerkulka hooseeya (-200 ℃ ~ 260 lub ℃ ~), is-caabbicyo isku-dhafan, oo si guul leh u xallin lahaa dhibaatada ku saabsan korantada ee PTFE waa u nugul inay aruuriyaan korantada saboolka ah sababtuna tahay in lagu aruuriyo korantada taagan awgeed.
Sababtaas awgeed, waxay aad ugu faa iidaysatay soosaarka semiconductor. Sida shirkad Semiconductor-ka ah, waxay si wax ku ool ah uga hortegi kartaa korantada taagan inay waxyeelo u tahay waxyaabaha saxda ah ee elektiroonigga ah. Qalabka kiimikada ah, waxay u dhaqmeysaa sidii dib-u-habeyn ah oo laga hortago warbaahinta ololi kara iyo waxyaabaha qarxa laga soo bilaabo sababa shilalka amniga awgood. Gudaha garoonka Aerospace, waxay sidoo kale ku taal meel ay ku jiraan waxqabadka deggan.
Si kastaba ha noqotee, qalabkan waxqabadka sare wuxuu wajahayaa caqabado badan inta lagu gudajiro howsha, laakiin warshadaha ayaa helay xalal hal-abuurnimo ah qaab bartilmaameed ah.
Inta lagu gudajiro howsha, mushkiladii ugu horreysay ee ay la kulmeen go'yaasha anti-stat-stat-ptfe waa cod-ka-qaad aad u sarreeya oo adag Heerkulka dhalaalaya ee PTFE waa mid sare oo ah 327 ℃, iyo viscosity-ka iyo dheecaanka ee gobolka la shiilay aad iyo aad u adag, oo ay adag tahay in la sameeyo tikniyoolajiyadda hawsha ee caadiga ah. In kasta oo hawsha saxaafadda qabow iyo ciqaabtu ay tahay habka ugu weyn, waxay leedahay shuruudo adag, oo ay ku leedahay cadaadis (300kg / cm²) iyo heerkulka dembiga (370 ℃), iyo haddii aadan u horseedi doonin in la jeexjeexo badeecada ama dillaacyada dusha sare.
Si wax looga qabto dhibaatadan, warshadu waxay qaadatay xalka kor u kaca hab-dhaqanka ee hab-dhaqanka. Tikniyoolajiyadda-tallaabo-tallaabo ee-kombuyuutarka waxay yareyn kartaa polsit-ka gudaha ah in ka yar 0.5% iyada oo loo marayo qalooca cadaadiska ee isdaba-joog ah (pre-riixista 17-35mpa → Cadaadiska ugu weyn 50-80mppa) iyo waxyaabo badan oo "degassing". Nidaamka xakameynta heerkulka ee heerkulka ah wuxuu soo bandhigayaa cabirka heerkulka heerkulka iyo pid algorithm si loo xakameeyo heerkulka ee heerkulka ku dhaca ± 2 ℃, hubinta in walxaha PTFE ay si buuxda u duuban oo aan la soo gaarin.
Kala furfurnaan aan sinnayn ee buuxiyeyaasha wadnaha ayaa ah arin muhiim u ah saamaynta waxqabadka ka hortagga antistasica. Haddii hannaanka firfircoonaanta uu yahay mid aan habooneyn, waxay u horseedi doontaa shabakadda qabsashada ee maxalliga ah in la joojiyo, taasoo keenta isbeddelada isuduwaha dusha sare. Tusaale ahaan, nanotubabes kaarboon-ka-qaadeyaasha ah ayaa sameeya agglomerates ee ku jira PtFE Matrix, oo ka dhigi doonta waxqabadka daadadka ee maxalliga ah ee maaddada aan waxtar lahayn.
Iyada oo laga jawaabayo tan, tikniyoolajiyadda kala-guurka ee buufinta ah ayaa lagu soo bandhigay hal-abuurnimo. Hydroxylation of kaarboon nanotubes (tus. Xalka isku dhafka ah ee hno₃ / h₂so₄ Isku-darka ultrasonic vibrator (soo noqnoqoshada 20khz 20khz, awoodda 500w) ee mataanaha lagu turunturoodo wuxuu yareyn karaa cabirka walxaha ku kala firidhsan ee PTFETERTETERS oo ay kor u qaadaan sii wadida shabakadda jimicsiga ee 60%.
PTFE waxay leedahay tamar dushooda oo aad u hooseeya Waxyaabaha qalabka korantada ee dabaysha ee loo baahan yahay in lagu daro xirmooyinka birta, xoogga hurta ee anoesives-ka dib-u-dhigga ee caadiga ah ayaa ka yar 0.1N / MM, oo aan buuxin karin baahiyaha isticmaalka muddada-dheer.
Si loo xaliyo dhibaatada this ee isku-darka, dhaqdhaqaaqa dusha sare iyo isku-darka xoojinta istiraatiijiyadda xoojinta ayaa soo ifbaxay. Dusha sare ee PTFE waxaa lagu ridayaa Argon Plasma (Awoodda 100W, waqtiga loo maro 3 daqiiqo), si ay dusha sare u kaxeyso 1.2μm ilaa 1.2 milyan oo kale, iyo xayiraadda loo yaqaan 'hyroxyl' iyo carbonyl-ka ayaa la kordhiyay si loo kordhiyo xoogga xamuulka ee 9mpa; 50 milyan oo qaro weyn oo la beddelay
Intaas waxaa sii dheer, halista dheecaan elektriostatic ah ee jawiga laga baaraandego lama illoobi karo. Inta lagu gudajiro howsha, kala-goysyada u dhexeeya aaladda iyo sheyga, xabagta xaydha, iwm ayaa sii kordhin doonta korantada taagan. Jawiga qallalan (huurka <30%), korantada korantada ee dusha sare ee xaashida PTFE waxay noqon kartaa ugu badnaan dhowr kun oo Volt, oo aan sidoo kale saameyn ku yeelan karo saxsanaanta korantada, laakiin waxay sababi kartaa nabarro koronto iyo nabadgelyo gelin khatar ah.
Arintan, qorshaha xakamaynta ee hawsha ee ku saabsan dheecaanka korantada ayaa ka ciyaara door. Ku rakib huuriy / huuriyuhu ku rakibo aqoon-isweydaarsiga ka shaqeynta si loo dejiyo huurka 50% ± 5%, yareynta dusha sare ee iska caabbinta maaddada ilaa ka hooseeya 10⁹ω, iyo yareynta korantada taagan; Isku-darka aaladda safka naxaas ah (iska caabbinta <1ω) qaybaha muhiimka ah sida goynta aaladaha iyo wasaqda ee xawaaraha ion (5m / station) si loo xakameeyo korantada korantada ee heerka korantada 100v.
Codsiga xalkan ayaa ka dhigaya waxqabadka go'yaasha anti-set-ka ee PTFE xitaa si ka sii wanaagsan qaybaha kala duwan. In Semiconductor-ka qolka nadaafadda, caabbinta dusha sare ee xaashida ka hortagga ptfe ee ka hortagga plasma dusha sare waa mid xasilloon yahay 102% xaashiyaha ciidda aan la daaweyn, la kulma shuruudaha nadaafadda ee fasalada ISO; Xaashida kombiyuutarka ee 'totrauterka' totrout-ka '' puter putrode puted ', caabbinta mugga ee xaashida ayaa loo yareeyay 10¹³ω · teknoolojiyadda koobiyeynta isku-darka ee Karbonuberiga ee ay keento korantada taagan, iyo heerka korantada ayaa ka kordha 85% ilaa 98%; Nidaamka Dawladda Daweynta ee Xoogga, Xaashida PTFE ee lagu daaweeyay qaab-dhismeedka is-qoritaanka ee guud ee ah jawiga ku buufiska milixda (5000 saacadood), oo ah 3-da saacadood ka sareeya nidaamka dhaqanka, oo dib loo warshadeeyo 100% dib loo isticmaali karo.
Iyada oo loo baahan yahay baahida loo qabo agabka anti-static ee 5G isgaarsiinta, tamar cusub iyo beero kale, go'yaal ka hortaga ptfe-ka ah ee PTFE-da ayaa u dhaqaaqaya is dhexgalka wada-xiriirka. Iyada oo loo marayo isku-darka xargaha xargaha xargaha nano iyo kaarboon-ka-dhigga, caabbinta dusha sare ee ka hortagga (caabbinta dusha sare> 40d), heerka is-dayactirka microcrack> 90%) ayaa la gaari karaa isku mar. Intaas waxaa sii dheer, isku-darka tikniyoolajiyadda 3D oo riixitaan ah oo lagu dhajinayo wareejinta caado ee qaybo ka mid ah qaybaha qaab-dhismeedka qaaska ah ee ka badan 50%, iyagoo siiya meel cusub oo horumarineed oo wax soo saar ah oo sareeya.
Shirkaddeenu waxay si qoto dheer ugu mashquulsan tahay balaastigga injineerinka waxqabadka sare, waxaana ka go'an inay siiso xalka maaddada hal-abuurka ah ee warshadaha soo-saarka ee ugu sareeya. Alaabooyinkayaga ugu muhiimsan waxaa ka mid ah go'yaal caag ah oo dhameystiran sida poloyoxymymerene (pom), polycharbonate (polychertonenenene (polyphertones), iwm), polyphertones (polythertone), phenole-ka (phenethertone) iyo gudiga galaaska galaaska ephox. Iyada oo leh guryo aad u wanaagsan sida caabbinta heerkulka sare, iska caabbinta, iyo xoog sare, alaabooyinkeena ayaa si weyn loogu adeegsadaa gawaarida tamarta cusub, mashiinka elektaroonigga ah, mashiinnada warshadaha, aerospace iyo beero kale.
