Maqaalkani waxa uu eegayaa saamaynta nooca platina ee kicinta iyo u fiirsashada isku xidhka kinetics-ka caag silikoon ah oo dheeraad ah. Noocyada kicinta: Xakamaynta Speier (chlorolatinic acid, Pt⁴⁺) waxay u baahan tahay hoos u dhigista noocyada firfircoon ee firfircoon ee hooseeya, oo u shaqeynaya sidii hore; Karstedt catalyst (Pt⁰ leh divinyltetramethyldisiloxane) waxay si toos ah u gashaa wareegga catalytic. Saamaynta Nooca: Speier wuxuu muujiyaa muddada soo-bandhigista ee dhawaaqa leh qalooca bogsashada S-qaabeeya (ayar tartiib ah, la dedejiyey dambe) iyo tamar firfircoon oo muuqata; Karstedt ma muujinayso soo-galin, heer hore oo sarreeya oo leh exotherm fiiqan, tamar firfircooni hoose.

Maqaalkani waxa uu daboolayaa fursadaha codsiga ee Teflon dharka heerkulka sare ee warshadaha batteriga adag ee soo baxaya. Afar meelood: Soo saarista korantada qalalan/xuubka korantada - Heerkulka heer-sare ee ka-hortagga-ulaha suunka ee cadaadiska duubka kulul (150-250°C) awood u siinaya in si siman loo diiriyo filimada is taageera; lakabka daboolka rullaluistemadka kulul sida lakabka ka hortagga-ulaha nus-joogta ah; waxay hubisaa dusha filimka siman, waxay yaraynaysaa cilladaha, waxay hagaajisaa dhalidda. Xadhkaha la sii daayo iyo suufka barkinta ee cufan-cadaynta kulul - baytariyada sulfide/polymer waxay u baahan yihiin cadaadis istaatig ah oo kulul (100-300 ° C, tobanaan MPa); Dharka PTFE ee la dhigo inta u dhaxaysa batteriga iyo caaryada waxay ka hortagtaa adhesion, waxay awood u siineysaa qaybinta cadaadiska isku midka ah iyada oo loo marayo dabacsanaan yar, waxay ilaalisaa taarikada kuleylka.

Maqaalkani waxa uu daboolayaa waraaqaha tirada ee u dhexeeya jajabka jel iyo xoogga isku xidhan ee xabagta cadaadiska-silicone ee cajaladda Teflon. Jajabka jel = boqolkiiba tirada guud ee shabakada isku xidhan ee aan lagu milmi karin toluene (Soxhlet soo saarista, 24hr). Awood isku xiran oo lagu garto heerkulka sare ee awoodda (180 ° C, 1kg). Saddex qaybood: ka hooseeya barta muhiimka ah (<60%) - ma jiro shabakad isku xidhan, awoodda ku haysa eber; kala duwanaansho wax ku ool ah (60-85%) - xoogga isku xiran ayaa si aad ah u koraya iyadoo leh jajab jel, 60% → 70% waxay kordhisaa waqtiga haynta daqiiqadaha ilaa saacadood, 70% → 80% waxay siisaa 3-10x koror; isgoysyada sare (> 85%) - guulo gaabis ah (85% → 95% kaliya 20-50% koror), garaaca si weyn hoos ugu dhaca,> 95% luminaya guryaha PSA.

Maqaalkani wuxuu eegayaa isbeddelada silsiladaha molecular ee PTFE ee hoos yimaada shucaaca ultraviolet. Maqaarka silsiladda ugu weyn iyo dhimista miisaanka kelli: UV (254nm, 471 kJ/mol) waxay jebiyaan curaarta CC (347 kJ/mol), taasoo keenaysa homolysis, abuuritaanka CF₂-la joojiyay xagjirrada xorta ah, hoos u dhaca miisaanka unugyada fiiqan, luminta adkaanta iyo dhererka. Dariiqooyinka falcelinta xagjirka ah ee bilaashka ah: gudaha oksijiinta, radicals peroxy, dib u habeynta acyl fluoride (—COF) iyo karboksylic acid (—COOH) kooxaha dhamaadka, siidaaya COF₂ iyo CO₂ (COF₂ hydrolyzes ilaa HF); jawiga aan firfircoonayn, isu-dheellitirnaanta/dib-u-isku-dhafka ayaa ka sarreeya, laakiin maqaarka silsiladda ayaa weli ah mid aad u sarreeya.

Maqaalkani waxa uu daboolayaa codsiga Teflon dharka heerkulka sare ee lakabyada kuleylka kuleylka. Nuxurka walxaha: PTFE-dahaarka dharka fiberglass, oo hawada sare loo yaqaan sida dharka Beta, isku darka dabacsanaanta dharka iyo PTFE degenaansho la'aanta deegaanka ee xad dhaafka ah. Doorka: lakabka ugu dambeeya ee dharka Thermal Micrometeoroid (TMG) ee cutubyada dhaqdhaqaaqa ka baxsan, si toos ah u wajahan faakuum, kala duwanaanshiyaha heerkulka xad dhaafka ah, iyo micrometeoroids oo ah xannibaadda ugu horeysa ee jireed / kulaylka ee filimada aluminium gudaha ah. Ilaalinta deegaanka ee aadka u daran: waxay u adkaysataa -200°C ilaa +260°C kala duwanaanshaha (qorrax-ujeedka>120°C ilaa hadh -160°C); dusha cad waxay ka tarjumaysaa shucaaca qorraxda; waxay ka ilaalisaa aluminium aluminium filimaanta jilicsan xagashada iyo ilmada. Caawinta dhaqdhaqaaqa: xoqida hoose ee dusha sare ee PTFE waxay ka hortagtaa isku dhufashada lakabka inta lagu jiro foorarsiga wadajirka ah, hubinta dabacsanaanta EVA.

Maqaalkani waxa uu daboolayaa faa'iidooyinka codsiga Teflon dharka heerkulka sare ee lithium batteriga qalajinta. Loo isticmaalo sidii suumanka gudbinta ama foornada, xalinta saddex mashaakil oo asaasi ah: xabagta slurry, daxalka, iyo xoqitaanka korantada. Afar meelood oo faa'iido leh: Tayada korantada iyo wax-soosaarka - guryaha lidka ku ah waxay ka hortagayaan ku-xidhka PVDF ee awood u siinaya diirritaan dhammaystiran oo fudud; kulaylka isku midka ah ee 100-140 ° C waxay ka hortagtaa dildilaaca / gubashada; dusha siman waxay baabi'isaa xagashada iyo daadinta budada; Waarta iyo xasilloonida hawlgalka - iska caabbinta kiimikaad ee ka soo horjeeda dareeraha NMP iyo uumiga korantada iyada oo aan barar / gaboow lahayn; xoogga sare ee xajinta iyo xasilloonida cabbirka ee ka soo baxa substrate-ka fiberglas-ka ee meelaynta saxda ah; nadiifin fudud oo leh hadhaaga ugu yar marka loo eego suumanka mesh birta.

Maqaalkani waxa uu daboolayaa sida loola jaanqaadi karo heerkulka burburka iyo nolosha nuska ah ee wakiilada isku xidhka ee peroxide (BPO iyo DCP) oo leh daaqada habka daaweynta ee cajaladda Teflon. Xogta muhiimka ah: BPO - 1-daqiiqo nus-nolosha ~ 131 ° C, 1-saac at ~ 92 ° C, 10-hr at ~ 72 ° C; DCP — 1-daqiiqo at ~171°C, 1-saac at ~135°C, 10-saac at ~115°C. Macquul iswaafajinta: baahida xabagta 97-99% isdhaafsi = 5-7 nolol badhkeed; waqtiga daawaynta = 5-7 × nolosha badhkeed heerkulka bartilmaameedka ah. Dib-u xisaabi heerkulka laga soo bilaabo wakhtiga xariiqda wax soo saarka ama dib-u xisaabi wakhtiga heerkulka ugu sarreeya ee la oggol yahay.

Maqaalkani waxa uu daboolayaa kala duwanaanshaha xawaaraha khadka caadiga ah ee PTFE xarriiqda wax-soo-saarka heerkul-sare ee dharka. Xawaaraha caadiga ah: 2-15 m/min, kala duwanaansho hawleed deggan 3-8 m/min, dhar khafiif ah/xawaaraha sare ilaa 10-15 m/min. Caqabadaha ka imaanaya gelitaanka impregnation: dharka waa in si buuxda loogu buuxiyaa emulsion PTFE gudaha xirmada fiber-ka-xawaaraha aad u sarreeya wuxuu keenaa impregnation ku filan, gaajo resin iyo fiilooyinka qallalan; viscosity emulsion, fiirsashada adkaha, cufnaanta tolmada dharka dhamaantood waxay yareeyaan heerka dhexgalka, oo u baahan xawaare gaabis ah oo loogu talagalay dhar qaro weyn / cufan. Dahaarka baasas: baas badan (2-6+) looga baahan yahay daahan cufan oo aan cilad lahayn; marka hore si tartiib tartiib ah u dhaafitaannada, baasaska xiga ayaa si dhexdhexaad ah loo kordhin karaa.

Maqaalkani waxa uu isbarbar dhigayaa kala duwanaanshaha udhaxeeya kulaylinta shucaaca infrared iyo kulaylka wareegga hawada kulul ee isku midka ah qaabdhismeedka isku xidhan ee lakabka xabagta silikoon. Hababka wareejinta kulaylka: hawada-kululku waa hawo-qaadis, dabacsanaan iyo horumar, abuurista heerkul dhexdhexaad ah; IR waa shucaac-nuugista oo leh nuugista dusha sare (micrometers ilaa millimeters) taas oo abuuraysa jaan-gooyo sare-ilaa-gudhood. Saamaynta cufnaanta isku-goysyada: hawada kulul waxay u oggolaanaysaa qaybaha gudaha iyo dibedda inay galaan heerkulka vulcanization isku mar, taasoo keenaysa cufnaanta isku-goysyada isku midka ah ee dhumucda leh; IR waxay keentaa lakabka korka inuu bogsado isla markaaba samaysma maqaarka cufan kaas oo hor istaaga kala wareejinta kulaylka, taasoo keentay in cufnaanta isgoysyada ay hoos u dhacdo korka gudaha.

Maqaalkani waxa uu daboolayaa nuxurka silica iyo xaaladaha codsiga ee muraayadda fiber-ka-sare ee silica. Qeexida nuxurka silica: tilmaame xudunta u ah waa SiO₂ ≥96% (heerka 96-98%, darajooyinka qaaliga ah>99% iyada oo la adeegsanayo dheecaanka aashitada iyo sintering, soo dhawaada fiber quartz saafi ah). Wax-soo-saarka: Dharka E-glass-ku wuxuu maraa dheecaanka aashitada kulul si ay u milmaan qaybaha aan silica ahayn (boron oxide, sodium oxide), abuurista qalfoofka silica-sare ee dalool leh, ka dibna loo miiray cufnaanta. Faa'iidooyinka asaasiga ah: adeegga joogtada ah ee 900 ° C ee jawiga oksaydhka, muddada gaaban ee ka sarreeya 1200 ° C, barta jilicsan ee u dhow 1700 ° C; xasilloonida kiimikaad ee ka dhanka ah inta badan asiidhyada/alkaliska marka laga reebo HF iyo fosfooraska kulul; dielectric hoose oo joogto ah iyo dahaarka deggan heerkulka sare.
