Ese ikirere-kirwanya ikirere PVDF Gipfundikirwa amabati ya aluminiyumu Kwirinda ubushyuhe bwimbere mu nzu ya robo yo hanze?

Mu igenzura ry’ibikorwa remezo byigenga, ubuhinzi bwubwenge, kurinda perimeteri, n’umutekano w’icyambu, ibigo bya robo byo hanze - cyane cyane ibyigenga byigenga 'drone-in-a box ' (DiaB) hangar, robot igendanwa yishyuza kiosque, hamwe n’akabati y’itumanaho rya mudasobwa - ikora ku mucyo w'izuba. Bishyizwe mumashanyarazi afunguye, imirima yubuhinzi, perimetero yubutaka, hamwe nubutayu, ibyo bigo byo hanze bigomba kurinda imitwaro ya elegitoroniki yumuriro munsi yumurasire wizuba urenga 1.000 W / m² n'ubushyuhe bwo mu kirere burenze 40 ° C.

Imbere yimbere yimodoka itagira drone yubatswe ifite ubutumwa bukomeye, butita ku bushyuhe: bateri ya lithium-ion ibyuma byihuta byihuta, ibyuma byinshi byo guhinduranya imashini za robo, ibyuma bibiri bya RTK-GNSS byimyanya ndangagitsina, byashyizwemo seriveri ya GPU, hamwe nintego zo guhitamo neza. Iyo ingufu zikomoka ku mirasire y'izuba zinjiye mu kigo byihuse kuruta uko zishobora gukwirakwira, ubushyuhe bw'imbere bwazamutse hejuru ya 65 ° C kugeza kuri 75 ° C, bigatuma ibyuma bikomeye byananirana:

Thermal Throttling & Battery Degradation: Ubushyuhe bwo hejuru bwimbere butuma bateri yindege ya drone yinjira mumashanyarazi, bikarinda kwishyurwa byihuse kandi byihutisha imbere imbere-ikomeye ya electrolyte interfease (SEI) kumeneka, kugabanya ubuzima bwa cycle ya batiri kurenza kimwe cya kabiri.

Ibihano Bikomeye bya HVAC & Kwiyegereza: Uruzitiro rufite ibyuma bikonjesha bya termoelektrike cyangwa ibyuma bifata ibyuma bikonjesha bikoresha ingufu za batiri cyangwa ingufu za gride kugirango zirwanye ubushyuhe bukabije. Gukonjesha byihuta cyane akenshi bitera kwangirika kwimbere, bigatuma amazi atemba yimiterere yabantu kumashanyarazi yumuriro mwinshi hamwe na lens optique.

Imyubakire yubushyuhe yubushyuhe & Gasket: Ibicuruzwa bituruka ku zuba bitaringaniye bitera ibisenge binini hamwe ninzugi zicamo ibice byunamye kandi bigoreka. Uku kugoreka kurekura ikirere cyangiza ikirere, bigatuma imvura itwarwa n umuyaga, umusenyi wo mu butayu, hamwe nubushuhe bw’ibidukikije kugira ngo ucyure IP66 / IP67 ifunze umuyaga wa elegitoroniki.

Mugihe amazu asanzwe asize irangi hamwe na fiberglass amazu yumutego wumuriro wizuba, irwanya ikirere PVDF yometseho urupapuro rwa aluminiyumu (cyane cyane muri 5052-H32 cyangwa 5754-H22 ivangwa ryakozwe na pigment ya pigiseli yerekana hafi) itanga igisubizo gifatika. Muguhuza ubushyuhe bwo hejuru bwumuriro wa aluminiyumu hamwe n’uruganda rushyizwe mu bikorwa, 70% ya fluoropolymer yakozwe mu cyerekezo gikabije cy’izuba ryinshi (SRI ≥ 82), ibi bikoresho byerekana ubushyuhe bwumuriro bwinjira, bikwirakwiza vuba ahantu hashyushye hashyushye, bigabanya ingufu zikoreshwa n’umuyaga mu kirere hejuru ya 60% ugereranije n’ibyuma.

Imiterere umvange wa aluminiyumu s ya Byinshi-Bikora Hanze Hanze ya Robo

Indege ya drone yigenga hamwe nububiko bwa robotics yo mu murima bisaba guteranya imiterere ihuza ubukana bukabije, gukwirakwiza ubushyuhe bwinshi, hamwe na misa ntoya:

Umusaruro mwinshi 5052-H32 na 5754-H22 Substrates Structures: Yakozwe na 2,2% kugeza kuri 3,6% ya magnesium, aya mavuta ya aluminium-magnesium akora cyane atanga umusaruro wemewe hagati ya MPa 160 na MPa 215. Ibi bituma amababi manini manini ya hangar hamwe nibibaho (bigera kuri mm 1.500 × 3000 mm) birwanya amavuta hamwe no guhindagurika mugihe cya kilometero 140 / umuyaga uhuha.

Gucisha bugufi Tare Uburemere & Transport Inertia: Hamwe n'ubucucike bwa 2,68 g / cm³ ugereranije nicyuma cya 7,85 g / cm³, uruzitiro rwa aluminiyumu rugabanya ibice byubatswe hafi 65%. Ibi bituma ibyuma byindege zitagira abadereva bizamurwa na crane ya serivise yoroheje cyangwa igashyirwa ku minara itumanaho ihanitse no kubaka ibisenge hejuru idafite imbaraga zubaka.

Kurangiza Ubushyuhe Bwinshi & Kurandura Bishyushye: Aluminiyumu itanga igipimo cyogukoresha ubushyuhe buri hagati ya 138 W / m · K na 150 W / m · K - inshuro zirenga eshatu hejuru yicyuma cya karubone ninshuro amagana kurenza plastiki yibumbiye hamwe. Iyo imirasire y'izuba ikubise hejuru yinzu, intangiriro ya aluminiyumu ikoresha ingufu zubushyuhe bwihuse kuruhande rw ibahasha yose, igahindura ubushyuhe bwumuriro bwaho mukarere gakwirakwira.

Hafi-Infrared Yerekana PVDF Ubwubatsi & Ubuso Nanotehnologiya

Irangi risanzwe ryinganda rikurura ubushyuhe butagaragara bwizuba, mugihe ibyuma byambaye ubusa bihindura kandi bikangirika mumyuka yo hanze. Uruganda rukomeza rukoreshwa- PVDF ats ibishishwa bifashisha ubukonje-chimie nanotehnologiya:

70% Fluoride ya Polyvinylidene (Kynar 500 / Hylar 5000) Resin Matrix: Ipitingi ikoreshwa mu ruganda ikoresha umugongo ufite uburemere buke bwa fluoropolymer umugozi uhujwe n’ingufu nyinshi za karuboni-fluorine (CF) ihuza imiti (> 485 kJ / mol). Iyi matrike ya molekile ihanganira imyaka mirongo imirasire yizuba ikabije idafite imirasire idahwitse, micro-crazing, ibara ryangirika, cyangwa ubushyuhe bwumuriro.

Ibara ryibara ryimbaraga (CICP) kugirango NIR Yerekane: Aho kwishingikiriza kumyuka gakondo ya karubone yumukara cyangwa ibinyabuzima bikurura ubushyuhe, ikoti yo hejuru irimo ibyuma-bivanze-oxyde ikonje. Izi pigment ziragaragara neza muburyo bugaragara (bujyanye n'amabara agenga ibigo) mugihe ikora nkindorerwamo zigaragaza cyane murwego rwo hafi ya infragre (NIR) (700 nm kugeza 2500 nm), itwara hejuru ya 50% yingufu zizuba.

Ubushyuhe bwo hejuru bwa Thermal Emissivity & Kwiyuhagira Fluoropolymer Kurangiza: Ubuso bwakize PVDF butanga ibyuka byoherezwa hejuru (≥ ε 0,85), bikwirakwiza ingufu zumuriro zisubira mu kirere mugihe cyizuba. Byongeye kandi, imbaraga zayo zidasanzwe cyane (<22 mN / m) isuka umukungugu wo mu kirere hamwe na grime mugihe cyumuyaga wimvura, bikarinda ibisigazwa byanduye byangiza izuba.

Ibibazo

Q1: Ese kuringaniza PVDF birashobora rwose gukumira izuba ryinshi ridafite ubukonje bukora?

Igisubizo: Mugihe igifuniko kidashobora kugabanya ubushyuhe bwimbere munsi yubushyuhe bwikirere bwo hanze hatabayeho gukonjesha gukabije, ibyerekanwa hafi ya infragre inf PVDF gutwikira birinda imirasire yizuba gutwara ubushyuhe bwimbere hejuru yurwego rwibidukikije. Mugaragaza kugeza 85% byubushyuhe bwizuba no gukwirakwiza vuba ahasigaye, uruzitiro ruguma muri 2 ° C kugeza kuri 5 ° C yumuyaga w’ibidukikije hanze, bikuraho imirasire yizuba ya 20 ° C kugeza 30 ° C isanzwe yisanduku yicyuma gisanzwe.

Q2: Ni irihe tandukaniro riri hagati y irangi ryera risanzwe hamwe na pigment ikonje PVDF gutwikira?

Igisubizo: Irangi ryera risanzwe ryerekana urumuri gusa muburyo bugaragara (400 nm kugeza 700 nm) kandi akenshi bikurura ubushyuhe bugaragara hafi ya infragre (700 nm kugeza 2500 nm), mugihe kumeneka no gukandagira munsi yimirasire ya UV hanze mumyaka mike. Cool-pigmented PVDF

Q3: Ese ibara rya PVDF ating gutwikira ikintu cyo gukora ubushyuhe?

Igisubizo: Yego, ariko tekinoroji ya pigment ituma amabara yijimye abaho. Mugihe ibara ryera kandi ryerurutse ryijimye- PVDF ats ibishishwa bigera ku cyerekezo cyo hejuru cy’izuba ryinshi (SRI 85 kugeza 95), icyatsi kibisi, icyatsi kibisi, cyangwa ubururu bukonje-pigmented PVDF imyenda iracyagera ku gipimo cya SRI kiri hagati ya 60 na 75 (ugereranije na SRI 15 kugeza 25 ku marangi asanzwe yijimye). Ibi bituma abubaka ibikoresho byuzuza ibirango byamasosiyete cyangwa ibisabwa bya kamera badateze ubushyuhe bukabije.

Q4: Nigute amashanyarazi ya aluminiyumu afasha gukumira ahantu hashyushye muri hangari?

Igisubizo: Aluminium ikora ubushyuhe bugera kuri 138 W / m · K, ugereranije na 45 W / m · K ku byuma bya karubone na 0.2 W / m · K kuri fiberglass. Iyo hejuru yuruzitiro rwicaye munsi yizuba ritaziguye mugihe impande zicucu, imiyoboro ya aluminiyumu itwara ubushyuhe iva hejuru yinzu ishyushye ikagera kurukuta rwuruhande rukonje, ikwirakwiza kandi igasuka imitwaro yubushyuhe hejuru yubuso bwose.

Q5: Ese imbaraga za fibre zifite imbaraga nyinshi zo kugabanya ibyangiritse cyangwa gutwika igisenge gikonje PVDF kizarangira?

Igisubizo: Oya, hatanzwe ingufu za azote ifasha gaze (12 kugeza 18 bar) irakoreshwa. Indege ya azote yihuta cyane yimura icyuma gishongeshejwe ako kanya kerf, bigatuma zone yibasiwe nubushyuhe (HAZ) munsi ya mm 0.1. Uruganda rukize rwa termoset PVDF ating gutwika gukata neza hamwe na zeru zijimye, guhuha, cyangwa guhindura ibara.
