Nigute Low- imiterere y’umvange ature Flexible Coated Aluminium ikora muburyo bwo kohereza ibicuruzwa bya Arctique?                

Inzira y'ibikoresho bya polarike, inzira zo kohereza Arctique, hamwe na transport ya firigo ya sub-zeru ihura nubushyuhe bukabije bwumuriro, guhindagurika kwizuba ryikurikiranya, hamwe ningaruka zumubiri zikabije kubushyuhe bugabanuka kugera kuri 50 ° C  cyangwa munsi. Kwambika ibyuma bisanzwe hamwe no gutwikisha ibintu bigoye gucika intege cyane mubihe bya arctique, bikaviramo micro-gucika hejuru, gutakaza irangi ryamabara, gusibanganya imiterere, hamwe no kunanirwa kwamashyanyarazi mubiterane byurukuta rwa kontineri.

Muguhuza aluminiyumu yihanganira ubukonje ( 3000/5000 seri ) hamwe na byateguwe cyane na fluoropolymer ya elastomeric cyangwa sisitemu yo gutwikira ibirahuri bito ( T ), ubushyuhe buke bworoshye bwa aluminiyumu itanga ingaruka zidasanzwe, kugabanya ikiraro cyumuriro, hamwe nigihe kirekire. Ikomeza kwifata neza kugeza kuri -60 ° C , ikarinda kwinjiza ubuhehere no kubungabunga ubushuhe bwubushyuhe bwubushyuhe bwububiko bwa Arctic yohereza ibicuruzwa.

Ubukanishi bwububiko bwa Alloy Substrate

Kohereza kontineri yambitswe ikoreshwa mubidukikije bisaba imbaraga zitanga umusaruro mwinshi hamwe nubushyuhe buke:

5052-H34 / 3004-H24 Substrate: Bitandukanye nicyuma cya karubone cyerekana ubushyuhe bwinzibacyuho iteye ubwoba (DBTT), aluminium igumana ubukana bwinshi, kuramba, no gutanga imbaraga mugihe ubushyuhe bwagabanutse munsi ya zeru.

Ibikorwa byoroheje byubaka: Kugabanya uburemere bwa kontineri (2,71 g / cm³) mugihe ushyigikiye imitwaro iremereye mugihe cyo gutwara inyanja iremereye no gutambuka gukabije.

Ikirahure gito-Inzibacyuho ( T ) Ikoreshwa rya Polymer

Igipimo gisanzwe cya termosetting gihinduka munsi ya 0 ° C kubera ko ubushyuhe bwibidukikije bugabanuka munsi yubushyuhe bwikirahure ( T ). Ubushyuhe buke bwo guhindagurika burwanya ibi binyuze muri chimie yahinduwe:

Ultra-Low Glass Transition imiterere y’umvange ature (T ≤-60 ° C): Harimo ibice byoroshye bya alifatique polyolefin cyangwa elastomeric FEVE / PVDF ibice biguma muburyo bworoshye, bwa rubberi mugihe cy'ubukonje bukabije.

Umuyoboro mwinshi wa Polymer: Ukomeza kuramba kurenze 150% kubushyuhe bwa sub-zeru, bigatuma igipfundikizo gihindagurika, cyaguka, kandi kigasezerana kijyanye na substrate ya aluminiyumu idacitse.

Kwemeza Tekinike & Ibipimo ngenderwaho

Imikorere ya matrix ikurikira irerekana ibipimo ngenderwaho byingenzi byo gupima laboratoire yubushyuhe buke bworoshye bwa aluminiyumu:

Ibyingenzi Byumwuga Mubyububiko bwa Arctique

Ibibazo

Q1: Kuki impuzu zisanzwe zananirana muri Arctic yohereza ibicuruzwa?

Igisubizo: Ibifuniko bisanzwe bifite ubushyuhe bwo hejuru bwikirahure ( T ). Iyo ihuye nubushyuhe bwa arctique iri munsi ya -20 ° C , bihinduka ibirahure, bigatuma irangi rivunika, rigahinduka, kandi rikabura aho rihurira mugihe urukuta rwa kontineri ruhindagurika cyangwa rukagira ingaruka.

Q2: Nigute ubushyuhe buke bworoshye bwa aluminiyumu irinda ibikoresho bya PU?

Igisubizo: Mugukomeza inzitizi ikomeza, itavunika imyuka, irinda umwuka wubushuhe nubushuhe kwinjira mubice bya insimburangingo ya polyurethane, kurandura ibibarafu no kugumana agaciro gakomeye ko kubika ubushyuhe ( R-agaciro ).

Igisubizo: Yego. Ipfunyika rya elastomeric fluoropolymer ituma 1T - 2T  igoramye kandi yunvikana cyane mubushyuhe bwicyumba cyangwa ahantu hakonje hatabayeho gukata mikoro cyangwa gutakaza inkombe.

Q4: Intangiriro ya aluminiyumu iracika intege mubushyuhe buke cyane nkicyuma cya karubone?

Igisubizo: Oya. Imbaraga zayo zingana, zitanga imbaraga, nubukomezi mubyukuri bigenda byiyongera uko ubushyuhe bugabanuka.

Q5: Ni ubuhe buzima buteganijwe bwa serivisi yo hasi ya temp yoroheje ya aluminiyumu yambitswe inzira yo kohereza polar?

Igisubizo: Iyo bikozwe hamwe na elastomeric yo mu rwego rwo hejuru FEVE / PVDF fluoropolymers na aluminium yo mu nyanja, sisitemu yo kwambara itanga ubuzima bwa serivisi ikora kurenza imyaka 20 kugeza kuri 25 hamwe no kuyitaho bike.

Umwanzuro

Amabati ya aluminiyumu yubushyuhe buke itanga igisubizo cyingenzi kubikoresho byoherejwe na Arctique yohereza ibicuruzwa, kurinda ubushyuhe, kurinda ubushuhe, hamwe nuburinganire bwimiterere mubihe bikomeye bya kirogenike.

Kugirango uhindure ibikoresho byatoranijwe kubikoresho byoherejwe na zeru:

Kugaragaza E-Elastomeric yo system igipfundikizo hasi

Hitamo Kutavunika Aluminium Core (5052-H34 cyangwa 3004-H24): Menya neza ko substrate igumana uburebure burebure hamwe ningaruka zikomeye mubidukikije bya zeru.

Manda ya Cryogenic Cold-Bend kubahiriza: Saba raporo yikizamini cyemeza yemeza ko 1T yunamye kandi igabanuka ryibiro byakozwe kuri -40 ° C cyangwa munsi yayo.
