Gusobanukirwa Amasaha yikizamini cyumunyu: Guhitamo Amabati ya Aluminiyumu yo hejuru yinyanja

Inyubako zubatswe muri zone yinyanja - ubusanzwe zisobanurwa nkibice biri muri metero 1.000 kugeza kuri kilometero 5 zumusenyi winyanja - byerekana ibikoresho byo gusakara kubidukikije bikaze. Ikirere cyo mu nyanja gihuza ubutumburuke bukabije bwo mu kirere, imirasire y'izuba ikabije, hamwe n'umunyu uhoraho wo mu kirere (sodium chloride). Igisenge cy'icyuma kidakingiwe cyangwa kidakwiye neza aha hantu gishobora guhura nubutaka bwihuse, gucika intege, no kunanirwa kurangi.

Kugirango dusuzume imikorere yibikoresho mbere yo kwishyiriraho, abaguzi b'ibyuma n'abubatsi bishingikiriza ku buryo bwihuse bwihuse bwo kwangirika, cyane cyane umunyu spray test ya protocole ya aluminium. Gusobanukirwa uburyo amasaha yigihe cyibizamini afitanye isano nukuri kwisi kwisi ikora bifasha abategura umushinga guhitamo neza guhuza ibimera bya aluminiyumu hamwe nudukingirizo two gukingira ibyumba byo hejuru byo ku nkombe .

Ubukanishi bwa ruswa muri zone yinyanja

Uturere two ku nkombe dushiraho ibidukikije bikaze byubaka ibyuma kubera imyunyu yo mu kirere hamwe nikirere cyo mu nyanja.

Igitero cya Chloride yo mu kirere hamwe nubukanishi

Nubwo aluminiyumu isanzwe ikora urwego rukingira (Al₂O₃), ibitonyanga byumunyu wa microscopique bitera ibitonyanga bya chloride ion (Cl-) hejuru yicyuma. Izi ion za chloride zinjira mubintu bidakomeye muri firime ya oxyde, bigakora ingirabuzimafatizo za galvanike ziganisha ku mwobo no kwangirika hejuru.

Amagare yubushyuhe bwo gusiganwa ku magare no munsi ya firime

Iyo umuyaga wo mu nyanja uhujwe nubushyuhe buri hejuru ugereranije, firime yoroheje iba hejuru yicyuma, ikora nka electrolyte ikomeza. Niba ubuhehere bwinjiye munsi y irangi ryangiritse, bitera kwangirika munsi ya firime (filiform corrosion), bigakora inzira-yigitagangurirwa-imeze nkurubuga rwizamura irangi muri aluminiyumu.

Core B2B Porogaramu Yumunyu-Kurwanya Aluminium Igisenge

Kugaragaza umunyu-spray wapimwe aluminiyumu ni ingenzi mubice byinshi byubaka inyanja:

Ibibazo

Q1: Nibihe bangahe byo gupima umunyu ukenera ibisenge byashyizwe muri metero 500 uvuye ku nyanja?

Igisubizo: Imishinga iri muri metero 500 yo kumena surf igomba kwerekana byibuze amasaha 3.000  ya ASTM B117 itabogamye. Uru rutonde rusanzwe rugerwaho hifashishijwe 5052 alloy substrate ihujwe na kote- 70% PVDF cyangwa sisitemu yo gusiga amarangi.

Q2: Kuki ibyuma byateguwe mbere byananiranye byihuse kuruta aluminiyumu yanditswe mbere muri zone yinyanja?

Igisubizo: Icyuma gishingiye ku gitambo cyoroshye cya zinc. Iyo umunyu wo mu nyanja umaze gutera cyangwa ukinjira mu irangi ukageza ku mbuto mbisi, igicucu cya zinc kirashonga vuba, bigatuma ingese zitukura, kunanuka mu miterere, no gusiga irangi. Ibinyuranye, aluminiyumu ikora firime irinda kwikingira irwanya ruswa.

Q3: Ni izihe ngaruka zo gukoresha abaguzi batabigenewe kubikoresho bya aluminiyumu yoroheje?

Igisubizo: Abatanga ibicuruzwa batabigenzuye barashobora gukoresha ibyiciro byo hasi cyangwa ibyitonderwa bidahuye. Ibi birashobora gutuma umuntu apfundikanya, akanyerera cyane, hamwe nicyuma kitaragera mugihe cyimyaka 2 - 5 uhereye igihe cyo gushyiramo marine.

Q4: Ese 5052 ibishushanyo mbonera bya aluminiyumu bishobora guhindurwa bikavamo imyirondoro ihagaze nta gusiga irangi?

Igisubizo: Yego, mugihe sisitemu yo gutwikira fluoropolymer yashyizweho kugirango ihindurwe (1T - 2T igipimo cyerekana). Ibi bituma urupapuro rwabugenewe rushyirwaho muburyo bukomeye butarinze gufunga ikoti irinda micro.

Q5: Nigute Changzhou Dingang Metal Material Co., Ltd. (Ubushinwa) yemeza ko gufatira kuri aluminium yo mu nyanja?

Igisubizo: Dingang Metal Material Co., Ltd ikoresha ibyiciro byinshi byo gusukura imiti no guhinduranya imirongo mbere yo gushushanya. Ibi birema ubuso busukuye hamwe nimbaraga zo hejuru (38 mN / m), bigashyiraho umubano ukomeye hagati ya substrate ya aluminium na primer-inginging primer.

Umwanzuro

Guhitamo ibikoresho byo gusakara kubidukikije ku nkombe bisaba kuringaniza guhitamo amavuta, ubwiza bwo kwitegura, hamwe na chimie ya sisitemu. Mugaragaza 3000 cyangwa 5000 ya aluminium substrate hamwe nibikorwa byerekana amasaha 3.000+  yo gutera umunyu, amatsinda yumushinga arashobora kurinda inyanja yinyanja kunanirwa imburagihe kandi akemeza ko igihe kirekire cyubatswe.
