Uruhare rwumuriro wa minerval yibikoresho muri sisitemu igezweho ya Aluminiyumu

Mu myubakire igezweho, yometse kuri aluminiyumu - cyane cyane Ibikoresho bya Aluminiyumu Ibikoresho (ACM) na Aluminium Composite Panels (ACP) - byerekanwe cyane ku ibahasha yo hejuru y’inyubako ndende, ibice by'imvura, n'ibikorwa remezo rusange. Guha agaciro imbaraga zayo zingana-uburemere, uburinganire, hamwe nuburyo butandukanye, kwambika aluminiyumu byahinduye imiterere yimijyi.  

Nyamara, umuriro wamamaye cyane kwisi yose watumye habaho ivugurura rikomeye ryimyubakire mpuzamahanga. Kubera iyo mpamvu, umutekano wambitswe ibintu byinshi ushingiye cyane kumiterere yimbere yimbere. Gusimbuza polyethylene yaka umuriro hamwe nubutare bwa minisiteri yububasha butuma umuriro utuma abubatsi naba injeniyeri ba fasade bagera ku bishushanyo mbonera bigaragara mu gihe byujuje ubuziranenge bw’umutekano w’umuriro.

Umutekano wa Kijyambere-Kuzamuka Umutekano

Guhindura kuva Polyethylene (PE) Kuri Fire-Retardant Mineral Cores

Kwisubiramo hakiri kare ACP yakoresheje ingirabuzimafatizo ya polyethylene (LDPE). Mugihe LDPE yatanze uburyo bwiza bwo guhinduka hamwe nuburemere buke, polyethylene yuzuye ni thermoplastique ikomoka kuri peteroli ishonga kandi igashya vuba iyo ihuye nubushyuhe bwinshi. Nyuma y’umuriro mwinshi mu nyubako ndende, abayobozi ba komini babujije cyangwa babuza ingirabuzimafatizo za PE ku nyubako ndende, zitegeka ko zuzuye amabuye y'agaciro, zidashobora gukongoka.

Gusobanura Ibikoresho Byubatswe

Umwanya wa kijyambere wumuriro wa aluminium igizwe nuburyo bwinshi bwa sandwich:

• Uruhu rwimbere rwa Aluminiyumu: Amabati ya aluminiyumu yuzuye neza (mubisanzwe 3003-H24 cyangwa 5052-H32) yometseho amarangi ya fluoropolymer (PVDF cyangwa FEVE).

• Amashanyarazi ya Firime: Amashanyarazi menshi ya polyolefin yomekaho ihuza uruhu rwa aluminiyumu na minerval munsi yubushyuhe bwinshi nigitutu.

• Fire-Retardant Mineral Core: Matrike yuzuye igizwe namabuye y'agaciro adashobora gukongoka avanze nigice gito cya polymer binder kugirango ikomeze guhindagurika no kuba inyangamugayo.

Ibipimo byumutekano wumuriro kwisi yose & Matrix

Kugira ngo wemererwe kwishyiriraho ibice bigezweho, umuriro-utazimya utwikiriwe na aluminiyumu yambitswe ibizamini bikorerwa ibizamini byuzuye kandi byuzuye:

Ibyingenzi Byubatswe Porogaramu ya Fire-Retardant Coated Cladding

Kugaragaza imyunyu ngugu yangiza umuriro ni ngombwa mubice byinshi bisaba inyubako:

Ibibazo

Q1: Ni irihe tandukaniro nyamukuru riri hagati yicyiciro cya FR na A2 urwego rwamabuye y'agaciro muri ACP yambaye?

Igisubizo: Ibyiciro bya FR birimo hafi 70% - 80%  byuzuza amabuye y'agaciro kandi byashyizwe mubikorwa byo kwirinda umuriro (Urwego B-s1, d0). Ibyiciro bya A2 birimo ≥ 90%  byuzuza imyunyu ngugu ya organic organique, bigatuma bidashobora gukongoka (Urwego A2-s1, d0) kandi bikwiranye nu mpande ndende cyane munsi yububiko mpuzamahanga.

Q2: Kuki kugerageza guteranya urukuta rwuzuye (nka NFPA 285 cyangwa BS 8414) bikenewe hamwe no kugerageza ikibaho?

Igisubizo: Ikizamini cyumuntu kugiti cye (nka ASTM E84) gipima ubushuhe bwumuriro mubihe byihariye. Igeragezwa ryuzuye ryiteranirizo ryerekana uburyo sisitemu yuzuye yurukuta - harimo izirinda, inzitizi zuburiri, imbaho ​​zometse kuri aluminiyumu, hamwe nuburyo bwo kubaka - yitwara hamwe mugihe cyumuriro nyawo.

Q3: Ni izihe ngaruka zo gukoresha uruhu rwa aluminiyumu rutaremejwe neza ku mabuye y'agaciro atangiza umuriro?

Igisubizo: Uruhu rwa aluminiyumu rutaremezwa rushobora kuba rufite umubyimba udahuzagurika, kuringaniza impagarara zidakwiye, cyangwa amakoti yo hepfo yinyuma. Izi nenge zirashobora gutuma umuntu asiga amavuta hejuru, gusiga irangi, cyangwa gusibanganya uruhu rwa aluminium na minerval munsi yumutwaro wumuyaga hamwe nubushyuhe bwumuriro.

Ikibazo cya 4: Ese imyunyu ngugu ishobora kubika umuriro hamwe no gufunga kugirango ushyire cassette?

Igisubizo: Yego. Amabuye y'agaciro ya minerval arashobora guhindurwa no kuzunguruka kuruhande rwinyuma (hasigara uruhu rwo hejuru rwa aluminiyumu hamwe nigice cyoroshye cyibanze) kugirango ukore panne cassette utabanje kumeneka cyangwa kubangamira urwego rwibanze rwumuriro.

Q5: Nigute Changzhou Dingang Metal Material Co., Ltd. (Ubushinwa) yemeza ko irangi ryerekana amarangi ya porogaramu ikoreshwa?

Igisubizo: Dingang Metal Material Co., Ltd. ikoresha imiti myinshi ikomeza imiti mbere yo gukoresha primers na topcoats. Igiceri cyose gihura na cross-hatch, T-bend, na MEK rub ibishishwa kugirango ibashe guhuza neza mugihe cyo kumurika no kumara igihe kirekire hanze.

Umwanzuro

Guhitamo ibikoresho byo hanze bisaba kuringaniza igishushanyo mbonera n'umutekano wubatswe. Kwinjizamo imyunyu ngugu yumuriro-ushyigikiwe na imikorere-yimikorere ya PVDF / FEVE yuzuye uruhu rwa aluminiyumu-ituma abubatsi, abateza imbere, hamwe naba injeniyeri ba fasade gukora amabahasha yinyubako agezweho yujuje ubuziranenge bw’umutekano ku isi.
