Gutesha Icyiciro A ni iki? Kuberiki Isukura Ubuso Bwuzuye kubintu bipfunyitse

Ku bayobozi ba C-suite, abayobozi bashinzwe amasoko ku isi, hamwe n’abashinzwe gupakira ibicuruzwa mu nganda z’ibiribwa, imiti, n’ubuhanga bwo guhindura tekinike, ubuziranenge bw’ibikoresho ni ishingiro ry’ibicuruzwa byiza. Mubikorwa bihoraho byo guhindura-nka lacquering, coat-coater coating, cyangwa extrait laminating - ndetse no kwanduza microscopique hejuru yanduye bishobora gutera kunanirwa kwangiza, gusibanganya, no kwibuka ibicuruzwa.

Ibipimo nganda byubuziranenge bwubutaka ni Kugabanya Icyiciro A (kizwi kandi nka Brush Water Grade A cyangwa Amazi Wettability Grade A ). Ubu buryo bwa tekinike bwemeza ko ifu ya aluminiyumu idafite amavuta yuzuye, ibisigazwa by’ibinyabuzima, hamwe n’ibyanduza, bitanga ubuso bw’ingufu nyinshi zisabwa kugira ngo hafatwe neza kandi hubahirizwe umutekano.

Ibisabwa Byibanze Ibisabwa kugirango uhindurwe neza

Imirongo yihuta yihuta hamwe na laminating ikora muburyo bwo kwihanganira imashini. Amavuta yo hejuru atamenyekanye kuri aluminiyumu mbisi ahagarika guhuza imiti, bikavamo ibikoresho bihenze.

Amavuta asigara asigaye nkimpamvu yibanze yo gutwikira

Mugihe cyo gukonjesha ubukonje, amavuta yo kwisiga menshi hamwe namavuta azunguruka bikoreshwa mukugabanya fayili ya aluminiyumu kugeza ku gipimo cyoroheje (kugeza kuri 0.006mm - 0.08mm ). Niba aya mavuta ya hydrocarbone adasukuwe neza mugihe cyo kwisiga cyangwa gusukura imiti, firime yoroheje, hydrophobique iguma hejuru yicyuma.

Gusobanura Isuku Yubuso: Kuki Bare Ibyiza Byerekana Ipfunyika Intsinzi

Iyo polymers ikora, resinike ya epoxy-fenolike, cyangwa imiti ya polyurethane ikoreshwa kumpapuro zanduye, amavuta kama akora nkinzitizi yo guhuza imiti. Kugera ku ntera yo mu rwego rwa A byerekana neza ko ubutare bwakira neza mu buryo bwa shimi, bigatuma ibishishwa byamazi bitemba neza bitarinze gukurura, gutobora, cyangwa micro-bubbling.

Ibyingenzi Byinganda Zisaba Gusaba Impamyabumenyi Icyiciro A Foil

Kugaragaza Impamyabumenyi Icyiciro cya aluminiyumu ni ingenzi mu nganda zisaba inganda:

Ibibazo

Q1: Nigute Gutesha Icyiciro A bigenzurwa hasi muruganda?

Igisubizo : Kugenzura bikorwa hifashishijwe Ikizamini cyamazi (spray yamashanyarazi kuri ASTM B479) cyangwa Ikizamini cya Dyne (ISO 8296). Ku cyiciro cya A file, amazi yatoboye akora firime idahagarara, ikomeza hejuru ya 100%  yubuso bwageragejwe, igera ku busumbane bwubuso bwa dyn 72 dyn / cm.

Q2: Gutesha agaciro A A birashobora kugerwaho kuri feri ya aluminium ikomeye ('H')?

Igisubizo: Yego. Mugihe ifu yoroshye ('O' temper) yangiritse muburyo busanzwe mugihe cyo hejuru yubushyuhe bwo hejuru, ifu yubushyuhe itunganywa hifashishijwe imirongo ikomeza kwangiza imiti ikoresheje isuku ya alkaline, gukaraba amazi ya deioni, no guhata umuyaga ushushe kugirango ukureho amavuta azunguruka nticyoroshye icyuma.

Q3: Bigenda bite iyo uhinduye akoresheje lacquers zishingiye kuri solide hejuru ya Grade C ya aluminium?

. Igisubizo Ibi bitera pinhole, amaso-amafi, kugabanya imbaraga zubusabane, hamwe no gusibanganya mugihe cyo guhinduka.

Q4: Gutesha Icyiciro A bigira ingaruka mubuzima bwubuzima bwa aluminiyumu idashyizwe hamwe?

Igisubizo: Icyiciro A foil ntigira amavuta yo gukurura ubushuhe cyangwa ivumbi ryibidukikije. Nyamara, kubera ko ifite ubuso busukuye, igomba kubikwa ahantu hagenzurwa nubushuhe hamwe nububiko budafite ubushyuhe (nkimpapuro za VCI na desiccants) kugirango birinde ubukonje bw’amazi hamwe na okiside yo hejuru (ingese yera).

Q5: Gutesha agaciro Icyiciro ni itegeko kubipakira ibiryo?

Igisubizo: Yego. Amabwiriza y’umutekano w’ibiribwa (harimo FDA 21 CFR na EU No 10/2011) ategeka ko ibikoresho bihuza ibiryo bitagomba kwimura ibintu bitemewe mu biribwa. Ibisigazwa by'amavuta birimo hydrocarbone ishobora kwimukira mu biribwa, bigatuma Icyiciro cya A gisukuye neza inganda zikenerwa mu guhuza ibiryo.

Umwanzuro

Kugaragaza Gutesha agaciro Icyiciro cya aluminiyumu ningirakamaro mugukora neza cyane, gucapa, no kumurika. Kurandura amavuta yo hejuru yemeza neza ko bifatanye neza, bikarinda gusenyuka, kandi byemeza ko amabwiriza yubahirizwa mu biribwa, imiti, hamwe n’ikoranabuhanga ryo mu rwego rwo hejuru.
