Amazi ya TPU Amazi Yumuyaga nubushuhe-Byemewe

Imikorere yibanze yaFilime ya Thermoplastique Polyurethane (TPU)iri mu miterere yayo idasanzwe y’amazi adashobora gukoreshwa n’amazi-irashobora kubuza amazi y’amazi kwinjira mu gihe yemerera molekile ziva mu mazi (ibyuya, ibyuya) kunyuramo.

1. Ibipimo byerekana imikorere

1. Amashanyarazi (Hydrostatic Pressure Resistance):
   • Icyerekana: Gupima ubushobozi bwa firime yo kurwanya umuvuduko wamazi yo hanze, upimye muri kilopascal (kPa) cyangwa milimetero yinkingi yamazi (mmH₂O). Agaciro kari hejuru yerekana imbaraga zidafite amazi. Kurugero, imyenda isanzwe yo hanze irashobora gusaba ≥13 kPa, mugihe ibikoresho-byumwuga bishobora gusaba k50 kPa.
   • Ikizamini gisanzwe: Mubisanzwe bipimishwa ukoresheje ISO 811 cyangwa ASTM D751 (Uburyo bukomeye). Ibi birimo guhora wongera umuvuduko wamazi kuruhande rumwe rwa firime kugeza ibitonyanga byamazi bigaragara kurundi ruhande, bikandika agaciro k'umuvuduko icyo gihe.
2. Ubushuhe bw'amazi (Kohereza imyuka):
   • Icyerekezo: Gupima ubwinshi bwumwuka wamazi unyura mubice bya firime mugihe cyumwanya, bigaragarira muri garama kuri metero kare kumasaha 24 (g / m² / 24h). Agaciro kari hejuru yerekana guhumeka neza no gutandukana ibyuya. Mubisanzwe, agaciro karenze 5000 g / m² / 24h gafatwa nkigihumeka cyane.
   • Ikizamini: Uburyo bubiri bwingenzi burahari:
     • Uburyo bwiza bw'igikombe (Uburyo bwa Desiccant): urugero, ASTM E96 BW. Disiccant ishyirwa mu gikombe, igashyirwaho kashe ya firime, hanyuma hapimwa urugero rwumwuka wamazi winjiye mubushyuhe bwihariye nubushuhe. Ibisubizo byegeranye nuburyo bwo kwambara.
     • Uburyo bw'igikombe gihindagurika (Uburyo bw'amazi): urugero, ISO 15496. Amazi ashyirwa mu gikombe, kigahinduka kandi kigafungwa na firime, hanyuma hapimwa ingano y'amazi y'umwuka uva muri firime. Ubu buryo burihuta kandi bukoreshwa kenshi mugucunga ubuziranenge.

2. Ihame ry'akazi

Amashanyarazi adafite amazi nubushuhe-bworoshye bwaFilime ya TPUntibigerwaho binyuze mu byobo bifatika ariko bishingiye kubikorwa bya molekuline-urwego rwibice bya hydrophilique:

• Amashanyarazi: Filime ubwayo ni yuzuye kandi idafite pore; amazi y'amazi ntashobora kunyura kubera uburemere bwayo hejuru hamwe na molekile ya firime.
• Ubushuhe bwemewe: polymer irimo amatsinda ya hydrophilique (urugero, -NHCOO-). Aya matsinda "gufata" molekile zamazi ziva mu ruhu imbere. Noneho, binyuze muri "segment movement" yiminyururu ya polymer, molekile zamazi zigenda "intambwe" intambwe-ntambwe "yanduzwa" kuva imbere ikajya hanze.

3. Uburyo bwo Kwipimisha

1. Ikizamini cya Hydrostatike: Ikoreshwa mugupima neza umuvuduko ukabije wamazi ya firime cyangwa igitambaro.
2. Igikombe cyemewe: Ikoreshwa mubushyuhe burigihe nubushyuhe bwo gupima igipimo cyogukwirakwiza umwuka wumuyaga (MVTR) ukoresheje uburyo bwigikombe bugororotse cyangwa buhindagurika.

4. Porogaramu

Gukoresha iyi mitungo,Filime ya TPUni Byahiswemo Kuri Byinshi Byanyuma-Porogaramu:

• Imyambarire yo hanze: Ibyingenzi byingenzi muri jackettes ya hardshell, kwambara ski, hamwe nipantaro yo gutembera, kurinda akuma no guhumurizwa kubakunda hanze mumuyaga nimvura.
• Kurinda Ubuvuzi: Bikoreshwa mu myenda yo kubaga hamwe n’imyenda ikingira kugira ngo uhagarike amaraso n’umubiri (utarinda amazi) mu gihe wemerera ibyuya byatewe n’abakozi b’ubuvuzi guhunga, bikagabanya ubushyuhe.
• Imyambaro yo kuzimya umuriro hamwe n’imyitozo ya gisirikare: Itanga uburinzi ahantu hakabije, bisaba kurwanya umuriro, amazi, n’imiti, hamwe no guhumeka cyane kugirango bikomeze kugenda no gukora.
• Ibikoresho by'inkweto: Byakoreshejwe nk'amasogisi adafite amazi (booties) kugirango ibirenge byume mugihe cyimvura mugihe wirinda ubushyuhe bwimbere nubushuhe.

Muri make, binyuze mumiterere yihariye yumubiri nubumashini, firime ya TPU iringaniza ubuhanga ikenera ibintu bisa nkibivuguruzanya bya "bitarimo amazi" kandi "bihumeka," bigatuma iba ibikoresho byingenzi mubijyanye nimyenda ikora cyane.
