Imiterere ya TPU Film idapfa amazi kandi idashobora kunyerera mu mazi

Imikorere y'ingenzi yaFilimi ya Thermoplastic Polyurethane (TPU)Ifite ubushobozi budasanzwe bwo kwirinda amazi no kwemerera amazi kwinjira mu mazi—ishobora kubuza amazi kwinjira mu mazi mu gihe ireka molekile z’umwuka w’amazi (ibyuya, ibyuya) zigacamo.

1. Ibipimo ngenderwaho n'Amahame ngenderwaho mu Mikorere

1. Kudapfa amazi (Guhangana n'umuvuduko wa hydrostatic):
   • Ikimenyetso: Gipima ubushobozi bwa firime bwo kurwanya umuvuduko w'amazi wo hanze, upimwe muri kilopascals (kPa) cyangwa milimetero z'inkingi y'amazi (mmH₂O). Agaciro ko hejuru kerekana imikorere ikomeye yo kudapfa amazi. Urugero, imyenda isanzwe yo hanze ishobora gukenera ≥13 kPa, mu gihe ibikoresho by'umwuga bishobora gukenera ≥50 kPa.
   • Igipimo ngenderwaho cy'igerageza: Gikunze gupimwa hakoreshejwe ISO 811 cyangwa ASTM D751 (Uburyo bwo Gutera Imbaraga). Ibi bisaba kongera umuvuduko w'amazi ku ruhande rumwe rwa firime kugeza igihe amazi agaragara ku rundi ruhande, bikandika agaciro k'umuvuduko kuri iyo ngingo.
2. Ubushobozi bwo kwemerera ubushuhe (Ihererekanya ry'umwuka ushyushye):
   • Ikimenyetso: Gipima uburemere bw'umwuka w'amazi unyura mu gice cy'agace k ...
   • Igipimo cy'Ikizamini: Hari uburyo bubiri bw'ingenzi:
     • Uburyo bwo Gukoresha Igikombe Gihagaze (Uburyo bwo Gukoresha Ikinyabiziga): urugero, ASTM E96 BW. Akantu ko gusukura gashyirwa mu gikombe, gafunze neza hakoreshejwe agapfukamunwa, hanyuma ingano y'umwuka w'amazi winjira mu gihe cy'ubushyuhe n'ubukonje runaka irapimwa. Ibisubizo byegereye imiterere nyayo yo kwangirika.
     • Uburyo bwo Gukoresha Igikombe Kidahinduka (Uburyo bwo Gukoresha Amazi): urugero, ISO 15496. Amazi ashyirwa mu gikombe, gihinduka gifunze neza gikoresheje agapfundikizo, hanyuma ingano y'umwuka w'amazi uva muri icyo gikoresho irapimwa. Ubu buryo ni bwihuse kandi bukunze gukoreshwa mu kugenzura ubuziranenge.

2. Ihame ry'imikorere

Imiterere y'amazi n'ubushuhe bwo kwinjira mu maziFilime ya TPUNtibigerwaho binyuze mu myenge ifatika ahubwo bishingiye ku gikorwa cy’urwego rwa molekile rw’ibice byayo bikunda gukurura amazi:

• Idapfa amazi: Filimi ubwayo ni nini kandi nta mwenge irimo; amazi y'amazi ntashobora kunyuramo bitewe n'ubushyuhe bwayo n'imiterere ya molekile ya filimi.
• Ubushuhe Bushobora Kwemerwa: Polymeri irimo amatsinda akunda amazi (urugero, -NHCOO-). Aya matsinda "afata" molekile z'umwuka w'amazi zihinduka zikava mu ruhu imbere. Hanyuma, binyuze mu "guhinduka kw'ibice" by'iminyururu ya polymer, molekile z'amazi "zikwirakwizwa" intambwe ku yindi ziva imbere zijya hanze.

3. Uburyo bwo gupima

1. Igipimo cy'umuvuduko ukomoka ku mazi: Gikoreshwa mu gupima neza umuvuduko ntarengwa w'icyuma cyangwa umwenda.
2. Igikombe cyo Gupima Ubushuhe: Gikoreshwa mu cyumba gifite ubushyuhe n'ubushuhe buhoraho kugira ngo gipime igipimo cyo gukwirakwiza umwuka w'ubushuhe (MVTR) hakoreshejwe uburyo bw'igikombe gihagaze cyangwa gihinduriwe.

4. Porogaramu

Gukoresha iyi mitungo,Filime ya TPUni amahitamo meza kuri porogaramu nyinshi zo ku rwego rwo hejuru:

• Imyambarire yo hanze: Ibigize ingenzi mu makoti akomeye, imyenda yo ku rubura, n'amapantaro yo gutembera mu misozi, bituma abakunzi bo hanze bumira kandi bugatuma bamererwa neza mu gihe cy'umuyaga n'imvura.
• Uburinzi mu buvuzi: Bukoreshwa mu myenda yo kubaga no mu myenda yo kwirinda amaraso n'amazi yo mu mubiri (arinda amazi) mu gihe butuma ibyuya biva mu bakozi bo kwa muganga bisohoka, bigagabanya ubushyuhe.
• Imyambaro yo kuzimya inkongi no kwitoza igisirikare: Itanga uburinzi mu bidukikije bikomeye, isaba ubudahangarwa ku muriro, amazi, n'imiti, hamwe no guhumeka neza kugira ngo ikomeze kugenda no gukora neza.
• Ibikoresho by'inkweto: Bikoreshwa nk'amakanzu adapfa amazi (booties) kugira ngo ibirenge bigume byumye mu gihe cy'imvura kandi birinde ubushyuhe bw'imbere n'ubushuhe.

Muri make, binyuze mu miterere yayo yihariye y’umubiri n’imiti, filime ya TPU ihuza neza n’ibikenewe bisa nkaho bivuguruzanya nk’ “bidashobora gutwarwa n’amazi” n’ “bishobora guhumeka,” bigatuma iba igikoresho cy’ingenzi mu bijyanye n’imyenda ikora neza cyane.
