Gutezimbere tekinoloji yumusaruro wuruhu rwibidukikije rukora uruhu rushingiye kuri polyurethane ikomeye yo mumazi.

Uruhu rwa polyurethane rukora ni ibintu bishya bigamije guhuza ibintu byateye imbere vuba mumyaka yashize.Yakozwe hashingiwe ku gutwikira polyurethane slurry hamwe nuburyo bwimikorere ya selile ifunguye munsi yimyenda yimyenda idoda.Nyamara, ibyinshi muri polyurethanes bikoreshwa bishingiye kumashanyarazi, kandi kwangiza ibidukikije numubiri wumuntu byatewe n ibisigisigi bya DMF hamwe na VOC ihindagurika mubikorwa byakozwe byahindutse icyuho cya tekiniki kibuza iterambere ryinganda.Kugeza ubu, polyurethane ishingiye ku mazi ni umusemburo mwiza wa polyurethane ushingiye, ariko inenge zayo ni ibintu bike, ibintu bitameze neza ku mubiri, gufatana mu buryo bworoshye hejuru y’igitwikirizo, kurwanya hydrolysis nke, guhindagurika gahoro gahoro mu gutunganya umusaruro, no gutanga umusaruro muke gukora neza.
Hashingiwe ku gitekerezo cyo "kurengera icyatsi n’ibidukikije" no kuzamura agaciro kongerewe ku bicuruzwa, umushinga wateje imbere uburyo bushya bw’ikoranabuhanga bwo gukora umusaruro wa polyurethane ukomeye kandi w’amazi hamwe n’uruhu rw’ibinyabuzima rushobora gusimbuza polyurethane.Ibintu byinshi bifite amazi meza polyurethane yateguwe kandi yatejwe imbere birashobora kugabanya ibisigisigi bya DMF hamwe na VOC ihindagurika bituruka kumasoko yiterambere mugihe bitezimbere imikorere.Mugihe kimwe, kubera ko firime irimo umubare munini wamatsinda ya hydrophilique hamwe na microporome yubatswe, igifuniko gifite umwuka mwiza nubushuhe bworoshye, kandi nigicuruzwa nyacyo.Byongeye kandi, polyurethane ihindurwa hamwe nibikoresho bya nano kugirango bitezimbere imikorere yimikorere myinshi kandi ikora cyane ya polyurethane yubukorikori bwuruhu ikwiranye nisoko, kugirango hongerwe agaciro kongererwa ibicuruzwa no gushimangira isoko.
Ibyingenzi byubushakashatsi:
(1) Tekinoroji yo gutegura ibintu byinshi bikomeye birimo amazi ya polyurethane.Ukurikije imibare yimibare yubucucike bwibintu bya serefegitura, hateguwe ibintu byinshi bihamye byo mu mazi ya polyurethane hamwe nubunini buke bwo gukwirakwiza.Ingano-nini-nini yingero zo gukwirakwiza irashobora kunoza ibintu bikomeye byo kwisiga bitarinze kwiyongera cyane.Ikibazo cyo kwijimisha cyane no gukomera mukubyara umusaruro mwinshi wa polyurethane ukomoka kumazi.Ibirimo bikomeye ni> 50%, impande zifatika za firime ni 101.1 °, kandi kurwanya amazi no kurwanya hydrolysis biratera imbere.
(2) Gukora tekinoroji ya polyurethane ikomoka kumazi.Hashingiwe ku bintu byinshi bikomeye byo mu mazi polyurethane, hatoranijwe uburyo bwo kubira umubiri hamwe n’imiti byatoranijwe kugirango habeho amazi ashingiye ku mazi ya polyurethane hamwe na selile ishobora guhinduka.Ibicuruzwa ni pompe, umubyimba kandi woroshye, hamwe no kwinjiza neza neza no gutwarwa neza, kugera kuri zeru zeru VOC na DMF mubikorwa byumusaruro, kugabanya ingorane zo kuvura amaherezo no kuzigama ikiguzi cyo gukira no kuvura mugihe cyanyuma.
(3) Tekinoroji yo gutegura polyurethane ikora mumazi.Polyurethane ikoreshwa namazi menshi hamwe na hydrophobique super, kwambara no kurwanya anti-static byateguwe hifashishijwe uburyo bwo gukanda "mercapto monoene", nanotehnologiya hamwe nubuhanga bwo gukiza urumuri.Irashobora gukoreshwa muruhu rwubukorikori, gutwikira imyenda, gutandukanya amavuta-amazi, gukingira electromagnetic nindi mirima.
