New antibacterial okugadziridza michina nokuda Textiles

nguva:2019-08-20 Hits:

Antibacterial yekupedzisa tekinoroji ndiyo yakawandisa huwandu hwezvinyorwa zve marginal, zvinosanganisira kudhaya uye kupedzisa, makemikari enjini, mushonga, microbiology uye zvimwe zvakawanda zvinodzidziswa.Kushandiswa kweanopedza antibacterial mumachira hakugone kungogura nzira yekuparadzira uye kubereka hutachiona hutachiona hwakadai semabhakitiriya., fungi uye kuumbwa, asi zvakare dzivirira kunhuhwirira, mavara mavara uye matambudziko ehutano akakonzerwa navo.

kazhinji, kupedza antibacterial kunoreva nzira yekushandisa antimicrobial vamiriri kumafirita uye kuagadzirisa mumachira nekuturika, kuumburuka, kukwiridzira kana kupuruzira mukati mekuita kudhinda kwemachira uye dhayeti.Kuti kuvandudza tekinoroji yemachira, plasma tekinoroji, vacuum sputtering tekinoroji uye nano tekinoroji inoshandiswa zvakanyanya mukupedza antibacterial yemachira.

 

Plasma antibacterial kupedzisa

Kushandisa plasma pamusoro kurapwa kuwana antibacterial maitiro inyanzvi nyowani yekumusoro antibacterial modization.Ion implantation, ion danda rakabatsira kuburitswa (IBAD) uye plasma yakanyudzwa ion implantation deposition (piii-d) Ndedzipi nzira huru dzehunyanzvi dzekuwana antibacterial zvinhu zvemidziyo.


Ion implantation inzira yekusimudzira yakakwira-simba ion munzvimbo dzakasimba pasi pekupfeka mamiriro.Ikuisa zvimwe zvinhu zve antibacterial zvakaita saAg naCu pamusoro pezvinhu zvemachira., iyo metastable chikamu kana yekudziya chikamu inogona kuumbwa uye maantibacterial anogona kuwanikwa. Iyo nzira ine mukana wekugadzirisa dambudziko rekubatana pakati pekurongedza nzvimbo uye substrate yakagadziriswa nemamwe maitiro.Ion danda rakaburitswa deposition rudzi rwemhando yezvinhu zvekugadziridza tekinoroji iyo inobatanidza kuisirwa ion uye yakaonda firimu., ion marombe ane imwe huwandu hwesimba inoshandiswa kubhomba uye kusanganisa, kuitira kuti vagadzire firimu rakareruka kana rakatenderedzwa remafirimu.Iyo nzira inogona kukura mafirimu ehu chero hukoshwa achienderera nekusimba pakaderera bombardment simba uye nekurongedza mafirimu akaomarara ane akakodzera kemikari zviyero kana padyo nekamuri tembiricha.At iripo, pane mashoma tsvagiridzo pakushandiswa kwehunyanzvi uhu mune antibacterial zvinhu, uye ine mukana mukuru wekuvandudza mune ramangwana.Plasma kunyudzwa ion implantation deposition ndeye kuburitsa plasma mukamuri yekuzorora pamberi, uye wobva waisa zvisina kunaka kusarura padanho rebasa kuti uwane ion kuisirwa kana deposition, iyo ine zvese ion kuisirwa mhedzisiro uye yakajairwa ion kuiswa mhedzisiro .. Iyi nzira inogona kuvandudza chimiro chemuviri nemakemikari emafirimu uye akaumbwa zvikamu., iyo inogona kuiswa mukutsvagisa antibacterial zvinhu.

 

Vuta sirivheri-yakaiswa antibacterial kupera

Yakajairwa electroless siriya yekupedzisa maitiro ari nyore, asi kusimba, kukurumidza uye manheru hazvina kunaka.Vhavha sirivha yekurongedza kupedzisa pasi pemvura yakakwira, kune rimwe divi, inoderedza kuwirirana pakati pesiri maatomu uye magesi mamorekuru, nokudaro kuderedza kuitika kwekushanduka kwemakemikari, pane rimwe divi, inogona kuchengeta iwo emukati machena machira akachena, uye natsiridza kukurumidza kunamatira kwesilver maatomu uye firita.

Mune vacuum sirivha plating, machira haafanire kuve neunyoro, kana zvisina kudaro nzvimbo yekugezesa ichaderedzwa.Iye yekukurumidza kuomerera ndiyo kiyi yemhando yezvigadzirwa.

 

Siri yakaiswa antibacterial kupera

Kuparadzira kwemicheka kunogona kuitiswa mu2-nhanho nhanho yekuurutsira mudziyo. Mukupfira, kukurumidza kunamatira kwesimbi pane machira kuri nani pane iwo wekuteedzera mapepa.Pamwezve, chiyero chakanyorova kupora, kupisa kupisa uye hydrophilic boka remukati yemafirayisi inokanganisa chigadziro chemhedzisiro.Yakagadzirwa nekotoni uye viscose machira, polyester machira zviri nyore kupera, uye mhepo yekuwanika kwemucheka wakasarudzika machira haina kusachinjika, inoenderana nefirimu yesimbi yakaputirwa pamusoro pefibidhi yega yega, pane kuomerera pagomba refaira.Chipfekedzwa nemachira asina kurapwa, kuomarara uye kuchinjika kwemachira akapararira zvakasiyana kubva 4% kuti 24%, ndiko, zvishoma kuomesa tsika, iyo yakafanana neiyo yeiyo general resin kupedzisa uye thermeta kurapwa kurapwa.

 

Iyo nyowani zvitsva sirivheri-yakarongedzwa machira uye machira akagadziriswa nemagineti yekurongedza uye hunyanzvi hwekuumbiridza tekinoroji ine yakanakisa antibacterial zvinhu uye ndiyo yepamusoro zvinhu zvinoshandiswa kune vanopfeka zvekurapa vanopfeka zvakadai sekupisa.Nguva imwechete iyoyo, iyo sirivheri inogona kuwanda uye mucheka unogona kuparadzaniswa kubva pamagetsi emagetsi.


Inovandudzwa antibacterial kupedzisa

Kazhinji izvo antibacterial zvinhu zvemicheka zvinowanikwa nyore mukupedza, asi zvakare yakarasika nyore mukushambidza.In kuitira kuti uvandudze kusimba kweanorwisa antibacterial ekupedza micheka, regenerability yeanbacterial basa inzira yekupedzisa nzira.In ino itsva maitiro, mubereki wemhuri (angangoita antibacterial mumiriri) inotsiva iyo antibacterial mumiriri pachayo uye inoshandiswa mune yeantibacterial kurapwa kweselulose zvinhu.Nguva isati yasvika antibacterial boka, iyo inogona kurwisa antibacterial mumiriri zvakasunga zvakasunga kune cellulose zvinhu, iyo inogona kubva yashandurwa neiyo inodzoreredzwa kemakemikari maitiro (seREDOX reaction), kusunungura iro rinorwisa antibacterial group .. Iyi nzira yekupedzisa yakafanana neyakagwinya-inodzivirira kupedzisa maitiro, uye maitiro e activation anogona kuwanikwa mumisangano yakajairika senge kubhuroka.

 

Iyo inogona kuve yakanangana antimicrobial mumiriri inobvisa hydanilide, zvinoti, mono-hydroxymethyl-5, 5-dimethyl hydanilide (MDMH).Kushandisa MDMH kurapa cellulose machira, iyo hydroxymethyl muMDMH inogona kuita neboka re hydroxyl pane iyo molecose ye cellulose fiber kuti ibudise covalent bond.Ipiri amino boka muMDMH rinogona kurapwa nemhinduro ine inoshanda chlorine yekugadzira haloamine chimiro.. Iyo klorini polarity yekubatana yakasungwa mune haloamine chimiro ine yakasimba uye ine oxidation maitiro, iyo inogona kutungamira kune inactivation yehutachiona, nekudaro kuzadzisa iyo antibacterial effect.After chlorination, iyo chlorine atomu inoderedzwa kuti ive chloride, uye iyo halogen-amine bond inoshandurwa kune yechipiri amino boka, iyo inogona kugadzirwazve mushure mekunyorwa zvakare, kuitira kuti uzive kuvandudzwa kwean antibacterial basa.

 

Nanometer antibacterial zvinhu uye kushanda kwayo

Nano-antibacterial zvinhu zvinogona kukamuraniswa muzvisikwa nano-antibacterial zvinhu, organic nano-antibacterial zvinhu uye inorganic nano-antibacterial zvinhu.Nanometer sirivheri ion antibacterial mumiriri inotungamira inorganic antibacterial mumiririri, iyo inogona kuve yakafanana yakaparadzirwa mune zvigadzirwa uye isina chaiyo yakakosha pane yekugadzirisa tekinoroji, uye inogona kushandiswa zvakanyanya mumhando dzese dzezvigadzirwa zvefibri.Inovimba nekuita maitiro kuti iparadze hutachiona mabasa, uye chinhu chayo chinonzi antibacterial isiri ion, neyakagara kwenguva refu antibacterial effect.

Nenzira yekushambadza adsorption uye ion kuchinjana, iyo sirivoni ion yakarongedzwa pamusoro pemidziyo yemidziyo yakadai senzou, ceramic, silica gel uye nezvimwe kugadzira antibacterial mumiririri, uyezve nanometer, uyezve inozowedzerwa kune zvigadzirwa zvinoenderana nenzira yekudhinda machira, nyungudika kupota uye dzimwe nzira kuti uwane izvo zvinyorwa zvine antibacterial uwezo.Iyo sirivha inoumbana seiyi huru antibacterial muviri uye nano TiO2 uye SiO2 sevatakuri., iyo yakakosha mhedzisiro yeano nano powder masisitimu anovandudza zvikuru iyo yakazara antibacterial effect, kupa yakazara kutamba kune kupisa kupisa, hupfu hwakatsetseka, kupararira uye mashandiro anoshanda.
