Ƙarshen ƙwayar cuta mai sabuntawa

Yawancin lokaci ana samun sauƙin ƙwayoyin ƙwayoyin cuta na yadi a cikin kammalawa, amma kuma a sauƙaƙe a ɓace a cikin wankewa.Domin inganta ƙarfin ƙarewar ƙwayoyin cuta na kayan yadi, sake farfadowa da aikin ƙwayoyin cuta sabuwar hanya ce ta ƙarshe.A cikin wannan sabon tsari, mahallin mahaifa (m antibacterial wakili) ya maye gurbin wakili na rigakafi da kansa kuma ana amfani dashi a cikin maganin maganin rigakafi na kayan cellulose. Kafin a kunna ƙungiyar maganin rigakafi, mai yuwuwar wakili na ƙwayoyin cuta yana haɗawa da kayan cellulose, wanda za'a iya kunna shi ta hanyar tsarin sinadarai mai juyawa (kamar REDOX dauki), sakewa ƙungiyar ƙwayoyin cuta.Wannan hanyar gamawa tayi kama da tsarin gamawa mai jure wrinkle, kuma ana iya samun amsawar kunnawa a cikin matakai na al'ada kamar bleaching.

 

Mai yuwuwar wakili na antimicrobial shine abin da aka samu na hydanilide, wato, mono-hydroxymethyl-5, 5-dimethyl hydranilide (MDMH).Yin amfani da MDMH don magance masana'anta cellulose, hydroxymethyl a cikin MDMH zai iya amsawa tare da ƙungiyar hydroxyl akan jerin kwayoyin halitta na fiber cellulose don samar da haɗin gwiwa.. Polarity na chlorine na covalent bond a cikin tsarin haloamine yana da ƙarfi sosai kuma yana da tasirin oxidation., wanda zai iya haifar da rashin aiki na ƙwayoyin cuta, don haka samun sakamako na antibacterial.Bayan chlorination, chlorine atom ya rage zuwa chloride, kuma haɗin halogen-amine yana canzawa zuwa rukunin amino na biyu, wanda za'a iya sabuntawa bayan an sake sanya sinadarin chlorin, don gane farfadowar aikin antibacterial.

 

Nanometer antibacterial abu da aikace-aikace

Ana iya raba kayan Nano-antibacterial zuwa kayan nano-antibacterial na halitta, Organic nano-antibacterial kayan da inorganic nano-antibacterial kayan.Nanometer silver ion wakili na antibacterial yana taka muhimmiyar rawa a cikin inorganic antibacterial wakili, wanda za'a iya tarwatsawa daidai gwargwado a cikin samfuran kuma ba shi da buƙatu na musamman akan fasahar sarrafawa, kuma za a iya amfani da ko'ina a kowane nau'i na fiber kayayyakin.It dogara a kan lamba dauki don halakar da ƙananan ƙwayoyin cuta, kuma bangarensa na kashe kwayoyin cuta shine ion azurfa, tare da sakamako na antibacterial na dogon lokaci.

Ta hanyar adsorption ta jiki da musayar ion, ion na azurfa yana gyarawa a saman kayan da ba su da kyau kamar zeolite, yumbu, silica gel da sauransu don yin maganin rigakafi, sannan nanometer, sa'an nan kuma an ƙara shi zuwa samfurori masu dacewa ta hanyar bugu na sutura, narke kadi da sauran hanyoyin da za a samu kayan da antibacterial ikon.Tare da azurfa composite a matsayin babban antibacterial jiki da nano TiO2 da SiO2 a matsayin masu dako, na musamman sakamako na nano foda barbashi ƙwarai inganta overall antibacterial sakamako, ba da cikakken wasa ga juriya na zafin jiki, foda fineness, watsawa da tasirin aiki.
