Matakai don Yin Abin Rufe Gashi da Fasaha ta Nano
1. Binciken da tsara tsari
Matakin farko yana farawa ne daga tantance matsalar gashi da aka yi niyya, misali:
- busassun da kuma rabuwar ƙarshen,
- lalacewar gashi saboda bleaching,
- gashi mai gauraye da kuma mai kauri,
- fatar kan mutum mai laushi.
Sannan, ana tantance babban sinadarin aiki, amincin yawansa, da tsarin isar da shi. A wannan matakin, yawanci ana yin nazarin daidaiton abu: ko sinadarin aiki yana da karko a takamaiman pH, ko yana haɗuwa da wasu surfactants, da kuma yadda yake shafar danko.
2. Shiri na matakin ruwa da kuma matakin mai
– Matakin ruwa: Ana dumama ruwan da aka narkar da shi kaɗan (misali 40–70°C ya danganta da kayan), sannan a ƙara wasu humectants da thickenders har sai ya narke.
– Matakin mai: ana dumama mai/ester da kayan lipophilic zuwa irin wannan zafin don rage danko da kuma sauƙaƙa haɗawa.
Dumamawa tana taimakawa wajen samar da sinadarin emulsion mai ƙarfi, amma dole ne a sarrafa shi ta yadda sinadaran da ke aiki (misali wasu bitamin ko abubuwan da aka cire) ba za su lalace ba.
3. Tsarin kafin emulsification
Ana zuba man a hankali a cikin matakin ruwa (ko akasin haka, ya danganta da ƙirar), sannan a haɗa shi ta amfani da mahaɗin mai kauri don samar da emulsion na farko. A wannan matakin, ɗigon har yanzu suna da girman micrometer.
Kyakkyawan pre-emulsion zai sauƙaƙa matakin girman nano na gaba kuma ya rage haɗarin rabuwar lokaci.
4. Girman Nano
Don rage ɗigon ruwa zuwa nanoscale, ana amfani da fasahohi da yawa akai-akai:
– Haɗakarwa mai ƙarfi (HPH): ana tilasta emulsion ta cikin wani kunkuntar rata a babban matsin lamba don ɗigon ya karye zuwa ƙananan guntu.
– Ultrasonication: raƙuman ultrasonic suna rushe ɗigon ruwa ta hanyar abin da ke faruwa na cavitation.
– Microfluidization: yayi kama da HPH amma tare da ingantaccen sarrafa kwararar micro-flow.
Zaɓin fasaha ya dogara ne da ƙarfin samarwa, farashi, da girman barbashi da aka yi niyya. Wannan tsari yawanci ana yinsa ne a cikin zagaye da dama har sai girman ɗigon ruwa da rarrabawa sun cika ƙa'idodi.
5. Sanyaya da ƙara kayan da ke da laushi
Da zarar an kai matakin nanoscale, samfurin yana sanyaya a hankali. Sinadaran da ke da tasiri ga zafi (kamar wasu abubuwan cirewa, turare, ko wasu abubuwan kiyayewa) galibi ana ƙara su a lokacin sanyaya don kiyaye inganci.
A wannan matakin, ana kuma daidaita pH ɗin don dacewa da gashi da fatar kai. Yawancin kayayyakin gashi suna da ɗan acidic pH (kusan 4-6) don taimakawa wajen rufe cuticle ɗin da rage frizz, kodayake ainihin pH ya dogara da dabarar.
6. Saitunan rubutu da kwanciyar hankali na ƙarshe
Ya kamata abin rufe gashi ya kasance yana da laushi mai daɗi: ba ya yin ruwa sosai, ba ya yin kauri sosai, yana da sauƙin rarrabawa, kuma yana da sauƙin wankewa. Ana iya daidaita abubuwan kauri, abubuwan da ke ƙara ƙamshi, ko abubuwan da ke sanyaya gashi. Idan ɗanɗano ya yi yawa, sakin sinadaran da ke aiki zai iya kawo cikas; idan ya yi ƙasa sosai, mai amfani zai ji "bai isa wadata ba" kuma samfurin zai diga cikin sauƙi.
7. Marufi wanda ke tallafawa daidaito
Nanotechnology sau da yawa yana buƙatar ƙarin kulawa ga marufi:
- kwantena dole ne su kasance masu jituwa kuma ba sa amsawa,
- rufewa mai ƙarfi don hana gurɓatawa,
– da kyau marufi yana rage fallasa ga iska da haske.
A cikin samfuran da suka fi tsada, ana amfani da kwalba masu murfi na ciki ko tsarin da ba shi da iska don rage yawan iskar oxygen.
Gwajin Inganci da Gwajin Tsaro
Don tabbatar da cewa samfurin ya dace da amfani kuma yana da aminci, wasu muhimman gwaje-gwaje sun haɗa da:
– Girman barbashi da rarrabawa (binciken girman barbashi/DLS): yana tabbatar da cewa tsarin yana kan girman da aka nufa kuma baya taruwa cikin sauƙi.
– Kwanciyar hankali ta jiki: gwajin centrifugation, gwajin keke (zafi-sanyi), ajiya na wani lokaci don ganin rabuwar lokaci.
- pH da danko: dole ne su kasance daidai tsakanin batches.
- Gwaje-gwajen ƙwayoyin cuta: jimlar adadin faranti, gwajin ingancin kiyayewa.
– Gwajin ƙaiƙayi na fata (gwajin faci) da kuma kimanta aminci: musamman ga fatar kai mai laushi.
Idan za a tallata wani samfuri, ana kuma buƙatar masana'antun su bi ƙa'idodin kayan kwalliya da ake aiki da su a ƙasar, gami da takardun dabarun samfura da iƙirari.
Kalubale a Samar da Mashin Gashi na Nano
Duk da cewa akwai kyakkyawan fata, haɓaka abin rufe fuska na nano yana da ƙalubale:
- Babban farashin kayan aiki da samarwa (HPH/microfluidizers ba su da arha).
- Kwanciyar hankali na dogon lokaci na iya zama mai rikitarwa; girman nanoscale yana iya canzawa idan tsarin surfactant bai dace ba.
- Dole ne a tabbatar da ikirarin tallatawa da shaidu; "nano" ba yana nufin gyara gashi na dindindin ba ta atomatik.
– Fahimtar masu amfani: Wasu masu amfani suna damuwa da kalmar nano. Saboda haka, bayyana gaskiya game da aminci da gwaji yana da matuƙar muhimmanci.
