Game da Cellulose
Cellulose wani sinadari ne mai yawan ƙwayoyin halitta wanda ya ƙunshi glucose. Yana wanzuwa a adadi mai yawa a cikin tsire-tsire masu kore da halittun ruwa. Shi ne mafi yawan rarrabawa kuma mafi girman kayan polymer na halitta a yanayi. Yana da kyakkyawan jituwa da halittu, mai sabuntawa da kuma wanda za a iya lalata shi da sauran fa'idodi. Ta hanyar photosynthesis, tsire-tsire na iya haɗa ɗaruruwan miliyoyin tan na cellulose kowace shekara.
Abubuwan da ake tsammanin amfani da Cellulose
Cellulose na gargajiya ya takaita amfani da shi sosai saboda halayensa na zahiri da na sinadarai, yayin da cellulose na kayan polymer na halitta yana da halaye daban-daban na aiki bayan sarrafawa da gyara, wanda zai iya biyan buƙatun masana'antu daban-daban. Amfani da kayan aikin cellulose na aiki ya zama yanayin ci gaba na halitta da kuma wuraren bincike na kayan polymer.
Ana samar da abubuwan da suka samo asali daga ƙwayoyin halitta ta hanyar esterification ko etherification na ƙungiyoyin hydroxyl a cikin ƙwayoyin cellulose tare da abubuwan da suka samo asali daga sinadarai. Dangane da halayen tsarin samfuran amsawa, ana iya raba abubuwan da suka samo asali daga ƙwayoyin halitta zuwa rukuni uku: ƙwayoyin cellulose, ƙwayoyin cellulose, da ƙwayoyin cellulose ether.
1. Cellulose ether
Cellulose ether kalma ce ta gabaɗaya ga jerin abubuwan da suka samo asali daga cellulose waɗanda aka samar ta hanyar amsawar alkali cellulose da wakilin etherifying a ƙarƙashin wasu yanayi. Cellulose ether wani nau'in abubuwan da suka samo asali daga cellulose ne mai nau'ikan iri daban-daban, fannoni daban-daban na aikace-aikace, yawan samarwa mai yawa da ƙimar bincike mai yawa. Amfani da shi ya ƙunshi fannoni da yawa kamar masana'antu, noma, masana'antar sinadarai ta yau da kullun, kariyar muhalli, sararin samaniya da tsaron ƙasa.
Kwayoyin cellulose da ake amfani da su a kasuwa sune: methyl cellulose, carboxymethyl cellulose, ethyl cellulose, hydroxyethyl cellulose, cyanoethyl cellulose, hydroxypropyl cellulose da hydroxypropyl methylcellulose cellulose da sauransu.
2. Cellulose ester
Ana amfani da ƙwayoyin cellulose sosai a fannonin tsaron ƙasa, masana'antar sinadarai, ilmin halitta, magani, gini har ma da sararin samaniya.
Esters ɗin cellulose da ake amfani da su a kasuwa sune: cellulose nitrate, cellulose acetate, cellulose acetate butyrate da cellulose xanthate.
3. Cellulose ether ester
Cellulose ether esters sune gaurayen ester-ether.
Aikace-aikacen filin:
1. Bangaren magunguna
Ana amfani da ƙwayoyin cellulose ether da ester sosai a fannin magani don kauri, mai taimakawa wajen narkewa, da kuma sakewa mai ɗorewa, da kuma sakewa mai sarrafawa, da kuma samar da fim da sauran dalilai.
2. Filin rufewa
Cellulose esters suna taka muhimmiyar rawa wajen amfani da shafi.Esters na CelluloseAna amfani da su a cikin abubuwan ɗaurewa, resins da aka gyara ko kayan da aka riga aka yi fim don samar da rufin da ke da kyawawan halaye masu yawa.
3. Fannin fasahar membrane
Kayan Cellulose da aka samo asali suna da fa'idodin babban fitarwa, aiki mai ɗorewa, da sake amfani da su. Ta hanyar haɗa kai-tsaye-tsaye-tsaye-tsaye, hanyar juyawar matakai, fasahar juyawar lantarki da sauran hanyoyi, ana iya shirya kayan membrane masu kyakkyawan aikin rabuwa. A fannin fasahar membrane ana amfani da su sosai.
4. Sashen gini
Kwayoyin Cellulose ethers suna da ƙarfin gel mai ƙarfi wanda za a iya jurewa ta hanyar zafi kuma saboda haka suna da amfani a matsayin ƙari a cikin abubuwan gini, kamar ƙarin manne na tayal da aka yi da siminti.
5. Tashar Jiragen Sama, sabbin motocin makamashi da na'urorin lantarki masu inganci
Ana iya amfani da kayan aikin optoelectronic masu aiki waɗanda aka gina a cikin cellulose a cikin jiragen sama, sabbin motocin makamashi da na'urorin lantarki masu inganci.
