Game da Cellulose
Cellulose shine polysaccharide macromolecular wanda ya ƙunshi glucose. Ya wanzu da yawa a cikin koren shuke-shuke da halittun ruwa. Shi ne mafi yadu rarraba kuma mafi girma na halitta polymer abu a cikin yanayi. Yana da kyawawa mai dacewa, sabuntawa da Biodegradable da sauran fa'idodi. Ta hanyar photosynthesis, tsire-tsire na iya haɗa ɗaruruwan miliyoyin ton na cellulose kowace shekara.
Hasashen Aikace-aikacen Cellulose
Cellulose na al'ada ya iyakance yawan amfani da shi saboda halayensa na zahiri da sinadarai, yayin da polymer material cellulose yana da kaddarorin aiki daban-daban bayan sarrafawa da gyare-gyare, wanda zai iya biyan buƙatu daban-daban na masana'antu daban-daban. Yin amfani da aikin kayan aikin cellulose ya zama yanayin haɓakar dabi'a da wuraren bincike na kayan polymer.
Ana samar da abubuwan da suka samo asali na cellulose ta hanyar esterification ko etherification na ƙungiyoyin hydroxyl a cikin polymers cellulose tare da sinadaran reagents. Dangane da sifofi na samfurin amsawa, ana iya raba abubuwan da suka samo asali na cellulose zuwa kashi uku: ethers cellulose, esters cellulose, da esters cellulose.
1. Cellulose ether
Cellulose ether shine kalma na gaba ɗaya don jerin abubuwan da aka samo asali na cellulose da aka kafa ta hanyar amsawar alkali cellulose da etherifying wakili a ƙarƙashin wasu yanayi. Cellulose ether wani nau'i ne na cellulose wanda ke da nau'o'in nau'i daban-daban, fa'idodin aikace-aikacen fa'ida, babban ƙarar samarwa da ƙimar bincike mai girma. Aikace-aikacen sa ya ƙunshi fannoni da yawa kamar masana'antu, aikin gona, masana'antar sinadarai ta yau da kullun, kariyar muhalli, sararin samaniya da tsaron ƙasa.
The cellulose ethers da a zahiri kasuwanci amfani ne: methyl cellulose, carboxymethyl cellulose, ethyl cellulose, hydroxyethyl cellulose, cyanoethyl cellulose, hydroxypropyl cellulose da hydroxypropyl methylcellulose Cellulose da dai sauransu.
2. Cellulose ester
Ana amfani da esters na Cellulose sosai a fagen tsaron ƙasa, masana'antar sinadarai, ilmin halitta, magani, gini har ma da sararin samaniya.
Esters cellulose da ake amfani da su a zahiri na kasuwanci sune: cellulose nitrate, cellulose acetate, cellulose acetate butyrate da cellulose xanthate.
3. Cellulose ether ester
Cellulose ether esters ne ester-ether gauraye da aka samu.
Filin aikace-aikace:
1. Filin magunguna
Ana amfani da abubuwan da aka samo asali na Cellulose da ester a cikin magani don kauri, haɓakawa, ci gaba da saki, sakin sarrafawa, ƙirƙirar fim da sauran dalilai.
2. Filin sutura
Cellulose esters suna taka muhimmiyar rawa a cikin aikace-aikacen shafa.Cellulose estersana amfani da su a cikin ɗaure, gyare-gyaren resins ko kayan fim na farko don samar da sutura tare da kyawawan kaddarorin.
3. Filin fasahar Membrane
Cellulose da kayan da aka samu suna da fa'idodin babban fitarwa, ingantaccen aiki, da sake yin amfani da su. Ta hanyar haɗin kai na Layer-by-Layer, Hanyar jujjuya lokaci, fasahar lantarki da sauran hanyoyi, ana iya shirya kayan membrane tare da kyakkyawan aikin rabuwa. A fagen fasahar membrane da ake amfani da su sosai.
4. Bangaran gine-gine
Cellulose ethers suna da babban ƙarfin juzu'i na thermally don haka suna da amfani azaman ƙari a cikin kayan aikin gini, kamar abubuwan daɗaɗɗen tayal na tushen siminti.
5. Aerospace, sababbin motocin makamashi da manyan na'urorin lantarki
Ana iya amfani da kayan aikin optoelectronic na tushen Cellulose a cikin sararin samaniya, sabbin motocin makamashi da manyan na'urorin lantarki.
