Daban-daban aikace-aikace na cellulose da abubuwan da aka samo asali

Cellulose shine polysaccharide macromolecular wanda ya ƙunshi glucose, wanda ke wanzuwa da yawa a cikin tsire-tsire masu kore 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

An yi amfani da cellulose na gargajiya da yawa saboda abubuwan da ke cikin jiki da sinadarai, yayin da polymer abu cellulose yana da kaddarorin ayyuka daban-daban bayan aiki da gyare-gyare, wanda zai iya biyan bukatun 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 esters

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.Ana amfani da esters na Cellulose a cikin ɗaure, gyare-gyaren resins ko kayan aikin 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. Filin gini

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.

6. Sauran filayen

Matsaloli da Magani a Aikace-aikacen Cellulose

A halin yanzu, cellulose har yanzu yana da wasu nakasu na asali.Saboda halaye na tsarin da aka tara, cellulose ba za a iya narke ba kuma yana da wuya a narke a cikin kaushi na al'ada, wanda ya iyakance haɓakawa da amfani da kayan cellulose.Irin su rashin ƙarfi na rashin ƙarfi a cikin kaushi na yau da kullun, rashin thermoplasticity, babban hydrophilicity da rashin kayan aikin antibacterial.

Sabili da haka, ƙira da gina sabbin kayan da aka samo daga cellulose shine tushen ingantaccen amfani da cellulose, da haɓaka fasahar rushewar cellulose mai tsabta da inganci hanya ce mai mahimmanci da garanti don ingantaccen amfani da cellulose.
