Akwai nau'ikan cellulose da yawa, kuma menene bambancin amfanin su?

Celullulose ne mai tsari da kuma yawan polymer na halitta wanda aka samo a jikin bangon jikin tsirrai, yana samar da tallafi na tsari da tsauraran abubuwa. Ya ƙunshi raka'o'in glucose da aka haɗa tare ta hanyar haɗin β-1,4-glycosidic. Yayin da ita kanta cellulose abu ne mai kama da juna, yadda aka tsara shi da sarrafa shi yana haifar da nau'o'i daban-daban tare da kaddarorin da aikace-aikace daban-daban.

1. Microcrystalline Cellulose (MCC):

MCCana samar da shi ta hanyar magance fibers cellulose tare da acid ma'adinai, wanda ya haifar da ƙananan ƙwayoyin crystalline.
Amfani: Ana amfani dashi ko'ina azaman wakili mai girma, ɗaure, da tarwatsewa a cikin ƙirar magunguna kamar allunan da capsules. Saboda yanayin rashin aikin sa da ingantaccen matsi, MCC yana tabbatar da rarraba magunguna iri ɗaya kuma yana sauƙaƙe sakin magunguna.

2. Cellulose acetate:

Ana samun acetate cellulose ta hanyar acetylating cellulose tare da acetic anhydride ko acetic acid.
Amfani: Irin wannan nau'in cellulose ana amfani da shi sosai wajen samar da zaruruwa don yadudduka, gami da tufafi da kayan kwalliya. Ana kuma amfani da ita wajen kera matatun taba sigari, fim ɗin daukar hoto, da nau'ikan nau'ikan membranes daban-daban saboda yanayin da ba zai iya jurewa ba.

3. Ethylcellulose:

Ana samun Ethylcellulose daga cellulose ta hanyar amsawa da ethyl chloride ko ethylene oxide.
Yana amfani da: Kyawawan kaddarorin samar da fina-finai da juriya ga abubuwan kaushi na halitta suna sa ethylcellulose ya dace da allunan magunguna, yana ba da sakin sarrafa magunguna. Bugu da ƙari, ana amfani da shi wajen samar da tawada, adhesives, da kayan shafa na musamman.

4.Hydroxypropyl Methylcellulose (HPMC):

HPMCAn haɗa shi ta hanyar maye gurbin ƙungiyoyin hydroxyl na cellulose tare da ƙungiyoyin methyl da hydroxypropyl.
Amfani: HPMC yana aiki azaman mai kauri, mai daidaitawa, da emulsifier a masana'antu daban-daban, gami da abinci, kayan kwalliya, da magunguna. Ana samunsa da yawa a cikin samfuran kulawa na sirri kamar su lotions, creams, da man shafawa, da kuma a aikace-aikacen abinci kamar miya, riguna, da ice cream.

5. Sodium Carboxymethyl Cellulose (CMC):

Ana samar da CMC ta hanyar magance cellulose tare da chloroacetic acid da alkali.
Amfani: Saboda yawan narkewar ruwa da kaddarorinsa,CMCAna amfani da shi sosai azaman mai daidaitawa da ɗanƙoƙi a cikin samfuran abinci, magunguna, da aikace-aikacen masana'antu. Ana samun ta a cikin kayan gasa, kayan kiwo, man goge baki, da kayan wanke-wanke.

6. Nitrocellulose:

Nitrocellulose yana samuwa ta hanyar nitrating cellulose tare da cakuda nitric acid da sulfuric acid.
Amfani: Ana amfani da shi da farko wajen kera abubuwan fashewa, lacquers, da robobin celluloid. Nitrocellulose na tushen lacquers sun shahara a cikin kammala itace da kayan kwalliyar mota saboda bushewarsu da sauri da manyan abubuwan kyalli.

7. Kwayoyin Cellulose:

Bacterial cellulose yana hade da wasu nau'in kwayoyin cuta ta hanyar fermentation.
Yana amfani da: Abubuwan da ke da alaƙa na musamman, gami da tsafta mai ƙarfi, ƙarfi mai ƙarfi, da daidaituwar halitta, suna sa cellulose na kwayan cuta mai mahimmanci a aikace-aikacen ilimin halitta kamar su suturar rauni, kayan aikin injiniya na nama, da tsarin isar da magunguna.

Daban-daban na cellulose suna ba da aikace-aikace iri-iri a cikin masana'antu daban-daban, gami da magunguna, yadi, abinci, kayan kwalliya, da masana'antu. Kowane nau'i yana da ƙayyadaddun kaddarorin da suka sa ya dace da takamaiman amfani, kama daga samar da tallafi na tsari a cikin allunan magunguna don haɓaka nau'ikan samfuran abinci ko yin aiki azaman madadin ɗorewa a cikin fasahar kere kere. Fahimtar waɗannan bambance-bambance yana ba da damar zaɓin da aka keɓance na nau'ikan cellulose don biyan takamaiman buƙatun aiki a aikace-aikace daban-daban.
