Starch ether da cellulose ether duka nau'ikan nau'ikan ether ne da ake amfani da su a masana'antu daban-daban, musamman a cikin gini da sutura.Yayin da suke raba wasu kamanceceniya dangane da kasancewar su polymers masu narkewar ruwa tare da kauri da daidaita kaddarorin, akwai bambance-bambance na asali a tsakanin su, da farko a tushen su da tsarin sinadarai.
Sitaci Ether:
1. Tushen:
- Asalin Halitta: An samo sitaci ether daga sitaci, wanda shine carbohydrate da ake samu a cikin tsire-tsire.Ana yawan fitar da sitaci daga amfanin gona kamar masara, dankali, ko rogo.
2. Tsarin Sinadari:
- Abun Haɗin Polymer: Sitaci shine polysaccharide wanda ya ƙunshi raka'o'in glucose mai alaƙa da haɗin gwiwar glycosidic.Sitaci ethers an gyaggyara abubuwan sitaci, inda ƙungiyoyin hydroxyl akan kwayoyin sitaci suke maye gurbinsu da ƙungiyoyin ether.
3. Aikace-aikace:
- Masana'antar Gina: Ana yawan amfani da ethers na sitaci a cikin masana'antar gini azaman ƙari a cikin samfuran tushen gypsum, turmi, da kayan tushen siminti.Suna ba da gudummawa ga ingantaccen aiki, riƙe ruwa, da mannewa.
4. Nau'o'in gama-gari:
- Hydroxyethyl Starch (HES): Ɗaya daga cikin nau'in sitaci na yau da kullum shine sitaci na hydroxyethyl, inda aka gabatar da ƙungiyoyin hydroxyethyl don gyara tsarin sitaci.
Cellulose Ether:
1. Tushen:
- Asalin Halitta: Cellulose ether an samo shi daga cellulose, polymer na halitta da aka samu a cikin ganuwar tantanin halitta.Babban sashi ne na ganuwar kwayoyin halitta kuma ana fitar da shi daga tushe kamar ɓangaren itace ko auduga.
2. Tsarin Sinadari:
Abun Haɗin Polymer: Cellulose polymer ne na layi wanda ya ƙunshi raka'o'in glucose wanda aka haɗa ta β-1,4-glycosidic bonds.Cellulose ethers sune abubuwan da suka samo asali na cellulose, inda ƙungiyoyin hydroxyl a kan kwayoyin halitta na cellulose suka canza tare da ƙungiyoyin ether.
3. Aikace-aikace:
- Masana'antar Gina: Ethers cellulose suna samun amfani da yawa a cikin masana'antar gini, kama da sitaci ethers.Ana amfani da su a cikin samfuran tushen siminti, tile adhesives, da turmi don haɓaka riƙe ruwa, iya aiki, da mannewa.
4. Nau'o'in gama-gari:
- Hydroxyethyl Cellulose (HEC): Wani nau'in ether na yau da kullun shine hydroxyethyl cellulose, inda aka gabatar da ƙungiyoyin hydroxyethyl don gyara tsarin cellulose.
- Methyl Cellulose (MC): Wani nau'in na kowa shine methyl cellulose, inda aka gabatar da kungiyoyin methyl.
Mabuɗin Bambanci:
1. Tushen:
- An samo sitaci ether daga sitaci, carbohydrate da ake samu a cikin tsire-tsire.
- Cellulose ether yana samuwa ne daga cellulose, wani babban sashi na ganuwar tantanin halitta.
2. Tsarin Sinadari:
- Tushen polymer don sitaci ether shine sitaci, polysaccharide wanda ya ƙunshi raka'a glucose.
- Tushen polymer don ether cellulose shine cellulose, polymer mai layi wanda ya ƙunshi raka'a glucose.
3. Aikace-aikace:
- Ana amfani da nau'ikan ethers guda biyu a cikin masana'antar gini, amma takamaiman aikace-aikacen da ƙira na iya bambanta.
4. Nau'o'in gama-gari:
- Hydroxyethyl sitaci (HES) da hydroxyethyl cellulose (HEC) su ne misalan waɗannan abubuwan ether.
yayin da sitaci ether da cellulose ether ne duka ruwa-soluble polymers amfani da additives a daban-daban aikace-aikace, tushen su, tushe polymer, da takamaiman sinadaran Tsarin bambanta.Waɗannan bambance-bambancen na iya yin tasiri ga ayyukansu a cikin takamaiman tsari da aikace-aikace.
