Ndi mapulasitiki ati opangidwa kuchokera ku cellulose ethers?

Ma cellulose ethers ndi gulu la ma polima osunthika komanso ogwiritsidwa ntchito kwambiri omwe amachokera ku cellulose, polysaccharide yachilengedwe yomwe imapezeka m'makoma a cell cell.Ma polima awa amadziwika ndi kusungunuka kwamadzi, biodegradability, komanso kupanga mafilimu.Ngakhale ma cellulose ethers sagwiritsidwa ntchito mwachindunji popanga mapulasitiki achikhalidwe, amagwira ntchito yofunika kwambiri m'mafakitale osiyanasiyana monga mankhwala, chakudya, zomangamanga ndi nsalu.

Ma cellulose Ethers: mwachidule
Ma cellulose ndiye polima wochuluka kwambiri padziko lapansi, ndipo zotumphukira zake, zomwe zimatchedwa cellulose ethers, amapangidwa kudzera mukusintha kwa mamolekyu a cellulose.Magwero ambiri a cellulose ndi matabwa, thonje, ndi ulusi wina wazomera.

Ma cellulose ethers akuluakulu ndi awa:

Methylcellulose (MC): Wopangidwa ndikusintha magulu a hydroxyl a cellulose ndi magulu a methyl, MC imagwiritsidwa ntchito kwambiri m'makampani azakudya, zamankhwala ndi zomangamanga.Amadziwika kuti amatha kusunga madzi, ndikupangitsa kuti ikhale yowonjezera muzogwiritsira ntchito zosiyanasiyana.

Hydroxypropylcellulose (HPC): Mu chotengera ichi, magulu a hydroxyl a cellulose amasinthidwa ndi magulu a hydroxypropyl.HPC imagwiritsidwa ntchito kwambiri muzamankhwala, zodzoladzola, ndi zinthu zosamalira anthu chifukwa chakupanga mafilimu komanso kukhuthala.

Hydroxyethyl cellulose (HEC): HEC imapezeka poyambitsa magulu a hydroxyethyl mu cellulose.Amagwiritsidwa ntchito ngati thickener, binder ndi stabilizer m'mafakitale monga zomatira, utoto ndi zinthu zosamalira anthu.

Carboxymethylcellulose (CMC): CMC imapezeka posintha gawo lamagulu a hydroxyl ndi magulu a carboxymethyl.Amagwiritsidwa ntchito kwambiri m'makampani azakudya monga thickener ndi stabilizer komanso m'makampani opanga mankhwala chifukwa cha zomatira zake.

Kugwiritsa ntchito ma cellulose ethers

1. Makampani azakudya:
Ma cellulose ethers, makamaka CMC, amagwiritsidwa ntchito kwambiri m'makampani azakudya kuti apititse patsogolo mawonekedwe, kukhazikika komanso kukhuthala kwa zinthu zosiyanasiyana monga ayisikilimu, mavalidwe a saladi ndi zinthu zophikidwa.

2. Mankhwala osokoneza bongo:
Methylcellulose ndi ma cellulose ethers amagwiritsidwa ntchito popanga mankhwala monga zomangira, zosokoneza, ndi opanga mafilimu popanga mapiritsi.

3. Makampani omanga:
HEC ndi MC amagwiritsidwa ntchito kwambiri pantchito yomanga kuti apititse patsogolo magwiridwe antchito amatope, zomatira ndi zokutira.Amathandizira kukonza magwiridwe antchito komanso kusunga madzi.

4. Zothandizira pawekha:
Ma cellulose a Hydroxypropyl ndi hydroxyethyl cellulose amapezeka muzinthu zosiyanasiyana zosamalira anthu monga ma shampoos, mafuta odzola ndi zodzoladzola, zomwe zimapereka kukhuthala komanso kukhazikika.

5. Zovala:
Ma cellulose ethers amagwiritsidwa ntchito posindikiza nsalu ndi utoto chifukwa cha kukhuthala kwawo komanso kukhazikika kwawo.

Ma cellulose ether ali ndi maubwino angapo achilengedwe:

Biodegradability:

Mosiyana ndi ma polima ambiri opangidwa, ma cellulose ethers amatha kuwonongeka, kutanthauza kuti amawonongeka kudzera munjira zachilengedwe, kuchepetsa mphamvu zawo zachilengedwe.

Mphamvu Zowonjezera:

Cellulose, zopangira za cellulose ethers, zimachokera kuzinthu zongowonjezedwanso monga matabwa ndi ulusi wa mbewu.

Chepetsani kudalira mafuta a petrochemicals:

Kugwiritsa ntchito ma cellulose ethers m'njira zosiyanasiyana kumachepetsa kudalira ma polima a petrochemical ndipo kumathandizira kuti pakhale njira yokhazikika.

Mavuto ndi mayendedwe amtsogolo

Ngakhale ma cellulose ethers amapereka zabwino zambiri, palinso zovuta zina, monga kukhazikika kwamafuta ochepa komanso kusintha komwe kungachitike pazinthu zochokera kugwero la cellulose.Kafukufuku wopitilira akuyang'ana kuthana ndi zovutazi ndikuwunika ntchito zatsopano zama cellulose ether m'malo omwe akubwera.

Ma cellulose ethers amachokera ku cellulose wochulukirachulukira ndipo amagwira ntchito yofunika kwambiri m'mafakitale osiyanasiyana.Ngakhale si mapulasitiki achikhalidwe, katundu wawo amathandizira pakupanga zinthu ndi njira zokometsera zachilengedwe.Pamene mafakitale akupitiriza kufunafuna njira zina zokhazikika, ma cellulose ethers angakhalebe patsogolo pa zatsopano, kuyendetsa patsogolo pa ntchito zosiyanasiyana.
