Ma cellulose ethers ndi gulu lofunika kwambiri lazochokera ku polima zachilengedwe, zomwe zimagwiritsidwa ntchito kwambiri m'mafakitale ambiri komanso m'minda. Ma cellulose ethers ndi zinthu zosinthidwa za cellulose zomwe zimapangidwa pophatikiza mapadi achilengedwe ndi ma ether compounds kudzera pamachitidwe amankhwala. Malinga ndi zolowa m'malo osiyanasiyana, ma cellulose ether amatha kugawidwa kukhala methyl cellulose (MC), hydroxypropyl methyl cellulose (HPMC), carboxymethyl cellulose (CMC) ndi mitundu ina. Mankhwalawa ali ndi kukhuthala bwino, kugwirizanitsa, kupanga mafilimu, kusunga madzi, kudzoza ndi zinthu zina, choncho amagwiritsidwa ntchito kwambiri pomanga, mankhwala, chakudya, zodzoladzola, kuchotsa mafuta, kupanga mapepala ndi mafakitale ena.
1. Makampani omanga
Ma cellulose ethers amagwira ntchito yofunika kwambiri pakupanga zida zomangira, makamaka mumatope owuma, ufa wa putty, zokutira ndi zomatira matailosi. Ntchito zake zazikulu zikuphatikiza kukhuthala, kusunga madzi, kuthira mafuta komanso kukonza bwino ntchito yomanga. Mwachitsanzo:
Kukulitsa mphamvu: Ma cellulose ether amatha kuwonjezera kukhuthala kwa matope ndi zokutira, kuwapangitsa kukhala abwino pomanga ndikupewa kugwa.
Kusungirako madzi: Pamalo owuma, ether ya cellulose imatha kusunga chinyezi, kuteteza madzi kuti asatuluke mwachangu, kuonetsetsa kuti zinthu za simenti zili ndi simenti kapena gypsum, ndikuwonjezera mphamvu zomangira ndi ntchito zakuthupi.
Limbikitsani ntchito yomanga: Ma cellulose ether amatha kupangitsa kuti zida zomangira zikhale zofewa, kuzipangitsa kukhala zosavuta kuziyika kapena kuziyika, komanso kupititsa patsogolo ntchito yomanga komanso mawonekedwe apamwamba.
2. Makampani opanga mankhwala
M'munda wamankhwala, cellulose ether imagwiritsidwa ntchito kwambiri pokonzekera mankhwala, zokutira mapiritsi, komanso zonyamula mankhwala osatha. Zomwe zimagwiritsidwa ntchito nthawi zambiri zimaphatikizapo:
Piritsi akamaumba: Cellulose ether, monga chomangira ndi disintegrant kwa mapiritsi, akhoza bwino kulimbikitsa mapangidwe mapiritsi ndi kusweka mwamsanga pamene atengedwa kuonetsetsa mayamwidwe mankhwala.
Dongosolo lomasulidwa lolamuliridwa: Ma cellulose ethers amakhala ndi zinthu zabwino zopanga filimu komanso kuwononga zinthu zomwe zimawonongeka, choncho amagwiritsidwa ntchito nthawi zambiri pokonzekera mankhwala osatha, omwe amatha kuwongolera kuchuluka kwa mankhwala m'thupi la munthu ndikutalikitsa mphamvu ya mankhwala. .
Kupaka kapisozi: Katundu wopangidwa ndi filimu ya cellulose ether imapangitsa kukhala chinthu choyenera chopaka mankhwala, chomwe chingalekanitse mankhwala ku chilengedwe chakunja, kupewa makutidwe ndi okosijeni ndi hydrolysis ya mankhwala, ndikuwonjezera kukhazikika kwa mankhwala.
3. Makampani opanga zakudya
M'makampani azakudya, ma cellulose ethers amagwiritsidwa ntchito kwambiri ngati zowonjezera, makamaka muzakudya zophikidwa, mkaka, zakumwa ndi zakudya zachisanu. Ntchito zake zazikulu ndi izi:
Thickener: Ma cellulose ether amatha kukulitsa kukhuthala kwazakudya zamadzimadzi, kusintha kakomedwe, ndikupanga zinthuzo kukhala zomangika komanso zokhuthala. Nthawi zambiri amagwiritsidwa ntchito muzakudya monga sauces, jellies, creams.
Stabilizer: Ma cellulose ethers, monga emulsifiers ndi stabilizers, amatha kuteteza bwino kulekanitsa mafuta ndi madzi muzakudya ndikuwonetsetsa kusasinthasintha ndi khalidwe la mankhwala.
Humectant: Muzakudya zophikidwa, ma cellulose ethers amatha kuthandiza mtandawo kusunga chinyezi, kupewa kutaya madzi ochulukirapo panthawi yophika, ndikuwonetsetsa kufewa ndi kukoma kwa zomwe zamalizidwa.
4. Makampani opanga zodzoladzola
Kugwiritsa ntchito ma cellulose ethers mumakampani azodzikongoletsera kumawonekera makamaka muzinthu zosamalira khungu, ma shampoos, zoyeretsa kumaso ndi zopakapaka. Ubwino wake wonyezimira, wokhuthala, kupanga mafilimu ndi kukhazikika kwake kumapangitsa kuti ikhale yofunika kwambiri pazodzikongoletsera. Mwachitsanzo:
Moisturizer: Ma cellulose ethers amatha kupanga filimu yoteteza kutseka chinyezi pakhungu ndikuthandizira kuti khungu likhale lonyowa.
Thickener: Monga chokhuthala, cellulose ether imapatsa zodzikongoletsera kusasinthasintha koyenera, kuzipangitsa kuti zikhale zosavuta kuzipaka ndi kuyamwa, ndikuwongolera luso la ogwiritsa ntchito.
Emulsifier: Ma cellulose ether amatha kukhazikika ma emulsions, kuletsa kusanja kwamadzi amafuta, ndikusunga kukhazikika kwamitundu yodzikongoletsera.
5. Makampani opanga mafuta
Kugwiritsiridwa ntchito kwa cellulose ether m'zigawo za mafuta kumawonekera makamaka pokonza madzi obowola ndi madzi ophwanyika. Cellulose ether angagwiritsidwe ntchito monga thickener, madzi kutaya kutaya ndi stabilizer kusintha ntchito pobowola madzi. Mwachitsanzo:
Thickener: Ma cellulose ether amatha kukulitsa kukhuthala kwamadzi obowola, kuthandizira kuyimitsa ndi kunyamula zodulidwa zoboola, ndikuletsa kugwa kwa khoma la chitsime.
Kuchepetsa kutaya kwamadzimadzi: Kutentha kwambiri komanso kupanikizika kwambiri, cellulose ether imatha kuchepetsa kutayika kwamadzimadzi obowola, kuteteza zigawo zamafuta ndi makoma a zitsime, ndikuwongolera kuboola bwino.
6. Makampani opanga mapepala
M'makampani opanga mapepala, cellulose ether imagwiritsidwa ntchito ngati kulimbikitsa, kupaka utoto komanso kupanga filimu pamapepala. Ikhoza kupititsa patsogolo mphamvu, gloss ndi kusalala kwa pepala ndikuthandizira kusinthasintha kusindikiza. Mwachitsanzo:
Kulimbitsa: Ma cellulose ether amatha kupititsa patsogolo mgwirizano pakati pa ulusi wa zamkati, kupanga pepala kukhala lolimba komanso lolimba.
Wopangira zokutira: Pakuyika kwa pepala, ether ya cellulose imatha kuthandizira kuti zokutira zigawidwe mofanana, kukonza kusalala komanso kusinthika kwa pepala.
Wopanga filimu: Ma cellulose ether amapanga filimu yopyapyala pamwamba pa pepala, kukulitsa kukana chinyezi komanso kulimba kwa pepala.
7. Makampani ena
Cellulose ether imagwiritsidwanso ntchito kwambiri m'mafakitale ena, monga nsalu, zikopa, zipangizo zamagetsi, kuteteza chilengedwe ndi zina. M'makampani opanga nsalu, ether ya cellulose ingagwiritsidwe ntchito popanga ulusi, kumaliza kwa nsalu ndi kubalalitsidwa kwa utoto; pokonza zikopa, cellulose ether angagwiritsidwe ntchito ngati thickener ndi ❖ kuyanika wothandizira; m'munda wa chitetezo cha chilengedwe, cellulose ether angagwiritsidwe ntchito ngati flocculant ndi adsorbent mu madzi mankhwala mankhwala zinyalala.
Monga mankhwala osinthidwa a zinthu zachilengedwe polima, mapadi ether ndi mbali yofunika kwambiri m'madera ambiri monga zomangamanga, mankhwala, chakudya, zodzoladzola, mafuta m'zigawo, papermaking, etc. ndi thickening kwambiri, kusunga madzi, filimu mapangidwe, bata ndi zina katundu. . Ndi kupita patsogolo kosalekeza kwaukadaulo, kuchuluka kwa kagwiritsidwe ntchito ka cellulose ethers kukukulirakulirabe. M'tsogolomu, ma cellulose ethers akuyembekezeka kuwonetsa kuthekera kochulukirapo komanso mtengo wogwiritsa ntchito pazinthu zobiriwira komanso zachilengedwe, zokonzekera zatsopano zamankhwala ndi zida zanzeru.
