Hydroxyethyl methylcellulose (HEMC)ndi ether ya cellulose yosakhala ionic yomwe imagwiritsidwa ntchito kwambiri m'mafakitale ambiri. Ndi ufa woyera kapena wosakhala woyera wopangidwa kuchokera ku zinthu zachilengedwe za polima - thonje loyengedwa kudzera mu zochita za mankhwala monga alkalizing ndi etherification. Ili ndi madzi abwino osungunuka, kusunga madzi, kupanga filimu, kukhuthala, emulsification komanso kukhazikika.
1. Kugwiritsa ntchito mumakampani omanga
Hydroxyethyl methylcellulose imagwiritsidwa ntchito kwambiri mumakampani omanga, makamaka pazinthu zopangidwa ndi matope ouma, zomwe zimawonekera kwambiri m'mbali zotsatirazi:
Kusunga madzi mwamphamvu: Mukawonjezera HEMC ku simenti kapena zinthu zopangidwa ndi gypsum, magwiridwe ake osunga madzi amatha kukwera kwambiri, kupewa kutayika kwa madzi ambiri, kulimbikitsa madzi a simenti, komanso kulimbikitsa kumamatira ndi mphamvu.
Kuwongolera magwiridwe antchito a zomangamanga: HEMC imatha kukonza kukhuthala ndi kugwira ntchito bwino kwa matope, kupangitsa kuti pulasitala, kuyika njerwa ndi njira zina zikhale zosavuta, kuchepetsa kumatirira kwa zida, komanso kukonza bwino ntchito yomanga.
Kapangidwe kake koletsa kugwa: Mu zinthu zomangira zoyima monga zomatira za matailosi ndi ufa wa putty, HEMC imatha kukulitsa kwambiri kapangidwe kake koletsa kugwa ndikuletsa zinthuzo kuti zisayende panthawi yomanga.
Kukhuthala: HEMC imatha kuwonjezera kukhuthala kwa matope, zomwe zimapangitsa kuti zikhale zosavuta kumamatira pamwamba pa matope, zomwe zimapangitsa kuti matopewo akhale okhuthala komanso osalala.
Konzani nthawi yogwirira ntchito: Kuonjezera nthawi yogwira ntchito, kusinthasintha kwa ntchito, ndikuthandizira kusintha kwa zomangamanga.
Zinthu zomwe zimagwiritsidwa ntchito nthawi zambiri zimaphatikizapo: guluu wa matailosi, matope oteteza khoma, ufa wa putty, matope opaka pulasitala, matope odziyimira pawokha, matope osakaniza owuma, ndi zina zotero.
2. Kugwiritsa ntchito mumakampani opaka utoto
Mu makampani opanga utoto ndi utoto, hydroxyethyl methyl cellulose imagwiritsidwa ntchito ngati chokhuthala, chosakaniza, chosungunula, komanso chopangira filimu. Ntchito zake ndi izi:
Kukhuthala ndi kukhazikika: HEMC imatha kukulitsa bwino kukhuthala kwa utoto wa latex, kupewa kutsika kwa utoto, komanso kukonza kukhazikika kwa malo osungira.
Konzani bwino momwe utoto umagwirira ntchito: Konzani bwino momwe utoto umagwirira ntchito popukuta, kuzunguliza kapena kupopera, zomwe zimapangitsa kuti kapangidwe kake kakhale kosalala komanso kuchepetsa kupopera ndi kudontha kwa madzi.
Kusunga madzi ndi kupanga filimu: Kusunga chinyezi bwino pamwamba pa utoto kumathandiza kuti filimuyo ipangidwe bwino komanso kuti filimuyo ikhale yofanana komanso yosalala.
Kukhazikika kwa pH yabwino: HEMC ikhoza kupezeka mosalekeza pa pH yochuluka (3 ~ 11) ndipo ndi yoyenera mitundu yosiyanasiyana ya utoto.
Chifukwa chake, HEMC imagwiritsidwa ntchito mu utoto wopangidwa ndi madzi monga utoto wamkati ndi wakunja wa latex wa pakhoma, utoto wopangidwa ndi madzi wa mafakitale, ndi utoto wamatabwa.
3. Kugwiritsa ntchito mu mankhwala a tsiku ndi tsiku
Hydroxyethyl methylcellulose imagwiritsidwa ntchito kwambiri pazinthu za tsiku ndi tsiku monga shampu, shawa gel, mankhwala otsukira mano, ndi zinthu zosamalira khungu. Ntchito zake zazikulu ndi izi:
Chokhuthala: Kuonjezera kukhuthala kwa zinthu zamadzimadzi ndikuwongolera momwe zinthuzo zimagwirira ntchito.
Kusakaniza ndi kusungunula: Kukhazikitsa dongosolo la emulsion, kuletsa kulekanitsa gawo la mafuta ndi gawo la madzi, ndikupangitsa kuti phala likhale lokhazikika komanso lofanana.
Mphamvu yonyowetsa: Imakhala ndi mphamvu yabwino yosunga madzi, imaletsa madzi kutuluka pakhungu kapena tsitsi, ndipo imawonjezera mafuta.
Kufatsa kwabwino: HEMC ndi cellulose yosakhala ya ionic yomwe siikwiyitsa khungu ndipo ndi yoyenera kugwiritsidwa ntchito pakhungu ndi zinthu zofewa za ana.
4. Kugwiritsa ntchito m'makampani opanga mankhwala ndi chakudya
Ngakhale kuti ntchito zazikulu za HEMC zimayang'ana kwambiri m'mafakitale, HEMC ingagwiritsidwenso ntchito m'mafakitale opanga mankhwala ndi chakudya motsatira malangizo ena.
Zinthu zothandizira mankhwala: HEMC imagwiritsidwa ntchito ngati chomangira, chopangira filimu komanso chotulutsira mankhwala nthawi zonse kuti azitha kulamulira kuchuluka kwa mankhwala omwe amatulutsidwa.
Zowonjezera pazakudya: M'maiko/madera ena, HEMC imaloledwa kugwiritsidwa ntchito ngati chokhuthala chakudya, chosakaniza ndi chokhazikika, monga muzakudya zozizira, maswiti, zokometsera, ndi zina zotero.
Zipangizo zophikira zotulutsa mankhwala nthawi zonse: HEMC imagwiritsidwa ntchito pokonzekera mankhwala otulutsa mankhwala nthawi zonse, ndipo mawonekedwe ake opanga filimu amayang'anira nthawi yotulutsa mankhwala ndi kuchuluka kwa mankhwala m'mimba.
5. Kugwiritsa ntchito m'mafakitale ena
Kuboola mafuta: HEMC imagwiritsidwa ntchito ngati chochepetsera kusefa komanso chokhuthala mumadzi oboola kuti ipangitse kuti madzi oboola akhale olimba komanso kuchepetsa kutayika kwa madzi.
Makampani opanga mapepala: HEMC ingagwiritsidwe ntchito pokonza pamwamba pa pepala kuti ikule bwino, ikhale yolimba komanso yolimba.
Makampani opanga nsalu: Amagwiritsidwa ntchito ngati matope osindikizira ndi kupaka utoto kuti nsalu zikhale ndi kukula koyenera komanso mphamvu zochapira.
Makampani opanga zinthu zadothi: Panthawi yopanga zinthu zadothi, HEMC imalimbitsa mphamvu ya thupi lobiriwira ndipo imawonjezera kufanana kwa glazing.
Hydroxyethyl methylcellulosendi ether ya cellulose yogwira ntchito zambiri yokhala ndi magwiridwe antchito abwino kwambiri komanso yogwiritsidwa ntchito kwambiri. Kukhuthala kwake, kusunga madzi, kupanga filimu, emulsifying ndi zinthu zina zimapangitsa kuti ikhale yofunika kwambiri m'mafakitale ambiri monga zomangamanga, zokutira, mankhwala a tsiku ndi tsiku, mankhwala, ndi chakudya. Ndi kupita patsogolo kwa chitetezo cha chilengedwe chobiriwira komanso malingaliro okhazikika, HEMC, monga chowonjezera choteteza chilengedwe chochokera ku ulusi wachilengedwe, ikuyembekezeka kupitiliza kukulitsa kufunikira kwake pamsika ndi madera ogwiritsira ntchito.
