1. Kodi hydroxypropyl methylcellulose ndi chiyani?
Hydroxypropyl methylcellulose (HPMC)ndi ether yopanda poizoni komanso yopanda vuto ya cellulose, yomwe imagwiritsidwa ntchito kwambiri popanga zinthu zomangira, chakudya, mankhwala, zodzoladzola ndi zina. Ili ndi ntchito zokhuthala, kusunga madzi, kupanga filimu, kugwirizana, mafuta ndi kuyimitsa, ndipo imatha kusungunuka m'madzi kuti ipange yankho lowonekera kapena lowala.
2. Kugwiritsa ntchito ndi kugwiritsa ntchito HPMC kawirikawiri
Munda womanga
HPMC imagwiritsidwa ntchito kwambiri popanga zipangizo zomangira monga simenti, ufa wa putty, guluu wa matailosi, ndi zina zotero.
Ntchito: Kupititsa patsogolo ntchito yomanga, kukonza kusunga madzi, kuwonjezera nthawi yotsegulira, ndikuwongolera magwiridwe antchito omangira.
Njira yogwiritsira ntchito:
Onjezani mwachindunji ku matope osakaniza ouma, kuchuluka komwe kumalimbikitsidwa ndi 0.1% ~ 0.5% ya kulemera kwa simenti kapena substrate;
Mukasakaniza bwino, onjezerani madzi ndikusakaniza mu slurry.
Makampani ogulitsa zakudya
HPMC ingagwiritsidwe ntchito ngati chokhuthala, chokhazikika komanso chosakaniza, ndipo imapezeka kwambiri muzakudya monga ayisikilimu, jeli, buledi, ndi zina zotero.
Ntchito: Kukonza kukoma, kukhazikika kwa dongosolo, ndikuletsa kugawikana.
Kagwiritsidwe:
Sungunulani m'madzi ozizira, mlingo woyenera umasinthidwa pakati pa 0.2% ndi 2% malinga ndi mtundu wa chakudya;
Kutentha kapena kusakaniza ndi makina kungathandize kusungunula zinthu mwachangu.
Makampani opanga mankhwala
HPMC nthawi zambiri imagwiritsidwa ntchito popanga mapiritsi opaka mankhwala, mapiritsi otulutsa mankhwala okhazikika kapena chipolopolo cha capsule:
Ntchito: kupanga filimu, kuchedwa kutulutsa mankhwala, komanso kuteteza ntchito ya mankhwala.
Kagwiritsidwe:
Konzani mu yankho lokhala ndi kuchuluka kwa 1% mpaka 5%;
Thirani mofanana pamwamba pa piritsi kuti mupange filimu yopyapyala.
Zodzoladzola
HPMCimagwiritsidwa ntchito ngati chokhuthala, chokhazikika cha emulsion kapena chopangira filimu, chomwe chimagwiritsidwa ntchito kwambiri mu masks a nkhope, lotions, ndi zina zotero.
Ntchito: Sinthani kapangidwe kake ndikuwonjezera kumveka kwa chinthucho.
Kagwiritsidwe:
Onjezani ku cosmetic matrix molingana ndi momwe mukufunira ndipo sakanizani mofanana;
Mlingo nthawi zambiri umakhala 0.1% mpaka 1%, wosinthidwa malinga ndi zomwe mankhwalawo akufuna.
3. Njira yosungunula HPMC
Kusungunuka kwa HPMC kumakhudzidwa kwambiri ndi kutentha kwa madzi:
N'zosavuta kusungunuka m'madzi ozizira ndipo zimatha kupanga yankho lofanana;
Sisungunuka m'madzi otentha, koma imatha kufalikira ndikupanga colloid ikazizira.
Njira zenizeni zosungunula:
Thirani HPMC pang'onopang'ono m'madzi, pewani kuthira mwachindunji kuti musaphike;
Gwiritsani ntchito chosakaniza kuti musakanize mofanana;
Sinthani kuchuluka kwa yankho ngati pakufunika.
4. Malangizo ogwiritsira ntchito HPMC
Kuwongolera Mlingo: Muzochitika zosiyanasiyana zogwiritsira ntchito, mlingo umakhudza mwachindunji magwiridwe antchito ndipo uyenera kuyesedwa malinga ndi zosowa.
Malo Osungira: Iyenera kusungidwa pamalo ozizira, ouma, komanso opumira mpweya kuti ipewe chinyezi ndi kutentha kwambiri.
Kuteteza chilengedwe: HPMC imatha kuwonongeka ndipo siipitsa chilengedwe, koma ikufunikabe kugwiritsidwa ntchito mwanjira yokhazikika kuti isatayike.
Kuyesa kuyanjana: Mukawonjezera ku machitidwe ovuta (monga zodzoladzola kapena mankhwala), kuyanjana ndi zosakaniza zina kuyenera kuyesedwa.
5. Ubwino wa HPMC
Sizowopsa, zoteteza chilengedwe, komanso zotetezeka kwambiri;
Kusinthasintha, kusinthasintha malinga ndi zofunikira zosiyanasiyana zogwiritsira ntchito;
Kukhazikika bwino, kumatha kusunga magwiridwe antchito kwa nthawi yayitali.
6. Mavuto ndi mayankho ofala
Vuto la kusakanikirana kwa zinthu: Samalani ndi kuwonjezera zinthu mosakaniza mukamazigwiritsa ntchito ndipo sakanizani zonse nthawi imodzi.
Kusungunuka kwa nthawi yayitali: Kutsuka ndi madzi otentha kapena kusakaniza ndi makina kungagwiritsidwe ntchito kuti kusungunuke mwachangu.
Kuwonongeka kwa magwiridwe antchito: Samalani malo osungiramo zinthu kuti mupewe chinyezi ndi kutentha.
Pogwiritsa ntchito HPMC mwasayansi komanso mwanzeru, makhalidwe ake ambiri angagwiritsidwe ntchito mokwanira kuti apereke mayankho apamwamba kwambiri m'mafakitale osiyanasiyana.
