1. Hydroxypropyll methylcelulose?
Hydroxypropyl methylcellulose (hpmc)ndi ma exul osavomerezeka ndi osokoneza bongo osavulaza, zomwe zimagwiritsidwa ntchito kwambiri pazomangira, chakudya, mankhwala, zodzoladzola komanso minda ina. Ili ndi ntchito za kukula, kusungunuka kwamadzi, mapangidwe apakanema, ogwiritsira ntchito, mafuta ndi kuyimitsidwa m'madzi kuti apange mawonekedwe a viscous.
2. Kugwiritsa ntchito kofala ndi kugwiritsa ntchito HPMC
Gawo Lomanga
HPMC imagwiritsidwa ntchito pomanga zida zomangira monga matope a simenti, putty ufa, zomata za tile, ndi zina.:
Ntchito: Kulimbikitsa magwiridwe antchito, kusintha kusungidwa kwamadzi, kotseguka nthawi, ndikusintha magwiridwe antchito.
Njira Yogwiritsira Ntchito:
Onjezani mwachindunji matope osakanikirana, ndalama zolimbikitsidwa ndi 0.1% ~ 0,5% ya unyinji wa simenti kapena gawo lalikulu;
Atasuntha kwathunthu, onjezani madzi ndikuyambitsa kusalala.
Makampani Ogulitsa Chakudya
HPMC ikhoza kugwiritsidwa ntchito ngati thickener, ribilifar ndi emulsifier, ndipo nthawi zambiri amapezeka muzakudya monga ayisikilimu, odzola, mkate.:
Ntchito: Sinthani kukoma, khazikitsani dongosolo, ndikuletsa stratization.
Kugwiritsa Ntchito:
Sungunulani m'madzi ozizira, mlingo woyenera umasinthidwa pakati pa 0,2% ndi 2% malinga ndi mtundu wa chakudya;
Kutentha kapena kupanga makina kumatha kuthamangitsa kufalikira.
Makampani opanga mankhwala
Hpmc nthawi zambiri amagwiritsidwa ntchito mu piritsi la mankhwala opanga mankhwala, piritsi lokhazikika kukhazikika kapena kapisozi:
Ntchito: Mapangidwe a filimu, kumasulidwa mankhwala osokoneza bongo, ndi kuteteza mankhwala.
Kugwiritsa Ntchito:
Konzekerani yankho ndi kuchuluka kwa 1% mpaka 5%;
Utsi wotsika pa piritsi kuti apange filimu yopyapyala.
Choongoletsera
Hpmcimagwiritsidwa ntchito ngati thickener, emulsion Stateger kapena othandizira mafilimu, omwe nthawi zambiri amagwiritsidwa ntchito m'masamba a nkhope, zotupa, zotupa.:
Ntchito: Sinthani mawonekedwe ndi kukulitsa momwe akumvera.
Kugwiritsa Ntchito:
Onjezani ku malo odzikongoletsa molingana mogwirizana;
Mlingo nthawi zambiri umakhala 0,1% mpaka 1%, osinthidwa malinga ndi zofunikira zamalonda.
3. Njira ya HPMC
Kusungunuka kwa HPMC kumakhudzidwa kwambiri ndi kutentha kwamadzi:
Ndikosavuta kusungunuka m'madzi ozizira ndipo amatha kupanga njira yothetsera yunifolomu;
Ndizopanda malire m'madzi otentha, koma imatha kubalalitsidwa ndikupanga cololoid pambuyo pozizira.
Njira Zosasinthika:
Kuwaza HPMC pang'onopang'ono m'madzi, pewani kuthira mwachindunji kuti mupewe kugwira;
Gwiritsani ntchito chosokoneza kusakanikirana;
Sinthani yankho lomwe likufunika pakufunika.
4. Kukwaniritsa kugwiritsa ntchito HPMC
Kuwongolera Mlingo: Mu zochitika zosiyanasiyana zofunsira, Mlingo umakhudzanso magwiridwewo ndipo akufunika kuyesedwa malinga ndi zosowa.
Iyenera kusungidwa pamalo ozizira, youma, yopanda mpweya kuti mupewe kutentha komanso kutentha kwambiri.
Chitetezo cha chilengedwe: hpmc ndi biodegged ndipo sichimaipitsa chilengedwe, koma chikufunikabe kugwiritsidwa ntchito m'njira yoyenera kupewa kuwononga.
Kuyesa kwa Kugwirizana: Mukawonjezeredwa pamakina ovuta (monga zodzoladzola kapena mankhwala), kuyerekezera ndi zosakaniza zina ziyenera kuyesedwa.
5. Ubwino wa HPMC
Osadandaula, ochezeka, otetezeka kwambiri;
Kusiyanitsa, kusinthanso njira zosiyanasiyana zogwiritsira ntchito;
Kukhazikika kwabwino, kumatha kusunga magwiridwe antchito kwa nthawi yayitali.
6. Mavuto Akale ndi Mayankho
Vuto lokhala ndi vuto loti: Yang'anirani omwazika kuwonjezera kuwonjezera ndikusuntha nthawi yomweyo.
Nthawi yayitali yosungunuka: Kupanga madzi otentha kapena kupanga makina kungagwiritsidwe ntchito pofuna kuthamangitsa chisinthiko.
Kuwonongeka kwa magwiridwe antchito: Yang'anirani kumalo osungira kuti musanyoze ndi kutentha.
Pogwiritsa ntchito HPMC mwasayansi komanso mwamwano, mikhalidwe yake yosiyanasiyana imatha kugwiritsidwa ntchito mokwanira kupereka njira zapamwamba kwambiri.
