Ndi iti yomwe ili bwino, CMC kapena HPMC?

CMC (sodium carboxymethyl cellulose) ndi HPMC (hydroxypropyl methyl cellulose) ndi zotumphukira ziwiri zomwe zimagwiritsidwa ntchito kwambiri m'mafakitale osiyanasiyana. Kuti ndi iti yomwe ili yabwinoko, zimatengera momwe mungagwiritsire ntchito komanso zosowa zake.

1. Mankhwala katundu
CMC ndi anionic madzi sungunuka polima pawiri anapezedwa pochiza masoka mapadi ndi sodium chloroacetate pansi zamchere. Magulu a carboxymethyl amalowetsedwa mu unyolo wa mamolekyu ake, omwe amapangitsa kuti azikhala ndi madzi abwino osungunuka komanso kukhuthala.

HPMC ndi non-ionic cellulose ether yomwe imapezeka pochita mapadi ndi methyl chloride ndi propylene oxide. Magulu a methoxy ndi hydroxypropoxy mu mawonekedwe a mamolekyu a HPMC amapatsa kukhuthala bwino, kukhazikika komanso kusunga madzi, komanso katundu wabwino wa gel osakaniza.

2. Minda yofunsira
Makampani chakudya: CMC nthawi zambiri ntchito chakudya monga thickener, stabilizer, suspending wothandizila ndi emulsifier, etc., ndipo ambiri opezeka yoghurt, ayisikilimu, odzola, zakumwa ndi zophikidwa mankhwala. Itha kukulitsa kapangidwe ka chakudya ndikukulitsa moyo wa alumali. Ngakhale HPMC imagwiritsidwanso ntchito m'makampani azakudya, imagwiritsidwa ntchito ngati chowonjezera pazakudya, makamaka pazinthu zina zopanda gluten.

Makampani Azamankhwala: HPMC imagwiritsidwa ntchito kwambiri m'makampani opanga mankhwala, makamaka pakupaka mapiritsi, mankhwala otulutsa oyendetsedwa komanso kupanga makapisozi. Makhalidwe ake osakhala a ionic ndi biocompatibility yabwino amamupatsa mwayi wapadera pamakina operekera mankhwala. CMC imagwiritsidwanso ntchito m'makampani opanga mankhwala, koma monga chowonjezera komanso zomatira pamankhwala.

Makampani omanga ndi zokutira: HPMC imagwiritsidwa ntchito kwambiri muzomangamanga, makamaka mumatope owuma, gypsum, ndi putty powder, chifukwa cha kusungirako bwino kwa madzi, kukhuthala komanso anti-slip properties. CMC ilinso ndi ntchito zina pamakampani opanga zokutira, koma imagwiritsidwa ntchito kwambiri ngati zokutira zotengera madzi.

Zodzoladzola ndi chisamaliro cha munthu: HPMC nthawi zambiri ntchito zodzoladzola, makamaka lotions, creams, shampu ndi otsukira mano, monga thickener, emulsion stabilizer ndi moisturizer. CMC imagwiritsidwanso ntchito pazinthu zofananira, koma zotsatira zake zonyowa sizofanana ndi HPMC.

3. Makhalidwe amachitidwe
Kusungunuka kwamadzi: CMC imatha kusungunuka m'madzi ozizira komanso otentha, pomwe HPMC imasungunuka mosavuta m'madzi ozizira, koma osasungunuka m'madzi otentha ndipo imakhala ndi gelation yotentha. Chifukwa chake, HPMC ndiyabwino kwambiri pazinthu zomwe zimafunikira matenthedwe a gelation muzinthu zina, monga mapiritsi otulutsidwa muzamankhwala.

Kuwongolera mamasukidwe akayendedwe: CMC ili ndi kukhuthala kocheperako ndipo ndiyosavuta kuwongolera, pomwe HPMC ili ndi kukhuthala kwakukulu komanso kusinthika. HPMC ikhoza kupereka mamasukidwe apamwamba kwambiri ndikukhalabe okhazikika pa kutentha kosiyana, zomwe zimapangitsa kuti zikhale zopindulitsa kwambiri pazogwiritsira ntchito zomwe zimafuna kuwongolera kusinthasintha kwachangu.

Kukhazikika: HPMC ili ndi kukhazikika kwamankhwala kuposa CMC. Imawonetsa kukhazikika kwabwino m'malo okhala acidic kapena amchere, pomwe CMC imatha kutsitsa ma acid amphamvu kapena maziko amphamvu.

4. Mtengo ndi mtengo
Nthawi zambiri, CMC ndi yotsika mtengo komanso yoyenera ntchito zamakampani akuluakulu, pomwe HPMC ndiyokwera mtengo chifukwa chazovuta zake zopanga komanso kukwera mtengo. CMC ikhoza kukhala yokongola kwambiri pakafunika kuchuluka kwakukulu komanso mtengo wake ndi wovuta. Komabe, m'madera ena omwe ali ndi zofunikira zogwirira ntchito, monga mankhwala ndi zodzoladzola zapamwamba, HPMC imagwiritsidwabe ntchito kwambiri chifukwa cha ubwino wake wapadera ngakhale kuti ili ndi mtengo wapamwamba.

5. Kuteteza chilengedwe ndi chitetezo
Onse CMC ndi HPMC ali ndi biodegradability wabwino ndi kuteteza chilengedwe, ndipo alibe mphamvu pa chilengedwe pa ntchito. Onse amaonedwa otetezeka chakudya ndi zina mankhwala, ndipo akhoza bwinobwino ntchito zosiyanasiyana mankhwala pambuyo kuyang'aniridwa mosamala ndi chiphaso.

CMC ndi HPMC ali ndi ubwino ndi kuipa kwawo, ndipo n'zosatheka kungonena kuti ndi yabwino. Pazogwiritsa ntchito zomwe zimafuna zotsika mtengo, zopanga zazikulu, monga makampani azakudya wamba komanso zosowa zosavuta zakukula, CMC ndi chisankho chotsika mtengo. M'madera omwe ali ndi zofunikira zogwirira ntchito, monga machitidwe otulutsidwa ndi mankhwala, zipangizo zomangira zapamwamba ndi zodzoladzola zapamwamba, HPMC ikhoza kukhala yoyenera chifukwa cha ntchito yake yabwino. Chifukwa chake, kusankha komwe kumachokera ku cellulose kumatengera zofunikira zomwe zimagwiritsidwa ntchito, zofunikira zogwirira ntchito komanso malingaliro amtengo.
