Kodi pali kusiyana kotani pakati pa cellulose ndi hpmc?

Cellulose ndi hydroxypropyll methylcellulose (hpmc) ndi mankhwala ofunikira omwe ali ndi mapulogalamu osiyanasiyana, makamaka m'mafakitale monga mankhwala monga mafakitale, chakudya, zomangamanga. Ngakhale ali ndi zofanana, amakhalanso ndi kusiyana kosiyana malinga ndi kapangidwe kake, amagwiritsa ntchito, ndi njira zopangira.

Kapangidwe ka 1.Chemical:

Cellulose:
Cellulose ndi polysaride yopangidwa ndi mamolekyu atali a glucose omwe amalumikizidwa pamodzi ndi β-1,4-glycosiidic. Ndi gawo lalikulu la makhoma a cell, ndikuthandizira kuthandizidwa ndi kuthamanga kubzala ziwalo. Cellulose mamolekyulu amapangika microfibrils kudzera kuphatika hydrogen, kumathandizira kulimba mtima komanso kosasunthika kwa cellulose m'madzi ndi okhazikika.

Hpmc:
Hydroxypylm methylcellulose (hpmc) ndi polymer polder yochokera ku cellulose pogwiritsa ntchito mankhwala. Imapangidwa ndi kuchiritsa cellulose ndi Propeylene oxide ndi methyl chloride kuti ayambitse hydroxypyll ndi metholose magulu oyambira pa celluulose. Mulingo wa zolowetsa (DS) mwa maguluwa amatha kukhala osiyanasiyana, kukhudza katundu wa HPMC monga kupulumukira, mafakisoni, ndi mikangano.

2.Palate:

Cellulose:
Kutukula: cellulose yoyera imatha insuluble m'madzi ndi organic soying chifukwa cha kulumikizana kwake kwa hydrogen ndi kapangidwe ka crystarlline.
Biodegradiity: Cellulose ndi biodegradgle, ndikupangitsa kuti chikhale chochezeka komanso choyenera ma eco-ochezeka.
Mphamvu yamakina: ulusi wosewerera amakhala ndi mphamvu zapamwamba kwambiri, zomwe zimathandizira kugwiritsa ntchito m'mapepala, zolembedwa, ndi zida zophatikizika.
Kuperewera kwa Chikunja: Cellulose ndi njira yamankhwala ndipo sizimachita mosavuta ndi zinthu zina zomwe zili m'malo mwabwino.

Hpmc:
Kusungunuka: HPMC imawonetsa kusungunuka m'madzi, ndikupanga njira zowonekera komanso zowoneka bwino. Kusungunuka kumatengera zinthu monga kuchuluka kwa kulowetsa, kunenepa kwambiri, ndi kutentha.
Mapangidwe a filimu: hpmc amatha kupanga mafilimu osinthika komanso owoneka bwino atayanika, kupangitsa kuti ikhale yothandiza mu zokutira zamankhwala, ma CD ya chakudya, ndi ntchito zina.
Masinthidwe a HPMC ali ndi mafayilo osinthika malinga ndi zinthu monga chidwi, kutentha, ndi kuchuluka kwa zolowa m'malo. Katunduyu ndi wofunikira pakuwongolera machitidwe azomera.
Bioditheion: HPMC ili ndi katundu wa biodesive, kulola kutsatira zachilengedwe mawonekedwe monga mucosal membranes. Izi zikugwiritsidwa ntchito pakupanga mankhwala osokoneza bongo a mankhwala osokoneza bongo.

3.Pestictions:

Cellulose:
Pepala ndi makatoni: ulusi wa cellulose ndiwofunikira kwambiri papepala ndi makatoni opangira mapepala chifukwa cha kuchuluka kwake ndi mphamvu zawo.
Zolemba: thonje, fini ya chilengedwe lomwe limapangidwa makamaka la cellulose, limagwiritsidwa ntchito kwambiri pamakampani opanga zovala, kukweza, ndi zinthu zina zopangidwa ndi nsalu.
Zipangizo zomangira: Zojambula zopangidwa ndi cellulose monga nkhuni, plywood, ndi tinthu tambiri ndizofala pomanga mawonekedwe ndi zokongoletsera.
Zowonjezera Zowonjezera

Hpmc:
Mapangidwe a mankhwala: HPMC imagwiritsidwa ntchito kwambiri mu mankhwala ogulitsa, kanema wakale, wosuta-wosuta, mapiritsi, mafinya, mafinya a ophthahalmic, ndi mawonekedwe apamwamba.
Zipangizo zomangira: HPMC imawonjezeredwa ndi matope opangidwa ndi sile, zomata za matayala, ndipo zodzikongoletsera zodzipangitsa kuti zithandizire kugwirira ntchito, kusungidwa kwamadzi, ndi malo atsanzike.
Makampani ogulitsa zakudya: HPMC imagwiritsidwa ntchito ngati thickener, emulsifier, okhazikika, ndi ziphuphu za zakudya zosiyanasiyana, kuphatikizapo msuzi, zakudya, nyama.
Zogulitsa Zaumwini: HPMC imapezeka mu zodzoladzola, zimbudzi, ndi zinthu zaumwini monga zotupa, zonona, ma shalsifer, ndi filimu yomwe kale.

4.Munthu:

Cellulose:
Cellulose makamaka imapezeka kuchokera ku probnings kudzera njira monga makina ojambula (mwachitsanzo, kupera kachisi wamakina), kusefukira kwamankhwala (mwachitsanzo, kupanga bacteriya (mwachitsanzo, kupanga ma cellueteriya (mwachitsanzo, kupanga ma cellueteriya). Cellulose yochotsedwa imayeretsedwa ndikukonzekera kupeza mitundu yosiyanasiyana ya magwiridwe osiyanasiyana.

Hpmc:
Kupanga kwa HPMC kumaphatikizapo masitepe angapo, kuyambira ndi kuchotsera kwa cellulose ku magwero a mbewu monga mtengo wamtengo wapatali kapena mabatani a thonje. Cellulose imathandizidwa ndi alkali kuti ichotse zodetsa zisanachitike ndi Propylene Oxide ndi methyl chloride kuti ayambitse ma hydroxypyl ndi memoxy. Zotsatira za HPMC zimayeretsedwa, zouma, komanso zamitundu yofunikira kuti igwiritse ntchito malonda.

Cellulose ndi HPMC ndi zonse zofunikira ndi mapulogalamu osiyanasiyana pamakampani osiyanasiyana. Cellulose ndi polysacdide wachilengedwe wopezeka khoma la cell, HPMC ndi chosinthika cha cellulose ndi sobenced solubility ndi magwiridwe antchito. Kusiyana kwawo kopangidwa ndi mankhwala, katundu, kugwiritsa ntchito, njira zopangira zimawapangitsa kukhala oyenera kugwiritsidwa ntchito mosiyanasiyana, kuyambira pakupanga kwachikhalidwe komanso kapangidwe kake kopanga mapangidwe ndi zinthu zomangamanga. Kuzindikira zokhumudwitsa izi ndikofunikira kuti mumvetsetse zinthu zapadera za cellulose ndi hpmc pakupanga zinthu zatsopano.
