Kodi pali kusiyana kotani pakati pa hydroxypypyl methylcellulose ndi chigololo celluuse

Kodi pali kusiyana kotani pakati pa hydroxypypyl methylcellulose ndi realuse yophatikizika?

Woyerahydroxypropyl methylcellulose (hpmc)Ndipo celluose yophatikizika imakhala ndi kusiyana kwakukulu pamitengo, magwiridwe antchito ndi madera ogwiritsira ntchito.

1. Kapangidwe ka mankhwala ndi kapangidwe kake
Ma hydroxypypyl a methylcellulose (hpmc): hydroxypropyll methylcellulose ndi malo osungunuka madzi osungunuka omwe amapangidwa ndikusintha cellulose mwachilengedwe. Chinthu chake chachikulu ndichakuti magulu ena a hydroxyl (oh) amasinthidwa ndi methyl (-Och3) ndi hydroxypropyl (-Ch3hniohpropyl (-Ch3hnihpropyl (-Ch3hnihpropyl (-Ch3hniohpropyl (-Ch3hniohpropyl (-Ch3hnioh) pa ma atomu a okosijeni a cellulose. Makamaka, mawu oyamba a methyl ndi hydroxypyl amasintha kusungunuka, mamasukidwe ndi zina mwa cellulose, zomwe zimapangitsa kuti zisungunuke m'madzi ndipo nthawi zambiri zimagwiritsidwa ntchito ngati chomata.

Celluuse yophatikizika yophatikizika: celluuse yolumikizidwa nthawi zambiri imapangidwa ndi kusakaniza hpmc yokhala ndi mitundu ina ya cellulose kapena zowonjezera zamankhwala m'njira inayake. Zowonjezera izi zitha kuphatikizapo ma celloul otsika mtengo, ngakhale ma dinelloose ogwiritsa ntchito kapena osavomerezeka, omwe atha kukhala ndi zofooka zina, makamaka mu solobility, kukhazikika komanso kukhazikika.

2. Solubility ndi kusungunuka madzi
HPMC yoyera: yoyera ya HPMC imakhala ndi madzi abwino kwambiri ndipo amatha kupanga yankho lomveka m'madzi ozizira. Kusungunuka ndi mawonekedwe a HPMC kumasiyanasiyana malinga ndi kuchuluka kwa methylation ndi hydroxypropropropropropropropy. Mwambiri, oyera hpmc ali ndi solubite komanso kukhazikika, makamaka m'madzi osungunuka ndi bata.

Celluuse yophatikizika yophatikizika: celluuse yokhazikika imatha kukhala yosauka chifukwa chophatikizira zosakaniza ndi zowonjezera zotsika kwambiri, ndipo mwina sizingasungunuke kwathunthu m'madzi kapena kupanga madzi otumphuka. Kusintha kumeneku kumangokhudza momwe zimagwiritsira ntchito m'mapulogalamu osiyanasiyana, koma kungabweretsenso zinthu zopanda thupi, zomwe zimapangitsa kuti zikhale zowononga.

3.. Magwiridwe antchito ndi kukhazikika
HPMC yoyera: yoyera hpmc imakhala ndi bata kwambiri komanso kusinthasintha kwabwino kusintha zinthu zachilengedwe monga pH, kukhazikika mchere, komanso kutentha. Kukhazikika kwake kumapangitsa HPMC kugwiritsidwa ntchito mu mankhwala opangira mankhwala, chakudya, zodzoladzola ndi mafakitale ena monga womata, zomata, wothandizidwa, wosuta, ndi omasulidwa, etc.

Celluuse yophatikizika yophatikizika: cellulose yokhazikika imakhazikika bwino, makamaka pansi pa kutentha kosiyanasiyana, ph ndi mphamvu ya ph ndi ionic imasintha, imatha kuwonongeka kapena kuwonongeka. Kukhazikika kumeneku kumatha kuyambitsa mavuto amtundu wazophatikizira ndikukhudza kudalirika kwa chinthu chomaliza. Mwachitsanzo.

4..
HPMC yoyera: yoyera ya HPMC nthawi zambiri imakhala ndi kusintha kwa ma visadi, kumatha kusintha mafayilo a njira yosiyanasiyana, ndipo imagwiritsidwa ntchito kwambiri m'mafakitale omwe akufunika kusintha rimology. Ilinso ndi mapangidwe abwino, amatha kupanga filimu yolimba, ndipo ili ndi madzi olimba ndi kukana kusagwirizana.

Ma celluuse ophatikizidwa ndi cellulose yolumikizidwa: celluose yophatikizidwa ndi celluose yophatikizika ndiyosakhazikika muthupi. Chifukwa cha kuwonjezera kwa zosakaniza zotsika, cellulose yolakwika imatha kuchita bwino mu mafilimu, chinsinsi, etc., ndipo mwinanso kulephera kukwaniritsa zotsatira zake. Kuphatikiza kwa cellulose yotsekera kumatha kubweretsa kutchire yomaliza yamakina, akukhudza moyo wake ndi ntchito zake.

5. Ntchito Zogwiritsa Ntchito
HPMC yoyera: Gawo la ntchito ya HPMC yoyera ndi yopingasa kwambiri, kuphimba mafakitale angapo monga mankhwala monga mankhwala opangira mankhwala, chakudya, zodzoladzola komanso zomangamanga. M'makampani opanga mankhwala, nthawi zambiri amagwiritsidwa ntchito ngati wogwirizira mankhwala omasulidwa, omwe amapatsa zipolopolo ndi mapiritsi a mapiritsi ndi mapiritsi; Mu chakudya, hpmc imagwiritsidwa ntchito ngati thicker, emulsifier ndi kukhazikika; M'makampani omanga, HPMC imagwiritsidwa ntchito ngati thickiner ndi wothandizila madzi osungira madzi; Mu zodzoladzola, imagwiritsidwa ntchito muzogulitsa monga zowonera, ma gelos ndi shampoos.

Ma cellue ophatikizidwa ndi ma celluose ophatikizidwa: Ntchito zogwiritsidwa ntchito mitundu ya celluose yophatikizika ndi yochepa chifukwa cha zovuta zake. Nthawi zambiri imagwiritsidwa ntchito m'malo omwe ali ndi zofunikira zochepa, monga zokutira zochepa, glues kapena zida zomangira. Mtengo wotsika wa cellulose imapangitsa kuti ikhale yogwiritsa ntchito pogwiritsa ntchito njira zina zazifupi, koma chifukwa cha kusakhazikika kwake, nthawi yayitali yogwiritsa ntchito zotsatira zake sizabwino.

6. Mtengo ndi chuma
HPMC yoyera: mtengo wopanga wa HPMC yoyera imakhala yokwera kwambiri, makamaka chifukwa cha zida zapamwamba komanso zopangira. Komabe, chifukwa cha ntchito yake yayikulu komanso kugwiritsa ntchito kwazonse, kugwiritsa ntchito HPMC kumatha kubweretsa mtengo wowonjezereka, kotero ali ndi nthawi yayikulu pamsika m'mafakitale apamwamba kwambiri.

Celluuse yophatikizika yophatikizika: celluuse yolumikizidwa kawirikawiri imachepetsa mtengo powonjezera ma cellulose kapena mankhwala, motero mtengo wopanga ndi wotsika. Izi zimapangitsa ma cellulose modekha kukhala ndi msika wina m'minda ina yokhala ndi zofunikira zina, koma pakapita nthawi, chifukwa cha zovuta zomwe zingayambike chifukwa cha mtundu wake wotsika, zitha kuchititsa mbiri yabwino yamalonda ndi msika.

7. Chitetezo cha chilengedwe

HPMC yoyera: monga celluese yosinthika yochokera ku chilengedwe chachilengedwe, ali ndi maubwino ena okhala ndi chilengedwe. Ndi biodegragged ndipo imakhala ndi kuipitsa pang'ono pachilengedwe, komwe kumakwaniritsa zofunikira zamakono zobiriwira zamakono.

Ma cellue ophatikizidwa ndi ma celluose ophatikizidwa: celluuse yolumikizidwa ndi celluose yambiri imatha kukhala ndi zovuta zina chifukwa cha chilengedwe chifukwa zimatha kukhala ndi zigawo zosadziwika ndi mankhwala. Makamaka panthawi yokonza, cellulose yolakwika imawonongeka kwambiri ndipo imayambitsa kuipitsidwa m'nthaka ndi madzi.

Pali zosiyana kwambiri pakati pa oyerahydroxypypyl methylcelluloseNdipo celluuse yolumikizidwa munthawi zambiri, makamaka pamankhwala, kusungunuka, kukhazikika, zinthu zathupi ndi madera ogwiritsira ntchito. HPMC yoyera imakhala ndi magwiridwe apamwamba komanso kukhazikika, motero ndikoyenera kwa mafakitale ndi zofunikira zapamwamba; Ngakhale celluose yolumikizidwa ndi celluose yomwe ili ndi maubwino, kusagwira kwake bwino komanso kusakhazikika kumangogwiritsa ntchito pamsika wotsiriza. Kusankha mtundu wa cellulose kugwiritsa ntchito kumafuna kuyesa ubale pakati pa magwiridwe antchito ndi mtengo wotsatira zofunikira zapadera ndi malo ogwiritsira ntchito.
