Chiyambi
Hydroxypylropyl (HPMC) ndi yosiyanasiyana, yopanga polity yochokera ku cellulose. Malo ake apadera amapangitsa kukhala chinthu chofunikira kwambiri m'makampani osiyanasiyana, kuphatikizapo mafakitale, kuphatikiza, ndi kupanga chakudya. Chimodzi mwazinthu zofunika kwambiri za HPMC ili mu zophimba, pomwe imagwira ntchito yoyambilira yolimba.
Kapangidwe ka mankhwala ndi katundu wa hpmc
HPMC ndi ether ether, zomwe zikutanthauza kuti zimachokera ku cellulose yosiyanasiyana kudzera mu kusintha kwamankhwala. Zosintha zoyambirira zimaphatikizapo kuyambitsa kwa hydroxpyl ndi magulu a methyl. Kusinthika kumeneku kwa HPMC yokhala ndi zinthu zingapo zopindulitsa, kuphatikizapo kusungunuka m'madzi ndi organic, luso la makanema, komanso kukhazikika kwa mafuta. Izi ndizofunikira pakugwiritsa ntchito magwiridwe antchito pomwe magwiridwe antchito amatengera kwambiri pazomwe zidagwiritsidwa ntchito.
Kusungunuka ndi mafomu a makanema:
HPMC imasungunuka mosavuta m'madzi ndikupanga njira yomveka bwino. Pouma, imapanga filimu yolimba, yosinthika. Kutha kwa mafilimu kumeneku ndikofunika kwambiri pakukumba monga kumapangitsa kuti pakhale yunifolomu yomwe ingatsatire mwamphamvu kwa magawo osiyanasiyana.
Kuwongolera Visccence:
Makulidwe a ma hpmc mayankho a HPMC akhoza kuphatikizidwa ndikusintha digiri ya polymerization ndi chiwerengero cha hydroxypyl m'magulu a methyl. Katunduyu amalola opanga mapulogalamu kuti apange zokutira ndi kusinthaku komwe kukufunidwa komanso kunenepa, ndikuwonetsetsa zotsatsa zoyenera.
Kukhazikika kwa matenthedwe:
HPMC imawonetsa bwino kwambiri mafuta, omwe ndi ofunikira kuti ayamikiridwa ndi kutentha kosiyanasiyana. Kukhazikika uku kumatsimikizira kuti zomatira za zokutidwa zimasungidwa mosiyanasiyana.
Njira zamankhwala zotsatsa
Kupitikitsa patsogolo kwa chotsatsa ndi hpmc pakugwiritsa ntchito magwiridwe antchito kungachitike pamakina angapo:
Makina ogwiritsira ntchito makina:
HPMC imapanga filimu yopitilira yomwe imatha kulowa mu micro-indetion ya gawo lapansi. Izi zimalola kulowera kwamakina, komwe kumapangitsa kwambiri kutengera kolumikizana ndi gawo lapansi. Kanemayo amachita ngati chophimba chakuthupi, kukonza mphamvu yapakati pa zokutidwa ndi pamwamba.
Kusintha kwamphamvu:
HPMC imatha kusintha mphamvu ya padziko lapansi, ndikupangitsa kuti ikugwirizana ndi nkhani yokutidwa. Kugwirizana uku kumachepetsa zovuta zovuta pakati pa zokutira ndi gawo lapansi, kuthandizira chotsatsa bwino. Magulu a Polar ku HPMC amalumikizana ndi gawo lapansi, limakulitsa chivomerezi ndikufalikira.
Hydrogen Coomring ndi Magetsi Actoction:
Kupezeka kwa magulu a ma hydroxyl ku HPMC kumalola kupangidwa kwa ma hydrogen ndi gawo lapansi. Maungufuwa amapanga magawo owonjezera ophatikizidwa, kulimbikitsa zomatira za zokutira. Kuphatikiza apo, kusanja kwamagetsi pakati pa polymer ndi gawo lapansi kungakulimbikitsenso.
Zotchinga Zotchinga:
Makanema a HPMC amatha kukhala ngati zotchinga, kuteteza gawo loyambitsidwa ndi chinyontho ndi zinthu zina zomwe zingafooketse zotsatsa. Choyimira chotchinga ichi chimatsimikizira kuti kutsatira kumakhalabe kolimba pakapita nthawi, ngakhale pamavuto.
Ntchito ndi makampani opindulitsa
Zovala za mankhwala:
M'makampani opanga mankhwala, HPMC imagwiritsidwa ntchito kwambiri pa piritsi. Polymer sikuti amangowonjezera cholumikizira cholumikizira pa piritsi komanso chimawongolera kutulutsidwa kwa zosankhidwa. Kumasulidwa kumeneku ndikofunikira kuti musunthe bwino mankhwalawa.
Ntchito Zomanga ndi Zojambula:
HPMC imagwiritsidwa ntchito m'magawo osiyanasiyana omanga, kuphatikizapo zojambula ndi zokutira pamakoma ndi kudekha. Kutha kwake kupititsa patsogolo kotsatsa kumatsimikizira kuti utoto umakhala wosasunthika ndipo sunadutse kapena pang'ono pakapita nthawi. Kukhazikika kumeneku ndikofunikira kuti mukhalebe ndi mikhalidwe yachiyero komanso yoteteza.
Makampani Ogulitsa Chakudya:
M'makampani azakudya, HPMC imagwiritsidwa ntchito muzovala zabwino za zipatso ndi ndiwo zamasamba. Zovala izi zimawonjezera moyo wa alumali wa zokololazo popereka chotchinga. Chovala chabwino kwambiri cha HPMC onetsetsani kuti zokutidwazo zimakhalabe, kusungitsa kukonzekera chakudya.
Zodzikongoletsera:
HPMC imagwiritsidwanso ntchito popanga zodzikongoletsera, pomwe zimathandizira kupanga filimu yosalala, yotsatira pakhungu. Kanemayu amapereka chotchinga choteteza ndikusintha moyo wazodzikongoletsera zodzikongoletsera pakhungu.
Ubwino Woposa Olima Ena
HPMC imapereka zabwino zambiri pa ma polima ena omwe amagwiritsidwa ntchito povala:
Osadandaula:
HPMC siyopanda poizoni ndi bioom, ndikupangitsa kuti ikhale yoyenera kugwiritsa ntchito chakudya ndi mankhwala omwe chitetezo chimakhala chofunikira.
Kuchezeka Kwachilengedwe:
Kuchokera ku cellulose, hpmc ndi biodegrad komanso kopepuka. Khalidwe ili limakhala lofunikira kwambiri m'makampani ofuna kuchepetsa mawonekedwe a injini.
Kusiyanitsa:
Kutha kusintha mafayilo ndi mawonekedwe a filimu a HPMC imalola kugwiritsa ntchito ntchito zosiyanasiyana, kuchokera kumafilimu oonda kuvutenti. Kuchita kusintha kumeneku kumapangitsa kuti opanga alamulilo azisankha.
HPMC imachita mbali yovuta yotsanzira zotsatsa m'mapulogalamu osiyanasiyana akulu chifukwa cha kapangidwe kake ka mankhwala ndi katundu. Kutha kwake kwa makanema, kukhazikika kwa mafakitale, komanso kuthekera kopanga zomangira zolimba ndi miyala kumapangitsa kukhala chinthu chofunikira kwambiri m'mafakitale omanga. Njira zomwe HPMC imathandizira kulowera pamakina, kusintha kwamphamvu, mphamvu ya hydrogen, ndi zotchinga - onetsetsani kuti zokutira zimakhala zolimba komanso zothandiza. Pamene mafakitale akupitiliza kufunafuna zinthu zomwe zimapereka magwiridwe antchito ndi chilengedwe, hpmc imawoneka ngati njira yosiyanasiyana, yotetezeka, komanso yosakhazikika kuti ikonzekere bwino.
