Makhalidwe a kutentha kwaukadaulo wa hydroxypropyll methylcellulose

Hydroxypropyl methylcellulose (hpmc)ndi chinthu chofunikira cha mankhwala, chimagwiritsidwa ntchito kwambiri pazomangira, mankhwala, chakudya ndi minda ina. Makamaka mu makampani omanga, hpmc imagwiritsidwa ntchito kwambiri chifukwa cha ntchito yake yabwino. Tekinoloji yotentha kwambiri imagwira ntchito yofunika pakupanga ndi kugwiritsa ntchito HPMC.

1. Udindo wa ukadaulo wambiri wamakono ku HPMC

Cinducehydropyl methylcellulose imapezeka ndi mitundu ingapo ya mankhwala monga kusinthidwa kwa cellulose ndi kusinthika kwa cellulose. Ukadaulo wambiri umagwiritsidwa ntchito makamaka mu kusungunuka, kuyanika ndi kuumba magawo a machitidwe. Chithandizo cha kutentha kwambiri sichitha kuthamanga chifukwa cha zomwe mungachite, komanso sinthani chiyero ndi kukhazikika kwa malonda.

Kuchita bwino

Pansi pa kutentha kwambiri, zomwe zimachitika mu cellulose ndi sodium hydroxide zimathamangitsidwa, zomwe zimalimbikitsa kusintha kwa ma cellose mkati mwa ma cellose (ds) ndi kufanana kwa HPMC.

Chotsani zosayera

Malo otentha kwambiri amatha kuchotsa bwino zinthu zomwe zimapangidwazo, monga zosakwanira alkali yankho ndi zosungunulira, ndikusintha chiyero cha HPMC.

Kupuma bwino Kuuma

Pa nthawi yayitali kutentha kwambiri, chinyontho cha HPMC chimatuluka mwachangu, kupewa malonda kuchokera kuwuma kapena kuwonongeka kwa kutentha pang'ono, ndikuwongolera kukhazikika ndikusunga magwiridwe antchito.

2. Malingaliro a ukadaulo wamatekiti-kutentha kwambiri pakuchita kwa HPMC

Tekinolojekiti yamagetsi yamagetsi sizimangokhudza kapangidwe ka HPMC, komanso zimakhudzanso kwambiri mankhwala ndi zotsatira zake.

Kusintha kwa ViscCon

Njira yotentha kwambiri imatha kuyendetsa bwino magawano ochepetsa thupi la HPMC, potero kusintha mamasukidwe ake. Kutentha kwambiri kumathandizira kuchepetsa kuthekera kwa kuwonongeka kwa ma valinec unyolo, kumapangitsa mamasukidwe a HPMC mu njira yokhazikika.

Kubwezeretsa Kutentha

Kukhazikika kwa matenthedwe kwa HPMC kumasinthidwa kwambiri kudzera mu chithandizo chamakedza. Pakumanga matope ndi tiile, hpmc imatha kukhalabe ndi zotsatsa zabwino komanso zida zotsutsana ndi kutentha kwambiri.

Kusungunuka Kwambiri

Panthawi yotsatsa kutentha kwambiri, micrestructuction ya HPMC imakonzedwa, ndikupangitsa kuti ikhale yosungunuka m'madzi ozizira. Makamaka pamayendedwe otsika-kutentha, hpmc imatha kusungunuka mwachangu ndikupanga yankho la colloml.

3.. Kugwiritsa ntchito mwachindunji kwa matekitidwe apamwamba kwambiri mu hpmc wopanga

Gawo la Kuzindikira

Mwa kukwaniritsa chizindikiritso kutentha kwambiri kwa 80-100 ° C, m'malo mwa hydroxypyl ndi ma methyl amatha kupitilizidwa, kotero kuti HPMC ili ndi gawo labwino kwambiri.

Kuyanika ndi kuphwanya gawo

Tekinoloji yowuma pamtunda pamwamba pa 120 ° C sangathe kungochotsa chinyezi, komanso kupewa ufa wa hpmc kuchokera pakuwuma. Pambuyo pake, kutentha kwadzuwa kumagwiritsidwa ntchito kupanga tinthu tambiri toyambitsa matenda a HPMC ufa wowoneka bwino komanso yunifolomu, ndipo kuphatikizika kwa chinthucho kumachitika.

Kutentha kwa kutentha

Pamene HPMC imagwiritsidwa ntchito popanga zinthu zomanga kapena zokutira, kutentha kwatentha kumatha kuthana ndi zovuta zake, kukana madzi ndi ntchito zosungidwa madzi, ndikuwonetsetsa kuti zomanga zabwino m'malo mwa zinthu zovuta.

4. Ubwino wamatenthedwe kambiri mu HPMC Purses

Zipangizo Zomanga

Pansi pa kutentha kwambiri, HPMC imawonetsa bwino kwambiri kuti madzi osungidwa ndi madzi osungidwa ndi matope, amaletsa matope kuchokera kuthyathyathya komanso kusweka.

Utoto wa utoto

HPMC yophatikizika ndi kutentha kwambiri kumakhala ndi zovuta zowongolera komanso zoletsa za utoto wa mochedwa, zomwe zimawongolera chotsatsa ndikuvala kukana zokutira.

Makampani opanga mankhwala

Technology Wamphumphulika

Kugwiritsa ntchito matebulo kwambiri aukadaulo wahydroxypypyl methylcelluloseSikuti zimangokongoletsa mphamvu, komanso zimathandizanso kugwira ntchito yogulitsa. Kudzera kutentha kwambiri, mamasukidwe, kukhazikika kwa ma hpmc kwakhala kukulimbikitsidwa kwambiri, ndikupangitsa kuti akhale ndi chiyembekezo chachikulu mu minda yomanga, zokutira ndi mankhwala. M'tsogolomu, chifukwa chofala kwambiri chamatelenoloji, magwiridwe antchito a HPMC idzatukuka, ndikupanga zopereka zazikulu pakukula kwa zinthu zobiriwira komanso zachilengedwe zachilengedwe.
