Hydroxypyl methylcellose (hpmc)Shin wani yanki ne wanda ake amfani da shi mai narkewa, ana amfani dashi sosai a cikin magunguna, abinci, kayan gini, kayan gini da sauran filayen. HPMC yana da halaye masu kyau da halaye na danko kuma suna iya samar da ingantaccen maganin matsalar, saboda haka yana taka muhimmiyar rawa a aikace-aikace da yawa. Don ba da cikakken wasa zuwa aikin HPMC, hanyar rushewa ta zama mahimmanci musamman.
1. Hanyar rushewa na al'ada
HPMC za'a iya narkar da a cikin ruwan sanyi, amma yawanci ana buƙatar wasu ƙwarewa don guje wa agglomerer. Domin inganta tasirin rushewa, ana iya amfani da matakai masu zuwa:
Mataki na 1: Addara HPMC zuwa ruwa
A zazzabi a daki, da farko yayyafa hpmc a ko'ina a saman ruwa don gujewa zuba babban adadin hpmc a cikin ruwa a lokaci guda. Saboda HPMC ne mai polymer, kai tsaye yana ƙara yawan adadin HPMAC zai haifar da ɗaukar ruwa kuma ya zube cikin ruwa don samar da kayan gel-kamar abu.
Mataki na 2: Matsa
Bayan ƙara HPMC, ci gaba da motsa jiki a hankali. Saboda hpmc yana da kyawawan barbashi, zai kumbura bayan shan ruwa don samar da abu mai kyau. Matsa tana taimakawa wajen hana HPMC daga agglomatus zuwa clumps.
Mataki na 3: Tsaya da more rayuwa
Idan ba a rushe HPMC gaba ba, za a iya barin mafita don tsayawa na ɗan lokaci sannan kuma ci gaba da motsa. Yawancin lokaci za a narkar da ƙasa cikin 'yan awanni kaɗan.
Wannan hanyar ta dace da lokutan inda ba a buƙatar dumama ba, amma yana ɗaukar lokaci mai tsawo kafin a narkar da hpmc gaba ɗaya.
2. Hanyar Rashin Gasar Ruwa
HPMC ta narke cikin sauri a cikin ruwan dumi, don haka dumama ruwan zafin jiki na iya hanzarta aiwatar da rushewa. Abubuwan da ake amfani da shi na yau da kullun zafin jiki na ruwa ne 50-70 ℃, amma maɗaurin zazzabi (kamar sama da 80 ℃) na iya haifar da HPMC don ƙasƙantar da HPMC don ƙasƙantar da HPMC zuwa ƙasata.
Mataki na 1: ruwa mai dumama
Zafafa ruwa zuwa kusan 50 ℃ kuma ku kiyaye shi akai.
Mataki na 2: kara HPMC
Yayyafa hpmc a hankali a cikin ruwan zafi. Sakamakon yawan zafin jiki, HPMC zai watsa mafi sauƙi, rage agglomeration.
Mataki na 3: Matsa
Bayan ƙara HPMC, ci gaba da motsa mafita. Haɗin dumama da motsa su na iya haɓaka rushewar HPMC.
Mataki na 4: Kula da zazzabi kuma ci gaba da motsawa
Kuna iya kula da wani zazzabi kuma ku ci gaba da motsawa har sai HPMC ya narke gaba ɗaya.
3. Hanyar rushewa
HPMC za a iya narkar da ba za a iya narkar da HPMC ba kawai cikin ruwa ba, har ma a cikin wasu cututtukan giya (kamar ethanol). Babban amfani da rushewar rushewa hanyar lalata barasa shine cewa zai iya inganta ƙididdigar da watsawa na HPMC, musamman don tsarin da ke cikin abun ciki na ruwa.
Mataki na 1: Zabi wani masa mai dacewa
Ruwan giya kamar ethanol da isopropannol galibi ana amfani dasu don narke HPMAC. Gabaɗaya magana, 70-90% maganin ethanol yana da tasiri mafi kyau akan narkar da HPMC.
Mataki na 2: Haduwar
Sannu a hankali yayyafa hpmc cikin giya mai ƙarfi, motsawa yayin ƙara don tabbatar da cewa HPMC ya tarwatsa shi sosai.
Mataki na 3: Tsayawa da motsawa
Tsarin barasa da ke haifar da narkar da HPMC yana da sauri, kuma yawanci yana ɗaukar minutesan mintuna kaɗan don samun cikakkiyar rushewa.
Ana amfani da hanyar rushewar barasa a cikin yanayin aikace-aikacen da ke buƙatar rikitar da sauri da ƙananan abubuwan ruwa.

Wani lokacin hpmc an narkar da a cikin cakuda wani rabo na ruwa da sauran ƙarfi. Wannan hanyar tana dacewa musamman don yanayi inda danko na mafita ko adadin rushewar da ake buƙatar gyara. Hanyoyin gama gari sun haɗa da acetone, ethanol, da sauransu.
Mataki na 1: Shirya maganin
Zabi wani rabo mai dacewa da ruwa (misali 50% na ruwa, 50% sauran ƙarfi) da zafi zuwa zazzabi da ya dace.
Mataki na 2: kara HPMC
Yayin da motsa jiki, sannu a hankali ƙara HPMC don tabbatar da jujjuyawar sutura.
Mataki na 3: Gaba
Kamar yadda ake buƙata, da rabo na ruwa ko sauran ƙarfi za a iya ƙaruwa don daidaita kariyar da danko na HPMC.
Wannan hanyar ta dace da lokutan da aka ƙara yawan ƙwayar cuta don mafita na ruwa don inganta raguwar rushewa ko daidaita kaddarorin.
5. Hanyar Karkacewa Downuwa
Yin amfani da illolinancin yanayin dan tayi na duban dan tayi, Hanyar rarrabewa na ultrasonic, zai iya hanzarta kawar da rushewar HPMC. Wannan hanyar tana dacewa musamman ga adadin HPMC waɗanda ke buƙatar narkar da sauri, kuma suna iya rage matsalar agglomerational da zata iya faruwa yayin motsa rai.
Mataki na 1: Shirya maganin
Sanya HPMC zuwa adadin da ya dace na ruwa ko ruwa mai canzawa.
Mataki na 2: Jiyya na Ultrasonic
Yi amfani da tsabtace ultrasonic ko narkewa na ultrasonic kuma suna bi da shi bisa ƙarfin saiti da lokaci. Tasirin oscillation na duban dan tayi na iya hanzarta hanzarta tsarin rushewar HPMC.
Mataki na 3: Duba tasirin rushewa
Bayan jiyya na ultrasonic, duba ko maganin an narkar da shi gaba ɗaya. Idan akwai wani sashi na rashin daidaituwa, za'a iya sake yin jiyya na ultrasonic.
Wannan hanyar ta dace da aikace-aikacen da suke buƙatar ingantaccen tsari da sauri.
6. Daidai kafin rushe
Domin gujewaHpmCAgglomeration ko wahala a cikin rushewa, ana iya amfani da wasu hanyoyin maganganu, kamar hadawa da hpmc da farko, ko bushewa hpmc kafin ƙara sauran ƙarfi. Wadannan matakai masu kyau na iya inganta matsalar HPMC.
Akwai hanyoyi da yawa don soke HPMC. Zabi hanyar rarrabuwa ta dace yana iya inganta ingantaccen yanayin rushewa da ingancin samfurin. Hanyar rushewa zazzage dakin ya dace da yanayin masarufi, hanyar rushewar ruwan sanyi na iya hanzarta aiwatar da katsewa, kuma hanyar rushewar rasuwar barasa da kuma hanyar da ke haɗuwa da ta dace da rushewa da buƙatu na musamman. A ultrasonic-taimaka hanyar warware hanya ce mai amfani don magance matsalar rushewar da yawa na HPMC. Dangane da takamaiman bukatun aikace-aikacen, zaɓi zaɓi na hanyar rushewar da ya dace na iya tabbatar da mafi kyawun aikin HPMC a filaye daban-daban.
