Ukuchongwa komgangatho we-Hydroxypropyl Methyl Selelise

Nye. Umahluko phakathi kwe-hydroxypropyl ye-Hydropylcelsele
1. Imbonakalo: I-Hydroxypropyl ye-Hythylcelcelsele HPMC ikhangela i-fluffy kwaye inesixa se-bulk esisezantsi, sisuka kwi-0.3-0.4G / ml; I-Hydroxypropyl Methylcelcelgalose HPMC inobuqhetseba kwaye ivakalelwa nzima, kwaye kukho umahluko obalulekileyo kwimveliso yokwenyani.

2. Imeko: I-HydroxyPyl ye-Hydropyl Methylcelcelsele hpmc Powder i-fibrod inamachaphaza phantsi kwemakroskopu okanye iglasi yokukhulisa; Ngelixa i-hydroxypropyl methylcelcelsulose hpmc inokubonwa njengezinyibilikisi okanye iikristali phantsi kwemakroskopu okanye iglasi yokukhulisa.

I-3. I-Odor: I-Hydroxypropyl Methylcelcelcelsele HPMC ayinakuhoya ivumba le-ammonia, isitatshi kunye notywala; I-Hydroxypropyl Methylcelcelsulose HPMC inokunuka zonke iintlobo zevumba, nokuba ayinantsingiselo, iya kuziva inzima.

I-4. Isisombululo se-AQUO: I-HYDROXYLLL MONTYLCELCELCELCELXELXEXOE I-HPMC Ascoul icacile, ukuguqula okuphezulu, ireyithi yokugcina amanzi ≥ 97%; I-Hydroxypropyl Methylcelceltulose HPMC ACTME SOCTID, kwaye izinga lokugcina amanzi kunzima ukufikelela kwi-80%.

Okwesibini, ukugcinwa kwamanzi kwe-hydroxypropyl methylcelceluplose hpmc, ukwahlula izibonelelo kunye nezinto ezingalunganga:
Ukugcinwa kwamanzi kwe-Methyl Seler I-Ether phantsi kweemeko zobushushu obuphezulu kubalulekile ukwahlula umgangatho we-methyl seteli. Izinto ezifana neqondo lobushushu lomoya, ubushushu kunye nesantya somoya esinesantya somoya siya kuchaphazela ireyithi yamanzi esinqeni sesamente Ke ngoko, kumaxesha ahlukeneyo, kukho umahluko kumsebenzi wokugcinwa kwamanzi weemveliso ezinomgangatho ofanayo we-HPMC yongezwa. Kumsebenzi othile, umphumo wokugcinwa kwamanzi okutyibilika unokwanda ngokwanda okanye ukwehla kwe-HPMC yongezwa. Imveliso egqwesileyo ye-hydroxylcelcel methylcelcelsele ye-HPMC inokuthi isombulule ngempumelelo ingxaki yokugcinwa kwamanzi phantsi kobushushu obuphakathi.

Umgangatho ophezulu we-methylcelculose unokufana ngokulinganayo kwaye usasazeke ngempumelelo kwizifo zezamente ezisekwe kwi-gypsim kunye ne-cuspping, kwaye inyanzelise ifilimu eqinileyo, kwaye inyanzelise ifilimu ye-hidration, inyanzelise ukomelela komxholo. Umgangatho ophezulu we-hydroxypropyl methylcelcelsele Hpmc, ukufana kwayo kulungile, i-Eyexy kunye ne-Hydroxypropoxy I-Hydrogen Bonds ijika i-Holdrogen Bonds, ngokufezekileyo Ukulawula ukwanda kwamanzi okubangelwa bubushushu obushushu obuphezulu kunye nokufezekisa ukugcinwa kwamanzi.

Ke ngoko, kulwakhiwo oluphezulu lokwakhiwa kweqondo lobushushu, ukuze kufezekiswe imisebenzi yokugcina amanzi, kunyanzelekile ukuba bongeze iimveliso ezikumgangatho we-HPMC kwi-FOTURAS ngokwefom yefomula, kungenjalo, ukuncitshiswa komgangatho, ukuqhekeza, ukungcungcutheka okubangelwa kukomile kakhulu. Iingxaki, kodwa ukwandisa ubunzima bokwakha abasebenzi. Njengoko iqondo lobushushu lihla, inani lamanzi e-HPMC longezwe linokuncitshiswa ngokuthe ngcembe, kwaye kuya kufezekiswa.

Kumzi-mveliso wokwakha, i-Hydroxypropyl Methylcelcelgalose HPMC idla ngokubekwa kumanzi angathathi cala, kwaye imveliso ye-HPMC ichithwe yodwa ukugweba inqanaba lokuchitha. Emva kokuba ibekwe kumanzi angathathi hlangothi kuphela, imveliso ephumela ngokukhawuleza ngaphandle kokusasazeka yimveliso ngaphandle konyango olungaphantsi konyango; Emva kokuba ibekwe kumanzi angathathi hlangothi kuphela, imveliso enokusasazeka kwaye ingabi kunye yimveliso enonyango. Xa umphezulu we-hydropyl ye-hydropylcelcelgalose HPMC ichithwe yedwa, i-subleunt eyodwa inyibilikile ngokukhawuleza kwaye ingenzi ifilimu ngokukhawuleza, ekhokelela ekuchitheni okucothayo kwimveliso yentengiso.

I-Hodroxypropyl ye-Hydroxylcel ye-Methylcelcelsele HPMC I-HPMC I-HPMC Imveliso, kumanzi angathathi cala, amasuntswana athile anokusasazeka ngaphandle kokuvuselelwa, kodwa imveliso yemveliso ayiyi kukhankanywa kwangoko. Emva kokuthoba ixesha elithile, ubume bemichiza yonyango lomhlaba butshatyalalisiwe, kwaye amanzi angawachithe amasuntswana e-HPMP. Ngeli xesha, amasuntswana emveliso sele echithwe ngokupheleleyo kwaye efumana amanzi ngokwaneleyo, ngoko ke imveliso ayiyi kuba nako okanye ivuyiwe emva kokupheliswa. Isantya sokusasazeka kunye nesantya sokuchithwa kuxhomekeka kwinqanaba lonyango lomphezulu. Ukuba impatho yomhlaba incinci, isantya sokusasazeka sicotha kwaye isantya esinamathelayo siyakhawuleza; Ngelixa imveliso enonyango olunzulu lomhlaba lunesantya sokusasazeka ngokukhawuleza kwaye isantya esicothayo. Ukuba ufuna ukwenza olu cekinye lweemveliso zinyibilikisile ngokukhawuleza kule meko, ungalahla inani elincinci lezinto zeAlkaline xa zichithwe wedwa. Imakethi yangoku ihlala ibizwa ngokuba ziimveliso zethutyana. Iimpawu zeemveliso ze-HPMC eziphathwayo ze-HPMC zezi: Kwisisombululo esinamandla, amasuntswana anokusasazeka, anganyibilikisa ngokukhawuleza kwi-Alkaline State, kwaye anyibilike kancinci kwimeko engathathi hlangothi.

Iimpawu ze-HydroxyPyl ye-HydropylCylcelceLcelse HPMC yile: I-Aunticle enye inyibilika ngokukhawuleza kwi-acidic, ialkaline, kunye namazwe angathathi ntweni, kodwa ezikhokelela ekuqokeleleni nasekuhlanjuleni. Ngokwenyani, emva kokusasazwa ngokwasemzimbeni kolu ngcelele lweemveliso kunye namasuntswana aqinileyo anjengomgubo werabha, isamente, isanti, njl njl. Xa kuyimfuneko ukunyibilikisa iimveliso ze-HPMC ngokwahlukeneyo, olu cekisiweyo lweemveliso kufuneka lusetyenziswe ngononophelo, njengoko luya kubamba kunye. Ukuba kuyimfuneko ukuchitha i-HydroxyPyl ye-HydroxylCopyl Methylcelsulose HPMC Imveliso yemveliso eyahlukileyo

Ngokwakuko ukusebenza kwemveliso, olu cekishiweyo lweemveliso zihlala zinyibilikisiwe emva kokuba zisasazeke ezinye izinto eziqingqiweyo phantsi kweemeko ze-Alkaline, kwaye izinga lokuchithwa kwayo akukho lahlukile kwezo iimveliso ezingachazwanga. Ikwafanelekeka ukusetyenziswa kwiimveliso eziphethwehlisi zodwa, ngaphandle kokukhonkotha okanye iziqhushumbisi. Imodeli ethile yemveliso inokukhethwa ngokwexabiso lokuchithwa okufunwa ngulwakhiwo.

Ngexesha lenkqubo yokwakha, nokuba luhlobo lwesamente okanye isilayidi se-gypsim esekwe kwi-Gyppum, uninzi lwazo ziinkqubo ze-alkali, kunye nexabiso le-HPMC lincinci kakhulu, elinokusasazeka kakhulu kwezi ntshukumo. Xa amanzi esongezwa, i-HPMC iya kukhawuleza inyibilikise.
