Yintoni eyona nto iphambili ye-hydroxypropyl methylcelgulose?

I-HPMC isetyenziswa ngokubanzi kwizixhobo zokwakha, iingubo, i-reatsins, i-ceramic, i-ceramics, ukutya, izibalo, i-cosmetics, amanye amashishini. I-HPMC inokwahlulwa ibe liqela lemizi-mveliso, kwibakala lokutya kunye namachiza amayeza ngokwesicelo.

I-2Shdroxypropyl Methylcelceltulose yahlulwe yangamagama aliqela, kwaye yintoni umahluko ekusebenziseni kwabo?

I-HPMC inokwahlulwa kudidi lwangoko (igama le-Brand Storlix "s") kunye nohlobo olushushu. Iimveliso zemodi zethutyana zisasaza ngokukhawuleza emanzini abandayo kwaye zinyamalala emanzini. Ngeli xesha, ulwelo alunanto yokuba i-HPMC ichithwa njengamanzi ngaphandle kokupheliswa kokwenene. Malunga (ishukumisa) imizuzu emi-2, i-viscosity ye-allicofity ngokuthe ngcembe inyuka, yenza i-collous emhlophe ebonakalayo. Iimveliso ezishushu ezinyibilikayo, xa zidibene namanzi abandayo, zinokusasaza ngokukhawuleza emanzini ashushu kwaye zinyamalala emanzini ashushu. Xa iqondo lobushushu liye kwiqondo lokushisa (ngokweqondo lobushushu be-gene), i-vickosity iya kuvela kancinci ide ibonakale i-collous engabonakaliyo.

Zithini iindlela zokuchitha i-3 ye-hydroxypropyl methylcelcelcelcelcelcelcelgalose?

1) Zonke iimodeli zinokongezwa kwizinto zendlela eyomileyo yokuxuba;
2) Xa kufuneka kongezwe ngokuthe ngqo kwisisombululo esiqhelekileyo seqondo eliqhelekileyo, kungcono ukusebenzisa uhlobo lokusasaza kwamanzi olubandayo, kwaye ihlala ithatha imizuzu eli-10 ukuya kwe-90 ukuya kuthi ga emva kongeziweyo
I-3) Imodeli yesiqhelo ishukunyisiwe kwaye isasazeka ngamanzi ashushu kuqala, emva koko inokutshitshiswa emva kongeza amanzi abandayo ukuze avuse kwaye apholile;
4) Ukuba kukho ukungavisisani kunye nokungenisa ngexesha lokupheliswa, kungenxa yokuba ukuvuselela akonelanga okanye imodeli eqhelekileyo yongezwa ngokuthe ngqo kumanzi abandayo. Ngeli xesha, kufuneka ishukunyiswe ngokukhawuleza. i
5) Ukuba amaqabu aveliswa ngexesha lokupheliswa, banokushiywa ukuba bame iiyure ezi-2 ukuya kwezi-12 (ixesha elithile ligqitywe kukungqinelana kwesisombululo) okanye ukususwa, njl njl. i

4 Ugweba njani umgangatho we-hydroxypropyl methylcelcelceluplose nangempeleni?

1) Ubumhlophe, nangona ubumhlophe abunakufumanisa ukuba i-HPMC kulula ukuyisebenzisa, kwaye ukuba i-Whitering iyongezwa kwinkqubo yemveliso, iya kuchaphazela umgangatho wayo, kodwa uninzi lweemveliso ezilungileyo lube mhlophe mhlophe.
2) Ukuhlelwa: Ukulunga kwe-HPMC ngokubanzi kune-80 Mesh kunye ne-100 Mesh, i-120 mesh incinci, imbumbulula ingcono.
3) Ukukhanya ukukhanya: Emva kokuba i-HPMC ibekwe emanzini ukwenza i-colloid ebonakalayo, jonga ukukhanya kwayo. Ukuqaqamba kokukhanya okukhulu, okungcono, kubonisa ukuba kukho ukungazinzi okuncinci kuyo, kwaye ukuhanjiswa kweesanda ezithe nkqo zihlala zilungile. , I-proctor ethe tyaba imbi kakhulu, kodwa ayithethi ukuba umgangatho wokwenza nkqo ungcono kuneso sabemihlaba ethe nkqo, kwaye zininzi izinto zokuchonga umgangatho wemveliso.
4) Ukuqina okukodwa: Kuyinto enkulu kumxokelelwane othile, oyena mntu uphambili. Ukuphakama okuphezulu, ukuphakama komxholo we-hydroxypropy kwimveliso. Ngaphezulu komxholo we-hydroxypropy, kungcono ukugcinwa kwamanzi.

18 Nguwuphi umahluko phakathi kwe-hydroxypropyl methylcelceluplose kunye ne-mc:

I-MC ye-methyl seluplose, eyenziwe nge-tartulose ether ngokuphatha i-cotton ecocekileyo kunye ne-Alkali, esebenzisa i-methane chloride njenge-arhente yokuphendula, kwaye ithathe uthotho lweempendulo. Ngokubanzi, inqanaba lokufakwa endaweni le-1.6-2.0, kwaye i-solinoty iyahluka ngeenciniba ezahlukeneyo zokufaka endaweni. Eyahlukileyo, yey yey-ionlulose ether.

. Ngokubanzi, ukuba isixa esongezelelekileyo sikhulu, ukulunga kuncinci, kwaye i-vickosity inkulu, inqanaba lokugcina amanzi liphezulu. Phakathi kwabo, isixa esongeneyo sinempembelelo enkulu kwiqondo lokugcina amanzi. I-viscosity ayihambelani nenqanaba lokugcina amanzi. Inqanaba lokuchithwa ikakhulu lixhomekeke kumphezulu weeseli zefowuni. Isidanga sokutshintsha kunye nokungakhathali. Phakathi kwezi zinto zingentla kwe-Sethes, iMethyl Selelose kunye neHydroxypropyl Methyl Selelose anemilinganiselo ephezulu yokugcina amanzi.
. Isisombululo se-ACTEAFOO EZIQHELEKILEYO ZIYAKUZINYANGO KUTSHINTSHO KUNYE NOBUCHULE B = 3-12. Ihambelana ngokuchanekileyo nesitatshi, njl njl. Xa iqondo lobushushu xa iqondo lobushushu lifikelelwe, ukumelana kuya kwenzeka.
(3) Utshintsho kubushushu luya kuchaphazela kakubi inqanaba lokugcinwa kwamanzi kwi-methyl seluplose. Ngokubanzi, amaqondo obushushu aphezulu, owona manyathelo okugcina amanzi. Ukuba ubushushu obuphango bugqitha i-40 degrees, ukugcinwa kwamanzi kwe-methyl seluplose kuya kuncitshiswa kakhulu, kuya kuchaphazela kakhulu ukwakhiwa kodaka.
(4) I-Methyl Selelose inefuthe elibonakalayo kulwakhiwo kunye nokubulala. Umlinganiso apha ubhekisa kumandla okuhlaselwa avakalelwa kukubaluleka komsebenzi wesicelo kunye nodonga, oko kukuthi, ukumelana nodaka. Ukunamathela phezulu, ukumelana nodaka komkhulu, namandla afunwa ngabasebenzi ngenkqubo yokusetyenziswa kwabakhulu, kwaye ukwakhiwa kodaka kuhlwempuzekile.
