Ungawugweba njani uMgangatho wemveliso

I-Hydroxypropyl Methylcelceltulose (HPMC) yizixhobo ezibalulekileyo zeekhemikhali ezisetyenziswa ngokubanzi ekwakhiweni, amayeza, ukutya, iingubo kunye namanye amasimi. Ukugweba umgangatho weemveliso ze-HPMC, kuyimfuneko ukuqhuba uvavanyo olubanzi ukusuka kwimiba emininzi enjengeempawu zayo zomzimba kunye neekhemikhali, iziphumo ezichanekileyo.

I-1. Iimpawu ezimbonakalo
Umbala kunye noRhulumente: I-HPMC ephezulu ye-HPMC ihlala imhlophe okanye i-off-whider emhlophe okanye igranugules, ngombala ofanayo kwaye kungabikho nto iphosakeleyo kumphezulu. Umbala omnyama kakhulu okanye amabala anokubonisa ubunyulu obunyulu olwenziweyo okanye ukungalunganga kwenkqubo yemveliso.
I-Odor: I-HPMC ephezulu ye-HPMC ayinayo iodor ebonakalayo. Ukuba kukho nayiphi na i-odor, inokubonisa ubukho bokungcola okanye intsalela yekhemikhali kwinkqubo yemveliso.

2. Izalathi zeNkqubo yeNtloko yeShemikhali
I-Viskosity: I-Viscosity yipharamitha ebalulekileyo ye-HPMC, echaphazela ngqo ukusebenza kwayo kwisicelo. Ihlala ivavanywa ngumboniso ojikelezayo okanye i-visment ye-brookfield. I-viscosity ye-HPMC ekumgangatho ophezulu kufuneka zizinzile, kwaye umatshini wempazamo phakathi kwexabiso lovavanyo kunye nexabiso elifanelekileyo lincinci (ngokubanzi alikho ngaphezulu kwe- ± 10%).
Isidanga sokufakwa endaweni: Ukusebenza kwe-HPMC kunxulumene ngokusondeleyo nenqanaba le-AFTIMSY NE-HYDROXYPOPL. Umxholo we-Eaccoxy uhlala kwi-19-30%, kwaye umxholo we-hydroxypropyl yi-4-12%. Isidanga esisezantsi kakhulu okanye esikhulu kakhulu siya kuchaphazela ukona kunye nokuzinza kwemveliso yemveliso.
Umxholo womswakama: Umxholo wokufuma awusekho ngaphezulu kwe-5%. Umxholo omkhulu kakhulu uya kuchaphazela uzinzo lokugcina kunye nesiphumo se-HPMC.
Umxholo we-Ash: i-Ash ASh ikakhulu ibonisa umxholo wezinto ezingcolileyo kwi-HPMC. Umxholo we-ash weemveliso ezisemgangathweni kakhulu kufuneka ungaphantsi kwe-1%.
Ukuluka: I-HPMC kufuneka ibe ne-smolubious elungileyo, kulula ukusasazeka kumanzi abandayo, kwaye yenze isisombululo esibonakalayo nesingafaniyo. Ukuba amasuntswana acacileyo okanye ukwenziwa kwe-scaccuiption avele ngexesha lenkqubo yokutshintsha, kuthetha ukuba umgangatho wemveliso uhlwempuzekile.

3. Umsebenzi osebenzayo
Ukugcinwa kwamanzi: Kwizicelo zokwakha, ukugcinwa kwamanzi kwi-HPMC kuchaphazela ngokuthe ngqo ukusebenza kokwakha. Iqondo lokugcina amanzi esimemeni okanye i-gypsum imiselwe uvavanyo (ngokubanzi kufuneka libe ngaphezulu kwe-90%) ukugweba umgangatho wayo.
Umsebenzi wokutyibilika Ukuba ukuxolelwa okanye ukuveza kuyancipha, kunokubonisa uzinzo lwemveliso.
Iipropathi ezenziweyo zefilimu: I-HPMC ineepropathi ezifanelekileyo zefilimu kwaye kufuneka iguquguqukele kwaye iguquguqukayo emva kokuqulunqwa kwefilimu. Ukungalingani kwefilimu engalinganiyo okanye ukufumba ifilimu kubonisa umgangatho wemveliso.
Uzinzo lwe-therm

4. Iindlela zokuvavanywa kunye nemigangatho
Uvavanyo lwelebhu: Sebenzisa i-vissifiemeter, ii-spectrometer, i-Ash Ashlahlaluts kunye nezinye izixhobo zokulinganisa ngokuchanekileyo i-HPMC yokuqinisekisa ukuba imveliso ihlangabezana nemigangatho.
Uvavanyo lwesicelo: Yongeza i-HPMC kwinkqubo yesicelo ethile (ezinje ngodaka lwesakhiwo okanye ipeyinti) kwaye uvavanye ukugcinwa kwamanzi, ukusasazeka, ezinye iipropathi ngokusebenzisa iimeko zokusetyenziswa kwezenyani.
Imigangatho yamazwe ngamazwe: Iimveliso ezikumgangatho we-HPMC zihlala zihlangabezane nemigangatho efanelekileyo efana ne-ISO, i-USP, ep, njl. Njl.

5. Uzinzo lwemveliso
Umsebenzi wokugcina ixesha elide: I-HPMC ephezulu ye-HPMC kufuneka ibe nakho ukugcina izinto ezizinzileyo zomzimba kunye neekhemikhali kunye nokusebenza kwesicelo ngexesha lokugcina. Ukukhawulezisa ukwaluphala kusetyenziselwa ukuvavanya utshintsho lwentsebenzo yalo phantsi kobushushu obuphezulu kunye neemeko eziphakamileyo zokufuma.
Ukunganyangeki kwetyuwa: Izinto zetyuwa zinokubakho kwezinye izinto ezisebenza. I-HPMC ekumgangatho ophezulu i-HPMC kufuneka ikwazi ukugcina isombo esifanelekileyo kunye nokubonakala kwezisombululo zetyuwa.

I-6. Inkqubo yokuvelisa umthengisi kunye nolawulo lomgangatho
Ukukhetha izinto ezibonakalayo: Ukuveliswa kwe-HPMC ekumgangatho ophezulu kufuna izinto ezingafunekiyo zeSelsulose, kwaye umgangatho wezixhobo eziluhlaza unefuthe elibonakalayo kwimveliso yokugqibela.
Inkqubo yemveliso: Inkqubo yemveliso yanamhlanje kunye nolawulo olungqongqo sesiqinisekiso se-HPMC esemgangathweni. Abathengisi abakumgangatho ophezulu kufuneka babe nemigca yokuvelisa abazinzileyo kunye nezixhobo zokuvavanya.
Ukuzinza kwe-BHATCT: Ngokuthelekisa intsebenzo eyahlukeneyo yeemveliso, kunokugwetywa ukuba inkqubo yemveliso yomthengisi iyazinza.

I-7. Impendulo yomsebenzisi kunye ne-paidition yentengiso
UVAVANYO LWEZITRIKI: Esona sicelo semali kunye nengxelo yabasebenzisi zingabalulekanga ekugwebeni ukugweba umgangatho weemveliso ze-HPMC.
Ukwamkelwa kweMakethi: Iimveliso ze-HPMC ze-rands eyaziwayo okanye isetyenziswe ngokubanzi kumashishini amaninzi amaninzi zihlala zisemgangathweni othembekileyo.

8. Izilumkiso
Xa kuthengwa i-HPMC, iimfuno zesicelo ezithile kufuneka zicacisiwe kwaye iimveliso zenkcazo ezifanelekileyo ziya kukhethwa. Kwangelo xesha, ukwenziwa kwemveliso kunokuqinisekiswa ngakumbi ngovavanyo lwe-batch encinci ukuthintela ilahleko ebangelwa kukungasebenzi kakuhle.
