Inkqubo yeMveliso ye-HPMC kunye nokuhamba

I-Hydroxypropyl Methylcelcelsele (i-HPMC) yi-polymer eguquguqukayo esetyenziswa ngokubanzi kwiindawo zamayeza, ukutya, ukwakhiwa, amanye amashishini ahlukeneyo. Iipropathi zayo ezizodwa zenza ukuba zibeluleka kwizicelo ezisusela kwiinkqubo zokuzibandakanya eziya kwiarhente zokubalelwa kwiimveliso zokutya kwiimveliso zokutya. Ukuqonda inkqubo yokuphuhlisa kunye nokuhamba kwe-HPMC kubalulekile ekuqinisekiseni umgangatho wemveliso kunye nokungaguquguquki.

1.Row yokhetho lwezinto ezibonakalayo:
a. Umthombo weSeluplose: I-HPMC isuselwa kwisellulose, ifunyenwe kwi-Pulp Pulp okanye i-Cotton Listry.
b. Iimfuneko zokucoceka: Ukucoceka okuphezulu kwesellulose kubalulekile ukuqinisekisa ukuba umgangatho we-HPMC. Ukungcola kunokuchaphazela ukusebenza kunye nezinto zemveliso yokugqibela.
c. Isidanga sokufakwa endaweni Abavelisi bakhetha ukufobeli ngamanqanaba e-DS efanelekileyo esekwe kwisicelo esifunayo.

2.Ngerisical reaction:
a. I-Arhente yokukhuphela i-e-propylene oxide kunye ne-methyl chloride isetyenziswa iiarhente zokuthengiswa kwe-imeyile kwimveliso ye-HPMC.
b. Iimeko zokuphendula: Ukuphendula kwe-Etherisation kwenzeka phantsi kobushushu obulawulwayo, uxinzelelo, kunye neemeko ze-ps ukufezekisa i-DS enqwenelekayo.
c. I-Catalysts: I-Alkali Catalysts efana neSodium hydroxide okanye i-potassium hydroxide ihlala isebenza ukuqhuba isivumelwano sokuphendula.
d. Ukubeka iliso: Ukubeka iliso esweni okuqhubekayo kweeparamitha zokuphendula kubalulekile ukuqinisekisa ukuba i-DS engaguqukiyo kunye nemveliso yomgangatho.

3.Ukuhlala kunye nokuhlamba:
a. Ukususwa kokungcola: I-HUDMC ye-HPMC iphantsi kweenkqubo zokucoca ukususa iirejista ezingasetyenziswayo, kwiimveliso, kunye nokungcola.
b. Amanyathelo okuhlamba: Ukuhlamba okuninzi okuhlambayo kunye namanzi okanye izinyibilikisi zezinto eziphilayo zenziwa ukuze kucoce i-HPMC kwaye kufezekise inqanaba lokucoceka olufunwayo.
c. Ukonakalisa kunye nokomisa: Iindlela zokuzila eziqengqelekayo ziqeshwa ukwahlula i-HPMC ukusuka kwi-HPMC ukusuka kwi-HPMC ukusuka kwi-slisns yokuhlamba, ilandelwe ngokomile ukufumana imveliso yokugqibela kwi-powder okanye kwifom yegranular.

I-4.PARTACICINCIFICINTER RAND:
a. Ukugaya kunye nokugaya: Amasuntswana e-HPMC ahlala ephantsi kwe-grind kunye neenkqubo zokugaya ukulawula ubungakanani bobungakanani be-parta.
b. Ukuhleba: Iindlela zokuhleba ziyaqeshwa ukuqinisekisa ukuba ubungakanani be-irform ye-ilayiselayo kwaye basuse amasuntswana aphezulu.
c. I-Precticle Sperication: Iindlela zokuhlalutya ubungakanani be-paricle ezifana ne-Laser Elfraction okanye i-microscopy isetyenziselwa ukuvelisa amasuntswana e-HPMC kwaye aqiniseke ukubambelela kunyango.

5.Ngalo kunye noKwenziwayo:
a. Ukudityaniswa kokudityaniswa: I-HPMC inokudityaniswa nabanye abanomdla okanye i-songers zokulungisa iipropathi zayo zezicelo ezithile.
b. I-homogesization: Iinkqubo zokudibanisa iinkqubo zokuqinisekisa ukusasazwa kwe-HPMC ngaphakathi kwenkqubo yokufezekisa iimpawu zomsebenzi ozifunayo.
c. Ulungiselelo lwenkqubo

Ulawulo lomhlaba:
a. Uvavanyo oluhlalutyo: Iindlela ezahlukeneyo zokuhlalutya ezifana ne-infrared morescopy, i-chromatography, kwaye i-chromatolography, kunye ne-geology iqeshwe kulawulo oluphambili lwe-HPMC.
b. I-DS Ukuzimisela: I-DS ye-HPMC ilinganiswe rhoqo ukuqinisekisa ukungavisisani kunye nokubambelela kunyango.
c. Uhlalutyo lokuNgcolwa: Amanqanaba eZinyibilikayo, umxholo wensimbi onzima, kunye nokucoceka kwe-ratial ijongiwe ukuqinisekisa ukhuseleko lwemveliso kunye nokuthotyelwa kwemigangatho yolawulo.

7.Ukugcinwa kunye nokugcinwa:
a. Izinto zokupakisha: I-HPMC idla ngokubangelwa zizikhongozeli zokunganyangekiyo ukuthintela ukonakaliswa nokugcina ingqibelelo.
b. Iimeko zokugcina: I-HPMC kufuneka igcinwe kwindawo eyomileyo, epholileyo kude kukhawulezise ngokuthe ngqo ukuphelisa ukuthambeka komswakama kunye nokuphefumla.
c. Ubomi beshellopu: I-HPMC ePhephakileyo kwaye igcinwe ngokufanelekileyo i-HPMC inokubakho kwiinyanga ezininzi ukuya kwiminyaka, kuxhomekeka kwiimeko zokugcina kunye nokugcina iimeko.

Inkqubo yokwenziwa kwe-HPMC ibandakanya uthotho lwamanyathelo achazwe kakuhle, ukusuka ekukhetheni izinto ezibonakalayo kwipakethi yokugqibela yemveliso. Inqanaba ngalinye lifuna ulawulo ngononophelo kunye nokubeka iliso ukuqinisekisa umgangatho wemveliso, ukungqinelana kunye nokuthotyelwa kwemigangatho yolawulo. Ngokuqonda inkqubo yokwenziwa kunye nokuhamba kwe-HPMC, abavelisi banokwandisa ukusebenza ngempumelelo kunye nokuhlangabezana neemfuno ezahlukeneyo kumashishini ahlukeneyo.
