Zithini izibonelelo zokusebenzisa i-HELMPME ephezulu ye-hpmc ecekeceke

Sebenzisa i-Ilupmm ekumgangatho ophezulu iHPMC (Hydroxypropyl MethylcelceLtulose I-HPMC ikakhulu idlala indima yokutyibilika, ukugcinwa kwamanzi, i-qubring, i-boung, njl njl.

1. Ukugcinwa kwamanzi

Ukugcinwa kwamanzi i-HPMC yenye yezona mpawu zibalulekileyo. Engutyeni yesamente, ukugcinwa kwamanzi kubhekiswa kubuchule bezinto zokugcina ukufuma. Oku kunefuthe elibonakalayo ekusebenzeni kodaka. I-HPMC inokukunciphisa ukuphulukana kwamanzi ngexesha lokwakhiwa ngokwandisa inqanaba lokugcina amanzi kodaka, ngaloo ndlela beqinisekisa ukusebenza kodaka. Izibonelelo eziphambili zokugcinwa kwamanzi zibandakanya:

Ixesha elandisiweyo: Kuba amanzi akhutshiwe ngokuthe ngcembe, abasebenzi banokufumana ixesha elingakumbi lokuhlengahlengisa kunye nokwenza udaka, ngakumbi kubushushu obuphezulu okanye indawo eyomileyo.
Thintela ukuqhekeka: Ngexesha lenkqubo yokukhula, ukuphulukana namanzi ngokuthe ngcembe yeyona nto iphambili kodaka. I-HPMC inokugcina amanzi ngokulinganayo kwaye inciphise ukuvela kwe-shrinkgege.
Ukuphucula umgangatho wolondolozo: Ukugcinwa kwamanzi kakuhle kuqinisekisa ukuba isamente inamanzi aneleyo okuphendula ngokusemthethweni ngexesha lokulondolozwa kwangoko, ngaloo ndlela ukuphuculwa kwesamente.

2. Umsebenzi wokwakha

Ukuphuculwa kokusebenza kokwakha yenye indima ephambili ye-HPMC ekuthandeni. Ngokukodwa:
Ukuphuculwa kokuziphathi: I-HPMC inokunyusa iprimple yodaka, yenze kube lula ukusasazeka kunye nenqanaba ngexesha lokwakha, olubaluleke kakhulu kwizicelo ezinje ngokubekwa kwesahlulo kunye nomgangatho wodonga.
Isiphumo se-LPMMC: i-HPMC inokunciphisa ukungqubana kwangaphakathi kodaka, ukwenza isilayidi esihlekisayo ngakumbi kwizixhobo zokwakha, ukuphucula ukusebenza ngokukuko kunye nokunciphisa isixhobo sokwakha.
Ukuchasana: Xa ungqengqeleka: Xa i-Hing eQhelekileyo, i-HPMC inokuphucula ngokufanelekileyo ukunamathela kunye nokuchasana nokuntywila kodaka, ukuthintela udaka ukuba luhambekiwe.

I-3. Iipropathi ezinamathela

I-HPMC inika i-ceme yokufa kwesakhiwo esihleleleneyo, ebaluleke ngakumbi kwi-ARDS ethile ekhethekileyo (ezinjengee-tiles, ulungiso, njl njl.):
Ukuphucula ububi: ukongezwa kwe-HPMC kunokwenza amandla amakhulu okubulala phakathi kodaka kunye nomgangatho owona mgangatho, ngaloo ndlela kuphuculwe isiphumo sodaka.
Ukunciphisa ukuchithwa: Ipropathi yokunamathela ephucukileyo inokuthintela ungqimba olunamathela ekulibaziseni kwaye luphalaze xa lomile okanye phantsi koxinzelelo.
Yandisa amandla eShear: kwezinye iinkqubo ezifuna ukumelana noxinzelelo oluphezulu lwehenyukazi, i-HPMC inokuphucula ukumelana nodaka kodaka, ngaloo ndlela kuphucule uzinzo lwesakhiwo.

4. Ukuphuculwa kweemeko zokwakha

Isibonelelo sokuphucula iimeko zokwakha sesinye sezizathu zokuba i-HPMC ithandwa kakhulu, ngakumbi kwiimeko ezichaseneyo nendawo yokusingqongileyo, ukusetyenziswa kwe-HPMC kubaluleke kakhulu:
Izibonelelo kulwakhiwo lwamaqondo obushushu: i-HPMC inokunciphisa ukuvela kwamanzi kwiindawo eziphakamileyo zobushushu, ngaloo ndlela kudlulisa ixesha elivulekileyo, ngaloo ndlela kudlulise ixesha elivulekileyo kunye nexesha lokurhweba.
Izibonelelo kwimozulu ebandayo: Inceda ukugcina amanzi elubutyeni ngokukhawuleza, ngaloo ndlela uthintela ukuphendula okuneqondo lobushushu.

I-5. Ukuqiniswa okuphuculweyo

Sebenzisa i-HPMC kunokuphucula ukuqina kodaka lwesamente:
Ukuphucula ukungavisisani kwe-rack: ngokuphucula ukugcinwa kwamanzi ngohadi, i-HPMC kunciphisa ukunyibilika komhlaba kunye nokuqhekeka, ngokwenza oko kuphuculwe udaka lodaka.
Yandisa ukumelana nokunganyangekiyo kwimijikelezo ekhutshelweyo: i-HPMC inokunciphisa ukuvela kwe-rocks kubunjiwe obungubongo obubangelwe yimijikelezo-thaw kunye nokugcina ingqibelelo yezinto ezimqatha.
Ukunganyangeki kwe-Alkalinity: kwezinye iinkqubo ezizodwa, i-HPMC inokubonelela ngenqanaba elithile lokunganyangeki kwe-alkali ukukhusela ukhula lwesamente kwi-Alkali-Aggregreteate Dage.

I-6. Ukusebenza kwendalo

I-HPMC yindawo enobuhlobo bendalo engasayi kubanga kwenzakalisa kubasebenzi bokwakha kunye nokusingqongileyo:
Ayisiyo inetyhefu kwaye ayinabungozi: i-HPMC yi-ionic se-ionsulose i-ether enganetyhefu kwaye ayinabungozi emzimbeni womntu kunye nokusingqongileyo.
I-Degraded: i-HPMC i-biodegrades kwaye ayizukubangela ungcoliseko lwexesha elide kwindalo esingqongileyo.

7. Uqoqosho

Nangona ixabiso le-HPMC liphezulu, indalo yayo yezoqoqosho ibonakalisiwe ekuphuculeni ukusebenza kakuhle kunye nomgangatho wemveliso yokugqibela:
Ukuncitshiswa kwenqanaba lokusebenzela: Kuba i-HPMC inokuphucula ukusebenza ngokuphumelelayo kodaka, ukulungisa kwakhona okubangelwa ziingxaki zokusebenza kuncitshiswa kuncitshiswa, ke kuncitshiswa iindleko zizonke.
Gcina izixhobo: Udaka oluphuculweyo noludaka kunye neepropathi eziqhumayo zinciphisa inkunkuma ebonakalayo, zisebenzisa ukusetyenziswa kwe-HPMC ngakumbi uqoqosho.

Ukukhetha kunye nokusetyenziswa kwe-HPMC

Xa ukhetha i-HPMC, kuyimfuneko ukuqwalasela iiparamitha ezinje nge-viscofity, isidanga sokufaka, kunye nobukhulu becala. Ezi zinto zichaphazela ngqo intsebenzo ye-HPMC e-cemetion
I-Viskosity: I-viscofity ephezulu idla ngokuzisa ukugcinwa kwamanzi okungcono kunye nokusebenza ngokwakhiwa, kodwa kunokunciphisa umsebenzi osebenzayo. Ke ngoko, kuyimfuneko ukukhetha ibanga elifanelekileyo le-viscofity ngokwesicelo esithile.
Isidanga sokufakwa endaweni: Isidanga sokufaka sichaphazela ukonakala kunye nokusebenza kwe-HPMC. Inqanaba elifanelekileyo lokufaka endaweni inokuqinisekisa ukusasazwa ngokufanayo kunye nomsebenzi we-HPMC elulalweni.
Ubungakanani bentsumpa: Ubungakanani be-chieer ye-ficter inokwenza i-HPMC kulula ukuxuba ngokulinganayo nodaka kunye nokuphucula isiphumo sayo.

Ukusetyenziswa kwe-ILPMP ekumgangatho ophezulu we-HPMC e-Cemetion Orcen kunceda ekuphuculeni ukugcinwa kwamanzi, ukusebenza, ukusebenza kokwakha, ukusebenza kokusebenza, ukuqina kodaka, ngelixa kuphucula iimeko zokwakha kunye noqoqosho. Ukusetyenziswa kwayo kunokunciphisa ngokufanelekileyo iingxaki ezinjengokuqhekeka nokuwa kodaka, kwangenisa ubomi benkonzo yezixhobo, kwaye unike isisombululo esinobuhlobo esikude. Kulwakhiwo lwale mihla, i-HPMC iye yaba lusongelwe, ukwenza igalelo elibalulekileyo ekuphuculeni intsebenzo yezinto zokwakha kunye nokuqinisekisa umgangatho wokwakha.
