Ungawubona njani umgangatho we-HPMC?

Ukuchonga umgangatho weHydroxypropyl methyl seluplose (hpmc)kubandakanya ukuthathela ingqalelo izinto ezininzi eziphambili. I-HPMC isetyenziswa kumashishini ahlukeneyo, kubandakanya nolwakhiwo, amayeza, ukutya, kunye neyeza, kwaye umgangatho wayo unokwenza ifuthe intsebenzo yemveliso yokuphela. Nazi ezinye izinto ezibalulekileyo ekufuneka ziqwalaselwe xa kuvavanywa umgangatho we-HPMC:

1. Inqanaba lokufakwa endaweni (DS):

Inqanaba lokufaka endaweni libhekisa kwinani le-hydroxypropy ye-hydroxypropy kunye namaqela e-methyl kwiyunithi ye-anhhydroglucose kwimo yeselselose. Iphembelela ngokuthe ngqo iipropathi ze-HPMC. Iinqobo eziphakamileyo ze-DS ngokubanzi zikhokelela ekunyukeni kokungasebenzi kwamanzi kunye neepropathi zeRheology. Abavelisi bacacisa i-DS yeemveliso zabo ze-HPMC.

2. Ubunzima bemolekyuli:

Ubunzima be-MPMC ye-HPMC yiparamitha ebalulekileyo echaphazela intsebenzo yayo. Ii-moleks zemolekyuli eziphezulu zihlala zinxulunyaniswa neepropathi ezingcono zefilimu kunye nokunyuka kwe-viscosity. Ukuhanjiswa kwesisindo kwe-molekyuli kufuneka kungahambelani kuluhlu oluchaziweyo lwemveliso enikiweyo ye-HPMC.

I-3. UVIKILE:

I-HPMC iyafumaneka kumabanga ahlukeneyo okufakwa, kwaye ukhetho lwe-viscofity luxhomekeke kwisicelo esithile. I-Viscosity yipharamitha ebaluleke kakhulu ekuphembeleleni ukuhamba nokuziphatha kwezinto zezisombululo okanye ukusasazeka okune-HPMC. I-vickosity ihlala ilinganiswe kufuna iindlela ezisemgangathweni, kwaye abavelisi babonelela ngenkcazo yokufakwa kweemveliso zabo kwiimveliso zabo.

I-4. Ubungakanani bentsumpa:

Ubungakanani be-HPMC bunokuchaphazela ukusasazeka kunye neepropathi zokuchitha. Ubungakanani bamanqaku amancinci ngokubanzi bukhokelela ekusasazeni okungcono emanzini okanye kwezinye izinyibilikisi. Abavelisi banokubonelela ngolwazi malunga nobungakanani be-suricle yokusasazwa kweemveliso zabo ze-HPMMC.

I-5. Ukucoceka nokungcola:

I-HPMC ekumgangatho ophezulu i-HPMC kufuneka ibe nenqanaba eliphezulu lokucoceka, ngokungcoliseka okuncinci. Ubukho bezinto ezingcolileyo okanye ezingasetyenziswanga zinokwenza ifuthe elibi ukusebenza kwe-HPMC kwizicelo ezahlukeneyo. Abavelisi babonelela ngolwazi ngobunyulu beemveliso zabo ze-HPMC.

6. Iqondo lokushisa:

Amanye amabakala e-HPMC abonisa indlela yokuziphatha ye-HRMC, akha iigesi kumaqondo obushushu aphakamileyo. Iqondo lokushisa yiparamenti ebalulekileyo, ngakumbi kwizicelo apho utshintsho lobushushu lunokwenzeka khona ngexesha lokuqhutywa. Iipropathi zokuhambisa kufuneka zihambelane kwaye kuluhlu oluchaziweyo.

I-7. Ukunyibilikisa:

I-HPMC yaziwa ngokuba ziipropathi zalo ezinyibilikayo zamanzi, kodwa ireyithi kunye nobungakanani bonqulo-buzo bungahluka. I-HPMP ekumgangatho ophezulu ye-HPMC kufuneka inyibilike ngokulula emanzini okanye ezinye iinyikima ezichaziweyo phantsi kweemeko ezifanelekileyo. Ukungasebenzi kunokuphenjelelwa yi-DS kunye nezinye izinto.

8. IPROPRETERE APRORTER:

Umgangatho we-HPMC uhlala uvavanywa ngokusekwe kwintsebenzo yayo kwizicelo ezithile. Umzekelo:

• Kwizicelo zokwakha, ezinje ngodaka okanye ii-eifs, izinto ezinje ngokuzigcina amanzi, ukusebenza kwamanzi, ukusebenza, kunye nokunamathela.
• Kwizicelo zamachiza, ukukhululwa kwamachiza kunye neepropathi zokudibana kwetafile kubalulekile.
• Kwisicelo sokutya kunye nezicelo zokusebenza, imisebenzi efana nokuthambisa kunye nokuzinzisayo sisitshixo.

9. Udumo lomvelisi:

Ukukhetha i-HPMC kubavelisi abadumileyo kubalulekile ekuqinisekiseni umgangatho. Abavelisi abasekwe ngembali yokuvelisa izinto ezikumgangatho ophezulu weselselose zinokubonelela ngeemveliso ezinokuthenjwa nezingaguqukiyo.

I-10. Uvavanyo kunye nesiqinisekiso:

Uvavanyo lwelebhu kunye nesiqinisekiso ngemigangatho yemigangatho eyamkelweyo inokubonelela ngoqinisekiso ongezelelweyo lomgangatho we-HPMC. Abavelisi banokubonelela ngezatifikethi zohlalutyo okanye ukuthotyelwa kwemigangatho ethile.

ISIQINISEKISO:

Ukuvavanya umgangatho we-HPMC kubandakanya ukudityaniswa kokuvavanya iipropathi zayo zomzimba kunye nekhemikhali, ukuqonda iimfuno zesicelo, kunye nokuqwalaselwa kwegama lomvelisi. Kubalulekile ukubhekisa kwinkcazo yemveliso, izatifikethi zohlalutyo, kunye nezikhokelo ezinikezelweyo ezibonelelwa ngumenzi wolwazi oluchanekileyo kumgangatho wemveliso ethile ye-HPMC.
