Iimpawu eziphambili kunye nokusetyenziswa kwe-hydroxypropyl methylcelcelgalose

I-HydroxypropylMethylcelcelcelcelcelcelcel Ihambelana nothotho lwezinto zekhemikhali ngokuguqula i-sellyulose yendalo, icandelo eliphambili leendonga zeseli zesityalo. I-HPMC ekhuphisiweyo ineseti eyahlukileyo yepropathi eyenza ukuba ibe lixabisekile kumashishini.

1. Ubume kunye nokuqulunqwa:

I-HPMC isuselwa kwisellulose, equka ukuphinda iphinda iphinde iphinde iphinde idityaniswe yi-β-1,4-Glycosidic Bonds. Ngokuguqulwa kwamachiza, i-hydroxypropy kunye namaqela e-AFCHYy aziswa kwi-selsulose backbone. Inqanaba lokufakwa endaweni (DS) ye-hydroxypropy kunye namaqela e-AFGISY inokwahluka, ikhokelela kumabakala ahlukeneyo e-HPMC enepropathi eyahlukeneyo.

Isakhiwo sekhemikhali se-HPMC sikunika isolula kunye nokwenza ubuchule bokwenza ubuchule, kokwenza kube luncedo kuluhlu olubanzi lwezicelo kumashishini ahlukeneyo.

I-2. Ukungasebenzi kunye neepropathi ze-rheoology:

Enye yeepropathi ezibonakalayo ze-HPMC kukomeleza kwayo emanzini, kusenza i-polymer enyibilikayo yamanzi. I-HPMC icacisa isisombululo esicacileyo nesivisisayo xa sichithwe emanzini, kwaye iipropathi zayo ze-ROOOOLOTE zinokulungiswa ngokutshintsha ubunzima bemolekyuli kunye nenqanaba lokufaka endaweni. Olu ncedo lukhuni kunye ne-raheelogy yenza i-HPMC efanelekileyo kwizicelo ezahlukeneyo.

3. Ukusebenza kwefilimu:

I-HPMC inepropathi egqwesileyo yefilimu kwaye inokwenza iifilimu eziguquguqukayo xa i-polymer ichithwe emanzini. Le propati ifumana isicelo kumashishini okutya kunye nokutya kwiitafile zokubhabha, ukudibanisa iincasa kunye nokubonelela ngeepropathi zomqobo kwiifilimu ezidliwayo.

4. Izicelo zonyango:

I-HPMC isetyenziswe ngokubanzi kumzi-mveliso wamayeza ngenxa yepropathi yamayeza ahlukeneyo. Isetyenziselwa ukwenziwa kweefomu zecwecwe njenge-binder, intsholongwane, iarhente yefilimu yefilimu kunye ne-arhente yokukhupha i-Refled. Amandla ePolymer ukulawula ukukhululwa kweziyobisi kwaye aphucule uzinzo lwamayeza enza ukuba ifumane isithako esibalulekileyo ekuvelisweni kweefom ezahlukeneyo zedosi.

5. Ishishini lokwakha:

Kumzi-mveliso wokwakha, i-HPMC isetyenziswa njengearhente yokuthambisa, iarhente yokugcina amanzi kunye nokuphucula imisebenzi esekwe kwimo yesamente efana nokufa, i-griuts kunye neeplaters. Iipropathi zayo zezahlulo zobukumkani zinceda ukuphucula ukusebenza, ukuxhathisa kuka-SAG kunye nokunamathela, kuyenza i-Indenti yeqhosha lezinto zokwakha.

I-6. Ukutya kunye ne-cosmetics:

Kwishishini lokutya, i-HPMC isetyenziswa njenge-thi chuker, i-enulssifier, kunye nokuzinza kwiimveliso ezahlukeneyo, kubandakanya iisosi, izimilo, kunye neemveliso zobisi. Isimo sayo esingengobutyhefu kunye nokukwazi ukwenza iigles ezicacileyo zenza ilungele ukusetyenziswa kwezicelo zokutya.

Ngokukwanjalo, kwiShishini leCosmetics, i-HPMC isetyenziswa ekuqulunqweni njengekhrim, i-lotions, kunye ne-shampoos ngenxa yokutyibilika kwayo, ukuzinzisa, kunye nokuzinzisa iipropathi. Inegalelo kumgaqo, i-viscosity kunye nokuzinza kwezinto ze-cosmetics.

I-7. Iipeyinti kunye neengubo:

I-HPMC isetyenziswa njenge-thickener kunye ne-ratheology modifier kwiipeyinti ezisekwe emanzini kunye neengubo. Iphucula iipropathi zesicelo sookhokho, ezinjengokuthi upeyinti kunye nokungaxhathisi i-splash, ngelixa kuphucula ukusebenza kwentsebenzo.

8. Ukunamathela:

Kwimidlalo yokunamathela, i-HPMC isebenza njengearhente ye-thickener kunye nendawo yokugcina amanzi. Ukukwazi kwayo ukulawula i-viscofity kunye nokuphucula ubumbethe benza ukuba ibe lixabisekile ekuvelisweni kwemizi-mveliso eyahlukeneyo yemizi-mveliso, kubandakanya ukusebenzela okwenziwe ngomthi kunye nephepha elinamaphepha.

I-9. Inkqubo elawulwayo:

Ukukhutshwa okulawulwa kwezithako ezisebenzayo kubalulekile kumashishini amaninzi, kubandakanya amayeza kunye nezoLimo. I-HPMC ihlala isetyenziselwa ukuyila iinkqubo zokukhutshwa kolawulo ngenxa yokwazi ukwenza i-matrix elawula izinga lokukhupha izinto ezinolwazi ngexesha.

I-10. Izicelo ze-biomeds:

Kwimimandla ye-bionedicine kunye nenjineli yezicubu, i-HPMC iphononongiwe ngenxa ye-biompatiby yayo kunye nokukwazi ukwenza i-hydrogels. Ezi hydrogels zingasetyenziselwa ukuhanjiswa kweziyobisi, ukuphiliswa kwenxeba, kunye nezixhobo zokugcina izicubu.

11. Iimpawu zoKhuselo lokusiNgqongileyo:

I-HPMC ithathwa njengendawo enobuhlobo ngokwendalo njengoko ifumaneka kwizibonelelo ezihlaziyiweyo kwaye inokwenzeka. Ukusetyenziswa kwayo kwizicelo ezahlukeneyo kuhambelana nemfuno ekhulayo yezixhobo ezizinzileyo nezisingqongileyo.

12. Imiceli mngeni kunye nokuqwalaselwa:

Nangona i-HPMC isetyenziswa, imiceli mngeni emininzi, kubandakanya ubuntununtunu obunobushushu, echaphazela iipropathi zayo. Ukongeza, inkqubo yokuhlengahlengiswa kunye nekhemikhali yeselselose ifuna ukuqwalaselwa ngononophelo kwimbono yokusingqongileyo kunye nokuzinzileyo.

13. Ukuthobela umthetho:

Njengalo nayiphi na into esetyenziswayo kwiindawo zamayeza, ukutya kunye nezinye iimveliso zabathengi, kubalulekile ukuba kulandelwe iiarhente zolawulo ziyalandelwa. I-HPMC ngokubanzi idibana neemfuno zolawulo, kodwa abavelisi kufuneka baqinisekise ukuthotyelwa kwezikhokelo ezithile zesicelo ngasinye.

ukuququmbela:

I-HydroxyPOpyMmethylcelcelcelcelcelcelcel Indibaniselwano yayo eyahlukileyo ye-solidaity, iipropathi ezenziweyo zefilimu kunye nolawulo lwe-Rheeology yenza ukuba ingabaluleki kwiindawo zamayeza, ukwakhiwa, ukutya, izinto ezinamachaphaza, amachaphaza, amachaphaza, amachaphaza, amachaphaza, amachaphaza, amachaphaza, amachaphaza. Njengoko amashishini aqhubeka nokufuna izisombululo ezizinzileyo nezisebenzayo, i-HPMC inokwenzeka ukuba ihlale ingumdlali ophambili kwiziko ezahlukeneyo zemveliso. Ngaphandle kwemiceli mngeni, uphando oluqhubekayo kunye nenkqubela phambili kwi-chellulose chemistry inokwandisa ngakumbi izicelo kunye nokuphucula ukusebenza kwe-HPMC kwixa elizayo.
