I-HPMC idlala yiphi indima kwindawo yokubulala?

I-HPMC (Hydroxypropyl methylcelcelcelsulose)yindawo esetyenziswayo esetyenziswa yiPolymer esetyenziswe ngokubanzi ebaleni lababulala. Idlala indima ebalulekileyo kwimiba emininzi yezifo.

I-1. Umsebenzi we-arhente yokusebenza
I-HPMC yi-thickener efanelekileyo enokuphucula kakhulu i-viscofity kunye nokuzinza kwemihlambi. Ulwakhiwo lwayo lwe-molecular lune-hydrophicicity kunye nemixokelelwane ye-Polysactoide, kwaye inokwenza isisombululo se-colloidal ye-colloidal kumanzi okanye izinyibilikisi eziphilayo. Olu phawu lunokuthintela ngokufanelekileyo ukuthambelela ekuzilibaziseni okanye ukuhlalisa ngexesha lokugcina kunye nokusetyenziswa, ngaloo ndlela kuqinisekisa ukufana kwembeko.

2. Ukuphucula ukusebenza kwe-adhesion
I-HPMC ineepropathi ezigqwesileyo kwaye inokuphucula kakhulu ukunamathela kubunamatheko. Emva kokudityaniswa komphezulu wezixhobo ze-subtate, iimolekyuli ze-HPMC zinokungena kwi-pores entle phezu kwendawo yokwandisa amandla kwaye ilungele izixhobo ezahlukeneyo njengephepha, ifibre, iinkuni kunye ne-ceramics.

I-3. Ipropathi yokwakha ifilimu
I-HPMCInepropathi ebalaseleyo yefilimu kwaye inokwakha ngokukhawuleza iyunifom kunye nefilimu eqhubekayo emva kokuqeqesha. Le filimu inobunzima obuhle kunye nobunzima kwaye inokubonelela ngomaleko ongezelelweyo wokukhusela imbeko, ukuphucula ukuqina kunye nokungaphantsi kwebhondi. Ukongeza, ifilimu inciphisa ifuthe leemeko zangaphandle, ezinje ngomswakama okanye utshintsho lobushushu, ukusebenza kweqondo lobushushu.

4. Ukugcinwa kwamanzi
I-HPMCUnamanzi agqwesileyo amanzi afanelekileyo kwaye unokukhawulela umswakama kwi-adhetive ukukhulisa ukulahleka kwamanzi okugqithisileyo. Eli nqaku libaluleke ngokukodwa kwizinto ezisekwe emanzini kunye nezixhobo ezisekwe emanzini, ezinokwandisa ixesha lokuvula, ziqhuba lula ukwakhiwa, kwaye zithintele ukuntywila kwamanzi okubangelwa kukukhululeka kwamanzi.

I-5. Isiphumo se-stabilizer
I-HPMC inokuphucula kakhulu uzinzo lwenkqubo yokunamathela, thintela ukuhlawula okanye ukwahluka kweendawo eziqinileyo, kunye nokugcina ukufana kwemveliso. Amaqela asebenzayo kwi-molecular thein anokusebenza ngokulinganayo namanye amacandelo ukuphucula uzinzo kunye nokusebenza kwefomula.

I-6. Ubuhlobo bokusingqongileyo
I-HPMC yimveliso efunyenwe ngokutshintsha kweekhemikhali kweselutase yendalo. Ayisiyo inetyhefu, engenabungozi kwaye ingonakali. Ukusetyenziswa kwayo ezi-2 ezihambelana neemfuno zoKhuselo lweNdalo esiNgqongileyo kwaye unedini elibalulekileyo ngakumbi kulwakhiwo, ukupakisha kunye namashishini okutya.

7. Lungisa i-RHOOOLORT
Iipropathi ze-ratheorical ezikhethekileyo ze-HPMC kwisisombululo (ezinjengokuthambisa ishera) Yenza ukubambelela ukuba nembeko ukuba nepropathi efanelekileyo yokwakha ngexesha lesicelo. Uhlobo lwayo luphumelela phantsi kweemeko eziphakamileyo ze-Shear, zenza kube lula ukupeyinta, ukutshiza okanye ukutshiza, ngelixa ukuviwa kwayo kuphinda kuphindwe phantsi kwempahla ye-Shear.

Iindawo zesicelo
Njengecandelo elibalulekileyo lababulala, i-HPMC isetyenziswa ngokubanzi kwezi nkalo zilandelayo:

Umzi-mveliso wokwakha: njenge-TIle Adhestive, i-pople powder, udaka olwahlukileyo, elisetyenziselwa ukuphucula ukusebenza nokwakha amandla.
Ukuphuculwa komthi
Ipapermang kunye nokuprinta: isetyenziselwa iphepha elibandayo lokuphucula ubuhle kunye ne-adhesion.
Isikhumba kunye nesikhumba: isetyenziselwa ukwenziwa kwe-fiber kunye nesikhumba.

I-HPMCIdlala iindima ezininzi kwiindawo ezinamachaphaza anjengokutyibilika, ukugcinwa kwamanzi, ukuzinza, ukuphuculwa komthendeleko kunye nokuqulunqwa kwefilimu. Ikwanazo izibonelelo zokusikhusela kwendalo esingqongileyo kunye ne-geology ehlengahlengisiweyo. Ezi ndawo zenza ukuba zibe necandelo elibonakalayo kunye elibalulekileyo kwifomu elinamathela, zibonelela ngenkxaso ebalulekileyo ekuphuculeni ukusebenza kwemveliso kunye nokuhlangabezana neemfuno ezahlukeneyo.
