I-HPMC inyula njani i-athedhes yodaka?

I-Hydroxypropyl Methylcelceltulose ye-Chemical Scocimils esetyenziswa kakhulu kwizixhobo zokwakha, ngakumbi kwifomula yokufakelwa. Iphucula i-addion yodaka ngeendlela ezahlukeneyo.

1. Phucula ukusebenza kwentsebenzo yokwakha
I-HPMC inogcino oluhle kakhulu lwamanzi kunye ne-tyhurity, enokuphucula kakhulu ukusebenza kodaka. Ukuphuculwa kwentsebenzo kwenza ukuba udaka lusetyenziswe lula kumphezulu wokuthambisa, ukunciphisa iingxaki zokunamathela ezibangelwa zizilwanyana ezingenazilwanyana ngexesha lenkqubo yokwakha.

Ukugcinwa kwamanzi: i-HPMC inokuqhelisela ixesha lokuphuma kwamanzi elubuthelweni, ukuqinisekisa ukuba udaka lunexesha elaneleyo lokugqibezela isamente emva kwesicelo. Olu hlaselo lwe-hydration olwaneleyo luyanceda ekwenzeni uxinzelelo oluphezulu, ijeli eyomeleleyo egqunywe ngokuqinileyo kumphezulu we-subtate.
Isiphumo soLuhlu: i-HPMC yenza ukuba udaka lunemilo yolwelo kunye neplastiki, kokwenza kube lula ukufaka kunye nokuqulunqwa, emva koko ukufezekisa indawo ephakathi kodaka kunye nokuphucula ubumbisi.

2. Phucula ubumbano lodaka
I-HPMC inokuphucula kakhulu ubumbano lodaka kwaye uthintele ukuqhekeza okanye ukuwa ngexesha lokwakha kunye nokomisa.

I-HPMC iyenza imeko yenethiwekhi eguqukayo kudaka ukuba idibanise ngokuqinileyo amacandelo kwaye ukunciphisa ukuvela kwamancinci amanzi ngaphakathi kodaka.
Ukuphuculwa kokunamathela ngokungathanga ngokungathanga ngqo kuphucula ukunamathela kodaka kubambeko, kuba ubumbano olwaneleyo unokukhokelela ekuqhekekeni komlinganiso.

I-3. Yenza ikhowudi yokujonga ulwazi
Ukunamathela kodaka kunxulumene ngokusondeleyo nefuthe kumphezulu we-subsest. Isakhiwo esikhethekileyo se-molecular se-HPMC sidlala indima yokungena kunye nokungena kwi-interface:

Ukungqinelana: Emva kokuba i-HPMC ichithwe, iya kuvelisa isisombululo se-colloidal kunye nokungena kwi-capillary pores kumphezulu we-substing kumgangatho wokutshixa kunye nokuphucula ubunamatheko.
Isinxibelelanisi sokukhangela: I-HPMC inciphisa ukungqubana komphezulu wodaka lodaka, kuyenza kube lula ukusasazeka kumphezulu we-substrate kwaye yenze iyunifomu kunye nonxibelelwano olusondeleyo nonxibelelwano olusondeleyo.

4. Ukucutha i-shrinkges eyomileyo
Ingxaki ye-shrinking eyomileyo yingxaki eqhelekileyo echaphazela ububi bodaka, ngakumbi kwiimeko ezomileyo. I-HPMC inciphisa ngokufanelekileyo ukuqhekeka kwe-shrinking shrinking kwezi ndlela zilandelayo:

Ukugcinwa kwamanzi i-HPMC kwenza ukuba ukusasazwa kwamanzi kodaka ngakumbi nangona kunjalo kwinkqubo yokukhula, ukunciphisa uxinzelelo loxinzelelo olubangelwa lomile.
Inkqubo yokugcina amanzi ikwanciphisa iqondo elomileyo lokutshiswa kodaka kumanqanaba okuqala okunyanga, ngaloo ndlela kunciphisa umngcipheko wokuqulunqa kwe-rack kunye nokuphucula ingqibelelo kunye nokuqina kwengqibelelo.

5. Phucula amandla eShear yodaka
I-Adhesion ilunge kakhulu kumandla e-Shear. Ubume benethiwekhi ye-viscoelastic eyenziweyo yi-HPMC kwi-vissec kunceda ukuphucula amandla odaka kodaka, ngaloo ndlela iphucula imihlambi.

Ulwakhiwo lwenethiwekhi lunokusasaza uxinzelelo xa liphantsi kwaye liphephe ukungaphumeleli okubangelwa kukugxila koxinzelelo lwasekhaya.
I-HPMC inokuphucula ukuqaqanjelwa kunye nokunganyangwa kodaka, ivumela ukuba ilungelelanise ngcono kwiingxaki ezincinci zebhulukhwe.

I-6. Phucula ukuqina kodaka
Ukuqina yinto ephambili kwi-Adhee-Adhesion yexesha elide. I-HPMC iphucula amandla ayo okumelana neempembelelo zokusingqongileyo (njengamanzi, ubushushu, imitha ye-ultraviolet, njl.njl) ngokuguqula udaka.

I-HPMC inokuphucula ukuchasana nokunganyangeki komkhenkce kwaye kuthintele umaleko wokubiyela ukuwela ngenxa yemijikelezo ye-freeze-thaw.
Ngaphantsi kweemeko zobushushu obuphezulu, ukugcinwa kwamanzi e-HPMC kunye neziphumo zokugcina izinto zinokuthintela ngokufanelekileyo udaka ekuphulukaneni nobombiso ngenxa yokulahleka kwamanzi kakhulu.

I-7. Ukuziqhelanisa nokuziqhelanisa nabantu abahlukeneyo
I-HPMC inokuhlengahlengisa ifomula yokutsala ukwenza ukuba ilungele iintlobo ezahlukeneyo zezinto eziphantsi (ezinje ngekhonkrithi, iBhodi yeGypsim, njl. Njl.). Ngokwenza into eqinisekileyo yexabiso kunye ne-viscosity ye-HPMC, udaka lungangcono luhlangabezane neemfuno zokuncamathela.

I-HPMC iphucula ngokucacileyo ukunamathela kodaka ngokuphucula izinto ezifana nokusebenza kuka-Piards, ukuhlangana, ukusebenza kwe-interface, ukunyangwa kunye nokuqina kunye nokuqina kunye nokuqina kunye nokuqina kunye nokuqina kunye nokuqina kunye nokuqina kunye nokuqina. Ukusetyenziswa ngokuchanekileyo kwe-HPMC akunakuphucula umgangatho wokwakha isiphithiphi, kodwa kukwandise ubomi bayo benkonzo, udlale indima engenakufikelelwa kwaye ibaluleke kakhulu kwiiprojekthi zokwakha.
