• Uhlengahlengiso lweFomu: Zama iindlela ezahlukeneyo zokuxuba izithako ukuze ufumane ibhalansi efanelekileyo yezithako ezibonelela ngokusebenza kakuhle.

3. Ixesha Lokunyanga Elicothayo

Ingxaki: Ixesha elicothayo lokucocwa linokulibazisa iinkqubo zokwakha ezilandelayo, nto leyo enciphisa ukusebenza kakuhle kwayo iyonke.

Iimbangela:

• Ukugcinwa kwamanzi ngokugqithisileyo
• Uxinzelelo oluphezulu lwe-HPMC

Izisombululo:

• Umxholo wamanzi: Nciphisa umlinganiselo wamanzi asetyenziswa kumxube we-putty ukuze ukhawulezise ukunyibilika. Qinisekisa ukuba umthamo wamanzi ukwinqanaba elicetyiswayo lokusetyenziswa kwakho.
• Uxinaniso olulinganiselayo lwe-HPMC: Yehlisa uxinzelelo lwe-HPMC ukuba iphezulu kakhulu. Nangona i-HPMC iphucula ukugcinwa kwamanzi, ukuba ininzi kakhulu kunokwandisa ixesha lokunyanga.

4. Ukuqhekeka komphezulu

Ingxaki: Ukuqhekeka komphezulu kuyawuphazamisa ubuhle kunye nokuthembeka komaleko we-putty.

Iimbangela:

• Ukomisa ngokukhawuleza
• Ubukhulu bokusetyenziswa obungalunganga
• Ibhalansi embi yefomyula

Izisombululo:

• Ukomisa okulawulwayo: Kuphephe ukomisa ngokukhawuleza ngokulawula iimeko zokusingqongileyo. Sebenzisa izigqubuthelo zokukhusela okanye ulawule ubushushu kunye nokufuma kwemozulu.
• Ubukhulu besicelo: Faka i-putty kwiileya ezincinci (1-2 mm) ukuthintela ukuqhekeka. Vumela umaleko ngamnye wome ngokupheleleyo ngaphambi kokufaka olandelayo.
• Ibhalansi yokuQulunqa: Lungisa indlela yokwenza izinto ukuze ifake izongezo eziguquguqukayo ezinokunceda ekunciphiseni uxinzelelo lomphezulu kunye nokuthintela ukuqhekeka.

5. Ukunamathela okuphantsi

Ingxaki: Ukunamathela okuncinci kunokubangela ukuba i-putty ikrazuke, nto leyo enciphisa ukuqina kwesiphelo.
