Udaka lwegypsum oludityanisiweyo lweHPMC:

3.1.Inkqubo yokwenziwa kwemveliso:

Ukuveliswa kwegypsum ebotshelelweyo ye-HPMC kubandakanya ukufakwa kwe-hydroxypropyl methylcellulose kwi-matrix yegypsum.Oku kufezekiswa ngenkqubo yokuxuba elawulwa ngononophelo, ukuqinisekisa ukuba iinqununu ze-HPMC zisasazwa ngokulinganayo ngaphakathi kwe-gypsum matrix.Isiphumo sisixhobo esiyintlanganisela esifumana inzuzo ye-HPMC kunye negypsum.

3.2.Iimpawu ze-HPMC ebotshelelwe kwigypsum:

Indibaniselwano ye-HPMC kunye negypsum inika iipropati ezidibeneyo ezidibeneyo.Oku kubandakanya ukusebenza okuphuculweyo, ukunamathela okuphuculweyo, ixesha lokumisela elongeziweyo kunye nokuqina okwandisiweyo.Izithako ze-HPMC zinceda ukugcina ukufuma, zithintele ukomisa kwangaphambi kwexesha kwaye ziqinisekise ukugqiba okungaguqukiyo nokugudileyo.

Ukusetyenziswa kwegypsum ebontshwe yiHPMC:

4.1.Udonga luyagqibezela:

Udaka lwegypsum oludityanisiweyo lwe-HPMC luqhele ukusetyenziswa njengesixhobo sokugquma eludongeni.Ukusebenza kwayo okuphuculweyo kwenza kube lula ukuyifaka kunye nokugqiba, okukhokelela kwindawo egudileyo kunye neyobuhle.Ixesha lokumisela elongeziweyo elinikezwe yi-HPMC liqinisekisa ukuba umtyabi unexesha elaneleyo lokufikelela ukugqiba okufunayo.

4.2.Isimbo sokuhombisa:

I-composite isetyenziselwa ukwenza ukubumba okuhombisa kunye nezinto zokwakha.Ukuguquguquka kwayo kuvumela uyilo oluntsonkothileyo kunye neenkcukacha, ukubonelela abayili bezakhiwo kunye nabaqulunqi ngeendlela ezininzi zokuyila.

4.3.Ukulungisa kunye nokubuyisela:

Udaka oludityanisiweyo lwe-HPMC lulungele ukulungiswa nokubuyiselwa kweeprojekthi apho ukuhambelana kwayo nemigangatho ekhoyo yodaka kunye nokuqina okwandisiweyo kudlala indima ebalulekileyo.Ivumela ukulungiswa okungenamthungo kwaye iqinisekisa ixesha elide lokulungiswa kwendawo.

Izinto eziluncedo kwi-HPMC ebotshelelwe kwigypsum:

5.1.Phucula ukuqhubekeka:

Ukongezwa kwe-HPMC kwandisa ukusebenza kwe-gypsum plaster, ukwenza isicelo kunye nokugqiba kube lula.Oku kunenzuzo ngakumbi kubatyabeki njengoko kuvumela ulawulo olukhulu kunye nokuchaneka ngexesha lokutyabeka.

5.2.Yandisa ixesha lokuqinisa:

Ixesha lokumisela elongeziweyo elinikezelwe yi-HPMC liqinisekisa ukuba umtyabi unexesha elaneleyo lokugqiba isicelo kunye nokufezekisa umphumo oyifunayo.Oku kunenzuzo kwiiprojekthi ezinkulu okanye apho ukulibaziseka kwexesha lokumisela kufuneka.

5.3.Yandisa ukunamathela:

I-HPMC inceda ukuphucula ukunamathela, okubangela ukuba kubekho iqhina elinamandla phakathi kodaka kunye ne-substrate.Le propati ibaluleke kakhulu kwisigxina kunye nobude bomphezulu ogqityiweyo.

5.4.Ugcino lwamanzi:

Ukukwazi ukubamba amanzi kwe-HPMC kuthintela ukomiswa kwangaphambi kwexesha kodaka, okukhokelela kwisiphelo esingaguqukiyo, esigudileyo.Oku kubaluleke ngakumbi kwimozulu eyomileyo okanye xa usebenza kwiindawo ezinkulu, apho ukugcina amanqanaba okufuma angaguquguqukiyo kunokuba ngumngeni.
