Isizathu sokuba i-hydroxypropyl methylcellulose ixutywe ngakumbi kwi-putty powder

Isizathu sokuba kuthenii-hydroxypropyl methylcelluloseingaba ixutywe ngakumbi nangakumbi kwi-putty powder?

Xa umgubo we-putty uveliswa kwaye usetyenziswa, kuza kubakho iingxaki ezahlukeneyo. Emva kokuba umgubo we-putty uxutywe namanzi kwaye uxutywe nge-drill yombane, i-putty iya kuba ncinci njengoko ixutywa, kwaye imeko yokwahlulwa kwamanzi iya kuba yingozi kakhulu. Unobangela wale ngxaki yi-putty. I-Hydroxypropyl methylcellulose yongezwa kumgubo.

1. I-viscosity ye-hydroxypropyl methylcellulose ayifanelekanga, i-viscosity iphantsi kakhulu, kwaye isiphumo sokumiswa asanele. Ngeli xesha, imeko yokwahlulwa kwamanzi iya kuba yingozi, kwaye isiphumo sokumiswa okufanayo asinakubonakaliswa.

2. I-hydroxypropyl methylcellulose egcina amanzi yongezwa kumgubo we-putty, onefuthe elihle kakhulu lokugcina amanzi. Xa i-putty inyibilika emanzini, ivala amanzi amaninzi. Ngeli xesha, amanzi amaninzi afakwa emanzini. Iqhuma, xa lixutywa, amanzi amaninzi ayahlulwa, ngoko ke kukho ingxaki yokuba okukhona uxuba ngakumbi, kokukhona lincipha; le yingxaki eqhelekileyo, kwaye abantu abaninzi baye badibana nengxaki enjalo. Ubungakanani be-cellulose obongeziweyo okanye ukufuma okongeziweyo kunokunciphisa ngokufanelekileyo.

3. I-hydroxypropyl methylcelluloseinolwalamano oluthile nesakhiwo sayo. Ine-thixotropy, ngoko ke yonke i-coating ine-thixotropy ethile emva kokufaka i-cellulose, ngoko ke xa i-putty ishukunyiswa ngokukhawuleza, isakhiwo sayo siphela Sisasazekile, sibonakala sincinci ngakumbi nangakumbi, kodwa xa singashukumi, sibuyela kwimeko yaso kancinci kancinci.
