Indima ye-hydroxypropyl methylcellulose kwi-putty

Indima ye-hydroxypropyl methylcellulose kwi-putty

Ukususela ekuqineni, ukugcinwa kwamanzi kunye nokwakhiwa kwemisebenzi emithathu.

Ukuqina: I-Cellulose ingenziwa ibe nkulu ukuze imiswe, igcine isisombululo sifana kwaye sihambelana, kwaye imelane nokugoba. Ukugcinwa kwamanzi: Yenza umgubo we-putty wome kancinci, kwaye uncede ukusabela kwe-calcium yomlotha phantsi kwesenzo samanzi. Ulwakhiwo: I-Cellulose inefuthe lokuthambisa, elinokwenza umgubo we-putty usebenze kakuhle. I-Hydroxypropyl methylcellulose ayithathi nxaxheba kuyo nayiphi na i-reaction yamakhemikhali kwaye idlala indima encedisayo kuphela. Umgubo we-putty wongezwa ngamanzi ukuze udonga luhlangane, oluyi-reaction yamakhemikhali, kuba kukho ukwakheka kwento entsha ye-calcium carbonate. Izinto eziphambili ze-ash calcium powder zezi: umxube we-calcium hydroxide Ca(OH)2, i-calcium oxide CaO kunye nenani elincinci le-calcium carbonate CaCO3. I-ash calcium yenza i-calcium carbonate phantsi kwesenzo se-CO2 emanzini nasemoyeni, ngelixa i-hydroxypropyl methyl I-Cellulose igcina amanzi kwaye inceda ukusabela okungcono kwe-calcium yomlotha, yona ngokwayo engathathi nxaxheba kuyo nayiphi na i-reaction.

Siqala ngokuhlalutya izizathu zokuwa komgubo we-putty kwizinto ezikrwada ze-putty: umgubo we-ash calcium, i-hydroxypropyl methylcellulose, umgubo we-calcium onzima, umgubo we-calcium womlotha wamanzi.

1. Kwimveliso yokwenyani, ukuze kukhawuleziswe ukubola, ubushushu be-calcination budla ngokwandiswa bube yi-1000-1100 °C. Ngenxa yobukhulu obukhulu bezinto eziluhlaza ze-limestone okanye ukusasazwa kobushushu obungalinganiyo kwi-oven ngexesha le-calcination, i-lime idla ngokuba ne-lime engatshiyo kunye ne-lime etshiyo kakhulu. I-calcium carbonate kwi-lime engatshiyo ayitshiyo ngokupheleleyo, kwaye ayinawo amandla adibeneyo ngexesha lokusetyenziswa, angenako ukunika amandla aneleyo adibeneyo kwi-putty, nto leyo ekhokelela ekususweni komgubo okubangelwa bubunzima obungonelanga kunye namandla e-putty.

2. Okukhona umxholo we-calcium hydroxide ephezulu kumgubo we-calcium womlotha, kokukhona ubulukhuni be-putty buvela ngcono. Ngokwahlukileyo koko, okukhona umxholo we-calcium hydroxide ephantsi kumgubo we-calcium womlotha, kokukhona ubulukhuni be-putty busiba bubi kwindawo yokuvelisa, nto leyo ebangela ingxaki yokususwa komgubo kunye nokususwa komgubo.

3. Umgubo we-ash calcium uxutywe nomgubo omkhulu we-calcium onzima, nto leyo ebangela ukuba umxholo womgubo we-ash calcium ube sezantsi kakhulu ukuze unike ubulukhuni namandla aneleyo kwi-putty, nto leyo ebangela ukuba i-putty iwele umgubo. Umsebenzi ophambili we-putty powder kukugcina amanzi, ukubonelela ngamanzi aneleyo okuqinisa umgubo we-ash calcium, kunye nokuqinisekisa ukusebenza okwaneleyo kokuqina. Ukuba kukho ingxaki ngomgangatho we-hydroxypropyl methylcellulose okanye umxholo osebenzayo uphantsi, ukufuma okwaneleyo akunakubonelelwa, okuya kubangela ukuba ukuqina kungabi kwanele kwaye kubangele ukuba i-putty iwele umgubo.

Kunokufumaneka koku kungasentla ukuba umgangatho we-hydroxypropyl methylcellulose uphantsi kakhulu kwaye awunakukwazi ukufezekisa isiphumo esithile, kwaye umgubo we-putty uya kuwa. Isizathu esiphambili yi-gray beggar heavy calcium.
