Indima ye-hydroxypropyl methylcellulose kwi-putty
Ukususela ekuxineni, ukugcinwa kwamanzi kunye nokwakhiwa kwemisebenzi emithathu.
Ukuqina: I-Cellulose inokugqithwa ukuze inqunyanyiswe, gcina isisombululo esifanayo kwaye singaguquguquki, kwaye uxhathise ukugoba. Ukugcinwa kwamanzi: Yenza i-putty powder yome kancinci, kwaye uncedise ukuphendula kwe-ash calcium phantsi kwesenzo samanzi. Ukwakhiwa: I-Cellulose inefuthe lokuthambisa, elinokwenza ukuba i-putty powder ibe nokusebenza kakuhle. I-Hydroxypropyl methylcellulose ayithathi nxaxheba kuyo nayiphi na i-chemical reaction kwaye idlala indima yokuncedisa kuphela. I-putty powder yongezwa ngamanzi ukudibanisa udonga, oluyi-chemical reaction, 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 kunye nomoya, ngelixa i-hydroxypropyl methyl Cellulose igcina nje amanzi kwaye incedisa ukusabela okungcono kwe-ash calcium, yona ngokwayo engathathi nxaxheba kuyo nayiphi na impendulo.
Okokuqala sihlalutya izizathu zokuhla komgubo we-putty kwizinto eziluhlaza ze-putty: uthuthu lwe-calcium powder, i-hydroxypropyl methylcellulose, i-powder enzima ye-calcium, i-ash ash calcium powder.
1. Kwimveliso yangempela, ukwenzela ukukhawulezisa ukubola, ukushisa kwe-calcination kudla ngokunyuka ukuya kwi-1000-1100 ° C. Ngenxa yobukhulu bemathiriyeli yekalika okanye ubushushu obungalinganiyo ekuhanjisweni kweziko ngexesha lokubalwa, ikalika ikholisa ukuba nekalika engabaselweyo kunye nekalika etshiswe ngokugqithisileyo. I-calcium carbonate kwi-lime e-underfire ayichithwanga ngokupheleleyo, kwaye ayinakho amandla okubambisana ngexesha lokusetyenziswa, elingenakukwazi ukunika amandla okubambisana okwaneleyo kwi-putty, okubangelwa ukukhutshwa kwepowder okubangelwa ubunzima obunganeleyo kunye namandla e-putty.
2. Ukuphakama komxholo we-calcium hydroxide kwi-powder ye-ash calcium, ngcono ukuqina kwe-putty eveliswayo. Ngokuphambene noko, i-calcium hydroxide ephantsi kwi-powder ash ash, imbi ngakumbi ubunzima be-putty kwindawo yokuvelisa, okubangelwa ingxaki yokukhutshwa kwe powder kunye nokususwa kwe powder.
3. I-ash calcium powder ixutywe kunye nenani elikhulu le-powder enzima ye-calcium, ebangela ukuba umxholo we-ash calcium powder ube phantsi kakhulu ukubonelela ngobunzima obaneleyo kunye namandla kwi-putty, ebangela ukuba i-putty ilahle i-powder. Umsebenzi oyintloko we-putty powder kukugcina amanzi, ukubonelela ngamanzi okwaneleyo ukuqina kwe-ash calcium powder, kunye nokuqinisekisa umphumo owaneleyo wokuqina. Ukuba kukho ingxaki kumgangatho we-hydroxypropyl methylcellulose okanye umxholo osebenzayo uphantsi, umswakama owaneleyo awunakunikwa, okuya kubangela ukuba ukuqina kunganelanga kwaye kubangele ukuba i-putty ilahle i powder.
Inokufunyanwa ngasentla ukuba umgangatho we-hydroxypropyl methylcellulose umpofu kakhulu kwaye awukwazi ukufikelela kwisiphumo esithile, kwaye i-putty powder iya kuwa. Esona sizathu si-grey beggar i-calcium enzima.
