Indima ye-hydroxypropyl methylcellulose ku-putty

Kusukela ekuqineni, ukugcinwa kwamanzi kanye nokwakhiwa kwemisebenzi emithathu.

Ukuqina: I-Cellulose ingaqiniswa ukuze imiswe, igcine isisombululo sifana futhi sihambisana, futhi imelane nokugoba. Ukugcinwa kwamanzi: Yenza i-putty powder yome kancane, futhi isize ukusabela kwe-calcium yomlotha ngaphansi kokusebenza kwamanzi. Ukwakhiwa: I-Cellulose inomphumela wokugcoba, ongenza i-putty powder isebenze kahle. I-Hydroxypropyl methylcellulose ayihlanganyeli kunoma yikuphi ukusabela kwamakhemikhali futhi idlala indima yokusiza kuphela. I-putty powder yengezwa ngamanzi ukuze ihlanganise udonga, okuyi-chemical reaction, ngoba kukhona ukwakheka kwento entsha i-calcium carbonate. Izingxenye eziyinhloko ze-ash calcium powder yilezi: ingxube ye-calcium hydroxide Ca(OH)2, i-calcium oxide CaO kanye nenani elincane le-calcium carbonate CaCO3. I-Ash calcium yakha i-calcium carbonate ngaphansi kwesenzo se-CO2 emanzini nasemoyeni, kuyilapho i-hydroxypropyl methyl I-Cellulose igcina amanzi futhi isize ukusabela okungcono kwe-calcium yomlotha, yona ngokwayo engahlanganyeli kunoma yikuphi ukusabela.

Okokuqala sihlaziya izizathu zokwehla kwempuphu ye-putty ezintweni zokusetshenziswa ze-putty: i-ash calcium powder, i-hydroxypropyl methylcellulose, i-heavy calcium powder, i-water ash calcium powder.

1. Ekukhiqizweni kwangempela, ukuze kusheshiswe ukubola, izinga lokushisa le-calcination livame ukukhushulwa lifike ku-1000-1100 °C. Ngenxa yobukhulu obukhulu bezinto zokusetshenziswa ze-limestone noma ukusatshalaliswa okungalingani kwezinga lokushisa kuhhavini ngesikhathi se-calcination, i-lime ivame ukuqukethe i-lime engashiswanga kanye ne-lime eshiswa kakhulu. I-calcium carbonate ku-lime engashiswanga ayiboli ngokuphelele, futhi ayinawo amandla okubambisana ngesikhathi sokusetshenziswa, okungenakunikeza amandla anele okubambisana ku-putty, okuholela ekususweni kwempuphu okubangelwa ukuqina okunganele namandla e-putty.

2. Uma okuqukethwe kwe-calcium hydroxide ku-ash calcium powder kuphakeme, kuba ngcono ukuqina kwe-putty. Ngokuphambene nalokho, uma okuqukethwe kwe-calcium hydroxide ku-ash calcium powder kuyanda, kuba kubi ukuqina kwe-putty endaweni yokukhiqiza, okuholela enkingeni yokususwa kwe-powder nokususwa kwe-powder.

3. Impuphu ye-calcium yomlotha ixutshwa nenani elikhulu lempuphu ye-calcium esindayo, okwenza okuqukethwe yimpuphu ye-calcium yomlotha kube phansi kakhulu ukuze kuhlinzekwe ubulukhuni namandla anele ku-putty, okubangela ukuthi i-putty iwele impuphu. Umsebenzi oyinhloko wempuphu ye-putty ukugcina amanzi, ukuhlinzeka ngamanzi anele okuqinisa impuphu ye-calcium yomlotha, nokuqinisekisa umphumela owanele wokuqina. Uma kunenkinga ngekhwalithi ye-hydroxypropyl methylcellulose noma okuqukethwe okusebenzayo kuphansi, umswakama owanele awukwazi ukuhlinzekwa, okuzokwenza ukuqina kungabi ngokwanele futhi kubangele ukuthi i-putty iwele impuphu.

Kungatholakala kusukela ngenhla ukuthi ikhwalithi ye-hydroxypropyl methylcellulose iphansi kakhulu futhi ayikwazi ukufeza umphumela othile, futhi i-putty powder izowa. Isizathu esiyinhloko yi-gray beggar heavy calcium.
