Indima ye-hydroxypropyl methylcellulose ku-putty

Indima ye-hydroxypropyl methylcellulose ku-putty

Kusukela ekuqinisweni, ukugcinwa kwamanzi kanye nokwakhiwa kwemisebenzi emithathu.

Ukuqina: I-Cellulose ingajiywa ukuze imiswe, igcine iyunifomu yesisombululo futhi ingaguquki, futhi imelane nokuwohloka. Ukugcinwa kwamanzi: Yenza i-putty powder yome kancane, futhi usize ukusabela kwe-ash calcium ngaphansi kwesenzo samanzi. Ukwakhiwa: I-Cellulose inomphumela wokugcoba, ongenza i-putty powder ibe nokusebenza okuhle. IHydroxypropyl methylcellulose ayibambi iqhaza kunoma yikuphi ukusabela kwamakhemikhali futhi idlala indima yokusiza kuphela. I-putty powder yengezwa ngamanzi ukuhlanganisa udonga, okuwukusabela kwamakhemikhali, ngoba kukhona ukwakheka kwento entsha ye-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 Cellulose igcina nje amanzi futhi isize ukusabela okungcono kwe-ash calcium, yona ngokwayo engabambi iqhaza kunoma yikuphi ukusabela.

Okokuqala sihlaziya izizathu zokuwa kwempuphu ye-putty ezintweni ezingavuthiwe ze-putty: i-ash calcium powder, i-hydroxypropyl methylcellulose, i-powder enzima ye-calcium, i-water ash calcium powder.

1. Ekukhiqizeni kwangempela, ukuze kusheshiswe ukubola, izinga lokushisa lokubala livame ukukhuphuka libe ngu-1000-1100 °C. Ngenxa yobukhulu bezinto zokusetshenziswa ze-limestone noma izinga lokushisa elingalingani kuhhovini ngesikhathi sokubala, umcako uvame ukuba nomcako ongashiswanga kanye nomcako oshiswe ngokweqile. I-calcium carbonate ku-lime engaphansi komlilo ayichithwanga ngokuphelele, futhi ayinakho amandla ahlangene ngesikhathi sokusetshenziswa, engakwazi ukunikeza amandla okwanele okubumbana ku-putty, okuholela ekukhishweni kwe-powder okubangelwa ubulukhuni obanele namandla we-putty.

2. Ukuphakama kwe-calcium hydroxide ku-ash calcium powder, kuba ngcono ukuqina kwe-putty ekhiqizwayo. Ngokuphambene nalokho, ukwehla kokuqukethwe kwe-calcium hydroxide emlotheni we-calcium powder, kubi nakakhulu ukuqina kwe-putty endaweni yokukhiqiza, okuholela enkingeni yokukhishwa kwe-powder nokususwa kwe-powder.

3. I-ash calcium powder ixubene nenani elikhulu le-calcium powder elinzima, elibangela ukuthi okuqukethwe kwe-ash calcium powder kube phansi kakhulu ukuze kunikeze ubulukhuni obanele namandla ku-putty, okwenza ukuba i-putty yehle i-powder. Umsebenzi oyinhloko we-putty powder ukugcina amanzi, ukuhlinzeka ngamanzi anele ukuze kuqiniswe umlotha we-calcium powder, nokuqinisekisa umphumela owanele wokuqina. Uma kunenkinga ngekhwalithi ye-hydroxypropyl methylcellulose noma okuqukethwe okusebenzayo kuphansi, umswakama owanele awukwazi ukuhlinzekwa, okuzokwenza ukuthi ukuqina kunganele futhi kubangele ukuba i-putty yehle i-powder.

Kungatholakala kulokhu okungenhla ukuthi ikhwalithi ye-hydroxypropyl methylcellulose impofu kakhulu futhi ayikwazi ukufeza umphumela othile, futhi i-putty powder izowa. Isizathu esikhulu i-gray beggar i-calcium enzima.
