Iglasi yamanzi

I-modulus yesisombululo se-waterglass, eyaziwa nangokuthi isisombululo se-sodium silicate okanye i-sodium silicate, iparameter ebalulekileyo ukuchaza iimpawu zesisombululo. I-modulus idla ngokuchazwa njengomlinganiselo we-molar we-silicon dioxide (SiO₂) kunye ne-alkali yensimbi oxides (njenge-sodium oxide Na₂O okanye i-potassium oxide K₂O) kwi-waterglass, oko kukuthi, m (SiO₂) / m (M₂O), apho i-M imele i-alkali. izinto zesinyithi (ezifana neNa, K, njl.).

Okokuqala, i-modulus yesisombululo se-waterglass inempembelelo ebalulekileyo kwiipropati zayo kunye nezicelo. Izisombululo ze-Waterglass ezinemodyuli esezantsi zihlala zine-solubility engcono yamanzi kunye ne-viscosity ephantsi, kwaye zifanelekile kwiimeko ezithile zesicelo ezifuna ukumanzi kakuhle. Izisombululo zeglasi yamanzi ezinemodyuli ephezulu zine-viscosity ephezulu kunye nokuncamathela okunamandla, kwaye zifanelekile kwizihlandlo ezifuna amandla aphezulu kunye nobunzima.
Okwesibini, imodyuli yesisombululo seglasi yamanzi ngokubanzi iphakathi kwe-1.5 kunye ne-3.5. I-modulus ngaphakathi kolu luhlu ithathwa njengeyona nto ifanelekileyo kwimveliso yoshishino kunye nesicelo, kuba inokuqinisekisa ukuba isisombululo se-waterglass sine-solubility ethile kunye ne-fluidity, kwaye inokubonelela ngokwaneleyo ukubambelela kunye namandla.
Okwesithathu, i-modulus yesisombululo seglasi yamanzi ayilungiswanga, inokulawulwa ngokulungelelanisa umlinganiselo wezinto eziluhlaza kunye nenkqubo yokuvelisa. Ngoko ke, kwiimeko ezahlukeneyo zesicelo, isisombululo seglasi yamanzi kunye nemodyuli efanelekileyo sinokukhethwa ngokweemfuno ezithile.
Okwesine, i-modulus yesisombululo seglasi yamanzi nayo ihambelana ngokusondeleyo noxinzelelo, ubushushu kunye nezinye izinto. Ngokuqhelekileyo, ngokunyuka koxinzelelo kunye nokuncipha kweqondo lokushisa, imodyuli yesisombululo seglasi yamanzi nayo iya kwanda ngokufanelekileyo. Nangona kunjalo, olu tshintsho alukho umgca, kodwa luchatshazelwa zizinto ezahlukeneyo.
Okwesihlanu, i-modulus yesisombululo seglasi yamanzi yiparameter ebalulekileyo yokuchaza iimpawu zayo, ezinempembelelo enkulu kwiipropati kunye nezicelo. Kwizicelo eziphathekayo, kuyimfuneko ukukhetha isisombululo seglasi yamanzi kunye nemodyuli efanelekileyo ngokweemfuno ezithile.
Ukuxinwa kwesisombululo seglasi yamanzi yiparameter ephambili echaphazela iipropati kunye nemiphumo yesicelo seglasi yamanzi. Ukuxinwa kweglasi yamanzi ngokuqhelekileyo kubonakaliswa njengeqhekeza elikhulu le-sodium silicate (Na₂SiO₃).

1. Uluhlu oluqhelekileyo lokugxininiswa kweglasi yamanzi

1. Ukugxininiswa ngokubanzi: Ukuxinwa kwesisombululo seglasi yamanzi ngokuqhelekileyo yi-40%. Le ngxubevange yeglasi yamanzi ixhaphake kakhulu kubunjineli, kwaye ukuxinana kwayo ngokuqhelekileyo yi-1.36~1.4g/cm³.
2. Ukugxininiswa komgangatho weSizwe: Ngokomgangatho we-"GB/T 4209-2014", umgangatho wesizwe weglasi yamanzi ngu-10% ~ 12%. Oku kuthetha ukuba inxalenye enkulu yeglasi yamanzi kufuneka ilawulwe ngaphakathi kolu luhlu.

2. Izinto ezichaphazela ukugxininiswa kweglasi yamanzi

Ukuxinana kweglasi yamanzi kuchatshazelwa zizinto ezininzi, kubandakanywa kodwa kungaphelelanga kwezi zilandelayo:

1. Umgangatho weglasi yamanzi: Umgangatho wemathiriyeli ekrwada umisela umgangatho weglasi yamanzi evelisiweyo. Umgangatho ongcono weglasi yamanzi, iphezulu yoxinaniso.

2. Ubushushu bamanzi: Ubushushu bamanzi bunempembelelo ngokuthe ngqo kwi-dilution yeglasi yamanzi. Ngokuqhelekileyo, okukhona ubushushu bamanzi buphezulu, kokukhona kusezantsi ukuxinana.

3. Isixa samanzi esongeziweyo: Ubungakanani bamanzi abongeziweyo buchaphazela ngokuthe ngqo ukugxilwa kweglasi yamanzi.

4. Ixesha lokuvuselela: Ukuba ixesha lokuvuselela lifutshane kakhulu, iglasi yamanzi ayiyi kuba nexesha elaneleyo lokudibanisa kunye namanzi, okuya kubangela ukugxininiswa okungachanekanga.

3. Iindlela zokubonisa ukugxininiswa kweglasi yamanzi

Ukongeza ekuyibonakaliseni ngamaqhezu obunzima, ukuxinana kweglasi yamanzi kunokubonakaliswa ngeedigri zeBaume (°Bé). I-Baume yindlela yokubonakalisa ukuxinwa kwesisombululo, esilinganiswa ne-Baume hydrometer. Ukuxinwa kweglasi yamanzi kwizinto zokucoca ngokuqhelekileyo kubonakaliswa njenge-40-45Be, oku kuthetha ukuba i-Baume yayo ingaphakathi kolu luhlu.

4. Isiphelo

Ukugxininiswa kwesisombululo seglasi yamanzi yiparameter ebalulekileyo ekufuneka igqitywe ngokweemeko ezithile zesicelo kunye neemfuno. Kwimveliso yobunjineli kunye nemveliso, ukuxinwa kweglasi yamanzi kufuneka kulawulwe ngokuchanekileyo ukuqinisekisa umgangatho kunye nokuzinza kwemveliso. Ngexesha elifanayo, kuyafuneka ukuba ubeke ingqalelo kwimpembelelo yokutshintsha kweglasi yamanzi kwiipropati zayo kunye nemiphumo yesicelo.
