Ingilazi yamanzi

I-modulus yesisombululo se-waterglass, eyaziwa nangokuthi isisombululo se-sodium silicate noma i-sodium silicate, iyipharamitha ebalulekile yokuchaza izici zesixazululo. I-modulus ivame ukuchazwa njenge-molar ratio ye-silicon dioxide (SiO₂) kanye ne-alkali metal oxides (njenge-sodium oxide Na₂O noma i-potassium oxide K₂O) ku-waterglass, okungukuthi, m(SiO₂)/m(M₂O), lapho u-M emele i-alkali. izakhi zensimbi (njenge-Na, K, njll.).

Okokuqala, i-modulus yesisombululo se-waterglass inomthelela omkhulu ezindaweni zayo nasekusetshenzisweni kwayo. Izixazululo ze-Waterglass ezine-modulus ephansi ngokuvamile zinokuncibilika okungcono kwamanzi kanye ne-viscosity ephansi, futhi zifanele izimo ezithile zohlelo lokusebenza ezidinga uketshezi oluhle. Izixazululo ze-Waterglass ezine-modulus ephakeme zine-viscosity ephakeme nokunamathela okuqinile, futhi zifanele izikhathi ezidinga amandla aphakeme nobulukhuni.
Okwesibili, i-modulus yesisombululo se-waterglass ngokuvamile iphakathi kuka-1.5 no-3.5. I-modulus ngaphakathi kwalolu hlu ibhekwa njengefaneleka kakhulu ekukhiqizeni nasekusetshenzisweni kwezimboni, ngoba ingaqinisekisa ukuthi isisombululo se-waterglass sinokuncibilika okuthile kanye ne-fluidity, futhi singanikeza ukunamathela okwanele namandla.
Okwesithathu, i-modulus yesisombululo sengilazi yamanzi ayinqunyelwe, ingalawulwa ngokulungisa isilinganiso sempahla eluhlaza kanye nenqubo yokukhiqiza. Ngakho-ke, ezimweni ezihlukene zohlelo lokusebenza, isisombululo sengilazi yamanzi ene-modulus efanelekile singakhethwa ngokuvumelana nezidingo ezithile.
Okwesine, i-modulus yesisombululo sengilazi yamanzi nayo ihlobene eduze nokuhlushwa kwayo, izinga lokushisa nezinye izici. Ngokuvamile, ngokwanda kokugxila kanye nokwehla kwezinga lokushisa, i-modulus yesisombululo sengilazi yamanzi nayo izokhula ngokufanele. Nokho, lolu shintsho alukona umugqa, kodwa luthintwa yizici ezihlukahlukene.
Okwesihlanu, i-modulus yesisombululo sengilazi yamanzi iyipharamitha ebalulekile yokuchaza izici zayo, enomthelela omkhulu ezindaweni zayo nasekusetshenzisweni kwayo. Ekusetshenzisweni okusebenzayo, kuyadingeka ukukhetha isixazululo sengilazi yamanzi nge-modulus efanelekile ngokuya ngezidingo ezithile.
Ukuhlushwa kwesisombululo sengilazi yamanzi kuyipharamitha eyinhloko ethinta izakhiwo kanye nemiphumela yokusetshenziswa kwengilazi yamanzi. Ukuhlangana kwengilazi yamanzi kuvame ukuvezwa njengengxenye enkulu ye-sodium silicate (Na₂SiO₃).

1. Uhla olujwayelekile lokuhlushwa kwengilazi yamanzi

1. Ukugxila okujwayelekile: Ukugxila kwesixazululo sengilazi yamanzi ngokuvamile kungama-40%. Lokhu kuhlangana kwengilazi yamanzi kuvame kakhulu kwezobunjiniyela, futhi ukuminyana kwayo kuvamise ukuba ngu-1.36~1.4g/cm³.
2. Ukugxilisa okujwayelekile okujwayelekile kukazwelonke: Ngokwezinga le-"GB/T 4209-2014", ukugxiliswa okujwayelekile okujwayelekile kukazwelonke kwengilazi yamanzi ngu-10%~12%. Lokhu kusho ukuthi ingxenye enkulu yengilazi yamanzi kufanele ilawulwe ngaphakathi kwalolu hlu.

2. Izinto ezithinta ukugcwala kwengilazi yamanzi

Ukugcwala kwengilazi yamanzi kuthintwa yizici eziningi, okuhlanganisa kodwa kungagcini kulokhu okulandelayo:

1. Izinga lengilazi yamanzi: Izinga lezinto ezingavuthiwe linquma izinga lengilazi yamanzi ekhiqizwayo. Ikhwalithi engcono yengilazi yamanzi, iyanda ukugxila.

2. Izinga lokushisa lamanzi: Izinga lokushisa lamanzi linomthelela oqondile ekuhlanjululweni kwengilazi yamanzi. Ngokuvamile, lapho izinga lokushisa lamanzi liphakeme, izinga lokushisa lamanzi liyancipha.

3. Inani lamanzi elengeziwe: Inani lamanzi elengeziwe lithinta ngokuqondile ukugcwala kwengilazi yamanzi.

4. Isikhathi sokuvuselela: Uma isikhathi sokuvuselela sifushane kakhulu, ingilazi yamanzi ngeke ibe nesikhathi esanele sokuxuba ngokulinganayo namanzi, okuzoholela ekugxilweni okungalungile.

3. Izindlela zokuveza ukugxila kwengilazi yamanzi

Ngaphezu kokuyiveza ngengxenyana enkulu, ukuhlangana kwengilazi yamanzi kungabuye ivezwe ngamadigri e-Baume (°Bé). I-Baume iyindlela yokuveza ukugxila kwesisombululo, esilinganiswa nge-Baume hydrometer. Ukugcwala kwengilazi yamanzi ezintweni zokugaya kuvame ukuvezwa njenge-40-45Be, okusho ukuthi i-Baume yayo ingaphakathi kwalolu hlu.

4. Isiphetho

Ukugxila kwesixazululo sengilazi yamanzi kuyipharamitha ebalulekile edinga ukunqunywa ngokuya ngezimo ezithile zohlelo lokusebenza kanye nezidingo. Ekwenziweni kwezobunjiniyela nezimboni, ukugcwala kwengilazi yamanzi kudinga ukulawulwa ngokunembile ukuze kuqinisekiswe ikhwalithi nokuzinza komkhiqizo. Ngesikhathi esifanayo, kuyadingeka futhi ukunaka umthelela wezinguquko ekugxilweni kwengilazi yamanzi ezindaweni zayo kanye nemiphumela yesicelo.
