Khalase ea metsi

Modulus ea tharollo ea khalase ea metsi, e tsejoang hape e le sodium silicate solution kapa sodium silicate, ke parameter ea bohlokoa ho hlalosa litšobotsi tsa tharollo. Hangata modulus e hlalosoa e le karo-karolelano ea molar ea silicon dioxide (SiO₂) le alkali metal oxides (e kang sodium oxide Na₂O kapa potassium oxide K₂O) ka khalase ea metsi, ke hore, m(SiO₂)/m(M₂O), moo M e emelang alkaline. likarolo tsa tšepe (joaloka Na, K, joalo-joalo).

Taba ea pele, modulus ea tharollo ea khalase ea metsi e na le tšusumetso e kholo ho thepa le lits'ebetso tsa eona. Litharollo tsa khalase ea metsi tse nang le modulus e tlase hangata li na le ho qhibiliha ha metsi ho betere le viscosity e tlase, 'me li loketse maemo a itseng a ts'ebeliso a hlokang metsi a matle. Litharollo tsa khalase ea metsi tse nang le modulus e phahameng li na le viscosity e phahameng le ho khomarela ka matla, 'me li loketse liketsahalo tse hlokang matla le boima bo phahameng.
Ea bobeli, modulus ea tharollo ea khalase ea metsi hangata e pakeng tsa 1.5 le 3.5. Modulus ka har'a mefuta ena e nkoa e le eona e loketseng ka ho fetisisa bakeng sa tlhahiso ea indasteri le ts'ebeliso, hobane e ka etsa bonnete ba hore tharollo ea khalase ea metsi e na le solubility e itseng le metsi, 'me e ka fana ka ho khomarela le matla a lekaneng.
Ntlha ea boraro, modulus ea tharollo ea khalase ea metsi ha e tsitsitsoe, e ka laoloa ka ho fetola karo-karolelano ea lihlahisoa tse tala le mokhoa oa tlhahiso. Ka hona, maemong a fapaneng a ts'ebeliso, tharollo ea khalase ea metsi e nang le modulus e nepahetseng e ka khethoa ho latela litlhoko tse ikhethang.
Ea bone, modulus ea tharollo ea khalase ea metsi e boetse e amana haufi-ufi le mahloriso a eona, mocheso le lintlha tse ling. Ka kakaretso, ka ho eketseha ha mahloriso le ho fokotseha ha mocheso, modulus ea tharollo ea khalase ea metsi le eona e tla eketseha ka tsela e nepahetseng. Leha ho le joalo, phetoho ena ha e na moeli, empa e angoa ke lintlha tse fapaneng.
Ea bohlano, modulus ea tharollo ea khalase ea metsi ke parameter ea bohlokoa ho hlalosa litšoaneleho tsa eona, tse nang le tšusumetso e kholo ho thepa le lits'ebetso tsa eona. Lits'ebetsong tse sebetsang, hoa hlokahala ho khetha tharollo ea khalase ea metsi e nang le modulus e nepahetseng ho latela litlhoko tse ikhethang.
Motsoako oa tharollo ea khalase ea metsi ke parameter ea bohlokoa e amang thepa le litlamorao tsa ts'ebeliso ea khalase ea metsi. Khalase ea khalase ea metsi hangata e hlalosoa e le karolo e kholo ea sodium silicate (Na₂SiO₃).

1. Mefuta e tloaelehileng ea likhalase tsa khalase ea metsi

1. Khatello e akaretsang: Motsoako oa tharollo ea khalase ea metsi hangata ke 40%. Khalase ena ea metsi e tloaelehile haholo boenjiniere, 'me boima ba eona hangata ke 1.36 ~ 1.4g/cm³.
2. Tlhokomelo e tloaelehileng ea naha: Ho ea ka "GB/T 4209-2014" e tloaelehileng, tekanyo ea naha ea khalase ea metsi ke 10% ~ 12%. Sena se bolela hore karolo e kholo ea khalase ea metsi e lokela ho laoloa ka har'a moeli ona.

2. Lintlha tse amang khatello ea khalase ea metsi

Khalase ea likhalase tsa metsi e angoa ke lintlha tse ngata, ho kenyelletsa empa e sa felle ho tse latelang:

1. Boleng ba khalase ea metsi: Boleng ba lisebelisoa tse tala bo lekanya boleng ba khalase ea metsi e hlahisoang. Ha boleng ba khalase ea metsi bo le betere, ho eketsa khatello ea maikutlo.

2. Mocheso oa metsi: Mocheso oa metsi o na le tšusumetso e tobileng ho hlapolloa ha khalase ea metsi. Ha re bua ka kakaretso, ha mocheso oa metsi o phahame, khatello ea metsi e fokotseha.

3. Palo ea metsi a ekelitsoeng: Palo ea metsi a kentsoeng e ama ka ho toba mokoloko oa khalase ea metsi.

4. Nako ea ho susumetsa: Haeba nako ea ho sisinyeha e le khutšoanyane haholo, khalase ea metsi e ke ke ea e-ba le nako e lekaneng ea ho kopanya ka mokhoa o ts'oanang le metsi, e leng se tla lebisa tlhokomelong e sa nepahalang.

3. Mekhoa ea ho hlahisa mahloriso a khalase ea metsi

Ntle le ho e hlalosa ka likaroloana tse ngata, likhalase tsa metsi li ka hlahisoa ka likhato tsa Baume (°Bé). Baume ke mokhoa oa ho hlalosa bongata ba tharollo, e lekantsoeng ka Baume hydrometer. Khalase ea metsi ka har'a lisebelisoa tsa grouting hangata e hlahisoa e le 40-45Be, ho bolelang hore Baume ea eona e ka har'a mofuta ona.

4. Qetello

Motsoako oa tharollo ea khalase ea metsi ke paramente ea bohlokoa e lokelang ho khethoa ho latela maemo le litlhoko tse ikhethileng tsa ts'ebeliso. Tlhahisong ea boenjiniere le indastering, khatello ea likhalase tsa metsi e hloka ho laoloa ka nepo ho netefatsa boleng le botsitso ba sehlahisoa. Ka nako e ts'oanang, ho boetse hoa hlokahala ho ela hloko phello ea liphetoho tsa likhalase tsa khalase ea metsi ka thepa ea eona le liphello tsa kopo.
