Waterglass

Iyo modulus yewaterglass solution, inozivikanwawo sesodium silicate solution kana sodium silicate, yakakosha parameter kutsanangura maitiro emhinduro. Iyo modulus inowanzotsanangurwa seye molar ratio yesilicon dioxide (SiO₂) uye alkali metal oxides (senge sodium oxide Na₂O kana potassium oxide K₂O) mugirazi remvura, kureva, m(SiO₂)/m(M₂O), apo M inomiririra alkali. zvinhu zvesimbi (zvakadai seNa, K, nezvimwewo).

Kutanga, iyo modulus yemvura yegirazi mhinduro ine mhedzisiro yakakosha pane yayo zvivakwa uye mashandisirwo. Mvura yegirazi mhinduro ine yakaderera modulus kazhinji ine nani kunyungudika kwemvura uye yakaderera viscosity, uye yakakodzera kune mamwe mamiriro ekushandisa anoda mvura yakanaka. Mvura yegirazi mhinduro ine yakakwira modulus ine yakakwira viscosity uye yakasimba kunamatira, uye inokodzera zviitiko zvinoda kusimba kwepamusoro uye kuoma.
Chechipiri, iyo modulus yewaterglass solution inowanzova pakati pe1.5 ne3.5. Iyo modulus mukati meiyi chiyero inoonekwa seyakanyanya kukodzera kugadzirwa kwemaindasitiri uye kushandiswa, nekuti inogona kuve nechokwadi chekuti waterglass solution ine kumwe kunyungudika uye fluidity, uye inogona kupa yakakwana yekunamatira uye simba.
Chechitatu, iyo modulus yemvura girazi mhinduro haina kugadzikiswa, inogona kudzorwa nekugadzirisa iyo yakasvibira reshiyo uye maitiro ekugadzira. Naizvozvo, mumamiriro akasiyana ekushandisa, mhinduro yegirazi yemvura ine modulus yakakodzera inogona kusarudzwa zvinoenderana nezvinodiwa chaizvo.
Chechina, iyo modulus yemvura girazi mhinduro zvakare yakanyatso hukama nekutarisa kwayo, tembiricha uye zvimwe zvinhu. Kazhinji kutaura, nekuwedzera kwekutarisa uye kudzikira kwekushisa, iyo modulus yemvura girazi mhinduro ichawedzerawo zvinoenderana. Zvisinei, shanduko iyi haina mutsara, asi inokonzerwa nemhando dzakasiyana-siyana.
Chechishanu, iyo modulus yemvura girazi mhinduro ndiyo yakakosha parameter kutsanangura maitiro ayo, ayo ane hunhu hwakakosha pane ayo uye mashandisirwo. Mumashandisirwo anoshanda, zvinodikanwa kusarudza mhinduro yegirazi yemvura ine modulus yakakodzera zvinoenderana nezvinodiwa chaizvo.
Iko kusungirirwa kwegirazi remvura mhinduro ndiyo yakakosha parameter inobata zvivakwa uye mashandisiro ekuita kwegirazi remvura. Iko kusanganiswa kwegirazi remvura kunowanzo kuratidzwa sechikamu chikuru chesodium silicate (Na₂SiO₃).

1. Yakajairwa huwandu hwemvura yegirazi yekuisa

1. General concentration: Iko kusanganiswa kwegirazi remvura mhinduro kunowanzo 40%. Uku kuungana kwegirazi remvura kunonyanya kuwanda muinjiniya, uye huwandu hwayo hunowanzo 1.36 ~ 1.4g/cm³.
2. National standard concentration: Zvinoenderana ne "GB/T 4209-2014" chiyero, chiyero chenyika chegirazi remvura chiri 10% ~ 12%. Izvi zvinoreva kuti chikamu chikuru chegirazi remvura chinofanira kudzorwa mukati merudzi urwu.

2. Zvinhu zvinokanganisa kusangana kwegirazi remvura

Iko kusanganiswa kwegirazi remvura kunokanganiswa nezvakawanda zvinhu, zvinosanganisira asi zvisingaganhurirwe kune zvinotevera:

1. Unhu hwegirazi remvura: Hunhu hwezvinhu zvakasvibirira hunotaridza kunaka kwegirazi remvura rinogadzirwa. Izvo zviri nani kunaka kwegirazi remvura, iyo yakakwirira yekuisa pfungwa.

2. Tembiricha yemvura: Tembiricha yemvura ine simba rakananga pakuderedzwa kwegirazi remvura. Kazhinji, kana tembiricha yemvura yakakwira, inodzikira.

3. Kuwanda kwemvura yakawedzerwa: Nhamba yemvura yakawedzerwa inobata zvakananga kusanganiswa kwegirazi remvura.

4. Kukurudzira nguva: Kana nguva yekukurudzira ipfupi, girasi remvura harizove nenguva yakakwana yekusanganiswa pamwe chete nemvura, izvo zvinozoita kuti pave nemafungiro asina kururama.

3. Nzira dzekutaura girazi remvura concentration

Pamusoro pekuzvitaura muchidimbu chidimbu, huwandu hwegirazi remvura hunogonawo kuratidzwa mumadhigirii Baume (°Bé). Baume inzira yekuratidza kusangana kwemhinduro, iyo inoyerwa neBaume hydrometer. Iko kusanganiswa kwegirazi remvura mune grouting zvinhu kunowanzo kuratidzwa se40-45Be, zvinoreva kuti Baume yayo iri mukati meiyi renji.

4. Mhedziso

Iko kusungirirwa kwegirazi remvura mhinduro ndiyo yakakosha parameter inoda kutariswa zvinoenderana neyakajeka application mamiriro uye zvinodiwa. Mukugadzirwa kweinjiniya neindasitiri, kusungirirwa kwegirazi remvura kunoda kunyatsodzorwa kuti ive nechokwadi chemhando uye kugadzikana kwechigadzirwa. Panguva imwecheteyo, zvinodikanwa zvakare kutarisisa kukanganiswa kwekuchinja kwemvura yegirazi yekuisa pane yayo zvivakwa uye mashandisiro ekushandisa.
