Ngaba isenzeko se-efflorescence kudaka ezinxulumene ne-hydroxypropyl methylcellulose?

Isenzeko se-efflorescence kukuba: ikhonkrithi eqhelekileyo yi-silicate, kwaye xa idibana nomoya okanye ukufuma eludongeni, i-ion ye-silicate ifumana impendulo ye-hydrolysis, kwaye i-hydroxide eyenziwayo idibanisa kunye ne-ion zetsimbi ukwenza i-hydroxide ene-solubility ephantsi (ipropathi yemichiza I-alkaline), xa iqondo lokushisa liphakama, umphunga wamanzi uphuphuma, kwaye i-hydroxide ikhutshwe eludongeni. Ngokunyuka kancinci kwamanzi, i-hydroxide iyancipha phezu kwesamente yekhonkrithi. Ngokuhamba kwexesha, ipeyinti yokuqala yokuhlobisa Okanye ipeyinti kunye nezinye izinto ziphakanyiselwe phezulu kwaye azisayi kubambelela eludongeni, kwaye kuya kuba mhlophe, ukukhupha, kunye nokukhupha. Le nkqubo ibizwa ngokuba yi "pan-alkali". Ke, ayisiyiyo i-ubiquinol ebangelwa yi-hydroxypropyl methylcellulose.

Umthengi uthe isenzeko: grout etshiziweyo ayenzileyo iya kuba pan-alkali eludongeni lwesamente, kodwa akayi kuvela kudonga lwezitena ezivuthayo, nto leyo ebonisa ukuba iasidi ye-silicic kwisamente esetyenziswa eludongeni lwesamente Ityuwa eninzi kakhulu (ngokunamandla). ityuwa yealkali). I-efflorescence ebangelwa kukuba ngumphunga wamanzi asetyenziswa kwi-spray grouting. Nangona kunjalo, akukho silicate eludongeni lwezitena ezitshisiweyo kwaye akukho efflorescence iya kwenzeka. Ke ngoko, ukwenzeka kwe-efflorescence akunanto yakwenza nokutshiza.

Isisombululo

1. Umxholo we-silicate we-samente yekhonkrithi yesiseko uyancitshiswa.

2. Sebenzisa i-anti-alkali back coating agent, isisombululo singena kwilitye ukuvimba i-capillary, ukuze amanzi, i-Ca (OH) 2, ityuwa kunye nezinye izinto zingenako ukungena, kwaye zinqumle indlela ye-pan-alkaline phenomenon.

3. Ukuthintela ukungena kwamanzi, musa ukufafaza amanzi amaninzi ngaphambi kokwakhiwa.

Unyango lwe-pan-alkaline phenomenon

I-ejenti yokucoca ilitye efflorescence kwimarike ingasetyenziswa. Le arhente yokucoca ilulwelo oluguquguqukayo olungenambala olwenziwe ngama-non-ionic surfactants kunye nezinyibilikisi. Unempembelelo ethile ekucoceni kwezinye iindawo zamatye zendalo. Kodwa ngaphambi kokusetyenziswa, qiniseka ukuba wenze ibhloko encinci yovavanyo lwesampulu ukuvavanya isiphumo kwaye uthathe isigqibo sokuba uyisebenzise.
