Mhedzisiro yekuwedzera calcium formate haina kujairika
Vese vanoita mapurojekiti ekuvaka vanoziva kuti caustic acid kudzoka idambudziko rakajairika rezvigadzirwa zve tridacidacin. Mumakore achangopfuura, kuitira kuderedza dambudziko rakajairika rekudzoka kwecaustic acid, indasitiri yekuvaka yakaisa tile caulk kune simende. Sedhaka rekutanga simba mumiriri, calcium formate inoshandiswa zvakanyanya nekuda kweiyo yakasarudzika zvivakwa, izvo zvinogona kusimudzira kuoma kwesement-based joint fillers uye kuvandudza simba rekutanga resimende-based joint fillers.
Iyo caulking zvinhu zvakakamurwa kuita rima rekunze madziro caulking zvinhu uye yemukati madziro caulking zvinhu, nepo caustic kudzoka kunowanzoitika mukuvakwa kwechando mumazuva emhute kana madziro ekunze mushure mekuvakwa mukati meawa isingasviki makumi maviri nemana mushure mekunaya kwemvura kuchena, uye kune white crystal material precipitation, iyo inokanganisa zvakanyanya kushongedza kwechigadzirwa che caulking.
Inowanzo shandiswa caulking zvinhu ndezvi: chena simende, putty poda, caulking agent, sealant uye zvichingodaro. Pakati pezvinhu izvi, simende chena uye putty poda zvinhu zvechinyakare caulking, asi zvese zviri zviviri izvi zviri kushomeka mukuita. Iko kushandiswa kwecalcium formate kwakakwirira kune echinyakare caulking zvinhu,
Zvivakwa uye kusarudzwa kwe calcium formate
Calcium formate chigadzirwa cheupfu chena, chinogona kukurumidza kuwedzera hydration ye simenti, nekudaro ichivandudza simba rekutanga resimende-based caulk, saka kuwedzera huwandu hwakakodzera hwecalcium formate kune yechando kugadzirwa kwecement-based caulk kunofanirwa kukurumidza kuumbwa kweCSH gel, nokudaro kuderedza kuitika kwekudzoka alkali.
Kugadzirwa kweiyo alkali chiyero hakuzongokanganiswa nemamiriro ekuvaka, ceramic tile sezvo hwaro kazhinji ndiyo inokonzera dambudziko. Kusarudzwa kweakakodzera calcium formate zvigadzirwa uye dosi yakakosha kuvandudza anti-alkali pfuma ye simende-based joint fillers. Mumwaka wechando wekugadzira simiti-based joint fillers, 1-2% calcium formate content inogona kuderedza zvakanyanya kudzoka alkali ye simenti-based joint fillers.
