Nzira yekudzorera sei simende base caulk alkalinity? Mhedzisiro yekuwedzera calcium formate haina kujairika?

Vanhu vanoita mapurojekiti ekuvaka vanoziva kuti kudzoka idambudziko rinowanzoitika muzvigadzirwa zvesilicate. Mumakore achangopfuura, kuitira kuderedza kuitika kwedambudziko iri rinowanzoitika, indasitiri yekuvaka yakashandisa ceramic tile caulk kuiisa kune simenti. 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 yakasviba yekunze madziro caulking zvinhu uye yemukati madziro caulking zvinhu, uye iyo caustic kudzoka inowanzoitika munguva yechando yekuvakwa kwezuva remhute kana madziro ekunze mushure measingasviki maawa makumi maviri nemana mushure mekuvakwa, kuchena kwenzvimbo uye kuchena kwekristaro zvinhu kunaya, iyo inokanganisa zvakanyanya kushongedza kwechigadzirwa checaulking.

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 yechinyakare caulking zvinhu.

Zvivakwa uye kusarudzwa kwe calcium formate

Calcium formate chigadzirwa cheupfu chena chine mamolecular formula C2H2Ca04, inogona kumhanyisa hydration rate yesimende, nekudaro ichivandudza simba rekutanga resimende-based caulk, saka kuwedzera huwandu hwakakodzera hwe.calcium formatekusvika pakugadzirwa kwechando chesimenti-based caulk inofanira 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 material. Munguva yechando yekugadzira sisitimu-based joint filler, 1-2% calcium formate content inogona kuderedza zvakanyanya kudzoka alkali ye simenti-based joint filler.
