I-plinth, ngenxa yendawo yayo yokuvala emhlabathini kwaye, ngokufanelekileyo, umswakama, ulungele ukumanya ngokukhawuleza. Ingenziwa ngezinto ezihlukeneyo, kodwa ngokuqinisekileyo ityitye ikhethwa kakhulu. Kodwa kukho iintlobo ezininzi zezitena, ngokokuqala kufuneka ufumanise ukuba ityitye ilungele ukuthini, kwaye emva koko wenze isigqibo sokugqibela.
Indlela yokukhetha itena itekisi?
Ngelishwa, akukho mpendulo engabonakaliyo kumbuzo, ityitrha ingcono ukuyisebenzisela ukusila. Kuninzi kuxhomekeke kulawo okanye kwezinye iiparitha kunye neempawu zendawo yendlu.
Ngokuqhelekileyo, xa kwakhiwa indlu, abanini kufuneka bakhethe phakathi kweentlobo ezimbini zezitena kwi-sophisamic (i-calcined, ebomvu) ne-silicate (emhlophe).
Njengoko iimpikiswano eziphambili ekuthandweni komnye okanye olunye uhlobo zinganikwa impawu eziphambili zezobugcisa zezixhobo zokwakha. Ukuvavanya, wena ngokwakho unako ukucacisa ukuba yeyiphi itena efunekayo ukuze uxoke.
Ezi zimpawu ziquka amandla, ukunyuswa kwamanzi kunye nokunyuka kwamaqabunga. Ukuba sihamba ngendlela kwaye sivavanya amandla eembini eziphambili zezitena, ngoko ke, ziyahluka, kodwa ngokufutshane sinokuthi ukuba omnye kunye nowesibili babhekane nomthwalo owenziwe kubo. Ngokwemvelo, sithetha ngezitena eziqinile, kuba iinjongo ezingenasetyenziswayo azizisebenzisi.
Isalathisi sesibini ukunyuswa kwamanzi. Umlinganiselo ophezulu ngowama-6-13%, kwaye isitena se-silicate ngokupheleleyo kuloluhlu, ngelixa i-ceramic ngezinye ihamba ngaphaya kwayo, ibonisa izinga ukuya kwi-14%. Ngenxa yesakhiwo salo sangaphakathi, izitena ze-silicate zithatha ukunyuka ngokukhawuleza, kodwa i-ceramic igcina ixesha elide, elikhokelela ekubhujisweni kwayo.
Ukuxhatshazwa kwe-Frost yezinto ezixhomekeke ngqo kuxhomekeke kwisalathisi sangaphambili - ukumanyiswa kwamanzi. Ngako oko, kunokuthi i-trick silicate iyakumelana nokujikeleza kunye nokuqhaqha.
Nangona kunjalo, izitena ezibomvu ziqhelekileyo kwaye abaninzi banqwenela ukuyisebenzisa ngoku. Ngokwesilungiso, kunokuthiwa ukuba zombini iindidi zinelungelo lokusebenzisa ngexesha lokubeka isiseko sezindlu.
