How kusarudza chidhinha muvira?

Pasinei zvose Kubudirira ose michina yakasiyana-siyana mumakore achangodarika, musha vazhinji vomunyika yedu kuramba neshungu vachishandisa vira anachronistic. Zvisinei, maererano rakavimbika uye nyore ichi mhando kudziyisa ichiri hapana kuenzana, asi nekuti zvakadaro nzira muzviitiko zvakawanda anoruramiswa. Pakuvaka mevira usakanganwa kuti vira tembiricha inogona kusvika 800 Celsius.

Naizvozvo harifaniri kushandiswa zvavo masonry zvidhina nokuti Stoves kwezvatiri havaratidzi. Zvimwe kushandisa fireclay refractory kana ayo dzakasiyana. Brick ichi chakagadzirwa kunyanya gobvu tsvuku nevhu, kudzingwa basa rinokosha rudzi, asi nekuda dhigirii kurwisa kune zvezvakatipoteredza ezvinhu vanotyaira nokure pomureza zvigadzirwa.

Kana kuisa chitofu, kuteerera chando kuramba kwemashoko yaishandiswa nemi. Oddly zvakakwana, asi zvidhina kilns vanofanira ive unhu uhwu zvizere. Kunyanya ichi ichokwadi panyaya apo vira iri mune imwe kamuri kuti neshungu chete nguva nenguva. Ndokusaka yezororo dzimba ndezvinorondedzerwa akapinza Stoves uye fireplaces ose fireclay zvidhina. Haasi chete chinonyanya refractories, asi anenge asingadi kutsemuka kunyange pasi pokudzora guru tembiricha nokufamba.

Pakati pezvimwe zvinhu, rinosimbisa yakanaka mashanga-yellow ruvara: zvakadai vira zvidhina, mapikicha izvo zvinogona kuonekwa mupepa zvakakwana kufanira chero yakarongedzwa uye midziyo yeimba. Zvinofanira kucherechedzwa kuti pasi chifukidziro chaiyo lacquer, riri pamusoro-rinomiririrwa ari indasitiri, unogona kuwana mashiripiti zvechokwadi runako ngaaone.

On yanhasi kuvaka musika refractory zvidhinha pamusoro yamavira (ndiko mutengo zvikuru yakakwirira) chinopiwa nenzira zvakanaka-siyana, asi kufara rwokusarudza havafaniri kuisa iwe mune akafa magumo. Sarudzai anowanzodanwa kushandiswa kutyaira uye pefiyumu: naBhaasha-5 uye yaBhaasha-8, iyo dzichavafukidza zvinodiwa svikiro kadikidiki chitofu wezvinonhuhwira anenge zviitiko zvose. Kana isu nezvazvo kusiyana izvi kwemarudzi maviri, vane diki: chete naBhaasha-8 angakudzivisai tembiricha kusvika 50 Celsius yakakwirira kazhinji, hazvina basa.

Uyezve, fireclay zvidhinha nokuti yamavira ndiyo yakakura kudarika kwayo "vashandi" mwero iri kukura, iyo hwezvekukurukurirana zvikuru kuiswa muitiro pacharo, kuwedzera kwazvo. Chokwadi izvi nokuti mutengo kwaiita zvinhu kazhinji inoruma. Zvikuru aakatipa geometric zvakarurama furnace zvidhina. Chero zvinofanira kutevedzerwa hadzina chinodzirwisa anoziva zvinokosha kuremekedza kukura uye akakwana evenness pakati mapfundo, kuisa choto kana chitofu.

Wechipiri chinokosha ndiko chemhando yepamusoro pakati nedhaka. Kunyanya, batira kunofanira kuitwa pamwe musono ukobvu haasi millimeters anopfuura mashanu, saka kuti kushaya oparesheni pano isingagamuchiriki. In yamavira dzakawanda nokuti ivhu zvidhina anoiswa pamusoro chichagadzirisa riri kuwedzerwa kuumba kana fireclay nezvakasanganiswa. Tinoratidza kushandisa GC-40 uye GC-50 simende, unhu zviri zvikuru akakodzera zvinangwa izvozvo.
