Yintoni lexinene izitena?

Izitena - ukuba enye yezinto ezininzi idumileyo zokwakha. Uphethe inani iipropati ezibalulekileyo ezenza ezinye endaweni yazo. Izitena ukumelana imvula, unako ukumelana nemijikelo ezininzi yovalo, njl Enye iimpawu eziphambili zezinto zokwakha - .. Ingxinano. Sichaza umgangatho wayo ezifana conductivity thermal, ubunzima kunye namandla.

izitena ceramic

Abazaziyo zonke izinto ebomvu, nangona ubugcisa bale mihla avumele ukwandisa inani abangasekhoyo. Density izitena yodongwe uba ezahlukeneyo, umz. K. yena avelise iinjongo ezahlukeneyo. Iveliswe isitena ngodongwe, nowezonkana ezisicaba ezingenagwele, oveni ezizodwa. Sazabela lona phezu kwaye kuthembeke. Kwimeko yokuqala, loxinano izitena yodongwe yi-2000 kg / m ^3. It sibonisa ukuba porosity esezantsi namandla eliphezulu. Ngako oko izitena ezisetyenziselwa ukwakha iindonga umthwalo-ngokuzala kunye nezakhiwo, imiqolo njalo njalo. D.

izitena Ulenze ayikho obukhulu kangaka. Eli nani ngayo isusela 1100-1400 kg / m ^3. It ayinqweneleki ukusebenzisa ukwakhiwa kwezakhiwo umthwalo yawo. izitena Ulenze ezisetyenziselwa ukwakha iindonga ayisindi nokuzalisa isakhelo. Ngenxa yobubanzi balo, uneempawu ezibalaseleyo ubushushu thermal kunye nesandi.

izitena silicate

Eyenziwe umxube lime kunye nesanti. Le nto cheap, kufuneka zipeyintwe ngemibala ezininzi ezahlukeneyo, kodwa iba iyahlozinga (xa kuthelekiswa yodongwe), i enzima ukukhanya idlule ukubanda nobushushu. Ngenxa yezi mpawu libe lelona ukusetyenziswa ukwakhiwa ngezitena of zokwahlula wezasekhaya. Ukusetyenziswa kwale eziphathekayo ukwenza iindonga umthwalo ngokuzala ayamkelekanga. Kwakhona, musa ukuzisebenzisela ukwakhiwa ende yamaziko, t. To. Xa kokushushubezwa deforms.

Lexinene dust ngezitena corpulent yi 1800-1950 kg / ^m-3 kunye imigodi - 1100-1600 kg / m ^3.

izitena clinker

Iveliswe ukusuka udongwe owomileyo apho calcined kwiqondo lobushushu ephakamileyo. Ngenxa yoko, imveliso endibufumeneyo womelele kakhulu ixesha elide. Le nto ayikho ukoyika ngamathontsi kunye neemeko ezinzima yokusebenza. Ngoko ke, lisetyenziswa kwiindawo nomthwalo omkhulu: ukwenza iindlela, ukwakhiwa imigangatho komhlaba. Kulungile ukuthi kuziveza kunye nezindlu nayo.

Corpulent izitena clinker mninzi ifikelela 1900-2100 kg / m ^3, amandla - M1000. Le porosity ngaphantsi kwe-5%, ukuze izinto incinane ubethwa ukufuma. Products zenzelwe 100 imijikelo ngumkhenkce-obuhle. Noko ke, ukuveliswa isitena loo kakhulu uziindleko eziphezulu kakhulu yodongwe. Ngenxa yokuba izinto ezixineneyo ifunyenwe enzima kwaye inqanaba eliphezulu conductivity thermal.

izitena aluminous

Le izinto zokwakha ilungiselelwe iqondo lobushushu eliphezulu kakhulu, ukuba unako ukumelana ubushushu ukuya degrees 1600. Ngoko ke, izitena fireclay ingabizwa engangenwa kuphela kunye ezingatshiyo. Kubalulekile xa ngokubekwa ende yamaziko, maziko kunye nezinye izakhiwo apho ziya kuboniswa lobushushu eliphezulu. Ekubeni izinto isoloko isetyenziswa kokokuhombisa izinto ubuciko, sivelisa kuphela imilo esezantsi buxande, kodwa enhle, trapezoid kunye sphenoid. Izitena mninzi yakhona ukususela 1700 ukuya 1900 kg / cm ^3.

Noko ke, ingqalelo imveliso zicacisa hayi kuphela eyimveliso eziphathekayo, kodwa ezinye iinjongo. Ngoko ke, abaninzi iimpawu ziya ichazwe kanye indawo isicelo. Kuquka ukhetho izinto ziya kuxhomekeka kulo.

ejongene brick

Isetyenziselwe amaziko evela ngaphandle kwezakhiwo. ezifunwa High ezibekwe inkangeleko yayo. Brick kufuneka tyaba, ulalisa ecwebezelayo. yena ezibuhlazarha, ngaloo ndlela enze imisebenzi emibini. Umaleko engaphandle yezitena ngexesha le zinokuhonjiswa kwaye ngci. Ngokuba izinto amaziko yangaphandle lisetyenziswa imibala eyahlukileyo. ezahlukahlukeneyo imibala kuyafikelelwa yi ukusetyenziswa kobugcisa ukudutyulwa ezahlukeneyo, neenkqubo ubushushu kunye nokwakhiwa ubunzima nodongwe.

Lexinene ingaphakathi izitena ayikho kuluhlu ukususela 1300 ukuya 1450 kg / cm ³ porosity unako ukufikelela-14%. Oku kwanele ukuqinisekisa inqanaba eliphezulu amandla, kodwa musa ukulibala malunga iipropati ubushushu-zokwambathisa ezikhoyo. Kakhulu neemfuno yiqabaka izinto t. K. It abafowunelwa kunye nokusingqongileyo lwangaphandle.

izitena Private

Esetyenziselwa imisebenzi yangaphakathi, ulwakhiwo kweendonga njalo njalo. D. Kukho zohlukile izitena ophezulu-amandla, nto leyo isetyenziselwa ukwakhiwa kwezakhiwo umthwalo yawo. Kwimeko yokuqala, ngesalathisi ezifana ngezitena mninzi isusela ukususela 1100 ukuya ku-2000 kg / cm ^3, kuxhomekeka kwisicelo. Ngenxa yoko, ukuba bazalise isakhelo kunye / okanye isixhobo bulkheads lwangaphakathi kusetyenziswa izitena ezibuhlazarha, t. K. Ayisayi ukulayisha isiseko. Eendonga umphandle okanye nomthwalo-ethwala kungcono ukuthatha izinto eziphakamileyo-amandla. Izitena ezinoxinano kulo mzekelo kune 2000 kg / cm ^3.
