### **1. Ubunzima obuthile (ubuninzi) bezitena ezibomvu**
Uxinaniso (ubunzima obuthile) bezitena ezibomvu budla ngokuba phakathi kwe-1.6-1.8 grams per cubic centimeter (1600-1800 kilograms per cubic meter), ngokuxhomekeke kubumbano lwemathiriyeli ekrwada (udongwe, i-shale, okanye i-gangue yamalahle) kunye nenkqubo yokuntywila.
### **2. Ubunzima besitena esibomvu esiqhelekileyo**
-* * Ubungakanani obuqhelekileyo * *: Ubungakanani bezitena obuqhelekileyo baseTshayina ngu * * 240mm × 115mm × 53mm * * (umthamo malunga * * 0.00146 cubic metres * *). Imitha enye ye-cubic yezitena ezibomvu eziqhelekileyo zelizwe malunga namaqhekeza angama-684.
-* * Ubunzima beqhekeza elinye * *: Kubalwa ngokusekelwe kuxinzelelo lwe-1.7 grams nge-cubic centimeter nganye, ubunzima beqhekeza elinye bumalunga * * 2.5 kilograms * * (uluhlu oluyinyani * * 2.2 ~ 2.8 kilogram * *). Malunga namaqhekeza angama-402 ezitena ezibomvu ezisemgangathweni ngokwetoni nganye
(Qaphela: Izitena ezingenanto okanye izitena ezikhaphukhaphu zinokuba khaphukhaphu kwaye kufuneka zihlengahlengiswe ngokohlobo oluthile.)

### **3. Iindleko zezitena ezibomvu**
-* * Uluhlu lwexabiso leyunithi * *: Ixabiso lesitena esibomvu ngasinye simalunga * * 0.3~0.8 RMB * *, ichatshazelwa zezi zinto zilandelayo:
-Ukwahluka kweNgingqi: Imimandla enemigaqo-nkqubo engqongqo yokusingqongileyo (efana nezixeko ezikhulu) ineendleko eziphezulu.
-* * Uhlobo lwemathiriyeli ekrwada * *: Izitena zodongwe ziyayekwa kancinci kancinci ngenxa yothintelo lokusingqongileyo, ngelixa izitena zeshale okanye zamalahle zixhaphake kakhulu.
-Isikali sokuvelisa: Imveliso enkulu inokunciphisa iindleko.
-Ingcebiso: Qhagamshelana ngokuthe ngqo nomzi-mveliso wasekuhlaleni weethayile okanye imarike yezinto zokwakha ukuze ufumane iikowuti zexesha lokwenyani.
### **4. Umgangatho weSizwe wezitena eziSintered (GB/T 5101-2017)**
Umgangatho wangoku eTshayina ngu * * "GB/T 5101-2017 Sintered Ordinary Bricks" * *, kwaye iimfuno eziphambili zobugcisa ziquka:
-Ubungakanani kunye nokubonakala: ukuphambuka kobungakanani obuvumelekileyo be-± 2mm, ngaphandle kweziphene ezinzulu ezifana nemiphetho elahlekileyo, iikona, iintanda, njl.
-Ibakala lamandla: lahlulwe ngamanqanaba amahlanu: MU30, MU25, MU20, MU15, kunye ne-MU10 (umzekelo, i-MU15 imele umyinge wamandla oxinzelelo we-≥ 15MPa).
-Ukuqina: Kufuneka ihlangabezane neemfuno zokumelana neqabaka (akukho monakalo emva kwemijikelo ye-freeze-thaw), izinga lokufunxa amanzi (ngokubanzi ≤ 20%), kunye nokuqhekeka kwe-lime (akukho kuphazamiseka kuyingozi).
-Iimfuno zokusingqongileyo: Kufuneka zihambelane nemida yesinyithi esinzima kunye nokungcola kwe-radioactive kwi-GB 29620-2013.
-
###* * Ukulumkela**
-Ezinye iindlela ezilungele indalo: Izitena ezibomvu zodongwe zithintelwe ukuba zingasetyenziswa ngenxa yomonakalo kumasimi, kwaye kuyacetyiswa ukuba kukhethwe izitena zodaka. Izitena ezinyibilikisiweyo ezenziwe ngenkunkuma eqinileyo njengezitena ze slag mgodini wamalahle, izitena zeshale, kunye nezitena zamalahle egangue.
-* * Ukwamkelwa kobunjineli * *: Ngexesha lokuthengwa kwempahla, kuyimfuneko ukuhlola isatifikethi sefektri kunye nengxelo yokuhlolwa kwezitena ukuqinisekisa ukuthotyelwa kwemigangatho kazwelonke.
