Iimpawu kunye namaqhezu Basic haydite

ngodongwe eYandisiweyo - kukho izinto nokusingqongileyo kusetyenziswa usambathisa. It is a granules misindo ezo zifunyenwe kwinkqubo badubula nodongwe. Inkqubo yokudala imathiriyeli luquka amanyathelo ezimbalwa.

Ekuqaleni, udongwe kutyhobozela ukuba ziphunyezwe yi usengxakini elibukhali thermal. Ngenxa yoko, kunokwenzeka ukuba bafumane granules misindo. Umphezulu engaphandle ye imveliso inyibilikiswa, yaye ngenxa yoko ke oluzinzileyo ixesha elide, kwakunye lokuzuza ukukwazi ukumelana zonke iintlobo mpembelelo. Ayikwazi endingafanele kubizwa ngokuba ingozi eyayichaza izinto iye yazuza ithandwa kangaka namhlanje, kuba phakathi zalo eziluncedo - ukukwazi omkhulu ukugcina ubushushu.

incazelo

eyandisiweyo amaqhezu zodongwe zinokuba nomahluko, le parameter kuxhomekeke ubuchwepheshe. Ukususela inkqubo yokuvelisa kwakhona kuxhomekeke ukuba kuya kubakho izinto wathi iimpawu quality kufanelekile. Phakathi mpawu ziphambili ziphawulwe:

• umbethe;
• inqanaba eliphezulu amandla;
• ukumelana ubumanzi;
• kwalo;
• ireshiyo ngokupheleleyo iindleko nomgangatho.

Keramzit babe kude ngenxa yokuba iye isandi ezibalaseleyo kunye yokugquma nobushushu, imichiza inertness ezahlukeneyo, akoyiki lomlilo, kwaye phantsi ukubola. Xa befunda le nto, kubalulekile ukwazi kungekhona oko iqhekeza eyandisiweyo ngodongwe zikhona, kodwa ke iintsilelo, leyo kufuneka kwaziwe ukuba isiqhelo sokuba le zithutha ukufunxa ulwelo, ukuze ngokuthe ngcembe koma. Ezi granules zibuthathaka, le inkosi kufuneka ayisayi kulityalwa kwinkqubo izinto ligcwale. Phakathi kwezinye izinto, udongwe eyandisiweyo uyasetyenziswa kakuhle nje backfill elomileyo.

iipropati key

Njengoko yaziwa, izakhiwo zokuhlala ngezitena cozier kunye kunomzimba ezo zazakhiwe eziphathekayo. Clay, nto leyo ufakwa unyango ubushushu, esebenza njenge umqhubi kunokuba ihlwempu ubushushu nengqele. Ukwakha udaka eyandisiweyo uneempawu ezifana, oku kubangelwe isakhiwo amazwe. Noko ke, abathengi abaninzi bezibuza ukuba yintoni na conductivity wobushushu lo mbandela. Le parameter avareji 0.12 W / MK. Noko ke, simele uthathe ingqalelo izihlobo. Le granules babe nezinye iipropati ukuba uzenze athandwe kangaka.

Kufuneka kuqatshelwe amandla. Xa ezi mvavanyo ziqhutywe kwi ucinezelo, bavumela ukuba siqonde ukuba udongwe eyandisiweyo wabatshabalalisa-13% amanqaku ewonke. Oku kukhokelela ekubeni ithuba yokudala maleko ukubekwa izinto enikiweyo. Xa kufikwa apho umbandela eyandisiweyo, oko lungohlulwa lube iintlobo eziliqela, iyileyo abe mninzi ethile.

Ukuba uphawu M450 iqhekeza eyahlukileyo kuleyo-10 ukuya kwi-20 mm, lexinene kule meko kufana 440 kg / m ^3. Ukuba, ke, phambi kokuba umaka M500, ukuxinana yalo 465 kg / m ^3. Amaqhezu zodaka eyandisiweyo - ayiyiyo kuphela ukhetho ekufuneka ifundwe. Kubalulekile ukwazi kwakhona malunga ubunzima ethile, wenza njengoko inani ofanelekileyo uluhlu 0.95 g / cm ^3. Ngoxa loxinano bulk kuxhomekeke ngqo kwizinto ezithile, apha ziquka ubungakanani okuziinkozo. Ngoko, xa eyandisiweyo amaqhezu ngodongwe-30 mm nganye cubic meter izinto ziya nobunzima 340 kg.

Ukusetyenziswa kwe ngodongwe eyandisiweyo

Ngophanya nje lweliso, kusenokubonakala ngathi ukuba imihlaba ukusetyenziswa nodongwe eyandisiweyo ingabi ebanzi, kodwa ayikho. Le granules othile kakuhle ubushushu, ngoko endlwini yokugquma loo mavoko. Iimpawu ezibonakalayo uvumele ukusetyenziswa kwayo usambathisa thermal of iisilingi, imigangatho ezisongwayo of kophahla. Yayisebenzisa ibloko eziphathekayo njengokuba nwebu ngxabano. Le granules zingasetyenziswa njengesiseko ngokuyila screed eziphathekayo.

izinto ezisetyenziswa xa nokulahlwa lesiseko. Ngenxa ukusetyenziswa ngodongwe eyandisiweyo, kunokwenzeka ukuba kunciphisa ubunzulu isiseko bookmarks ekhaya izihlandlo-2, oku konga eziphathekayo kwaye uthintele ukuqanda yomhlaba ngeenxa isiseko. ngodongwe eYandisiweyo esetyenziswa nayo xa kusakhiwa ehomereni, umbhobho ngokubekwa, ngokunjalo iindlela yolwabiwo egadini. Yisebenzise kwakhona ukudala inkqubo yokukhupha amanzi evumela ukuba kufumaneke izivuno eziphezulu.

iqhekeza

Le nkcazelo ingentla yenziwa yi imigangatho yesizwe elawula amaqhekeza. Le parameter kuyohluka-5 ukuya kwi-10; 10 ukuya ku-20 yaye ukusuka mm-20 ukuya kuma-40. Emva kokuhlolisisa amaxwebhu, uyakwazi ukuqonda ukuba lokufaka ngodongwe eyandisiweyo yahlulwe iintlobo-10, ezahluke ezixineneyo, le parameter kuyohluka ukusuka 250 ukuya 800.

Iintlobo eziphambili: kwandiswa uhlalutye udongwe

ngodongwe eyandisiweyo, amaqhekeza, ixabiso eya kuba umdla umboleki, inikwa ezithengiswayo ngohlobo eyandisiweyo luhlalu nodongwe. ixabiso layo ngemeta ngu 1350 engange. Le nto iye ifomu ngeengqalutye kunye kumphezulu aneentunja leyo kunyibilika iintaba phantsi ubushushu.

Ezi mveliso zibe seqanda, kwaye umphezulu ipeyintiweyo ngombala emnyama omdaka. Ekuveleni abamnyama ebonakalayo. Oku izohlwayo ngodongwe eyandisiweyo ineenkalo kumqolo we-5 mm. Ubuninzi Isalathisi ifikelela 40 mm. Phakathi mpawu ziphambili kufuneka zenziwe manzi, kwakunye ukungabikho kwezinto contraindicated yesamente, kunye ukumelana nomlilo.

kwandiswa leke ukuba ubumba

Le nto ifumaneka ngokukhanywa amaqhosha ngodongwe foamed ubunzima eyandisiweyo. Xa kuthelekiswa luhlalu, ngoko ke izinto ine imilo emboxo. Ekuvelisweni iimpawu zendalo ngodongwe ezisetyenziswayo, kwaye utshintsho kwi imeko lokugqibela phantsi kwempembelelo ubushushu.

kwandiswa Isanti ubumba

Manufacturing eyandisiweyo isanti udongwe ekubeni enye yeendlela ezininzi. Eyokuqala ibandakanya ukusetyenziswa weziko rotary, owesibini - usebenzisa iziko nkqo, ngelixa lwesithathu lubandakanya ukusetyenziswa kobugcisa ngoomatshini. Ukuze ufumane 0,5 m ³ zesanti kufuneka achithe cubic meter ugqibile nodongwe eyandisiweyo. Ukuxinana zesanti ezinjalo ziyahluka ukusuka kg 500 ukuya kuma-700 / m ^3.

Ukukhethwa amaqhezu ukuba ngokubekwa emgangathweni

Umgangatho ngodongwe eYandisiweyo apho iqhezu idla iyahluka ukusuka ku-5 ukuya kwi-10 mm, sisiseko isisombululo apho idityaniswe esantini, igrabile kunye namanzi. ngodongwe eYandisiweyo bamoya Ilitye iqhezu isusela ukususela kwi-10 ukuya kwi-14 mm, amaxesha amaninzi asetyenziswa ekwenzeni izinto. Ukuba uyazibuza into iqhezu umgangatho ngodongwe eyandisiweyo iza kusetyenziswa, kufuneka sinikele ingqalelo kwakhona njengamasuntsu ngodongwe eyandisiweyo, esetyenziswa ukupakisha ukukhanya imigangatho bomelele yaye babe ubukhulu mm-5 ukuya kuma-40. Noko ke, xa kuxutywa kuyimfuneko ukusebenzisa iqhezu kuluhlu ka-5 ukuya kwali-10 okanye 10 ukuya kuma-20 okanye ukusuka 20 ukuya kuma-40 mm. Xa kukho imfuneko amalungiselelo screed obhityileyo, ukusetyenziswa eyandisiweyo udongwe isanti iqhezu ayikho ngaphezu kwe-5 mm. kwandiswa iqhekeza udongwe likhethe ukuba tie kuxhomekeka ukuba igumbi apho uceba ukusebenza kunye nobuchwepheshe iza kusetyenziswa ngexesha elifanayo.

isiphelo

Namhlanje, kwiingingqi ezahlukeneyo Russia yandisa izenzo ngodongwe njengesiseko sokwakha abaninzi. Lowo isebenzayo unako ukusebenzisa yayo ngenxa nokuveliswa izitampu iibhloko ukusuka M300 ukuya M500. Ethetha uqine, ngoko ke iimveliso data, eli nani ziyohluka ukusuka-5 ukuya 7.5 MPA.
