Mineral uboya: ukusebenza kunye GOST

Ukuthandwa enkulu of volo kwezimbiwa kubangelwa ikakhulu iindleko yabo kunye nokusebenza kakhulu. Le eziphathekayo ingasetyenziswa usambathisa thermal ezininzi ezahlukeneyo lwezoyilo - iindonga, uphahla kunye umgangatho zezindlu zabucala, imibhobho, izifudumezi, njl ...

Inkqubo yokudala

Njengoko izinto ekrwada, ekwenziweni kukho izinto ezifana Iizilebhu uboya bezimbiwa kusetyenziswa ilitye elingumfanekiso otyhidiweyo mlilo, iglasi, Ngokufutha eziko zeBlack. Le into viscous ashushu ikhutshwa kwindawo icentrifuge ezizodwa, apho (ngenxa sokumema emoyeni) uguqulwe enobunzima ezinezikhondo. Eminye yokuhlanganisa baziswa kulo. Ngokuqhelekileyo indima yazo nentlaka phenol-formaldehyde. Okulandelayo sticky "uboya" livela phantsi izileyi, zakha umaleko kakuhle kuyo. Ngelo xesha lokugqibela, izinto ziguyiwe ukuba amacwecwe isayizi oyifunayo.

Imicu kwezimbiwa uboya kunokwenziwa amalungiselelo ngendlela ingalawuleki kwaye aa Incopho na omnye komnye. Le ndlela yokugqibela kuthiwa izinto laminalnym onokuxinana kunye neqondo conductivity thermal enkulu, na amandla aphezulu. Ngamanye amaxesha Iizilebhu yezimbiwa uboya njo elinye icala le-aluminiyam eneli zamafu.

The degree of iyawulwa umlilo

Inzuzo ephambili yoboya izimbiwa xa kuthelekiswa nezinye insulators kugqalwa Ukungabinakutsha yayo. Unako ukusebenzisa le nto ngenxa zokwambathisa iindawo zabo lobushushu kufika kumgomo 400 Celsius. Kungenxa yoko le nto yezimbiwa iiplanga ezi yokwambathisa efanelekileyo ukuze boilers kunye amaziko kweentlobo ezahlukeneyo. Ukunyibilika Imicu abangelwe ziqale kuphela emva kweeyure ezimbini ukwenekwa lobushushu 1000 degrees. Oku oyintsobi omhle kakhulu. Ngokumalunga lobushushu kokugquma le, ngoko ngaphandle isilo eziphathekayo ukumelana degrees 750. Group of iibhodi yezimbiwa Ukungabinakutsha - KM0. Xa iintlobo ngefoyile ye - KM1.

The degree of conductivity thermal

Eyona njongo ephambili yale uboya izimbiwa - ukukhusela amakhaya, izixhobo kunye nonxibelelwano ukusuka yokubanda. conductivity eyamkelekileyo thermal yale zokufunda kumiselwa GOST 4640-2011. Le rate kuyahlukana nedlela lobushushu kokugquma kwaye inokuba ukusuka 0,038 W / (MK) kubushushu degrees 10 ukuya 0,070 W / (MK) ngama-300. Ngoko ke, ukukwazi ukugcina ubushushu, le nto mkhulu insulators ezininzi zale mihla. Olu phawu kungenxa isakhiwo aneentunja kunye nenani elikhulu lamanqanaba moya.

mninzi

Le izinto index afana neebhodi yezimbiwa uboya ubushushu, ingahluka ngaphakathi enkulu kangangoko nengenzulu (30-220 kg / m ^3). Uphakamile lexinene kwi nembasa, sasasaza umthwalo ungakwazi ukumelana. Kuba esi salathisi, uboya izimbiwa ukuba kalukhuni ihlelwa ngokwezintlu ezintathu:

• ingxinano Low (ne30-50 kg / m ^3). Le uboya kakhulu kusetyenziswa usambathisa thermal kumphezulu tye.
• ingxinano Medium (60-75 kg / m ^3). Olu hlobo amaninzi kusetyenziswa ikheswa zonke iintlobo ufakelo zobugcisa.
• ezixineneyo (80-175 kg / m ^3). Ezo iipleyiti zingasetyenziswa iindonga zokwambathisa ngaphakathi okanye izakhiwo ngaphandle.
• ezixineneyo kakhulu (180-200 kg / m ^3). Olu hlobo luqhele ukusetyenziswa usambathisa thermal uphahla.

Lexinene a izinto ezifana yezimbiwa uboya ekubhalwe kuso, - ngesalathisi ocacisa ukukwazi kwabo kuphela ukumelana umthwalo. The degree of conductivity thermal iye phantse akukho isiphumo.

manzi

ukumelana Luphantsi ukuya umthondo amanzi - enye kubakho iingxaki ezimbalwa, okuye uboya bezimbiwa. GOST ukuqinisekisa ukuthobela imigaqo eziphathekayo ngokwemiqathango yokunganyangeki amanzi kufuna iimvavanyo ezithile. plate Ngaloo ezivela kwiindawo ezahlukeneyo zavavanywa (ama-20-30 grams). Ngaphezu bebekwe kwisitya porcelain kwaye calcined kwiqondo lobushushu degrees 600 ukuya ukususa ukungcola organic. Ubunzima ke bayisile ibe ngumgubo, ogalelwe ioli esisahlulo amathontsi ambalwa ethanol, kulandele Ukongeza of a zehydrochloric acid kancinane. Ngaphezu koko, amandla electrode uvikivwa pH imitha. Emva kwemizuzu elishumi ukukhwezela, pH lalibalwa kweziyobisi. ukumelana Amanzi zokufunda emiselwe yi-avareji ye-pH.

Mineral uboya (GOST umisela ukuxhathisa lwamanzi angekho ngaphezulu kwe-4.7 pH) ngokufanelekileyo ukufunxa amanzi emthonjeni, ngaleyo ndlela alahlekelwe ezinye iimpawu zayo ubushushu-zokwambathisa ezikhoyo. Nangona kunjalo, izinga ukufuma ngokobunzima mayingagqithi-1%. Ukuphucula uzinzo ukuba ukufuma zokufunda buzane hydrophobizing okhethekileyo.

umphunga wamanzi permeability

Izinto eziluncedo ze kukho izinto ezifana noboya ezimbiwa, anokuquka kuquka ukukwazi ukuba ugqithe molecule yamanzi. Mineral uboya umphunga permeability lomlingani yi 480 * 10-6 g / (h * m * Pa). Xa kuthelekiswa nezinye Izifudumezi ezaziphila lelona liphezulu.

indawo ifayibha

Mineral uboya kunye ilungiselelo umbhodamo le imicu uba umxhuzulane ethile kwi 120-160 kg / ^m3 kunye namandla yokucazulula 10 kPa. Olu hlobo ngokuqhelekileyo yenziwa Iizilebhu ubude 120-160 cm kunye nobubanzi 50-60 cm. Abangelwe uboya kunye ilungiselelo nkqo Imisonto (ixesha) ubunzima ezahlukeneyo ezithile ka 80-120 kg / ^m3 kunye namandla iinyembezi 80 kPa e komsipha. Imilinganiselo macwecwe le ezahlukeneyo zezi 120 x 20 cm. Ububanzi uboya izimbiwa uyahluka 30-100 mm.

brand kakhulu ethandwayo

Ubukhulu becala eRashiya ngenxa zokwambathisa components isakhiwo esisetyenziselwa yezimbiwa uboya brand "Technonikol". Le mveliso livelisa kakhulu izinto ezikumgangatho ophezulu kunye nemigangatho kakhulu GOST. Ukongeza, loo nto ithathwa kubakho ingenelo ukuqina yeendleko eziphantsi.

Enye into ethandwa bezimbiwa Rockwool slab. Products kulo kumvelisi zingasetyenziswa usambathisa wobushushu of ngokupheleleyo naziphi na izinto ezakhayo kunye nezixhobo amandla. Abangelwe yoboya yale brand luyafumaneka kuzo zonke ubukhulu kunye iintsimbi.

Ububanzi bokusebenzisa

Iizilebhu kwezimbiwa wool elisetyenzisiwe usambathisa thermal:

• ndawo;
• olungaphambili umoya;
• olungaphambili lwendlu;
• uphahla;
• ngaphakathi iindonga nezinto;
• Uphahla;
• imibhobho;
• amaziko kunye itshimini;
• boilers;
• izixhobo yemveliso njalo njalo. d.

Mineral uboya - ukwambathisa esebenza kakhulu kwaye athembekile. Iindibaniso yokusebenza egqwesileyo kunye nexabiso eliphantsi kwenza ithandwa kakhulu phakathi abaphuhlisi ngamnye, ngokunjalo kwiinkampani ezinkulu mveliso.
