Indlela ukukhetha usambathisa ekunene. Uluhlu conductivity thermal zezixhobo zokwakha

Imozulu kwiindawo ezininzi kwilizwe lethu zibi kakhulu. Kwaye ngenxa yokuba phantse yonke indlu eyakhiwe kweli lizwe oswele usambathisa. iintlobo ngeentlobo zezixhobo zingasetyenziswa nkqubo. Xa kukhethwa yokwambathisa kwi lokuqala ukunikela ingqalelo iqondo conductivity yayo thermal. I elisezantsi oko kukuthi, i-ngempumelelo ngakumbi sheathing. Ukuze ubone lo mzobo kukho kwitafile ekhethekileyo conductivity thermal zezixhobo zokwakha.

insulators amagwebu

Eli qela zemathiriyeli ngokwemiqathango ekulondolozweni ubushushu ithathwa ukuba ngcono. Kuye kwindawo yokuqala insulators ezifana istro amagwebu. Isniphu izinto zokwakha thermal itheyibhile conductivity ubonisa ngokucacileyo impumelelo yabo.

Jonga yemfaneleko insulators weqela nokuba abangoyikiyo ukufuma. Kodwa Ububi obukhulu kuzo zonke amagwebu kuthathwa ukuba singeke sikwazi ukudlula ngokwayo umphunga ibingenakunyakama. I izindlu amakhaya abo, ebizwa ngokuba ifuthe a thermos. Yaye ngenxa yoko, abanini kufuneka athathe amanyathelo ezongeziweyo ekuphuculeni isimo esendlini - ufake umoya kunye nenkqubo umoya. Kwakhona Ububi kwezi zinto ithathwa ukuba yokuba phantse ke musa ukulibala ingxolo. Ukongeza, insulators ugwebu babekuthanda kakhulu eyiva amabuzi kunye neempuku, abaqhuba ngayo ezi ndinyana. Kwaye oku, Kakade, kunegalelo ekugxojweni ingqibelelo wokufudumala ezikroziswayo nokunciphisa ukusebenza kwayo.

wool wokumbiwa

Le ntlobo yesibini uthandwayo insulators. Tshisa kwelo gumbi, unqanda mbi kancinane izinto amagwebu. Eli qela ibandakanya ubukhulu becala abangelwe noboya yeglasi. Izinto eziluncedo iphambili kolu hlobo Izifudumezi zithathwa ukuba ibe ngendleko ephantsi, kwakunye zomphunga elungileyo isandi usambathisa iimpawu. Bobubi zoboya izimbiwa ziquka ukukwazi layo ukufunxa ukufuma. Kwakhona Ububi kwezi zinto ithathwa ukuba yokuba wenze umphunga eyingozi nentlaka phenol-formaldehyde.

Yintoni efanele ukuqwalaselwa xa ukhetha i

Xa uthenga i yokwambathisa kwindawo yokuqala kufuneka sinikele ingqalelo parameter ezifana nezinyuko zayo. Kwakhona ngokuba ubushushu luncedo kwayo ngokwezalathi ezibalulekileyo kakhulu ezifana conductivity wobushushu zezixhobo zokwakha. Uluhlu neenqobo ezendeleyo iintlobo ezahlukeneyo insulators, ziza kuboniswa ngezantsi.

Ebubanzini wacela izinto kuxhomekeke kwizinto ezininzi:

• degree yayo conductivity thermal;

• zone kwemozulu;

• izinga conductivity thermal umbandela ziluvingcile nezakhiwo;

• udonga ubukhulu.

Ngokuba izindlu kumbindi weRashiya ngokwemigangatho babeka amalungiselelo maleko igqunyiwe olulingana kangangokuba ukukwazi layo ukugcina ubushushu yaba iyafana naleyo ababedume 1.5 yeemitha.

Kuba izakhiwo zomthi, eli nani kungaba ezincinane. Inyaniso yokuba imivalo kunye nomqadi ngokwabo kakuhle kakhulu ukugcina ubushushu.

Uluhlu conductivity thermal zezixhobo zokwakha

Ngoko ke, yintoni iimpawu kule nkalo eyahlukileyo okanye i yokwambathisa? kakuhle indlela izinto zokwakha zale mihla le ezahlukeneyo ukugcina ubushushu, zingafumaneka kule theyibhile.

Table conductivity thermal zezixhobo zokwakha, ngaloo ndlela ebonisa ukuba ubushushu kakhulu ngempumelelo kwi okwangoku ezinepolisterini. Wool, njengokuba sele kukhankanyiwe, uyakwazi ukulibazisa abandayo kancinci kakhulu.

Indlela ukukhetha izinto

Ngaloo ndlela, nto leyo ebaluleke kakhulu impumelelo ke ubushushu lwesakhiwo imvulophu na conductivity wobushushu zezixhobo zokwakha. Le theyibhile, Kakade - asiyiyo yodwa indlela ukwazi inombolo yakhe. The degree of conductivity thermal le yokwambathisa kudla kuboniswe kuyo umenzi. Amaxabiso alandelayo ukuphawulwa kwiilebhile:

• degree of conductivity thermal kwindawo eyomileyo kubushushu kwe-10 ^{° C;}

• kwindawo eyomileyo ^kwi-25 ° C;

• kwiimeko ukufuma ezahlukeneyo (A okanye B).

Kunye amagwebu, noboya ngokubanzi ziveliswa okusuka we-10 okanye 5 cm. Njengoko kwitafile lothelekiso ebonisa conductivity wobushushu zezixhobo zokwakha, iRashiya umaleko Izakhiwo amatye engundoqo zigqunyiwe kufuneka bungabi ngaphantsi kwe-12-13 cm. Noko ke, xa kusenziwa, ngokuqhelekileyo kwanele kunye-10 cm. ngoko ukwahlukanisa suburban zisebenza izakhiwo okanye umaleko ube mnye izinto-10 cm, okanye yokwambathisa ezimbini-5 cm zamafu. Indlela yokugqibela lisetyenziswe ngokufuthi. Ngesi bugcisa, umaleko yesibini ilele ukuze amalungu okuqala yayivalekile ngokupheleleyo. Isiphumo esiphezulu uphawu lunenwebu ukufudumala.

Materials bekujongiwe bodwa izindlu lizwe, ngexesha lethu, njengokuba ubona, zininzi. Ukuba oyifunayo, ezisongwayo inokufunyanwa njengoko lobeko isiponji uboya bezimbiwa. Isiphumo njengoko theyibhile ibonisa conductivity wobushushu zokwakha, yaye ngaloo kwaye kwezinye imeko iya kuba iyamangalisa. Kakade ke, nangona kunjalo, kuphela xa walling lining iya kuba olulingana ngokwaneleyo.
