Amagwebu usambathisa. Iimpawu, ubukhulu, ixabiso

Gas-ezaliswe zeplastikhi, emele izinto olungaphandle iiseli amagwebu, kwakucingwa ukuba udidi amagwebu. Kuxhomekeka ubugcisa bemveliso kunye Polymer isicelo, kule klasi ziquka iindidi ezininzi izinto eziye kwiinkalo ezahlukeneyo isicelo. Bonke babe iipropati ubushushu ubuthi. I ethandwayo amagwebu ngaphambili usambathisa PSB-S-25 uyahlangabezana neemfuneko azinantsholongwane kwaye isiseko jikelele naluphi na uhlobo isamente.

Overview

Ngenxa yokwanda iindleko zamandla ingxaki ongxamisekileyo ukukhusela walling kwizakhiwo nxamnye ukukhululwa elingenzi nto ubushushu ngaphandle. Ukuxinana phantsi izinto amagwebu inika ukusebenza eliphezulu usambathisa thermal. Ngoko olungaphambili Ukwambathisa amagwebu yi isisombululo zaphambili yokonga amandla. Nangona le nto kummandla kuphela kulo mbandela.

Iyasetyenziswa:

• njengokuba izitya lokufaka amagumbi, ebenza yayingenakuzika;
• ekwenziweni needyasi ubomi, buoys kunye eYafo;
• njenge material ekuveliseni tar zonyango, ezisetyenziswa ukuthutha amalungu ukunikela;
• njengoko ukhuseleko impahla ezibuthathaka;
• njengoko yokwambathisa oshushu kwizikhenkcisi kunye nezinye izixhobo zasekhaya.

iintlobo ekwambathiseni thermal

Kukho manani, nayiphi na imigaqo nto kuqinisekiswa ukuba ilahleko ubushushu ngaphaya kweendonga ukuya kwi-40% ngophahla - 25%. Ngoko ke, ukuba nkulu ukukhuselwa kwepropati ukusuka ufudumele ngokusebenzisa ukwambathisa iindonga kunokwenzeka.

Womvalela egumbini ukusuka ukungena ukufuma kunye umoya obandayo nokungena ngeendlela ezimbini: ngaphandle ngaphakathi. Kukholelwa ukuba ukukhusela udonga ngumkhenkce lo gama kugcinwe indawo lwangaphakathi izindlu, xa usambathisa lwangaphandle. Kwaye enye inzuzo olungaphambili wesakhiwo ukukhusela - kukuba phakathi ubushushu ngaphakathi kwaye udonga nokuxhasa ezikhandelwa zone amafu. Nguwo lowo bume efanelekileyo yophuhliso sande nangesihumba. Kwaye loo nto ayakhuselwa udonga ngaphandle igcina ubushushu elide kwaye zipholile.

Nangona kukho iimeko, umzekelo kwimeko indlu yomhombiso ezintle okanye ikheshi xa ubushushu njengogwebu ngaphandle senziwe ngendlela akunakwenzeka. Emva koko sebenzisa iindonga self-ukhuselo. Ukongeza alephuze amagwebu, abakhi ukusebenzisa ezinye izinto.

iindidi zezixhobo

ukwambathisa Popular: uboya ezimbiwa, istro esandisiweyo lyu amagwebu. uboya Mineral ifakwe kuphela kwi ifreyim yesinyithi, nto leyo ke kufuneka sheathing iibhodi gypsum, ujike okanye ezinye izinto iphele. Lyu amagwebu umntu inzuzo zexeshana njengoko isicelo ngendlela oluzenzekelayo, ngenxa wokutshiza. Xa izinto izalisa nditshaye kwisakhelo, ekusekeni ukutyabeka monolithic. Noko ke, ukukhusela iindonga ngendlela indleko ngaphezu alephuze amagwebu esetyenziswayo usambathisa.

Istro amagwebu yenziwa ngeendlela ezimbini, apho kukho bespressovanny kunye ebumbeneyo. Ukuchongwa kwe PS-1 sithetha ukuba cinezela lokuvelisa alephuze amagwebu tile, kunye PSB-S - a eziphathekayo kunye namandla self-mlilo. Oko kukuthi, xa umenzi wayo usebenzisa istro kunye ekuncipheni LINGATSHA.

iimpawu qualitative

Olungaphambili Ukwambathisa amagwebu luqala ukhetho izinto. Ezona mpawu ziphambili ukuba kufuneka ukuba uyazi, ukuthenga isifudumezi - oko ubungakanani iipleyiti, lexinene ubukhulu. Ngokutsho GOST 15588-86 nemilinganiselo wesiqhelo Iizilebhu ingaba:

• Ebubanzini ngo-10 mm: 20-500 mm;
• ngokwemizuzu ubude-50 mm 900-5000 mm;
• ububanzi ngokwemizuzu ka-50 mm 500-1300 mm.

Kodwa ukuba ngesivumelwano phambi ukuvelisa iibhodi ngobukhulu engekho semgangathweni. Iiplanga amagwebu enziwa izikhombisi lexinene zilandelayo: 15, 25, 35 no-50 kg / m ^3. I elikhulu le Isalathisi, ngokuqina eziphathekayo ngezantsi namandla layo ukufunxa ukufuma. Sheet ne mninzi 35 kg / m3 50 mm ubukhulu iyafana kwizakhiwo zazo physicochemical umbandela kunye ukuxinana 25 kg / ^m3 kunye ubukhulu ka-100 mm. Nangona kunjalo, ixabiso le alephuze amagwebu uphakame, ayanda lexinene usambathisa.

Ukukhetha esinobukhulu oluthile ukwambathisa kuyimfuneko ukuqwalasela eziliqela ze wenze ubalo olulula.

Ukukhethwa Ebubanzini elichanekileyo lezinto

Ububanzi ubushushu kuxhomekeke uxhathiso ubushushu transfer iindonga ezingaphandle ezilawulayo, eziye njalo ukuba imozulu ezahlukeneyo, kwaye Ebubanzini ezindongeni izinto zokwakha.

Ngokomzekelo, ubuncinane ukumelana avumelekile thermal kweendonga St. Petersburg yi 3,08 m ² * K / V. Kukho indlu yezitena, ogama iindonga zakhiwa enye enesiqingatha izitena ceramic vuphukuphuku. ukumelana nobushushu a wokwakha 1.06 m ² x R / W. Kufuneka ukuba ubale kanjani zamafu ukuba amagwebu usambathisa.

Ukuphumeza ixabiso 3,08 kuyimfuneko ukufumana umahluko phakathi uxhathiso thermal kunye nemigaqo ekhoyo: 3,08-1,06 = 2,02 m ² x R / W. Oko kukuthi, ixabiso Waziwa, ekufuneka abe amagwebu. Zokuvala DPM-25 super umntu conductivity thermal (ngokuhambelana GOST) 0.039 W / (m · K).

Ngokusekelwe ifomula ukuba uxhathiso thermal i ubukhulu ethile umaleko on the conductivity wobushushu ngayo umbandela, siye :. 2.02 * 0.039 = 0.078 m Kulo mzekelo, i alephuze amagwebu awazuze DPM-25 80 mm ubukhulu. Ekubeni yokubala elolo hlobo akuthethi ithathele ingqalelo uxhathiso wobushushu ye umaleko udaka, nto leyo eye zombini ngaphakathi nangaphandle kwesakhiwo. Ngoko ke, eneneni, iimfuno alephuze amagwebu ububanzi kuya kuba ngaphantsi kwe-80 mm.

Yintoni enye ngerabha amagwebu?

Ngenxa inani eliphantsi nokufunxwa kwamanzi zokufunda isoloko isetyenziswa kwiindawo eziphakamileyo ukufuma. Sheets ugwebu walala lwesakhiwo sesiseko, ukuze asetyenziswe ekwakheni izindlu bezpodvalnyh.

kucetyiswa ukuba babeke imbawula lobusi kwi inxalenye othe tye kunye nkqo ukwenzela ukuthintela ukuqanda isiseko sendlu. Njengoko Ukwambathisa amagwebu isandi nga ulalisiwe eludongeni dummy phakathi amagumbi. Usambathisa emhlabeni yonke imigangatho, balcony, loggias kunye styrofoam kusetyenziswa. Ukongeza yokukhusela izakhiwo ekulahlekelweni ubushushu, izinto ezisetyenziswa kwiinkqubo ifriji.

Iindleko ugwebu zeplastiki

Eli candelo lichaza iindleko iklasi ubushushu ugwebu kwi kwamaxabiso Novemba 2015.

istro eYandisiweyo akhiwe extrusion, ebizwa PENOPLEKS. Ezi iibhodi eqinile ngaphezu amagwebu, yaye ixabiso labo iphezulu kakhulu. Iindleko ipleyiti enye (1200h600h50 mm) yi engange 183, ngokusekelwe 1 m ³ 5080 engange.

On Web site ethengisa Izifudumezi ezinjalo igama efanayo imveliso njenge amagwebu-50 mm. Le izinto sheet aqhelekileyo kunye imilinganiso 1000h2000 mm. Ixabiso ipleyiti enye - 180 engange. Ke kaloku, xa kuthelekiswa Penoplex ibonisa ukuba eqhelekileyo cube alephuze amagwebu-50 mm ubukhulu, exabisa engange-1800, yaye oku 3200 engange zitshiphu istro extruded.

Ngoko ke, ukuba amagaqa amagwebu kunesiqhelo, ngokuxhomekeke lexinene, kuyimfuneko:

• PSB-C15 - 2160 engange;
• PSB-C25 - 2850 engange;
• PSB-C35 - 4479 engange;
• PSB-C50 - 6699 engange.

Iintsomi malunga amagwebu usambathisa okuyingozi

Eyokuqala edibene kusungulwe "iindonga yokuphefumla" usungule kota. Kukho ingcebiso yokuba ipropati amagwebu ubushushu unciphisa kwii-umphunga wamanzi, ngaloo ndlela ziyonakala microclimate ibunjiwe nokufuma phezulu ngaphakathi. Isakhiwo ayikho elithi "udonga zokuphefumla", kunye yimisinga umphunga wamanzi, nto leyo eneneni kujikeleziswa phakathi ezitalato kunye nendlu ngodonga, encinane kakhulu. Ukwenziwa nokuvunda kwaye zokrazulwa kwigumbi emva amagwebu ubushushu beendonga - njengesiphumo moya kakuhle.

Intsomi yesibini - oko ngokwakokusingqongileyo izinto lula. istro eYandisiweyo ibhekisa izinto ngaphandle iikhemikhali eziyingozi. It iqulathe 98% zezulu, no-2% ezinepolisterini. Akanalo yemisebe kwaye phantsi ukusetyenziswa 100%. lobushushu zokusebenza: -200 ... + 80 degrees. Ke EPS ubethwa acetone, benzene, ngoko xa ukhetha mibala ndiwufezile olungaphambili kufuneka ingqalelo le nto.
