Ukwakhiwa kwe-insulation yophahla lwangaphakathi udonga kunye nodonga lwangaphandle Izixhobo ze-polyurethane zokugquma izixhobo

Zeziphi iinqobo zokwamkelwa zokugqunywa eludongeni lwangaphandle?

Ukwamkelwa kokwakhiwa kodonga lwangaphandle kunokwahlulwa kwizinto eziphambili zokulawula kunye nezinto eziqhelekileyo.Iindlela zokwamkelwa kunye nemigangatho yile ilandelayo:

Izinto eziphambili zokulawula izixhobo ze-polyurethane zokugquma uphahla lwangaphakathi kunye nokwakhiwa kodonga lwangaphandle

Izinto ezisetyenziswa kwinkqubo yokugquma kufuneka zihlangabezane neemfuno zoyilo kunye nemimiselo echaphazelekayo yalo mmiselo.

Ubume kunye neenkcukacha ze-thermal insulation system ye-thickness of polyurethane izixhobo zokugquma ibhodi yokugquma udonga lwangaphandle ekwakhiweni kwesakhiwo kufuneka zihlangabezane neemfuno zokwakha uyilo lokugcina amandla.Ukuphambuka okuvumelekileyo kobunzima bomgangatho wokufakelwa (ubukhulu boyilo) ngu +0.1, kwaye umgca we-insulation kufuneka uhlanganiswe ngokuqinileyo eludongeni.I-glue yokutyabeka kunye nebhodi ye-insulation kufuneka idibaniswe ngokuqinileyo, kwaye i-surface layer ayinazo iziphene ezifana nomlotha kunye neentanda.

ImiQathango Jikelele yeMathiriyeli yokugquma iPolyurethane kunye neSixhobo soDonga lwangaPhakathi lweDonga kunye noLwakhiwo lwaNgaphandle lwe-Insulation.

1. Umnatha omelana nealkali kufuneka udityaniswe, ububanzi obuthe kratya abufanele bube ngaphantsi kwe-100mm, kwaye umnatha omelana nealkali kufuneka uqiniswe.Ukuziqhelanisa kufuneka kuhambelane neemfuno zoyilo.

2. Umphezulu we-insulating layer kunye ne-plastering layer kufuneka ibe tyaba kwaye icoceke, kwaye iikona zomgca kufuneka ziqonde kwaye zicace.

3. Nika ingqalelo ekuphambukeni okuvumelekileyo kofakelo lwebhodi yokufakelwa kunye nokuphambuka okuvumelekileyo komgangatho wokutyabeka.

Ngexesha lokucutshungulwa kunye nokusetyenziswa kwezixhobo zokutshiza ze-polyurethane, nokuba yinqwelomoya okanye umphezulu ongaphezulu, nokuba isangqa okanye ingqukuva, okanye ezinye izinto ezintsonkothileyo, inokutshizwa ngokuthe ngqo, kunye nezixhobo zokufakelwa kwe-polyurethane kuphahla lwangaphakathi. udonga kunye nolwakhiwo lwe-insulation eludongeni lwangaphandle lunokwenziwa ngokuthe ngqo.Naziphi na iindleko ezibizayo zokuvelisa.I-polyurethane yokugquma isitshizi sodonga lwangaphandle ngokwayo inoluhlu lwe-insulation layers, kwaye imilo yayo ngokusisiseko ikuluhlu olufanayo nolo lwezinye izinto, kwaye akukho mthungo konke konke xa ifafaziwe.Kunokuthiwa impembelelo yabo yokugquma ilungile kakhulu, kwaye kukho nolusu oluhle kakhulu lwesikhumba kuluhlu lwangaphandle, olunokukhusela kakuhle izinto zangaphakathi.

Iprojekthi yolwakhiwo lobunjineli bokufakelwa kodonga lwangaphandle lwesakhiwo yenze ukuba indlu iwuqonde umsebenzi wokuba shushu ebusika kwaye kuphole ehlotyeni.I-polyurethane yokutshiza i-insulation wall yangaphandle lishishini elinesiqinisekiso sokwakhiwa kwe-insulation yesibini.Ibonelele ngeenkonzo zokwakha ubunjineli bodonga lwangaphandle kwizakhiwo ezininzi, kwaye inethemba lokuba negalelo kuphuhliso lwabantu.

Ngoku, ngenxa yophuhliso oluqhubekayo lwezoqoqosho, inani lezakhiwo zesi sixeko liyaqhubeka lisanda, yaye urhulumente ukwakhuphe uxwebhu olufuna ukufakwa kweendonga zangaphandle kuzo zonke izakhiwo ezitsha.EShanghai nakwezinye izixeko eziphuhlileyo kwezoqoqosho, urhulumente ukwafuna ngokulandelelana izakhiwo esele zikhona ukuba ziqhube uhlaziyo lokonga umbane kwiindonga zangaphandle ukukhuthaza ukongiwa kwamandla kunye nokunciphisa ukukhutshwa kombane.Kwiindawo ezisemaphandleni, ubunjineli bokufakelwa kodonga lwangaphandle bukwasetyenziswe ngamandla, kwaye ngoku uninzi lweendawo ezisanda kwakhiwa ezidolophini okanye iivillas zasemaphandleni zisebenzisa ukugquma kwangaphandle eludongeni.
