I-1.Isetyenziswe kwizixhobo ezikhethekileyo, i-polyethylene yinto ehle kakhulu ekrwada, emva komlinganiselo othile, ingaba i-foam density efanelekileyo, isiphumo esihle sokugquma, ubunzima obuphezulu obuthwele izinto zokugquma ezibandayo. ukufunxa ukufuma, kodwa ngexabiso eliphezulu kancinane
I-2.Isakhiwo sokugcina i-thermal yokugcinwa kwe-thermal kufuneka ibe nokusebenza kakuhle kokufakelwa kwe-thermal, ukonga kwaye kunengqiqo, ifanelekile ekukhethweni kwezinto zokufakelwa kwe-thermal.Nangona kunjalo, ixabiso lokwakhiwa kokugcinwa okubandayo liphezulu, i-polystyrene ephezulu yokufunxa amanzi, ukufudumala ukufudumala, kodwa kuphantsi. endala original.Do indibano site, inzuzo kulwakhiwo olufanelekileyo, isantya ngokukhawuleza, mobile
3.Ukukhethwa kokugcinwa okubandayo kubaluleke kakhulu kwifriji, kuba ukugcinwa okubandayo kuhluke kwezinye iindawo zokugcina iimpahla.Khetha ipleyiti efanelekileyo yokugcina indawo ebandayo.Isakhiwo sebhodi yokugcina ebandayo kunye nokugcinwa okubandayo kwezonyango kufuna ukushisa okuphezulu, umswakama ophezulu. kunye nezinye iimfuno zokusingqongileyo.Ngoko ke, xa ukhetha ipaneli yegumbi elibandayo, kufuneka ihlawulwe ingqalelo kwizinto eziphathekayo kunye namandla okufakelwa kwepaneli.
Xa ukhetha izinto eziphathekayo, nceda uhlawule ngakumbi ubuninzi be-polyurethane kunye nobukhulu bentsimbi yensimbi.Ngokwemigangatho yelizwe, ukuxinana kwe-foaming yepaneli yokugcina ebandayo kungaphezulu kwe-40kg / m3. Ngoku kwiimarike, izinto eziphambili zezinto ezibonakalayo zebhodi yokugcina ebandayo yeprojekthi yokugcina ebandayo yi-polyphenylene, i-polyethylene kunye ne-polyphenylene grease.Ubuninzi bezinto zokufakelwa kwe-thermal ezifakwe i-polyphenylene zincinci, kwaye i-coefficient ye-thermal insulation ayiphezulu kakhulu;Emva komlinganiselo othile we-polyethylene, iyakwazi ukukhupha izinto zokugquma ezibandayo kunye noxinano olufanelekileyo kunye nesiphumo esihle sokufakelwa kwe-thermal, kwaye inomthwalo ophezulu wokuthwala;I-Polyphenylene resin inokufunxeka okuqinileyo kwamanzi, kodwa ubushushu obuphantsi.Ke ngoko, ibhodi yesangweji ye-polyurethane inomsebenzi ogqwesileyo.Nangona ixabiso liphezulu kancinci, ibhodi ye-polyurethane ineyona nto isebenzayo yokufakelwa kwe-thermal kwaye ayifunxa ukufuma.
