Ka bobeliLiphanele tsa PIRleliphanele tsa polokelo e batangsheba thepa ea ho thibela mocheso e sebetsang hantle. Phapang e kholo e holim'a thepa le khatiso ea ts'ebetso: Liphanele tsa PIR (liphanele tsa polyisocyanurate) ke ntlafatso e tsoetseng pele ea polyurethane (PUR), li na le ho lieha ho hoholo ha malakabe, ho hanyetsa mocheso o phahameng (ho fihlela ho 200℃ le ho feta), le ho monya mongobo o tlase (ho tlase haholo ho feta PUR). Ke khetho ea pele bakeng sa ho haha libaka tsa polokelo ea serame tse hlokang tlhokomelo e phahameng, lifeme tsa ts'ebetso ea lijo le mehaho e meng. "Liphanele tsa polokelo ea serame" ka kakaretso li bua ka thepa ea ho thibela mocheso e sebelisoang polokelong e batang, e ka bang PIR, PUR, XPS, jj. Ka lebaka la ts'ebetso ea eona e felletseng, PIR e fetohile karolo ea mantlha ea lisebelisoa tsa sejoale-joale tse phahameng.diphanele tsa polokelo e batang.
Litšobotsi tsa Boto ea PIR (Polyisocyanurate):
Khanyetso e Phahameng ea Mollo: Ka ho eketsa bongata ba lesale la isocyanate, khanyetso ea eona ea mollo e feta hōle ea phanele e tloaelehileng ea PUR, e fihlella tekanyo ea mollo ea B1.
Ho Sireletsa ka Mocheso ka Botlalo: Ho tsamaisa mocheso ka tlase haholo (≤0.023 W/mK), ho fellang ka bokgoni bo phahameng ba ho thibela mocheso.
Khanyetso ea Mocheso o Phahameng: Tšebeliso ea nako e telele e ka mamella mocheso o kaholimo ho 150℃, esita le ho fihlela ho 205℃, e loketse libaka tse nang le mocheso o phahameng.
Ho Monya Metsi a Tlase: Sekhahla se tlase haholo sa ho monya metsi, se thibela ho kena ha mongobo ka katleho le ho boloka ts'ebetso ea ho futhumatsa.
Matla a Phahameng: Ho ba le sekgahla se phahameng, sebopeho se tsitsitseng, ho matlafatsa matla a moaho.
E Sireletsa Tikoloho: Ha e na CFC.
Liphanele tsa polokelo e batang:
Khopolo-taba e Akaretsang: E bua ka diphanele tsohle tsa sandwich tse sebediswang kahong ya dibaka tsa polokelo tse batang; mosebetsi wa mantlha ke ho kenya mocheso le ho kwala.
Lisebelisoa tse Fapaneng: Ntle le boto ea PIR e tloaelehileng, e boetse e kenyelletsa PUR (polyurethane), XPS (polystyrene e ntšitsoeng), jj.
Tsepamiso ea Tshebetso: Lisebelisoa tse fapaneng tsa mantlha li khethoa ho latela litlhoko tsa mocheso oa polokelo e batang.
Liphanele tsa PIR khahlanong le Liphanele tse Tloaelehileng tsa Polokelo ea Cold ea PUR
Khanyetso ea Mollo: PIR > PUR
Khanyetso ea Mocheso: PIR (-196℃ + 205℃) > PUR (-185℃ + 110℃)
Ho Monya Metsi: PIR (<1%)< PUR (2.5%~3%)
Botenya: PIR (40-45 kg/m³) > PUR (38-40 kg/m³)
Theko: PIR ka kakaretso e phahame ho feta PUR.
Kakaretso
Liphanele tsa PIR li emela liphanele tsa polokelo ea serame tse sebetsang hantle haholo, haholo-holo tse loketseng indasteri ea sejoale-joale ea thepa ea ketane ea serame le ea ts'ebetso ea lijo tse nang le litlhoko tse thata tsa ho hanyetsa mollo, ho hanyetsa mocheso o phahameng, le ho monya mongobo o tlase. Li fana ka tharollo ea ho thibela mocheso e sireletsehileng le e tšepahalang haholoanyane ho feta liphanele tsa kamore ea serame ea PU ea setso.
