Cov khoom siv tshuaj tseem ceeb siv hauv cov kav dej insulated yog cov khoom siv tshuaj lom neeg ntau yam uas ua rau cov txheej txheem rwb thaiv tsev thiab tiv thaiv.
Rwb thaiv tsev txheej Raw Materials (Rigid Polyurethane Foam):
1. Isocyanate (dub tivthaiv): Reacts nrog polyols los tsim cov qauv tseem ceeb ntawm cov npuas dej.
2. Polyether / Polyester (dawb tivthaiv): Lwm qhov tseem ceeb ntawm cov npuas dej.
3. Foaming tus neeg sawv cev: tsim cov pa roj thaum lub sij hawm cov tshuaj tiv thaiv, tsim cov npuas lub cellular qauv.
4. Catalyst: Tswj tus nqi ntawm foaming thiab gelation cov tshuaj tiv thaiv, ua kom cov txheej txheem ruaj khov thiab ua npuas ncauj zoo.
5. Surfactant / Foam stabilizer: Stabilizes cov npuas dej, ua rau cov qauv zoo thiab cov qauv ntawm tes.
6. Nplaim retardant: Txhim kho qhov hluav taws kub kev nyab xeeb ntawm cov txheej rwb thaiv tsev.
7. Crosslinking tus neeg saib xyuas / Chain extender: Txhim kho cov khoom siv hluav taws xob thiab kub ua haujlwm ntawm cov npuas dej.
Kev Tiv Thaiv Txheej Raw Khoom:
8. High-density polyethylene (HDPE): Ua haujlwm raws li cov txheej txheem tiv thaiv sab nrauv, muab cov dej tsis zoo, tiv thaiv corrosion, thiab kev tiv thaiv txhua yam.
9. Fiberglass, siv los ua cov rwb thaiv tsev lossis cov txheej txheem ntxiv rau ob peb qhov tshwj xeeb lossis siab - cov kav dej kub.
10. Lwm cov ntaub ntawv sheathing, muab tshuaj ntxiv lossis tiv thaiv hluav taws.
Cov khoom siv tshuaj lom neeg no, los ntawm kev tsim qauv thiab cov tshuaj tiv thaiv, ua ke tsim kom muaj zog, ua haujlwm tau zoo, thiab ruaj khov insulated piping system.
