Hauv cov caij nyoog niaj hnub no, nws tsis tshua muaj qhov kho vaj tse ua tsis muaj kev tiv thaiv hluav taws xob. Qhov teeb meem ntawm qhov chaw txuag hluav taws xob ntawm ib theem ntawm cov nqi hluav taws xob nqi yog ib qho nyiaj. Hais txog lub ntsiab ntawm cov cua sov thiab lawv cov yeeb yam, peb mam li tham hauv no tsab xov xwm.
Tag nrho cov ntaub ntawv siv rau kev kho vaj tse yuav tsum muaj raws li cov qauv kev ruaj ntseg tshwj xeeb. Mus rau lub rwb thaiv tsev rau ntawm phab ntsa yog hauv qab no:
- hluav taws kev nyab xeeb;
- durability;
- thermal conductivity tsawg;
- tsis muaj deformation;
- ecological compatibility;
- ya raws kuj.
Hom kev rwb thaiv tsev thiab cov yam ntxwv
Txhua hom kev tiv thaiv rau phab ntsa ntawm sab hauv yuav muab faib ua ob pawg loj:
- reflecting - tiv thaiv cov teeb ntais sab hauv;
- tiv thaiv - khaws hluav taws xob vim muaj cov thermal conductivity ntawm insulating cov ntaub ntawv.
Feem ntau, cov ntaub ntawv ntawm hom thib ob yog siv, lawv tig tau faib ua cov organic thiab tsis muaj dej. Ntawm chav kawm, nws yog qhov zoo dua los siv hluav taws xob rwb thaiv tsev hauv tsev.
Cov hom kev ua kom dej sov muaj xws li:
- ntxhia yaj ywm, uas ua los ntawm cov khoom siv hlau hauv av thiab cov basalt;
- npuas polyvinylchloride thaiv (PPVH) - yog tsim los ntawm polyvinyl chloride resins los ntawm porphyring;
- chipboard (particleboard) - yog cov ntoo khib nyiab los sis txiav cov pob kws thiab lwm cov qoob loo.
- Polyurethane ua npuas ncauj rwb, muaj polyester, dej, emulsifier thiab diisocyanate;
- Arbolitovye rwb thaiv tsev - tsim los ntawm ntoo pov tseg.
Qhov no tsis yog tag nrho cov npe ntawm cov khoom cua sov . Txhua xyoo lawv tus lej nce tuaj, thiab qhov zoo dua qub. Cov lus nug, hom cua sov yog dab tsi, nws yog qhov zoo tshaj plaws los nug ncaj qha ua ntej kev kho , kom paub txog tag nrho cov kev nrhav hauv kev tsim kho kev lag luam.
