Nyob rau hauv xyoo tas los, los ntawm lub teb chaws mus rau tus kheej, kev paub txog kev tiv thaiv ib puag ncig muaj kev txhawb nqa, thiab kev siv cov khoom siv ib puag ncig tau dhau los ua lub hom phiaj. Kev tiv thaiv ib puag ncig ntsuab tsis yog tsuas yog cov lus hais. Nws tau dhau los ua ib txoj cai tswjfwm los ntawm kev siv niaj hnub no. Kev tsim kho cov kav dej kuj tseem yog ib qho ntawm cov khoom siv tseem ceeb. Nws paub los ntawm cov chaw tsim kho hauv ntau lub xeev thiab nroog hais tias kev tiv thaiv ib puag ncig yog tam sim no tshwj xeeb nruj, thiab kev tiv thaiv ib puag ncig thiab kev saib xyuas cov khoom siv kev tsim kho yog sib zog heev.
Kangyu yeeb nkab kev lag luam PB yeeb nkab siv, uas yog ntsuab thiab haum rau cov kav dej xa dej thiab cov kav dej hauv pem teb.
Qhov txiaj ntsig ntau ntawm PB yeeb nkab tsuas yog teev:
1, qhov kub thiab txias tsis kam, tuaj yeem tiv taus siab kub qis dua 110 degrees, -20 degrees yuav tsis khov thiab tawg
2. Nyias cov yeeb nkab phab ntsa, lub taub loj diam, ua kom dej ntws zoo
3.Qhov txuas ntxiv ntawm micro-nkag thiab zoo thermal nthuav tawm thiab cov ntawv cog lus yog qhov txaus siab rau cov raj xa dej
4. Lub zog UV tsis kam tiv thaiv, tiv thaiv algae ntau lawm
5, zoo plasticity, pab rau kev tsim kho
6, lub teeb heev hnyav, yooj yim rau kev daws
7, ib puag ncig zoo rau kev siv hluav taws xob, tsis muaj tshuaj lom thiab tsis qab, tsis muaj tshuaj lom thiab tsis muaj tshuaj lom tom qab kev sib xyaw.
