Yuav tsum muaj ib puag ncig ib puag ncig:
Roj av resins yuav tsum muab cia rau hauv ib qho zoo - pa ncho kom tiv thaiv kev ua kom pom kev los ntawm kev tshav ntuj, nag thiab kub.
Qhov ntsuas kub cia yuav tsum tau nyob nruab nrab ntawm 0℃thiab 40 degree. Thaum qhov kub me me qis dua 0 degree, ntxiv cov dej ntshiab, saturated ntsev dej mus rau cov cob rau kom tiv thaiv khov. Kev kub siab tau yooj yim tau yooj yim lub cob thiab nrawm nws qhov kev ua tsis ncaj, yog li nws yuav tsum muab khaws cia ntawm cov kub tsawg.
Muab ntim cia:
Roj av ua pov tseg muaj cov nplaim thiab yuav tsum tau ceev tseg ntawm cov chaw hluav taws.
Tag nrho cov kua polycesters muaj cov ntoo khaub lig xws li styrene, uas yog qhov yooj yim dua. Qhov kev sib xyaw tsis yog tsuas yog ua rau ib puag ncig tab sis kuj tseem tuaj yeem ua kom yooj yim rau kev tsis txaus ntseeg nyob rau hauv lub resin Cheebtsam, ua rau caping. Yog li ntawd, kaw cia yog qhov tseem ceeb.
Txee Lub Neej:
Cov ris roj av feem ntau muaj lub neej txee ntawm ib xyoos. Tom qab ib xyoos, lawv yuav tsum tau kuaj xyuas thiab, yog tias tseem siv tau, tuaj yeem siv dua.
Handling Tshwj Xeeb:
Yog hais tias lub resin tau ploj dej, tsis txhob ntxiv dej ncaj qha. Hloov chaw, tsau nws hauv qhov ntshiab, noo noo dej thiab tom qab ntawd maj mam dilute nws nrog dej ntxuav cov ntsev.
