Cov khoom siv ntawm cov ntawv tawv nqaij yog tsuas yog ntawv. Daim ntawv teeb liab yog ua los ntawm cov ntawv txheeb xyuas cov ntawv, uas tuaj yeem yog ib qho decomposed nyob rau hauv ib lub sij hawm ntawm lub sij hawm, ua kom muaj kev cuam tshuam rau ib puag ncig. Txawm li cas los xij, cov khaub ncaws ua ib txwm muaj qee yam teeb meem thaum siv, yooj yim softening thiab stratification tom qab soaking hauv dej, ua rau tus neeg siv tsis zoo.
Txhawm rau txhim kho cov teeb meem no, cov kws tshawb fawb tau tsim cov hom tshiab ib puag ncig tus phooj ywg. Cov quav cab no yog tsim los ntawm kev ntxiv me me ntawm cellulose ntawm cov khoom siv nanocrystals los ua cov txheej txheej kom zoo rau synthesize yas-polybutylene succinate succinate succinate succinate succinate succinate succinate succinate succinate succinate succinate succinate succinate succinate succinate succinate succinate succinate succinate succinate succinate succinate succinate succinate succinate succinate succinate succinate succinate succinate succinate succinate succinate succinate succinate succinate succinate succinate succinate succinate succinate succinate succinate. Cov khoom txheej txheej no tuaj yeem txuas nrog rau saum npoo ntawm daim ntawv, ua rau cov khaub ncaws tsis yooj yim kom tau ntub thiab muaj peev xwm nyob twj ywm hauv ob qho dej txias thiab dej qab zib. Txawm tias thaum sib cuag nrog kua rau lub sijhawm ntev, cov quav cab yuav tsis tau ntub lossis khoov.
Tsis tas li ntawd, tus nqi ntawm cov khaub ncaws sau yog qhov tseem ceeb, thiab tus nqi tsim yog ntau dua ob zaug ntawm cov khaub noom yas. Tus nqi ntawm cov hnab yas yas yog li ntawm 3 xees, thaum tus nqi ntawm cov khaub ncaws sau yog siab li 10 xees.
