Cov ntaub ntawv twg yog ua los ntawm lub tshuab khob ntawv? Cov ntaub ntawv twg yog lub khob khob tshuab ua los ntawm? Cov khoom siv sib xyaw ntawm lub khob khob tshuab suav nrog kev luam ntawv ncaj qha ntawm lub khob khob hauv paus ntawv, tuag-txiav, ua cov txheej txheem, thiab txau cov khoom noj ciab rau saum npoo. Cov txheej txheem tsim khoom ntawm lub khob haus dej kub yog txheej txheem ntawm laminating cov hauv paus ntawm daim ntawv khob rau hauv ntawv khob ntawv, luam ntawv, txiav txiav, thiab sib sau. Cov khob ntawv hauv paus ntawv yog tsim los ntawm cov ntoo cog, thiab nws cov txheej txheem tsim khoom feem ntau yog siv ntoo coniferous, tawv ntoo thiab lwm cov ntoo cog kom dhau los ntawm pawg thawj coj saib tom qab pulping, decomposing, refining, ntxiv cov khoom siv tshuaj lom neeg, tshuaj xyuas, papermaking thiab lwm yam. nyob rau
