Puas tseem muaj tus nqi rov ua dua rau cov log tsheb uas puas lawm? Cov lus teb yog muaj. Txawm hais tias cov log tsheb pov tseg no tsis haum rau kev siv hauv tsheb, cov roj hmab, hlau xaim thiab lwm yam khoom siv uas lawv siv tau.
Lub ntsiab tiv thaiv ntawm cov roj hmab, thiab txawm tias cov log tsheb puas ntsoog, cov roj hmab hauv lawv tseem muaj nqi. Roj Hmab Roj Hmab thiab Khoom Siv Hluav Taws Xob yog cov khoom siv hluav taws xob tseem ceeb rau cov log tsheb tsim rau cov log tsheb, thiab cov roj hmab cov ntaub ntawv pov tseg feem ntau ncav cuag 50% txog 70%. Tom qab cov roj hmab no tau rov ua dua tshiab, nws tuaj yeem rov ua haujlwm rau hauv roj hmab av vuas, roj hmab khiav, khau soles thiab lwm yam khoom. Noj cov roj av pem teb ua piv txwv, cov vuas hauv tsev ua los ntawm cov roj hmab rov muaj dua tshiab, cov nqi qis, thiab kev ua lag luam tsawg. Cov log tsheb hlau hlau: ntau lub log tsheb hlau sab hauv, tshwj xeeb tshaj yog cov xaim hluav taws xob rau ntau yam lag luam tshwj xeeb, thiab kev lag luam steel yog qhov chaw tsim khoom, thiab kev lag luam steel yog ruaj khov. Nws yog kwv yees tias qhov hnyav ntawm cov hlau xaim hauv cov log tsheb khib nyiab ntawm lub tsheb loj tuaj yeem ncav cuag ntau dua li kaum tus nqi rov qab.
Yog li, yuav ua li cas thiaj ua tiav qhov sib cais ntawm cov khib nyiab log roj hmab thiab hlau xaim? Qhov no yog qhov twg lub log tsheb tsoo los ntawm. Raws li lub npe qhia, cais cov roj hmab, hlau xaim thiab lwm yam khoom muaj nyob rau hauv lawv rau tom qab reprocessent. Lub log tsheb sib tsoo cov kab ntau lawm tsis yog ib daim yooj yim ntawm cov cuab yeej, tab sis ua tiav cov kab ua tiav ntawm ntau cov khoom siv. Ua ntej, cov log tsheb yog decomposed rau hauv 3-5 cm roj hmab thaiv thiab sib tsoo, thiab tom qab ntawd nkag mus rau cov roj hmab hmoov thiab txhaws cov capillary steel hlau thiab fiber ntau sib cais. Tag nrho cov kab ntau lawm tau khiav ntawm chav tsev kub, ua kom zoo nkauj, tsis muaj kev sib tsoo ntawm cov roj hmab xav tau (hloov cov khoom siv sib xyaw ua ke).
