Cia peb pib nrog qhov tob saib ntawm ob qho kev xaiv.
NATURAL RUBBER yog dab tsi?
Cov roj hmab ntuj yog cov khoom siv roj hmab uas muaj nyob hauv qhov xwm txheej. Nws yog tsim los ntawm tapping ntoo, zoo ib yam li maple phoov, tsis yog los ntawm kev ua cov roj. Ntau tshaj 2,500 ntau hom ntoo tsim cov latex, tab sis feem ntau yog cov ntoo zoo nkauj hu ua roj hmab. Latex tshwm sim los ntawm tsob ntoo nyob rau hauv ib tug tuab, milky SAP uas yog ces ua tiav. Kev ua haujlwm feem ntau yog tshem tawm cov dej ntau dhau thiab tawm hauv cov roj hmab ntuj hauv cov pa luam yeeb lossis sab nraum zoov kom huab cua qhuav. Tom qab ntawd nws muab tso rau hauv bales thiab xa mus rau manufacturers.
Cov roj hmab ntuj hnub rov qab ntau txhiab xyoo rau kev vam meej zoo li Inca, leej twg yuav siv roj hmab los ua pob rau cov kis las qub. Tom qab ntawd, qhov kev poob qis tshaj plaws rau cov roj hmab ntuj yog tias nws yuav pib yaj los yog nplaum thaum qhov kub thiab txias heev. Nws tsis yog txog xyoo 1839 uas Charles Goodyear tau poob roj hmab ntawm lub qhov cub kub, tom qab ntawd mus rau patent txheej txheem ntawm vulcanization kom ruaj khov rau cov roj hmab zoo dua thiab ua kom nws tsis zoo.

SYNTHETIC RUBBER yog dab tsi?
Synthetic roj hmab, yooj yim muab, yog ib hom roj hmab uas tsis tuaj yeem muab cais ua cov roj hmab ntuj. Synthetic rubbers yog tsim los ntawm kev tsim cov polymers los ntawm kev daws teeb meem polymerization lossis emulsion polymerization.
Nrog ntau yam sib txawv ntawm cov roj hmab hluavtaws muaj nyob rau hauv kev ua lag luam, nws yog ib qho nyuaj rau generalize lawv tag nrho raws li ib qeb ntawm cov roj hmab uas zoo sib xws. Qhov feem ntau denominator yog tias lawv yog tag nrho cov byproducts ntawm roj. Tab sis kev sib txawv ntawm cov roj hmab hluavtaws txhais tau hais tias muaj ntau hom sib txawv yog tsim los ntawm cov qauv sib txawv, thiab txhua hom muaj cov khoom sib txawv tsim los ua kom haum rau cov ntawv sib txawv.
