Yuav ua li cas kom paub qhov txawv cov khoom yas raw

Vim lub limitation ntawm lub Hoobkas tej yam kev mob, kev tsom xam ntawm cov cuab yeej kuaj thiab tsis muaj, tsuas yog nrog rau cov tsos ntawm Vocabulary. Qhov kev txiav txim ua ntej ntawm cov khoom sib txawv los ntawm txoj kev sib xyaw, yuav tsum muaj kev paub thiab kev mus sij hawm ntev. Tab sis kuj muaj cov kev txwv, xws li ib lub workpiece los ntawm ntau cov ntaub ntawv, kom paub qhov zoo ntawm kev pom ntawm kev nyuaj, nws yog qhov nyuaj los qhia qhov combustion txoj kev los ntawm ntau yam combustion kom paub qhov txawv cov khoom ntim cov khoom, tsw.

Ntawm no yog ob peb txoj kev siv cov qauv ntawm cov khoom siv:

Cov qauv qhia txog kev tshwm sim

(a) PE, PP thiab PA muaj qhov sib txawv, txhais tes kov tawv nqaij zoo li creamy, thaum ntaus nrog lub suab mos mos. Piv nrog ABS, PC, PS, PMMA, thiab lwm yam., Tsis txuas ntxiv, txhais tes kov tau xwb ntaus lub cev, lub suab nrov.

(ob tug) qhov sib npaug ntawm PE thiab PP yog tsawg tshaj li 1, yog li nws ntws hauv dej, thiab feem ntau ntawm lwm yam yas yog ntau tshaj 1, yog li nws ntxuav hauv dej

(peb) hauv dyeing, LDPE yas hais, cov xim dawb ntawm pob mos, pob ntseg, mos thiab tawv, me ntsis elongated, yooj yim rau cov hniav deformation ntawm.HDPE yog dawb dawb, opaque, tawv zoo nkauj, lig extension, nrog rau cov hniav hu. PP deformable white translucent, siab transparency thiab PE sib dua, ntau nruj, nyuab nyuab heev rau tom hniav nrog cov hniav deformation.

(plaub) qhov txawv ntawm PS thiab HIPS thiab ABS yog PS HIPS thiab ABS yog brittle, zas, ces thaum nws khoov PS brittle. Ob qho tib si yog nyuaj rau ua txhaum, nyob rau hauv lub dabtsi yog khoov. Hauv qhov daj ua ntej dyeing yog yooj yim heev los txheeb xyuas; PS HIPS ABS pob tshab, xim dawb, xim daj ntseg.

Ob, kev soj ntsuam sib txuas

Cov khoom sib txawv muaj cov yeeb yam sib txawv ntawm combustion, xws li nplaim xim thiab tsis hnov tsw (nyob rau hauv cov txheej txheem ua haujlwm vim hais tias cov hluav taws kub degradation kuj yuav muaj ib lub txiaj ntsim ntawm cov yam ntxwv tsis zoo), cov qauv yooj yim uas yog siv cov ntaub ntawv pov thawj.
