Qhov sib txawv tseem ceeb ntawm cov resin thiab yas yog tias cov resins muaj ntau lub hauv paus chiv keeb vim peb tsim lawv ncaj qha los ntawm cov nroj tsuag oozes whereas cov yas yog cov hluavtaws polymeric xwm.
Resin thiab yas yog cov organic xwm, uas feem ntau muaj cov saw hlau ntev hydrocarbon. Vim muaj qhov rov ua dua tshiab, ob qho tib si muaj cov yam ntxwv ntawm polymer. Txawm li cas los xij, thaum cov resins muaj ntau dua ntawm cov qauv ntuj, cov yas feem ntau yog hluavtaws lossis semi-synthetic hauv xwm.
Resin yog dab tsi?
Tau ntau xyoo, tib neeg tau siv cov resins hauv ntau daim ntawv thov. Piv txwv li, txhawm rau kaw nkoj, mummies, ntim khoom noj thiab lwm yam. Tsis tas li ntawd, resins ua ib feem ntawm cov kua roj vanish, lacquer, jewellery, naj hoom, thiab inks. Tab sis, hais lus los ntawm kev xav ntawm cov tshuaj, peb tuaj yeem categorize resins raws li ib pawg ntawm cov khoom los yog semi-solid amorphous compounds. Peb tuaj yeem tau txais qhov sib xyaw no ncaj qha los ntawm cov nroj tsuag ua exudations. Tsis tas li ntawd, lawv feem ntau muaj cov xim daj daj daj thiab yog cov khoom muaj kuab heev uas ua rau cov pob tshab pob tshab nrog kev kho mob. Tsis tas li ntawd, lawv feem ntau muaj cov kua terpenes tsis hloov pauv thiab tsawg dua ntawm cov khoom tawg uas tsis yog-volatile uas ua rau cov resins nplaum (gluey) thiab tuab. Bicyclic terpenes yog hom terpenes ntau tshaj plaws uas peb tuaj yeem pom hauv cov resins.

Txawm li cas los xij, nrog kev nce qib hauv thev naus laus zis, txoj hauv kev tshiab tau siv los tsim cov resins rau hauv cov khoom siv polymers. Yog li ntawd, hluavtaws resins sai sai tau los ua. Synthetic resins feem ntau ruaj khov, kwv yees tau thiab muaj tus cwj pwm zoo txij li peb tsim lawv raws li kev tswj xyuas. Tsis tas li ntawd, vim muaj kev tswj xyuas, qhov ua tau ntawm kev taw qhia ntawm impurities yog tsawg. Ntxiv mus, lawv feem ntau pheej yig dua thiab yooj yim dua los kho dua.
YPlastic yog dab tsi?
Peb tuaj yeem faib cov yas dav dav raws li hom hluavtaws cob. Tab sis, ntau yog lawv yog hluavtaws los yog semi-synthetic organic polymers ntawm siab molecular loj uas yog mouldable. Feem ntau, plastics yog muab los ntawm petrochemicals. Yog li ntawd, feem ntau ntawm lawv nyob ib nrab ntawm ntuj. Txawm li cas los xij, muaj cov plastics ntshiab huv hauv cov cim, thiab peb hu lawv ua bioplastics vim peb feem ntau tsim lawv los ntawm cov khoom siv cog dua tshiab.
Ntxiv mus, cov yas ua cov polymers ntawm hydrocarbons kuj muaj lwm yam xws li oxygen, sulphur, nitrogen thiab halogens. Feem ntau, peb ntxiv lwm cov organic thiab inorganic additives rau plastics, los txhim kho lawv cov khoom thiab xim. Piv txwv li, siv cov yas yas los txo qhov rigidity ntawm cov yas.

Peb tuaj yeem faib cov yas hauv ntau hom vim nws cov tshuaj lom neeg thiab cov qauv. Lawv yog acrylics, silicones, polyesters, polyurethanes thiab halogenated yas.
Qee yam khoom tshwj xeeb ntawm cov yas yog raws li hauv qab no.
- Hard
- Dense
- tiv tshav kub
- oxidation
- ionizing hluav taws xob thiab cov kuab tshuaj organic.
Xav txog lawv cov kev siv, kev siv cov yas yog dav heev uas peb tuaj yeem pom lawv hauv cov ntawv clips, fwj, textiles, rooj tog, ntim khoom noj, fibers, tsheb thiab lwm yam. Vim yog cov khoom zoo ntawm cov yas, peb tuaj yeem siv. lawv hloov ntau lwm yam ntaub ntawv uas muaj txiaj ntsig zoo yav dhau los xws li ntoo, iav, hlau, ceramics, tawv, ntawv thiab lwm yam. Qee hom yas yog polythene, Bakelite, PVC (Polyvinyl chloride) thiab Nylons.
Qhov txawv ntawm Resin thiab yas yog dab tsi?
Resins yog ntau lub hauv paus chiv keeb vim peb ncaj qha muab los ntawm cov nroj tsuag oozes whereas plastics yog hluavtaws polymeric xwm. Peb feem ntau muab cov yas los ntawm petrochemicals. Yog li ntawd, lub hauv paus chiv keeb no yog qhov sib txawv ntawm cov resin thiab yas. Ntxiv mus, lwm qhov sib txawv ntawm cov resin thiab yas yog tias cov yas muaj qhov ruaj khov dua, tuaj yeem ua tau thiab tsis muaj impurities, tsis zoo li cov resins uas peb tsis tuaj yeem zam impurities.
Tsis tas li ntawd, plastics qeeb hauv kev degrading thiab, yog li ntawd, ua rau muaj kuab paug ib puag ncig. Tsis tas li ntawd, ntau yam additives hauv plastics muaj cov yam ntxwv lom. Txawm li cas los xij, cov resins, yog ntuj ntshiab, nyob twj ywm ib puag ncig. Yog li ntawd, qhov no yog ib qho tseem ceeb sib txawv ntawm resin thiab yas. Tsis tas li ntawd, lwm qhov sib txawv ntawm cov resin thiab yas yog lawv cov tsos. Plastics yog ib qho nyuaj thiab ntom nyob rau hauv cov xwm, whereas resins yog viscous thiab kua nplaum.
Summary – Resin vs Plastic
Nyob rau hauv cov ntsiab lus, resin thiab plastics yog ib qho tseem ceeb heev cov tebchaw uas muaj hydrocarbon tebchaw. Qhov sib txawv tseem ceeb ntawm cov resin thiab yas yog tias cov resins muaj ntau lub hauv paus chiv keeb vim peb ncaj qha muab los ntawm cov nroj tsuag oozes whereas cov yas yog cov hluavtaws polymeric xwm.
