1, ABS yas
Yam ntxwv
(1) Zoo tag nrho kev ua tau zoo, muaj zog cuam tshuam, zoo tshuaj lom neeg ruaj khov, hluav taws xob zoo;
(2) Kev sib xyaw zoo nrog pmma, tuaj yeem ua rau ob xim yas, qhov chaw tuaj yeem yog chrome-plated, tshuaj tsuag xim;
(3) Muaj kev cuam tshuam tsis zoo, kub kub tsis kam, nplaim hluav taws, txhim kho, pob tshab thiab lwm qib;
(4) Lub fluidity yog me ntsis phem dua HIPS, zoo dua PMMA, PC thiab lwm yam yooj.
ABS resin resistant rau dej, inorganic ntsev, alkalis thiab acids, insoluble nyob rau hauv feem ntau cawv thiab hydrocarbon solvents, tab sis soluble nyob rau hauv aldehydes, ketones, esters thiab ib co chlorinated hydrocarbons.
Qhov tsis zoo ntawm ABS engineering yas: tsis tshua muaj cua sov distortion kub, combustible, huab cua tsis zoo.
2, ABS + PC
Yam ntxwv
Tsis tuaj yeem tshwm sim spontaneous combustion, sab nraud hluav taws kub combustion, nto ntawm polycarbonate combustion zoo li tib me me nag los nag. Thaum cov nplaim hluav taws sab nraud nres, qhov hluav taws xob kuj nres.
3, PC Polycarbonate
Cov ntawv luv luv PC engineering plastics, cov khoom siv PC yog qhov peb hu ua ib qho ntawm cov yas engineering, raws li cov khoom siv dav siv los ntawm cov teb chaws thoob ntiaj teb.
1) Cov yam ntxwv
Polycarbonate tsis muaj xim thiab pob tshab, kub-tiv taus, cuam tshuam-tiv taus, nplaim-retardant, thiab muaj cov khoom siv zoo ntawm kev ua haujlwm kub. Piv nrog polymethylmethacrylate, uas yog ze rau hauv kev ua tau zoo, polycarbonate muaj kev cuam tshuam zoo, siab refractive index, thiab kev ua tau zoo.
2) Qhov tsis zoo
Kev puas tsuaj ntawm polycarbonate tsis zoo, thiab qee cov khoom siv polycarbonate siv rau kev puas tsuaj-tiv taus yuav tsum tau kho tshwj xeeb ntawm qhov chaw.
Cov ntawv thov niaj hnub niaj hnub muaj xws li cov discs, lub qhov muag qhov ncauj qhov ntswg, lub raj mis dej, iav mos txwv, tsom iav, iav tsom iav rau cov tsev txhab nyiaj, teeb taub hau, thiab lwm yam, tsiaj tawb, thiab tsiaj tawb.
Polycarbonate kuj tseem siv rau hauv kev tsim cov kaus mom kaus mom hlau rau lub hli tsaws astronauts.
Apple's ipod music player thiab ibook laptop plhaub kuj yog ua los ntawm polycarbonate.
4. PMMA polymethyl methacrylate
Disadvantages: nto hardness tsis siab.
PMMA deg hardness tsis siab, yooj yim rau kev sib txhuam plaub hau, tsis tshua muaj kev cuam tshuam tsis kam, ua cov dej tsis zoo.
Ultra-pob tshab PMMA cov khoom siv tsuas yog siv rau lub xov tooj ntawm tes tiv thaiv kev tshuaj ntsuam, cov khoom tau muab faib ua ob hom txheej tawv tawv, tsis muaj txheej tawv tawv.
Yam ntxwv
Lub teeb kis tau zoo heev, tsis muaj impurities, electrostatic tiv thaiv zaj duab xis, deg hardening tuab hardness mus txog 5-6H lossis ntau dua.
Tam sim no tshwj xeeb tshaj yog pom zoo rau PMMA khoom hardening, domestic hu ua 'raw board'.
5.PP Polypropylene
1) Nta
Non-toxic, odorless, degree ntawm me me, lub zog, nruj, hardness thiab kub kuj yog zoo dua li tsawg-pressure polyethylene, yuav siv tau ntawm txog 100 degrees. Nws muaj cov khoom siv hluav taws xob zoo, cov hluav taws xob ntau zaus tsis cuam tshuam los ntawm cov av noo.
2) Qhov tsis zoo
Siab brittleness ntawm qis kub, tsis hnav-resistant, yooj yim rau kev laus.
3) Siv
Haum rau kev tsim cov khoom siv dav dav, qhov chaw corrosion-resistant thiab insulating qhov chaw.
Cov kua qaub, alkalis thiab cov kuab tshuaj organic tsis tshua muaj txiaj ntsig rau nws, thiab nws tuaj yeem siv rau cov tais diav.
6. PE Polyethylene
Polyethylene tsis muaj ntxhiab tsw, tsis muaj tshuaj lom, zoo li siv quav ciab, muaj qhov kub thiab txias tsis kam (qhov qis tshaj siv kub txog -70 ~ -100 degree), zoo tshuaj stability, resistant rau feem ntau ntawm cov acids thiab alkalis (tsis resistant rau oxidative zog ntawm acids), insoluble nyob rau hauv ntau cov kuab tshuaj nyob rau hauv chav tsev kub, me me nqus dej, zoo heev hluav taws xob rwb thaiv tsev zog;
