Thaum xaiv cov engineering thermoplastic rau cov ntawv thov uas xav tau, feem ntau xaiv feem ntau nqaim rau ob lub zog sib cav: ABS thiab ASA. Thaum Abs yog ib qho zoo {{-} yog nquag to douted li nws zoo dua, {2} {tsis kam hloov. Tab sis yog tias tag nrho zaj dab neeg?
Qhov no in - cov lus qhia tob mus tshaj qhov sib piv yooj yim. Peb yuav tshem tawm cov tshuaj pleev cov tshuaj, cov khoom siv neeg kho tshuab, thiab tiag- ntiaj teb kev ua haujlwm ntawm ASA thiab ABSATE los pab koj ua qhov kev txiav txim siab paub.
Cov tub ntxhais sib txawv: nws yog txhua yam hauv cov roj hmab
Qhov tseem ceeb sib txawv nyob hauv lawv cov qauv tshuaj, tshwj xeeb hom roj hmab siv los muab cuam tshuam.
ABS (Acrylonitrile Butadiene STyrene):"B" sawv rauRab nyom, cov roj hmab uas ua tau zoo heev tab sis muaj qhov tsis muaj zog: nws muaj cov carbon - Cov pa roj carbon monoxide ntau dua thaum ultraviolet (UV) ntawm lub hnub.
Asa (Acrylonitrile Styrende Acrylate):Tus "A" hloov pauv butadiene nrog ibMuaj acrylate-} Raws roj hmab. Cov roj hmab acrylate no tau ruaj khov rau UV hluav taws xob vim tias nws tsis muaj cov nyiaj tsis raug ob npaug.
Qhov no ib qho chaw hloov pauv yog vim li cas rau kev ua tau zoo tshaj plaws sab nraum zoov.
Hauv - qhov tob ntawm cov khoom sib piv: ASA Vs. ABS
Cia peb tsoo lawv cov yam ntxwv nrog cov ntsiab lus ntxiv.
| Ntiag tug | Abs | ASA | Tseem Ceeb Takaway |
|---|---|---|---|
| UV & huab cua Kuj | Pluag.Dhau los ua brittle, fades, thiab tsim cov nrib pleb (chalking) hauv6-12 hlisntawm sab nraum zoov kis. | Zoo heev.Khaws cov tawv tawv thiab xim rau5-10 xyoo lossis ntau duaCov. Feem ntau suav cov roj dub rau qhov siab tshaj UV ruaj khov. | Asa yog tus yeej tsis muaj txiaj ntsig rau txhua daim ntawv thov sab nraum zoov. |
| Cuam tshuam lub zog (tawv) | Zoo heev nyob rau hauv chav tsev kub. Txawm li cas los xij, kev cuam tshuam lub zog plummets ntawm tsawg kub (qis dua 0℃/℃F). | Zoo heev thiab, qhov tseeb,zoo dua nyob thoob plaws ntawm qhov kub thiab txiasCov. Nws khaws cov tawv tawv zoo dua hauv cov chaw txias. | Asa muaj ntau cov kev ntseeg ruaj khov dua, tshwj xeeb tshaj yog nyob rau hauv cov huab tais nce siab. |
| Thaum Tshav Kub Kub Ua Haujlwm (HDT) | Zoo. Thaum tshav kub kub deflection kub (hdt @ 1.8 MPA) feem ntau{{085 - 100℃(185 - 212℃f). | Zoo dua zoo dua. HDT feem ntau{{090 - 105℃(194 - 221℃f). | Asa muaj me ntsis tab sis muaj txiaj ntsig zoo nyob rau hauv high - qhov chaw ib puag ncig. |
| Tshuaj Kuj | Zoo tsis kam rau ntau cov acids thiab alkalis.Tawm tsam los ntawm polar solvents xws li acetone(uas pub rau vapor smoothing). | Tshuaj zoo heev tshuaj tiv thaiv.Zoo tshaj qhov kev ntxhov siab ib puag ncigXws li oxidation thiab hydrolysis (kev nqus dej). Nws tseem tiv taus ntau yam kua roj ntau. | Asa zoo dua withstals ntev - chinestment ib puag ncig cov tshuaj.ABS yog yooj yim tshaj tawm - txheej txheem vim nws solubility. |
| Deg tas & Post -} ua | Zoo heev.Sands zoo thiab tuaj yeem welded nrog acetone los tsim lub siab - ploss, seamless tiav. Yooj yim pleev xim nrog primers. | Zoo, tab sis txawv.Tsis du nrog acetone. Yuav tsum muaj cov kev qhia tshwj xeeb (piv txwv li, cov tshuab hluav taws xob, ketones) rau kev sib raug zoo. Muaj zoo heevColourFastness; Pigments nyob sab nraum zoov. | ABS yeej rau kev yooj yim ntawm kev tiv thaiv thiab ua tiav hauv tsev.Asa yeej rau ntev - sij hawm estchaetic ruaj khov sab nraum zoov. |
| Nqi & Muaj | Tus nqi qis thiab muaj heev.Ib qho ntawm cov kev lag luam kev lag luam plastics. | Feem ntau 20-40% kim dua abs.Tsawg ubiquitous, tab sis tau yooj yim muaj los ntawm cov khoom siv yas loj. | ABS yog cov nyiaj txiag - Tus phooj ywg xaiv rau nqi rau tus nqi-} cov phiaj xwm rhiab. |
Lub Sijhawm Txiav Txim Siab: Ntawv Thov {{{}}} Raws li xaiv
Xaiv ABS yog tias koj txoj haujlwm ua tau raws li cov qauv:

Xaus: Qhov Kev Txiav Txim
Kev xaiv nruab nrab ntawm ASA thiab ABS tsis yog hais txog cov khoom twg yog "zoo dua" hauv kev nkag siab tiag, tab sis uas yogZoo dua rau ib puag ncig uas nws yuav ua haujlwm.
Xav txogAbs raws li cov khoom, nqi -} Tus Kws Tshaj Lij Zoo Tshaj Plaws Hauv Tsev.Nws yog qhov mus -}}}} Xaiv rau ntau cov kev siv ntawm kev siv UV kis tau tsis yog ib yam.
Xav txogAsa raws li cov rugged, huab cua -}} proof eam pov thawj sab nraum zoov tus yeej.Nws tau tsim tshwj xeeb los daws cov tsis muaj zog loj tshaj plaws.
Rau txhua qhov project uas yuav pom lub teeb ntawm hnub, kev nqis peev hauv Asa yog kev nqis peev hauv ntev {}}}}} kev nyab xeeb, thiab tsos. Thaum ua tau zoo nyob rau hauv lub hnub tsis yog- sib tham, Asa yog qhov tseeb thiab xaiv tau.
