ABS ntawv yog siv dav siv engineering thermoplastic, paub zoo rau nws qhov sib npaug rigidity, toughness, thiab nto tiav. Hauv ntau daim ntawv thov kev tsim thiab kho kom zoo nkauj, nws ncaj qha sib tw nrog PP (polypropylene) thiab PS (polystyrene). Kev nkag siab tias ABS ua li cas rau lub neej kev pabcuam, kev tiv thaiv ib puag ncig, thiab kev saib xyuas txhua hnub pab cov neeg siv xaiv cov khoom siv zoo dua thiab txuas ntxiv lub neej ua haujlwm ntawm lawv cov khoom.
Piv nrog PP thiab PS, ABS muaj qhov ua tau zoo tshaj plaws. PS yog nruj tab sis nkig, muaj kev cuam tshuam tsis zoo; Nws yog nquag tawg nyob rau hauv me ntsis cuam tshuam, yog li nws cov kev pab cuam lub neej yog luv luv nyob rau hauv high-stress los yog sab nraum zoov ib puag ncig. PP muaj cov tshuaj tiv thaiv zoo heev thiab yoog raws, tab sis tsis tshua muaj rigidity thiab tsis zoo seem stability; nws deforms yooj yim nyob rau hauv tshav kub los yog load, txwv nws siv nyob rau hauv precision structural qhov chaw. ABS muab cov kev tiv thaiv kev tiv thaiv, kev nruj, thiab qhov ruaj khov, ua rau nws ruaj khov dua PS hauv kev siv mus ntev thiab ruaj khov dua li PP hauv qab load thiab kub.
Raws li cov xwm txheej hauv tsev, xws li kho kom zoo nkauj sab hauv, kos npe tshaj tawm, hluav taws xob vaj tse, thiab tsheb sab hauv vaj huam sib luag, ABS daim ntawv tuaj yeem tswj xyuas kev ua haujlwm ruaj khov rau10 mus rau 20 xyoo. PS feem ntau kav ntev3a8 xyaua ntej yuav brittle los yog yellowing. PP tuaj yeem siv tau ntev heev, tab sis nws softens thiab deforms lub sij hawm, yog li nws cov kev pab cuam lub neej zoo nyob rau hauv cov qauv siv yog5 mus rau 10 xyoo. Nyob rau hauv ib puag ncig sab nraum zoov, tsis hloov kho ABS degrades sai dua vim UV hluav taws xob, nrog rau lub neej kev pab cuam ntawm2a5 xyoo, thaum UV-stabilized ABS tuaj yeem ncav cuag5 mus rau 10 xyoo. PP muaj cov huab cua tsis zoo thiab tuaj yeem nyob sab nraum zoov ntev dua, tab sis nws qhov kev nruj tsis tshua muaj kev txwv. PS tsis haum rau kev siv sab nraum zoov mus ntev.
Txhawm rau ua kom lub neej ua haujlwm siab tshaj plaws ntawm cov ntawv ABS, kev saib xyuas txhua hnub yog qhov tseem ceeb. Ua ntej, tsis txhob raug mus ntev rau lub hnub ci zog thiab kub siab. UV hluav taws xob ua rau yellowing, chalking, thiab poob ntawm toughness, yog li kev siv sab nraum zoov yuav tsum siv cov qib UV-resistant los yog ntxiv cov txheej tiv thaiv. Thib ob, khaws ABS kom deb ntawm cov kuab tshuaj muaj zog xws li ketones, esters, thiab roj av, uas tuaj yeem ua rau o, tawg, lossis puas tsuaj. Cov tshuaj ntxuav me me thiab cov ntaub mos muag tau pom zoo rau kev ntxuav. Thib peb, tsis txhob muaj kev ntxhov siab ntau dhau ntawm kev siv tshuab thiab cuam tshuam. Txawm hais tias ABS muaj lub zog zoo, lub sijhawm ntev hnyav lossis rov ua dua tuaj yeem ua rau microcracks thiab qhov kawg tsis ua haujlwm. Plaub, tswj cov ntawv thov kub. ABS ua tau zoo tshaj plaws ntawm -20℃thiab 60 degree; Lub sij hawm ntev kub ceev ceev thermal aging thiab deformation.
Hauv cov ntsiab lus, ABS daim ntawv muaj qhov sib npaug ntawm kev pabcuam lub neej, kev ua haujlwm zoo, thiab kev ua haujlwm piv nrog PP thiab PS. Nws outlasts PS nyob rau hauv durability thiab outperforms PP nyob rau hauv seem stability thiab rigidity. Nrog kev xaiv cov khoom tsim nyog thiab kev saib xyuas tsim nyog, ABS tuaj yeem muab kev pabcuam ruaj khov, kev pabcuam ntev hauv tsev thiab kev tiv thaiv sab nraum zoov. Rau cov chaw tsim khoom, cov neeg tsim qauv, thiab cov neeg siv khoom, xaiv ABS txhais tau tias xaiv tus nqi tsim nyog, kev daws teeb meem ntev rau cov qauv thiab cov khoom zoo nkauj.
