Scratch thiab hnav tsis kam yog cov cim tseem ceeb uas txiav txim siab qhov zoo li khaws cia thiab kev pabcuam lub neej ntawm cov khoom yas, npog cov khoom siv hauv tsev, cov khoom siv sab nraum zoov, cov khoom siv hluav taws xob, thiab cov khoom siv sab nrauv tsheb. Rau cov tuam txhab tsim khoom thiab cov neeg tsim khoom, xaiv cov ntaub ntawv yas zoo yog qhov tseem ceeb rau kev txhim kho cov khoom ruaj khov thiab kev sib tw ua lag luam. Nyob rau hauv cov ntaub ntawv yas tseem ceeb ntawm lub lag luam thoob ntiaj teb, cov ntawv yas tawv tawv muaj qhov pom tseeb ntawm kev khawb tsis zoo:PC> ASA> ABS> HIPS. Tsis tas li ntawd, ntshiab TPU sawv tawm ntawm tag nrho cov ntaub ntawv, xa qhov zoo tshaj plaws hnav tsis kam rau siab - thov kev tiv thaiv daim ntawv thov.
PC (Polycarbonate) cov ntawv txheeb npe thawj zaug hauv kev khawb tsis kam ntawm cov yas tawv tawv. Featuring high deg hardness, zoo heev toughness, thiab zoo heev tej yam kuj, PC los xij ua kom ruaj khov nyob rau hauv huab cua kub xws li ntawm -40℃mus rau 130 degree. Lawv tsis yooj yim khawb los ntawm cov khoom nyuaj niaj hnub xws li cov yawm sij thiab pob zeb, thiab lawv kuj khav theeb zoo lub teeb xa tawm. Ua tsaug rau cov khoom zoo tshaj no, cov ntawv PC tau siv dav hauv kev tiv thaiv lub ntsej muag, siab -cov khoom siv hauv tsev kawg, cov khoom siv sab nraum zoov, thiab lwm yam xwm txheej uas yuav tsum tau ua kom zoo nkauj thiab cov qauv siv tau ntev. Qhov kev txwv nkaus xwb yog tias PC ntshiab tuaj yeem tsim cov khawb zoo tom qab ntev - kev sib txhuam, nrog me ntsis qis dua - lub sij hawm hnav tsis kam tshaj li cov khoom siv elastic hnav-resistant.
ASA cov ntawv tuaj thib ob tsuas yog rau PC hauv kev khawb tsis kam, nrog rau cov huab cua tshwj xeeb ua rau lawv cov txiaj ntsig tseem ceeb. Qhov tawv tawv ntawm ASA tuaj yeem ncav cuag qib 2H, tswj cov khoom siv kho kom ruaj khov ntawm -30℃yam tsis muaj tawg, fading, lossis pulverizing. Sib txawv ntawm cov yas zoo tib yam uas muaj hnub nyoog tawm sab nraum zoov, ASA hloov mus rau lub sijhawm ntev ntawm cov hluav taws xob ultraviolet thiab kub hloov, ua rau nws nyiam cov khoom siv rau cov tsheb sab nrauv, cov khoom siv hluav taws xob sab nraud, cov khoom siv hluav taws xob sab nraum zoov, thiab lwm yam khoom siv sab nraum zoov.
ABS yog ntau yam thiab tus nqi-cov yas siv tau zoo nrog kev ua haujlwm sib luag, ua haujlwm yooj yim, thiab kev ua haujlwm xim zoo nkauj, tuav txoj haujlwm tseem ceeb hauv khw muag khoom. Txawm li cas los xij, nws qhov kev tiv thaiv khawb yog pom tseeb tsis muaj zog dua li PC thiab ASA. ABS nto yog qhov pom kev khawb hauv kev siv txhua hnub, yog li nws feem ntau siv rau cov khoom siv sab hauv tsev xws li lub nra, cov khoom siv hauv tsev zoo tib yam, thiab cov khoom ua si uas tsis tshua muaj hnav tsis kam. Cov nplooj ntawv HIPS muaj qhov khawb tsis zoo tshaj plaws ntawm plaub tawv tawv. Cov khoom muag muag ua rau muaj kev hnav tsis zoo, txwv nws daim ntawv thov kom tsawg -xav tau qhov xwm txheej xws li ntim khoom ib ntus thiab kho kom zoo nkauj sab hauv.
Raws li cov thermoplastic polyurethane elastomer, ntshiab TPU ua tiav cov ntawv yas tawv tawv hauv qhov hnav thiab khawb tsis kam. Nws muaj qhov tshwj xeeb ntawm tus kheej - kho cov cuab yeej, qhov twg cov khawb me tuaj yeem ploj zuj zus nyob rau hauv lub teeb thiab kub. Meanwhile, TPU nta yooj, tiv thaiv -slip kev ua tau zoo, siab tensile lub zog, thiab aging kuj. Nws yog feem ntau siv los ua txheej txheej txheej thiab tiv thaiv txheej rau ntau yam khoom yas, ua kom zoo dua qub hnav thiab khawb tsis kam ntawm cov khoom, uas yog qhov kev xaiv zoo tshaj plaws rau siab -kawg hnav- tiv thaiv kev daws teeb meem.
Txhawm rau ua kom tiav, cov neeg tsim qauv tuaj yeem xaiv cov ntawv yas nyuaj raws li qib ntawm PC, ASA, ABS, thiab HIPS raws li cov xwm txheej siv tiag tiag. Rau cov khoom ua raws li huab cua hnav tsis kam, ntshiab TPU yog qhov tseem ceeb tshaj plaws. Cov khoom tsim nyog sib piv tuaj yeem sib npaug cov khoom zoo li zoo thiab ntev - lub neej kev pab cuam.
