Ⅰ. Yuav ua li cas Ultraviolet Lub Teeb "tawm tsam" Yas?
Ua ntej delflving rau hauv cov plastable zoo kawg li, cia thawj zaug tshuaj xyuas "lub zog ua haujlwm" ntawm ultraviolet rays. Lub nthwv dej ntawm UV Rays nyob rau hauv lub hnub ci ranges los ntawm 100 mus rau 400 nanometers, nrog lub zog theem siab txaus los tsoo cov kev sib txuas lus hauv cov molecules. Thaum raug rau UV rays, cov molecular chains tawg thiab reorganize, ua rau cov khoom siv rau discolor, ua rau muaj nkig, thiab thaum kawg poob nws usability. Tsib hom yas peb yog hais txog kev qhia yog zoo li lub hnub qub "hnub yees kev tiv thaiv cov cuab yeej" rau cov khoom siv yas.
Ⅱ. Tsib hom yas uas tiv taus UV Rays?
1. Acrylonitrile - styrenee - acrylate (Asa Acrylate (Asa)
Asa yas yog nyuaj, siab- Lub zog, kev cuam tshuam} Tsis kam, thiab U6 {tsis kam. Nws tseem tiv thaiv huab cua, kub, thiab cov kua qaub tsis muaj zog thiab alkalis. Asa Cheebtsam muaj lub ntsej muag ci thiab tswj lawv cov xim, ci, thiab cov khoom siv neeg kho tshuab txawm tias nyob rau sab nraum zoov chaw. Tom qab 3D luam ntawv, txheej txheej yog yooj yim kom du. Qhov no UV - ion} Cov yas resistant yas tuaj yeem siv los ua kev txhaj tshuaj molding cob los yog raws li lub cnc} {{{}} extruded cov khoom. Lub ntsiab lus tseem ceeb ntawm ASA yog tias nws nqus noo noo sijhawm sijhawm.
Cov ntawv thov rau UV {- tsis kam xws li cov plhaub hluav taws xob, cov rooj tog hluav taws xob, ntaus pob ncaws pob, thiab khoom siv ua vaj ua si. Qhov no UV {-} tiv taus yas kuj tseem siv nyob rau hauv cov ntawv thov tawm ntawm sab nrauv sab nrauv daim iav zoo nkauj. Yog tias koj xav txog kev siv acrylonitrile {4 4}} butadiene {}}} Tab sis tsis muaj ntxiv UV Stabilizers, Abs yuav tsis tiv taus UV degradation.
2. Siab {- ntom polyethylene (HDPE)
HDPE yas ua ke ua ke UV ruaj khov nrog muaj zog thiab dav tsis kam rau nag, cua, daus, thiab huab cua sov. Tsis zoo li asa, no UV {- Cov roj av noo noo tsis nqus cov khoom los ntawm kev nthuav dav, ua tsov rog, lossis tsis muaj zog. Ntawm ntau qhov zoo ntawm HDPE yog nws qhov yooj, lub teeb ci ntsa iab, thiab yooj yim ntawm kev rov ua dua tshiab. Ntxiv rau nws cov tshuaj lom neeg zoo heev, HDPE muaj cov kev cuam tshuam zoo dua, muaj peev xwm nrog nrog cov tshuab uas muaj kev nyuaj siab tsis muaj kev tawg lossis tawg.
Cov ntawv thov rau UV {- Tsis taus siab- Cov Khoom Siv Hluav Taws Xob HDPE kuj tseem siv cov khoom siv hauv tsev rau sab nraum zoov cov qauv, qee zaum tau hu ua yas ntoo, uas muaj cov ntoo ntoo tab sis tsis muaj hnub nyoog. Txawm li cas los xij, tsis yog txhua tus HDPE yog tsim rau cov ntawv thov qauv, yog li cov neeg tsim qauv yuav tsum txiav txim siab khoov cov khoom muaj zog thiab lub zog compressive ntxiv rau UV tsis kam.
3. Polycarbonate (PC)
PC yas muaj kev cuam tshuam ntau dua li HDPE thiab tuaj yeem tiv thaiv qhov kub thiab txias hloov. Qhov no UV {{- Cov khoom siv tiv taus, yooj yim rau cov txheej txheem, insulically insulating, thiab hluav taws kub {{resistant. Txawm hais tias Polycarbonate yog 250 lub sij hawm muaj zog dua iav, PC yog nquag mus khawb thiab kim dua lwm yam U6 5}} Cov ntaub ntawv resistant. Yog li ntawd, thaum xaiv cov ntaub ntawv, cov neeg tsim qauv ib feem yuav tsum sib npaug ntawm UV ruaj khov ntawm Polycarbonate nrog lwm yam.
Cov ntawv thov rau Polycarbonate suav nrog Sab Nraud Signage thiab Cov teeb pom kev zoo. Tshwj xeeb Led diffusion -}}} BEADOLATE yog tsim los diffuse teeb los ntawm LED teeb. Cov txheej txheem txheej txheem ntawm Polycarbonate yas suav nrog Sunshades, Carportions, thiab lwm yam qauv sab nraum zoov. Vim nws cov khoom hluav taws xob zoo nkauj thiab muaj peev xwm ua tau raws cov nplaim hluav taws xob, cov khoom siv hluav taws xob, xws li hloov hluav taws xob hauv cov chaw hloov chaw.
4. Polyamideimide (Pai)
UV {- tiv taus pai tiv taus UV ruaj khov nrog cov cav zoo heev thiab hnav tsis kam. Qhov siab siab no - Kev ua tau zoo yas muaj lub zog loj thiab lub zog compressive, ua rau haum rau cov neeg kho tshuab thauj khoom. Txawm hais tias Pai nqus dej noo thiab muaj cov khoom siv nyuaj ua haujlwm, nws muaj qhov tsis muaj zog ua kom muaj zog thiab muaj kev haum rau qhov chaw ruaj khov. Pai tuaj yeem siv tau rau 3D luam tawm thiab muaj cov txheej txheem zoo, tab sis nws yog kim thiab ua cov kev sib tw rau kev txhaj tshuaj molding.
UV {- ion resistant Pai cov ntawv thov suav nrog Aerospace thiab cov khoom siv hluav taws xob, thiab kev lag luam ntsuab lub zog. Nyob rau hauv Aerospace sector, pai yog siv rau tis, tis, kav hlau txais xov, thiab radar domes. Hluav Taws Xob Hluav Taws Xob thiab cov tshuab hluav taws xob suav nrog cov cab kuj thiab cov txuas. Nyob rau hauv lub zog ntsuab kev lag luam, pai yog siv rau loj {4}?
5. Cov tshuaj fluoridene (PVDF)
PVDF yog lub siab -}} Kev phau tshuaj yas nrog cov tshuaj lom muag zoo, nplaim hluavtaws, thiab cov huab cua. PVDF plastics yog feem ntau muaj nyob rau hauv ob hom: Homopolers thiab Copolymers. Homopolymer PVDF muab cov cua sov siab dua thiab cov cua sov siab dua li Copolymer pvdf, uas nyob rau hauv lem muab kev cuam tshuam zoo dua lub zog thiab tiv taus kev ntxhov siab tawg. Ob cov ntaub ntawv no muaj cov hluav taws xob zoo heev thiab kev nkees ua tsis tau zoo hauv qab ntim khoom.
Huab cua {{0- tiv taus pvdf yog siv rau hauv cov ntawv thov, suav nrog cov hlau vov tsev, nrog phab ntsa hlau, thiab phab hlau pov tseg. PVDF kuj tseem ua haujlwm hauv cov duab dej tsis huv, cov yeeb yaj kiab tiv thaiv, thiab sab nraum zoov hluav taws xob rau hluav taws xob them lub tshuab. Kev lag luam siv PVDF los ntawm 3D machining, lossis txhaj tshuaj molding xws li cov khoom siv kis las, cov khoom siv tsiaj, thiab cov khoom siv semiconductor.
