Ib, Cov nyhuv ntawm UV hluav taws xob sab nraud ntawm cov khoom siv hluav taws xob
Lub hnub tso tawm UV hluav taws xob, thiab nyob ib puag ncig nws rau lub sijhawm ntev tuaj yeem ua rau cov ntaub ntawv yas ntau heev. Lub teeb ultraviolet muaj cov txiaj ntsig tseem ceeb hauv qab no rau cov neeg siv khoom siv hluav taws xob:
Fading thiab fading: Ultraviolet hluav taws xob rhuav tshem cov xim molecules hauv cov yas, uas ua rau cov xim ntawm lub plhaub sab nrauv ploj thiab hloov cov khoom zoo li cas.
Cov khoom muaj hnub nyoog: Ultraviolet lub teeb tuaj yeem rhuav tshem cov saw hlau molecular ntawm cov yas, ua rau lawv nkig, tawv, los yog tawg, uas hloov lub plhaub ntawm cov khoom thiab cov tsos.
Kev puas tsuaj rau saum npoo: Ntev- lub sij hawm raug ultraviolet teeb tuaj yeem ua rau tawg, khawb, thiab lwm yam teeb meem ntawm cov khoom siv hluav taws xob. Qhov no tuaj yeem ua rau cov khoom zoo li tsis zoo thiab ua rau nws tsis txaus siab rau kev siv.
nws yog ib qho tseem ceeb los ua cov casings ntawmcov khoom siv hluav taws xobntau resistant rau UV teeb. Qhov no tsis yog tsuas yog ua kom lawv saib zoo, tab sis nws kuj ua rau cov khoom lag luam ruaj khov thiab txhim khu kev qha.
2, Yuav ua li cas txhaj pwm tuaj yeem pab ua kom cov khoom tiv taus UV rays
Xaiv cov ntaub zoo uas yuav tsis ploj hauv lub hnub.Ua kom zoo dua cov yas uas muaj UV resistant: Ntxiv UV resistant additives rau qee cov yas (xws li polypropylene PP thiab polystyrene PS) tuaj yeem ua rau lawv tiv taus UV rays. Cov additives no tuaj yeem nqus tau UV teeb thiab tiv thaiv cov ntaub ntawv los ntawm nws cov teebmeem.
Polycarbonate (PC), ABS, polyamide (PA), thiab lwm yam yas uas tuaj yeem ua rau ntev - raug UV rays yog cov piv txwv ntawm huab cua- cov polymers tiv taus.
UV absorbers: Cov tshuaj ntxiv no tuaj yeem nqus tau UV rays, nres UV rays los ntawm kev puas tsuaj rau cov qauv molecular ntawm cov yas, thiab ua rau cov khoom tiv thaiv UV rays.
Kev xaiv cov ntaub ntawv raw khoom tsis yog tsuas yog ua kom cov khoom siv hluav taws xob muaj zog tiv thaiv UV rays, tab sis nws kuj tuaj yeem ua kom cov khoom ruaj khov nyob rau lub sijhawm.
3 Txhim kho qhov tsim ntawm kev txhaj tshuaj pwm
Qhov zoo thiab UV tsis kam ntawm lub plhaub tau cuam tshuam ncaj qha los ntawm yuav ua li castxhaj tshuaj pwms yog tsim thiab tsim. Cov khoom no tuaj yeem pab ua kom UV tiv taus zoo dua:
Kev tswj qhov kub ntawm cov pwm: Kev tswj qhov kub ntawm cov pwm thaum lub sij hawm txhaj tshuaj molding txheej txheem tuaj yeem ua kom cov yas hauv pwm txias sib npaug, uas yuav txo qhov nro sab hauv thiab ua kom UV tiv taus. Thaum tshav kub kub ntau dhau ntawm cov pwm tuaj yeem ua rau cov yas ntau dhau, uas tuaj yeem ua rau cov khoom ntawm qhov chaw ntxhib thiab txo qis UV tiv thaiv ntawm rooj plaub.
Txhim kho qhov tsim ntawm cov dej ntws: Kev tsim cov dej ntws zoo tuaj yeem ua kom cov ntaub ntawv sau cov pwm sib npaug thiab tsis txhob muaj qhov tsis muaj zog ntawm kev tsim. Cov hluav taws xob ultraviolet tuaj yeem tau yooj yim los ntawm nyias- cov phab ntsa, yog li cov qauv ntws zoo tuaj yeem pab ua kom lub plhaub tiv taus UV rays.
Smoothness ntawm qhov chaw: Lub smoothness ntawm pwm nto muaj qhov ncaj qha cuam tshuam rau smoothness ntawm lub plhaub nto. Ultraviolet rays tuaj yeem ua mob rau cov ntaub ntawv tsawg dua yog tias lub ntsej muag smoother.thaum tsim cov pwm pwm, nws yog ib qho tseem ceeb kom paub tseeb tias cov pwm saum npoo yog zoo- kho kom tsis txhob muaj kab nrib pleb lossis lwm yam teeb meem.
4, Tshaj tawm - txheej txheem kev txhaj tshuaj
Tom qab- txheej txheem thev naus laus zis kuj tseem ceeb rau kev ua kom UV tiv taus zoo dua, nrog rau cov khoom siv raw thiab kev txhaj tshuaj pwm tsim. Nov yog qee txoj hauv kev los ua kev tshaj tawm - ua:
Txau los tiv thaiv-UV txheej: Txau txheej tiv thaiv- UV txheej sab nraud ntawm cov khoom siv hluav taws xob. Qhov no yuav tiv thaiv UV hluav taws xob zoo, ua rau cov laus ntawm rooj plaub, thiab ua kom cov khoom saib tshiab.
Txheej txheej: Ntxiv aluminium plating, zinc plating, thiab lwm yam rau saum npoo ntawm lub plhaub tsim ib txheej ntxiv ntawm kev tiv thaiv UV hluav taws xob. Cov txheej no qhia txog UV rays thiab ua rau lawv tsis tshua muaj teeb meem rau lub plhaub.ome coatings ntxiv rau UV absorbers, uas tuaj yeem ua rau cov yeeb yaj kiab tiv thaiv ntawm lub plhaub thiab ua kom zoo dua ntawm kev thaiv UV rays.
