Tshawb xyuas cov duab zoo zoo
Plexiglass khoom siv lo lo ntxhuav khoom ua haujlwm tsuas ua raws li plaub lub luag haujlwm ntawm cov yas scraping ua si zoo thiaj li luam tau tawm ntawm cov khoom siv tes ua cov twj pleev xim. Thiab lub cev nqaij daim tawv ua rau khauj khaum saum toj no ua rau lub luag haujlwm tseem ceeb. (Piv txwv, lub siab tawv ntawm cov yas scraping yuav ua tau zoo heev ntawm tus lej cim, tiam sis tsis tuaj yeem ua tau raws li cov kev cai ntawm ntau yam khoom sib txawv). Yog li ntawd, nyob rau hauv cov kev xaiv ntawm cov yas scraping, coj tag nrho cov account ntawm tej yam ntawm scraping performance yam tseem ceeb, kom tsis txhob muaj cov teeb meem phom sij rau cov nyhuv luam. Thaum xaiv cov kev ua tau zoo ntawm cov yas scraping, yuav tsum xav txog plaub yam hauv qab no:
1. Hardness: cov yas scraping yog feem ntau yog ua los ntawm polyurethane, nrog ib qho tawv tester ntsuas qhov nyuaj ntawm rubber scraping. Qhov nyuaj, qhov loj me thiab khov khov ntawm scraper txiav txim siab rau qhov kev sib tw, kev yooj yim thiab siab ntawm lub squeegee. Hardness ntau ntawm 55 degrees txog 90 degrees (Shore A). Tus nqi ntawm qhov hnyav yog ntsuas nrog lub Shom A ntsuas. 55A-65A yog ib lub hnab yas qis, 66A-75A nyuaj, ntau dua 75A nyuaj thiab nyuab
Lub siab ua kom lub siab tawv yog qhov zoo tshaj plaws rau peb thawj zaug ntawm lub cwjmem, nias tus number case rau hauv kev tshuaj ntsuam thiab xa cov cwj mem los ntawm lub nplhaib nplua rau lub substrate thiab tuav cov hlau nyob rau hauv kev sib txuas nrog lub phaj plexiglass. Qhov teeb meem ntawm lub siab tawv tsis tuaj yeem tsis tau raws li kev luam tawm ntawm cov khoom sib txawv ntawm cov khoom tsis zoo, nyob rau hauv qhov chaw luam ntawv ntxhib thiab tsis sib txig ntawm cov yas scraping cov kev xav tau zoo kuj yog siab.
2. Siv dav: hais txog cov khoom txeem mus rau hauv txhuas tus txhuas, los ntawm cov txhuas kov ntawm cov yas scraping dav. Qhov dav no yog qhov tseem ceeb thiab txiav txim siab lub caij nyoog ntawm lub ciam hauv kev siab ceev. Curvature yog qhov dav zoo ntawm qhov cubic tus nqi. Xws li ob zaug qhov dav dav ntawm khoov yog siab tshaj 23 degrees.
Tus cwj pwm yuav ua rau ob lub pauv hloov: lub kaum sab xis ntawm lub cwj mem thiab lub vijtsam hloov; lub tshuab luam ntawv siab tuaj yeem txo qis rau cov khoom tsis zoo. Piv txwv li, cov yas scraping piv rau ib pawg ntawm springs, thaum lub caij nplooj ntoos hlav rau hauv ib lub hauv paus qe quab yuam, lub caij nplooj ntoos hlav pib khoov, kis tau ntawm cov quab yuam tau txais me thiab me. Roj hmab scraping luam lub kaum sab xis yog txo, lub print siab tsis txaus, cov nyhuv luam ntawv tsis zoo tagnrho. Lub kaum sab xis zauv me me, lub tshuab luam ntawv yog txo, tus lej ntawm tus lej hauv qab ntawm txheej plev txheej thickening. (Hauv qhov no, tus neeg teb xov tooj luam yuav ua rau kom muaj kev nyuaj siab ntxiv, cov hnab yas khoov yas ntxiv tsis zoo, lub plhaub ntim quav tseem tsis zoo rau qhov kev daws teebmeem. cov nyhuv ntawm qhov dav ntawm plaub kev khiav dej ntawm cov kua nplaum.
Feem ntau qhov dav dav ntawm lub squeegee ntawm 20MM rau 30 hli. Kev xaiv ntawm qhov zoo tshaj plaws dav dav yog raws li tus nyob ntawm qhov khoom plexiglass, kev daws teebmeem duab thiab lwm yam luam tsis zoo xws li lub kaum sab xis ntawm scraping, qhov ceev thiab hom ntawm number case. Nyob hauv lub nqab / du dawm substrate uas sau rau ntawm qhov siab ntawm daim duab, qhov dav dav ntawm me me (tsawg dua 20MM), siab zog, nrog rau tus cwj pwm tsim nyog rau ceev ceev luam ntawv. Nyob rau hauv cov tsis ncaj, lub ntsiab lus khov, qhov dav dav kom zoo (qee zaum tus me nyuam loj 30MM), txo hwjchim, thiab ua kom tsis tshua muaj zog kom hloov tsis tau lub peev xwm, tsis txhob siv ntau txoj hlua, koj tuaj yeem siv nruab nrab ntawm qhov nyuaj ntawm peb sab ntawm mos los yog ob txheej Txhooj. Feem ntau, qhov dav dav yog nce, qhov kev luam tawm tsawg zog thiab lub kaum ntse ntse luam yog nce.
