iav hlaws nrog refractive indexes ntawm 1.9 thiab 2.2
Sandblasting iav hlaws
Junda iav hlaws yog ib hom abrasive blasting rau nto tiav, tshwj xeeb los npaj cov hlau los ntawm smoothing lawv. Bead blasting muab kev ntxuav zoo tshaj plaws kom tshem tawm cov xim, xeb thiab lwm yam txheej txheem.
Cov iav hlaws blasting txheej txheem yog ib puag ncig-phooj ywg thiab tsis muaj tshuaj lom neeg thiab tuaj yeem siv los xyuas cov vuam thiab vuam qhov tsis zoo. Qhov zoo ntawm kev siv iav hlaws blasting muaj xws li:
●Ntau ntau qib muaj rau ntau txoj haujlwm thiab cov profiles.
●Tsis cuam tshuam nrog coatings vim nws tsis reactive.
●Nws tawm tsis muaj residue los yog embedded contaminants, thiab kuj tsis ua rau ib tug loj qhov chaw hloov.
●Txhim kho corrosion kuj thiab muaj peev xwm ua kom du tawm ntawm qhov chaw flaws.
●Tsis pom muaj crystalline silica.
Nws ua haujlwm li cas?
Junda iav hlaws blasting tseem ceeb siv cov iav hlaws zoo ntawm ntau qhov ntau thiab tsawg ntawm qhov sib txawv ntawm qhov siab. Cov iav spheres me me ua rau lub ntsej muag du dua thaum cov spheres loj dua ua kom zoo nkauj dua.
Cov hlaws iav tsis tshem tawm ib qho ntawm lub hauv paus hlau lossis imbed rau saum npoo. Nws yuav ua kom zoo dua, zoo dua qub thaum tseem ntxiv qhov ci los yog ci ntsa iab rau ib feem.
Nws muaj ntau yam kev siv, suav nrog:
●Kev Ua tiav: tuaj yeem siv rau ntau yam khoom siv, suav nrog hlau, iav, yas thiab roj hmab.
●Kev Tu: Tsis ua rau lub ntsej muag hloov pauv, iav hlaws blasting tshem tawm / ntxuav cov khoom txawv teb chaws.
●Deburring: Yuav kom sib sau thiab ua haujlwm, cov ces kaum thiab cov npoo yuav tsum tau deburred. Iav hlaws blasting tuaj yeem tshem tawm burrs thiab feathered npoo thaum ua kom tsis muaj hlau los ntawm qhov chaw raug tshem tawm.
●Peening: Peening ncua lub neej ntawm cov hlau qhov chaw los ntawm kev sib ntaus sib tua kev ntxhov siab tawg thiab corrosion.
Cov iav hlaws dai rau kev kos duab ntawm txoj kev
Junda Road marking iav hlaws yog tsim los ntawm iav xuab zeb, iav khib nyiab raws li cov khoom siv raw, tom qab kub kub yaj thiab tsim cov iav me me, nyob rau hauv lub tshuab tsom iav raws li cov xim tsis muaj pob tshab, txoj kab uas hla ntawm 75 microns mus rau 1400 microns, tam sim no nyob rau hauv cov khoom tseem ceeb ntawm txoj kev reflective iav hlaws txheej txheem yog nplaim ntab txoj kev.
Junda Road marking iav hlaws yog tsuas yog siv nyob rau hauv ib txwm kub hom, kub yaj hom txoj kev npav txheej, ib yam li premixed khoom, muaj peev xwm xyuas kom meej lub cim nyob rau hauv lub neej lub sij hawm ntawm kev xav, ib tug nyob rau hauv lub marking kev tsim kho nto kis, muaj peev xwm ua si ib tug reflective nyhuv.
Cov hlaws iav yog siv los ua ib hom kev ua haujlwm siab, cov khoom siv organic rau sab nraum cov iav hlaws, ua cov iav hlaws tsis muaj zog tshwm sim ntawm qhov chaw adsorption ntawm cov plua plav hauv huab cua, vim yog cov iav hlaws uas muaj cov neeg sib txuas tshwj xeeb, txhim kho cov hlaws dai thiab cohesive quab yuam ntawm txheej tuaj yeem tiv thaiv qee cov iav me me hlaws rau txheej, vim tias nws cov flotability muaj nuj nqi, thaum siv ntab saum npoo txheej, Nws muaj thaj tsam loj, tuaj yeem ua rau kom muaj nuj nqis. Kev siv tus nqi ntau dua 30%, tam sim no cov iav tsom iav tau dhau los ua cov khoom siv tsis muaj kev cuam tshuam hauv kev nyab xeeb khoom.
Peb tuaj yeem muab cov iav hlaws nrog qhov sib txawv ntawm qhov ntsuas ntawm 1.53, 1.72, 1.93 thiab lwm yam, Peb tuaj yeem muab cov iav hlaws ntawm ntau lub teb chaws tus qauv, lossis raws li qhov loj me muab los ntawm cov neeg siv khoom.

Sib tsoo iav hlaws
Junda Sib Tsoo iav hlaws yog ib hom iav hlaws nrog qhov loj me, du nto, siab hardness thiab zoo tshuaj stability. Sib tsoo hlaws yog feem ntau iav hlaws nrog ib qhov loj me dua 1 hli. Lawv tsis muaj xim thiab pob tshab hauv qhov tsos thiab yog ib qho huv si. Nws yog dav siv nyob rau hauv cov xim, xim, number case, tshuaj lom neeg kev lag luam thiab lwm yam dispersing tus neeg sawv cev, sib tsoo nruab nrab thiab sau cov ntaub ntawv.
