Cov ntaub ntawv siv rau qhov kev npaj ntawm kev tshuaj ntsuam yog paj rwb, xaws, nylon, polyester, stainless hlau hlau, tooj liab hlau thiab lwm yam hlau. Thaum muab cov ntawv luam tawm cov ntawv luam tawm, koj yuav tsum muaj kev nkag siab txog cov ntaub npog ntsej muag hlau thiaj li tsim tau lub hauv paus rau kev xaiv kom raug thiab kev tsim cov khoom zoo siab ntawm cov ntawv luam.
Ua ntej, tus yam ntxwv ntawm cov hlau mesh khoom
Cov ntawv xov tooj paj rwb: Vim lub pluag uniformity ntawm warp thiab weft, mesh loj yog inconsistent thiab cov duab sib txawv; cov paj rwb muaj plua plav smoothness, low tensile strength thiab low pressure tsis kam; Paj ntaub xov tooj ntawm lub tshuab luam ntawv Qhov zoo ntawm cov phaj luam ntawv tsis zoo, kev daws teeb meem, thiab cov nyhuv luam tsis zoo, yog li nws tsis tshua siv.
Cov xaim hlau xiav: nws lub xov tooj cua thiab qhov tsis nyhav, lub zog thiab qhov kawg ntawm qhov siab yog siab dua paj rwb gauze. Qhov tsis zoo yog tias qhov elongation loj heev, nws yog ib qho yooj yim rau lub hnub nyoog thiab tsis zoo, lub teeb ua haujlwm tsis zoo, thiab nws yog yooj yim ua brittle tom qab ntev mus rau lub teeb. .
Nylon mesh: Nws yog woven los ntawm ib tug hluavtaws fiber - polyamine fiber. Muaj ntau ntau hom thiab monofilaments nyob rau hauv lub weave. Lub thickness ntawm warp thiab weft yuav ua tiav raws li kev cai sib txawv. Qhov ceev ntawm thaj tsam ntawm lub mesh yog qhov sib txawv, qhov kev ua haujlwm tsis zoo yog qhov zoo, qhov elongation yog qis tshaj li ntawm qhov lo lo ntxhuav, thiab cov phaj luam tawm ntawm nylon mesh yog tsawg dua qub thaum siv. Qhov tsis zoo yog tias cov kua qaub kuj tuaj me ntsis tuaj.
Polyacetal Mesh: Tsis tas li ntawd hu ua polyester mesh, nws tseem yog woven los ntawm ib qho hluavtaws fiber. Lub thickness ntawm warp thiab weft threads kuj yuav ua raws li txoj cai. Mesh cheeb tsam thiab qhov ceev yog qhov tseem ceeb heev. Cov tshuaj lom neeg kuj muaj zog dua li cov nylon mesh, thiab nws cov elongation qis tshaj qhov nylon mesh. Qhov tsis zoo yog qhov hluav taws xob zoo li qub thaum luam ntawv, thiab cov dej cov dej tsis zoo rau nylon mesh.
Hlau mesh: hais txog ib lub xov hlau woven nrog stainless hlau xaim los yog hlau xaim, thiab ib qho xaim mesh ua ntawm electroplated hlau nickel. Nws yog lub zog ntawm lub zog, kev ua haujlwm zoo, kev ua haujlwm zoo, kev kub siab, thiab hluav taws xob ua kom zoo. Nws yog ib qho yooj yim rau cua sov thaum lub sij hawm luam tawm, thiab yog tsim rau kev tshuaj ntsuam luam ntawv inks lossis pastes uas yuav tsum tau cua sov. Lub disadvantage ntawm cov hlau mesh yog tias qhov elasticity me me, tus mesh muaj ib lub caws thiab elasticity tsis tau rov qab, thiab nws tsuas yuav muab pov tseg.
Hauv cov ntawv luam tawm tshiab, nylon mesh feem ntau yog siv los ua cov ntawv xov xwm, tab sis nyob rau hauv qhov tseeb ntawm cov duab kos duab, polyester mesh thiab hlau mesh feem ntau siv los ua cov phaj luam ntawv substrate.
Qeb ob, nws yog cov khoom siv hlau xaim hlau
Muaj ntau hom vijtsam nyob hauv kev ua lag luam, thiab muaj ntau qhov sib txawv hauv daim ntawv ntawm weaving, tab sis raws li cov ntaub ntawv tseem ceeb ntawm weaving, muaj cov nram qab no.
Hloov kho: Nws yog daim ntawv uas nrov tshaj plaws ntawm kev pauv. Qhov no zoo li daim ntawv uas nws tau ua tau zoo dua lub zog thiab kev sib luag. Qhov tsis zoo yog tias tom qab qhov kev ntsuam xyuas raug rau lub siab ntawm tus cwj pwm, qhov nyiag yog yooj yim hloov, ua rau cov duab kom ncab. Vim yog lub qauv tsis ruaj tsis khov, lub ntsej muag ntawm daim ntawv zoo li no nws tsis yooj yim luam tawm, thiab cov luam tawm ntau dhau los yuav ua rau kom tsis muaj teeb meem loj hauv cov khoom thiab lub hauv ntej.
Braided hlav: Qhov hom ntawm nws daim ntawv ntawm qhov screen tau zoo heev tuaj ntawm kev ua kom zoo nkauj, yuav ua kom muaj qhov tseeb ntawm daim duab, yuav tsum tsis txhob muaj qhov txav ntawm kev nyiag los ntawm lub siab ntawm lub squeegee, thiab lub thickness ntawm woven ntaub ntawm braid yog obviously nce. Lub plhaub ntawm lub plhaub ntim txheej tseem yuav ntxiv.
Kev sib tw ib nrab hnub: Lub hom phom no sib xyaw cov txiaj ntsig ntawm corrugated weave thiab braided weave. Qhov kev tshuaj ntsuam no yog tsim rau luam ntawv nrog loj print ntim tab sis qis duab precision.
Qeb peb, cov specifications ntawm cov hlau mesh
Cov specifications ntawm cov hlau mesh feem ntau qhia los ntawm "mesh". Hais txog cov meshes muaj nyob hauv qhov ntev ntawm txhua nti ntawm xaim mesh.
Nyob rau hauv qhov ntev ntawm txhua nti ntawm qhov screen, qhov loj dua cov meshes, lub me me lub aperture ntawm tib lub qhov. Piv txwv, 120 mesh hais txog 120 meshes hauv ib nti ntev ntev ntawm cov hlau mesh; 250 Mesh yog hais txog 250 meshes hauv ib nti ntev ntev hlau mesh. Li ntawd, thiab rau li ntawd.
Cov naj npawb ntawm meshes ib nti ntawm xaim mesh yog tsawg dua 180 mesh, uas muaj peev xwm yuav txawv los ntawm tib neeg qhov muag. Yog hais tias nws ntau tshaj 180 mesh, nws tsis yooj yim rau tib neeg qhov muag pom cov mesh.
Qhov kev tshuaj ntsuam no kuj yog sawv cev los ntawm "qauv" ntawm kev ua lag luam. Piv txwv li, qhov tseeb Mage SP56 yog qhia tias yog ib qho 150 mesh cov xov kabmob mesh, thiab qhov tseeb mesh XX15 yog sawv cev li 50 mesh ob npaug tsab xov paj.
