Cov khoom siv tshuaj ntsuam yog tsuas yog siv rau qhov pom ntawm qhov chaw thiab cov khoom siv yog siv rau kev pom tob.Qhov sib txawv yog raws li nram no:
1. Cov khoom siv tshuaj ntsuam (nylon monofilament, hlau monofilament) ncaj qha cuam tshuam cov impurities hauv qhov pom ntawm qhov chaw ntawm cov khoom.Qhov zoo yog tias cov qauv monofilament tuaj yeem ntxuav tau ntau zaus thiab cov nqi noj tsawg;Tab sis qhov tsis zoo yog hom kev pom saum npoo, uas yooj yim ua rau lub ntsej muag txhaws ntawm lub hnab lim.Cov khoom lag luam no yog qhov tsim nyog tshaj plaws rau lub sijhawm lim dej ntxhib uas tsis muaj qhov tseeb, thiab qhov pom tseeb yog 25-1200 μ m.
2. Cov khoom siv Felt (kab koob punched daim ntaub, tov tshuab tsis-woven npuag) yog ib qho sib sib zog nqus peb-dimensional lim khoom, uas yog yus muaj los ntawm xoob fiber ntau qauv thiab siab porosity, uas tsub kom lub peev xwm ntawm impurities.Cov khoom siv fiber ntau no yog nyob rau hauv kev sib cuam tshuam hom, uas yog, qhov loj dua ntawm impurities raug cuam tshuam rau ntawm qhov chaw ntawm cov fiber ntau, thaum cov khoom zoo raug kaw rau hauv cov txheej sib sib zog nqus ntawm cov khoom lim, yog li cov khoom pom muaj ntau dua pom. efficiency, Tsis tas li ntawd, qhov kub thiab txias ntawm qhov chaw kho cua sov, uas yog, daim ntawv thov ntawm instant sintering technology, tuaj yeem tiv thaiv cov fiber ntau los ntawm kev poob vim qhov kev kub ceev ntawm cov kua dej thaum pom;Cov khoom siv tau pov tseg thiab pom qhov tseeb yog 1-200 μm.
Cov khoom tseem ceeb ntawm cov khoom siv lim dej yog raws li hauv qab no:
Polyester - feem ntau siv lim fiber ntau, tshuaj lom neeg zoo, ua haujlwm kub tsawg dua 170-190 ℃
Polypropylene yog siv rau kev lim dej hauv kev lag luam tshuaj.Nws muaj cov kua qaub thiab alkali zoo heev.Nws ua haujlwm kub yog tsawg dua 100-110 ℃
Wool - zoo tiv thaiv hnyav ua haujlwm, tab sis tsis haum rau cov tshuaj tiv thaiv acid, alkali pom
Nilong muaj cov tshuaj tiv thaiv zoo (tshwj tsis yog cov kua qaub), thiab nws qhov ua haujlwm kub yog tsawg dua 170-190 ℃
Fluoride muaj qhov ua haujlwm zoo tshaj plaws ntawm qhov kub thiab txias, thiab kev ua haujlwm kub tsawg dua 250-270 ℃
Kev sib piv ntawm qhov zoo thiab qhov tsis zoo ntawm cov khoom siv lim dej thiab cov khoom lim sib sib zog nqus
Muaj ntau ntau yam khoom siv lim rau lim.Xws li woven hlau mesh, lim ntawv, hlau ntawv, sintered lim caij thiab muaj kev xav, thiab lwm yam. Txawm li cas los xij, raws li nws txoj kev lim dej, nws tuaj yeem muab faib ua ob hom, uas yog hom nto thiab hom tob.
1. Cov khoom siv lim dej
Nto hom lim cov ntaub ntawv tseem hu ua cov khoom lim dej.Nws nto muaj qee qhov geometry, cov micropores tsis sib xws lossis cov channel.Nws yog siv los ntes cov av hauv qhov thaiv cov roj.Cov khoom siv lim dej feem ntau yog dawb los yog twill lim ua los ntawm cov hlau hlau, ntaub fiber ntau lossis lwm yam ntaub ntawv.Nws cov ntsiab lus lim dej zoo ib yam li kev siv lub vijtsam precision.Nws qhov kev lim dej raug nyob ntawm qhov ntev geometric ntawm micropores thiab cov channel.
Qhov zoo ntawm cov khoom siv lim dej: qhov tseeb ntawm qhov tseeb, ntau yam ntawm daim ntawv thov.Ib qho yooj yim los ntxuav, rov siv tau, lub neej ua haujlwm ntev.
Qhov tsis zoo ntawm cov khoom siv lim dej saum npoo yog raws li hauv qab no: me me ntawm cov khoom paug;Vim qhov kev txwv ntawm kev tsim technology, qhov precision yog tsawg dua 10um
2. Cov khoom siv lim dej sib sib zog nqus
Qhov tob hom lim cov ntaub ntawv tseem hu ua sib sib zog nqus hom lim khoom lossis cov khoom siv lim sab hauv.Cov khoom siv lim dej muaj qee qhov tuab, uas tuaj yeem nkag siab tias yog qhov superposition ntawm ntau hom lim dej.Cov channel sab hauv yog tsim los ntawm tsis tu ncua thiab tsis muaj qhov tshwj xeeb ntawm qhov sib sib zog nqus.Thaum cov roj dhau los ntawm cov khoom siv lim, cov av hauv cov roj raug ntes los yog adsorbed ntawm qhov tob sib txawv ntawm cov khoom lim.Yog li mus ua si lub luag hauj lwm ntawm filtration.Cov ntawv lim yog cov khoom siv sib sib zog nqus uas siv hauv hydraulic system.Qhov tseeb yog feem ntau ntawm 3 thiab 20um.
Qhov zoo ntawm cov khoom siv lim dej sib sib zog nqus: cov av loj, lub neej ua haujlwm ntev, muaj peev xwm tshem tawm ntau qhov me me tshaj qhov precision thiab sawb, siab lim precision.
Qhov tsis zoo ntawm qhov tob hom lim khoom: tsis muaj qhov sib txawv ntawm cov khoom lim dej sib txawv.Qhov loj ntawm cov impurity hais tsis tuaj yeem tswj kom raug;Nws yuav luag tsis yooj yim los ntxuav.Feem ntau ntawm lawv yog pov tseg.Kev noj yog loj.
