Qhov sib txawv ntawm qhov pom hauv dej thiab pom tob

Cov khoom siv tshuaj ntsuam feem ntau yog siv rau kev lim dej saum npoo thiab xav tias cov khoom siv rau kev pom tob. Qhov sib txawv yog raws li hauv qab no:

1. Cov khoom siv tshuaj ntsuam (nylon monofilament, hlau monofilament) ncaj qha cuam tshuam cov khoom tsis huv hauv qhov pom ntawm cov khoom siv. Qhov zoo yog tias cov qauv monofilament tuaj yeem ntxuav tau ntau zaus thiab kev siv tus nqi qis; Tab sis qhov tsis zoo yog hom lim dej saum npoo av, uas yog ib qho yooj yim ua rau qhov txhaws ntawm lub hnab lim. Hom khoom no yog qhov tsim nyog tshaj plaws rau qhov ntxhib pom lub sijhawm uas tsis muaj qhov tseeb, thiab pom qhov tseeb yog 25-1200 μ m。

2. Felt cov ntaub ntawv (rab koob punched daim ntaub, tshuaj blown non-woven npuag) yog ib qho sib sib zog nqus peb-dimensional lim khoom, uas yog tus yam ntxwv xoob fiber ntau qauv thiab porosity siab, uas ua rau lub peev xwm ntawm impurities. Hom khoom siv fiber ntau no yog rau hom kev cuam tshuam, uas yog, qhov loj dua ntawm cov khoom tsis huv raug cuam tshuam ntawm cov nplaim hluavtaws, thaum cov khoom zoo raug daig hauv cov txheej tob ntawm cov khoom lim, yog li pom tau pom ntau dua Kev ua haujlwm tau zoo, Ntxiv rau, kev kho cua sov saum npoo kub, uas yog, kev siv cov tshuab ua kom sai sai, tuaj yeem tiv thaiv cov fiber ntau los ntawm kev poob vim qhov cuam tshuam nrawm ntawm cov kua thaum pom; Cov khoom siv xav tau pov tseg thiab pom qhov tseeb yog 1-200 μ m

Cov khoom siv tseem ceeb ntawm cov lim dej muaj raws li hauv qab no:

Polyester-feem ntau siv lim cov lim dej, tshuaj lom neeg ua haujlwm 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 qhov kub ua haujlwm tsawg dua 100-110 ℃

Ntaub plaub tsiaj - zoo tiv thaiv kuab muaj nuj nqi, tab sis tsis haum rau anti acid, alkali pom

Nilong muaj tshuaj tiv thaiv zoo (tshwj tsis yog kua qaub), thiab nws qhov kub ua haujlwm tsawg dua 170-190 ℃

Fluoride muaj qhov ua haujlwm zoo tshaj plaws ntawm kev tiv thaiv kub thiab tshuaj lom neeg ua haujlwm, thiab qhov kub ua haujlwm tsawg dua 250-270 ℃

Kev sib piv ntawm qhov zoo thiab qhov tsis zoo ntawm cov khoom lim dej thiab cov lim dej sib sib zog nqus

Muaj ntau yam khoom siv lim rau lim. Xws li xaim xaim xaim mesh, lim ntawv, ntawv hlau, sintered lim lim thiab hnov, thiab lwm yam.

1. Cov khoom lim dej nto
Cov khoom lim dej saum npoo av kuj tseem hu ua cov khoom lim lim. Nws cov nplaim muaj qee qhov geometry, zoo ib yam micropores lossis raws. Nws yog siv los ntes cov av hauv qhov thaiv cov roj. Cov khoom siv lim feem ntau yog tiaj lossis twill lim ua los ntawm cov hlau hlau, ntaub fiber lossis lwm yam ntaub ntawv. Nws txoj cai lim dej zoo ib yam li kev siv lub vijtsam raug. Nws qhov kev lim dej raug nyob ntawm qhov ntsuas qhov ntev ntawm micropores thiab raws.

Qhov zoo ntawm cov khoom lim lim dej: qhia qhov tseeb ntawm qhov tseeb, ntau yam kev thov. Yooj yim los ntxuav, rov siv tau, lub neej ua haujlwm ntev.

Qhov tsis zoo ntawm cov khoom lim dej saum npoo av muaj raws li hauv qab no: cov tshuaj muaj kab mob tsawg; Vim yog qhov txwv ntawm kev tsim thev naus laus zis, qhov tseeb yog tsawg dua 10um

2. Cov khoom lim dej sib sib zog nqus
Qhov tob hom lim cov khoom tseem hu ua sib sib zog nqus cov khoom lim lossis cov khoom lim sab hauv. Cov khoom siv lim tau muaj qee qhov tuab, uas tuaj yeem nkag siab tias yog qhov ua tau zoo ntawm ntau hom lim dej. Cov channel sab hauv yog tsim los ntawm tsis muaj ib txwm muaj thiab tsis muaj qhov loj me ntawm qhov sib txawv sib sib zog nqus. Thaum cov roj hla dhau cov khoom lim, cov av hauv cov roj raug ntes lossis nqus tau ntawm qhov sib txawv ntawm cov khoom lim. Yog li los ua lub luag haujlwm ntawm kev lim dej. Cov ntawv lim dej yog cov khoom siv lim sib sib zog nqus uas siv hauv cov txheej txheem hydraulic. Qhov tseeb yog feem ntau ntawm 3 thiab 20um.

Qhov zoo ntawm cov khoom sib sib zog nqus lim: cov av ntau, ua haujlwm ntev, tuaj yeem tshem ntau qhov me me tshaj qhov ua tau zoo thiab kab txaij, siab lim dej kom raug.

Qhov tsis zoo ntawm qhov tob hom lim cov khoom siv: tsis muaj qhov sib txawv me me ntawm lim cov khoom sib txawv. Qhov loj ntawm cov khoom tsis huv tuaj yeem tswj tsis tau; Nws yuav luag tsis tuaj yeem ntxuav. Lawv feem ntau yog pov tseg. Kev noj yog loj.
