Filter bepa: Innovation iri nyore

Nokuti nguva yokutanga Sefa bepa rinoshandisirwa kutanga muna China yekare, Chokwadi, nokuti chinangwa ichi kushandisa zvatinosiita zvinhu, asi pfungwa dzateyiwa pasi. It Parizvino unobereka kushandiswa mashomanana zvirimwa. Izvi imhaka ndechokuti Sefa bepa, pasinei ayo pachena nyore, chibereko nokuda pagadzirwe raisanganisira zvakawanda rose ruzivo. Kunze cellulose zvigadziko, rine yakakosha fibers uye mishonga, madhayi, Polymers. Filter Paper rakashandiswa wokunatswa mafuta, mafuta uye mhepo inoyerera motokari michini, simba dzakabatana uye injini kuti okurima michina. Pachirehwa kuti inonzwika apo ari gasi turbines, maindasitiri compressors, Diesel njanji nemotokari. Mukuwedzera, Laboratory Sefa bepa inoshandiswa nokuda Analyses yaigadzira zvokudya (shuga, doro uye waini, uye), uyewo dzimwe maindasitiri.

Izvi zvezvinotaurwa paupamhi yokukosha zvivako zviri zvinhu inopiwa neimwe nerudzi rwayo, akagadzirirwa zvakananga kuti imwe chinangwa. Zviratidzi kuvimba kutanga zvinoriumba uye zvakare kushandisa mamiriro. Naizvozvo technologists basa anokonzera pagadzirwe iyi kuitira kuti Sefa bepa hwaienzanirana mumuviri, zvemaziso uye makemikari maitiro kazhinji zvechisimba ezvinhu nayo richashandiswa.

Process kuti mukugadzira nechinangwa kungoipa chaiyo pore mamiriro kuti anopa yakadzika inclusions ose extraneous asunga yakasvinwa magasi uye mvura. Panyaya iyi, iyo Sefa bepa vanofanira imwe simba ehupfumi, izvo zvinoreva kuti ape yunifomu kuparadzira fibers iri acho uye rakadzika impregnation kunobva polymer bhainda nziyo. Mabikirwo ayo kugadzirwa chine zvinhu zvitatu nzendo: kubatana kwetunhu internet nziyo, kubika zvinokosha, impregnation bepa chawo bhainda polymer.

vazhinji yenhengo zvinogona kushandiswa danho rechitatu. Zvisinei, vakawanda styrene-acrylic copolymers (acrylic impregnation), phenol nebwe (phenol) zvinoshandiswa indasitiri ano. Pakutanga pane vakawanda zvakanakira. Kunyanya, ari kugadzirwa pabepa akaiswa mushonga wokuuraya acrylic hapana mamwe kubudiswa danho - kupisa kurapwa, filters akadai uyewo vanoonekwa zvakatipoteredza ushamwari, riri kunyanya kukosha kana mhepo kurapwa. Phenolic impregnation - iyi ndiyo nzira chinyakare kubereka mashoko nokuda Automotive indasitiri. Izvi zvinogona kushandiswa mhando mbiri Inogadzirwa nemasiridzi anobuda mumiti (resol kana novolak) kana wemisanganiswa dzaro. Huru nani zvichienzaniswa novolak resole riri shoma akasununguka phenol kugutsikana.

The Sefa bepa anogona kuiswa mushure nekusimbisa, nebefu kurapwa, uyewo akaturikidzana dzinoverengeka, izvo zvingave zvakasiyana mhuka. kushanda ichi pamusoro rwuchiwanzwa, simba, siyana pakubhadhara entrained inoramba.
