Dab tsi yog cov ntawv thov ntawm fiberglass hauv kev lag luam papermaking?

Fiberglass yog ib yam tshiab ntawm inorganic non{0}}cov khoom siv hlau. Nws yog tsim los ntawm ntuj ores xws li kaolin, pyrophyllite, quartz xuab zeb thiab limestone. Ua raws li cov qauv tshwj xeeb, cov ntaub ntawv tau dhau los ua ntau yam txheej txheem suav nrog siab - kub melting, hlau kos duab thiab twisting. Qhov txoj kab uas hla ntawm ib qho filament yog los ntawm ntau lub micrometers mus rau ntau tshaj nees nkaum micrometers, sib npaug li 1/20 txog 1/5 ntawm tib neeg cov plaub hau. Txhua strand ntawm thawj fiber ntau muaj ntau pua lossis ntau txhiab tus tib filaments.

 

Fiberglass muaj cov yam ntxwv zoo xws li kub tsis kam, zoo heev corrosion kuj, tsis tshua muaj noo noo nqus thiab zoo hluav taws xob rwb thaiv tsev. Nws yog dav siv los ua cov ntaub ntawv txhawb zog, cov khoom siv hluav taws xob rwb thaiv tsev, cov ntaub ntawv thermal rwb thaiv tsev thiab cov khoom siv hluav taws xob hauv cov khoom sib xyaw. Muaj ntau yam kev faib tawm rau fiberglass, uas feem ntau yog raws li cov iav muaj pes tsawg leeg, ib txoj kab uas hla, fiberglass tsos thiab cov yam ntxwv fiber ntau.

 

Raws li ib yam ntawm cov ntawv muaj, fiberglass ntawv feem ntau yog siv rau kev pom, suab haum, thermal rwb thaiv tsev thiab hluav taws xob rwb thaiv tsev. Nws yog ua los ntawm ultra- fiberglass zoo, featuring nplaim tsis kam, tshuaj tiv thaiv thiab superior seem stability.

 

Daim ntawv no tuaj yeem tsim rau ntawm Foursdrinier lossis lub tog raj kheej lub tshuab ua ob txoj kev: ib qho yog siv 100% fiberglass (filament txoj kab uas hla hauv qab 0.3 ~ 0.5μm) nrog lub teeb ntaus thiab nplaum ntxiv; lwm qhov yog blending fiberglass nrog ib nrab chemical wood pulp. Silica gel los yog colloidal alumina kuj tuaj yeem muab ntxiv los txhim kho daim ntawv muaj zog. Nws cov txheej txheem ntau lawm yog yooj yim dua li cov pa papermaking. Fiberglass tsuas yog yuav tsum tau dispersed es tsis txhob raug ntaus, thiab tsis tas yuav tsum nias thaum lub sij hawm tsim ntawv.

 

Cov roj teeb cais yog cov khoom tseem ceeb ntawm cov roj teeb cia. Rau cov hlau lead-acid roj teeb, cov khoom sib cais yuav tsum muaj hluav taws xob tsis zoo, muaj zog acid thiab oxidation tsis kam, siab porosity nrog me me pores, homogeneous qauv thiab zoo elasticity. Lawv ua kom muaj kev sib kis ion dawb thaum tiv thaiv luv luv ntawm daim hlau electrode.

 

Cov khoom siv roj hmab ib txwm siv rau cov hlau lead-acid roj teeb tuaj yeem ua tau raws li qhov yuav tsum tau ua hauv kev ua tau zoo, tab sis lawv muaj lub voj voog ntev ntev thiab cov nqi siab. Lawv lub neej kev pab cuam tsis sib xws nrog lwm cov roj teeb, vim tias ib txheej ntawm cov roj hmab sib cais tuaj yeem rov siv tau rau 2 mus rau 3 lub roj teeb, ua rau cov khoom pov tseg.

 

Fiber Composite Separators khav theeb ntau cov khoom siv raw, cov nqi qis, thiab txhawb nqa lub thinning ntawm roj teeb electrode daim hlau. Lawv tau txais kev pom zoo txawv teb chaws los hloov cov roj hmab sib cais. Lub fiberglass sib cais yog tsim los ntawm fiberglass lev thiab fiberglass lev sib txuas nrog cov nplaum. Lub fiberglass lev tiv thaiv cov fiber ntau cais los ntawm oxidative corrosion los ntawm qhov zoo electrodes thiab tiv thaiv luv luv Circuit Court tshwm sim los ntawm ntog active tshuaj ntawm electrode daim hlau.

 

Cov ntaub ntawv rwb thaiv tsev ua los ntawm cov nroj tsuag fibers tsis tuaj yeem ua tau raws li kev lag luam siab - qhov yuav tsum tau ua rau qhov kub thiab txias. Yog li ntawd, siab - ntawv rwb thaiv tsev ntawv thiab cov ntawv ua haujlwm yog tsim los ntawm cov ntaub ntub dej, sib xyaw cov tshuaj fiber ntau nrog cov khoom zoo insulating (xws li polyester fiber thiab polysulfone fiber) thiab ib feem me me ntawm fiberglass.
