Desiccant muaj ntau heev hauv lub neej txhua hnub.Feem ntau, koj tuaj yeem yuav qee lub hnab ntim cov txiv ntoo, uas muaj cov desiccant.Lub hom phiaj ntawm desiccant yog txo cov av noo ntawm cov khoom thiab tiv thaiv cov khoom los ntawm deteriorated los ntawm noo noo, yog li cuam tshuam rau qhov zoo ntawm cov khoom.Saj.Txawm hais tias lub luag haujlwm ntawm lub desiccant yog nqus cov av noo hauv cov khoom, cov ntsiab lus ntawm kev siv thiab cov ntaub ntawv sib txawv.Muaj ob hom raws li chemistry thiab physics:
Tshuaj drying agent:
Calcium chloride desiccant
Calcium chloride feem ntau yog ua los ntawm cov khoom siv zoo calcium carbonate thiab hydrochloric acid ua raw khoom.Nws tau refined los ntawm cov tshuaj tiv thaiv synthesis, pom, evaporation, concentration thiab ziab.Nws feem ntau yog siv los ua calcium fortifier, chelate agent, curing agent thiab desiccant hauv kev lag luam zaub mov.Tsis tas li ntawd, nws kuj yog siv los ua ib qho desiccant rau gases.Nws tuaj yeem siv los ua kom qhuav nruab nrab, alkaline lossis acid gases thiab siv los ua lub cev qhuav dej rau kev tsim cov ethers, alcohols, propylene resins, thiab lwm yam Calcium chloride feem ntau ntxeem tau, granular los yog honeycomb khoom, odorless, me ntsis iab saj, soluble. hauv dej thiab tsis muaj xim.
2. Quicklime desiccant
Nws cov khoom tseem ceeb yog calcium oxide, uas ua tiav cov dej nqus los ntawm cov tshuaj tiv thaiv tshuaj, tuaj yeem qhuav nruab nrab lossis alkaline roj, thiab tsis tuaj yeem rov qab los.Feem ntau yog siv cov desiccants hauv "dawb ncuav mog qab zib".Tsis tas li ntawd, nws kuj tseem siv tau rau hauv cov khoom siv hluav taws xob, tawv, khaub ncaws, khau, tshuaj yej, thiab lwm yam, tab sis txij li lub quicklime yog alkali muaj zog, nws yog corrosive heev, thiab thaum lub qhov muag ntawm cov neeg laus thiab cov me nyuam raug mob, yog maj mam raug tshem tawm.
Lub cev desiccant:
Silica gel desiccant
Lub ntsiab tivthaiv yog silica, uas yog granulated los yog beaded los ntawm tej yam ntuj tso minerals.Raws li tus desiccant, nws cov qauv microporous muaj kev sib raug zoo rau cov dej molecules.Qhov zoo tshaj plaws noo noo nqus ib puag ncig rau silica gel yog chav tsev kub (20 ~ 32 ° C) thiab cov av noo siab (60 ~ 90%), uas tuaj yeem txo cov av noo ntawm ib puag ncig txog li 40%.Silica gel desiccant muaj cov yam ntxwv ntawm cov xim tsis muaj xim, tsis muaj ntxhiab thiab tsis muaj tshuaj lom, ruaj khov hauv tshuaj lom neeg thiab zoo dua hauv kev nqus dej noo.Siv dav hauv cov twj paj nruag, cuab yeej, tawv, lub nra, khoom noj, textiles, khoom siv thiab lwm yam.Nws lub luag haujlwm yog los tswj cov av noo ntawm ib puag ncig thaum khaws cia thiab kev thauj mus los kom tsis txhob ya raws, mildew thiab xeb.Nws yog tsim nyog sau cia tias qhov no tsuas yog pom zoo desiccant hauv EU.
3. Av nplaum (montmorillonite) desiccant
Lub ntsej muag zoo li lub pob grey, zoo tshaj plaws rau kev nqus dej noo hauv qhov chaw hauv qab no hauv qab 50 ° C.Yog tias qhov kub thiab txias siab tshaj 50 ° C, qhov degree ntawm "dej tso" ntawm cov av nplaum yog ntau tshaj qhov "dej nqus dej".Tab sis qhov zoo ntawm av nplaum yog tias nws pheej yig.Cov desiccant yog siv dav hauv kev kho mob, ntim khoom noj, khoom siv kho qhov muag, khoom siv hluav taws xob, khoom siv tub rog thiab cov khoom siv pej xeem.Vim tias nws siv cov khoom siv ntshiab ntuj bentonite, nws muaj cov yam ntxwv ntawm cov adsorption muaj zog, ceev ceev adsorption, tsis muaj xim, tsis muaj tshuaj lom, tsis muaj kuab paug ib puag ncig thiab tsis muaj kev sib cuag corrosion.Nws yog ib puag ncig tus phooj ywg, tsis muaj xim thiab tsis muaj tshuaj lom, tsis muaj kev puas tsuaj rau tib neeg lub cev, thiab muaj kev ua haujlwm zoo adsorption.Kev ua haujlwm adsorption, static dehumidification thiab tshem tawm tsw.
