Desiccant tseem hu ua kev lag luam nqus. Nws siv los tiv thaiv kom ya raws thiab qis qis thiab ua si lub luag haujlwm ziab. Desiccant yog ib hom dej tshem tawm tus neeg sawv cev uas nqus cov dej noo ntawm cov pa. Nws lub hauv paus ntsiab lus ziab yog lub cev adsorb dej lwg me me hauv nws tus kheej cov qauv lossis kev nqus tshuaj kom nqus cov dej molecules thiab hloov lawv cov qauv tshuaj ua kom dhau los ua lwm yam khoom tawm. )
Cov desiccants uas siv adsorption kom tshem tawm cov pa dej muaj xws li silica gel, alumina gel, cov tshuaj tua molecular, cov roj carbon activated, pob txha pob, hluav ncaig lossis cov av nplaum lossis lwm yam, thiab lwm yam.
Feem ntau siv cov desiccants kom tshem tawm cov dej vapor los ntawm kev nqus tshuaj lom neeg muaj xws li calcium chloride, quicklime lossis phosphorus pentoxide, uas muaj cov chemical siab nrog dej vapor.
Tam sim no muaj tsib yam khoom lag luam desiccant hauv kev lag luam desiccant:
1) Silica gel desiccant-lub ntsiab lus tseem ceeb yog silica, uas yog kev ua kom huv thiab ua tiav los ntawm cov khoom ntuj tsim ua granules lossis hlaws dai. Raws li desiccant, nws cov qauv microporous (nruab nrab 2A) muaj kev sib txuam zoo rau cov dej dej lwg me me. Cov kev tsim nyog huv hygroscopic ib puag ncig rau silica gel yog chav sov (20 ~ 32) thiab cov av noo (60 ~ 90%). Nws tuaj yeem txo qhov ntsuas av noo ntawm qhov chaw nyob ib puag ncig mus txog 40%. Silica gel muaj qhov tso tawm adsorption muaj zog thiab tuaj yeem tsim kom muaj cov nyhuv qhuav ntawm tib neeg daim tawv nqaij. Yog li, koj yuav tsum hnav khaub ncaws ua haujlwm thaum ua haujlwm. Yog tias silica gel nkag mus rau hauv lub qhov muag, yaug nrog dej kom ntau thiab nrhiav kev kho mob kom sai li sai tau.
2) Clay desiccant (montmorillonite) -Qhov cov tsos yog pob txho me me, uas yog qhov tsim nyog rau nqus cov dej noo hauv ib puag ncig qis dua 50 ° C. Thaum twg qhov kub ua haujlwm siab dua 50 ℃, cov degree ntawm" dej tso tawm" ntawm cov av nplaum yog ntau dua li cov" dej nqus" ;. Tab sis qhov zoo ntawm cov av nplaum dag hauv nws tus nqi qis.
3) Molecular sieve desiccant-nws yog cov khoom siv hluavtaws desiccant nrog cov muaj zog adsorption rau dej lwg me me. Qhov pore loj ntawm lub suab sib molecular tuaj yeem tswj los ntawm kev siv tshuab sib txawv. Ntxiv nrog rau adsorbing dej tso pa, nws kuj tseem tuaj yeem adsorb lwm cov roj av. Xws li qhov kub siab dhau 230 ℃, nws tseem tuaj yeem tuav cov dej molecules. Qhov zoo: muaj zog adaptability. Qhov tsis zoo: qhov nqus noo tsawg npaum li cas, kev tiv thaiv ib puag ncig tsis zoo (tsis xeb).
4) Cov ntxhia hauv dej-nws muaj li ntawm ntau yam khoom ntuj tsim, thiab cov tsos zoo li tshem tawm dawb pob me. Nws yog non-toxic thiab tsis muaj mob, thiab yog ib qho chaw tsis zoo hauv kev nyiam cov khoom lag luam ib puag ncig. Qhov ntsuas kev nqus noo yog ntau dua 50%, uas yog ob zaug ntawm qhov tseeb ntawm silica gel.
5) fiber ntau desiccant-yog ua los ntawm cov ntshiab ntuj cog fiber ntau los ntawm kev ua tiav cov khoom siv tshwj xeeb. Ntawm lawv, zaj duab xis-txheej fiber ntau desiccant daim ntawv yooj yim thiab cov tswv yim, thiab tsis siv qhov chaw. Nws lub peev xwm nqus dej muaj peev xwm ncav cuag 100% ntawm nws tus kheej qhov hnyav, uas yog qhov tsis tau ntawm qhov tsis zoo ntawm desiccants. Ib qho ntxiv, cov khoom lag luam muaj kev nyab xeeb thiab huv si, thiab tus nqi tau muaj nrab. Nws yog qhov kev xaiv zoo tshaj plaws rau ntau yam khoom siv roj ntsha, khoom noj qab haus huv thiab tshuaj.
Kev ceev ceev ntawm desiccant
Lub ntsiab ntawm cov quicklime desiccant yog calcium oxide, thiab nws lub peev xwm nqus dej tau tiav los ntawm kev siv tshuaj lom neeg, yog li dej tsis tuaj yeem hloov pauv tau. Tsis hais txog qhov ntsuas cua ntawm qhov chaw sab nraud, nws tuaj yeem tswj lub peev txheej noo noo ntau dua 35% ntawm nws tus kheej qhov hnyav, thiab zoo dua rau qhov tsis tshua kub-cia. Nws muaj qhov ua kom zoo qhuav thiab noo noo nqus cov nyhuv thiab yog tus nqi tsawg. Nws tuaj yeem siv dav hauv cov zaub mov, khaub ncaws, tshuaj yej, tawv, khau raj, khoom siv hluav taws xob thiab lwm yam lag luam.
CHUNWANG tau mob siab rau cov dej noo txij thaum 1998, tau ntawv pov thawj los ntawm ISO14001: 2015, ISO9001: 2015, BSCI, GMP, SGS, Walmart audit, USAFDA DMF, EU Ncav, Duns kev sau npe. Yog tias muaj kev pabcuam xav tau, thov hu rau hauv qab no:
