Silica Gel Desiccant Silicone desiccant cov yam ntxwv, silica gel desiccant yog ib yam khoom ua muaj mob adsorption, cov tshuaj ntawm cov tsis muaj zog, feem ntau tsuas yog ntsev thiab sodium silicate thiab sulfuric acid, cov laus, cov tshuaj lom neeg kab mob thiab lwm yam kev ua tiav nws thiaj li tsim nyog. Cov tshuaj formula ntawm silica gel mSiO2. NH2O, amorphous tshuaj, insoluble nyob rau hauv dej thiab lwm yam ntim, tshuaj stability, tsis muaj tshuaj lom thiab tsis qab, ntxiv rau alkali thiab hydrofluoric acid, feem ntau tsis hnov mob nrog lwm yam tshuaj. Cov tshuaj lom neeg thiab lub cev ntawm cov kua roj ntawm cov kua tshuaj yog txiav txim siab tias cov khoom siv tsis tu ncua ntawm nws cov khoom yog qhov yooj yim los hloov. Xws li: ruaj khov khoom, ruaj khov tshuab, zoo thermal stability, zoo adsorption.
Silica porous pawg muab faib rau: nplua silica gel, B hom silicone, macroporous silica gel, coarse silica gel, thiab lwm yam, vim hais tias lawv cov adsorption tsis yog tib yam, lawv cov yam ntxwv adsorption txawv. Porous silica gel yog rau cov neeg tsis muaj humidity, lub peev xwm adsorption siab tshaj qhov kev tswj cov kev cai, ob tus neeg siab puag ncig ib puag ncig, tus yam ntxwv ntawm kev sib npaug tswj lub cev tshaj cov yam ntxwv ntawm cov pore pore pliav yog zoo dua.
Silica Gel Desiccant B-hom silica gel yog feem ntau ntawm cov coarse thiab me me silica gel, tus nqi ntawm adsorption kuj yog nruab nrab ntawm ob. Loose silica gel yog feem ntau yog siv rau hauv cov ntaub ntawv pov thawj, tus neeg matting, cov tshuaj txhuam hniav ntxhib khoom, raws li kev siv ntau lub hom phiaj, rau saum toj no silica gel desiccant siv ntau tshaj
Silicone desiccant muaj lub zog adsorption muaj peev xwm, cov tawv nqaij ntawm tib neeg tuaj yeem tsim cov nyhuv qhuav, yog li ntawd, lub lag luam yuav tsum hnav ib lub Hoobkas zoo. Yog hais tias lub silicone mus rau hauv ob lub qhov muag, yuav tsum siv ntau cov dej ntxuav, thiab sai li sai tau mus nrhiav kev kho mob. Silicone desiccant nws tus kheej yog ib qho khoom nruab nrab, ntxiv rau muaj zog alkali, muaj zog acid hauv qee yam mob hauv cov tshuaj tiv thaiv, tsis nrog lwm yam tshuaj tua. Nyob rau tib lub sij hawm, silicone tseem tsuas yog ntawv pov thawj los ntawm US FDA, nrog cov tshuaj, cov zaub mov ncaj qha mus kov kev siv cov khoom noj. Cov nram qab no yog tib yam li "
Silicone desiccant attack tom qab noj mov, tsis tas yuav loj. Nws yuav tsis tsim kev puas tsuaj rau tib neeg lub cev, nws yuav tsis raug los ntawm lub cev. Tom qab qhov pib noj tau haus tau ib co mis nyuj, yog li ntawd lub silicone desiccant yuav sai sai no yuav tawm nrog tib neeg lub cev quav.
Silicone rov
Silica gel nyob rau hauv cov chav kawm ntawm tus txheej txheem, vim adsorption ntawm cov xov xwm nyob rau hauv cov dej vapor los yog lwm yam organic teeb meem, peev xwm adsorption decreased, yuav rov qab siv tom qab kev txhim kho.
(1) Silicone adsorption ntawm dej pa tom qab tus tsim dua tshiab.
(2) Silicone adsorption ntawm cov organic impurities tom qab tus tsim dua tshiab.
(3) silicone regeneration yuav tsum them nyiaj rau qhov teeb meem:
Silica Gel Desiccant Kev tsim dua tshiab yuav tsum tau ceev faj kom paub cov tshuaj qis qis dua, kom tsis txhob muaj qhov qaug zog vim muaj silicon feem ntau tawg, txo qhov rov ua haujlwm.
Silica gel kua qab rog, qhov kub kub dhau lawm yuav ua rau kev hloov pauv ntawm cov pob zeb ntawm cov pob zeb silicone thiab txo nws cov nyhuv adsorption, cuam tshuam rau kev siv tus nqi. Rau cov yeeb yam xiav yas los sis cov kua roj (silica) silica, yuav tsum tsis txhob muaj tshaj 120 ℃, txwv tsis pub nws yuav yog vim muaj cov pa oxidation ntawm tus tsim tawm thiab poob xim. Cov tshuaj ziab dua tshiab yuav tsum tau siav kom tshem cov ntaub zoo kom thiaj li hais tias cov hom phiaj yog homogeneous.
