MaDesiccants anoita basa rakakosha mukuchengetedza kunaka kwechigadzirwa uye kugadzikana nekutora hunyoro uye kurwisa zvinhu zvakaita sekuora, mold, uye kuderedzwa kunokonzerwa nehunyoro. Muchikamu chino, tichatarisa zvakanyanya kune maviri anozivikanwa desiccants - activated alumina uye silica gel, tichiongorora maitiro avo akasiyana, mabhenefiti, uye miganhu.
Activated alumina imhando ine porous yakanyanya yealuminium oxide inozivikanwa neayo adsorption zvimiro. Inoshandiswa zvakanyanya mumaindasitiri ekuomesa maapplication nekuda kwekugona kwayo kubvisa hunyoro kubva kumhepo nemagasi. Nzvimbo yaro yakakura uye yakakwirira porosity inoita kuti ive desiccant inoshanda yekuchengetedza mhando yezvigadzirwa zvinonzwisisika zvakadai semishonga, zvemagetsi, uye makemikari. Nekudaro, chimwe chezvipimo zveakamisikidzwa alumina ndechekuti inogona kuburitsa huwandu hwakakosha hwekupisa panguva yeadsorption process, iyo inogona kunge isina kukodzera kune mamwe maapplication.
Kune rimwe divi, silica gel is synthetic desiccant iyo inogadzirwa kubva kusilicon dioxide. Iyo inozivikanwa nenzvimbo yayo yepamusoro uye hukama hwakasimba hwemamorekuru emvura, zvichiita kuti ive inoshanda mwando adsorbent. Silica gel inowanzo wanikwa mumapakiti mukati mekurongedza kwechigadzirwa kuchengetedza zvinhu zvakawoma uye zvisina kukuvara kwehunyoro. Inoshandiswawo kuchengetedza zvigadzirwa zvemagetsi, makamera, uye zvinhu zvedehwe panguva yekuchengetedza uye yekufambisa. Pasinei nekushanda kwayo, silica gel ine mashoma adsorption kugona uye ingangoda kutsiviwa kana kuvandudzwa kazhinji.
Ose ari maviri akabatidzwa alumina uye silica gel ane masimba avo uye kushaya simba kana zvasvika pakunyorova adsorption. Nepo alumina yakashongedzwa ichinyanya kukodzera kuomeswa kwemaindasitiri uye hukuru-hukuru kunyorera, silica gel inokodzera zvirinani zvigadzirwa zvidiki, zvakatetepa. Kunzwisisa hunhu hwakasiyana hweaya ma desiccants kwakakosha pakusarudza iyo yakakodzera kune chaiyo yakanangana nehunyoro nyaya.
Pamusoro pemaitiro avo akasiyana, ese ma desiccants ane nzira dzakasiyana dzekunyorova adsorption. Activated alumina inoshanda kuburikidza nemaitiro anozivikanwa se physisorption, apo mamorekuru emvura anoshambadzwa nemuviri pamusoro pe desiccant. Kune rimwe divi, silica gel inoshandisa musanganiswa wekushambadza kwemuviri uye capillary condensation kuteya unyoro mukati mepores ayo. Kunzwisisa maitiro aya kwakakosha pakugadzirisa mashandiro e desiccants mumashandisirwo akasiyana.
Uyezve, idzi desiccants dzinowana kushandiswa kwakapararira mumaindasitiri akasiyana. Activated alumina inoshandiswa zvakanyanya mukuomeswa kwemhepo yakamanikidzwa uye magasi, pamwe nekucheneswa kwezvinwiwa zvakaita sepropane uye butane. Inoshandiswawo mukuomeswa kwezvinonyungudutsa uye mukubvisa tsvina kubva gasi rechisikigo. Silica gel, kune rumwe rutivi, inowanzoshandiswa kudzivirira midziyo yemagetsi inodzikama, kudzivirira ngura uye ngura mupfuti, uye kuchengetedza magwaro akakosha nemifananidzo.
Mukupedzisa, ese ari maviri akamiswa alumina uye silica gel desiccants anoita basa rakakosha mukuchengetedza kunaka kwechigadzirwa uye kugadzikana nekupikisa nyaya dzine chekuita nehunyoro. Imwe neimwe desiccant ine yayo yakasarudzika hunhu, mabhenefiti, uye zvisingakwanisi, zvichiita kuti ive yakakodzera kune akasiyana maapplication. Kunzwisisa zvimiro, maitiro ekunyorova adsorption, uye mashandisirwo eaya ma desiccants akakosha pakushandisa zvinobudirira mumaindasitiri akasiyana. Kunyangwe iri kuomesa maindasitiri kana kuchengetedza zvemagetsi, iyo desiccant yakakodzera inogona kuita mutsauko wakakura mukuchengetedza chigadzirwa kutendeseka uye kunaka.
