Zvakawanda Sei Iwe Unoziva Nezve Porous Material?

Porous zvinhu zviri kwese kwese, kubva pabhonzo riri mumuviri wako kusvika kune sefa iri mugadziri wako wekofi.

Asi sei chinhu chizere nemakomba chingava chakakosha zvakadaro? Mhinduro iri mukutamba kwakaoma kuri pakati

iyo yakasimba zvinhu pachayo uye yakakura network ye pores mukati mayo. Kupindirana uku kunogadzira zvinhu zvakasiyana

izvo zvakashandura nzvimbo dzakasiyana-siyana semishonga, kuchengetedza simba, uye kunyange kuongorora nzvimbo.

Fungidzira chinhu chakazadzwa netuhomwe tudiki, tunzira tusingaoneki, uye maburi madiki. Izvi hazvisi kuremara

-ndiwo anotsanangura hunhu hweporous zvinhu, uye vanobata kiyi kune inokatyamadza nhamba ye

kufambira mberi mumaindasitiri akasiyana.

Wakambozvibvunza here kuti vazivi vemuchadenga vanofema sei mweya wakachena paInternational Space Station? Kana kuti sei masayendisiti

ingagadzira zvinhu zvekuvaka zvakareruka, zvakasimba here? Mhinduro inogona kukushamisa iwe - zvese zvine chekuita neanoshamisa

nyika ye porous zvinhu. Buck up, uye ngationgororei mune inonakidza sainzi kuseri kweizvi hole-y zvinoshamisa!

Chii Chinonzi Porous Materials?

Pakati pavo, porous zvinhu zvinongori zvinhu zvakazadzwa nemapores - madiki madiki kana voids mukati mechimiro chavo.

Aya maburi anogona kusiyanisa zvakanyanya muhukuru, kubva pamicroscopic nanometers (mabhiriyoni emamita) kusvika kuhombe.

millimeter-sized cavities (zviuru zvemamita). Saizi, chimiro, uye kuti mapores aya akabatana sei ese anotamba a

basa rinokosha pakuona zvinhu zvechinhu.

Kune marudzi maviri makuru e porosity yekufunga nezvayo:

*Open-cell porosity:

Fungidzira chipanje. Ndizvo chaizvo open-cell porosity.Mapores akabatana, achibvumira mvura

kuyerera nyore kuburikidza navo. Masefa ekofi,furo, uye mamwe marudzi emapfupa mienzaniso yezvinhu zvakavhurika-sero.

* Yakavharwa-sero porosity:

Pano, ma pores ari ega mabhuru mukati mechinhu chakasimba, asina kubatana kune mumwe nemumwe. Funga nezve a

pumice stone – izere nemakomba, asi mvura haikwanise kufamba pakati pawo. Polystyrene kurongedza nzungu uye

mamwe matombo anoputika mienzaniso yezvinhu zvakavharwa-sero.

Nekunzwisisa mhando uye hunhu hwechinhu porosity, masayendisiti uye mainjiniya vanogona kugadzira

zvinhu zvekushandisa chaiko. Tichaongorora kuti izvi zvinoitwa sei muchikamu chinotevera!

Mhando dzePorous Material

Nyika yeporous zvinhuyakakura uye inobatanidza huwandu hwakawanda hwezvinhu zvakasikwa uye zvekugadzira.

Heino nzwisa yemamwe marudzi akajairika, akakamurwa zvichienderana nekwaakabva kana kuumbwa kwawo:

Natural Porous Materials:

Rocks uye Minerals:

Sandstone, pumice, uye zeolites mimwe mienzaniso yematombo anogara achingoitika.

Izvi zvinhu zvinowana kushandiswa mukusefa, kuvaka aggregates, uye kunyange katsi tsvina nekuda kwe

*Porosity muzana:

Kukosha uku kunomiririra vhoriyamu yevoids mukati mechinhu chichienzaniswa nehuwandu hwayo. Chikamu chepamusoro chinoratidza chimiro chakavhurika uye chakabatana chepore.

* Permeability:

Ichi chivakwa chinoreva kugona kwechinhu kubvumira zvinwiwa (magasi kana zvinwiwa) kuti zvipfuure nepamapores ayo. Iyo pore saizi, chimiro, uye yekubatanidza zvakanyanya kukanganisa permeability.

Mechanical Properties:

*Simba:

Kuvapo kwema pores dzimwe nguva kunogona kuderedza simba rose rechinhu.

Nekudaro, yakangwara engineering ye pore chimiro inogona kugadzira porous zvinhu ne

zvinoshamisa simba-ku-huremu reshiyo, zvichiita kuti ive yakakosha mukuvakwa kwakareruka.

*Elasticity:

Ichi chivakwa chinotaridza kuti yakawanda sei chinhu chinogona kukanganisa mukushushikana uye kudzokera kwairi

chimiro chayo chepakutanga. Porosity inogona kukanganisa elasticity nenzira dzakaoma, zvichienderana ne

zvinhu uye pore chimiro.

Chemical Properties:

*Reactivity:

Iyo yakakwirira yepamusoro yakagadzirwa nema pores inogona kuita kuti iwedzere kushandiswa kana ichienzaniswa nezvinhu zvisiri-porous.

Izvi zvinobatsira mumashandisirwo akaita secatalysis, uko yakawedzera nzvimbo inosimudzira kuita kwemakemikari.

*Kupokana:

Porous zvinhu zvinogona kugadzirwa kuti zvirambe zvakati zvinhu kana makemikari. Semuyenzaniso,dzimwe porous ceramics

kuratidzira kwakanakisa kupisa kupisa, zvichiita kuti ive yakakodzera kune yakakwirira-tembiricha application.

Nekunzwisisa kupindirana uku kwezvivakwa, masayendisiti uye mainjiniya anogona kugadzira porous zvinhu zve

zvinodikanwa chaizvo. Muchikamu chinotevera, tichaona kuti zvinhu izvi zvinoshandiswa sei mumaindasitiri akasiyana-siyana!

Mabhenefiti uye Zvinetso zvePorous Materials

Porous zvinhu zvinopa yakasarudzika seti yemabhenefiti inoita kuti ive yakakosha mumaindasitiri akasiyana siyana. Heano tarisa mamwe akakosha mabhenefiti:

* Nzvimbo yepamusoro yepamusoro:

Iyo yakaoma network ye pores inogadzira nzvimbo yakakura mukati meiyo vhoriyamu diki. Izvi zvinobatsira kuita senge kusefa, adsorption, uye catalysis, uko yakawedzera nzvimbo yenzvimbo inosimudzira kudyidzana pakati pezvinhu uye zvinwiwa / magasi.

*Kureruka:

Nekuda kwekuvapo kwepores, porous zvinhu zvinowanzoreruka pane avo asiri-porous vamwe. Izvi zvakakosha mumashandisirwo akaita seaerospace engineering uye mota-dzinoshanda mafuta uko kudzikisa huremu chiri chinangwa chikuru.

* Inodzorwa kuyerera zvivakwa:

Saizi, chimiro, uye kubatana kwepores zvinogona kugadzirwa kudzora kuti mvura inoyerera sei kuburikidza nezvinhu. Izvi zvinogonesa kunyatsosefa, kudzorwa kwezvinodhaka kuendesa, uye kupatsanurwa kwakanaka kwegasi.

* Tailorable zvivakwa:

Yakasiyana-siyana yemidziyo inogona kugadzirwa porous, uye iyo pore chimiro pachayo inogona kugadzirwa kuti iwane chaiyo zvivakwa. Izvi zvakasiyana-siyana zvinobvumira masayendisiti kugadzira zvinhu zvekushandisa kwakasiyana.

Zvisinei, porous zvinhu zvinouyawo nemamwe matambudziko:

*Simba:

Kuvapo kwema pores kunogona kuderedza simba rose rechinhu. Kuderedza izvi kunoda kunyatsogadzira uye kugadzirisa maitiro.

*Kutsemuka:

Mapores anogona kuita senge stress yekusimbisa mapoinzi, ichiita kuti zvinhu zvinyanye kutsemuka kana kutyoka pasi pekumanikidzwa kwakanyanya.

*Kugadzira kuomarara:

Kugadzira inodiwa pore chimiro inogona kuve yakaoma uye inoda nyanzvi yekugadzira matekiniki, ayo anogona kuwedzera mutengo.

Kushandiswa Kwakakosha KweSintered Stainless Steel Porous Materials

Sintered Stainless simbiporous zvinhu imhando chaiyo ye porous zvinhu zvine zvakasarudzika zvakanakira:

*Kusimba kukuru uye kusimba:

Sintering, nzira yekugadzira, inogadzira zvisungo zvakasimba pakati pesimbi isina tsvina, zvichiita kuti zvive zvakasimba uye zvinogara kwenguva refu.

*Corrosion resistance:

Simbi isina simbi inopa yakanakisa kuramba ngura, ichiita kuti zvinhu izvi zvive zvakanaka kune dzakaoma nharaunda kana maapplication anosanganisira zvinwiwa.
*Biocompatibility: Mamwe mamakisi esimbi isina tsvina anowirirana, zvichireva kuti anogona kuiswa zvakachengeteka mumuviri wemunhu. Izvi zvinovhura mikova ye biomedical application senge mafirita kana bhonzo implants.

* Yakagadzirirwa pore chimiro:

Saizi uye kugovera pores mu sintered Stainless simbi inogona kudzorwa, ichibvumira kukwenenzverwa chaiko kana kugovera kwemvura.

Izvi zvivakwa zvinogadzira sintered Stainless simbi porous zvinhu zvakakosha mumashandisirwo akasiyana siyana, kusanganisira:

*Kusefa:

Iwo anoshandiswa zvakanyanya mumaindasitiri mafirita ezvinwiwa nemagasi, kunyanya mumashandisirwo anoda simba repamusoro uye kusimba.

*Kugovera kwemvura:

Yadzo inodzorwa porosity inobvumira kunyange kugoverwa kwemvura mumatanho senge chromatography kana masero emafuta.

*Silencers:

Iyo yakaoma pore dhizaini inogona kunyatso kunyorovesa masaisai eruzha, ichiita kuti ishande mukushandisa kuderedza ruzha.

*Biomedical implants:

Iyo biocompatible chimiro chemamwe mamakisi inoita kuti ive yakakodzera kuisirwa bhonzo kana dhizaini yekuendesa zvinodhaka.

Iko kusanganiswa kwesimba rakakwirira, corrosion resistance, uye inoturika pore chimiro inoita sintered Stainless simbi porous zvinhu zvakakosha mukushandisa kwakasiyana-siyana kunoda.
