Perlite yog pob zeb pom nyob rau hauv volcanic eruptions. Nws tsim qhov twg liab-kub lava kov hauv av ntawm cov npoo ntawm nws ntws. Vim lub fact tias cov dej kub ntawm no cools tus ceev tshaj plaws, obsidian yog tsim - volcanic iav. Yav tom ntej, yog tias obsidian raug dej, nws hydrates thiab cov tshuaj perlite tau txais - obsidian hydroxide.

Cov tshuaj muaj pes tsawg leeg ntawm perlite (silicon dioxide, dej, lwm yam khoom) tso cai rau koj kom tau ib hom "pob kws" ntawm qhov kub ntawm 1200 degrees, thaum dej tshuaj nthuav dav, thiab qhov ntim ntawm perlite nce mus txog 20. sij hawm. Nws hloov tawm lub thiaj li hu ua perlite xuab zeb, uas muaj cov yam ntxwv ntawm lub cev. Nws yog fireproof, chemically inert, lub teeb yuag, resistant rau pwm, nas thiab kab mob. Perlite yog cov khoom siv rau kev tsim kho, kev kho mob, roj thiab roj kev lag luam, thiab metallurgy. Nws yog ntse siv ntawm qhov kub thiab txias los ntawmrho tawm 260 rau ntxiv 1000 degrees.

Perlite xuab zeb yog tsuas yog siv rau backfilling kab noj hniav thaum lub sij hawm rwb thaiv tsev ua hauj lwm, thaum lub sij hawm ua tiav cov hauj lwm kom lub suab rwb thaiv tsev (3 cm ntawm perlite hloov 15 cm ntawm cib thiab muab suab nrov absorbing ntawm 51 dB), kom lighten mortars los ntawm ib tug tshwj xeeb lub ntiajteb txawj nqus los yog nce qhov zoo ntawm metallurgical alloys.

Tom qab kev kho qhov kub thiab txias, nthuav dav perlite khaws nws cov khoom mus tas li. Nyob rau hauv tsos, perlite yog ib tug dawb khoom nyob rau hauv granules los ntawm 0.1 mus rau 1.0 cm, muaj ib tug loj ceev ntawm 50-150 kilograms ib cubic meter. Tej zaum yog vim li cas lub npe perlite los ntawm lo lus "pearl" - "pearl" (fr.).

Perlite zoo npaum li cas? Perlite yog 100% ib puag ncig tus phooj ywg khoom. Nws muaj cov additives nyob rau hauv daim ntawv ntawm cov poov tshuaj, sodium, txhuas, hlau, calcium, sodium, uas ua rau nws muaj peev xwm mus ntse siv cov khoom no nyob rau hauv kev ua liaj ua teb, tshwj xeeb tshaj yog nyob rau hauv cov cheeb tsam nrog barren av thiab arid climates. Agroperlite yog siv rau loosening av, ntxiv rau ntau yam substrates, thiab kuj yog ib yam khoom uas khaws cia txog li 600% ntawm cov dej los ntawm nws tus kheej qhov hnyav, uas txo cov irrigation. Perlite rau cov nroj tsuag yog siv hauv kev ua liaj ua teb xws li hydroponics.

Thaum peb noj qee yam, piv txwv li, Dutch zaub lossis txiv pos nphuab (strawberries), peb tsis paub tias lawv tsis tau loj hlob hauv av, tab sis hauv cov thawv uas lawv tau txais.kev daws teeb meem. Thiab ib feem ntawm cov thawv no tau ntim nrog perlite.

Cov lim dej ntau yam yog tsim los ntawm perlite, nrog rau cov sorbents uas muaj qhov nqus tau siab thiab yog li siv los tshem tawm cov dej oily ntawm cov dej, ntxuav cov emissions, txhim kho cov dej haus kom zoo thiab txawm tias thaj chaw radionuclides hauv cov dej. av. Tsis tas li ntawd, cov ntaub ntawv tsim los ntawm nws ua rau nws muaj peev xwm tsim lub tshuab nqus tsev rwb thaiv tsev ntawm cryogenic blocks, suav nrog hauv metallurgy rau kev sib cais ntawm huab cua rau hauv nitrogen thiab oxygen.
