Categorized los ntawm cov theem, vermiculite tuaj yeem muab faib ua cov neeg tsis raug cai vermiculite thiab nthuav dav vermiculite. Categorized los ntawm cov xim, nws tuaj yeem faib ua xim kub thiab nyiaj (kaus ntxhw). Vermiculite muaj cov khoom zoo xws li kub rwb thaiv tsev, tiv thaiv txias, tiv thaiv kab mob, tiv thaiv hluav taws, nqus dej thiab lub suab nqus, thiab lwm yam thaum ci rau 0.5 ~ 1.0 feeb nyob rau hauv 800 ~ 1000 ℃, nws lub ntim tuaj yeem nce nrawm dua 8 txog 15 lub sij hawm, txog 30 zaug, nrog cov xim hloov mus rau hauv kub lossis nyiaj, tsim cov xoob xaim nthuav dav vermiculite uas tsis yog los tiv thaiv cov kua qaub thiab tsis zoo hauv kev ua hluav taws xob. Vermiculite tom qab cov txheej txheem nthuav dav yuav siv rau txheej faus nchav, nrog cov feem ntau yog 100-200kg / m³ (Vim tias qhov ntau ntau ntawm vermiculite nthuav dav, kev thauj tus nqi yuav yog qhov loj heev, yog li cov xa tawm vermiculite feem ntau yog hom tsis tau) Cov.

Daim ntawv thov ntawm Vermiculite

Hauv kev ua liaj ua teb, vermiculite tuaj yeem siv cov av txias, vim nws cov cation pauv thiab nqus, txhim kho av qauv, dej cia thiab av noo, tsim cov av permeability thiab dej cov ntsiab lus, ua kom cov av acid hloov mus rau hauv nruab nrab av; vermiculite tseem tuaj yeem ua lub luag haujlwm tsis zoo, hinering hloov pauv sai ntawm PH tus nqi, ua rau cov chiv tso tawm qeeb hauv kev cog qoob loo nruab nrab, thiab tso cai rau kev siv me ntsis ntawm kev siv chiv rau tsob ntoo tab sis tsis muaj teeb meem. Vermiculite tseem tuaj yeem muab rau cov qoob loo nws tus kheej muaj cov K, Mg, Ca, Fe, thiab cov nyiaj ntawm cov ntsiab lus ntawm Cu, Zu. Raws li kev nqus, cation txauv thiab tshuaj lom neeg muaj pes tsawg leeg cov yam ntxwv ntawm vermiculite, yog li nws ua si chiv kev tu, dej tuav, dej cia, permeability thiab ntxhia chiv, thiab lwm yam ntau lub luag haujlwm. Cov kev ntsuas pom: tso 0.5-1% nthuav dav vermiculite sib xyaw rau hauv fertilize, ua kom cov qoob loo yauv los ntawm 15-20%.

Hauv kev cog vaj, vermiculite tuaj yeem siv rau cov paj, zaub, txiv hmab txiv ntoo cog qoob loo, yug me nyuam thiab lwm yam, ntxiv rau cov av av thiab cov neeg tswj hwm, tab sis kuj siv rau cov kab lis kev cai. Raws li yuav tsum yog khoom noj khoom haus nyom-keeb kwm rau cog potted ntoo thiab coj mus muag seedbed, nws yog qhov zoo dua ntawm kev hloov thiab thauj cov nroj tsuag. Vermiculite tuaj yeem txhawb nqa cov hauv paus hniav cog kev loj hlob thiab cov noob kev loj hlob, tuaj yeem muab dej thiab khoom noj khoom haus ntawm cov nroj tsuag zuj zus mus ntev, thiab ua kom cov hauv paus cag txias tuaj. Vermiculite tuaj yeem ua rau cov nroj tsuag muaj dej txaus thiab ntxhia pob zeb nyob rau theem pib, txhawb cov nroj tsuag kom nrawm dua, thiab nce ntau lawm.

Nthuav cov vermiculite, nteg rau saum ru tsev, yuav ua si lub ntog zoo zoo ntawm cov cua sov, ua kom lub tsev sov nyob rau lub caij ntuj no thiab txias txias rau lub caij ntuj sov. Siv cov vermiculite cib mus rau hauv cov phab ntsa muab faib tawm ntawm qhov nce siab lossis siv cov vermiculite block raws li cov khoom faib rau hauv tsev so lossis chaw lom ze, cuam tshuam los ntawm lub suab nqus, pov thawj hluav taws, kev tiv thaiv kub thiab lwm yam yuav ua rau pom zoo thiab lub tsev tseem yuav txo nws txoj kev thauj Cov.

Cov huab cua me me ua cov ntaub ntawv tom qab qhov sib xyaw ntawm qhov chaw nres nkoj kom nthuav dav, ua kom cov vermiculite nthuav dav ua cov khoom ntxig suab rwb thaiv tsev. Thaum qhov zaus yog 2000C / S, lub suab--raug tus nqi ntawm 5 hli tuab vermiculite yog 63%, 6mm 84% thiab 8mm 90%.

Vermiculite yog qhov zoo heev rau qhov tiv taus huab cua vim nws lub peev xwm thiab lub zog tseem zoo ib yam txawm tias tom qab nws mus txog 40 zaug ntawm kev sim khov-thaw phaum raws-20 ℃. Nws muaj qhov ntxeem tau thiab muaj cov khoom haum. Nws tuaj yeem ua kom kub thiab tiv thaiv kom txhob hws tawm. Dhau li, nws tuaj yeem nqus tau cov duab hluav taws xob hluav taws xob, yog li cov kab ntsig vermiculite tuaj yeem muab tso rau sab hauv chav kuaj los hloov cov laug cam uas kim kom nqus tau txog li 90% ntawm cov duab tawg. 65mm tuab vermiculite yog sib npaug rau 1mm tuab txhuas pawg thawj coj saib.
