Yog li, qhov no tej yam ntuj tso mineral muaj cov nram qab zog:

• tej friendliness;
• durability;
• tshuaj lom neeg thiab lom inertness nyob rau hauv kev sib cuag nrog txhoj puab heev xov xwm;
• tsawg thermal conductivity;
• siab tua hluav taws kuj;
• tsawg ceev.

Qhov uas nws yog mined?

Qhov no tej yam ntuj tso khoom tau pheej nrhiav tau nyob rau hauv lub XIX caug xyoo, thiab txij thaum ntawd los nqa tawm nws kev tshawb kawm thiab ntau lawm.

Qhov kev hloov no yog vim cov dej uas yog nyob rau hauv cov qauv ntawm cov vermiculite nyob rau hauv ib tug bound lub xeev. Nyob rau hauv tus ntawm siab kub nws yog rhuab thiab hloov dua siab tshiab rau zog, uas nthuav thiab, stratifies mica phaj, li no ua lub ntim. Yog li, peb yuav tham txog lub txhab vermiculite uas yog "tawv" mineral restructured.

Yuav ua li cas yog me?

Pab yog pulverized cov pob txha rau ntau cov zauv feem uas yog txwv kom muab zais raws li loj.

• raws li ib feem ntawm ntau yam plaster, khaub-ncaws nyias qhob thiab qhuav lub tsev hmoov sib tov;
• nyob rau hauv qhov siv thiab ua MAAs thiab pob zeb ua blocks, thiab insulating mastic raws li ib tug tub lim;
• nyob rau hauv zus tau tej cov hluav taws-retardant thiab tshav kub-resistant phiaj, panels thiab lwm yam phab ntsa ntaub ntawv;
• lub lwm ntawm tus kheej-leveling plag tsev.

5. Nyob rau hauv lub industrial thiab lwm tsob nroj yug me nyuam thiab horticulture. Cia peb xav txog nyob rau hauv ntau yam yuav ua li cas siv vermiculite nroj tsuag.

Nta ntawm kev siv rau tsob nroj

Qhov no mineral, yav tas los tus muaj ua, dav siv nyob rau hauv tag nrho cov theem ntawm tsob nroj kev loj hlob thiab kev loj hlob:

• thaum lub sij hawm noob germination thiab rooting cuttings, uas yog tsis cuam tshuam los ntawm ntau yam kab mob - pathogens thiab fungi, raws li zoo raws li tau tag nrho cov tsim nyog cov as-ham thiab lw ntsiab;
• los mus tsim ntau yam av mixtures thiab impart cov yam friability thiab porosity;
• thaum loj hlob hydroponic cov qoob loo;
• raws li ib tug kua txheej nyob rau hauv ib tug ntau yam ntawm cov qoob loo raws li ib lub lauj kaub, thiab vaj nroj tsuag;
• Mulch cog;
• rau lub caij ntuj no cia thiab klubnelukovichnyh ntau yam bulbous cov qoob loo: vermiculite tsis tsuas txhawb lub cev kub thiab roj tej yam kev mob, tab sis kuj tsis pub poob ntawm cog cov ntaub ntawv uas nrog ntau yam kab mob thiab pathogens;
• nyob rau hauv tus txheej txheem ntawm kev tsim nplooj lwg.
