Choncho, mchere zachilengedwezi ali katundu zotsatirazi:

• chilengedwe waubwenzi;
• durability;
• mankhwala ndi inertness kwachilengedwenso anakumana ndi atolankhani aukali;
• otsika matenthedwe madutsidwe;
• mkulu moto kukana;
• otsika kachulukidwe.

Komanso, ndi ncho ku Australia, India, South Africa, Uganda ndi United States. Mu Montana, pafupi ndi tauni ya Libby, ili lalikulu ndi kopindulitsa kwambiri US gawo la mchere ndi.

Kodi processing

Zotsatira vermiculite pansi pa chithandizo chapadera kwa concentrators lapansi. Pali kuchititsa Kusankha ndi kusanja Mica, ena amene kenako imatumizidwa yopanga magetsi, ndi otsala a kukonzedwa mu Madziwo njira conveyor ng'anjo pa kutentha pafupifupi 760 ° ^C. Chifukwa cha kukhudzana iyi particles munthu pathupi ndi delaminate mchere, ndipo linanena bungwe ndi kukodzedwa vermiculite. Pa zina processing misa kupeza n'kukhala mtengo anakonzeratu.

Features kukodzedwa vermiculite

Monga tanenera kale, mchere zachilengedwezi processing mafakitale kumachitika kuwombera, umene kwambiri kuchuluka M'BUKU, ndipo stratified mu particles nyongolotsi-ngati. kusintha Ichi ndi chifukwa madzi amene ali mu dongosolo la vermiculite mu mkhalidwe adzamangidwa. Mchikakamizo cha kutentha ndi usavutike ndipo anatembenukira kwa nthunzi, lomwe lakamba zambiri ndi mbale stratifies Mica, potero kuwonjezeka voliyumu. Choncho, tingathe kulankhula za vermiculite kukodzedwa kuti ndi "anaumitsa" mchere restructured.

Kodi tuzigawo twa?

Yothandiza pulverized malasha tizigawo osiyana omwe ali m'magulu malinga ndi kukula. Okwana pali magulu 5, pomwe 1 ndi kukula yaikulu ya ndalama yachitsulo yaing'ono, ndi 5 - slurry chokhala fumbi kapena mchenga chabwino. Unmilled vermiculite - kutentha kutchinjiriza chuma, ankagwiritsa ntchito yomanga kwa kudzazidwa mu gulu dzenje.

Mu horticulture ndi chomera vermiculite amangoona ntchito pa 2 mpaka 4 ting'onoting'ono. Nkhanizi mu mawonekedwe youma m'malo zosavuta, koma pambuyo hydration zayamba kumawonjezera ake nthawi kulemera 5, chifukwa madzi odzipereka ndipo anapitiriza.

Minda ya ntchito

Tsegulani posachedwapa, ndi mchere, vermiculite, ndi ena ofanana tsopano anapeza ntchito zosiyanasiyana:

1. Ubale, mafuta ndi mankhwala Makampani. anthu ochepa akhoza kuyankha pamene anafunsidwa za vermiculite, amene ndi sorbent kwambiri angathe kumanga soda ndi acid. katundu Zimenezi zimathandiza kuti n'chongoletsa zosiyanasiyana zinthu mankhwala kuntchito, komanso kuchepetsa mumapezeka mafuta.
2. Makampani nyukiliya ndi mphamvu. Izo ntchito monga mkangaziwisi wa zinthu nyukiliya monga cobalt 58, strontium-90, cesium 137, komanso ngati gamma-cheza imaonetsa.
3. Magalimoto ndi ndege makampani. Anapanga zosiyanasiyana phokoso-kungolandira vermiculite ndi zipangizo matenthedwe kutchinjiriza ndi mankhwala.
4. Mu mafakitale ndi yapachiweniweni vermiculite kumanga ntchito motere:

• kutchinjiriza, komanso kulira ndi kutentha insulator kwa madenga ndi simenti;

• backfiller ngati kutchinjiriza nkhani za gulu dzenje;
• ndi mbali ya pulasitala zosiyanasiyana, opepuka simenti ndi nyumba youma kasakaniza;
• mu kupanga simenti ndi midadada konkire, ndiponso chimateteza utomoni wonunkhira monga filler ndi;
• kupanga moto wamtundu uliwonse ndi kutentha zosagwira mbale, mapanelo ndi zipangizo zina pakhoma;
• ndi kusinthika kwa moyo wodzikonda kukhazikika mbewu.

5. Mu mafakitale ndi ena kuswana zomera ndi horticulture. Tiyeni tione mwatsatanetsatane mmene ntchito vermiculite mbewu.

Features ntchito mu mbewu

mchere izi, zapitazi processing mafakitale, ankagwiritsa ntchito mbali iliyonse ya zomera zikule ndi chitukuko:

• pa mbewu kumera ndi cuttings rooting omwe si anakhudzidwa ndi tizilombo zosiyanasiyana - tizilombo toyambitsa matenda ndi nkhungu, komanso kupeza zakudya zonse zofunikira ndi mme- zinthu;
• kulenga zosakaniza zosiyanasiyana nthaka ndi atipatse friability anakhumba ndi porosity;
• pamene kulimapo hydroponic;
• ngati ngalande wosanjikiza zosiyanasiyana mbewu monga mphika, ndi zomera munda;
• Kuphimbira kubzala;
• chifukwa yosungirako chisanu ndi klubnelukovichnyh mbewu zosiyanasiyana bulbous: vermiculite osati kuthandiza yachibadwa kutentha ndi mpweya zinthu, komanso kumathandiza imfa ya chuma kubzala ndi matenda osiyanasiyana ndi tizilombo toyambitsa matenda;
• mu ndondomeko ya kulenga manyowa.

Ponena za vermiculite - chimene icho chiri, chifukwa tikuzifuna, ayenera kukumbutsidwa malamulo zingapo zosavuta kuti ayenera kutsata pamene akugwira ntchito ndi iwo:

1. Ntchito chuma angagwiritsidwe ntchito, koma pokhapokha calcination kuvomerezedwa.
2. Popeza zimatenga madzi ambiri kwa nthawi yaitali ndipo akuupereka kwa zomera, tiyenera kukumbukira, ndi kupewa kuthirira kwambiri tingayambe waterlogging wa nthaka ndi zomera imfa.
3. Awiri mchere zinthu - perlite, vermiculite - ndi katundu zofanana, iwo akhoza kugwiritsidwa ntchito pamodzi ndi kukula kwa zomera.
4. Nkofunika kukumbukira kuti vermiculite interacts ndi madzi zovuta ndipo akhoza "kusuntha" acidity wa nthaka mbali zamchere. Ndicho chifukwa Akatswiri ambiri kulengeza ntchito vermiculite wangwiro kokha kwa germinating mbande kapena pamene akugwira mbewu hydroponics pamene zikuchokera khalidwe madzi amadziwika ndi zonse.
