Mtengo wa 2021 White Perlite - Perlite yogulitsa kwambiri kapena perlite yaulimi kapena perlite yowonjezera yogwiritsidwa ntchito m'munda - Kehui

Perlite yowonjezera ndi mtundu wa zinthu zoyera zokhala ndi kapangidwe ka uchi mkati mwake zomwe zimapangidwa ndi miyala ya perlite pambuyo potenthedwa kale komanso kuwotcha ndi kukulitsa kutentha kwachangu. Mfundo yaikulu ndi yakuti: miyala ya perlite imaphwanyidwa kuti ipange mchenga wa tinthu tating'onoting'ono tating'onoting'ono, womwe umatenthedwa bwino ndikuwotchedwa ndikutenthedwa mwachangu (kupitirira 1000 ℃). Madzi omwe ali mu miyalayi amasanduka nthunzi ndikufalikira mkati mwa miyala yofewa ya vitreous kuti apange mchere wosakhala wachitsulo wokhala ndi kapangidwe ka mapokoso ndi kukula kwa voliyumu ka 10-30. Perlite imagawidwa m'mitundu itatu malinga ndi ukadaulo wake wokulitsa ndi kagwiritsidwe ntchito: mapokoso otseguka, mapokoso otsekedwa, ndi mapokoso opanda kanthu.

Kukula kwa Tinthu

1-3mm, 3-6mm, 4-8mm.

Kukula kwa ntchito

Perlite yowonjezeredwa ndi mchere wosapangidwa ndi zinthu zachilengedwe womwe umagwiritsidwa ntchito mosiyanasiyana. Malinga ndi ukadaulo wake wokulitsa ndi ntchito zake, umagawidwa m'mitundu itatu: ma pores otseguka, ma pores otsekedwa, ndi ma pores opanda kanthu. Zogulitsazo zimakhudza pafupifupi minda yonse. Mwachitsanzo:

1- Chopangira mpweya, chosungiramo zinthu zozizira, mpweya wamadzimadzi ndi mayendedwe a nayitrogeni wamadzimadzi ngati zinthu zodzaza zotetezera kutentha.

2- Amagwiritsidwa ntchito posefa mowa, mafuta, mankhwala, chakudya, zimbudzi ndi zinthu zina.

3- Za rabala, utoto, zokutira, mapulasitiki, ndi zina zotero.

4- Za zolimbikitsa kukhudzidwa.

5- Amagwiritsidwa ntchito poyamwa mafuta otayirira.

6- Amagwiritsidwa ntchito mu ulimi, ulimi, kukonza nthaka, kusunga madzi ndi feteleza, kulima popanda dothi, kukonza nthaka, mankhwala ochepetsa tizilombo, ndi zina zotero.

7- Imagwiritsidwa ntchito pogwirizana ndi zomatira zosiyanasiyana popanga ma profiles okhala ndi ma specifications ndi makhalidwe osiyanasiyana.

8- Kuchuluka kwakukulu kumagwiritsidwa ntchito poteteza kutentha kwa ma uvuni a mafakitale ndi madenga ndi makoma a nyumba. Malo omanga: kuteteza kutentha, zokutira zoletsa moto, mapanelo olandirira mawu ndi zina zotetezera kutentha kwa mapaipi, kuteteza kuzizira ndi kutentha, zipangizo zosefera, zipangizo zosonkhanitsira slag popanga zitsulo, zipangizo zodzaza mphira ndi pulasitiki, ndi zina zotero.
