Tlas'a mokhoa oa ho sebelisa matla a moea a maholo le a lebopong la leoatle, botsitso, matla le ho ikamahanya le maemo hathepa e kopanengSistimi e khetholla ka ho toba bophelo ba lehare le katleho ea tlhahiso ea motlakase. Jwalo ka substrate ea bohlokoa ea ho matlafatsa khetla ea lehare, webo, moeli o etellang pele, moeli o latelang le likarolo tse ling, khalase ea fiber e khaotsoeng e fetohile thepa e tloaelehileng bakeng sa phallo ea vacuum ea VARTM, peista/ho bopa ka letsoho ka ho lekana ho hotle, ho kenella ka potlako, ho bōptjoa ho babatsehang, le ho tlamahana ho matla ha mekhahlelo e fapaneng. Ho khetha mohlala le boima bo fosahetseng, bobebe bo tla lebisa likoli tsa bokaholimo le khaello ea sekhomaretsi phallong, 'me boima bo tla ama matla a sebopeho le ts'ebetso ea mokhathala. Pampiri ena e kopanya mohlala o tloaelehileng ka mokhoa o hlophisehileng, litlhaloso tsa mantlha, mokhoa oa khetho, le ho bapisa ts'ebeliso ea felt e khaotsoeng bakeng sa mahare a matla a moea.

1. Felt e khaotsoeng bakeng sa mahare a motlakase oa moea: litlhoko tsa motheo tsa ho beha le tsa mantlha

-Phapang ea boleng ka sebaka sa yuniti: ± 5%

-Bongata ba mongobo: ≤0.2%

-Matla a ho tenyetseha: ≥30–180N/5cm (eketseha ka boima ba gram)

-Ho kolobisa moea: ho kolobisa ka potlako, lipululana tsa moea o tlase, li loketse ho ntša metsi ka vacuum

-Khanyetso ea boemo ba leholimo/khanyetso ea ho fafatsa letsoai: mehlala ea leoatleng e hloka ho matlafatsa ho ikamahanya le maemo khahlanong le ho bola

-Botsitso: ha ho tahlehelo ea phofo, ha ho na ho beoa ha mealo, ha ho masiba a moriri, a loketse ho beoa ha mealo ka boiketsetso

Felt e khaotsoeng ea khalasehaholo-holo e nka mesebetsi ea ho matlafatsa li-bearing tse seng tsa mantlha, ho homogenization ea bokaholimo, phetoho ea mekhahlelo e fapaneng, le ho hanyetsa ho fetoha ha lehare. E sebelisoa hammoho le lesela le lebang ka lehlakoreng le le leng, lesela le nang le axial e ngata, felt e tsoelang pele, le felt ea bokaholimo ho etsa lera le felletseng la sebopeho.

2. Lethathamo la mehlala le litlhaloso tsa lehare la matla a moea le khaotsoeng

Mefuta e meholo indastering ke EMC (emulsion)/CMC (phofo), 'me bophara bo atisa ho sebelisoa 1250/1040/2500mm. Tse latelang ke mehlala e sebelisoang haholo bakeng sa tlhahiso ea lehare ka bongata.

1) Mohlala o tloaelehileng o tsamaellana le boima ba gram

-EMC225: 225g/㎡, lera le lesesaane la phetoho, bokaholimo bo bonolo

-EMC300: 300g/㎡, matla a maholo a bokahohleng, khetla/web ya bokahohleng

-EMC450: 450g/㎡, matlafatso ea botenya bo mahareng, ho matlafatsa sebaka sa matla

-EMC600: 600g/㎡, matlafatso e teteaneng, ho tenya ha motso/moeli o etellang pele

-EMC900: 900g/㎡, matlafatso a boima, matlafatso ea libaka tsa mahare a maholo

2) Khetho ea mofuta oa binder

-Emulsion type EMC: matla a phahameng, ho tšoana hantle, ho lumellana ho hoholo ha resin, khetho ea pele bakeng sa phallo ea vacuum

-Mofuta oa phofo oa CMC: ho inela ka potlako, litšenyehelo li betere, ho loketse mokhoa oa ho peista ka letsoho/oa thuso

-Matla a moea a kantle ho naha, mahare a matla a phahameng: letoto la pele la emulsion ea EMC

3) Bophara le ho bapisa tshebetso

-1250mm/1040mm: makhapetla a mahareng le a manyane, ho beoa ka letsoho

- 2500mm ho ea holimo: makhapetla a maholo, ho kenya ka bohona, ho fokotsa lekhalo

3. Khetho ka karolo: u ka bapisa libaka tse fapaneng tsa mahare joang?

1) Karolo e ka ntle ea khetla/lera le ka tlase la seaparo sa gel

-E khothaletsoa: EMC225 / EMC300

-Lintlha tsa bohlokoa: bokaholimo bo boreleli, fokotsa masoba a pin, ntlafatsa ponahalo le ho hanyetsa boemo ba leholimo

2) Lera le ka sehloohong la khetla (phetoho/lera la tekano)

-E khothaletsoa: EMC300

-Lintlha tsa bohlokoa: ho leka-lekana ha matla le ho kenella, ho tsamaisana hantle le lesela le nang le axial e ngata

3) Matlafatso ea mahlakore a tepo le sekoahelo sa mahlakore

-E khothaletsoa: EMC450

-Lintlha tsa bohlokoa: ho thatafala ho hoholo, ho hanyetsa ho beola, le botsitso bo ntlafetseng ba sebopeho

4) Moeli o ka pele, moeli o ka morao, sebaka sa ho teteana ha metso

-E khothaletsoa: EMC600 / EMC900

-Lintlha tsa bohlokoa: ho thehoa ka potlako ha likarolo tse teteaneng, ho fokotsa palo ea likarolo, le ho ntlafatsa khanyetso ea tšusumetso

5) Mahare a matla a moea a tsoang mose ho maoatle (spray ea letsoai/mongobo o phahameng)

-E kgothaletswa: masiba a moriri o tlase EMC300/450 + setlolo se kolobisang metsi se hanelang hydrolysis

-Lintlha tsa bohlokoa: ntlafatsa ho hanyetsa botsofali le ho fokotsa kotsi ea ho arohana ha lihlopha
