E rehiloe lebitso la eDNA bakeng sa Lithuto tsa Tikoloho ea Lefatše (eDGES), merero e kenyelletsa lipatlisiso tsa ho ntlafatsa ho lekola Pilbara Olive Python e kotsing ea ho fela / e sa tloaelehang le libaka tse mongobo tse phahameng tsa bohlokoa tsa machabeng naheng ea Chile le ho nts'etsapele liteko tse ncha tsa ho bona mefuta e hlaselang ea leoatle e amanang le ho koaloa ha meaho. tikolohong ya lewatle. 

"Bafuputsi ba rona ba se ba ntse ba sebetsa ho fumana tharollo ea mathata a rona a lefats'e la sebele," motlatsi-mokhansele oa Univesithi ea Curtin, Deborah Terry, o boletse ka bokhutšoanyane.

"Litsebi tsa rona tsa saense, boenjiniere le saense ea data li ka pele ho thepa e ncha, mekhoa e mecha ea tlhahiso le bohlale ba maiketsetso. Ke boitseanape bona, menahano e ncha le ponelopele ea bokamoso ba Curtin e tla tlisa selekane sa rona le BHP. "

Lithane tse 13 tsa Jaw Plate Production Processing

Selemong sa 2008, H&G Machinery e ile ea fumana taelo ho tsoa ho moreki oa USA, ea hlokang ho hlahisa lesela le leholo la ho silakanya mohlahare. Boima bo pota-potileng lithane tse 13, boholo: 4200mm * 2300mm * 400mm, sefahleho sa leino se sebetsa sefahlehong, sefahleho se ka morao ke sefahleho sa ho kenya, ho hloka machining, thepa e ne e khethile Mn18 alloy steel.

E le ho fumana khanyetso e ntle ea Wear, re hloka ho kenyelletsa "Ni" le "Mo" likarolo.

Tlhahiso ea Tlhahiso

1. Re khetha lehong ho etsa mohlala o moholo oa poleiti ea mohlahare.
2. Lehlabathe le bōptjoang ke lehlabathe la sodium silicate chrome ore sand, 'me lehlabathe la bobeli ke lehlabathe la sodium silicate limestone, le khonang ho honyela ka mor'a ho tšela.
3. Phaephe ea litene e phahameng ea alumina e sebelisoa tsamaisong ea liheke ho etsa bonnete ba hore tšepe e qhibilihisitsoeng ha e kopane le lehlabathe le bopehang ho semathi, e le ho fokotsa ho hlatsoa lehlabathe, lesoba la lehlabathe, lesoba la moea le liphoso tse ling; Mahlakore a 12 a ajoang ka ho lekana a sebelisoa bakeng sa semathi se ka hare; Li-roses tse 4 tse futhumatsang li hlophisitsoe ka lehlakoreng la poleiti e nang le meno e shebaneng le semathi sa ka hare; hlobo ea lehlabathe e kenngoe ka 20cm holimo lehlakoreng la risepe ho nolofatsa mosi le ho ntlafatsa phello ea phepelo ea molomo oa mollo; phofo ea zircon e entsoeng ka joala e sebelisoa e le ho roala Pente, borashe likarolo tsa 2, ho chesa le ho chesa ka nako ka mor'a ho penta ka 'ngoe; hlahloba 'me u netefatse ka hloko pele u koala lebokose,' me u tiise ka ho lekana ka liboutu ka mor'a ho koala lebokose.

Ho qhibidiha le ho tshela

1.  Litšepe tsa boleng bo phahameng tse batang tse se nang oli le mafome li khethoa bakeng sa sekhechana. Li-alloys tsohle li lekoa pele. Ke lisebelisoa tsa boleng bo phahameng feela tse nang le sebopeho se hlakileng se ka kenngoa ka sebōping.
2. Bokaholimo ba ts'ebetso ea ho qhibilihisa bo koahetsoe ka lejoe la mokoetla ho fokotsa oxidation le moea oa tšepe e qhibilihisitsoeng. Sampole ea tšepe e qhibilihisitsoeng pele ho sebōpi e ka ntšoa ka mor'a ho fetisa tlhahlobo ea spectrum le tekanyo ea mocheso.
3. Nakong ea ho tlanya, silicon ea lefatše e sa tloaelehang e ile ea fetoloa ka mokhoa oa ho hlatsoa ladle ho ntlafatsa boholo ba lijo-thollo.
4. Argon e fefoloa ka har'a ladle ho tlosa litšila le likhase. Ha argon e phunyeletsoa ka har'a ladle, mocheso o lokela ho lekanyetsoa ho etsa bonnete ba hore mocheso oa ho tšela o kopana le litlhoko tsa ts'ebetso.
5. Mocheso oa ho tšollela o laoloa ho 1410-1425 ℃ 'me ho lahla ho hoholo hoa ho amoheloa.
6. Ka mor'a ho tšela, koahela riser ka sehlaseli se chesang ho netefatsa phepo e nepahetseng.

Insulation le ho Hloekisa

1. Ka mor'a ho tšela, lehlabathe le motso oa riser le lokela ho sisinyeha ka nako ho qoba ho fokotseha le ho phatloha ha ho lahla;

2. Ka mor'a ho phutholla, riser e lokela ho koaheloa ka lehlabathe le omeletseng 'me e pholile butle-butle;

3. Ha u khaola riser, e khaole ka potlako 'me u koahele sehiloeng ka lehlabathe le omeletseng ebe u se pholile mocheso oa kamore

Kalafo ea Mocheso

Phekolo ea mocheso e amohela ho tima metsi a pholileng. Mokhoa oa ho phekola mocheso o bontšoa setšoantšong se ka tlase:
