Mu ntchito zofunika kwambiri, mainjiniya nthawi zambiri amaphatikiza kukula kwa ma pore ang'onoang'ono ndi mawonekedwe abwino a fyuluta kuti asunge magwiridwe antchito osefera komanso magwiridwe antchito a dongosolo.

2. Kodi kukula kwa ma pore ochepa nthawi zonse kumakhala bwino?

Ayi. Ngakhale kuti kukula kwa machubu ang'onoang'ono kumathandiza kuti tinthu tisungike bwino, kumawonjezeranso kukana kuyenda kwa madzi, zomwe zimapangitsa kuti mphamvu ya mpweya itsike kwambiri komanso kuti pakhale chiopsezo chachikulu chotseka.

Nthawi zambiri, kusankha kukula kwa ma pore ochepa kwambiri kumabweretsa kuchepa kwa magwiridwe antchito a makina komanso ndalama zambiri zokonzera.

Chisankho chabwino kwambiri nthawi zambiri chimakhalakukula kwa pore yolinganizidwazomwe zimakwaniritsa zofunikira zosefera popanda kusokoneza kayendedwe ka madzi ndi moyo wautumiki.

3. Kodi kusiyana pakati pa nominal ndi absolute micron rating ndi kotani?

Kuyeza kwa micron mwachizolowezi kumasonyeza kusefa pang'ono (nthawi zambiri 60–90% kuchotsa tinthu tating'onoting'ono pa kukula kopatsidwa), pomwe kuyerekeza kwathunthu kwa micron kumayimira mphamvu yayikulu yosungira (nthawi zambiri ≥99.9%) pansi pa mikhalidwe yoyesedwa yodziwika.

Kumvetsetsa kusiyana kumeneku n'kofunika kwambiri, chifukwa zosefera ziwiri zomwe zili ndi micron rating yofanana zimatha kugwira ntchito mosiyana kwambiri kutengera momwe zimagwirira ntchito komanso kapangidwe kake.

4. Kodi ndingatani kuti ndisatseke ma fyuluta achitsulo osalala bwino?

Kutsekeka kwa khosi kungachepetsedwe ndi izi:

• Kusankha kukula koyenera kwa pore kutengera kuchuluka kwa tinthu tating'onoting'ono
• Kugwiritsa ntchito pre- magawo osefera kuti achotse tinthu tating'onoting'ono tating'onoting'ono
• Kupanga njira yotsukira kapena kutsuka (monga kutsuka ndi ultrasound)
• Kukonza bwino momwe madzi amayendera kuti achepetse kuchulukana kwa tinthu tating'onoting'ono

M'machitidwe ambiri, kuphatikiza kusankha koyenera kwa kukula kwa ma pore ndi kapangidwe kabwino ka makina kumawonjezera nthawi yogwiritsira ntchito fyuluta.

5. Kodi zosefera zachitsulo zokhala ndi mabowo zingathe kutsukidwa ndikugwiritsidwanso ntchito?

Inde. Chimodzi mwa ubwino waukulu wa zosefera zachitsulo zokhala ndi porous ndikugwiritsidwanso ntchito.

Kutengera ndi momwe zagwiritsidwira ntchito, zimatha kutsukidwa pogwiritsa ntchito:

• Kupukuta kumbuyo
• Kuyeretsa kwa akupanga
• Kuyeretsa mankhwala

Izi zimapangitsa kuti zikhale zoyenera kwambiri pamafakitale komanso ntchito zapamwamba komwe nthawi yayitali yogwirira ntchito komanso kugwiritsa ntchito bwino ndalama ndizofunikira.

6. Kodi ndi kukula kotani kwa ma pore komwe kumagwiritsidwa ntchito mu semiconductor kapena high-purity applications?

Mu ma semiconductor ndi ma ultra-high purity gas systems, ma pore sizes ang'onoang'ono kwambiri—nthawi zambiripansi pa 1 μm— amagwiritsidwa ntchito kuonetsetsa kuti pali kuipitsidwa kotheratu.

Mu ntchito zina zapamwamba, kusefa pang'ono kwambiri kungafunike, kutengera kukhudzidwa kwa njira ndi miyezo ya ukhondo.

7. Kodi ndi liti pamene ndiyenera kuganizira za fyuluta yachitsulo yokhala ndi mabowo apadera?

Mayankho opangidwa mwamakonda ayenera kuganiziridwa pamene:

*Makulidwe a pore wamba sangakwaniritse zofunikira zonse ziwiri zosefera komanso kayendedwe ka madzi
*Dongosololi lili ndi kutsika kwa mphamvu kapena malire a malo
*Kugwiritsa ntchito kumakhudza zinthu zoopsa kwambiri (kutentha, kupanikizika, dzimbiri)
*Kugwira ntchito kosalekeza komanso kobwerezabwereza ndikofunikira kwambiri

Pazochitika izi, kusintha kukula kwa ma pore, kapangidwe kake, zinthu, ndi mawonekedwe ake kungathandize kwambiri magwiridwe antchito a dongosolo lonse.

8. Ndi zipangizo ziti zomwe zili bwino kwambiri pa zosefera zachitsulo zokhala ndi mabowo?

Kusankha zinthu kumadalira malo ogwiritsira ntchito. Zosankha zodziwika bwino ndi izi:

• Chitsulo chosapanga dzimbiri cha 316L → kukana dzimbiri komanso kulimba bwino
• Titaniyamu → yoyenera malo owononga kwambiri kapena malo apadera
• Nickel ndi alloys → zomwe zimagwiritsidwa ntchito m'mafakitale kapena mankhwala enaake

Kusankha zinthu zoyenera kumatsimikizira kudalirika kwa nthawi yayitali komanso kugwirizana ndi momwe zinthu zilili.

Kusankha kukula koyenera kwa poreszosefera zachitsulo zokhala ndi pobowokwenikweni ndi kupanga zisankho zaukadaulo wodziwa bwino ntchito

zomwe zimagwirizana ndi zosowa zenizeni za ntchito. Pamene magwiridwe antchito osefa, kukhazikika kwa dongosolo, ndi mtengo wa nthawi yayitali zonse ndizofunikira, njira yolinganizidwa yosankha kukula kwa ma pore ingapangitse kusiyana kwakukulu.

Pa mapulojekiti ambiri, makamaka omwe amakhudza zofunikira zoyera kwambiri kapena zovuta zogwirira ntchito, kugwira ntchito ndi mnzanu amene amamvetsetsa mfundo zosefera komanso zovuta zenizeni za dongosolo kungachepetse kwambiri kuyesa ndi kulakwitsa ndikufulumizitsa kukhazikitsa.

HENGKOthandizani mainjiniya ndi magulu aukadaulo ndi njira zosefera zomwe zimagwiritsidwa ntchito ndi mapulogalamu

—kuyambira kusankha kukula kwa ming'alu mpaka kusintha kwathunthu kwa zigawo zachitsulo zokhala ndi ming'alu.

Mwa kuphatikiza kuwongolera kolondola kwa kapangidwe ka ma pore ndi kapangidwe kosinthasintha komanso zosankha zazinthu,

Timathandiza kuonetsetsa kuti yankho lililonse likugwirizana ndi zosowa za dongosololi.
