Fyuluta ya Makandulo Yogwiritsidwa Ntchito mu Pulojekiti Yochotsa Zinthu Zolimba Zoyimitsidwa Pamadzi Otayidwa ndi Mankhwala ku Southeast Asia

Mbiri ya Pulojekiti
Kampani yopanga mankhwala yomwe ili ku Southeast Asia, makamaka yopanga zinthu zothandizira mafakitale ndi ma surfactants, imapanga madzi ambiri otayira okhala ndi tinthu tomwe timapachikidwa. Zipangizo zoyambirira zosefera zinali makina osefera a mbale ndi chimango, zomwe zinali ndi mavuto monga kutulutsa madzi m'manja pafupipafupi, ndalama zambiri zosinthira nsalu zosefera, komanso malo ambiri osungiramo zinthu. Kasitomala adafuna chipangizo chodziyimira chokha, chotsika mtengo cholekanitsa madzi olimba chomwe chimatha ntchito bwino chomwe chimasefera molondola ma microns 5 komanso mphamvu yochizira matani 20 a madzi otayira patsiku.

Yankho
Tinasintha zinthu kukhalaFyuluta ya makandulo ya JYCFS-17M2kwa kasitomala. Chipinda ichi chili ndi malo osefera a 17 m², chipolopolo cha chitsulo cha kaboni, ndi makandulo 38 a SS304 osapanga dzimbiri (1,750 mm m'litali) okhala ndi nsalu yosefera ya polyester. Chimakwaniritsa kulondola kosefera kwa ma microns 5. Kupanikizika kwa kapangidwe kake ndi mipiringidzo 6, kuthamanga kwa ntchito ndi mipiringidzo 4, kutentha kwa kapangidwe kake ndi 150°C, ndipo kutentha kwenikweni kwa ntchito kumakhala pakati pa 85°C ndi 90°C. Chisindikizo chophimbacho chimagwiritsa ntchito fluororubber (FKM), ndipo pansi pake pali valavu yodziyimira yokha ya pneumatic blowdown. Dongosolo lonseli limaphatikizapo chimango chothandizira chitsulo cha kaboni.

Ubwino waukulu wa yankho ili ndi:

• Kugwira ntchito kokhazikika, kuchotsa kulowererapo kwamanja pafupipafupi.

• Kutsuka bwino kumbuyo ndi kutulutsa keke yokha chifukwa cha kapangidwe ka fyuluta ya makandulo.

• Kutulutsa kwa slag komwe kumachitika zokha kudzera mu valavu yotsika pansi ya pneumatic blowdown, kumachepetsa kwambiri ntchito yamanja.

Zotsatira za Ntchito
Pambuyo pa miyezi itatu yogwira ntchito mosalekeza, ndemanga za makasitomala zimaphatikizapo:

• Kusefa: Zinthu zolimba zomwe zinapachikidwa mumadzi otayira madzi zinkayang'aniridwa nthawi zonse pansi pa ma microns 5, zomwe zinakwaniritsa zofunikira za kasitomala kuti madzi abwererenso pamene ankapangidwa. Makandulo osefa sanatseke kapena kusintha. Kutsuka ndi kukonzanso zinthu kumbuyo kunali kothandiza, ndipo kuphatikiza nsalu yosefa ya polyester ndi makandulo a SS304 kunasonyeza kulimba kwabwino.

• Makina Odzichitira: Valavu yoyatsira mpweya pansi pa mpweya imatulutsa yokha slag motsatira ndondomeko yokhazikitsidwa. Njira yonse yosefera ndi kutulutsa slag sinafunikire kugwira ntchito ndi manja, zomwe zimachepetsa kwambiri ntchito ya ogwira ntchito pamalopo. Poyerekeza ndi makina osindikizira a fyuluta omwe anali kale, pafupifupi maola awiri otulutsa slag anasungidwa patsiku.

• Mtengo wogwiritsira ntchito: Chipolopolo cha chitsulo cha kaboni (kukhuthala kwa 6 mm) chinasonyeza kapangidwe kolimba popanda kutayikira. Chisindikizo cha FKM chinagwira ntchito bwino pa 85–90°C, sichinasonyeze zizindikiro zakukalamba kapena kulephera. Pambuyo pa miyezi itatu yogwiritsidwa ntchito, makandulo ndi nsalu zosefera zinakhalabe bwino, ndipo nthawi yosinthira ikuyembekezeka kukwaniritsa zomwe zimayembekezeredwa pakupanga.

Ndemanga za Makasitomala
Woyang'anira ntchito yokonza makasitomala anati fyuluta ya makandulo iyi yathetsa vuto lochotsa zinthu zolimba zomwe zapachikidwa m'madzi otayira. Ntchito yozimitsa yokha yapangitsa kuti ntchito pamalopo ikhale yosavuta komanso yodalirika. Zipangizozi zimagwira ntchito bwino popanda kufunikira kokonza kwambiri, ndipo chitsanzo chomwecho chidzayikidwa patsogolo pa ntchito zowonjezera zamtsogolo.

Chidule cha Nkhani
Nkhaniyi ikusonyeza kuti fyuluta ya makandulo ya JYCFS-17M2 ndi yoyenera kuchotsa zinthu zolimba zomwe zimapachikidwa m'madzi otayira mankhwala. Kuphatikiza kwa chitsulo cha kaboni ndi chitsulo chosapanga dzimbiri kumalimbitsa kukana dzimbiri komanso kugwiritsa ntchito bwino ndalama. Ntchito zotsuka zokha komanso zopumira mpweya ndi zabwino kwambiri m'mafakitale omwe amafunika kuchepetsedwa. Kulondola kwa kusefa kwa ma micron 5 kumakwaniritsa zofunikira za kuyeretsa madzi ambiri m'mafakitale komanso kulekanitsa madzi olimba.
