Kodi zinthu zazikulu ndi makhalidwe a chophimba cha polyurethane ndi ziti?

Ma screen a polyurethane omwe amagwiritsidwa ntchito nthawi zambiri amakhala ndi ma screen a polyurethane mine ndi ma screen a polyurethane dehydration. Ma plate a polyurethane screen amagwiritsidwa ntchito mu metallurgy (chitsulo, miyala yamwala, fluorite, cooling blast furnace slag, coke ndi zipangizo zina zopangira), zitsulo zopanda ferrous, malasha, mankhwala, zipangizo zomangira ndi hydropower engineering, abrasive waste treatment, quarry ndi mafakitale ena. Migodi, kufufuza, kuyika ma grading ndi mafakitale ena.
Magwiridwe antchito ndi makhalidwe akuluakulu a mbale ya sieve ya polyurethane ndi awa:
1. Kukana kwabwino kwa kukanda, kukana kwake kukanda ndi kowirikiza katatu mpaka kasanu kuposa mbale zachitsulo zotchingira ndi kuwirikiza kasanu kuposa mbale wamba zotchingira mphira.
2. Ntchito yokonza ndi yochepa, sikirini ya polyurethane siiwonongeka mosavuta, ndipo nthawi yogwira ntchito ndi yayitali, kotero imatha kuchepetsa kwambiri kuchuluka kwa kukonza ndi kutayika kwa kukonza.
3. Mtengo wonse ndi wotsika. Ngakhale kuti chophimba cha polyurethane cha kukula komweko (dera) ndi chapamwamba kamodzi kuposa chophimba chachitsulo chosapanga dzimbiri (pafupifupi kawiri), nthawi ya moyo wa chophimba cha polyurethane ndi nthawi 3 mpaka 5 kuposa chophimba chachitsulo chosapanga dzimbiri, ndipo chiwerengero cha kukonza ndi kusintha kwake. Chifukwa chake mtengo wonse si wokwera, ndipo ndi wotsika mtengo kwambiri.
4. Kukana chinyezi bwino, kumatha kugwira ntchito ngati madzi ngati njira yolumikizira, ndipo ngati madzi, mafuta ndi zinthu zina, mphamvu ya kukangana pakati pa polyurethane ndi zinthuzo imachepa, zomwe zimathandiza kwambiri kuti zilowe m'malo mwa zotchingira, zimapangitsa kuti ntchito yowunikira igwire bwino ntchito, komanso kupewa tinthu tonyowa. Nthawi yomweyo, chifukwa cha kuchepa kwa mphamvu ya kukangana, kutopa kumachepa ndipo moyo wautumiki umawonjezeka.
5. Yosagwira dzimbiri komanso yosayaka.
6. Chifukwa cha kapangidwe koyenera ka mabowo a sefa ndi njira yapadera yopangira mbale ya sefa, tinthu tating'onoting'ono kwambiri sitidzatseka mabowo a sefa.
7. Kugwira bwino ntchito kwa kugwedezeka, mphamvu yochepetsera phokoso, kumachepetsa phokoso, komanso kupangitsa kuti chophimba chisamasweke mosavuta panthawi ya kugwedezeka.
8. Chifukwa cha kugwedezeka kwachiwiri kwa polyurethane, chophimba cha polyurethane chimadziyeretsa chokha, kotero magwiridwe antchito a chophimbacho ndi apamwamba.
9. Kusunga mphamvu ndi kuchepetsa kugwiritsa ntchito. Polyurethane ili ndi mphamvu yokoka pang'ono ndipo ndi yopepuka kwambiri kuposa zotchingira zachitsulo zofanana, motero imachepetsa katundu wa makina otchingira, kusunga mphamvu ndi kukulitsa moyo wa makina otchingira.
