*Kusankha ndikusintha chikwama chosefera fumbi

Chikwama chosefera cha chotolera fumbi ndichofunikira kwambiri pazikwama zosefera.Ngati sichinasankhidwe bwino, chimayambitsa kuwonongeka kwa thumba la phala kapena fumbi.

Mukasintha thumba la fumbi, tsegulani chivundikiro chapamwamba cha zida ndikutulutsa khola la thumba, ndiye thumba la fyuluta likhoza kutulutsidwa.Kukonza kosavuta komanso kosavuta.Chikwamacho chimayikidwa m'bokosi la zida, ndipo thupi lachikwama ndilofala kwambiri ngati fyuluta yakunja.Fumbi limasonkhanitsidwa mu chidebe cha wosonkhanitsa fumbi kudzera mu jekeseni wa valve solenoid.Kugwiritsa ntchito muyezo thumba fyuluta thumba.Chosefera chosavuta cha thumba chimayikidwa mu chimango chosavuta.Njira yopangira thumba la fumbi imapangidwa ngati mawonekedwe a fyuluta yamkati, ndipo kupanikizika kwa kunja kwa thumba kumasinthidwa kukhala mawonekedwe amkati.Mwa njira iyi, chipolopolo cha thumba la mtundu wa fumbi wotolera angagwiritsidwe ntchito ngati chimango, popanda kusindikiza kwakunja kwa mbale yachitsulo, yomwe imapulumutsa mtengo ndipo sichilepheretsa kugwiritsa ntchito fumbi.

Kukonza chikwama cha fumbi ndikofunikira kwambiri.M'zaka zaposachedwapa, ena opanga ang'onoang'ono ndi makina ang'onoang'ono kusoka kwa processing zida, ndi otsika mzere pokonza zopangira processing, processing mlingo kutali m'mbuyo.Pangani fumbi thumba mu nthawi yochepa adzayamba kutsegula, kusweka, pansi ndi zochitika zina.Ngakhale kukula kwa thumba ndi kakang'ono kakang'ono, kungagwiritsidwenso ntchito, koma pambuyo pa kuyamwa kwa fumbi lalikulu, thumba la fyuluta lidzagwetsa zochitika za thumba pambuyo pa nthawi yogwiritsira ntchito.

Kuwonjezera pa zomwe zili pamwambazi, makhalidwe a fumbi la fumbi ndilofunikanso chidwi chathu.1, kukana kwamankhwala: mankhwala otsika kwambiri amatha kufananizidwa ndi mankhwala otsika a ulusi wa fluorine.Pa 200 ℃ ndi pansi, ili ndi mankhwala otsika otsika a ma acid ambiri (kupatula ma oxidants monga concentrated nitric acid), maziko ndi zosungunulira organic.2, pambuyo poyaka ndi kugudubuza, phulusa ndi losavuta kuchotsa.3. Thumba lopanda fumbi limakhala ndi kukana kwamadzi kwabwino ngakhale litagwiritsidwa ntchito kwa maola 500 mosalekeza pa 160 ℃ ndi 79% chinyezi wachibale.4, kukana kutentha, malo osungunuka mpaka 285 ℃, ndikuchita kwanthawi yayitali kutsika kwamafuta.Kugwiritsa ntchito mosalekeza pa 190 ℃.5, ngakhale mu 160 ℃ mkulu kuthamanga nthunzi akhoza kusunga 90% ya mphamvu.6, fumbi thumba makina makhalidwe: mphamvu, elongation, elasticity ndi poliyesitala ndi chimodzimodzi.6, kuyaka: ndi kuyaka kwambiri komanso kuyaka modzidzimutsa (LOI imachepetsa mpweya wa oxygen index 34-35).7, kukana kwa radiation: kukana kwa radiation kwa ray ndi mzere wapakatikati ndikotsika, poyerekeza ndi dianlong yachikhalidwe, poliyesitala ili ndi kusintha kwakukulu.8, mawonekedwe amagetsi: kutentha kwambiri, chinyezi chambiri, mikhalidwe yayikulu pafupipafupi, kuwonetsa kosakhazikika kwamagetsi okhazikika.

Komanso, fumbi kuchotsa dzuwa la thumba lomwelo ndi osiyana pansi pa ntchito zosiyanasiyana.Kuchuluka kwa fumbi pamwamba pa thumba fyuluta kudzakhudza mwachindunji fumbi kuchotsa dzuwa la thumba fyuluta.Kuchita bwino kwa fumbi la fumbi mutatha kuyeretsa kumakhala kochepa kwambiri, kuchotsera fumbi kwa fumbi la fumbi kulidi kwakukulu, ndipo mphamvu ya kuchotsa fumbi idzachepetsedwa.Zitha kuwoneka kuti chifukwa chomwe thumba la fumbi limagwira ntchito yochotsa fumbi ndikuti fumbi pamwamba pa thumba la fumbi ndilo kusefera kwachiwiri kwa fumbi.Chifukwa chake, poyeretsa thumba losunga fumbi, tiyenera kusunga fumbi moyenera pathumba la fumbi.Kukula kwa fumbi particles kumakhudzanso fumbi kuchotsa zotsatira za thumba fyuluta.
