Kuminingo, amapheshe ya polyurethane enza amapheshe aqalela ngempumelelo ngokuhambelana nezinye ezindzabukayo zokwezwa zemali. Imbono yesipho ibonisa ukuthi le mapheshe kahle kakhulu iyadinga ukuthi ifakwe kabusha ngoba iyadinga amamininingo angu-3 ku-8 okulinganisa nezinye. Okwenza i-polyurethane ngokwehlisa ngokuthi yisipho esikhulu kakhulu. Ukunciphisa ukuguqula amapheshe kwenza ukuthi ikhono lasebenza ngokuhle ngenxa yokuthi kungena amamininingo angafanele. Kumaqo aphindaphindwa ngokuphelele, lokhu kuyindlela yokuthi amamininingo ayidalwa ngenxa yokuthi amamininingo awukelwa. Abanye amakhampani abonisa ukuthi bathola amapheshe eziyona ngokuthi aqale ukusebenzisa lezi zimpawu zokwenzeka futhi bathole ukuthi ikhono lasebenze ngokuphelele.
Ngokukhetha imishini yesikrinyi, izinkampani zingathola ukunciphisa okuphakathi kwezindleko zokulungiswa ngenani eliphezulu kulesithupa, ngokwesicatshulwa saseMakete, okubonisa izintela zazo ezinhle. Lokhu kudingekile kakhulu eminingeni ngaphandle kwezimo ezifanele ukuthi izikhathi ezingenakusebenza zingathathwa ngokuphelelwe.
Indlela ebalulekile yokuba yisikulu senkcazo ye-polyurethane kukhona indlela enempisweni yayo, ngakumbi kakhulu kuzo zindawo zokumineka ezinemvula apho izikulu zezinhloko zokuxhasama kahle. Izivivinyo zokusebenza kubonisa ukuthi leli nqanaba lasebenza ngempela ngokulawulwa kwekhaba xa kuzozokudlala, lokhu kusho ukuthi kudinga kude kakhulu futhi kuvikela ukusebenza ngendlela elula. Kumaqo athintekayo ukuba abeke amagugu ngokuphelele ngaphandle kokuthintana ngokuphelele izikulu, le ndlela yokuba yinkcazo iyahlulela konke. Noma lapho kuthiwa kakhulu kuzindlela ezilungile, izikulu ze-polyurethane zikhale nezifiso, ukuvikela amaqo ukuba avikele amathimele athinta ukukhululwa ngokweqile.
Kubekwa ngekuphuthumayo kwezintambo zokuhlola, izintambo zepolyurethane ziphumelela kuzindlela zokusebenza ngokuthula futhi kuzindlela eziphakeme kakhulu, zibonisa indima yabo esimweni yokuthula nokuthula, ngakho akhuthaza ukusebenza ngokuhle futhi ukuncipiswa kwamathime.
Imiproperties yokuqina ngokusebenzisa i-polyurethane iyahlukisa konke xa kufanele kwahlukiswe amagugu, ngokukodwa kuba yabo bangelisa indlela le-vibrations ehlukana ngayo kwiingxenye kwaye iyakunceda ukuvuleka ngokusebenzisa izicathami. Iindlela zombono zibonisa ukuba le ndlela yokuhlukahluka kuyakunceda abasebenzisi ukutshintsha ngokweminye yokuqina kunye nokukhawuleza kwe-vibrations, oko kuyakunceda ukwahlukiswa ngokulungileyo kwiindlela ezininzi zokhutshwa. Oko kuyakunceda ngokukhulu kuba le ndawo iyahlukisa iintambo ngokusebenzisa i-vibrations encinci, kuyakuvumela amagama ukuba akunceda ngokusebenzisa amagugu ngaphandle kweeminye. Iindlela zokhutshwa ezisebenzisa le ndlela yokuhlukahluka kwezicathami ziyabona ukulungiswa ngokwamanje kwezithuba zabo, ngokuba ziyakunceda ukwahlukiswa ngokulungileyo ngokukhawuleza kwaye ngeeminye engaphezulu ezingaphambili.
Imishini yesikrinyu yepoliyuyitheni iyabelana nezinhkubo ezinhle ngokuphila kakhulu kwezindlela zokusebenza ngaphansi kwemine ngokuthintela ukwehliswa okungathulwa. Ukuhlinzeka kwematerial ikuvumela ukuphansi kwezici ezincane ukugcina ngelokho okukhulu kusebenza ngendlela enhle ngaphandle kokuthintela. Izivivinyo evela kwezindlela zokusebenza zacele ukuthi izigaba zokulima zisebenza ngokwehlisa izindlela zokusebenza, okungaba yimali engapheliwe yokulungisa imiphatlalo futhi yimali engeke iyasebenze. Kuzindlela zokukhiqiza lapho izibhobho zokulima zingasebenzi ngokuphelele, le ndlela yokusebenza ngokuthembekile iyahlukisa konke. Lapho izikhali zokukhiqiza ziphakeme futhi imizuzu yonke iyahlukile, kudingeka ukuthi izisikrinyu zilinde ngokuthembekile ngosuku lwesuku ukuze kwenzeke ukuthi kuzwakale izikhali zokukhiqiza.
Imigqa yokuhlala eziyinkimbhiso ye-Polyurethane iyindlela ebonileyo ekuphileni kwezinhlanhla, okuqukethwe kakhulu ukuthola imiphumo emihle kuma-operations wet screening okuphathwa ngama-slurries. Izinhlangano zokuthi izinhlanhla ziphume kanjani zibonisa ukuthi le migqa isiza ukuthi izinto ziphume ngendlela ehlukile kusistimu, ukuthula kwezikhathu zokugcina futhi ukwenza ukuthathwa kwezinhlanhla kube lula. Uma kubeke kakhulu indlela izinhlanhla ziphume ngayo kumagqa wokuthathwa, izindzindzaba ziyabona ukuphumelela okuphezulu futhi ukutholwa okuphezulu kwezimali ezinhle ezifihla kusistimu. Kuma-mine futhi kuma-plant processing okusebenza ngama-slurries engqondweni ngemva kanye, lokhu kusho ukuthi kube khona ukuthuthukwa kwezimali futhi ukusebenzisa okuhle kwezinyawo zonke kusistimu yazo.
Imishini yepholiyuthane inezinkcazo zokukhala okungcolisa ukuthi zibe nokuthandana kakhulu nokusebenzela ngokuzenzekile kumatholi aphakeme futhi ahlukene nezinkinga eziningi kusukela kumasebenzi ekushesheni. Abakhululekile kwezindustri babazisa ukuthi le mikhombiso ithula izinkinga ezahlukene noma ikuphela kumatholi aphakeme, okwenza ukusebenza ngokuzenzekile kwezinye izindawo. Izindlela zokuhlanjwa kudinga le nto ngokukhulu ngenxa yoko babuye bakhululeka kwezindlela zokuhlanjwa futhi zibe nezimpawu eziningi zokuthi zihlukene nezindlela zokusebenza. Noma amatholi aphakeme athula kakhulu, konke kusebenza ngokuzenzekile futhi kungenazo izinkinga ezingavumelekile noma izikhathi zokuthi zihlakulwe noma ukukhala kwezokwenza. Kuzindlela zokuhlanjwa lapho kudinga ukuthi amatholi aphakeme aqale ukusebenza ngokuzenzekile kuzindlela zokuhlanjwa, le nto ikhomba ukuthi kusebenza ngokuzenzekile kanye nokuthi kuthinte izinto eziningi kusukela kusebenzweni kwesikhathi esifanele.
Isistimu sokubuya fakwe ngokwesikwele esetshenziswe ku makhasi e-acid polyurethane sibonisa ukuthuthukiswa mkhulu ekulindelweni kwezindleko zokulondoloza, okungaba yindleko yabantu abasebenzisa izinhlelo ngenkathi babo baya kubuye amakhasi. Ngokwemboni yesipho, izinkampani ebuyela kulezi zinhlelo zokubuya zikhona ukuthi izindleko zolondolo zabo ziphelela ngama-40%. Le nto ikhona ukuthi kube yimali lekho etholakala ngokwemva kwezinsuku. Kumaqhina abasebenzisa ukusebenza ngqo, le nto iyadinga inkimbago. Kukusebenza kumhlophe ngokukhulu, ukuthola noma iyure engu-1 ithetha amathousand angu-1 ezindleleni zokuthola amali. Inkinobeko yokuthi ubuye kuphela amakhasi athile futhi akukho makhulu wamakhasi onke ikhona ukuthi kube yinto ehlukile xa kumele ubekelela lezi zindlela zokulayisha izinto ngaphakathi ngokwemva kwezinye izindlela.
Izisikhwama zepolyurethane zilandelayo nezisigaba ezimbili zokwenza uhlelo lwabo lwe-tension okuhle kakhulu lwekhiye ukuthi zidinga ukulungiswa kangakanani. Ukuhlola izici zabo eziphambene nezici zabo ezinhle ukuthi zihlinzekile kakhulu kunemikhawulo yekelesi, ngakho amakhampani ayidingi ukulungisa khona kangakanani. Oku kusobala kakhulu ukuthi izindleko zibe lula kakhulu ngokulungiswa nokuthi izikhawuliwa zidinga ukulungiswa ngokweqile. Ukulungiswa kwehle kude kakhulu njengesikhethelo futhi izinjongo zasebenza ngendlela efudumele futhi ngakho kungabi khona isikhathi eside sokulala isikhwama singasetshenziswa noma singalungiswa.
Ngemva kwezinyanga ezimbalwa, izindlela zokubhokha zokubhokha izinhleke zintshiwe ukwenza amaski aphakathi okunqunyelwa kanye nezilicu, lokungukwesikhundla esibalulekile kubemini odinga ukusebenzela emhlabeni wezilicu. Izilaborithori zilandelana lezi zinhlelo futhi izivivinyo zibonisa ukuthi zihlanza ngokuhlukahluka futhi xa kuzo kuzwa izimo ezinkulu. Okuphumelela kuyo? Iimaski zilinda ngemva kokuqala. Kube lula kubemini xa kusebenzisa izinhleke ezidinga ukuchithwa ngokusebenzisa amakhemikhali asilicu noma alkaline, le ndurable iyahlola konke. Iindlela zokusebenza zilinda ngokunetekisi futhi kungenjalo ukushintshwa kweemaski, lokhu kuthatha imali futhi kuvikele ukuphumelela kwezokwenza.
Izindlelwa zokwenza izinto ezintsha zenza ukuthi kube lula ukudala amapetheni okungenqenqo kakhulu kwezinkawuntuku zokuchithwa kwezimali ebonisa ukuthi yini lezinto ezitholakala phakathi kwezimali. Le petheni haingeli kuphela - kudizaynwa ngokudla ngokudla ngokudla okulawulwa ngokuhle kakhulu okwenza ukuthi lezinto zihambisane ngempela kakhulu ngokuthi zihlukiswe ngokulungile. Amakhampani athintekileyo anquma ukuthi awona amanye amakhampani athintekileyo anquma ukuthi awona amanye. Bafindile ukuthi izinto ezitholakala ziyimpela kakhulu, futhi imisebenzi yabo yonke iyimpela kakhulu kumaqo. Xa amaphini anquma ukuthi abakhulise lezinto ngezidingo eziphathimushelene, kunezinto ezingafuneki kakhulu futhi kunezinto eziphilayo okuphela. Lokhu kuthiwa ukuthi kunezimali eziphakeme kakhulu futhi kunezimali eziphakeme kakhulu.
