Kulungiselela ukuba kukhona kahle kwezimali zokugcina ama-roll zeziphetjana eziphathelene kakhulu uma sifuna ukuba zilinde isimo. Zinkona izimo ezidinga amandla aphakathi kwe-60 ukuya kwe-80 ezingaphandle. Ukuze zilinde kule ndawo enempela fayela ukuba zingaphansi noma zingakhali, okungakwazi ukuvulelwa ngoba uma zilungile, kungenzeka ukuthi kuyilandelwa. Ukulungisa ukwehlile kuyafana nezidingo. Thatha ukuya kwe-40% ukuya kwe-60% yezimo zokwehlile ukuze izimali zingathenga amandla noma zingaphansi kabonakalayo, okubonke kungcono kakhulu kwezimali. Ukuze kwezimali kulezindawo ezilungisa izimo zokugcina kuyenza isisho esikhulu kakhulu kahle kazo kanye nezimo zokusebenza, ngakumbi uma akukho onke amandla ukuthi ubeke amandla esikhathini esingatholanga noma amandla athathwe ngendlela engavumelekileyo.
Amashidi e-polyurethane adinga ukuvikelwa ekukhanyeni kwe-UV kanye nelanga eliqondile uma sifuna ukugwema izinkinga zokuwohloka kwe-polymer. Ukuchayeka elangeni kuyingozi kakhulu kulezi zinto. Ucwaningo lukhombisa ukuthi ukuzishiya elangeni isikhathi eside kunganciphisa amandla azo cishe ngo-30%. Ngakho-ke ukugcina lawa mashidi endaweni enomthunzi kunengqondo, noma okungenani ukuwamboza ngokuthile okuvimba imisebe ye-UV. Ukusetha uhlobo oluthile lwesivimbelo noma isistimu efanele yokugcina isebenza kahle ukuze ugcine leyo misebe eyingozi ikude nokugcina ikhwalithi yamashidi ngokuhamba kwesikhathi. Kubakhiqizi nanoma ubani osebenza ngemikhiqizo ye-polyurethane, ukuthatha lezi zinyathelo kusiza ukuqinisekisa ukuthi impahla ihlala iqinile futhi isebenza njengoba kulindelekile phakathi nokugcinwa nalapho ekugcineni isetshenziswa.
Izindanda zokugcina zinjongo ebalulekile ukugcina izicathami zepolyurethane kwi-diameter echanekile xa kuzwa kuzwakala, okuqinisekisa ukuthi kwehliswe kakhulu umahluko. Kudingeka ukuba kuhambelane ngeyizindanda ukuthi kudingeka kuhambelane nesibanzi sezicathami ukuze amandla ayikhathalise amandla. Abasebenzisa inkampani ngokubanzi kudinga ukuthi usebenzise izinto ezinhle kakhulu kulezi zindanda ngoba lezo zindanda eziyisisekelo kungase kuhlulekile ngokugcwele ngokugcwele kwezimali. Uma abasebenzisa inkampani kuyifowlo lokhu, izindanda zazo zizoba nezimo eziphumelelayo ngemva kwesikhathi eside. Izindanda zizoba zinezimo eziphumelelayo futhi kungase kuhlukumezi emva kokugcinwa ngemva kweminyaka eyi-6 noma ukulandelana kwezinye izindawo, okuqinisekisa ukuthi kwehliswe kakhulu umphathi wokwenza nekuhlangene nabo.
Ukuhlola imikhombandlela emide ye-poliyurethane, abantu abaningi bahlola ukulola ngokovunyelwe ngisho nokuthi kuthatha ukwelapha kwezimpawu futhi kakhulise ukuba kungaphakathi. Imikhombandlela embali sometimes kudinga ukulola ngokushonile. Kodwa xa kwenziwa lokhu, kubaluleke ukuthi ubindle amandla ngokulinganile emaphakathini ukuze akukho lutho lukhumele kaphakathi. Abantu abaningi abasebenzisa lezi zinto ngemva nemva baya kujikeleza izinto ezijikelezwayo ngokuthi yini indawo enembala ngempela kabefore ukuthi iziqondiso zokuhlola ngokuvunyelwe noma ngokushonile ziyakufuneka kahle kuzo zonke izimo. Kudingeka ukuthi lenqubo iyakhiwe ngokucophelela ngisho nokuthi uma imikhombandlela ayahlakahlakelwa ngokucophelela, ingaphela lezo futhi kuthathe isimo sezo bani noma sebenza xa esetshenziswe.
Uma sifuna ukumema le miphumela eziphambene nezimalayezo zokugcinwa kwezimalayezo zethu zokwenza polyurethane, ukunika amakhono aphakade ayindlela ebalulekile. Kungenxa yale mehla, kungcono ukuba uyisalela ngemapha kwezingu-12 kuya kwezingu-24. Uma le zimalayezo ziphakathiwe ngokufanayo, ziphuza ukushintsha isimo ngokukhulu. Inani eliyini lekhono lokuvela kwenza ukuba amadoti aphume ngokuvamile kuleli zinto, lokhu kwenza ukuba kungena amakhaza futhi ukuvikela ukuthi amaphfungu achaze. Izinhlangano ezenziwe kuleli qembu zibonisa ukuthi le zimalayezo ezigcinwe ngekungabi noma yiliphi isalelo ziphuza ukushintsha isimo ngokukhulu nge-20% ngokwezibonelo ezitholwe. Ngakho-ke ukugcina le zinto ngokuthi ziphakathi kungcono ukwenza umsebenzi ongcono; kungcono ukuthi kwenzeke ngokomno kakhulu uma sicinga ngendlela ethile lezinto zizosalela b4 kuthathwa futhi zilokotho.
Kunengqondo ukugcina amashidi e-polyurethane kude nezinye izinto, ikakhulukazi lezo zingxenye zensimbi ezisetshenziswa eminyango enama-roller-up, ngoba amakhemikhali angase asabele futhi abuthakathaka impahla ngokuhamba kwesikhathi. Ukwakha uhlobo oluthile lwesithiyo phakathi kwazo noma ukudala izindawo zokugcina ezihlukene kuyasebenza kahle ekuvimbeleni le nkinga yokuxuba. Lapho izindawo zokusebenzela zinamabhodi e-polyurethane nezinto ezihlukahlukene zezimboni ndawonye, kuyazuzisa ukuqeqesha abasebenzi njalo. Ukuqeqeshwa kuhlanganisa ukuthi kungani ukugcina izinto zihlukanisiwe kubaluleke kangaka futhi kufundisa abasebenzi indlela yokugcina konke ngendlela efanele ngaphandle kokubeka engozini ukulimala. Ukufaka zonke lezi zindlela ekuphileni kusiza ekuvikeleni ikhwalithi yamashidi e-polyurethane ukuze ahlale eqinile futhi enokwethenjelwa lapho edingeka kakhulu.
Izimpahla zokuzivikela zibaluleke kakhulu lapho kuthuthwa amashidi e-polyurethane ngoba lezi zinto zingaba yingozi kakhulu uma ziphathwa kabi. Izisebenzi zidinga amagilavu afanele okuvikela isikhumba, ukuvikela amehlo emfucumfucwini endizayo nezicathulo eziqinile ukuze zivimbele ukulimala kwezinyawo ngenxa yemithwalo eyehla. Lapho abasebenzi begqoka njalo le mishini lapho behamba kulezo zindilinga ezisindayo, inani lezingozi lehla kakhulu ezikhungweni eziningi. Ukuqeqesha okuhle nakho kwenza umehluko. Izinkampani ezifaka imali emhlanganweni wokuphepha ovamile lapho abasebenzi befunda khona ukuthi kungani imishini yazo isebenza empeleni zibona izehlakalo ezimbalwa endaweni. Ukulandela imithetho ye-OSHA akuyona nje ukuhlola amabhokisi. Le mithetho ikhona ngoba iye yafakazelwa ngokuhlangenwe nakho ukuthi igcina izindawo zokusebenza ziphephile kubo bonke abathintekayo ngokuhamba kwesikhathi.
Ukufunda ukwakhiwa kahle kwekhiye kuyindlela esenza ngayo ubukhulu ngokusebenzisa le rolodlo eziphakeme zamaphoyintshontsho. Abasebenzi kufuneka bafunde ukuba baphindelele emakhiwini ngenkawo yokusebenzisa imifuba yabo, into engiyindlela elula kodwa esenza ukuthi kuthuliwe kakhulu ukwehliswa kwezikhumba ngokudlule kwezinsuku. Xa kufika kokuhlamba le rolodlo, kubaluleke futhi ukubonisa abantu kakuhle kanjani ukwenza oku ngokuhlonipha njengoba uma ukuphazamise kuhluka ngokugcwele, kungakhathazeka ukuthi kuhlanganise kanye nabo. Iziphanti ezithunyelwe ngegceke, njengekhiye yemishini noma izindambo zokuhlamba, kunciphisa kakhulu ukwenza oku ngokugcwele. Amakhambi amaningi awona amathuba okwenza amagugu ethu ahlukile ngemuva kokuthi kumele kwenziwe ukuthola le ziphanti, okubonisa ukuthi ngizikhathi kumele kuthathwe amaphela okuqala ukuthi kuthathwe amaphela ngokugcwele.
Ukucasha ngokokhuni kusiza ukugcina imikhawulo yesithapho se-polyyurethane kahle ngeminyaka. Ukubheka kancane ngokweqhethwana ngalinye iintsuku kuthola izinkinga ngaphambi kokuba kude kube yimali, njengoko xa ikhala liyaphula okanye amakhuku aya kubonakala kwenqanawe. Kufuneka le zinkinga zilungiswe ngokokhuni ukuba sithintele izinkinga eziphezulu emva kwezinye izikhathi. Abanye abantu bathanda ukusebenzisa izibhalo eziyophula ngokokhuni kubonisa izinkinga. Le zibhalo eziyophula zibonisa izinto onke amehlo ethshintsha, njengoko xa ikhemikhali liyaphula isithapho ngokufihlekileyo. Ukubhala ngokokhuni yonke into emva kokekho kuyakusiza ukulandelela ukuthi isithapho siyaphila kanjani ngokweminyaka. Ngaphezulu koko, ukubheka amanqaku ezingaphambili kuthola izinto ezingekho kubonakala ngokwokubona, okukhomba ukulungiswa kwezinye izikhathi.
Ukuhlanza kahle ukugcina ama-roll ngamaphakathi akho aye kudinga okuningi kune ukuthi ubalele kulo msebenzi wokugcina. Kudinga isicathami esijabulisayo futhi ukulandela izinto ngokucophelela. Le methode ye-FIFO iyasebenza kahle lapho sibuya faka amadoti esidansi ngaphambi kokuthi kwe amanye athile ahlale kancane. Akukho onke amathisela ukuthi ahluleke lapho engenza ukuthi asebenziswe kahle endaweni enye. Ukubhala ngokuhle indlela ethintekayo yokugcina leli zinto futhi ukuthi kuthathwa kanjani lapho kuthathwa kunguchuma kuphela, kodwa kunceda futhi ukuthi izilawuli zokugcina zisebenze ngendlela elula. Futhi yini, izilawuli zonke zasekhaya zimeva ukuthi zibuye sebenzisa izici zokugcina izinto ngokwamanje. Lezi zici zinceda kokuqokelela, zinceda kweqile ukuthi kuthathwe amadoti, zinceda ukuthi sithathe amaphela kakhulu, futhi zinceda ukuthi kube lula kakhulu kubo bonke abasebenzisa kuzilawuli.
