Uma i-castor yonakele, indlela evamile yokuyihlola iwukuhlola ukuthi ingaphezulu lesondo seligugile kangakanani. Kodwa-ke, kunesinye isenzakalo esihluke ngokuphelele sokwehluleka esibonakala ensimini: ingaphezulu lethayi liyanamathela, lithambe, futhi liba nemifantu emincane, lize liqhekeke izingcezu ezincane uma likhuhlwa ngesandla, naphezu kokuthi i-castor ibingasetshenziswa isikhathi eside kakhulu.
Okumangazayo nakakhulu ukuthi amanye amadivayisi, naphezu kokusetshenziswa njalo, nawo abhekana nale nkinga.
Kuleli qophelo, imbangela ingase ingabi umqondo wendabuko "wokuguguleka," kodwa kunalokho ukuguga kwe-hydrolytic kwezinto ezithile eziphezu kwesondo ngaphansi kwezimo ezithile.
1. Iyini "i-hydrolysis" yezinto ezisebenzisa amasondo e-castor?
Kalula nje, kusho ukuthi ngemva kokuchayeka isikhathi eside emswakama noma endaweni enomswakama, isakhiwo samakhemikhali sezinto ezithile ze-polymer siyashintsha kancane kancane.
Lolu shintsho luhlukile ekubeni ubuso besondo “buguguleka” phansi.
Ukuguguleka kuvame ukwenzeka endaweni yokuxhumana phakathi kobuso besondo nomhlabathi, kuyilapho i-hydrolysis ihilela izinguquko kancane kancane ezimpahleni ezingokwemvelo zezinto, ngakho-ke zingaqhubeka nokukhula noma ngabe imishini ihlala imile isikhathi eside.
Yingakho abanye abathungi bezimpahla bebonakala “bengasasetshenziswa,” kodwa bathola ukuthi izindawo zabo zamasondo zonakele kakhulu lapho zitholwa eminyakeni eminingi kamuva.
2. Ingabe bonke abathungi be-polyurethane bayasaba i-hydrolysis?
Akunakwenziwa kube yinto evamile.
I-polyurethane akuyona into eqinile ngokuphelele kodwa iwuhlelo lwezinto ezibanzi. Izinhlelo ezahlukene zezinto zokusetshenziswa, ukwakheka, kanye nezinqubo zokukhiqiza zingabonisa ukwehluka okukhulu ekumelaneni ne-hydrolysis.
Ngakho-ke, akulona iqiniso ukuphetha ngokuthi "amasondo e-polyurethane awakwazi ukusetshenziswa ezindaweni ezinomswakama."
Isinyathelo esibalulekile ukucacisa ngesikhathi sesigaba sokukhetha ukuthi ngabe ama-caster azoxhumana isikhathi eside namanzi, izindawo ezinomswakama ophezulu, izixazululo zokuhlanza, noma umusi, bese ukhetha uhlelo lwezinto ezifaneleke kakhulu ngokusekelwe ezimweni zangempela zokusebenza.
Ukusho nje ukuthi “Ngifuna isondo le-PU” kumhlinzeki akunikezi ulwazi olwanele.
3. Kungani indawo enokushisa okuphezulu kanye nomswakama ophezulu iphawuleka kakhulu?
Izinkinga ze-hydrolysis zihlobene kakhulu nezimo zemvelo.
Uma ama-caster evezwa ezindaweni ezimanzi isikhathi eside ngenkathi ebhekene namazinga okushisa aphezulu, inqubo yokuguga kwezinto ezithile ingase iphawuleke kakhulu.
Isibonelo, izindawo zokukhiqiza ezidinga ukuhlanza njalo, izindawo zokugcina izinto ezimanzi isikhathi eside, imishini yokuhlanza, izindawo ezithile zokucubungula ukudla, kanye nezindawo zokusebenza ezinomswakama, kufanele zichazwe kusengaphambili ngesikhathi senqubo yokukhetha.
Ngezinye izikhathi amandla okuthwala umthwalo wemishini wama-casters awayona inkinga nhlobo, futhi yindawo evimbela ngempela izimo zokusetshenziswa kwawo.
4. Uyini umehluko phakathi kwe-hydrolysis kanye nokuguguleka okuvamile?
Ukugqoka okuvamile kuvame ukubonisa izici zokuthinta ezihlukile.
Ngemva kokugingqika isikhathi eside kobuso besondo phansi, ubuso bokusebenza buyancipha kancane kancane, okuyinto elula kakhulu yokuguguleka komshini.
Uma izinto ezibonakalayo ziguga kakhulu, zingabonakala njengobuso obunamathelayo besondo, ukulahleka kokuqina kokuqala, ukuqhekeka kobuso, ukwenziwa kwempuphu endaweni ethile, noma ukuhlukaniswa kwamabhulokhi.
Uma ama-casters engakasebenzi ngamandla amakhulu kodwa ekhombisa izinguquko ezinkulu esimweni sezinto ezibonakalayo, ububanzi bophenyo kufanele bandise kusukela "ekugugeni" kuya ezinkingeni zokuhambisana phakathi kwezinto ezibonakalayo nendawo ezungezile.
5. Kungani abadayisi bezimpahla nabo bengaba nezinkinga?
Iqiniso lokuthi ama-caster awafakwanga emishinini akusho ukuthi isimo sezinto ngeke sishintshe.
Indawo yokugcina izinto enqolobaneni ibaluleke ngokulinganayo.
Uma zivezwa emazingeni okushisa aphezulu, umswakama, ilanga eliqondile, noma ezindaweni ezingafanele ukugcinwa kwezinto isikhathi eside, ezinye izinto ze-polymer zingase ziguge kancane kancane.
Ngakho-ke, ukuze kugcinwe isikhathi eside inani lama-casters, akukhuthazwa ukuhlola kuphela ukuthi ukupakishwa kuqediwe.
Ngaphambi kokulisebenzisa kabusha, ubuso besondo bungahlolwa ukuthi bunamathele yini, buqhekeke, buqine, buthambile, noma buphazamisekile.
Ikakhulukazi uma kunezinto ezigcinwe endaweni ethile ezingakasabalaliswa isikhathi eside, kufanelekile ukwenza ukuhlolwa okulula.
6. Uma ukhetha imishini yokuhlanza njalo, buza omunye umbuzo
Abasebenzi abaningi bokuthenga bazotshela abahlinzeki:
Idivayisi isetshenziswa ngaphakathi endlini
Kodwa isimo 'sokuhlala endlini' sibanzi kakhulu.
Indawo yokugcina ukudla evamile ingaphakathi, kanti indawo yokucubungula ukudla edinga ukugezwa nsuku zonke nayo ingaphakathi. Izidingo zezinto zokukhiqiza ezitholakala ezindaweni ezimbili zingase zihluke ngokuphelele.
Ngakho-ke, uma imishini idinga ukuhlanzwa njalo, kufanele kunikezwe incazelo eyengeziwe mayelana nemvamisa yokuhlanza, ukuthi kukhona yini ukuqongelela kwamanzi isikhathi eside, ukuthi ngabe kusetshenziswa izinto zokuhlanza, nokuthi amasondo asesimweni somswakama isikhathi eside.
Lezi zingcezu zolwazi zivame ukuba yigugu kakhulu kunokumane utshele abahlinzeki ngokusetshenziswa kwangaphakathi.
7. Kutholakale indawo engavamile yesondo, ungasheshi ukufaka esikhundleni sayo ngemodeli efanayo kuphela
Uma iqoqo lamasondo libonisa ukunamathela okufanayo, ukuqhekeka, noma ukuwa, ikhambi elilula ukuwashintsha ngamasha.
Kodwa uma abathungi abasha besasebenzisa uhlelo olufanayo lwezinto futhi indawo yasendaweni ingashintshi, izinkinga ezifanayo zingase ziphinde zenzeke.
Indlela enengqondo kakhulu ukuqinisekisa kuqala:
Iyiphi indawo yomswakama idivayisi ehlala kuyo isikhathi eside?
Ingabe uvame ukuthintana namanzi?
Ingabe ikhona inqubo yokuhlanza?
Ingabe kukhona umhwamuko wamanzi wesikhathi eside eduze kwamasondo?
Ingabe izimo zokugcina impahla endaweni yokugcina impahla ziyafaneleka?
Ngemva kokuqinisekisa lezi zici, hlola ukuthi ingabe izinto eziphezu kwesondo zidinga ukulungiswa.
Kubhale ekugcineni
Ukwehluleka kwama-casters akubangelwa ukusetshenziswa ngokweqile ngaso sonke isikhathi.
Amanye amasondo asebenza ngesivinini esiphezulu nsuku zonke, kodwa ubuso besondo buhlala buzinzile; Amanye amasondo angase angasetshenziswa njalo, kodwa angase aguge ngaphambi kwesikhathi ngenxa yendawo nezinto ezingafani.
Leli futhi iphuzu elivame ukunganakwa ekukhetheni abalingisi:
Ngaphezu kokubuza ukuthi idivayisi inzima kangakanani nokuthi isebenza kuphi, kufanele futhi ubuze ukuthi ama-caster ahlangana kuphi nsuku zonke.
Uma ubuso besondo buqala ukunamathela, ukuqhekeka noma ngisho nokuwa, kungcono ukungasho ngokushesha ukuthi “bubangelwa yikhwalithi yezinto ezibonakalayo ephansi”. Ukuhlolwa okwengeziwe kwendawo yokusetshenziswa kanye nokugcinwa kwempahla kuvame ukwenza kube lula ukuthola imbangela yangempela.
Ukuze uthole ulwazi olwengeziwe, sicela ukhululeke ukuxhumana neQembu le-GLOBE!
