Ezimweni ezifana nokuhambisa ngomshini, ukuphathwa kwemishini yezithombe, kanye nokushintsha kwezindawo zokugcina impahla, ama-caster awadingi nje kuphela ukukwazi ukuthwala isisindo, kodwa futhi adinga ukucabangela ukumelana nokuguguleka, ukuthula, ukunyakaza okuzinzile, kanye nokuphila kwesevisi. Isizathu esiyinhloko sokuthi ama-caster aqondisa izinto ngendlela ethule e-polyurethane asetshenziswa kabanzi ukuthi ahlanganisa izakhiwo zezinto ezibonakalayo kanye nomklamo wesakhiwo ngendlela elinganiselayo. Kalula nje, angenza ukunyakaza kwedivayisi kube lula futhi kugcine ukusebenza okuzinzile ezindaweni eziningi eziyinkimbinkimbi.
1. Izakhiwo zezinto ezilinganiselayo, ukulinganisela ukumelana nokuguguleka, ukunciphisa umsindo, kanye nomthamo wokuthwala umthwalo
I-Polyurethane, eyaziwa nangokuthi i-PU, iyinto esetshenziswa kakhulu njenge-polymer. Inzuzo yayo isebangeni layo lokusebenza elikhulu elilungisekayo, elingenziwa lithambe ukuze kuthuthukiswe imiphumela yokunciphisa umsindo nokunciphisa umsindo, noma kube nzima ukuthuthukisa ukumelana nokuguguleka kanye nomthamo wokuthwala umthwalo.
Uma kuqhathaniswa nerabha evamile, i-polyurethane ayigugi kakhulu futhi ayigugi ngokushesha ngenxa yokugingqika isikhathi eside; Uma kuqhathaniswa namasondo enayiloni, inokuguquguquka okungcono, ayithinti kakhulu phansi lapho ihamba, futhi inomsindo ophansi. Ngenxa yalokhu, ama-polyurethane casters avame ukusetshenziswa ezindaweni zokusebenza ezidinga kokubili ukuvikelwa komhlaba kanye nokulawulwa komsindo.
Ngokwesakhiwo, lolu hlobo lwe-caster luvame ukusebenzisa i-core yesondo lensimbi ehlanganiswe nesendlalelo sokumboza se-polyurethane. I-core yesondo lensimbi inesibopho sokunikeza amandla okusekela, kuyilapho ungqimba lwangaphandle lwe-polyurethane luthinta ngqo umhlabathi futhi lunesibopho sokumuncwa kokushaqeka, ukunciphisa umsindo, kanye nokumelana nokuguguleka. Ngemva kokuhlanganiswa kwalokhu okubili, amandla okuthwala umthwalo kanye nokuzinza kwama-caster kuzoba ngcono.
2. Umphumela omuhle wokuthulisa, ofanele izigcawu ezinezidingo eziphezulu zemvelo
Inzuzo enkulu yama-caster aqondisa izinto ngokuthula e-polyurethane umsindo ophansi ngesikhathi sokusebenza. Isizathu asiyinkimbinkimbi: i-polyurethane ngokwayo inezinga elithile lokunwebeka, elingamunca ingxenye yomthelela ovela emhlabathini lapho amasondo egingqika, okunciphisa ukudlidliza nomsindo obangelwa ukushayisana okunzima.
Kumasondo aqinile avamile, izikhala ezincane noma ukungalingani phansi kungabangela kalula imisindo yokugingqika ebonakalayo lapho uhamba; Amasondo e-polyurethane, ngenxa yokuthintana kwawo okuthambile kanye nokunyakaza okubushelelezi, ngokuvamile akhiqiza umsindo ophansi ngaphansi kwezimo ezifanayo zomthwalo.
Lolu hlobo lwesici lufaneleka kakhulu ezindaweni ezidinga ukuthula, njengokuphathwa kwemishini yezithombe, ukunyakaza kwemishini yokuhlola, ukuhanjiswa kwemishini ngaphakathi endlini, kanye nezinye izindawo zokukhiqiza ezidinga indawo yokusebenza. Idivayisi ithule kakhulu uma inyakaziswa futhi iyasiza ekunciphiseni umthelela wokudlidliza emishinini uqobo.
3. Isakhiwo esiqondisayo senza ukunyakaza komugqa oqondile kuzinze kakhudlwana
Ngaphezu kwezinzuzo zezinto ngokwazo, ukwakheka kokuqondisa nakho kuyisici esibalulekile salolu hlobo lwe-caster. Isondo elibizwa ngokuthi eliqondisayo libhekisela esondweni elingahamba phambili kuphela ohlangothini oluqondile futhi elingenakukwazi ukujikeleza ngokukhululeka njengesondo elijwayelekile.
Inzuzo yalesi sakhiwo ukuthi sihamba ngokuqina emgqeni oqondile, ikakhulukazi esifaneleka ezimweni ezifana nokuthuthwa komzila oqondile, ukusunduza imishini phambili nangemuva, kanye nokunyakaza kwamathuluzi omugqa wokukhiqiza. Idivayisi ayithambekele kakhulu ekuphambukeni ngesikhathi sokunyakaza futhi kulula ukuyilawula lapho isebenza.
Uma indawo yokusetshenziswa ihilela kakhulu ukuhamba ngendlela enqunyiwe, njengemigqa yokuhambisa, iziteshi zokudlulisa imishini esindayo, ukuphathwa kwezithombe okusizwa umzila, ama-caster aqondisa indlela ngokuvamile afaneleka kakhulu kunama-caster ajikelezayo. Nakuba ukuguquguquka kwayo kungephezulu njengokwamasondo ajwayelekile, inezinzuzo eziningi ekuzinzeni nasekulawuleni indlela.
4. Ukumelana nokushisa okuphezulu, ukumelana ne-hydrolysis, ukumelana nowoyela, kanye nokuzivumelanisa nezimo okunamandla kwemvelo
Izidingo zama-casters ezimweni zezimboni zivame ukuhlanganisa hhayi ukuhambahamba kuphela, kodwa futhi nokuzivumelanisa nezimo eziyinkimbinkimbi. Ama-casters aqondiswe ngendlela ethule e-polyurethane nawo anezinzuzo ezibalulekile kulokhu.
Okokuqala, inokumelana okuhle nokuguguleka futhi ayithambekeli ekuqhekekeni okukhulu noma ekugugeni ngokushesha ngemva kokusetshenziswa isikhathi eside. Okwesibili, iyakwazi ukuzivumelanisa kahle nezimo ezimanzi, izindawo ezimanzi, kanye nezinga elithile lokungcoliswa kwamafutha, okwenza ivame kakhulu ekuthuthweni kwemishini, ezindaweni zokugcina impahla, ezindaweni zokusebenzela, nakwezinye izimo.
Izinto ze-polyurethane eziguqulwe kancane nazo zinokumelana okuhle nokushisa futhi zingazivumelanisa nezimo zokusebenza ngaphakathi kwebanga elithile lokushisa. Lokhu kuwusizo kakhulu kwezinye izindawo zokusebenzela zokushisa okuphezulu noma izimo zokusetshenziswa ezinokuxhumana kwesikhashana komthombo wokushisa.
5. Uma ukhetha, gxila kulezi zinhlaka ezintathu
Bheka umthamo wokuthwala. Lapho ukhetha amasondo, akwanele ukubheka ukubukeka nobukhulu bamasondo kuphela, kodwa okubaluleke kakhulu, ukubona ukuthi umthwalo olinganisiwe wesondo elilodwa ungahlangabezana yini nezidingo zesisindo esiphelele semishini. Ngokuvamile kunconywa ukushiya umkhawulo othile ngokusekelwe esisindweni sangempela, esiphephile futhi esihlala isikhathi eside.
Okwesibili, hlola ububanzi besondo kanye nobukhulu bomphezulu wesondo. Uma ububanzi besondo bukhulu, kulula ukulisunduza futhi kungcono ukulidlula; Kodwa uma isikhala sokufaka silinganiselwe, kudingeka kulinganiswe phakathi kosayizi nezidingo zokusetshenziswa.
Okwesithathu, hlola ubulukhuni. Ubulukhuni obuphezulu, ngokuvamile obungagugi kakhulu futhi obuthwala umthwalo; Ubulukhuni obuphansi buzoholela ekubambeni okungcono kanye nemiphumela yokunciphisa umsindo. Uma umhlabathi ungasicaba ngokwanele, ifomula ye-polyurethane enokuguquguquka okungcono ingabekwa phambili.
6. Yiziphi izinzuzo zayo uma kuqhathaniswa nabalingisi abavamile?
Uma kuqhathaniswa namasondo erabha avamile, amasondo e-polyurethane avame ukumelana nokuguguleka okungcono futhi ahlala isikhathi eside. Uma kuqhathaniswa namasondo e-nylon, asebenza kangcono ngokwezinga lokunciphisa umsindo, ukumuncwa kokushaqeka, kanye nokuvikelwa komhlabathi.
Ngaphezu kwalokho, umehluko phakathi kwama-caster aqondisa indlela kanye nama-caster ajwayelekile kufanele futhi uhlukaniswe. Amasondo e-Universal aguquguquka kakhudlwana futhi afaneleka kakhulu ezimweni ezidinga ukujikwa njalo; Amasondo aqondisa indlela afaneleka kakhulu ezimweni lapho imigqa eqondile, ukuzinza, kanye nokulawula indlela kubalulekile. Ezinhlelweni eziningi zokuhambisa imishini kanye nokuphatha imishini, ama-caster aqondisa indlela empeleni asebenza kahle kakhulu.
Isiphetho
Sekukonke, izinzuzo zobuchwepheshe zama-caster aqondisa izinto ngokuthula e-polyurethane zibonakala kakhulu ezicini ezine: izakhiwo zezinto ezilinganiselayo, ukusebenza okuthule, ukunyakaza okuqondile okuzinzile, kanye nokuzivumelanisa nezimo kwemvelo okuqinile. Kumadivayisi adinga ukulinganisela ukulawula okuthwala umthwalo, ukumelana nokuguga, ukuthula, kanye nokuqondisa, kuyisinqumo esiwusizo.
Ekuthengeni kwangempela, kunconywa ukukhetha imishini ngokusekelwe esisindweni sayo, izimo zomhlabathi, indlela yokuhamba, kanye nokusetshenziswa kaningi. Ukukhetha amasondo afanele akugcini nje ngokuthuthukisa ukusebenza kahle kokunyakaza kwemishini, kodwa futhi kunciphisa izindleko zokulungisa nokufaka esikhundleni sayo esigabeni esilandelayo.
