Kwihlabathi lanamhlanje lobunjineli nokwakha, ukukhethwa kwezinto kudlala indima ebalulekileyo ekumiseleni ukuqina, ukusebenza kakuhle kunye nokusebenza ngokubanzi kwesakhiwo. Phakathi kweendlela ezahlukeneyo ezikhoyo,umbhobho ofakwe i-polyurethanekunye nombhobho wolwakhiwo wecandelo elingenanto ziye zavela njengomdibaniso onamandla, zibonelela ngeenzuzo ezininzi kwiintlobo ngeentlobo zezicelo. Eli nqaku lijonga ngokunzulu iingenelo zokusebenzisa umbhobho ofakwe i-polyurethane kwizicelo zolwakhiwo lwecandelo elingenanto, ligxininisa ukubaluleka kwazo ekuphuculeni ukuthembeka kwesakhiwo kunye nobude bexesha.
Funda ngemibhobho efakwe i-polyurethane
Umbhobho ofakwe ngepolyurethane wenzelwe ukubonelela ngokhuseleko oluphezulu ekungcoleni, ekukrweleni nasekuhlaselweni ngamakhemikhali. Umbhobho wenziwe ngezinto zepolyurethane ezisebenza kakuhle ezinamathela kumphezulu ongaphakathi wombhobho ukuze zenze umqobo oqinileyo. Olu yilo lutsha alupheleli nje ekwandiseni ubomi bombhobho, kodwa lukwanciphisa iindleko zokulungisa kunye nexesha lokungasebenzi elinxulumene nokulungiswa kunye nokutshintshwa.
Indima yombhobho wesakhiwo ongenanto
Iityhubhu ezakhiweyo ezinemiqolo, eziquka iimilo ezisikwere, ezizinxantathu nezingqukuva, zisetyenziswa kakhulu kulwakhiwo nobunjineli ngenxa yomlinganiselo wazo ophezulu wamandla nobunzima. Ezi tyhubhu zithandwa kakhulu ngenxa yobuhle bazo kunye nokuguquguquka kwazo, kwaye zifanelekile kwiindlela ezahlukeneyo zokusetyenziswa, kubandakanya izakhelo zezakhiwo, iibhulorho kunye nezakhiwo zoshishino. Nangona kunjalo, zichaphazeleka ziimeko zokusingqongileyo, kwaye ukuqina kwazo kusenokuchaphazeleka ngokuhamba kwexesha.
Iingenelo zombhobho ofakwe nge-polyurethane odityaniswe nesakhiwo secandelo elingenanto
1. Ukumelana nokugqwala okuphuculweyo:Enye yezona nzuzo ziphambili zokusebenzisa imibhobho efakwe i-polyurethane ekwakheni iindawo ezingenanto kukumelana kwayo nokugqwala. I-polyurethane lining isebenza njengesikhuselo esikhuselayo, ithintela ukufuma kunye nezinto ezigqwala ukuba zingangeni kumphezulu wesinyithi. Oku kubaluleke kakhulu kwiindawo ezichatshazelwe ziikhemikhali ezigqwala okanye iityuwa.
2. Ukuqina okuphuculweyo:Ukudityaniswa kombhobho ofakwe i-polyurethane kunye nombhobho wolwakhiwo ongenanto kuphumela kwisisombululo esihlala ixesha elide. Umphetho awuthinteli nje kuphela ukugqwala, kodwa ukwamelana nokukrala, ukuqinisekisa ukuba ulwakhiwo lombhobho luhlala ixesha elide. Oku kuhlala ixesha elide kuthetha ubomi obude benkonzo kunye nesidingo esincinci sokutshintshwa.
3. Ixabiso elifanelekileyo:Nangona utyalo-mali lokuqala lweepayipi ezifakwe kwi-polyurethane lunokuba phezulu kuneepayipi zemveli, ukonga iindleko zexesha elide kukhulu. Iindleko zokulungisa ezinciphileyo, ukulungiswa okuncinci, kunye nobomi benkonzo ende zifaka isandla kwisisombululo esingabizi kakhulu ekuhambeni kwexesha. Ukongeza, ukusebenza okuphuculweyo kwezi payipi kunokukhokelela ekusebenzeni kakuhle, okubangela ukuba iindleko zinciphe ngakumbi.
4. Uluhlu olubanzi lwesicelo:Ukuguquguquka kwemibhobho yesakhiwo esingenanto kunye neempawu zokukhusela ze-polyurethane lining kwenza olu didi lufanelekele uluhlu olubanzi lwezicelo. Ukususela kwiiprojekthi zokwakha kunye neziseko zophuhliso ukuya kwiindawo zoshishino, le mibhobho inokulungiswa ngokweemfuno ezithile, ukuqinisekisa ukusebenza kakuhle kwiindawo ezahlukeneyo.
5. Iingenelo zokusingqongileyo:Ukusebenzisa imibhobho efakwe nge-polyurethane kukwanegalelo kuphuhliso oluzinzileyo. Ngokwandisa ubomi benkonzo yezinto ezakhiweyo kunye nokunciphisa ukuphindaphindwa kwazo, impembelelo iyonke kwindalo esingqongileyo ingancitshiswa. Ukongeza, ukunciphisa isidingo sokugcinwa nokulungiswa kuthetha ukusetyenziswa okuncinci kwezixhobo kunye nokuveliswa kwenkunkuma okuncinci.
Ukuququmbela
Ngamafutshane, ukuhlanganiswa kwemibhobho efakwe i-polyurethane kwizicelo zesakhiwo ezingenanto kunika iingenelo ezahlukeneyo ezinokuphucula ukusebenza, ukuqina kunye nokusebenza kakuhle kweprojekthi zobunjineli. Njengoko amashishini eqhubeka efuna izisombululo ezintsha zokuhlangabezana neemfuno zokwakha zanamhlanje, ukudityaniswa kwezi zinto zimbini ziphambili kuba yindlela ethembisayo yokufezekisa izakhiwo ezihlala ixesha elide nezizinzileyo. Ngokutyala imali kwimibhobho efakwe i-polyurethane, iinjineli kunye nabakhi banokuqinisekisa ukuba iiprojekthi zabo azihlangabezani nemigangatho yangoku kuphela, kodwa zikwamelana novavanyo lwexesha.
