Kwindawo yanamhlanje yemizi-mveliso neyezorhwebo, amavili enziwe ngezinto ezahlukeneyo asetyenziswa kakhulu kwiimeko ezahlukeneyo ngenxa yeempawu zawo ezizodwa. Ukusuka kumavili e-nylon, amavili e-nylon axonxiweyo (MC). Ukuya kumavili erabha aqinileyo, amavili erabha athambileyo. Emva koko ukuya kumavili erabha aqonxiweyo, amavili erabha aqonxiweyo achasene nokuma. Kunye namavili epompo kunye namavili esinyithi axonxiweyo. Ngalinye lala mavili lahlukile kwaye liyanelisa iintlobo ngeentlobo zeendawo zomhlaba ezintsonkothileyo kunye neemfuno zokuthwala umthwalo. Okulandelayo. Siza kugubungela nezinye iintlobo ezininzi zamavili.
Ivili lePolypropylene, elaziwa kakhulu ngokuba livili lePP
I-Polypropylene yinto ye-thermoplastic eyaziwa ngokuchasana kwayo nempembelelo, ukuchasana nokugqwala, ukuchasana nokungqubana, ukungaphawuli, ukungangcolisi kunye neempawu ezingezizo iityhefu. Le nto ayinavumba, ayixutywanga kwaye ayixutywanga nezinto ezininzi ezirhabaxa. Nangona kunjalo, ayinazo ii-oxidizing agents ezinamandla kunye nee-halogenated compounds. Amavili e-polypropylene afanelekile kumaqondo obushushu aqala kwi--20°C ukuya kwi-+60°C. Nangona kunjalo, xa amaqondo obushushu angaphakathi engaphezulu kwe-+30°C, amandla ayo okuthwala aya kuncitshiswa.
Ivili lePolyurethane
I-Polyurethane (TPU) yi-thermoplastic polyurethane. La mavili ane-polypropylene okanye i-nylon core. I-Polyurethane ifakwa okwesibini kwi-edge yangaphandle ye-core ukuze yenze ubuso bevili. Amavili e-Polyurethane aneempawu ezintle zokukhusela umgangatho, ukufunxa ukungcangcazela, ukuba awaphawuli, awadaki, ayanwebeka, ayaguquguquka kwaye ayamelana nokugqwala zizinto ezininzi ezirhabaxa. Ukongeza, ikwamelana namanzi ashushu kunye nomphunga wamanzi phantsi kweemeko ezithile. Ukumelana kwayo nokuqengqeleka kuphantsi. Ifanelekile kwiindidi ezahlukeneyo zemigangatho. Imibala ingenziwa xa iceliwe. Ihlangabezana neemfuno ezahlukeneyo. Ii-monowheels ze-polyurethane ze-thermoplastic zifanelekile kumaqondo obushushu aqala kwi--45 °C ukuya kwi-+90 °C. Nangona kunjalo, amandla okuthwala umthwalo ayancipha kumaqondo obushushu angaphezulu kwe-+35 °C.
Ivili le-Elastomer leCast Polyurethane (CPU)
Ii-elastomers ze-polyurethane ezixotyulweyo (ii-CPU) zii-elastomers ze-polyurethane ezifakwa kwi-thermosetting ezibunjwe yi-chemical reaction. Izinto ezisisiseko ziquka ii-polyester polyols, ii-diisocyanates kunye nee-glycols. Olu hlobo lwevili lusebenzisa i-iron okanye i-aluminium core njenge-core, kwaye i-polyurethane igalelwa kumphetho wangaphandle we-core. Umphezulu wevili wenziwa ngokuthambisa kubushushu obuphezulu. Amavili e-polyurethane athululweyo akhusela kakhulu umhlaba, afunxa ukungcangcazela, awaphawuli, awadayali, ayamelana nokugqwala kakuhle, ayanyamezela ukugqwala zizinto ezininzi ezinoburhalarhume, ayamelana ne-UV. Ukongeza. Inezinga eliphezulu lokuthuthuzela kokusebenza, iyamelana nokuqengqeleka okuphantsi. Ayivelisi ubushushu xa ithwaxwa yimithwalo enamandla. Umbala umhlophe. Ifanelekile kumaqondo obushushu aqala kwi--30°C ukuya kwi-+70°C. Ukuya kuthi ga kwi-+90°C ixesha elifutshane. kumaqondo obushushu angaphantsi kwe--10°C. Ukuqina kwayo kusebenza kakuhle.
Elinye ivili le-polyurethane (CPU) elenziwe nge-cast
La mavili e-polyurethane atyhidiweyo (i-CPU) asekelwe kwi-thermosetting polyurethane elastomers ezibunjwe ngokweekhemikhali. Zakhiwe kwi-polyester polyols, diisocyanates kunye ne-glycols. Ineempawu zokukhusela umhlaba, ukungaphawuli, ukungadaya, ukumelana nokungqubana, ukuthamba okuhle kunye nokuxhathisa ukugqwala kwezinto ezininzi ezinoburhalarhume. Ikwamelana ne-UV. Ineqondo eliphantsi kakhulu lokuguquguquka okusisigxina. Ukumelana nokuqengqeleka okuphantsi. Ukuveliswa kobushushu okuncinci xa kuphantsi kwemithwalo enamandla. kwaye iyamelana ne-hydrolysis. Ifanelekile ngokukodwa kwisantya esiphezulu ukuya kuthi ga kwi-16km/h. Imibala ingalungiswa xa iceliwe. Uluhlu lobushushu olufanelekileyo luphakathi kwe--45°C kunye ne-+90°C, kunye nexesha elifutshane elingaphezulu kwe-+90°C.
Ivili lePolyurethane (PUE) elinogwebu
Amavili e-polyurethane ane-foam (PUE). Akwaziwa ngokuba yi-microporous polyurethane. Yi-block polymer. La mavili abonakala ngokuthamba okuhle, iimpawu zawo zomzimba zidlula ezo zezinye ii-elastomers ezine-microporous ezinobunzima obufanayo. Amavili e-polyurethane ane-foam aneempawu ezilungileyo ezifana nobunzima obuphantsi, ubunzima obulula, ukuguquguquka lula, ukubumba okulula, ukumelana nempembelelo, ukufunxwa kakuhle kwe-acoustic, umthwalo ophezulu, ukuthamba okuphezulu, ukumelana nokugoba okuhle, ukumelana noxinzelelo oluphantsi, ukumelana nokukrazuka, ukumelana nokukrazula, ukumelana nemisebe kunye nokufunxwa komothuko kunye ne-buffer. Inoluhlu olubanzi lobunzima. Ukusuka kwi-Shore A10 ukuya kwi-100, ilungele ukusetyenziswa njengezinto ze-caster.
Lilonke. Ivili ngalinye lineseti yalo. Elinye lineempawu zalo ngokwezinto ezisetyenziswayo, ukusebenza kunye nendawo efanelekileyo. Xa kukhethwa amavili, kufuneka sidibanise oku ngokusekelwe kwiimeko ezithile zokusetyenziswa kunye neemfuno. Ukuqinisekisa ukuba ivili elifanelekileyo likhethiwe. Ke ngoko, lisebenza kakuhle.
