Ekuphononongeni iintlobo ezahlukeneyo zamavili e-urethane, kufuneka sikhankanye iimpawu zawo ezizodwa kunye neemeko zokusetyenziswa. I-Polyurethane njengesixhobo esisebenza kakuhle. Ineempawu zayo zomzimba nezekhemikhali ezibalaseleyo. Ithatha indawo ebalulekileyo kwicandelo lokuvelisa amavili.
Okokuqala. Makhe sijonge amavili e-polyurethane (TPU). La mavili ane-polypropylene okanye i-nylon core. Ngokusebenzisa itekhnoloji yokubumba i-injection yesibini, umphezulu wevili le-polyurethane wenziwa kumda wangaphandle we-core. Amavili e-TPU awaneli nje kuphela ukuba neempawu zokukhusela umgangatho, ukufunxa ukungcangcazela, ukuba awaphawuli kwaye awadayali. Akwanayo nokumelana okuhle nokungqubana kunye nokugqwala. Ayakwazi ukuqengqeleka lula kwiindawo ezahlukeneyo. Ukongeza. Umbala wayo unokuguqulwa ngokwemfuno. Ilungelelaniswe neemfuno zezihlandlo ezahlukeneyo. Nangona kunjalo. Kubalulekile ukuqaphela ukuba kwindawo eshushu. Umthamo womthwalo wevili le-TPU uya kuncitshiswa.
Inyathelo elilandelayo kukuthulula ivili le-elastomer le-polyurethane (CPU). La mavili anombindi wentsimbi okanye we-aluminium njengombindi. Ii-elastomer ze-polyurethane ezitshintsha i-thermoset zenziwe yi-chemical reaction. Zenza umphezulu wevili emva kokunyibilika kumaqondo obushushu aphezulu. Amavili e-CPU aneenzuzo ezifanayo zokukhusela umgangatho, ukungaphawuli kunye nokungadayisi. Ikwamelana ne-UV kwaye ayimelani nokungqubana, nto leyo eyenza ukuba ilungele ukusetyenziswa okufuna intuthuzelo ephezulu yokusebenza. Nangona kunjalo. Ayimelani namanzi ashushu, umphunga wamanzi, njl.njl.… Ke ngoko kufuneka uqaphele xa uyisebenzisa kwiindawo ezithile.
Masithethe ngelinye ivili le-polyurethane eliyi-cast polyurethane (CPU). La mavili asekelwe kwi-thermoset polyurethane elastomers ezibunjwe ngokwekhemikhali. Zineengenelo ezifana nezo zevili le-CPU ezichazwe apha ngasentla, umzekelo, ukukhusela umgangatho, ukumelana nokungqubana, njl. Okuphawulekayo ngakumbi. Ineqondo eliphantsi kakhulu lokuguquguquka okusisigxina, ukumelana nokuqengqeleka okuphantsi. Iyakwazi ukumelana nemithwalo enamandla ngesantya esiphezulu. Ilungele ukusetyenziswa kwiimeko zesantya esiphezulu.
Okokugqibela. Makhe sijonge ivili le-polyurethane (PUE) elinogwebu. Ngesakhiwo salo esingaqhelekanga se-microporous, eli vili libonisa iimpawu ezifana noxinano oluphantsi, ubunzima obulula kunye nokuguquguquka okulula. Likwanazo neepropati ezahlukeneyo ezintle ezifana nokuthwala umthwalo ophezulu, ukuthamba okuphezulu kunye nokumelana nokugoba. Ezi mpawu zamavili e-PUE ziwenza abe lukhetho olufanelekileyo lwezinto ezisetyenziswa xa kusenziwa ii-casters. Nokuba kukufunxwa kakuhle kunye namandla okanye ukudambisa ukungcangcazela kunye nokuthomalalisa. Zonke zinokubonisa izibonelelo zazo ezizodwa.
Ngokubanzi. Amavili ePolyurethane, kunye nokusebenza kwawo okugqwesileyo kunye neentlobo ezahlukeneyo, asetyenziswa kakhulu kwiindawo ezahlukeneyo. Ukusuka kumavili eTPU akhusela umhlaba kwaye afunxe ukutshatyalaka. Ukuya kwi-UV kunye nokumelana nokungqubana kwevili leCPU. Ngaphezulu kobunzima obuphantsi kunye nobunzima obuphantsi bevili lePUE. Uhlobo ngalunye lwevili le-polyurethane ludlala indima ebalulekileyo kwintsimi yalo. Ukukhetha ivili le-urethane elifanelekileyo kwiimfuno zakho. Ayinyusi nje kuphela ukusebenza kakuhle. Ikwabonelela ngamava akhululekileyo nakhuselekileyo.
