Intshayelelo
Kwishishini leemoto lanamhlanje,igwebu elithambileyo le-polyurethane (PU)iye yaba yinto ebalaseleyo kwiimiqamelo yesihlalo semoto. Indibaniselwano yayo eyahlukileyo yokuthuthuzela, ukuqina, kunye nokuguquguquka koyilo yenza ukuba ibe lukhetho lokuqala kubavelisi beemoto kunye nababoneleli kwihlabathi liphela. Xa kuthelekiswa nezinye izinto zokuthambisa ezifana ne-latex okanye i-polyester fiber,Igwebu elithambileyo le-PUinika ukusebenza okuphezulu, ukusebenziseka lula, kunye nokusebenza kakuhle kweendleko.
Eli nqaku liphonononga isizathu sokubai-polyurethane foam ethambileyoyeyona nto ikhethwayo kwiikhushini zezihlalo zeemoto, iimpawu ezenza ukuba ibe yeyona ifanelekileyo, kunye nendlelaiikhatalyst ze-polyurethanebadlala indima ephambili ekufezekiseni ukusebenza kwefoam okufunekayo.
1. Intuthuzelo egqwesileyo kunye ne-Ergonomics
Uyilo lwezihlalo zeemoto lufuna izixhobo ezinokubonelela ngazo zombiniukuthamba kunye nenkxasoI-PU soft foam inokwenziwa ngokuchanekileyo ukuze kufezekiswe amanqanaba ahlukeneyo obulukhuni, ukuqina, kunye noxinano.
- Ifoam ye-polyurethane enamandla okumelana noxinzelelo (ifoam ye-HR)inika ukuchacha ngokukhawuleza kunye nentuthuzelo egqwesileyo, ilungele izihlalo zomqhubi kunye nabakhweli.
- Ifoam ye-polyurethane eqhelekileyoinika uvakalelo oluthambileyo, olufanelekileyo kwiindawo zokubeka iingalo kunye nemiqamelo engasemva.
Ngokulungisa indlela ebhalwe ngayo—ingakumbi ibhalansi phakathiimpendulo ye-polyol-isocyanatekwaye iimpendulo ye-isocyanate (evuthelayo) yamanzi—abavelisi banokuzilungisa kakuhle iimpawu zefoam ukuze zihlangabezane neemfuno ze-ergonomic.
2. Ilula kwaye iyasebenza kakuhle
Ukunciphisa ubunzima besithuthi yenye yeendlela eziphambili zokuphucula ukonga ipetroli kunye nokuhlangabezana nemigangatho yokukhupha umbane. I-PU soft foam yiilula kodwa yomelele ngokwesakhiwo, inika intuthuzelo ngaphandle kokongeza ubunzima obungeyomfuneko. Isihlalo semoto esiqhelekileyo esenziwe nge-polyurethane foam sinokufikelela kwi30–40% ekhaphukhaphukunezixhobo zokubopha zemveli, ezinegalelo ngokuthe ngqo ekusebenzeni kakuhle nasekuzinzeni kwezithuthi.
3. Ukuqina kunye nokusebenza kwexesha elide
Izihlalo zeemoto zihlala zixinezelekile, zishushu kwaye zingcangcazela ngokuhamba kweminyaka. I-PU soft foam inikaukumelana nokudinwa okugqwesileyo, igcina imo yayo kunye neempawu zokuyigcina ikwimeko entle nangona sele kudlule amawaka emijikelo yokucinezelwa.
Enkosi kwi-optimizediikhatalyst ze-polyurethane, igwebu libonisa isakhiwo seseli esifanayo kunye namandla oomatshini aphuculweyo. Iikhatalysts ezifanaI-MXC-A1 (BDMAEE) or I-MXC-BDMAnceda ukulawula izinga lokusabela kunye nokulinganiselaiinkqubo zokufaka amagwebu kunye nokufaka ijeli, ukuqinisekisa igwebu elihlala ixesha elide elimelana nokugoba kunye nokuguquka.
4. Ukuguquguquka koyilo kunye nokusebenza kakuhle kwenkqubo
I-PU soft foam iveliswa ngokusebenzisaukufutha okukwimowudi or ukufutha kwe-slabstock, evumela abavelisi ukuba benze izihlalo ezineemilo ezahlukeneyo, ubuninzi, kunye namanqanaba okuqina. Ukuguquguquka kwayo kwenza abayili beemoto bakwazi ukudibanisa intuthuzelo kunye nokwakheka okuntsonkothileyo kunye nezakhiwo ezidibeneyo ezifana neebholiti zezihlalo kunye nee-headrest.
Kwimveliso,i-amine kunyeiikhatalyst zesinyithizidlala indima ebalulekileyo ekulawuleni ixesha lokuvuka, ixesha lokunyanga, kunye nobukhulu beeseli zefoam. Ngokusebenzisa ii-catalysts ezisebenzayo, ezingenavumba liphantsi, kwaye ezingenayo i-emission-ezifanaI-MXC-37, I-MXC-R40kunyeI-MXC-B20—abavelisi banokufikelela ekucutshungulweni okuzinzileyo kunye nomgangatho wefoam ohambelanayo ngelixa behlangabezana nemigangatho ye-VOC yeemoto kunye nevumba.
5. Ixabiso eliphantsi kwaye inobuhlobo nokusingqongileyo
Imveliso ye-polyurethane soft foam iphezulu kakhuluengabizi kakhulungenxa yokusetyenziswa kwayo okuphantsi kwezinto eziluhlaza, ukuphiliswa kwayo ngokukhawuleza, kunye nokuhambelana kwayo neiinkqubo zokwenza izinto ngokuzenzekelayoNgaphezu koko, ngokusebenzisaiikhatalyst ezikhupha umbane kancincikwayeii-arhente zokuvuthela ezinobuhlobo nokusingqongileyo (ezifana neenkqubo ze-HFO), iifomyula ze-PU ezithambileyo zanamhlanje zihambelana nemigaqo yokusingqongileyo kunye neenjongo zokuzinza.
Iinkqubo ze-catalyst eziphambili, ezifanaI-MXC-T9kwayeI-MXC-T12, inika ulawulo oluqinileyo lwe-gelation kwaye ivumela i-reaction kinetic echanekileyo, inciphisa amazinga e-scrap kwaye iphucule isivuno iyonke.
6. I-Acoustic kunye ne-Thermal Insulation ePhakamileyo
Ukongeza kwintuthuzelo, i-PU soft foam inegaleloubushushu be-acoustic kunye ne-thermalngaphakathi kwesithuthi. Ulwakhiwo lwayo oluhle nolufanayo lweseli lunceda ukufunxa ingxolo kunye nokungcangcazela, luphucula ukuzola kwekhabhathi. Igwebu likwabonelela ngozinzo lobushushu, lonyusa intuthuzelo yabakhweli kwiimeko ezishushu nezibandayo.
Isiphelo
Ukususela kwintuthuzelo nokuqina ukuya ekusebenzeni kakuhle kwenkqubo kunye nokuzinza,i-polyurethane foam ethambileyoiyaqhubeka nokulawula ishishini lezihlalo zeemoto. Indlela elungiselelwe ngayo ngokwezifiso, ilula, kunye neempawu zayo zoomatshini ezibalaseleyo zenza ukuba ibe yi-izinto ozikhethileyokwiikhushini zezihlalo zeemoto zanamhlanje.
At Izixhobo Ezintsha zeMingxu, sinikezela uluhlu olupheleleyo lweiikhatalyst ze-polyurethaneyenzelwe ukusetyenziswa kwefoam yeemoto—kuqukaI-MXC-A1, i-MXC-BDMA, i-MXC-B20, i-MXC-T12, kunye ne-MXC-R40—ukunceda abavelisi ukuba baphucule ukusebenza kwefoam, banciphise ivumba, kwaye baphucule ukusebenza kakuhle kwemveliso.
Ukuba ufuna izisombululo ze-catalyst ezinokuthenjwaIgwebu elithambileyo le-PUkwimveliso yezihlalo zeemoto,Qhagamshelana nathi namhlanjeukuxoxa ngeefomyula ezenzelwe wena ezihlangabezana nemigangatho yakho yokusebenza kunye neyokusingqongileyo.
