Iipolyurethanes zifumaneka kuyo yonke indawo kubomi banamhlanje;isitulo ohleli kuso, ibhedi olala kuyo, indlu ohlala kuyo, imoto oyiqhubayo - zonke ezi zinto, kunye nezinye izinto ezingenakubalwa ozisebenzisayo ziqulethe iipolyurethanes.Eli candelo liphonononga ezinye zezicelo eziqhelekileyo ze-polyurethanes kwaye libonelela ngokuqonda ekusebenziseni kwazo.

Iingubo

Iingubo ezininzi zanamhlanje, nokuba zezezithuthi kunye neentambo, imigangatho kunye neendonga, okanye iibhulorho kunye neendlela, ziqulethe i-polyurethanes, ekhusela ngokukhuselekileyo nangempumelelo indawo evezwe kwizinto kunye neendlela ezahlukeneyo zongcoliseko, ukuze zibukeke ngcono kwaye zihlala ixesha elide.

Ukuqina, ukuxhathisa umhlwa kunye nokumelana nemozulu ye-polyurethanes kubenza bafanelekele ukugquma zonke iintlobo zemigangatho.Usetyenziso lususela kulwakhiwo lwekhonkrithi olufana neebhulorho kunye nezakhiwo zemoto, ukuya kwiikhareji zikaloliwe zentsimbi kunye nefanitshala yamaplanga.

Izincamathelisi / izibophelelo

Iipolyurethanes ziguquguquka kakhulu kangangokuba zikwafumaneka ngohlobo lweeglue ezinokubopha ngokukhuselekileyo kunye nezinto ezahlukeneyo, ezinje ngomthi, irabha, ikhadibhodi okanye iglasi.

Iiprojekthi zokwakha, ngokukodwa, zisebenzise i-polyurethane glues.Abavelisi bokupakisha kunye nabavelisi befanitshala yangaphandle, bobabini abafuna ukomelela kunye nokomelela kwiimveliso zabo, baxhomekeke rhoqo kwizinto zokuncamathelisa i-polyurethane.

Iipolyurethanes ziluncedo kwimveliso yezicelo ezitsha eziphuhliswe kwizinto ezilahliweyo kunye nezisetyenzisiweyo.Umzekelo, amatayara ezithuthi angaphelelwayo enziwe abe ngamabala okudlala abantwana, amabala emidlalo okanye imiphezulu yamabala emidlalo ngenxa yeempawu zokuncamathelisa zepolyurethane.

Iimpawu ezibophezelayo ze-polyurethane zivule amathuba amatsha okudibanisa iintlobo ezahlukeneyo zezinto.Izicelo ziquka iibhodi ezikumgangatho ophezulu zokwenza iikhabhathi, iindawo zokusebenza kunye nomgangatho wekhitshi.Ngokufanayo, i-polyurethanes ingasetyenziselwa ukubopha kunye imvuthuluka ye-foam ukuvelisa i-carpet underlay.Enjalouphuhliso lokurisayikilishaukunceda ukugcina ubutyebi bendalo boMhlaba.Ishishini lentsimbi lisebenzisaiidiisocyanatesnjengesiseko sezibophelelo ukwenza imibumbo yokuphosa.

Iipropathi zokuncamathelisa zePolyurethane zikwasetyenziswa ekwenzeni iimveliso zokhuni ezidityanisiweyo eziphezulu.Iimveliso zomthi ezidityanisiweyo ezenziwe kwizibonelelo zamahlathi ezizinzileyo ziyindlela yokwenyani kwiimveliso zephaneli eziveliswe kwimithi emikhulu esele ikhulile ethathe iminyaka ukukhula.Esi senzo siqinisekisa ukuba kulinywa imithi emininzi kunaleyo ivunwayo kwaye, ngokusebenzisa imithi emitsha ekhula ngokukhawuleza efunxa icarbon dioxide eninzi kunemithi esele ikhulile, inceda ekunciphiseni ukutshatyalaliswa kwamahlathi.
