umcane wamavuthi weziqayi lwe-pu olunxibelelwe kwisekhewu
I-PU foam rigid esekelwe emanzini iveza intuthuko ebalulekile kwezobuchwepheshe bokukhiqiza i-polyurethane foam. Lesi sixazululo esisha senza kube lula ukususa imikhiqizo ye-polyurethane foam emisebe ngendlela ehlanzekile nephumelelayo kuyilapho kugcinwa ukuphepha kwemvelo. I-agent yokukhulula idala isithiyo sezinhlayiyana esincane kakhulu phakathi kobuso besikhunta nezinto ze-foam, okuvimbela ukunamathela ngaphandle kokuphazamisa ubuqotho besakhiwo noma ikhwalithi yendawo ye-foam. Ukwakheka kwayo okusekelwe emanzini kuqinisekisa ukumbozwa okuhle nokusetshenziswa okufanayo, okuholela ekusebenzeni kokukhululwa okuhambisanayo kumajometri ahlukahlukene wesikhunta. Ukwakheka kwamakhemikhali okuyingqayizivele kwalesi sitshalo kusenza sikwazi ukwakha ifilimu ezinzile emazingeni okushisa ajwayelekile okucubungula, okuhlinzeka ngokusebenza okuthembekile ngisho nangaphansi kwezimo zokukhiqiza ezifuna kakhulu. Yakhelwe ngokukhethekile ukusebenza nezinhlelo eziqinile ze-polyurethane foam, inikeza izakhiwo ezinhle kakhulu zokukhulula ngenkathi kunciphisa ukwakheka kwesikhunta nokunciphisa imvamisa yemisebenzi yokuhlanza isikhunta. Lesi sithako sokukhulula sibaluleke kakhulu ekukhiqizeni amapaneli okuhlukanisa, izingxenye zezimoto, nezinto zokwakha lapho ukucacisa okuqondile kobukhulu nokuqedwa kobuso kuyizidingo ezibalulekile. Ukwakheka komkhiqizo okusekelwe emanzini nakho kunomthelela ekuphepheni emsebenzini ngokususa amakhemikhali ahamba kancane avame ukuhlotshaniswa nezinye izinto ezisekelwe ku-solvent.
