Iphampu ye-slurry ingasetshenziswa kabanzi ezimayini, amandla kagesi, i-metallurgy, amalahle, ukuvikelwa kwemvelo kanye nezinye izimboni ukuthutha udaka oluqukethe izinhlayiya eziqinile ezihuquzelayo. Ukuthuthwa okunodaka ezimayini, ukususwa komlotha ophuma emanzini aphehlwa ngamalahle, udaka lwamalahle ezindaweni zokuwasha amalahle esindayo kanye nezokuthutha ezisindayo, ukumbiwa kwamashaneli emifula, nokumbiwa kwemifula. Embonini yamakhemikhali, amanye ama-slurries agqwalayo aqukethe amakristalu nawo angathuthwa. Impilo yesevisi emfushane yepompo ye-slurry yiqiniso elaziwayo. Ukuguga kwepompo ye-slurry kubangelwa ikakhulukazi ukugqwala kwe-slurry kanye nokuguguleka koketshezi.
Ucwaningo oluningi luye lwenziwa esikhathini esidlule mayelana nezingubo zokuvikela ukugqwala. Ekukhiqizeni kwangempela, amapende amaningi kanye nezingubo zokugqoka zisetshenziselwa ukulwa nokubola. Kodwa-ke, mayelana nokugqwala nokuguga, ngenxa yomsebenzi olinganiselwe wocwaningo owenziwe esikhathini esidlule, umsebenzi wokucwaninga wokumboza oklanyelwe ukumelana nokugqwala nokuguga ubuyivelakancane. Kuyiqiniso ukuthi izinto eziningi zokumboza zinekhono elithile lokumelana nokugqwala, kodwa i-corrosion wear corrosion coating yokuzivikela isebenza kangcono ngaphansi kwezimo eziqinile zokugqoka ukugqwala. Lokhu kunamathela kuyinsalela ye-polyurethane engagugi.
Izinzuzo ze-elastomeric polyurethanes kule ndawo zibonakala nakakhulu. Ubude bayo obuphezulu kanye nobubanzi obubanzi bobulukhuni; ukumelana kwayo nokugqoka, i-biocompatibility kanye nokuhambisana kwegazi kuvelele ngokukhethekile. Ngesikhathi esifanayo, iphinde ibe nokumelana nowoyela okuhle kakhulu, ukumelana nomthelela, ukumelana nokushisa okuphansi, ukumelana nemisebe kanye nesisindo, ukufakwa kokushisa, ukwahlukanisa nezinye izakhiwo. I-spray polyurethane inezakhiwo ezinhle kakhulu njengokumelana ne-abrasion, ukumelana namanzi, ukumelana nowoyela, ukumuncwa kokudlidliza nokunciphisa umsindo, amandla aphezulu, nokunamathela okuqinile ensimbi, umsindo ophansi, umphumela omuhle wokuzihlanza, ukuguga okuncishisiwe kwephampu ye-slurry, ukonga amandla futhi isikhathi eside. Impilo yephampu ye-slurry ingathuthukisa ukusebenza kahle kwephampu ye-slurry ngezinga elithile. Le nto ye-polyurethane elastomer cishe iyimpahla engeyona eyensimbi ehlangabezana nezidingo zemayini, futhi ingashintsha ngisho nezinye zezinto zensimbi.
Le nto inokumelana nokuguga okuhle nokumelana nokuguguleka. Okubaluleke kakhulu ukusebenza okuphezulu kwe-adhesive efanayo. Ngemuva kwesikhathi eside somthelela kanye nesenzo semishini, isenayo ukunamathela okuqinile ebusweni be-substrate futhi isetshenziswe ngempumelelo endaweni yokusebenza yepompo ye-slurry. Ithemba lentuthuko libanzi kakhulu.
Lesi sikhumba esimelana nokuguga sinesikhathi esikhulu sokuqina kwe-Shore. Ukusuka eShaw A45 ukuya eShore D60. Ubulukhuni bungalungiswa ngokuvumelana nezimo zokusebenza ezihlukene, okuqukethwe kwamaqembu e-polar kungandiswa, izibopho ze-hydrogen zingasetshenziswa ngokugcwele ukwandisa amandla e-intermolecular, futhi isikhathi sokugqoka esisebenzayo singanwetshwa ngokuphumelelayo. Ukwengeza, lokhu okuqukethwe akukwazi nje ukumelana ngokuphumelelayo nokuguguleka nokugqokwa kwe-cavitation, kodwa futhi kungakwazi ukumelana nokugqwala kwe-asidi eqinile kanye ne-alkali ebangeni le-3-11 pH. Lezi zinto azigcini nje ukuvikela indawo engaphezulu ekugugulekeni kwamanzi, ukugqoka kwe-cavitation, kodwa futhi ivikela izingxenye ezivela ku-acid ne-alkali corrosion. Kuyimpahla yokwelapha yangaphezulu enemisebenzi eminingi. Lolu hlobo lwezinto ezibonakalayo luqinile emhlabeni wonke futhi lusetshenziswa kabanzi emikhakheni yezimboni ehlukahlukene lapho kudingekile ukuhlinzeka ngokuvikela ukugqwala nokuvikela ukugqokwa, futhi luzuze imiphumela emihle. Amaqiniso afakazele ukuthi lolu hlobo lwezinto lunesibopho esiqine kakhulu ne-substrate, futhi impilo yokugqoka ngokuvamile iphakeme izikhathi ezingaphezu kweshumi kunezinto ezijwayelekile zensimbi. Izinzuzo zezomnotho zibaluleke kakhulu.
