Yazisa:
Uthungelwano olubanzi lweenkqubo zokuhambisa amanzi amdaka angaphantsi komhlaba ludlala indima ebalulekileyo ekugcineni impilo yoluntu kunye nococeko. Phakathi kweentlobo ngeentlobo zeepayipi ezisetyenziswa kwezi nkqubo, iipayipi ezifakwe i-polyurethane ziye zavela njengentsha ephawulekayo. Le bhlog ijolise ekukhanyiseni ukubaluleka, iingenelo kunye nokusetyenziswa kweepayipi ezifakwe i-polyurethane kwicandelo leumjelo wokuhambisa amanzi amdakaumgcas.
Funda ngemibhobho efakwe i-polyurethane:
Umbhobho ofakwe ngepolyurethane, ekwabizwa ngokuba yipayipi efakwe i-PU, yipayipi yentsimbi efakwe i-polyurethane ngenkqubo ekhethekileyo yokuvelisa. Ingaphakathi linokumelana okuhle kakhulu nokuguguleka, ukugqwala kunye neekhemikhali, nto leyo eyenza ukuba ilungele ukuhambisa amanzi amdaka kunye nezinye izinto ezibangela ukugqwala.
Iingenelo zeepayipi ezifakwe i-polyurethane:
1. Ukuqina okuphuculweyo: I-polyurethane lining ithintela ukuguguleka kwemibhobho, yandisa ubomi bemibhobho yakho. Iyamelana nokuguguleka okubangelwa kukuguguleka okukhawulezayo, izinto eziqinileyo kunye nezinye izinto ezidla ngokufumaneka emanzini amdaka.
2. Ukumelana nokugqwala: I-Polyurethane inokumelana okuhle kakhulu neekhemikhali kunye nokumelana nokugqwala. Ukusetyenziswa kwayo njenge-lining yangaphakathi kuqinisekisa ukhuseleko lwexesha elide kwizinto ezigqwala ezihlala zikhona kwimijelo yamanzi amdaka, njenge-hydrogen sulfide.
3. Ukuhamba okutyibilikayo: Umphezulu otyibilikayo kakhulu we-polyurethane lining unciphisa ukungqubana kwaye ukhuthaza ukuhamba okuqhubekekayo nokungaphazanyiswa. Oku kunciphisa ukusetyenziswa kwamandla, ukwehla koxinzelelo kunye namathuba okuqokelelwa kwenkunkuma, ukuqinisekisa ukudluliselwa kwamanzi amdaka ngokufanelekileyo.
Ukusetyenziswa kwemibhobho efakwe nge-polyurethane:
1. Iinkqubo zemijelo yamanzi kamasipala: Iipayipi ezineepolyurethane zisetyenziswa kakhulu kwiinkqubo zemijelo yamanzi kamasipala ukuze zithuthe ngokufanelekileyo imijelo yamanzi amdaka kwaye zinciphise ukugcinwa kwazo. Ukumelana nokugqwala kunye nokukwazi kwazo ukumelana nesantya esiphezulu solwelo kuzenza zilungele ukuhanjiswa kwamanzi amdaka kwiindawo zokuhlala, zorhwebo kunye nezoshishino.
2. Unyango lwenkunkuma yemizi-mveliso: Amanzi amdaka emizi-mveliso adla ngokuba nezinto ezirhabaxa nezirhabaxa, nto leyo ebangela imingeni kwiziseko zophuhliso zemibhobho ezikhoyo. Imibhobho efakwe ngepolyurethane ibonelela ngesisombululo esithembekileyo ngokukhusela ekukhukulisekeni okubangelwa ziinxalenye eziqinileyo kunye neekhemikhali ezirhabaxa.
3. Imisebenzi Yokwemba: Iipayipi ezineepolyurethane zisetyenziswa kakhulu kwizicelo zemigodi ngenxa yokumelana kwazo nokuguguleka kwazo. Ziphatha ngokufanelekileyo ukuthuthwa kodaka, iintsalela kunye nezinye iimveliso ezingaphantsi kwemigodi ngelixa zinciphisa ixesha lokungasebenzi ngenxa yokugcinwa.
4. Ishishini leoyile negesi: Kwicandelo leoyile negesi, imibhobho efakwe i-polyurethane isetyenziswa kwizigaba ezahlukeneyo ezifana nokugrumba, ukwemba kunye nokucocwa. Ibonakalise ukuba iyasebenza ekuphatheni izinto ezirhabaxa, iikhemikhali ezibolayo, kwanolwelo olushushu kakhulu.
Ukuququmbela:
Umbhobho ofakwe ngepolyurethane uguqule ihlabathi leumbhobho odibeneyo, enika iingenelo ezinje ngokuqina, ukumelana nokugqwala kunye neempawu zokugeleza kwamanzi eziphuculweyo. Ukusetyenziswa kwazo kwiinkqubo zogutyulo lwelindle zikamasipala, ukulahla inkunkuma yemizi-mveliso, imisebenzi yemigodi, kunye nomzi-mveliso weoyile negesi kuye kwabonakalisa ukuguquguquka kwazo kunye nokuthembeka kwazo. Njengoko amazwe ezama ukugcina iziseko zolawulo lwenkunkuma ezisebenzayo, ukuhlanganiswa kwemibhobho efakwe kwi-polyurethane kuqinisekisa uzinzo lwexesha elide kunye nokusebenza kakuhle kweendleko.
