Izincazelo zomkhiqizoI-SWD9001 desalination caisson special polyurea iwu-100% okuqukethwe okuqinile okunuka kamnandi kwe-polyurea elastomer.Ine-anticorrosion ephezulu kanye nokumelana nokuguguleka kwamanzi olwandle futhi inokumelana okuphezulu kwe-cathodic disbonding.Isetshenziswe kabanzi kumaphrojekthi amakhulu wobunjiniyela bokukhipha usawoti emanzini eMelika, e-Australia naseChina yasekhaya.
Izicelo Zomkhiqizo
I-Anticorrosion isivikelo samanzi samathangi okukhipha usawoti emanzini olwandle, i-offshore wharf nezinye izinto zasolwandle.Inokumelana namakhemikhali aphezulu, i-anticorrosion waterproof kanye nokumelana namanzi olwandle, ukunweba impilo yesevisi iminyaka engaphezu kwengu-30.

Inothi lesicelo
Gcoba umfaniswano wengxenye B ngaphambi kokufaka, hlanganisa kahle ama-pigments afakiwe, noma ikhwalithi yomkhiqizo izothinteka.
fafaza i-polyurea ngesikhathi esifanele uma i-substrate surface i-primed.Ukuze uthole indlela yokufaka isicelo kanye nesikhathi sokuphumula se-SWD polyurea speical primer sicela ubheke enye incwajana yezinkampani ze-SWD.
Njalo gcoba i-SWD spray polyurea endaweni encane ngaphambi kokufaka isicelo esikhulu ukuze uhlole isilinganiso sokuxuba, umbala kanye nomphumela wokufutha kulungile.Ukuze uthole ukwaziswa okwengeziwe mayelana nesicelo sicela ubheke ephepheni lakamuva lemiyalelo laimiyalelo yokusetshenziswa kwe-SWD spray polyurea series.
Isikhathi sokukhiqiza umkhiqizo
| Izinga lokushisa le-substrate | Yomile | Ukuhamba ngamandla | qinisa ngokuphelele |
| +10 ℃ | 28s | 45 imiz | 7d |
| +20 ℃ | 20s | 15 imiz | 6d |
| +30 ℃ | 17s | 5 imiz | 5d |
Qaphela: isikhathi sokwelapha siyahlukahluka kuye ngesimo sendawo ikakhulukazi izinga lokushisa kanye nomswakama ohlobene.
I-Shelf Life
* Kusukela ngosuku lomkhiqizi kanye nesimo sephakheji sokuqala esivaliwe:
Ingxenye A: Izinyanga eziyi-10
Ingxenye B: Izinyanga eziyi-10
*Izinga lokushisa lesitoreji:+5-35°C
Ukupakisha: Ingxenye A 210kg/isigubhu, ingxenye B 200kg/isigubhu
Qiniseka ukuthi iphakethe lomkhiqizo livalwe kahle.
* gcina endaweni epholile nengena umoya, gwema ukuchayeka elangeni ngqo.
