Ko nga konganuku taumaha-kore-wai Wairewa maramara Polyester&Slurry
Adhesion pai;he hangai ngota he rite ki te polyester, he pai te piri ki te polyester.Ko te adhesion me te polyester he pai ake i te PVA, te acrylate, te maaka whakarereke me etahi atu slurries.
He pai te wairewa;he ngawari te wairewa i roto i te wai wera i runga ake i te 80 ℃, kaore he ua, kaore he kiri, he pai te hototahi ki te maaka, te PVA, te slurry kiriaku, kaore he rerenga, karekau he stratification.
Te pokey iti me te pumau;ka urutau ki te (te riterite teitei, te pehanga teitei, te iti o te pokey) te tukanga rahi, te kuhu kaha, te ngawari ki te uru pai, te whakakotahitanga o te muka, te piri o te huruhuru.
He pakari te rahi o te kiriata;he pakari, he maeneene, he maramara, he pakaru noa i te wa e wehea ana, he maeneene hoki te miro.He maamaa te whakatuwheratanga o te miro, he pai te whakaheke i te tere o te pakaru o te miro warp me te whakapai ake i te pai o te miro.
Ko te whakakapi i te PVA ka taea te whakaiti i te utu;Ka taea te whakakapi i te PVA ki te 1:2, ka taea te whakaiti i te utu slurry i runga i te kaupapa o te whakarite raranga.
He pai ki te taiao;ka taea te waipiro, te hydrolysis, te whakaheke alkali, te whakaahua me te whakaheke microbial.Ehara i te mea he pai ake te mahi whakaheke i te PVA, engari ko te inenga ko te 1/2 anake o te PVA, ka taea te whakaiti i te utu mo te maimoatanga parakaingaki.He parapara-taiao.

Tātai: I runga i te tikanga o naianei, ka noho tonu te katoa o te rōrahi totoka, ka whakamahia te 1kg wai-wairewa polyester slurry hei whakakapi i te 2kg PVA.Ko te waahanga iti ka taapirihia ki te maaka, ki te maaka whakarerekē ranei, ka taapirihia te nui o te kaihoko hinu me te kaihoko antistatic hei whakarite i te reiti rahinga (ka iti iho te reiti o te rahi).
Te rahinga: hoatu te nui o te wai ki roto i te peere rahi, whakaahuria te ranu, tuatahi kuhua ki roto i te māngaro, katahi ka kuhu ki roto i te wai-wairewa polyester slurry, whakaohokia katoa, katahi ka hiki ake te pāmahana ki runga ake i te 95 ℃, katahi ka whakatuwhera i te riipene hau iti ki te Kohuatia mo te neke atu i te 30 meneti, katahi ka tapirihia te hinu, te kaihoko antistatic, te slurry wai ranei, kohuatia ka uru pai, ka whakamahi i muri i te whakatakoto i te rōrahi me te pokey.
Whakamahia i raro i te aratohu a nga tohunga hangarau.
I roto i te tauira slurry, me karohia te slurry awhina kei roto i nga konganuku bivalent, i nga tai whakarewa taumaha ranei, me te karo i te wai e pakeke rawa ana.Ko te wai me te pakeke rawa atu me whakamaroke i mua i te whakamahi.Kaua e whakamahi i te NaOH hei kaihoko pirau i te wa e whakaranua ana te slurry.Me noho te uara PH o te slurry i waenga i te 6 me te 7.
