Te pereti pore kua whakatakahia he tarapi kowakawaka
He riterite te toha ki roto i te pourewa i te ahua ahuahanga.Ko te tarapi ka aukati i te rere hau-wai, ka pai ake te rere o te hongere me te rere o te pakitara, me te whakaiti i te heke pehanga.I te wa ano, ka whakarato ano i te waahanga mata nui ake, ka tutuki pai ake te papatipu me te mahi whakawhiti wera.
Ko te pereti pore pore takai kowakawaka he kore noa he porosity teitei, he nui te waahanga mata motuhake, engari ano hoki nga painga o te kaha compressive teitei, te pai o te awangawanga waiariki, me te pāmahana whakahaere teitei.
Awhe tono:
Ko te kowiri tira orifice pereti kowakawaka te nuinga whakamahia i roto i te ahumahi petrochemical (pērā i te hinu masivesivá tukatuka hinu-wai
tarapēke whakawehe, tarapēke coalescer), ahumahi tongi, purenga hau māori, whakarewa, aha atu penei i te matū waro
ahumahi (te whakaora i te benzene masivesivá i roto i te tipu coking) Pourewa, pourewa debenzene), wehenga ethylene styrene, tino parakore
te whakarite hāora, te wehenga o te propylene oxide, te pourewa debutane, te whakaora mai i te cyclohexane, te hautanga penehīni, te hau me te
taputapu para hinu korehau.
Ko te Metal rolled pore plate corrugated packing, e mohiotia ana ko Cannon filler (Cannon Packing), i whakawhanakehia i Ingarangi i te tau 1949, a he maha nga pepa kowiri tira angiangi kua purua ki nga rua iti, engari kaore i tangohia e te whiu te whakarewa kia rongonui ai. ka waiho hei mata taratara.He pai tenei tukanga ki te makuku o te wai i runga i te mata whakakī, kia kore ai e pai ki te whakakii i te waea waea me te makuku mo nga wa maha i mua i te whakamaarama.He pai te tarapi i roto i te taiwhanga he ahua nui te kaha miihini.
Ko te pereti kowakawaka whakakikoruatia te pereti whakakikoruatia. Ko te rereketanga nui i waenga i te tarapi kowakawaka me te pereti kowaowao whakarewa tarapi kowakawaka(he pereti orifice whakarewa ranei) ko te mata o te pereti ehara i te kohao pupuhi, engari he kohao wero, ma te hurihuri i runga i te pereti i hurihia he kohao tino nui o te 0.4-0.5mm te kohao tataramoa iti. Ko te kaha o te wehenga he rite ki te pereti kowhatu kowhatu kowhatu, engari he kaha te kaha o te kaha o te kaha ki te aukati i te pereti kowhatu kowhatu, a he iti te utu, āhua whānui whakamahia.
