Chii chinokonzeresa kufambiswa kwemhepo yakakwira yemhute yezvinhu zvekurongedza?

Mwero wekufambisa kwemvura yemvura (WVTR)chiyero chinotapurirwa mhute yemvura mukati mechinhu, chinowanzo ratidzwa sehuwandu hwemhute yemvura inopfuura nepakati pechinhu pachikamu chechikamu mune imwe nguva. Icho chimwe chezviratidzo zvakakosha kuyera kupera kwezvinhu kumhute yemvura, zvichienderana nemuviri uye kemikari zvinhu zvezvinhu, zvakadai sekukora kwezvinhu, porosity, chimiro, tembiricha, humidity uye zvichingodaro.

Kuyera nzira uye minda yekushandisa
Kuyera nzira:
Nzira yekuyeresa kapu: Kutapurirana kunoverengerwa nekuyera mutsauko wehutsi hwemvura pakati pemativi maviri echinhu pane imwe nguva yenguva.
infrared nzira: infrared yekuona mhute yemvura kuburikidza nezvinhu.
Electrolysis: kuyerwa kwekufambiswa kwemhute yemvura ne electrolytic reaction.

Nzvimbo yekushandisa:
Indasitiri yekurongedza : Edza mwero wekutapurirana kwemvura yefirimu repurasitiki, bepa, zvinhu zvinoumbwa uye zvimwe zvekurongedza kuti uongorore kuita kwavo kwekurongedza uye kutsva-kuchengeta maitiro.
Indasitiri yemachira : Edzai kufema kwemachira sembatya, shangu, matende, mabhachi emvura uye ongorora kunyaradza kwavo uye kusapinda mvura.
Indasitiri yezvivakwa zvekuvakisa : Edzai zvimisikidzo zvemvura uye zvinofema zvedenga zvisingapindi mvura, zvekunze madziro ekudzivirira zvinhu, pasi pepasi pemvura zvinhu uye zvimwe zvekuvakisa, uye ongorora hunhu hwazvo husina hunyoro, husina mvura uye hunofema.
Indasitiri yezvokurapa : Edzai kupera kwemhepo kwezvinhu zvekurongedza zvekurapa uye mapfekero ekurapa kuti uongorore kugona kwavo kwemhepo uye kuramba kwemvura kumaronda.
Indasitiri yechikafu : Edzai kupera kwemhepo kwezvinhu zvekurongedza chikafu, ongorora hunyoro hwayo, oxidation uye kutsva-kuchengeta maitiro.

Iyo yakakwirira yemvura vapor transmittanceinoratidza kuti chinhu chine chinovharira chisina kunaka kumhute yemvura . Kufambiswa kwemhute yemvura zvinoreva kuwanda kwemhute yemvura inopfuura nechinhu pachikamu chimwe chete panguva yeyuniti, kazhinji mug/(m²·24h). Inoratidza kugona kwechivhariso chemvura kumhunga pasi peimwe tembiricha uye humidity mamiriro. Lower water vapor transmittance zvinoreva kuti nani kudzivirira mwando uye kudzivirira kwakanyanya kwezviri mukati kubva mukunyorova. ,

Kuiswa kwechikafu:
Iyo mvura vapor transmittance inobata zvakananga hupenyu hwesherufu uye kunaka kwechikafu. High water vapor transmittance inokonzeresa kuoma kwechikafu uye kukanganisa kuravira uye kunaka. Kunyanya kuderera kupinza kunogona kutungamira kune yakakwirira humidity nharaunda, nyore kubereka mabhakitiriya uye mold, zvichikonzera kukanganisa kwekudya.
Mushonga aluminium-plastiki inoumba firimu:
Iyo mhute yemvura permeability yemishonga aluminium-plastiki inoumbwa firimu inokanganiswa nekuumbwa kwezvinhu, ukobvu, yekuwedzera mhando uye zvirimo. Kuwanda kwemusiyano pakati pekunyorova kwemukati nekunze, ndiko kukwira kwemhute yemvura. Kunyanya kunyorova kunogona kutungamira kukuwedzera kwe hygroscopic yemuenzaniso, zvichikanganisa kurongeka kwebvunzo.
