Kana iwe uri muindasitiri yekuvaka kana kuronga kuvhara imba, unogona kunge wakasangana neizwi remvura vapor permeability (WVP).Asi chii chaizvo chinonzi WVP?Sei zvakakosha pakusarudza zvinhu zvekudzivirira?
Mvura vapor permeability (WVP) chiyereso chekugona kwechinhu kubvumira kufamba kwemhute yemvura.WVP chinhu chakakosha kutariswa kana zvasvika pakuvharisa sezvo ichikanganisa kuita kwese kweiyo insulation mukuchengetedza nzvimbo yakagadzika uye ine simba remukati memba.
Insulation zvinhu zvine yakaderera WVP zvinogona kudzivirira hunyoro kuwanda mukati memadziro ekuvaka uye matenga.Izvi zvakakosha nekuti hunyoro hwepamusoro hunogona kukonzera kukura kwe mold uye kukuvadzwa kwemaitiro nekufamba kwenguva.Nekune rumwe rutivi, zvinhu zvine WVP yakakwira zvinobvumira hunyoro kuti hupfuure, izvo zvingave zvinobatsira mune mamwe mamiriro ezvinhu panodiwa kudzora mwando.
Saka, ungaziva sei iyo WVP yezvinhu zvekudzivirira?Iyo WVP yechinhu inowanzoyerwa mumagiramu paskweya mita pazuva (g/m²/zuva) uye inogona kuyedzwa uchishandisa nzira dzakamira dzakaita seASTM E96.Miedzo iyi inosanganisira kufumura zvinhu kune inodzorwa humidity mamiriro uye kuyera mwero wekuti mhute yemvura inopfuura nemusampuli kwenguva yakati rebei.
Paunenge uchisarudza zvekudzivirira zvepurojekiti, zvakakosha kufunga nezvemamiriro ekunze uye chivakwa chinodiwa.Semuenzaniso, mumamiriro ekunze anotonhora apo kupisa kunodiwa nguva yakawanda yegore, zvakakosha kusarudza kuvhara neWVP yakaderera kudzivirira kuumbwa kwehunyoro uye kukanganisa kunogona kuitika kune chivakwa chekuvaka.Nekune rimwe divi, munzvimbo dzinopisa uye dzine mwando, zvinhu zvine WVP yakakwira zvinogona kudiwa kuti zviwane utariri hwehunyoro huri nani uye kudzivirira kudzikama mukati memadziro.
Kune akawanda marudzi emidziyo yekudzivirira pamusika, imwe neimwe iine maitiro ayo eWVP.Semuyenzaniso, furo insulation zvinhu zvakaita se polyurethane uye polystyrene kazhinji zvine yakaderera WVP, zvichiita kuti ive yakakodzera kushandiswa munzvimbo dzinotonhora uye dzakanyorova.Cellulose uye fiberglass insulation, kune rumwe rutivi, ine yakakwirira WVP, zvichiita kuti ikwane zvirinani kune inopisa uye ine mwando mamiriro ekunze.
Pamusoro pekutariswa kwemamiriro ekunze, nzvimbo uye kushandiswa kwekudzivirira kunofanirwawo kutariswa.Semuenzaniso, kuvhara mukamuri yepasi kana kukambaira kunogona kuda zvinhu zvine WVP yakaderera kudzivirira hunyoro kubva kumadziro enheyo.Kusiyana neizvi, insulation yedenga inogona kubatsirwa kubva kune zvinhu zvine WVP yakakwira yekutonga mwando uye kuchengetedzwa kubva mukugwinya.
Mukupedzisa, mvura vapor permeability (WVP) chinhu chakakosha chekufunga nezvazvo pakusarudza zvinhu zvekudzivirira zvepurojekiti yekuvaka.Kunzwisisa zvimiro zveWVP zvezvinhu zvakasiyana uye mabatiro azvinoita hunyoro hwekutonga uye kuita kwekuvaka kwese kwakakosha kuve nechokwadi chemukati menzvimbo yakagadzika uye ine simba rinoshanda.Nekufunga nezve yako chaiyo mamiriro ekunze, nzvimbo, uye insulation application, unogona kuita sarudzo ine ruzivo nezve yakanakisa insulation yepurojekiti yako.
