Murazvo-unodzora Mvura Isingapindiki uye Inofema Membrane

Tsanangudzo Pfupi:

Mvura isina mvura uye inofema membrane imhando nyowani yepolymer isina mvura zvinhu. Panyaya yetekinoroji yekugadzira, zvinodiwa zvehunyanzvi zvekudzivirira mvura uye zvinofema membranes zvakakwirira zvakanyanya kupfuura izvo zvezvinhu zvakajairwa zvisingapinde mvura; panguva imwe chete, maererano nehutano, mvura isina mvura uye inofema membranes inewo maitiro ayo mamwe maitiro asina mvura haana. Mvura isingapinde uye inofema membranes iri kusimbisa kusapinda kwemhepo kwezvivakwa. Panguva imwecheteyo yekuomesera kwemvura, iyo yakasarudzika mhute permeability inogona kukurumidza kuburitsa mhute yemvura mukati mechimiro, kuchengetedza mashandiro ekupisa kweiyo envelopu chimiro, uye kunyatsozadzisa chinangwa chekudzikisa kuvaka kwesimba rekushandisa, uku uchidzivirira kubereka mold muchimiro, kudzivirira. kukosha kwepfuma, uye Inogadzirisa zvakakwana dambudziko rehunyoro-uchapupu uye hutano hwekugara. Irwo rudzi rutsva rwezvinhu zvinochengetedza simba zvine hutano uye zvakatipoteredza.

Iyo membrane isingapindi mvura uye inofema inosanganiswa nepamusoro-inoshanda zvinhu, izvo zvinogona kubvumira mwando kupfuura nemahara, asi haugone kupinda zvakare mushure mekunyungudika mumvura. Kuti ive nechokwadi chekuti chivako chaoma uye chakasununguka, uye panguva imwechete kudzivirira mvura yakanyungudutswa kubva pakukuvadza denga nemadziro echivako, uye kukuvadza zvinhu zvemukati.

Iyo murazvo-inodzoreredza mvura uye inofema membrane ine hunhu hwekudzimwa kubva mumoto uye ine imwe mhedzisiro yekudzivirira pakuchengetedza.

Tsanangudzo yemusimboti wekushanda wekudzivirira mvura uye inofema membrane: Ngatitangei tiongorore chikonzero che condensation. Mhepo ine mhute yemvura isina ruvara, iyo inowanzopimwa nehunyoro (RH%). Kukwira kwekushisa kwemhepo, ndiko kuwedzera kwemhute yemvura yairi. Kana tembiricha yadzikira, mhepo haigoni kuva nemhute yemvura yepakutanga. Iyo yakaderera tembiricha yemhepo, hunyoro hunowedzera. Kana hunyoro hwasvika 100%, mhute yemvura inobatana kuita mvura. , Condensation inoitika. Tembiricha panguva iyi inonzi condensation point. Muchivako, chero bedzi mhepo inopisa muchivako ichipisa uye inobata tembiricha yakadzika isina denga uye madziro, condensation ichaitika. Kupisa panguva iyoyo kunonzi condensation point. Muchivako, chero bedzi mhepo inopisa muchivako ichipisa uye inobata denga rekushisa rezasi nemadziro, condensation ichaitika. Kana condensation ikaitika, inenge iri padenga. Kana madonhwe emvura anoumbwa pamusoro pemadziro, uye madonhwe emvura anotorwa nechivakwa, nekudaro achiparadza madziro uye denga remadziro, kana kudonha nekukuvadza zvinhu zviri muchivako, shandisa yakasarudzika mvura uye mhute permeability yemvura isingapinde. uye membrane inofema, kunze kwekuita senge rekudzivirira mvura Mukuwedzera, inogonawo kugadzirisa dambudziko remvura-uchapupu hwevhavha yekudzivirira. Kune rumwe rutivi, mhute yemvura inogona kupfuura uye haizounganidzi muchikamu chekudzivirira; kune rumwe rutivi, condensation kana mvura inoyerera padenga kana madziro ichave yakanyatso kuparadzaniswa kubva kune yekudzivirira zvinhu neiyo isina mvura uye inofema membrane, uye haizopinde muvharo yekudzivirira Kuti iite dziviriro yakazara yeiyo insulation layer, ita shuwa. kushanda kweiyo insulation layer, uye uwane mhedzisiro yekuenderera kwekuchengetedza simba.

Mvura isina mvura uye inofema membrane, inozivikanwawo sepolymer anti-adhesive polyethylene isina mvura uye inofema membrane, imhando nyowani yezvivakwa zvisingapinde mvura uye zvakasvibirira. Inoshandiswa zvakanyanya muChina. Inotengeswa zvakare kuEurope, South America, Russia nedzimwe nyika mumatenga esimbi, zviteshi zvechitima, nezvimwewo. Njanji dzinomhanya-mhanya, madziro emaketeni, uye nzvimbo dzakatenuka zvakashandiswa zvakanyanya, uye mhedzisiro yacho yakasimbiswa neruzhinji rwe. vashandisi.
