Kupinda kwemvura inotonhorera chinhu chakakosha chekufunga nezvacho pakusarudza zvinhu zvinodzivirira kushandiswa kwakasiyana-siyana. Pakudzivirira foam yerabha yeNBR/PVC, kunzwisisa kupindira kwayo kwemvura inotonhorera kwakakosha pakuona kushanda kwayo munzvimbo dzakasiyana.
Kudzivirira furo rerubha reNBR/PVC chinhu chinoshandiswa zvakanyanya muHVAC, maindasitiri emotokari nekuvaka nekuda kwehunhu hwayo hwakanaka hwekudzivirira kupisa uye kuchinjika kwayo. Zvisinei, chimwe chezvinhu zvakakosha zvine chekuita nechinhu ichi kupindira kwemvura, kana kugona kwemhepo yemvura kupfuura nepakati pacho.
Kupinda kwemvura muNBR/PVC rabha foam insulation material kunoenderana nekuumbwa kwayo uye chimiro chayo. NBR (acrylonitrile-butadiene raber) nePVC (polyvinyl chloride) zvese zvinhu zvakagadzirwa zvinozivikanwa nekusabatwa nehunyoro. Kana zvikasanganiswa nefoam insulation, zvinoumba chidziviriro chakasimba uye chisingapindi mvura chinodzivirira kupinda kwemvura.
Maumbirwo emuchina wekudzivirira furo rerubha weNBR/PVC rabha anosimudzira kushanda kwawo kusingapindi mvura. Kusiyana nemuchina wekudzivirira furo rerubha weOpen-cell, uyo unogona kupinza nekuchengetedza hunyoro, muchina wekudzivirira furo rerubha weClosed-cell unoumbwa nemasero emhepo akavharwa asingabvumidze utsi hwemvura kupfuura nepakati. Izvi zvinoita kuti muchina wekudzivirira furo rerubha weNBR/PVC urambe uchidzivirira hunyoro, zvichiita kuti uve wakakodzera kushandiswa kana hunyoro huchinetsa.
Pamusoro pezvo, chinodzivirira furo rerubha reNBR/PVC chinowanzo putirwa nechinhu chinodzivirira chinopa hunyoro hwekuwedzera. Chinodzivirira furo chinogona kugadzirwa nealuminium foil, fiberglass, kana zvimwe zvinhu zvinowedzera kusimba kwechinodzivirira furo rerubha kumhepo yemvura. Nekuisa chinodzivirira furo ichi muchinodzivirira furo rerubha reNBR/PVC chinoderedza kupenya kwemvura, zvichiita kuti chikwanise kushandiswa munzvimbo dzine hunyoro hwakawanda kana kushandiswa panze.
Pamusoro pekusanyorova, NBR/PVC rabha furo inodziisa ine mamwe mabhenefiti akadai sekudzivirira moto, kudzivirira kupisa uye kunyudza ruzha. Hunhu uhwu hunoita kuti ive sarudzo inoshanduka-shanduka uye yakavimbika kune akasiyana mashandisirwo, kubva pakudzivirira mhepo mumasisitimu eHVAC kusvika pakudzivirira maburi mumaindasitiri.
Pakufunga nezvekubvumidzwa kwemvura inodziya yeNBR/PVC rabha foam insulation, zvakakosha kufunga nezvezvinodiwa chaizvo zvekushandisa. Semuenzaniso, munzvimbo dzine hunyoro hwakawanda kana kugara uchisangana nehunyoro, zvingave zvakakosha kusarudza insulation yakakora kana kuti inofema zvakanyanya kuti uve nechokwadi chekudzivirirwa kwakakwana kubva kuhunyoro hwemvura.
Muchidimbu, kuputira furo rerabha reNBR/PVC hakuna kuputira kwakawanda nekuda kwechimiro charo, chimiro charo uye pamusoro paro panodzivirira. Izvi zvinoita kuti ive sarudzo yakakodzera yekushandiswa inoda kuramba kupiswa nehutsi hwemvura. Nekunzwisisa kuputira kwehutsi hwemvura hwechinhu ichi chekuputira, mainjiniya, makondirakiti nevanoita sarudzo vanogona kusarudza neruzivo pavanenge vachisarudza zvinhu zvekuputira zvemapurojekiti avo, vachiona kuti zvinoshanda kwenguva refu uye zvinogara kwenguva refu.
