Munguva pfupi yapfuura, zvinhu zvakawanda zvitsva zvakaonekwa, kuitira kuti zvinhu zvine mari yakakwirira munguva yakapfuura zvishoma nezvishoma zvakachinja mumutengo, kunyanya mune shangu nemapombi.
?
Chokwadika, zvimwe zvinhu zvinoratidzika kuva zvakanaka. Mushure mekuongorora, unogona kunzwisisa kuti ndezvipi zvimwe zvezvikonzero.
?
Semuenzaniso, zvinhu zviviri zvepvc uye pu, vanhu vazhinji vakagara vasina chokwadi, saka musiyano uripo pakati pepvc uye pu zvinhu?
?
Musiyano pakati pepvc uye pu zvinhu
?
PU dehwe rakanyanya kuomarara kupfuura PVC dehwe mukugadzira maitiro. Nekuti iyo PU base jira ndeye canvas PU zvinhu zvine simba rakanaka rekusimba, kunze kwekunge yakaputirwa pamusoro pemucheka wepamusoro, jira repasi rinogonawo kuverengerwa nepakati kuti riite Kuonekwa hakugone kuona kuvepo kwejira.

1. Zvinhu zvemuviri zvePU ganda zviri nani pane PVC yeganda, inopikisa tortuosity, kupfava, kusimba kwepamusoro, uye kufema (hapana PVC).
?
Iyo pateni yePVC yematehwe inoumbwa nekupisa kudzvanya kwesimbi pateni rollers. Iyo pateni yePU yematehwe inopisa yakadzvanywa pamusoro peganda rakapedzwa nemhando yepepa repateni. Mushure mekumirira kutonhora, pepa rematehwe rinoparadzaniswa uye rinogadziriswa pamusoro.
?
Mutengo wePU unopfuura zvakapetwa kaviri wePVC, uye mutengo wePU wematehwe nezvimwe zvakakosha zvinodiwa wakapetwa ka2-3 kupfuura wePVC dehwe.
?
Kazhinji, pepa repateni rinodiwa kuPU dehwe rinogona kungoraswa mushure me4-5 nguva. Iyo nguva yekushandisa yepateni roller yakareba, saka mutengo wePU wematehwe wakakwira kupfuura iwo wePVC dehwe.
?
2. Nzira yekusiyanisa PU nePVC iri nyore.
?
Kubva kumakona, jira rekutanga rePU rakakora kupfuura PVC. Panewo musiyano mukunzwa. Kunzwa kwePU kwakapfava. PVC inonzwa kuoma.
?
Iwe unogona zvakare kushandisa moto kupisa, kuravira kwePU kwakareruka kupfuura iyo yePVC.
