Ndeupi musiyano uripo pakati pePU ganda nePVC dehwe?
Nekuvandudzwa kwesainzi uye tekinoroji, tekinoroji yekugadzira uye danho rekuita rematehwe ematehwe akagadziridzwa zvakare zvakanyanya kuvandudzwa mumakore achangopfuura.Asi sevatengiwo zvavo, vanhu vazhinji havazive mutsauko uripo pakati pePVC nePU zvinhu
1. Iyo PU polyurethane coating mumutoro yakakamurwa kuva marudzi maviri: PU white glue coating uye PU sirivha glue coating.Iko kuita kwekutanga kwePU chena glue uye sirivheri glue coating yakafanana neiyo PA yekupotera, asi iyo PU chena glue uye sirivheri glue coating ine kunzwa kuzere, jira racho rakawedzera elastic, uye kukurumidza kuri nani, uye iyo PU sirivheri glue. Coating inogona kumira kumanikidza kwemvura yakakwira, uye iyo PU coating ine mwando permeability, kufefetera, kupfeka kuramba, nezvimwe, asi mutengo wakakwira uye kuramba kwemamiriro ekunze kwakashata.

2. Kuenzaniswa nePU coating, jira rezasi rePVC rakapfava rakapfava uye rakachipa, asi firimu yePVC yekuputira haisi chepfu chete, asiwo nyore kukwegura.Zvinotonyanya kukosha, kunzwa kwePVC kupfekedza hakuna kunaka sekuya kwePU kupfekedza.Iyo layer yakanaka, uye jira richiri rakaoma.Kana yakapiswa nemoto, kunakirwa kwePVC-yakaputirwa micheka yakakura kudarika iyo yePU-yakaputirwa machira.

3. Pamusoro pekusiyana kwekunzwa uye kuravira pakati pePU nePVC machira akafukidzwa mumukwende, pane imwe pfungwa yekuti PU coating inowanzove yedehwe, nepo PVC iri glue.

4. Nzira yekugadzira yePU yeganda yakanyanya kuoma kupfuura yePVC yeganda.Sezvo jira rekutanga rePU iri canvas PU zvinhu zvine simba rakanaka rekusimba, mukuwedzera pakuputirwa pamusoro pechigadziko jira, jira repasi rinogonawo kuverengerwa pakati.Kuvapo kwejira rezasi risingaonekwe kubva kunze.

5. Zvinhu zvemuviri zvePU ganda zviri nani pane zvePVC yeganda, nekudzivirira kushungurudza, kupfava kwakanaka, kusimba kwepamusoro, uye kupindira kwemhepo (pasina PVC).Iyo pateni yePVC yematehwe inogadzirwa nekupisa kudzvanya nesimbi pateni roller.Iyo pateni yePU yematehwe ndeye kushandisa rudzi rwepetani pepa kupisa uye kudzvanya pamusoro peiyo semi-yakapedzwa dehwe kutanga, kumirira kuti itonhore pasi, wozoparadzanisa dehwe rebepa kuti rigadziriswe pamusoro.Mutengo wePU wematehwe unopfuura zvakapetwa kaviri wePVC wematehwe, uye mutengo wePU wematehwe ane zvimwe zvakakosha zvinodiwa wakapetwa ka2-3 kupfuura wePVC dehwe.Kazhinji, pepa repateni rinodiwa kuPU dehwe rinogona kungoshandiswa ka4-5 nguva uye rinoraswa.Hupenyu hwesevhisi hwepateni roller hwakareba, saka mutengo wePU wematehwe wakakwira kupfuura iwo wePVC dehwe.

Nenzira iyi, chero tichinzwisisa hunhu huri pakati pezviviri izvi, zviri nyore kune vasiri-nyanzvi kuti vaone kana mukwende uri PU kana PVC.Inongoda kusiyanisa kubva kune anotevera mapoinzi matatu: kutanga, kunzwa, Pu yakapfava uye elastic, nepo pvc yakaoma uye inonzwa yakaipa kubata.Chechipiri, tarisa chigadziko chechigadziko, chigadziko chepu chinowedzera uye chidimbu chepurasitiki chakaonda, uye chepvc chakaonda.Chechitatu chiri kupisa, kuravira kwepu kunofanira kunge kwakareruka mushure mekupisa.

Zvichienderana nezviri pamusoro, isu tinogona zvakare kutora mhedziso: kutaura, kuita kwePU dehwe kuri nani pane kwePVC yematehwe, uye mhando yePU mikwende iri nani pane iyo yePVC mikwende!
