Ndeupi musiyano uripo pakati pePU dehwe nePVC dehwe?

Nekuvandudzwa kwesainzi uye tekinoroji, tekinoroji yekugadzira uye nhanho yemaitiro ematehwe ekugadzira akagadziridzwa zvakare zvakanyanya mumakore achangopfuura.Synthetic matehwe ematehwe anowedzera uye anoshandiswa zvakanyanya mukugadzirwa kwemabhegi, uye PVC uye PU mabhegi mune ekugadzira matehwe anofarirwa nevatengi vazhinji!Asi sevatengiwo zvavo, vanhu vazhinji havazive mutsauko uripo pakati pePVC nePU,

1. Iyo PU polyurethane coating mubhegi yakakamurwa kuva PU white glue coating uye PU sirivha glue coating.Iwo ekutanga zvimiro zvePU chena glue uye sirivheri glue coating akafanana neaya ePA coating, asi iyo PU chena glue uye sirivheri glue coating ine yakazara ruoko kunzwa, yakawedzera elastic jira uye nekumhanya kuri nani, uye iyo PU silver glue coating inogona kumira nemvura yakakwirira. kudzvanywa, 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 coating rakatetepa uye rakachipa.Nekudaro, iyo firimu yePVC yekupfekedza haina chepfu chete, asiwo iri nyore kukwegura.Zvinotonyanya kukosha, mubato wePVC coating hauna kunaka senge PU coating, uye jira racho rakaomawo.Kana iwe ukashandisa moto, kuravira kwePVC yekupfekedza jira yakakura kwazvo kupfuura iyo yePU yekupfeka jira.

3. Mukuwedzera kune musiyano pakati pePU nePVC machira akavharidzirwa mumabhegi ari muruoko kunzwa uye kuravira, imwe pfungwa ndeyokuti PU coating inowanzove yeganda, nepo PVC iri guruu.

4. Nzira yekugadzira yePU yeganda yakanyanya kuoma kupfuura yePVC yeganda.Sezvo PU base jira iri canvas PU zvinhu zvine simba rakanaka rekusimba, rinogona kupfekedzwa pamusoro pejira rekutanga uye rinosanganisirwa nepakati, zvichiita kuti zvisakwanise kuona kuvepo kwejira rekutanga.

5. Zvinhu zvemuviri zvePU ganda zviri nani pane zvePVC yeganda, nekudzivirira kwakanaka kushanduka, kupfava, kusimba kwesimba uye kufema kwemhepo (PVC haina).Iyo pateni yePVC yematehwe inopisa yakadzvanywa nesimbi pateni roller.Iyo pateni yePU yematehwe inopisa yakadzvanywa pamusoro peganda rakapedzwa nemhando yepepa repatani.Mushure mekutonhora, ganda remapepa rinoparadzaniswa kuitira kurapwa kwepamusoro.Mutengo wePU wematehwe unopfuura zvakapetwa kaviri wePVC yematehwe, uye mutengo wePU wematehwe ane zvakakosha zvinodiwa wakapetwa ka2-3 kupfuura wePVC dehwe.Kazhinji, pepa rakarongwa rinodiwa PU dehwe rinogona kungoshandiswa 4-5 nguva, uye rinozoraswa.Kutenderera kwekushandisa kwepateni roller kwakareba, saka mutengo wePU wematehwe wakakwira kupfuura iwo wePVC dehwe.

Nenzira iyi, chero tichinzwisisa hunhu pakati pezviviri izvi, zvichave nyore kune vasiri nyanzvi vatengi kuona kana mabhegi ari PU kana PVC, chero isu tichiasiyanisa kubva kune anotevera mapoinzi matatu: chekutanga, kunzwa. yakapfava uye yakapfava, nepo kunzwa kwakashata kana PVC yakaoma.Chechipiri, tarisa jira rezasi.Iro jira repasi rePU rakakora uye iro repurasitiki rakatetepa, nepo iro rePVC rakatetepa.Chechitatu chiri kutsva.Iyo pu inonaka ichave yakareruka mushure mekupisa.

Zvichienderana nezviri pamusoro, isu tinogona zvakare kutora mhedziso: kutaura, kuita kwePU matehwe kuri nani pane kwePVC yematehwe, uye mhando yemabhegi ePU iri nani pane iyo yemabhegi ePVC!
