Iyo PVC Inotambanudza Mucheka Inoshanda sei

PVC yakatambanudza jira, chinhu chinoshanda chinoshandiswa zvakanyanya mumatende, awnings, uye machira ekushambadza, inokunda munzvimbo dzakasiyana siyana nekuda kweiyo yakasarudzika sisitimu yekushandisa. Yakagadzirwa zvakanyanya ne polyvinyl chloride (PVC), PVC inobatwa nehunyanzvi hwekugadzirisa maitiro kuti ipe kutatamuka uye kusimba kwakasiyana.

Nheyo yekushanda yePVC yakatambanudzwa jira inotsamira zvakanyanya pakusimba kwayo uye plastiki. Munguva yekugadzira, iyo PVC zvinhu zvinopisa uye zvakatambanudzwa, zvichigadzira yakanyanya elastic fiber chimiro. Ichi chimiro chinobvumira PVC kutambanudza jira kuti elastically deform uye kuramba kutyoka kana pasi pasi masimba ekunze. Kana simba rekunze rabviswa, jira rinokurumidza kudzokera kune chimiro chayo chepakutanga uye rinochengetedza chimiro chayo chepakutanga uye kugadzikana kwedimensional.

PVC yakatambanudza jira zvakare inoratidza yakanakisa mamiriro ekunze uye kuramba kuchembera. Izvi zvinokonzerwa nekugadzikana kwemakemikari ePVC, iyo inopesana nemigumisiro yemirairo yeUV, mhepo, uye mvura. Uyezve, kuwedzerwa kweakakodzera stabilizers uye plasticizers inogona kuwedzera kusimba kwemamiriro ekunze uye hupenyu hwebasa rePVC jira rakatambanudzwa.

Mumashandisirwo anoshanda, kutambanudza kwePVC jira rakatambanudzwa kunoita kuti igadzirise kune dzakasiyana siyana dzakaoma nzvimbo uye mamiriro ekunze. Semuenzaniso, kana uchigadzira tende, PVC yakatambanudza jira inogona kuenderana nenzvimbo, kuve nechokwadi kugadzikana uye chisimbiso chakasimba. Muchikamu cheawning, PVC yakatambanudzwa jira rinovharisa chiedza chezuva uchichengetedza mhepo yakanaka.

Muchidimbu, PVC yakatambanudza jira, nekuda kweiyo yakasarudzika kutambanudza musimboti uye kuita kwakanakisa, inoita basa rakakosha munzvimbo dzakasiyana siyana.
