Firimu repolypropylene rine mativi maviri (BOPP firimu muchidimbu) ipurasitiki yakanaka kwazvo inochinjika uye inochinjika. Firimu repolypropylene rine mativi maviri rine mabhenefiti ekuti rine simba guru remuviri neremuchina, huremu hushoma, harina chepfu, harina hunyoro, harina hunyoro, harina mashandisirwo akawanda uye rinogara kwenguva refu. Zvichienderana nemashandisirwo akasiyana, firimu repolypropylene rine mativi maviri rinogona kukamurwa kuita firimu rekuvhara kupisa, firimu rekuisa label, firimu rematte, firimu remazuva ose uye firimu re capacitor.
Polypropylene chinhu chakakosha chepurasitiki yepolypropylene inonamira kumativi maviri. Polypropylene ipurasitiki yakagadzirwa nethermoplastic ine simba rakanaka. Ine mabhenefiti ekugadzikana kwakanaka, kuramba kupisa kwakanyanya uye kudzivirira magetsi zvakanaka, uye iri kudiwa zvikuru muchikamu chekurongedza. Muna 2021, polypropylene (PP) yenyika yangu ichasvika matani mamiriyoni 29.143, kuwedzera kwegore negore kwe10.2%. Kubatsirwa nekuwanikwa kwakakwana kwezvinhu zvakagadzirwa, indasitiri yemafirimu epolypropylene inonamira kumativi maviri yakawedzera nekukurumidza, uye kubuda kwayo kwakaramba kuchikwira. Sekureva kwedata kubva kuNational Bureau of Statistics, kugadzirwa kwemafirimu epolypropylene inonamira kumativi maviri munyika yangu kuchasvika matani mamiriyoni 4.076 muna 2021, kuwedzera kwegore negore kwe8.7%.
Nzira dzekugadzira firimu re polypropylene rinotarisa biaxial dzinosanganisira nzira yefirimu re tubular uye nzira yefirimu rakatsetseka. Nekuda kwehunhu husina kuenzana uye kushanda zvakanaka kwezvigadzirwa zvinogadzirwa nenzira ye membrane ye tubular, zvakabviswa zvishoma nezvishoma nemabhizinesi makuru. Nzira yefirimu rakatsetseka inogona kupatsanurwa kuita nzira yekutambanudza biaxial panguva imwe chete uye nzira yekutambanudza biaxial stepwise. Maitiro ekutambanudza biaxial nhanho nhanho ndeaya anotevera: zvinhu zvisina kugadzirwa→extrusion→casting→longitudinal stretching→edge trimming→corona treatment→winding→large film roll→aging→slitting→fining product. Parizvino, nzira yekutambanudza biaxial zvishoma nezvishoma inotorwa nemabhizinesi mazhinji nekuda kwekubatsira kwayo kwetekinoroji yakakura, kushanda zvakanaka kwekugadzira, uye kukodzera kugadzirwa kwakawanda.
Firimu repolypropylene rinotariswa neBiaxial rinoshandiswa zvakanyanya muzvinhu zvekurongedza zvakaita sezvipfeko, chikafu, mishonga, kudhinda, fodya nedoro. Parizvino, firimu repolypropylene rinotariswa neBiaxial rakatora nzvimbo yemafirimu ekupaka akadai sepolyethylene (PE), polypropylene (PP), uye polyvinyl chloride (PVC). Nyika yangu ndiyo nyika yechipiri pakukura pasi rose, uye kudiwa kwemapakeji kuri kuramba kuchikura. Zvichienderana nehuwandu kubva kuChina Packaging Federation, mari inowanikwa nemabhizinesi anopfuura saizi yakatarwa muindasitiri yekurongedza yenyika yangu ichasvika mabhiriyoni 1,204.18 eyuan muna 2021, kuwedzera kwegore negore kwe16.4%. Nekukura nekukurumidza kweindasitiri yekurongedza yenyika yangu, firimu repolypropylene rinotariswa neBiaxial richave nemusika wakakura sezvinhu zvakakosha zvekurongedza.
Vaongorori vemaindasitiri vekuXisijie vakati vachibatsirwa nekuwanikwa kwakakwana kwezvinhu zvakagadzirwa uye kukura kwakanyanya kwetekinoroji yekugadzira, mukana wekuvandudza indasitiri yemafirimu epolypropylene yenyika yangu anotarisa biaxial wakakura. Kukura nekukurumidza kweindasitiri yemapurasitiki kuchasimudzira kuwedzera kwemusika wemafirimu epolypropylene anotarisa biaxial munyika yangu. Nekuwedzera kwekushandiswa kwegreen, vatengi vachawedzera kuvandudza zvinodiwa zvemapurasitiki, uye firimu repolypropylene rinochengetedza simba uye risingakuvadzi nharaunda richava chinhu chikuru mumusika.
