Skelim bilong PVC Stretch Fabrik Forming Proses
PVC 'stretch fabric', em i wanpela 'synthetic material' we i gat strongpela 'elastic' na i save stap longpela taim, na planti taim ol i save yusim long ol samting bilong ausait, ol haus sel, ol 'advertising fabric', na ol samting bilong lukautim ol sikman. Pasin bilong wokim prodak i save givim hevi long ol samting bilong prodak na sevis laip bilong en, na dispela i mekim na em i bikpela samting long save gut long 'core process flow'.
Wok bilong wokim PVC 'stretch fabric' i gat 4-pela bikpela step: miksim ol 'raw material', 'extrusion calendering', 'stretching' na 'orientation', na 'post-prosesing. Pastaim, ol i miksim 'polyvinyl chloride' (PVC) resin wantaim ol samting olsem 'plasticizer', 'stabilizer', na 'lubricant' long stretpela mak na ol i tromoi i go long wanpela 'high-speed blender' long kamapim wanpela 'paste' wantaim wanpela 'viscosity'. Taim ol i makim ol 'additives' long dispela taim, dispela i save mekim na ol samting i no inap senis hariap, na ol samting i no inap bagarap long taim bilong ren, na ol i no inap sanap strong long UV.
Bihain dispela miks i go insait long 'extruder', we ol i meltim long bikpela hat (inap olsem 160-180 digri) na rausim long wanpela T-dai i go insait long wanpela pepa. Bihain ol i save 'calender' pepa wantaim ol 'roller' bilong bosim 'thickness' na 'smoothness' bilong en. Ol i mas bosim gut 'calendering' tempereja bilong abrusim bagarap bilong ol samting bikos long hat tumas o hevi insait long bodi we i kamap long 'undercooling'.
Stretsing na orientesen em i as wok we i save givim PVC stretch fabrik wantaim bikpela 'elasticity' bilong en. Ol i save hatim pepa pastaim (planti taim 80-120 digri) pastaim long ol i stretim long wanpela 'axial' o tupela 'axial' long wanpela 'longitudinal' o 'transverse stretching machine'. 'Stretch ratio' i save stap 2-5 taim, na i save stretim ol 'molecular chains' long sait bilong strong, na dispela i save mekim samting i kamap longpela na i stap strong. Sampela ol bikpela prodak i save yusim 'sequential stretching' teknoloji long mekim gutpela 'mechanical balance'.
Long pinis, laplap we ol i stretim i go insait long hat seting na kol. Seting bilong hat i gat sotpela taim bilong bikpela hat (inap olsem 100-130 digri) long strongim molekiul straksa na rausim ol hevi i stap yet. Ol i save mekim kol wantaim win o wara long mekim ol 'dimensional stability' i stap gut. Sampela prodak i nidim tu ol tritmen long pes bilong en, olsem ol 'UV-resistant coating' o ol 'flame retardants', long mekim wok bilong en i kamap gutpela moa.
Wok bilong wokim PVC 'stretch fabric' i nidim strongpela kontrol bilong tempereja, spit, na 'tension parameters'. Ol senis long wanpela step inap long mekim ol samting i no wok gut. Ol nupela teknoloji, olsem kamap bilong 'online monitoring' na 'automated control', i wok long kirapim ol nupela proses i go long gutpela wok na i no bagarapim envairomen, na i givim ol gutpela samting bilong helpim ol wok we i no bagarapim envairomen.
