SPC litepisi ka kakaretso li kenyelletsa sebopeho se nang le mekhahlelo e mengata joalo ka lera la thepa ea motheo, lesela le khabisitsoeng le lera le sa senyeheng.Thepa ea motheo e sebelisa phofo ea lejoe la tlhaho (calcium carbonate powder) le resin ea polymer (polyvinyl chloride) e le lisebelisoa tse tala tse lokelang ho fetisoa ka mokhoa oa ho kopanya mocheso.
SPC stairnose ke sehlahisoa se ntšang thepa ea motheo ea PVC ka extruder e kopantsoeng le lefu le nang le sebopeho sa T, 'me e sebelisa calender ea li-roll tse tharo kapa tse' nè ho arola PVC e sa khoneng ho apara, filimi ea PVC ea mebala le lisebelisoa tsa motheo tsa PVC, le mocheso, laminate le toboketsa sehlahiswa ka nako e le nngwe., Mokhoa ona o bonolo, ho lekana ho phethoa ke mocheso, ha ho hlokahale sekhomaretsi.
Mekhoa ea ts'ebetso ea tlhahiso ea litepisi tsa SPC:
1. Ho fepa: PVC resin powder, calcium powder, plasticizer, stabilizer le lisebelisoa tse ling tse tala li feptjoa ka tekanyo ka tsamaiso ea metering koung ea ho fepa, 'me ho fepa ke ho fepa ka letsoho kapa ka vacuum.
2. Ho kopanya: metering ea othomathiki ho latela karolelano ea lisebelisoa tse tala, lisebelisoa tse tala ka sistimi ea metering li kenya motsoako o phahameng le o tlase oa lebelo → motsoako o phahameng oa ho kopanya o chesang (mocheso o chesang o kopanyang mocheso: 125 °C, mosebetsi ke ho kopanya mefuta eohle ea lisebelisoa ka ho lekana 'me u tlose mongobo ka har'a thepa ) → kenya motsoako o batang (folisa thepa ho thibela ho kopana le ho fifala, mocheso o kopanyang o batang: 55°C.) → kopanya lisebelisoa tse tšoanang ka ho pholisa.
3. Extrusion molding: Romella lintho tse tala tse tsoakiloeng ka har'a extruder, 'me u sebelise mocheso oa eona o phahameng le boemo ba khatello e phahameng ho feta ka har'a hlobo ea substrate.Ts'ebetso ea extrusion e nka metsotso e ka bang 2, mocheso o ka bang 180-220 ° C, 'me ho sebelisoa oli ea mocheso.Sesebelisoa sea chesa.
4. Sekoahelo sa filimi le calendering: Letlapa le ka tlaase la PVC filimi e kenngoa ka foromo e kopantsoeng e nang le li-calenders tse 'nè kapa tse hlano, lesela le sa khoneng ho apara le filimi ea mebala ea PVC.E amohela ho futhumatsa nako e le 'ngoe, lamination le embossing.Mokhoa ona o bonolo ebile o bonolo ho o beha.E phetheloa ka mocheso, ho sebelisoa selaoli sa mocheso oa ho tsamaisa mocheso oa oli, ho sebelisoa oli ea ho fetisa mocheso e le mokhoa oa ho fetisa mocheso ho boloka mocheso o chesang oa 140 ° C.
5. Ho khaola le ho fokotsa: ho khaola ka mochine oa ho itšeha moleng oa kopano.
6. UV rolara barbotage: Roller jase UV pente e thehiloeng metsi holim'a lejoe-polasetiki mokatong, mocheso le pheko ho fumana SPC lejoe-polasetiki mokatong semi-finished sehlahiswa, UV rolara mocheso: 80-120 ° C;mocheso o pholileng: 10°C
4. Ho petsola le ho petla + ho paka: ho petsola → ho petla, ho poma, ho khahleha → ho hlahloba → ho paka.
