Sebakeng sa kaho le tlhahiso, polyvinyl chloride (PVC) e hlahile e le thepa ea khetho ka lebaka la ho feto-fetoha ha eona, ho tšoarella, le ho boloka litšenyehelo. PVC extrusion, mokhoa oa ho fetola resin ea PVC hore e be libopeho tse fapaneng le litlaleho, e bapala karolo ea bohlokoa ho theheng indasteri ea kaho. Ho tloha liforeimi tsa lifensetere le liphanele tsa mamati ho ea ho liphaephe le lisebelisoa, li-extrusions tsa PVC li fumaneha hohle meahong ea sejoale-joale. Ho utloisisa ka botlalo ts'ebetso ea PVC ea extrusion, a re ke re hlahlobeng mehato ea bohlokoa e amehang ts'ebetsong ena ea phetoho.
Mohato oa 1: Tokisetso ea Lintho tse tala
Leeto la PVC extrusion le qala ka ho lokisoa ha lisebelisoa tse tala. Resin ea PVC, e leng motsoako oa mantlha, e hlahlojoa ka hloko le ho kopanngoa le li-additives, tse kang stabilizers, plasticizers, le pigments, ho finyella thepa e lakatsehang bakeng sa ts'ebeliso e reriloeng.
Mohato oa 2: Ho kopanya le ho kopanya
Motsoako o kopantsoeng oa resin ea PVC le li-additives li kena ka mokhoa o phethahetseng oa ho kopanya le ho kopanya. Mokhahlelo ona o kenyelletsa ho kuta ho matla ha mochini le ho pepesetsoa mocheso, ho netefatsa kabo e tšoanang ea li-additives le ho theha motsoako oa homogeneous melt.
Mohato oa 3: Degassing
Motsoako oa PVC o entsoeng ka ho qhibilihisoa o kenngoa ts'ebetsong ea ho senya ho tlosa li-bubble tsa moea tse kentsoeng. Li-bubble tsena tsa moea li ka baka ho se phethahale le ho fokolisa sehlahisoa sa ho qetela, kahoo ho felisoa ha tsona ho bohlokoa bakeng sa ho finyella li-extrusions tsa boleng bo phahameng ba PVC.
Mohato oa 4: Sefa
Motsoako oa PVC o senyehileng o fetisoa ka mokhoa oa ho hloekisa ho tlosa litšila kapa litšila tse setseng. Mohato ona oa ho hloekisa o tiisa hore PVC e entsoeng ka ho qhibilihisoa e hloekile ebile ha e na sekoli, e tlatsetsang tlhahiso ea li-extrusions tse se nang sekoli.
Mohato oa 5: Ho bōpa le ho Extrusion
Motsoako oa PVC o hloekisitsoeng o se o loketse sethala sa ho bopa le sa extrusion. PVC e entsoeng ka ho qhibilihisoa e qobelloa ka lefu le entsoeng ka mokhoa o khethehileng, e leng sebopeho sa eona se khethollang boemo ba sehlahisoa sa ho qetela sa extruded. Ts'ebetso ena e kenyelletsa taolo e nepahetseng ea khatello, mocheso, le sekhahla sa phallo ho fihlela li-extrusions tse tsitsitseng le tsa boleng bo holimo.
Mohato oa 6: Ho pholisa le ho tiisa
Setšoantšo sa PVC se fetisitsoeng, se ntse se le boemong ba ho qhibiliha, se tsoa ka har'a sekoti ebe se kena ka kamoreng e pholileng. Ts'ebetso ena ea ho pholisa e tiisa PVC, e e fetola ho tloha mokelikeli o khonang ho fetoha setšoantšo se thata, se bōpehileng. Sekhahla sa ho pholisa se laoloa ka hloko ho thibela ho phunyeha kapa ho sotha ha profil.
Mohato oa 7: Ho khaola le ho phethela
Boemo ba PVC bo pholileng bo khaoloa ka bolelele bo lakatsehang ka lisakha kapa lisebelisoa tse ling tsa ho itšeha. Li-profiles tse sehiloeng li ka 'na tsa e-ba le mekhoa e meng ea ho qetela, e kang ho roala lehlabathe, ho bentša, kapa ho hatisa, ho finyella sephetho le ponahalo e lakatsehang.
Mohato oa 8: Taolo ea Boleng
Ho pholletsa le ts'ebetso ea PVC extrusion, mehato e thata ea taolo ea boleng e kenngoa ts'ebetsong ho netefatsa hore lihlahisoa tsa ho qetela li finyella litlhoko tse boletsoeng. Sena se kenyelletsa licheke tsa boholo, litlhahlobo tsa pono, le tlhahlobo ea mochini ho netefatsa matla, ho hanyetsa tšusumetso, le lisebelisoa tse ling tsa ts'ebetso ea li-extrusions.
Ho ntlafatsa katleho ea tlhahiso ea PVC Extrusion
Ho ntlafatsa katleho ea tlhahiso ho PVC extrusion, nahana ka maano ana:
Ntlafatsa Tokisetso ea Boitsebiso: Etsa bonnete ba ho kopanya hantle, ho kopanya le ho kopanya lihlahisoa tse tala ho finyella boleng bo tsitsitseng le ho fokotsa mekhoa e fapaneng.
Sebelisa Mekhoa e Sebetsang ea ho Degassing le Filtration Systems: Sebelisa mekhoa e sebetsang ea ho senya le ea ho hloekisa ho felisa litšila le li-bubble tsa moea, ho fokotsa likoli le ho ntlafatsa boleng ba sehlahisoa.
Boloka Taolo e Nepahetseng ea Ts'ebetso: Kenya ts'ebetsong taolo e nepahetseng holim'a khatello, mocheso le sekhahla sa phallo nakong ea extrusion ho fihlela boholo le thepa ea sehlahisoa.
Ntlafatsa Ts'ebetso ea ho Pholisa: Ntlafatsa sekhahla sa ho pholisa ho netefatsa ho tiea ka nepo ha profil e kentsoeng ha u ntse u thibela ho phatloha kapa ho soahlamana.
Kenya Ts'ebetsong Mekhoa ea Tlhahiso e Ikemetseng: Nahana ka ho kenyelletsa mekhoa ea tlhahiso e ikemetseng ho ntlafatsa ts'ebetso, ho fokotsa litšenyehelo tsa basebetsi, le ho ntlafatsa ts'ebetso ea lihlahisoa.
Tlhokomelo ea Kamehla le Khalo: Etsa tlhokomelo ea kamehla le ho lekanya lisebelisoa ho netefatsa ts'ebetso e nepahetseng le ho fokotsa nako ea ho theoha.
Amohela Mekhoa e Tsoelang Pele ea Ntlafatso: Tsoela pele ho beha leihlo lits'ebetso tsa tlhahiso, ho tseba libaka tse lokelang ho ntlafatsoa, le ho kenya tšebetsong liphetoho ho ntlafatsa ts'ebetso le boleng ba sehlahisoa.
Qetello
Ts'ebetso ea extrusion ea PVC e kenyelletsa letoto la mehato ea phetoho e fetolang resin e tala ea PVC hore e be mefuta e mengata ea libopeho le liprofaele. Ka ho utloisisa mehato ea bohlokoa e amehang, bahlahisi ba ka ntlafatsa ts'ebetso ea bona ea tlhahiso, ba ntlafatsa ts'ebetso, 'me ba lula ba hlahisa li-extrusions tsa boleng bo holimo tsa PVC tse fihlelang litlhoko tsa indasteri ea kaho.
