Liphaephe tsa PVC ke thepa ea kaho e fumanehang hohle, e nang le lisebelisoa tse fapaneng tse hlokang thepa le boholo bo itseng. Mona ke tlhahlobo e felletseng ea ts'ebetso ea tlhahiso ea lipeipi tsa PVC le maano a ho ntlafatsa:
1. Tokisetso ea Lintho tse tala
PVC resin powder ke thepa e ka sehloohong e tala. Li-additives tse kang li-plasticizers, stabilizers le colorants li kopantsoe le resin ho finyella thepa e lakatsehang phala ea ho qetela. Boima bo nepahetseng le ho kopanya ho netefatsa hore ho etsoa lintho ka mokhoa o tsitsitseng.
2. Ho omisa
Taolo ea mongobo ke ea bohlokoa. Resin ea PVC e omisitsoe ho tlosa mongobo ofe kapa ofe o ka amang ts'ebetso ea extrusion hampe le boleng ba sehlahisoa sa ho qetela.
3. Extrusion
Motsoako o omisitsoeng oa resin oa PVC o kenngoa ka har'a hopper ea extruder. Sekoti se potolohang se chesa 'me se kopanya thepa, se e qobella ka thipa. The die e bopa PVC e qhibilihisitsoeng ho profaele e lakatsehang ea phala.
·Ho ntlafatsa: Khetho e nepahetseng ea extruder e ipapisitseng le bophara ba phaephe e shebiloeng, bokhoni ba tlhahiso, le moralo oa screw ke ea bohlokoa. Ho beha leihlo nako le nako le ho ntlafatsa maemo a ts'ebetso joalo ka mocheso, khatello, le lebelo la sekoti ho netefatsa hore sehlahisoa se sebetsa hantle le boleng bo sa fetoheng ba sehlahisoa.
4. Hauloff le Cooling
The hul-off e hula phala e extruded ho tswa ho die ka lebelo le laoloang. Sistimi e pholisang e tiisa phala ka potlako ha e tsoa lefing. Taolo e nepahetseng ea lebelo la ho hula le ho tsidifala ho netefatsa sebopeho se nepahetseng sa liphaephe, ho nepahala ha sebopeho, 'me ho qoba ho khopama.
·Ho ntlafatsa: Ho bapisa lebelo la ho hula le lebelo la extrusion ho thibela matla a ho hula a ka senyang phala. Ho sebelisa mochine o pholileng o hlokometsoeng hantle o nang le mokhoa o nepahetseng oa ho pholisa (metsi kapa moea) o tiisa ho tiisa ho nepahetseng le ho fokotsa kotsi ea ho se phethahale.
5. Ho Seha le ho Sizing
Pipe e pholileng e khaola ka bolelele bo lakatsehang ho sebelisa lisakha kapa lisebelisoa tse ling tsa ho itšeha. Li-gauge tsa boholo kapa lisebelisoa tsa ho lekanya li etsa bonnete ba hore liphaephe li finyella litekanyo tse boletsoeng.
·Ho ntlafatsa: Ho sebelisa mekhoa ea ho itšeha e ikemetseng ho ka ntlafatsa katleho le ho fokotsa nako ea tlhahiso. Hangata lisebelisoa tsa ho lekanya boholo li tiisa boholo ba liphaephe tse tsitsitseng nakong eohle ea tlhahiso.
6. Bell End Formation (Boikhethelo)
Bakeng sa lits'ebetso tse ling, pheletso e bōpehileng joaloka tšepe e etsoa ntlheng e le 'ngoe kapa ka bobeli ba phala ho thusa ho kopanya ka samente ea solvent kapa mekhoa e meng.
7. Tlhahlobo le Teko
Lipeipi tse entsoeng li lekoa ka matla ho netefatsa hore li kopana le litekanyo tse hlokahalang bakeng sa boholo, tekanyo ea khatello le thepa e 'ngoe e amehang. Mekhoa ea tlhahlobo e sa senyeheng e sebelisoa hangata.
Ntlafatso: Ho kenya ts'ebetsong mokhoa o matla oa ho laola boleng ka mekhoa e nepahetseng ea ho hlahloba ho fokotsa kotsi ea liphaephe tse nang le bokooa tse fihlang ho bareki.
8.Storage le Packaging
Liphaephe tse phethiloeng tsa PVC li bolokoa le ho pakoa ka nepo bakeng sa ts'ireletso nakong ea lipalangoang le ho ts'oaroa setšeng.
Ka ho utloisisa mohato o mong le o mong oa mokhoa oa ho etsa liphaephe tsa PVC le ho kenya ts'ebetsong mekhoa ena ea ho ntlafatsa, bahlahisi ba ka netefatsa boleng bo tsitsitseng ba sehlahisoa, tlhahiso e sebetsang hantle le litšila tse fokotsehileng. Sena se fetolela phaello e eketsehileng le moeli oa tlhōlisano 'marakeng.
Ikakhele ka setotsoana tšebetsong e felletseng ea tlhahiso ea lipeipi tsa PVC. Utloisisa mohato o mong le o mong le mokhoa oa ho ntlafatsa mohala oa hau oa tlhahiso bakeng sa katleho e kholo.
Ikopanye le rona kajenoho ithuta haholoanyane ka hore na re ka u thusa joang ho ntlafatsa ts'ebetso ea hau ea ho etsa lipeipi tsa PVC. Litsebi tsa rona li ka u fa tlhahlobo e felletseng ea ts'ebetso ea hau ea hajoale le ho tseba libaka tseo u lokelang ho li ntlafatsa.
Tse ling tsa litsela tseo re ka thusang ka tsona ke tsena:
- Theha 'mapa o hlakileng oa tšebetsoea mohala oa hau oa ho etsa lipeipi tsa PVC
- Hlalosa menyetla ea ho iketsetsale lintlafatso tsa ts'ebetso
- Phetha mehato ea taolo ea bolengho netefatsa boleng bo tsitsitseng ba sehlahisoa
- Koetlisa basebetsi ba haumabapi le mekhoa e metle ea tlhahiso ea liphaephe tsa PVC
- Thusa ho khetha lisebelisoa tse nepahetsengbakeng sa litlhoko tsa hau tsa tlhahiso
Ka thuso ea rona, o ka fihlela ts'ebetso ea ho etsa lipeipi tsa PVC tse sebetsang hantle le tse nang le phaello.
