Esita le baetsi ba nang le phihlelo ka ho fetisisa ba tobana le mathata a extrusion-empa mokhoa o nepahetseng o ka fetola litaba hore e be ntlafatso.
Plastic extrusion ke ts'ebetso e sebetsang hantle haholo bakeng sa ho hlahisa likarolo tse ts'oanang, empa ha e sireletsehe ho mathata a tekheniki. Litšitiso tse tloaelehileng tsa extrusion tsa polasetiki tse joalo ka ho hlaka holimo, lipudula, ho se tsitse ha dimensional, le ho petsoha ho ka senya boleng ba sehlahisoa le ho eketsa litšila. Ho utloisisa hore na ke eng e bakang mefokolo ena-le mokhoa oa ho e lokisa-ke senotlolo sa ho boloka litekanyetso tse phahameng tsa tlhahiso.
1. Surface Rughness: Ha Finish Falls Short
Sebaka se boreleli hangata se bohlokoa bakeng sa botle le ts'ebetso. Haeba u bona liphetho tse thata kapa tsa matte, e kanna ea ba ka lebaka la mocheso o sa tsitsang oa ho qhibiliha, lisebelisoa tse tala tse silafetseng, kapa moralo o fosahetseng oa lefu. Ho ba mahoashe ka holim'a metsi ho ka 'na ha bakoa ke ho tsidifala ho sa lokelang kapa ka lebaka la ho tsikitlana ho feteletseng.
Tharollo:
Etsa bonnete ba hore libaka tsa mocheso li tsitsitse ho pholletsa le barrel
Sebelisa lisebelisoa tsa boleng bo holimo, tse se nang mongobo
Hloekisa khafetsa 'me u hlahlobe lefi
Ntlafatsa litlhophiso tsa ho pholisa le phallo ea moea
2. Li-bubble: Likhase tse Tletseng, Mathata a Koaletsoeng
Li-bubble kapa li-voids ka har'a lihlahisoa tse extruded li ka fokolisa botšepehi ba sebopeho le ho ama ponahalo. Hangata phoso ena e hlaha ho tloha mongobo ka thepa e tala kapa ho kenngoa ha khase nakong ea ts'ebetso ea extrusion.
Tharollo:
Lisebelisoa tse tala esale pele ho tlosa mongobo
Boloka mocheso o tsitsitseng le o nepahetseng oa ho qhibiliha
Fetola litlhophiso tsa vacuum haeba u sebelisa tanka ea ho sing ea vacuum
Fokotsa lebelo la screw haeba ho kuta ho feteletseng ho kenya moea
3. Ho se tsitse ha Dimensional: Ha Mamello e Fetoha Bothata
Ha lihlahisoa tsa extruded li sa boloke boholo bo ts'oanang, li ka sitisa lits'ebetso tse tlase 'me tsa lebisa ho hanang. Lisosa li kenyelletsa khatello e sa tsitsang, ho bata ho sa tsitsang, kapa phallo e sa tsitsang ea thepa e tala.
Tharollo:
Lekanya mocheso le taolo ea khatello
Etsa li-uniform die lips bakeng sa phallo ea thepa e lekanang
Sebelisa mekhoa ea ho laola botenya bo itekanetseng
Boloka litefiso tse tsitsitseng tsa ho pholisa profaeleng eohle
4. Cracking le Brittleness: Matšoao a Khatello ea Maikutlo le Bofokoli
Mapetso kapa maqhetsoana hangata a hlaha ka lebaka la ho tsukutloa ke mocheso, ho pepesehela ho pholile ho feta tekano, kapa ho se lumellane ha thepa. Mefokolo ena ea polasetiki ea extrusion e ka senya ho tšoarella ha sehlahisoa le ts'ebetso.
Tharollo:
Butle-butle li-extrudates tse pholileng ho qoba khatello ea mocheso
Etsa bonnete ba ho hlophisoa hantle le ho kopanngoa ha li-resin
Fokotsa khatello ea kelello nakong ea ho hula
Lekola tsitsipano ea mohala oa extrusion le ho sebetsana
Ho Thibela Mefokolo ho Qala ka Thepa e Nepahetseng
Le hoja liphetoho tsa ts'ebetso le ho sebetsana le thepa e le tsa bohlokoa, tšebeliso ea lisebelisoa tse phahameng tsa extrusion e bohlokoa ka ho lekana. Li-extruder tse tsoetseng pele tse nang le mocheso o nepahetseng le taolo ea khatello li fokotsa haholo ho hlaha ha mefokolo ea polasetiki ea extrusion. Likarolo tse kang ho shebella nako ea sebele, mekhoa ea ho itlhoekisa ea lefu, le li-module tse sebetsang hantle tsa ho pholile li lumella hore ho be le botsitso bo betere le mehato e fokolang ea mokhanni.
Ntlafatsa Ts'ebetso ea Hao, Ntlafatsa Tlhahiso ea Hau
Ka ho tseba lisosa tsa mathata a extrusion le ho kenya ts'ebetsong litharollo tse lebisitsoeng, bahlahisi ba ka fokotsa nako, ba fokotsa litšila, 'me ba fana ka lihlahisoa tsa boleng bo holimo. Tlhokomelo e thibelang, koetliso e nepahetseng, le ntlafatso ea lisebelisoa ke mehato e potlakileng ts'ebetso e 'ngoe le e 'ngoe ea extrusion e lokelang ho nahanoa.
Qetello: Ho nepahala, Thibelo, Ts'ebetso
Plastic extrusion ke bonono haholo joalo ka mahlale. Litšitiso li ka 'na tsa e-ba tse tloaelehileng, empa li ke ke tsa qojoa. Ka ho ela hloko lintlha le ntlafatso e tsoelang pele, o ka fokotsa litaba tsa tlhahiso haholo. Hore na ke ho ntlafatsa maemo a tšebetso kapa ho tsetela mochining o tsoetseng pele, ho nka mehato e nepahetseng kajeno ho tlisa litholoana tse ntle hosane.
U batla ho ntlafatsa ts'ebetso ea mohala oa hau oa extrusion ka tataiso ea litsebi le litharollo tse tsoetseng pele? IkopanyeJWELLkajeno 'me re u thuse ho fetola katleho ea hau ea tlhahiso.
