Leha lipolasetiki li na le lintho tse ngata tse ntle, ha se mofuta o mong le o mong oa polasetiki o ka bang le thepa eohle e ntle. Baenjiniere ba thepa le baqapi ba liindasteri ba tlameha ho utloisisa thepa ea lipolasetiki tse fapaneng molemong oa ho rala lihlahisoa tse phethahetseng tsa polasetiki. Thepa ea polasetiki, e ka aroloa ka thepa ea motheo ea 'mele, thepa ea mochine, thepa ea mocheso, thepa ea lik'hemik'hale, thepa ea optical le thepa ea motlakase, joalo-joalo. Ke li-plastiki tse nang le matla a babatsehang, ho hanyetsa tšusumetso, ho hanyetsa mocheso, ho thatafala le ho thibela botsofali. Indasteri ea Japane e tla e hlalosa e le "e ka sebelisoa e le likarolo tsa sebopeho le mechine ea lipolasetiki tse sebetsang hantle, tse hanyetsanang le mocheso ka holimo ho 100 ℃, tse sebelisoang haholo indastering".
Ka tlase re tla thathamisa tse ling tse sebelisoang hangatalisebelisoa tsa tlhahlobo:
1.Melt Flow Index(MF):
E sebelisetsoa ho lekanya sekhahla sa phallo ea ho qhibiliha MFR boleng ba lipolasetiki tse fapaneng le li-resin tse maemong a phallo ea viscous. E loketse lipolasetiki tsa boenjiniere tse kang polycarbonate, polyarylsulfone, polasetiki ea fluorine, nylon joalo-joalo ka mocheso o phahameng oa ho qhibiliha. E boetse e loketse polyethylene (PE), polystyrene (PS), polypropylene (PP), ABS resin, polyformaldehyde (POM), polycarbonate (PC) resin le mocheso o mong oa polasetiki o qhibilihisang ke teko e tlaase. Kopana le litekanyetso: ISO 1133,ASTM D1238,GB/T3682
Mokhoa oa teko ke ho tlohella likaroloana tsa polasetiki hore li qhibilihe ka har'a mokelikeli oa polasetiki ka nako e itseng (metsotso e 10), tlas'a mocheso o itseng le khatello (litekanyetso tse fapaneng tsa lisebelisoa tse fapaneng), ebe li phalla ka bophara ba 2.095mm ea palo ea ligrama. (g). Ha boleng bo boholo, bo betere ho sebetsa ha thepa ea polasetiki, 'me ka tsela e fapaneng. Tekanyetso ea tlhahlobo e sebelisoang haholo ke ASTM D 1238. Sesebelisoa sa ho lekanya bakeng sa tekanyetso ena ea teko ke Melt Indexer. Mokhoa o khethehileng oa ts'ebetso ea teko ke: thepa ea polymer (polasetiki) e lokelang ho lekoa e kenngoa ka har'a groove e nyenyane, 'me qetellong ea groove e hokahane le tube e tšesaane, eo bophara ba eona e leng 2.095mm, le bolelele ba eona. tube ke 8 mm. Ka mor'a ho futhumatsa mocheso o itseng, karolo e ka holimo ea thepa e tala e hatelloa ho ea tlaase ke boima bo itseng bo sebelisoang ke piston, 'me boima ba thepa e tala bo lekanngoa ka hare ho metsotso e 10, e leng index ea phallo ea polasetiki. Ka linako tse ling u tla bona MI25g / 10min e emelang, ho bolelang hore ligrama tse 25 tsa polasetiki li fetisitsoe ka metsotso e 10. Boleng ba MI ba li-plastiki tse sebelisoang hangata bo pakeng tsa 1 le 25. E kholoanyane ea MI, e nyenyane ea viscosity ea lihlahisoa tse tala tsa polasetiki le tse nyenyane tsa boima ba molek'hule; ho seng joalo, ho na le viscosity e kholo ea polasetiki le boima ba limolek'hule bo boholo.
2.Mochini oa Teko oa Universal Tensile(UTM)
Mochini oa tlhahlobo ea lisebelisoa tsa Universal (mochini oa tensile): ho leka ho tsitlella, ho tabola, ho kobeha le lisebelisoa tse ling tsa mochini oa thepa ea polasetiki.
E ka aroloa ka lihlopha tse latelang:
1)Matla a tšepe&Elongation:
Matla a ho tiea, a tsejoang hape e le matla a tensile, a bolela boholo ba matla a hlokahalang ho otlolla thepa ea polasetiki ho isa tekanyong e itseng, hangata e hlalosoang ho latela hore na sebaka se le seng sa yuniti ke matla a makae, 'me peresente ea bolelele ba bolelele ke bolelele. Matla a matla Lebelo le tsitsitseng la mohlala hangata ke 5.0 ~ 6.5mm / min. Mokhoa o qaqileng oa tlhahlobo ho latela ASTM D638.
2)Matla a feto-fetohang&Matla a kobehang:
Matla a ho kobeha, a tsejoang hape e le matla a ho feto-fetoha ha maemo, a sebelisoa haholo ho tseba hore na lipolasetiki li hanana le maemo afe. E ka lekoa ho latela mokhoa oa ASTMD790 mme hangata e hlahisoa ho latela hore na sebaka se seng le se seng sa yuniti se na le matla a makae. Lipolasetiki tse akaretsang ho ea ho PVC, resin ea Melamine, resin ea epoxy le matla a ho kobeha a polyester ke tsona tse ntle ka ho fetisisa. Fiberglass e boetse e sebelisoa ho ntlafatsa ho phutha ho hanyetsa ha polasetiki. Ho kobeha elasticity ho bolela khatello ea kelello e kobehang e hlahisoang ka tekanyo ea yuniti ea deformation sebakeng sa rekere ha mohlala o kobehile (mokhoa oa liteko joalo ka matla a ho kobeha). Ka kakaretso, ha ho kobeha elasticity e kholo, ho molemo ho tiea ha thepa ea polasetiki.
3)Matla a hatellang:
Matla a khatello a bolela bokhoni ba polasetiki ho mamella matla a kantle a khatello. Boleng ba teko bo ka khethoa ho latela mokhoa oa ASTMD695. Polyacetal, polyester, acrylic, urethral resin le meramin resin li na le litšobotsi tse ikhethang tabeng ena.
3.Mochini oa tlhahlobo ea phello ea Cantilever/ Sho fana ka maikutlo a tšehetso ea mochini oa tlhahlobo ea beam
E sebelisetsoa ho lekola matla a matla a thepa eo e seng ea tšepe e kang lakane e thata ea polasetiki, phala, thepa e nang le sebōpeho se khethehileng, nylon e matlafalitsoeng, polasetiki e matlafalitsoeng ka khalase, ceramic, thepa ea motlakase e entsoeng ka majoe, joalo-joalo.
Tumellanong le maemo a machaba a ISO180-1992 "phello ea matla a matla a polasetiki - thepa e thata ea cantilever"; Tekanyetso ea naha ea GB/ T1843-1996 "mokhoa oa tlhahlobo ea phello ea polasetiki e thata ea polasetiki", mokhoa oa indasteri oa mechini JB/ T8761-1998 "mochini oa tlhahlobo ea matla a polasetiki".
4.Liteko tsa tikoloho: ho etsisa ho hanyetsa boemo ba leholimo ba thepa.
