Ungasarudza sei nzira yakakodzera yegranulation kana zvinhu zvakasiyana zvachinjwa?

Kana maresini akachena "akachinjwa", kazhinji pane shanduko munzira yakakodzera yegranulation.

Semuyenzaniso:

• Kuzadza, kunyanya kuzadza kwakawanda, kunowanzoita kuti LLDPE kana LDPE plastic granulation inogona kuchinjwa kubva pamvura ring granulation kuenda pakupisa kwemhepo. Zvese zvinowedzera kuomarara, uye kuchengetedza simba (chengetedza mushure mekuoma); chimiro chezviyo chinotaridzika zvakanaka uye chinoderedza kurasikirwa kwechisikigo kwehupfu hwemucheto.

• Yakawedzerwa, nekuda kwekuvapo kwegirazi fiber kana carbon fiber, zvekuti imwe resin inotonhodza mweya (high density polyethylene, ABS, nezvimwewo) inoteerera inodzokera kukucheka kwechando kwechinyakare (mvura). "General" uye "engineering" (mapurasitiki) hazvisi zvakasiyana.

• Yakasimba, seTPV bumper material inowanzoshandiswa (PP+EPDM+POE dynamic vulcanization), nekuda kwekupararira kwerabha powder muPP continuous phase, zvichiita kuti mvura ring heat ive inonyanya kufarirwa. Inotaridzika zvakanaka uye ine mutengo wakanaka.

○ Kuburitsa zvinhu zvinoshanduka

(1) Nyaya dzemakemikari dzakabatana (XL-PE) ndiyo sarudzo inonyanya kufarirwa yenzvimbo inotonhorera nemhepo. Munzvimbo dzakawanda dzemidziyo yetambo,twin screw/single screw double step muchina + air cooling hot (kana eccentric hot) inoenderana neSPVC neXLPE magadzirirwo akajairwa ekugadzira.

(2) Mukugadzirwa nekugadzirwa kwepolypropylene ine simba rakanyunguduka (HMS-PP), PP reaction extrusion branched inogona kugamuchira zviri nani mvura inopisa.

Zvimwe zvinhu zvakajairika zvakagadziriswa kana sarudzo yemuenzaniso wekucheka batch

• Zvinhu zvinodzivirira tambo dzeSPVC kana zvinhu zvinoonekwa zvekurapa, zviri nani kuti zvese zvinopisa pamusoro pemhepo. Ndizvo zvakaitawo RPVC, asi zvishoma.

• Polystyrene, zvisinei neHIPS kana GPPS, sarudza bhandi rekukanda (rinotonhodza mvura) ndiyo inonyanya kukosha.

• Zvinhu zvinoshandiswa neABS, vazhinji vanosarudza kudhonza (mvura) kuchekwa kunotonhora (chimiro chezviyo zvakatetepa uye refu ndicho chinonyanya kufarirwa). Vanhu vakaedza kushingaira kunotonhorera nemhepo kana kushingaira kwemhete yemvura zvese hazvina dambudziko, chimiro chezviyo chinotaridzika zvakanakawo (chakanaka). Kana kugona kwekugadzira kwakakura kupfuura 3-4t/h, zvine musoro kuchinja kune muchina wekupisa wepasi pemvura kana muchina webhandi.

• Chishandiso chetambo chakavharwa kana kuti chisina kuvharwa zvakanyanya, sarudzo diki yemhete yemvura, sarudzo yakakura yemvura iri pasi pemvura (inoda).

• Chishandiso chetambo chakabatana neSilane, tambo diki sarudza mhete yemvura, hombe (senge tambo ye96/250) sarudza iri pasi pemvura (inopisa).

• Kugadzirwa kweHFFR (halogen isina utsi hwakawanda) uye granulation, inoenderana nemidziyo yeXLPE, asi magadzirirwo eskuruu yeextruder anochinja.

• Copolymer formaldehyde (POM) mugumo, unogona kusarudza mhete yemvura kana iri pasi pemvura (yakachekwa).

• TPU (thermoplastic polyurethane elastomer), yakawanda iri pasi pemvura inopisa, asi divi rimwe chete rechikamu chekuyera cheextrusion rinofanira kugadziriswa kuti rienderane nekumanikidzwa kwekuvaka.

PET filament master batch, inogona kuchekwa ichitonhora nekudhonzwa (mvura) kana kupondwa nekuchekwa kuchitonhora.

• PPC inozivikanwa yekuderedza kubuda kwemhepo (polypropyl carbonate), inogona kusanganiswa nemhando dzese dze resin yekuora (TPS, PLA, PBAT, PBS, PHBV, PHA, PVA, PCL, PGA) uye granulation.

• Fiber refu yegirazi (LFI-PP, LFI-PA) yakanyudzwa.
• Zvinhu zvinoshandiswa zvakanyanya mufekitori yemafirimu anofema ePE - kusanganisa nekubatanidza granulation;

• Cellulose acetate mixed ester molding plastiki – mixing granulation;

• TPEE (rabha re ester re block copolymer) – granulation yekusanganisa;

• K resin – granulation yezvinhu zvakagadzirwa uye zvakagadziriswa;

• SBS, SIS, SEBS block elastomer granulation kana devolatilization granulation;

• Kubatanidza POE, EPDM yekubatanidza uye chimwe chinhu chinoshanda pakubata – kusanganisa granulation;

• Zvinhu zvekuboorera zvepolyethylene (UHMW-PE) zvine huremu hwakanyanya, zvakaita sekusanganisa granulation;

• Wakisi yePolyethylene (PEW) — kusanganisa, kusanganisa uye kusanganisa granulation;

• Resin yepetroleum (C5 kana C9) — zvinoshandiswa uye granulation yakakosha;

• Kuburitsa nekucheka waya yenylon (PA6+PA12+SiC).
