Igwe mbara igwe dị elu dị elu maka ngwa nhazi plastik

NanhaiyaSistemụ ịkwa osisi 3D nke mbara ala nwere ike ijikwa ihe juputara nke ukwuu (dịka PP nwere ≥60% calcium carbonate filler na PA nwere ≥40% fiber fiber filler) ma ọ bụ elastomer viscosity dị elu (dịka TPU na TPE), na-ebelata oge plastik site na 30% -50% ma e jiri ya tụnyere ọdịnala.otu-ịghasa usoro.

Ngwa nke sistemụ ịghasa mbara ala na-elekwasị anya nke ukwuu na ihe ndị siri ike ijikwa usoro ọdịnala otu-screw, yana ngwa ndị bụ isi gbadoro ụkwụ na mpaghara atọ:

1. Nhazi plastik dị elu

Ngwaahịa a na-ahụkarị: Calcium carbonate juputara nke ukwuu mkpụrụ ala ala PP (ọdịnaya njupụta 50% -70%), eriri iko kwadoro akụkụ nhazi ụgbọ ala PA (ọdịnaya njupụta 30%-50%).

Uru isi: Idozi nsogbu nke agglomeration filler na ịgba mbọ hụ na ihe eji arụ ọrụ nke ngwaahịa (dịka ọmụmaatụ, mgbagha ike ike ≤5%).

2. Elastomer na nhazi plastik na-agbanwe agbanwe

Ngwaahịa a na-ahụkarị: TPR rọba ihe egwuregwu ụmụaka, TPE automotive sealing ibe, PVC na-agbanwe ọkpọkọ (ọdịnaya plasticizer ≥30%).

Uru Uru: Nhazi obere okpomọkụ na-ebelata mgbanwe nke plasticizer, ebe shea siri ike na-eme ka agbaze elastomer edo edo, na-egbochi "ịkụnye" n'elu ngwaahịa ahụ.

3. Ngwakọta ihe pụrụ iche na granulation

Ngwaahịa a na-ahụkarị: Plastics na-arụ ọrụ na ntụ ntụ ígwè (dịka ọmụmaatụ, ntụ ntụ ọla kọpa PE conductive granules), seramiiki ntụ ntụ na-eme ka plastik sie ike (dịka ọmụmaatụ, granules PC na-eguzogide Al₂O₃).

Uru Uru: Ngwakọta akụkụ atọ na-eme ka a na-ekesa uzuzu otu (dispersion ≥ 90%), na-egbochi ọdịda arụmọrụ ngwaahịa n'ihi agglomeration ntụ ntụ.
