N'ihe gbasara otu, PVC enyemaka nhazi ACR nwere ike kewaa ụzọ atọ:

1. Nhazi ihe enyemaka na-akwalite plasticization: Ụdị enyemaka nhazi a na-ejikarị eme ihe na ngwaahịa PVC siri ike. Isi ọrụ ya bụ ịkwalite plasticization, melite rheological Njirimara nke gbazee ma melite mgbasa nke ihe mgbakwunye ndị ọzọ, ma melite àgwà nke ngwaahịa ahụ.

Kwesịrị ekwesị maka ọtụtụ ngwaahịa PVC dị ka profaịlụ, ọkpọkọ, efere ( mpịakọta), wdg, usoro ntinye aka bụ 1-2phr.

2. Foaming regulator: N'ihi na ya elu molekụla arọ, PVC ụfụfụ regulator nwere ike dịkwuo agbaze ike nke PVC ihe, si otú n'ụzọ dị irè wrapping gas ụfụfụ na-akpụ a edo ebuanu Ọdịdị iji gbochie gas si na-agbanahụ. Onye na-ahụ maka ịfụfụ PVC na-abakwa uru maka ịgbasa ihe mgbakwunye ndị ọzọ gụnyere ihe na-afụ ụfụfụ, na-eme ka ogo ngwaahịa dị elu ma na-abawanye gloss.

3. Enyemaka nhazi mmanye nke mpụga: Ọ nwere otu ihe ahụ dị mma nke na-ewepụ ihe ndị dị na ya dị ka oxidized polyethylene wax. Ihe dị iche bụ na ọ nwere ezigbo ndakọrịta na PVC. Ruo n'ókè ụfọdụ, ọ nwekwara ike ịbawanye arụmọrụ plasticizing nhazi ma melite agbaze. Njirimara Rheological, na mgbasawanye ọpụpụ na-anọgide na-agbanweghị n'oge nhazi extrusion, anaghị agbanwe ihe ndị na-emepụta ihe na-ekpo ọkụ, ma na-egbochi mmetụta haze nke mmiri ozuzo na-eme ka mmiri na-egbuke egbuke na-emepụta.

Ọ dabara maka usoro ma ọ bụ akụrụngwa nwere ihe nhazi dị elu, ọkachasị mpempe akwụkwọ transperent, profaịlụ ụfụfụ, mbadamba ụfụfụ na plastik osisi foamed, wdg. Reference doses 0.5-2phr.

Kpọmkwem na usoro na ngwaahịa, agbaze agbaze nwere ike imeziwanye n'oge calendering, na-ekwe ka ihe fọdụrụnụ na-atụgharị nke ọma n'etiti abụọ rollers; enwere ike imeziwanye àgwà ahụ pụtara ìhè n'oge extrusion ọkpọkọ, na-ewepụ ihe omume "akpụkpọ anụ shark", ma na-amụba ọnụ ọgụgụ extrusion; N'oge extrusion transperent, ọnụ ọgụgụ nke "anya azụ" na ngwaahịa nwere ike belata nke ukwuu; n'oge ịkpụzi injection, mgbaze na-agbaze na-abawanye, si otú ahụ na-ebelata olu ntụtụ, na-ebelata ihe omume "ahịrị ọcha", na-amụba gloss elu, na ịkwalite ike ịgbado ọkụ. Ọ bụrụ na etinyere mmanu mmanu Ihe enyemaka nhazi nwere ike imeziwanye arụmọrụ nbibi, mee ka usoro ịgba ntụtụ dị ngwa ma mụbaa mmepụta, ma gbochie ihe omume "oge ntoju" nke mwepu nke mpụga kpatara; n'oge ịkpụ ịkpụzi, ha nwere ike melite plasticization, belata fisheye phenomena, melite agbaze elasticity, na-eme The ịkpụzi ọkpụrụkpụ bụ ihe edo.
