1. Hunhu hwekuwedzera kusina kunaka kwemafuta ekunze muPVC foam products
Parafini wakisi uyePE wakisi ndiwo anonyanya kushandiswa ekunze anotsvedza muzvigadzirwa zvinopupa.Parafini wakisi iri nyore kudonha, saka PE wakisi inowanzoshandiswa.

Iyo yekunze lubrication haina kukwana, tembiricha munharaunda 4 uye 5 ye extruder haisi nyore kudzora, uye zviri nyore kudarika tembiricha.Pane blister, blisters, yellowing uye rough plate pamusoro peplate pamusoro;Kuwedzera kwekukweshera kupisa kunokonzeresa kuparara kwezvinhu, kutsvuka uye kunama pamusoro pendiro, kutsvedza kwekunze uye kushata kwepurasitiki, zvichikonzera kukwira mukati memukati memugodhi uye kunaya kwemvura pamusoro pechigadzirwa, icho chinowanzoita madziro asina kuenzana. Ukobvu uye kusagadzika shure uye mberi kufamba kwezvimwe zviratidzo pamusoro.
2. Hunhu hwekuwedzera kusina kunaka kwemafuta emukati muPVC foam products
(1) Kusakwana kwekuzora kwemukati, kusaparadzika kwezvinhu zvakanaka, kusaenzana kwepurasitiki, zvakaoma kudzora ukobvu hwezvigadzirwa, gobvu nepakati uye dzakatetepa pamativi ese efoam board, kunamatira kugomba rekuumbwa uye kupisa kwenzvimbo;Kuzora kwemukati kwakawandisa kunoita kuti zvigadzirwa zvine furo zviite brittle uye kudzivirira kupisa kunoderera;Pasi pekuita kweimwe tembiricha uye kunyungudika kunyungudika, inoshandurwa kuita lubrication yekunze, zvichikonzera kusaenzana kwemafuta.

(2) Kusakwana kwemukati nekunze kwekuzora, yakakwira melt viscosity, yakakwira plasticizing torque, yakanyungudika yakanyunguduka madziro adhesion, yero decomposition line pamusoro pezvinhu, kushata kwepamusoro uye kuderedzwa kwemakanika ezvigadzirwa;Iyo yemukati uye yekunze lubrication yakawandisa, iyo plasticizing torque idiki, uye kunyunguduka kwepurasitiki kuri pachena kuti hakuna kukwana.Kunyangwe chigadzirwa chine kunaka kwakanaka, iyo yekumanikidza point adhesion haina kunaka, iyo inokanganisa zvakanyanya ma mechanika echigadzirwa.
(3) Iko kune kuderera kwemukati kwekuzora uye kuwedzera kwekunze kwekuzora, nguva yepurasitiki iri pachena yakareba, torque yeplasticizing yakaderedzwa, chigadzirwa chakaoma kuumba uye chinova brittle;Iko kune kuwedzera kwemukati kwekuzora uye kushoma kwekunze kwekuzora, nguva yepurasitiki yakapfupikiswa zvakanyanya, kune yakakomba madziro anonamira chiitiko, iyo yekudziya kugadzikana nguva inopfupikiswa, uye kune yakaora mitsetse yero pachigadzirwa.

High densityoxidized polyethylene wakisi ndeyepamusoro-inoshanda lubricant mukati nekunze, ichipa yakanakisa plasticizing uye demoulding mhedzisiro.

3. Kuzora kwemukati nekunze hakuna kukwana, iyo melt viscosity yakakura, torque yeplasticizing yakakura, kunyunguduka kwemadziro kunonamira chiitiko kwakakomba, nzvimbo yepasi ine yero muganhu, kutsvedzereka kwepamusoro hakuna kunaka, uye michina yemagetsi. chigadzirwa chakaderera;
Iyo yemukati nekunze lubrication yakawandisa, iyo plasticizing torque idiki, uye kunyunguduka kweplasticization zviri pachena kuti hakuna kukwana.Kunyange zvazvo chigadzirwa chacho chine kunaka kwakanaka, iyo yekumanikidzika yekunamatira haina kunaka, iyo inokanganisa zvakanyanya michina yechigadzirwa;
Nekuzora kwemukati kushoma uye kuwedzera kwekunze kwekuzora, nguva yepurasitiki iri pachena yakareba, torque yeplasticizing inoderedzwa, uye chigadzirwa chakaoma kuumba uye brittle;
Kuwedzera kwemukati mafuta, kushomeka kwekunze kwekuzora, kupfupika kweplasticizing nguva, yakakomba madziro inonamira, ipfupi kupisa kwekushisa nguva, uye kuora mitsetse yero pachigadzirwa.
Qingdao Sainuo Chemical Co., Ltd.Isu tiri vagadziri vePE wax, PP wax, OPE wax, EVA wax, PEMA, EBS, Zinc/Calcium Stearate….Zvigadzirwa zvedu zvakapfuura REACH, ROHS, PAHS, FDA yekuongorora.
Sainuo zorora wakavimbiswa wakisi, gamuchira kubvunza kwako!
