Sharkskin (yakanyunguduka fracture) inokanganisa polymer extrusion mhando uye kugona. Dzidza zvinokonzeresa, zvigadziriso zvechinyakare, uye nei fluorine uye PFAS-isina polymer kugadzirisa aids seSILIKE SILIMER Polymer Processing Aids ndiyo inogoneka imwe nzira.

Chii chinonzi sharkskin kana kunyunguduka kwepamusoro panguva yekuburitswa kwemapolymers?

Sharkskin (inozivikanwawo sekuti surface melt fracture) chirema chepamusoro chinocherechedzwa panguva yekunyunguduka kwepolymer inonyungudika, uko iyo extrudate inoburitsa hutsinye, wavy, kana kutsvuka senge magadzirirwo eganda re shark. kunyanya mumatanho senge firimu kuvhuvhuta, extrusion molding, uye waya coating.

Inoratidzwa ne:

Yakakasharara, matte, kana yakatsetseka pamusoro peiyo extrudate (iyo polymer inonyungudika painobuda kufa).

Inotaridzika semagadzirirwo eganda re shark, kunova ndiko kunobva zita.

Zvikonzero zve sharkskin mu polymer extrusion

Sharkskin imhando yekunyunguduka kunyunguduka, kunokonzerwa nekusagadzikana kwepolymer-die wall interface. Kana iyo polymer yakanyungudika ichibuda mukufa, inosangana nekudonha nekukurumidza mukumanikidza uye kuwedzera kukuru kwevelocity.

Kana iyo yakanyunguduka yakanamatira zvakasimba kumadziro efa (high wall shear stress), nzvimbo yepamusoro inotambanudzwa zvakanyanya. Izvi zvinotungamirira ku periodic kuputika uye kubvarura kwepolymer melt surface, iyo inogadzira sharkskin pattern.

Yakajairika Mamiriro ezvinhu eSharkskin

Shear stress pamusoro pemuganho wakakosha (kazhinji ~ 0.1-0.3 MPa, zvichienderana nepolymer).

Yakakwira extrusion kumhanya / shear rate.

Yakakwira-viscosity kana yakakwira-mamorekuru-huremu mapolymers anotapukirwa, anoitika kakawanda muPP uye mutsara mapolymer (semuenzaniso, LLDPE,mLLDPE) kupfuura mumatavi emapolima.

Migumisiro kune Vagadziri

Hunhu husina kunaka hwemafirimu, machira, kana machira.

Yakaderedzwa mechanical properties (nokuti kukanganisa kunogona kuva kushungurudza concentrators).

Matambudziko nekujeka kwemaziso uye aesthetics.

Maitiro ekugadzirisa Sharkskin uye kuputika kwepolymer melt extrudates?

Traditional Polymer Additives Solutions & Limitations

Fluoropolymer PPAs yakashandiswa kubva kuma1960 kuderedza sharkskin. Ivo vanoshanda nekutamira kune inofa pamusoro panguva yeextrusion, kudzikisa pamusoro pesimba uye kufambisa polymer kutsvedza. Ichiri kushanda, aya maPPA ari PFAS-yakavakirwa, achisimudza nharaunda uye hutano zvinonetsa:

• Kushingirira muvhu nemvura

• Bioaccumulation uye inogona kukanganisa endocrine

• Kuongororwa kwemitemo pasi rose

Kusimuka kwePFAS-Yemahara Polymer Processing Aids: Iyo Ramangwana reSustainable Extrusion Solutions.

SILIKE SILIMER PFAS-Yemahara PPA Mhinduro dzeSmarter, Greener Extrusion

Iyo SILIMER Series inosanganisira yakazara huwandu hwePFAS-yemahara polymer kugadzirisa aids (PPAs) yakagadzirirwa zvinodiwa zvemazuva ano zvekugadzira:

• 100% PFAS-yemahara additives

•Fluorine-isina masterbatches

• MaPPA asina fluorine akachena

• PTFE-yemahara additives

Mhinduro idzi dzakagadzirwa kuti dzikwidziridze kushanda zvakanaka uku ichibvisa njodzi dzine chekuita nePFAS.

 SILIKE SILIMER PFAS-yemahara PPAs inoenderana neakasiyana akasiyana mapolymers uye extrusion maitiro, anosimudzira kugadzirisa mu:

• Polyolefins uye recycled polyolefin resins

• Mafirimu akaputika, anokandwa, uye akawanda

• Fiber uye monofilament extrusion

•Cable uye pombi extrusion

•Masterbatch uye kusanganisa maapplication

Kunyangwe kugadzira mafirimu, mapaipi, tambo, kana mafiibha, SILIMER PPAs anobatsira vagadziri kuti vagadzirise zvakapfava, nzvimbo dziri nani, uye nekuvandudza maburitsiro.

Unoziva here kuti ndeipi PFAS-yemahara PPA inofarirwa nevagadziri vepolymer?

Sei SarudzaSILIKE's PFAS-Yemahara Polymer Processing Aids?

Sechinyakare fluoropolymer-based additives, SILIMER PFAS-Yemahara inoshanda additives inobvisa fluorine, inoburitsa mashandiro epamusoro-pasina njodzi yezvakatipoteredza:

• Enhanced Lubricity - Kuvandudzwa kwemafuta emukati / ekunze kwekugadzirisa zviri nyore

• Kuwedzera Extrusion Speed - Yakakwirira throughput ine shoma kufa buildup

• Zvisizvo-Zvisina Kurongeka - Bvisa kunyunguduka kunyunguduka (sharkskin) uye kuvandudza kunaka kwepamusoro

• Yakaderedzwa Downtime - Yakareba yekuchenesa mitsetse, kupfupika kwemutsara kukanganisa

• Kuchengetedzwa Kwezvakatipoteredza - PFAS-isina, inowirirana neREACH, EPA, PPWR uye mitemo yepasi rose

Kubva pafirimu uye faibha kuenda kune waya uye pombi extrusion, hurema hweshark hahuchada kukanganisa kushanda zvakanaka, kunaka, kana kutevedzera. Iine SILIKE SILIMER PFAS-yemahara polymer kugadzirisa aids, vagadziri vanogona kuwana yakapfava extrusion, yakakwirira kugadzirwa, uye inoenderera mashandiro.

Kana iwe uchitsvaga nzira dzeku:

• Bvisa sharkskin mu polymer extrusion,

• Shandisa PFAS-yemahara polymer additives pombi uye tambo extrusion,

• Isa maPPA akasimba emufirimu uye fiber extrusion,

• Shandisa fluorine-isina polymer kugadzirisa aids,

• Kuvandudza extrusion throughput, kana kuderedza kufa kuvaka uye kuremara kwepamusoro mu polymer extrusion
