Sharkskin (kuputsika kwekunyunguduka) inokanganisa kunaka uye kushanda zvakanaka kwepolymer extrusion. Dzidza zvikonzero zvayo, mhinduro dzechinyakare, uye kuti sei fluorine uye PFAS-free polymer processing aids dziri nzira inochengetedza zvakatipoteredza.

Chii chinonzi sharkskin kana surface melt breakdown panguva yekubuda kwema polymers?

Sharkskin (inozivikanwawo sekuputsika kwemvura inonyunguduka) idambudziko rinoonekwa panguva yekubuda kwepolymer melts, apo extrudate inoita chitarisiko chakaomarara, chine mafungu, kana kuti chakakombama chakafanana neganda reshark, kunyanya mumabasa akaita sekuputira firimu, kuumba extrusion, uye wire coating.

Inoratidzwa ne:

Nzvimbo isina kusimba, isina kusimba, kana kuti ine mitsetse pamusoro pechinhu chinobuda (polymer inonyunguduka painobuda mudivha).

Inotaridzika seganda reshark, ndipo panobva zita racho.

Zvikonzero zveganda reshark mu polymer extrusion

Sharkskin rudzi rwekuputsika kwekunyunguduka, kunokonzerwa nekusagadzikana pamadziro epolymer-die. Kana polymer melt yabuda mudi, inosangana nekuderera kamwe kamwe kwekumanikidzwa uye kuwedzera kukuru kwekukurumidza.

Kana kunyunguduka kwacho kukaramba kwakasimba pamadziro edhie (kumanikidzwa kwakanyanya kwemadziro), jira repamusoro rinotambanudzwa zvakanyanya. Izvi zvinotungamira pakuputika nekutsemuka kwenzvimbo yepolymer inonyunguduka nguva nenguva, izvo zvinogadzira patani yeganda reshark.

Mamiriro Akajairika eSharkskin

Kupisa kwakanyanya kupfuura muganho unokosha (kazhinji ~0.1–0.3 MPa, zvichienderana nepolymer).

Kukurumidza kukuru kwekubuda/kuchekwa kwemuchina.

Mapolymer ane viscosity yakakura kana kuti ane mamorekuru akawanda anonyanya kukanganiswa, zvichiitika kakawanda muPP uye linear polymers (semuenzaniso, LLDPE,mLLDPE) kupfuura mumapolymer ane matavi.

Migumisiro yeVagadziri

Mafirimu, machira, kana mapendi epamusoro asina kunaka.

Kuderedzwa kwehunhu hwemakanika (nekuti zvikanganiso zvinogona kuva zvinhu zvinosimbisa kushushikana).

Matambudziko nekujeka kwemaziso uye runako.

Maitiro Ekugadzirisa Sharkskin uye kupwanyika kwepolymer melt extrudates?

Mhinduro & Miganhu Yekuwedzera kwePolymer Yechinyakare

MaPPA eFluoropolymer ave achishandiswa kubvira kuma1960 kuderedza ganda resharks. Anoshanda nekufamba achienda kunzvimbo inofa panguva yekubuda, kuderedza simba repamusoro uye kubatsira kutsvedza kwepolymer. Kunyange zvazvo zvichishanda, maPPA aya akavakirwa paPFAS, zvichikonzera matambudziko ezvakatipoteredza nezvehutano:

• Kugara kuripo muvhu nemumvura

• Kuunganidzwa kwemakemikari mumuviri uye kukanganiswa kwemasero emudumbu

• Kuongororwa kwemitemo pasi rose

Mhinduro dzeSILIKE SILIMER PFAS-Yemahara dzePPA dzeSILIKE SILIMER, Greener Extrusion

SILIMER Series inosanganisira mhando dzakasiyana dzeZvishandiso zvekugadzirisa polymer zvisina PFAS (PPAS)) yakagadzirirwa zvinodiwa zvemazuva ano zvekugadzira:

• 100% PFAS-isina zvinowedzera

•Mabheti makuru asina fluorine

• MaPPA asina fluorine chaiwo

• Zvimwe zvinhu zvisina PTFE

Mhinduro idzi dzakagadzirirwa kuwedzera kushanda zvakanaka kwekugadzirisa ukuwo dzichibvisa njodzi dzine chekuita nePFAS.

 MaPPA asina SILIKE SILIMER PFAS anoenderana nemhando dzakasiyana dzema polymers uye maitiro ekuwedzera, anovandudza mashandiro mu:

• Mapolyolefin nemaresini epolyolefin akadzokororwa

• Mafirimu anonakidza, evatambi, uye ane nhurikidzwa dzakawanda

• Kuburitswa kwefaibha nemonofilament

•Kuburitsa tambo nepombi

•Mashandisirwo eMasterbatch neCompounding

Ingave ichigadzira mafirimu, mapaipi, tambo, kana mafiber, maSILIMER PPA anobatsira vagadziri kuti vawane kugadziriswa kwakapfava, nzvimbo dziri nani, uye kuvandudzwa kwesimba remagetsi.

Unoziva here kuti ndeipi PPAS-free PPAS inosarudzwa nevagadziri vepolymer?

SILIKE SILIMER 9100- Rubatsiro rwekugadzirisa polymer rusina PFAS rwePolyolefins uye resins dzepolyolefin dzakadzokororwa

SILIKE SILIMER 9200–Fluorine-isina fluorine epurasitiki kugadzira chirungiso chekuwedzera

SILIKE SILIMER 9300- PPAS-isina mutengo inoshanda yePPAS yekuwedzera firimu, pombi, uye waya & tambo

SILIKE SILIMER 9400- Chinowedzera chekugadzirisa chisina fluorine chine kutevedzera mitemo yakawanda

Sei Uchifanira KusarudzaZvishandiso zveSILIKE zvekugadzirisa polymer zvisina PFAS?

Kufanana nezvimwe zvinowedzerwa zvechinyakare zve fluoropolymer, zvinowedzera zvinoshanda zveSILIMER PFAS-Free zvinobvisa fluorine, zvinopa kushanda kwepamusoro-pasina njodzi dzezvakatipoteredza:

• Kunyorovesa Kwakawedzerwa - Kunyorovesa kwemukati/kunze kwakavandudzwa kuti kugadziriswa kuve nyore

• Kukurumidza Kubuda Kwemhepo - Kuburitswa kwepamusoro uye kuunganidzwa kwemvura kushoma

• Nzvimbo Dzisina Mavanga – Bvisa kupwanyika kwakanyauka (sharkskin) uye kuvandudza kunaka kwenzvimbo yacho

• Nguva Yakaderedzwa Yekuzorora - Kuchenesa kwenguva refu, kukanganiswa kwemitsara mipfupi

• Kuchengetedzwa Kwezvakatipoteredza – Hazvina PFAS, zvinoenderana neREACH, EPA, PPWR uye mitemo yekuchengetedzwa kwenyika yose

Kubva pafirimu nefaibha kusvika pakuburitsa waya nepaipi, zvikanganiso zveganda reshark hazvichadi kukanganisa kushanda zvakanaka, mhando, kana kutevedzera mitemo. Nekushandisa zvinhu zvinobatsira pakugadzirisa polymer zvisina SILIKE SILIMER PFAS, vagadziri vanogona kuwana kuburitsa kwakapfava, kugona kukuru, uye kushanda kwenguva refu.

Kana uchitsvaga nzira dzekuita izvi:

• Bvisa sharkskin mu polymer extrusion,

• Shandisa zvinowedzera zve polymer zvisina PFAS zvekuwedzera pombi netambo,

• Isa maPPA anochengetedza firimu nefiber extrusion,

• Shandisa zvinhu zvinobatsira pakugadzirisa polymer zvisina fluorine,

• Kuvandudza kubuda kwe extrusion, kana kuderedza kuungana kwe die uye zvikanganiso zvepamusoro mu polymer extrusion
