Sharkskin (kusungunuka kwa fracture) kumakhudza khalidwe la polymer extrusion ndi mphamvu. Phunzirani zomwe zimayambitsa, zothetsera zachikhalidwe, komanso chifukwa chomwe fluorine ndi PFAS-free polima zothandizira polima ngati SILIKE SILIMER Polymer Processing Aids ndiye njira yokhazikika.

Kodi chikopa cha shark kapena kusungunuka kwapamtunda ndi chiyani panthawi yotulutsa ma polima?

Sharkskin (yomwe imadziwikanso kuti surface melt fracture) ndi vuto lapamwamba lomwe limawonedwa panthawi yotulutsa polima, pomwe chotulukacho chimakhala chowoneka bwino, chopindika, kapena chopindika ngati khungu la shaki. makamaka munjira monga kuwomba filimu, kuumba extrusion, ndi zokutira waya.

Amadziwika ndi:

Pamwamba, matte, kapena ozungulira pamwamba pa extrudate (polima amasungunuka pamene akutuluka kufa).

Amawoneka ngati mawonekedwe a khungu la shaki, komwe dzinalo limachokera.

Zifukwa za sharkskin mu polymer extrusion

Sharkskin ndi mtundu wosweka wosungunuka, womwe umachitika chifukwa cha kusakhazikika kwa mawonekedwe a khoma la polymer-die. Pamene polima imasungunuka kuchoka pakufa, imakhala ndi kutsika kwadzidzidzi kwa kuthamanga ndi kuwonjezeka kwakukulu kwa liwiro.

Ngati kusungunula kumamatira mwamphamvu ku khoma lakufa (kupanikizika kwa khoma lapamwamba la kukameta ubweya), pamwamba pake amatambasulidwa kwambiri. Izi zimabweretsa kuphulika kwa nthawi ndi kung'ambika kwa polima kusungunula pamwamba, zomwe zimapanga chitsanzo cha sharkskin.

Zomwe Zimachitika kwa Sharkskin

Kumeta ubweya kupitirira malire ovuta (nthawi zambiri ~ 0.1-0.3 MPa, kutengera polima).

High extrusion liwiro / kukameta ubweya.

Ma polima okhala ndi mamasukidwe apamwamba kwambiri kapena olemera kwambiri amakhala otengeka kwambiri, amapezeka pafupipafupi mu PP ndi ma polima amzere (mwachitsanzo, LLDPE),mLLPE) kuposa ma polima okhala ndi nthambi.

Zotsatira kwa Opanga

Mafilimu, mapepala, kapena zokutira ndi zoipa.

Kuchepetsa mphamvu zamakina (chifukwa zolakwika zimatha kukhala zosokoneza maganizo).

Mavuto ndi kumveka bwino kwa kuwala ndi kukongola.

Momwe Mungathetsere Sharkskin ndi kuwonongeka kwa ma polymer melt extrudates?

Traditional Polymer Additives Solutions & Limitations

Fluoropolymer PPAs akhala akugwiritsidwa ntchito kuyambira 1960s kuchepetsa chikopa cha shark. Amagwira ntchito posamukira kumtunda panthawi ya extrusion, kutsitsa mphamvu yapamtunda ndikuwongolera polima. Ngakhale zili zogwira mtima, ma PPA awa ndi ozikidwa pa PFAS, akukweza zovuta zachilengedwe ndi zaumoyo:

• Kulimbikira m'nthaka ndi madzi

• Kuchuluka kwachilengedwe komanso kusokonezeka kwa endocrine

• Kuyang'anira malamulo padziko lonse lapansi

Kukula kwa PFAS-Free Polymer Processing Aids: Tsogolo la Sustainable Extrusion Solutions

SILIKE SILIMER PFAS-Free PPA Solutions for Smarter, Greener Extrusion

Mndandanda wa SILIMER umaphatikizapo mitundu yambiri yaPFAS-free polima processing aids (PPAs) zopangidwira zopangira zamakono:

• 100% Zowonjezera zopanda PFAS

•Ma masterbatches opanda fluorine

• Ma PPA opanda fluorine

• Zowonjezera zopanda PTFE

Mayankho awa adapangidwa kuti apititse patsogolo kukonza bwino ndikuchotsa zoopsa zomwe zimakhudzidwa ndi PFAS.

 SILIKE SILIMER PFAS-free PPAs imagwirizana ndi ma polima osiyanasiyana ndi njira zotulutsira, kupititsa patsogolo kukonza mu:

• Ma polyolefins ndi ma resin a polyolefin obwezerezedwanso

• Makanema owumbidwa, opangidwa, ndi magulu ambiri

• Fiber ndi monofilament extrusion

•Chingwe ndi chitoliro extrusion

•Masterbatch ndi kuphatikiza ntchito

Kaya akupanga mafilimu, mapaipi, zingwe, kapena ulusi, SILIMER PPAs amathandiza opanga kuti azitha kukonza bwino, malo abwinoko, komanso kutulutsa bwino.

Kodi mukudziwa PPA yopanda PFAS yomwe imakondedwa ndi opanga ma polima?

SILIKE SILIMER 9100- Thandizo la PFAS-lopanda polima polima la Polyolefins ndi resin zobwezerezedwanso za polyolefin

SILIKE SILIMER 9200-Zowonjezera za pulasitiki zopanda fluorine zophatikizira

SILIKE SILIMER 9300- PPA yopanda mtengo wa PFAS ya kanema, chitoliro, ndi waya & kutulutsa chingwe

SILIKE SILIMER 9400- Zowonjezera zopanda Fluorine ndikutsata malamulo ambiri

Chifukwa Chosankha?SILIKE's PFAS-Free Polymer Processing Aids?

Monga zowonjezera zachikhalidwe zochokera ku fluoropolymer, SILIMER PFAS-Zowonjezera zogwira ntchito zaulere zimachotsa fluorine, zimapereka magwiridwe antchito apamwamba-popanda kuwopsa kwa chilengedwe:

• Mafuta Owonjezera - Kupititsa patsogolo mafuta amkati / kunja kuti apangidwe bwino

• Kuwonjezeka kwa Kuthamanga Kwambiri - Kupititsa patsogolo kwapamwamba ndi kuwonjezereka kochepa kwa kufa

• Malo Opanda Chilema - Chotsani ming'alu yosungunuka (chikopa cha shark) ndikuwongolera pamwamba

• Kuchepetsa Nthawi Yopuma - Kuyeretsa kwakutali, kusokoneza kwaufupi

• Environmental Safety – PFAS-free, yogwirizana ndi REACH, EPA, PPWR ndi miyezo yokhazikika padziko lonse lapansi

Kuyambira filimu ndi ulusi mpaka waya ndi chitoliro extrusion, zofooka sharks sikufunikanso kusokoneza bwino, khalidwe, kapena kutsatira. Ndi SILIKE SILIMER PFAS-free polima zothandizira polima, opanga amatha kuchita bwino kwambiri, kutulutsa zambiri, komanso magwiridwe antchito okhazikika.

Ngati mukuyang'ana njira zotsatirazi:

• Chotsani chikopa cha shark mu polymer extrusion,

• Gwiritsani ntchito zowonjezera za PFAS zopanda polima popangira chitoliro ndi chingwe chotulutsa chingwe,

• Ikani ma PPA okhazikika a kanema ndi fiber extrusion,

• Gwiritsani ntchito zida zopangira polima zopanda fluorine,

• Limbikitsani kutulutsa kwa ma extrusion, kapena kuchepetsa kuchuluka kwa kufa ndi zolakwika zapamtunda mu polymer extrusion

kulumikizana ndi Amy Wang (amy.wang@silike.cn) kapena pitaniwww.siliketech.com to pezani yankho lanu laulere la PFAS pamachitidwe owonjezera kapena zowonjezera zokomera polymer extrusion.
