Amakuru

Sharkskin (gushwanyagurika kw'ingufu) igira ingaruka ku bwiza n'imikorere ya polymer extrusion. Menya impamvu zayo, ibisubizo gakondo, n'impamvu fluorine na PFAS-free polymer processing aids nka SILIKE SILIMER Polymer Processing Aids ari amahitamo arambye.

Gucika kw'uruhu rw'inyama cyangwa gushonga kw'ubuso bw'ingufu ni iki mu gihe cyo gusohora polymer?

Sharkskin (izwi kandi nka surface melt fracture) ni inenge yo hejuru igaragara mu gihe cyo gusohora polymer melt, aho extrudate ikura isa n'aho imeze nk'uruhu rw'ishaki, cyane cyane mu bikorwa nko gusohora filime, gushushanya extrusion, no gusiga insinga.

Irangwa na:

Ubuso bugoye, butarimo amabara menshi, cyangwa butose ku gice cyo hanze (polymer ishonga iyo isohotse mu gice cyo hejuru).

Isa n'imiterere y'uruhu rw'ifi, ari naho izina ryaturutse.

Impamvu zitera uruhu rw'inyama z'inka mu gusohora polymer

Sharkskin ni ubwoko bw'ivunika ry'ingufu, riterwa no kutagira aho rihurira n'urukuta rwa polymer-die. Iyo ivunika rya polymer rivuye muri die, rigira igabanuka ritunguranye ry'umuvuduko n'ubwiyongere bukabije bw'umuvuduko.

Iyo ishongeshonge rifashe cyane ku rukuta rw'icyuma (ubushyuhe bwinshi bw'urukuta), urwego rw'ubuso rurakomera cyane. Ibi bituma ubuso bw'icyuma gishongeshowe bwa polymer bugenda bucika kandi bukavunika, bigatuma habaho ishusho y'uruhu rw'inyama.

Indwara zisanzwe ku ruhu rw'inyama

Gukata umuvuduko urenze urugero rw'ingenzi (akenshi ~ 0.1–0.3 MPa, bitewe na polimeri).

Umuvuduko wo gusohora / gukata umuvuduko mwinshi.

Polima zifite ubukana bwinshi cyangwa uburemere buhanitse bwa molekile zirakunze kwibasirwa cyane, ziboneka kenshi muri PP na polima zigororotse (urugero, LLDPE,mLLDPE) kuruta muri polimeri zifite amashami.

Ingaruka ku bahanga

Ubuziranenge buke bw'amafirime, impapuro, cyangwa irangi ku buso.

Kugabanuka k'imiterere ya mekanike (kuko inenge zishobora kuba ibintu bigabanya stress).

Ibibazo bijyanye no kugaragara neza kw'izuba n'ubwiza bwaryo.

Nigute wakemura ikibazo cy'uruhu rw'inyama n'imisenyi ya polymer melt extrudates?

Ibisubizo n'imbogamizi ku byongewemo bya polymer gakondo

Fluoropolymer PPAs zakoreshejwe kuva mu myaka ya 1960 kugira ngo zigabanye uruhu rw'inyama. Zikora zimuka zijya ku buso bw'inyama mu gihe cyo gusohora, zikagabanya ingufu z'ubuso kandi zigatuma polymer igwa. Nubwo zigira akamaro, izi PPAs zishingiye kuri PFAS, zitera impungenge ku bidukikije n'ubuzima:

• Ubutaka n'amazi birahoraho

• Kwiyongera kw'umubiri n'ingaruka zishobora guterwa n'imisemburo y'amaraso

• Igenzura ry’amategeko ku isi yose

Izamuka ry'ibikoresho byo gutunganya polimeri bidafite PFAS: Ejo hazaza h'ibisubizo birambye byo gusohora polimeri

Ibisubizo bya PPA bya SILIKE SILIMER PFAS bidafite ubushobozi bwo gusohora ibintu mu buryo bw'ubwenge kandi bushimishije

Uruhererekane rwa SILIMER rukubiyemo ubwoko bwinshi bwaUburyo bwo gutunganya polymer budafite PFAS (PPAS)) byagenewe ibikenewe mu nganda zigezweho:

• Inyongeramusaruro zidafite PFAS 100%

•Masterbatches zidafite fluorine

• PPAs zidafite fluorine

• Inyongeramusaruro zidafite PTFE

Ibi bisubizo byakozwe kugira ngo byongere imikorere myiza mu gutunganya no gukuraho ingaruka ziterwa na PFAS.

 PPA zidafite SILIKE SILIMER PFAS zijyanye n'ubwoko bwinshi bwa polymers n'uburyo bwo gusohora, zinoza uburyo bwo gutunganya muri:

• Polyolefini na resins za polyolefini zisubijwe gukoreshwa

• Filime zigezweho, iz'abakinnyi, n'izifite ibyiciro byinshi

• Gusohora fibre na monofilament

•Gusohora insinga n'imiyoboro

•Porogaramu za Masterbatch na compounding

Byaba ari ugukora filime, imiyoboro, insinga, cyangwa imigozi, SILIMER PPAs bifasha abakora gukora ibintu kugira ngo bakore neza, bakore neza kandi barusheho kunoza imikorere.

Ese uzi PPA idafite PFAS ikundwa n'abakora polymer?

SILIKE SILIMER 9100- Ubufasha bwo gutunganya polimeri budafite PFAS kuri Polyolefins na resins za polyolefins zisubijwe gukoreshwa

SILIKE SILIMER 9200–Inyongeramusaruro ya plastiki idafite fluorine yo gutunganya imvange

SILIKE SILIMER 9300– PPA ihendutse kandi ihendutse ikoreshwa mu gusohora filime, imiyoboro, insinga n'insinga ku giciro gito (PFAS)

SILIKE SILIMER 9400– Inyongeramusaruro idafite fluorine kandi ikurikiza amategeko rusange

….

Impamvu yo GuhitamoUbufasha bwo gutunganya polimeri budafite PFAS bwa SILIKE?

Kimwe n'inyongeramusaruro zisanzwe zishingiye kuri fluoropolymer, inyongeramusaruro zidafite SILIMER PFAS zikuraho fluorine, zigatanga umusaruro mwiza cyane—nta ngaruka mbi ku bidukikije:

• Ubushyuhe bwongerewe – Ubushyuhe bw'imbere/inyuma burushaho kunozwa kugira ngo burusheho gutunganywa neza

• Kongera umuvuduko wo gusohora – Umuvuduko mwinshi utuma habaho ubwiyongere buke bw'ibice

• Ubuso budafite inenge – Kuraho kuvunika kw'uruhu rw'ishaka no kunoza ubwiza bw'ubuso

• Kugabanya igihe cyo gukora isuku – Iminsi myinshi yo gusukura, guhagarika umurongo mugufi

• Umutekano w'ibidukikije – Nta PFAS, ikurikiza amabwiriza ya REACH, EPA, PPWR n'amahame mpuzamahanga agenga ibidukikije

Kuva kuri firime na fibre kugeza ku nsinga n'imiyoboro, inenge z'uruhu rw'ingufu ntizigikeneye kwangiza imikorere, ubuziranenge, cyangwa kubahiriza amategeko. Hamwe n'ibikoresho byo gutunganya polimeri bidafite SILIKE SILIMER PFAS, abakora bashobora kugera ku gusohora neza, umusaruro mwinshi, no gukora ibikorwa birambye.

Niba ushaka uburyo bwo:

• Kuraho uruhu rw'inyama zo mu bwoko bwa sharks mu gusohora polymer,

• Koresha inyongeramusaruro za polymer zidafite PFAS mu gusohora imiyoboro n'insinga,

• Shyiraho PPA zirambye mu gusohora filime na fibre,

• Koresha ibikoresho byo gutunganya polimeri bidafite fluorine,

• Kunoza uburyo bwo gusohora imyanda, cyangwa kugabanya ubwiyongere bw'ibinure n'ubusembwa bw'ubuso mu gusohora imyanda ya polymer

hamagara Amy Wang (amy.wang@silike.cncyangwa gusurawww.siliketech.com to shaka igisubizo cyawe kidafite PFAS cyo gukoresha mu gutunganya imashini cyangwa inyongeramusaruro za polymer zibungabunga ibidukikije.
