Ukwakheka Kwe-Die Kusalokhu Kuyinselele Enkulu Ekukhishweni Kwe-Polymer

Ukwakheka kwe-die kungenye yezinselele ezivame kakhulu zokucubungula ekukhishweni kwe-polymer. Kungakhathaliseki ukuthi kukhiqiza izintambo kanye nama-cable compounds, amafilimu aqhumile, amapayipi, amaphrofayili, noma imikhiqizo yepulasitiki yobunjiniyela, ama-polymer processors angase abhekane nokufakwa kwezinto ezizungezile i-die ngemva kokusebenza okuqhubekayo.

Nakuba ukwakheka kwe-die kungase kubonakale kuyinkinga encane yokulungisa ekuqaleni, ukuqongelela ngokweqile kwezinto kungathinta kancane kancane ukuzinza kokukhipha, ukubukeka komkhiqizo, ukusebenza kahle kokukhiqiza, kanye nezindleko zokukhiqiza. Ukuhlanza njalo kuphazamisa ukukhiqizwa, kwandisa imfucuza yezinto, futhi kunciphisa ukusetshenziswa kwemishini iyonke.

Njengoba isivinini sokukhipha siqhubeka nokukhula kanye nokwakheka kwe-polymer kuba yinkimbinkimbi kakhulu, ukulawula ukwakheka kwe-die kuye kwaba okubaluleke kakhulu kubaprosesa abafuna ukukhiqizwa okuzinzile nokusezingeni eliphezulu.

Lesi sihloko siyachaza:

• Kuyini ukwakheka kwe-die build-up
• Kungani kwenzeka ngesikhathi sokukhishwa kwe-polymer
• Yiziphi izinto ezisengozini kakhulu
• Indlela izimo zokucubungula ezithinta ngayo ukwakheka kwe-die
• Indlela ubuchwepheshe bokwengeza obusekelwe ku-silicone obungasiza ngayo ekuthuthukiseni ukuzinza kwe-extrusion

Kuyini Ukwakheka Kwe-Die?

Ukwakheka kwe-die kubhekisela ekuqongeleleni kancane kancane kwezinsalela ze-polymer, izithasiselo, izigcwalisi, imibala, noma imikhiqizo yokuwohloka ezungeze ukuphuma kwe-die ngesikhathi sokukhishwa okuqhubekayo.

Kuye ngohlelo lwezinto kanye nezimo zokucubungula, amadiphozithi angavela kanje:

• Ukungcola okunsundu noma okumnyama
• Izinsalela ze-polymer ezinamathelayo
• Izinto ezenziwe ngekhabhoni
• Amadiphozithi amhlophe okugcwalisa
• Ukungcola kwendawo ezungeze udebe lwedayi

Ubunzima bokwakheka kwe-die buyahlukahluka ngokuya ngomklamo wokwakheka, imishini yokukhipha, izinga lokushisa lokucubungula, izinga lokucheba, kanye nokuhambisana kwezengezo.

Uma kungalawulwa kahle, lawa ma-depositi angagcina edluliselwe kumkhiqizo okhishwe, okuthinta kokubili ukubukeka kanye nokungaguquguquki kokukhiqiza.

Kungani Kuvela Ukwakheka Kwama-Die?

Ukwakheka kwe-die akuvamile ukubangelwa yinto eyodwa. Kunalokho, ngokuvamile kuvela ekusebenzisaneni kwezakhiwo zezinto, ukwakheka kwesakhiwo, kanye nezimo zokucubungula.

1. Ukungqubuzana Okuphezulu Kwe-Polymer-Metal Interfacial

Ngesikhathi sokukhipha, i-polymer encibilikisiwe ixhumana njalo nezikulufo, imigqomo, kanye nezindawo zokudaya.

Ngaphansi kwezimo eziphakeme zokusika, ukunamathela okuqinile phakathi kokuncibilika kwe-polymer kanye nezindawo zensimbi kungandisa ukuthambekela kokuqongelela izinto.

Izinto ezincibilika kakhulu noma ukuthambisa okunganele ngokuvamile zisengozini enkulu yalesi simo.

2. Ukulayisha Okugcwele Kakhulu

Amakhemikhali e-thermoplastic anamuhla avame ukuqukethe inani elikhulu lama-filler asebenzayo, njenge:

• I-aluminium hydroxide (ATH)
• I-Magnesium hydroxide (MDH)
• I-calcium carbonate
• I-Talk
• I-fiber yengilazi

Nakuba lezi zigcwalisi zithuthukisa ukubambezeleka komlilo noma ukusebenza kahle kwemishini, zingandisa futhi ukuthambekela kokuncibilika kanye nokumelana nokucubungula, okwenza ukuphuma okuzinzile kube nzima kakhulu.

3. Izinga Lokushisa Lokucubungula

Kokubili amazinga okushisa aphezulu kakhulu kanye namazinga okushisa anganele kungabangela ukwakheka kwama-die.

Amazinga okushisa aphezulu angasheshisa ukuwohloka kwe-polymer noma ukuguquguquka okungeziwe, kuyilapho amazinga okushisa aphansi anganciphisa ukugeleza kokuncibilika futhi andise ukucindezeleka kokucheba.

Ngakho-ke, ukugcina ifasitela lokucubungula elifanele kubalulekile ukuze kukhishwe izinto eziqinile.

4. Ukucindezeleka Okukhulu Kokucheba

Ukukhishwa okuphezulu kwe-extrusion kuvame ukuhlotshaniswa nesivinini esiphezulu sesikulufo kanye nokucindezeleka okukhulu kokucheba.

Uma ukucindezeleka ekuphumeni kwedayi kudlula ikhono lokuncibilika kwe-polymer ukugeleza kahle, kungase kube nokungazinzi kobuso, okwandisa amathuba okuqongelela kwezinto ezizungezile idayisi.

Yiziphi Izinhlelo zePolymer Ezithinteka Kakhulu?

Nakuba ukwakheka kwe-die kungenzeka ezintweni eziningi ze-thermoplastic, kuvame ukubonwa ezicelweni ezifana nalezi:

• Ukukhishwa kwefilimu ye-polyethylene (PE)
• Izinhlanganisela ze-polypropylene (PP)
• Izintambo kanye nezintambo ezihlanganiswa ngomthwalo ophezulu we-ATH noma we-MDH
• Amapulasitiki obunjiniyela agcwele kakhulu
• Ukukhishwa kwamapayipi
• Ukukhipha iphrofayili

Uhlelo ngalunye lwezinto luveza izici zokucubungula ezahlukene, ngakho-ke ukukhetha okungeziwe kufanele kusekelwe ekubunjweni okuthile kanye nezidingo zokusetshenziswa.

KanjaniIzithasiselo Ezisekelwe ku-SiliconeUsizo?

Enye indlela ephumelelayo yokunciphisa ukwakheka kwe-die ukuthuthukisa ukugcotshwa kwe-melt nokushintsha ukusebenzisana phakathi kwezindawo zokuncibilika kwe-polymer kanye nezindawo zokucubungula insimbi.

I-silicone masterbatch enesisindo sama-molecule amaningi ivame ukuhlolwa ngale njongo ngoba ingathonya ukuziphatha kokugeleza kokuncibilika ngaphandle kokushintsha ngokuphelele i-polymer matrix.

Izinzuzo ezingaba khona zingafaka:

• Ukungqubuzana kwe-polymer-metal okuncishisiwe
• Ukuqina kokugeleza kokuncibilika okuthuthukisiwe
• I-torque ephansi yokukhipha
• Izindawo zokuhlanza ezihlanzekile ngesikhathi sokukhiqiza okuqhubekayo
• Ukuncipha kwemvamisa yokuhlanza idayisi

Ukusebenza kwangempela kuncike ohlotsheni lwe-polymer, ukwakheka kwesithasiselo, izimo zokucubungula, kanye nezinga lomthamo.

Kungani Kufanele Usebenzise I-Silicone Masterbatch Esikhundleni Sezinto Zokugcoba Ezivamile?

Izithambisi zendabuko zingathuthukisa ukucubungula ngaphansi kwezimo ezithile, kodwa zingase zinganikezi njalo ibhalansi phakathi kokusebenza kahle kokucubungula kanye nokusebenza kwendawo yesikhathi eside.

I-silicone masterbatch njengesithako sepulasitiki kanye ne-polymer modifier ihlanganisa ukuguqulwa kokucubungula kanye nokuthuthukiswa kwendawo, okwenza ifaneleke ezinhlelweni zokusebenza ezidinga kokubili i-extrusion eqinile kanye nekhwalithi yomkhiqizo oqediwe ethuthukisiwe.

Kuye ngendlela eklanywe ngayo, i-silicone masterbatch ingase futhi ibe nomthelela ku:

• Ukushelela kobuso okuthuthukisiwe
• I-coefficient ephansi yokungqubuzana
• Ukumelana okungcono kokuklwebheka nokuklwebheka

Izixazululo ze-SILIKE Silicone Masterbatch Zokuzinza Kwe-Extrusion

I-SILIKE ithuthukisa izixazululo ze-silicone masterbatch ezenzelwe ukusiza abaprosesa be-polymer ukubhekana nezinselele ezivamile zokukhipha kuzo zonke izinhlelo zokusebenza ze-thermoplastic.

Njengoba inolwazi ekuhlanganisweni kwe-silicone-polymer kanye nokuthuthukiswa kohlelo lokusebenza, i-SILIKE isebenza namakhasimende ukuhlola ukuhambisana kokwakheka, ukwenza ngcono izimo zokucubungula, kanye nokuncoma izixazululo ze-silicone masterbatch ngokusekelwe ezidingweni ezithile zokukhiqiza.

Ukusetshenziswa okujwayelekile kwe-silicone masterbatch kufaka phakathi:

•Izakhi zezintambo nekhebula
•Ukukhishwa kwefilimu ye-PE ne-PP
•Ukukhishwa kwamapayipi kanye nephrofayili
•Ipulasitiki yezimoto
• Ipulasitiki yobunjiniyela
• Izinto ze-TPU kanye ne-TPE

Kunconywa ukuhlolwa okuqondene nohlelo lokusebenza ukuze kutholakale ikhambi elifanele kakhulu ohlelweni ngalunye lwe-polymer.

Isiphetho

Ukwakheka kwe-die kuyinto eyinkimbinkimbi yokucubungula ethonywa izici ze-polymer, ukwakheka kokwakheka, izinhlelo zokugcwalisa, kanye nezimo zokukhipha. Nakuba kungekho sixazululo esibanzi, ukuqonda izindlela eziyisisekelo kuvumela abakhiqizi ukuthi bathuthukise amasu okucubungula azinzile futhi asebenzayo.

Eziningi zezinhlelo zokusebenza ze-thermoplastic, i-silicone masterbatch inikeza indlela ephumelelayo yokuthuthukisa ukuziphatha kokuncibilika, ukunciphisa ukungqubuzana kwe-polymer-metal, kanye nokusekela i-extrusion ehlanzekile nehlala njalo.

Ngokusebenzisa intuthuko egxile kuhlelo lokusebenza kanye nokusekelwa kobuchwepheshe, i-SILIKE iyaqhubeka nokusiza abaprosesa be-polymer ukuthi bathuthukise ukusebenza kwe-extrusion futhi bathuthukise ukusebenza kahle kokukhiqiza kuzo zonke izinto ze-thermoplastic.

Xhumana ne-SILIKE ukuze uthole isibuyekezo samahhala sefomula kanye nokuthola i-Technical Data Sheet (TDS) yeI-silicone masterbatch yochungechunge lwe-SILIKE LYSI(izithasiselo ze-polymer ezisekelwe ku-siloxane). Ithimba lethu lochwepheshe likulungele ukuhlinzeka ngezixazululo ezenziwe ngokwezifiso, izicelo zesampula, kanye nokusekelwa kobuchwepheshe okuphelele ukukusiza unqobe izinselele zokucubungula. ukunciphisa i-Die Build-Up kanye ne-die drool, kanye nokukhulisa ukuncintisana komkhiqizo wakho!
