Ukwakha I-Die Kusengumngeni Omkhulu kwi-Polymer Extrusion

Ukwakheka kweedayi ngomnye wemingeni eqhelekileyo yokucubungula kwi-polymer extrusion. Nokuba kukhiqizwa iikhompawundi zentambo kunye neentambo, iifilimu ezivuthuziweyo, iipayipi, iiprofayili, okanye iimveliso zeplastiki zobunjineli, iiprosesa zepolymer zinokufumana iidiphozithi zezinto ezijikeleze idayisi emva kokusebenza okuqhubekayo.

Nangona ukwakheka kwezinto ezifileyo ekuqaleni kunokubonakala ngathi yingxaki encinci yokulungisa, ukuqokelelana kwezinto ezininzi kunokuchaphazela kancinci ukuzinza kokukhupha izinto, ukubonakala kwemveliso, ukusebenza kakuhle kwemveliso, kunye neendleko zokuvelisa. Ukucoca rhoqo kuphazamisa imveliso, kwandisa inkunkuma yezinto, kwaye kunciphisa ukusetyenziswa kwezixhobo ngokubanzi.

Njengoko isantya sokukhupha siqhubeka sisanda kwaye iifomyula zepolymer ziba nzima ngakumbi, ukulawula ukwakheka kwe-die kuye kwabaluleka ngakumbi kubaprosesa abafuna imveliso ezinzileyo nesemgangathweni.

Eli nqaku lichaza oku:

• Yintoni i-die build-up
• Kutheni le nto yenzeka ngexesha lokukhupha i-polymer
• Zeziphi izinto ezichaphazeleka lula
• Indlela iimeko zokucubungula ezichaphazela ngayo ukwakheka kwe-die build-up
• Indlela iteknoloji yokongeza esekwe kwi-silicone enokunceda ngayo ukuphucula uzinzo lwe-extrusion

Yintoni i-Die Built-Up?

Ukwakheka kwe-die-up kubhekisa ekuqokeleleni kancinci kancinci kwee-polymer residues, izongezo, izizalisi, iipigments, okanye iimveliso zokubola ezijikeleze i-die exit ngexesha lokuphuma okuqhubekayo.

Ngokuxhomekeke kwinkqubo yezinto kunye neemeko zokucubungula, iidiphozithi zinokubonakala ngolu hlobo:

• Ungcoliseko olumdaka okanye olumnyama
• Iintsalela zepolymer ezinamathelayo
• Izinto ezenziwe ngekhabhoni
• Iidipozithi ezimhlophe zokugcwalisa
• Ungcoliseko lomphezulu ojikeleze imilebe yomlomo

Ubunzima bokwakheka kwe-die buyahluka ngokuxhomekeke kuyilo lwefomyula, izixhobo zokukhupha, ubushushu bokucubungula, izinga lokucheba, kunye nokuhambelana kwezongezo.

Ukuba azilawulwa kakuhle, ezi depositi zinokudlulela kwimveliso ekhutshiweyo, nto leyo echaphazela imbonakalo kunye nokuhambelana kwemveliso.

Kutheni Kusenzeka Ukwakhana Kwee-Die?

Ukwakheka kwee-die build-up akusoloko kubangelwa yinto enye. Endaweni yoko, kudla ngokubangelwa kukusebenzisana kweempawu zezinto, uyilo lwe-formulation, kunye neemeko zokucubungula.

1. Ukungqubana kwePolymer-Metal okuPhakamileyo

Ngexesha lokukhupha, i-polymer enyibilikisiweyo iqhubeka inxibelelana nezikrufu, umgqomo, kunye nomphezulu wokufa.

Phantsi kweemeko ezibukhali kakhulu, ukunamathelana okuqinileyo phakathi kokunyibilika kwepolymer kunye nomphezulu wesinyithi kunokunyusa ukutyekela kokuqokelelana kwezinto.

Izinto ezinyibilikayo kakhulu okanye ukuthambisa okunganelanga zihlala zichaphazeleka lula yile meko.

2. Ukulayisha okuphezulu kwe-Filler

Iikhompawundi ze-thermoplastic zanamhlanje zihlala ziqulathe inani elikhulu lezinto ezizalisa izinto ezisebenzayo, ezinje ngezi:

• I-aluminium hydroxide (ATH)
• I-Magnesium hydroxide (MDH)
• I-calcium carbonate
• Intetho
• Ifayibha yeglasi

Nangona ezi zigcwalisi ziphucula ukubambezeleka komlilo okanye ukusebenza koomatshini, zinokwandisa ukunyibilika kunye nokumelana nokucubungula, okwenza ukukhupha okuzinzileyo kube nzima ngakumbi.

3. Ubushushu bokucubungula

Zombini iiqondo lobushushu eliphezulu kakhulu nezinganeleyo zokucubungula zinokubangela ukwakheka kwe-die-building.

Amaqondo obushushu aphezulu anokukhawulezisa ukubola kwepolymer okanye ukuguquguquka kwezinto ezongezelelekileyo, ngelixa amaqondo obushushu aphantsi anokunciphisa ukunyibilika kwamanzi aze anyuse uxinzelelo lokucheba.

Ukugcina isithuba esifanelekileyo sokucubungula kubalulekile ukuze i-extrusion ihlale izinzile.

4. Uxinzelelo olugqithisileyo lokucheba

Ukukhupha okuphezulu kwe-extrusion kudla ngokunxulunyaniswa nesantya esiphezulu se-screw kunye noxinzelelo olukhulu lwe-shear.

Xa uxinzelelo kwindawo yokuphuma kwedayi ludlula amandla okunyibilika kwepolymer ukuhamba kakuhle, ukungazinzi komphezulu kunokwenzeka, okwandisa amathuba okuqokelelwa kwezinto ezijikeleze idayisi.

Zeziphi iinkqubo zePolymer ezichaphazeleka lula?

Nangona ukwakheka kwe-die kungenzeka kwizinto ezininzi ze-thermoplastic, kubonakala rhoqo kwizicelo ezifana nezi:

• Ukukhutshwa kwefilimu yePolyethylene (PE)
• Iikhompawundi zePolypropylene (PP)
• Iintambo kunye neentambo ezidityaniswe nomthwalo ophezulu we-ATH okanye we-MDH
• Iiplastiki zobunjineli ezizaliswe kakhulu
• Ukukhupha imibhobho
• Ukukhupha iprofayili

Inkqubo nganye yezinto ezibonakalayo ineempawu ezahlukeneyo zokucubungula, ngoko ke ukhetho lokongeza kufuneka lusekelwe kwifomyula ethile kunye neemfuno zokusetyenziswa.

Unga kanjaniIzongezo ezisekelwe kwiSiliconeNceda?

Enye indlela esebenzayo yokunciphisa ukwakheka kwe-die kukuphucula ukuthambisa okunyibilikayo kunye nokutshintsha intsebenziswano phakathi kwe-polymer melt kunye neendawo zokucubungula isinyithi.

I-masterbatch ye-silicone enobunzima obuphezulu be-molecular idla ngokuvavanywa ngenxa yesi sizathu kuba inokuchaphazela indlela esebenza ngayo i-melt flow ngaphandle kokutshintsha ngokupheleleyo i-polymer matrix.

Iingenelo ezinokubakho zingabandakanya:

• Ukungqubana kwe-polymer-metal okunciphileyo
• Uzinzo oluphuculweyo lokunyibilika kwamanzi
• I-torque ephantsi yokukhupha
• Iindawo zokucoca ezicocayo ngexesha lokwenziwa okuqhubekayo
• Ukuncipha kobuninzi bokucoca idayisi

Ukusebenza kokwenyani kuxhomekeke kuhlobo lwepolymer, ukwakheka kokongeza, iimeko zokucubungula, kunye nenqanaba lomthamo.

Kutheni iSilicone Masterbatch Endaweni yeZithambisi zesiqhelo?

Ii-lubricants zemveli zinokuphucula ukucubungula phantsi kweemeko ezithile, kodwa azinakubonelela rhoqo ngokulinganisela phakathi kokusebenza kakuhle kokucubungula kunye nokusebenza komphezulu ixesha elide.

I-silicone masterbatch njengesongezelelo seplastiki kunye ne-polymer modifier idibanisa ukuguqulwa kokucubungula kunye nokuphuculwa komphezulu, okwenza ukuba ifaneleke kwizicelo ezifuna zombini i-extrusion ezinzileyo kunye nomgangatho ophuculweyo wemveliso egqityiweyo.

Ngokuxhomekeke kwifomyula, i-silicone masterbatch inokuba negalelo koku:

• Ukuphuculwa kokugudiswa komphezulu
• I-coefficient ephantsi yokungqubana
• Ukumelana ngcono nokukrweleka nokurhawuzelelwa
