Ukuqina kwefoam okusebenzayo kakhulu, induduzo elula, kanye nokusebenza kahle kwezinto ezihlanzekile.

Njengoba isidingo somhlaba wonke siqhubeka nokukhula kwezinto ze-foam ezilula, eziqinile, nezihlala isikhathi eside, izinhlelo ze-EVA ezivamile (i-ethylene-vinyl acetate) ziya ngokuya zihlolwa kabusha ngenxa yemikhawulo yazo yokusebenza yesikhathi eside. Izinselele ezivamile—njengokunciphisa i-rebound, ukuncipha kokushisa, ukuguqulwa kokucindezela, kanye nokufuduka kwezengezo—zivame ukuthinta ukuhambisana komkhiqizo, ukuqina, kanye nolwazi lomsebenzisi kuzo zonke izicathulo, ezemidlalo, kanye nezicelo zezimboni.

Ngokuphikisana nalesi simo,I-Si-TPV 2250-75A, i-elastomer ye-thermoplastic esekelwe ku-silicone eyenzelwe ukuguqulwa kwe-foam ye-EVA, iyahlolwa njengendlela ehlukile yezinto ezibonakalayo. Yakhelwe ngesigaba se-silicone esivundile esisakazwa ngaphakathi kwe-matrix ye-thermoplastic, izinto zethula indlela ehlukile yokubhekana nezithiyo zesakhiwo kanye nokucubungula ezinhlelweni ze-foam ze-EVA.

Ukucabanga Kabusha Ngezinselele Zokwenza I-EVA Foam

Ukukhiqizwa kwe-foam ye-EVA kuvame ukuhilela ukusebenzisana okuyinkimbinkimbi phakathi kwama-chemical blowing agents, ukusabela kokuxhumanisa, kanye ne-melt rheology. Ukwehluka kwamafasitela okushisa kanye nebhalansi yokwakheka kungaholela ekuguqukeni kwesimo samaseli okungaguquki, ukungazinzile kobukhulu, kanye nokushintshashintsha kokusebenza komshini. Ngaphezu kwalokho, iziguquli zendabuko—njenge-SEBS, ama-plasticizer, noma izithasiselo ezisekelwe ku-oyela—zingabangela izinkinga zesikhathi eside kufaka phakathi ukuqina kobuso, ukufuduka, kanye nokwehla kokusebenza kancane kancane.

I-Si-TPV 2250-75A ibekwe njengento esebenzisana nalesi simiso ngendlela ehlukile. Isakhiwo sayo esincane, esakhiwe yizizinda zerabha ze-silicone ezihlakazekile kahle (cishe i-1–3 μm), singasebenza njengezindawo ze-nucleation ezingafani ngesikhathi sokuqhuma kwe-foam. Lesi sici sesakhiwo sihlotshaniswa nokwakheka kokusatshalaliswa kwamaseli okufanayo kanye nokuqiniswa kwe-foam okuthuthukisiwe ngaphansi kwezimo zokucubungula ezilawulwayo.

I-Foam Morphology kanye nokuziphatha okulinganayo

Ukufana kwesakhiwo se-foam kuvame ukudlala indima ekunqumeni ukuzinza komshini kanye nekhwalithi yobuso. Ukufakwa kwe-Si-TPV 2250-75A ekwakhiweni kwe-EVA kuye kwahlotshaniswa nezakhiwo zamaseli ezincanyana kanye nezici zobuso obubushelelezi. Lezi zinguquko zingase zibe negalelo ekuthuthukisweni kokuvumelana kobuhle kanye nokwehluka okuncishisiwe phakathi kwamaqoqo okukhiqiza.

Ukuncipha kokushisa, inkinga eyaziwayo kuma-foam e-EVA, kungathonywa nokuba khona kwezizinda ze-silicone ezivuvuke ngokuguquguqukayo. Ngokufaka isandla ekuqinisweni kwesakhiwo sangaphakathi kanye nokuzinza kwenethiwekhi ye-crosslink, izinto zingasiza ekushintsheni okulinganiselwe kobukhulu ngesikhathi sokupholisa kanye nokusetshenziswa kwesikhathi eside. Lokhu kuziphatha kungaba yinto efanele kuzinhlelo zokusebenza ezidinga ukubekezelelana okuqinile kanye nokugcinwa kwesimo okuthuthukisiwe.

Isiguquli se-EVA esingenapulasitiki esihlinzeka ngobumnene besikhumba isikhathi eside, ukumelana namabala, kanye nokusebenza okuzinzile ngaphandle kwemvula.

Ukusebenza kokubuyela emuva okunamandla okuzinzile kokusika isikhathi eside.

Ukucatshangelwa Kokuqina Nokusebenza Kwesikhathi Eside

Ezinhlelweni zezicathulo kanye nezokuhlalisa, ukusebenza kwe-rebound kanye nokubuyiselwa kwamandla kuvame ukuba yizilinganiso ezibalulekile. Izinto ezivamile ze-EVA zingase zilahlekelwe kancane kancane ukuqina ngenxa yemijikelezo yokucindezela ephindaphindwayo. I-Si-TPV 2250-75A ibonwe isekela ukugcinwa kwe-rebound ngokuhamba kwesikhathi, okungenzeka ibe negalelo ekuziphatheni kwe-rebound okuqhubekayo kuyo yonke imijikelezo yokuphila komkhiqizo.

Ukungabikho kwama-plasticizer anesisindo esincane sama-molecule ngaphakathi kwesakhiwo kunganciphisa namathuba okufuduka kobuso. Lesi sici sivame ukuhlotshaniswa nobuso obuthintwayo kanye nokuthambekela okunciphile, okungaba wusizo ekugcineni ukubukeka komkhiqizo kanye nezici zokuphatha ngesikhathi sokusetshenziswa isikhathi eside.

Ibhalansi Yesakhiwo Esilula Nokuqina

Ukukhethwa kwezinto zokusetshenziswa kwe-foam yesimanje kuvame ukudinga ukulinganisela ukunciphisa isisindo nokuqina kwemishini. I-Si-TPV 2250-75A isetshenziswe ekwakhiweni okuqondiswe ezakhiweni ze-foam eziphansi ngenkathi kugcinwa ukumelana nokuguguleka kanye nokuguquguquka kokucindezelwa. Lezi zimfanelo zingase zisekele isikhathi eside somkhiqizo ezisetshenziswayo ezicindezelwe ngokuphindaphindiwe kwemishini.

Ngaphezu kwalokho, ukuthuthukiswa kokumelana nokuguguleka kanye nokuqina kwesakhiwo kunganciphisa izinga lokuwohloka kokusebenza, okungaba yinto efanele ezindaweni ezisetshenziswa kakhulu njengezicathulo zemidlalo noma izinhlelo zokuvikela izicathulo.

Ukuhambisana Kokucubungula kanye Nemiphumela Yokukhiqiza

Ngokombono wokukhiqiza, ukuhambisana kwezinto ezibonakalayo nengqalasizinda yokucubungula ekhona kuvame ukuba yinto ebalulekile okufanele icatshangelwe. I-Si-TPV 2250-75A ibikwe ukuthi iyahambisana namasu okucubungula i-thermoplastic ajwayelekile, okuhlanganisa i-extrusion, i-injection molding, kanye nezinqubo zokuhlanganisa i-foam.

Ukuziphatha kwayo kwe-rheological kungabangela izici zokugeleza ezizinzile ngesikhathi sokucubungula, okungenzeka kusekele ukuhambisana okuthuthukisiwe kuyo yonke imijikelezo yokukhiqiza. Lokhu kuzinza kungahlotshaniswa nokwehluka kokucubungula okuncishisiwe, ukusetshenziswa kwamandla okuphansi, kanye nezingxenye ezimbalwa ezilahliwe, kuye ngokuthi kuklanywe kanjani kanye nezimo zokusebenza.

Ububanzi Besicelo Kuzo Zonke Izimboni

Ukusetshenziswa okungenzeka kwe-Si-TPV 2250-75A kuhilela imikhakha eminingi lapho ukusebenza kwe-foam kudlala indima ebalulekile. Lokhu kufaka phakathi:

Izicathulo eziphakathi kanye nezingaphakathi ezidinga ukuqina okuqinile kanye nokuqina kobukhulu

Imikhiqizo yezemidlalo kanye neyokuzilibazisa efana nama-yoga mat kanye ne-protective padding

Izingxenye zokusika zezimboni kanye nezakhiwo ezimunca ukushaqeka

Izinto zokupakisha ezilula ezenzelwe ukumelana nokushayisana

Kuzo zonke lezi zindawo zokusetshenziswa, izinto ezisetshenziswayo ziyacatshangelwa ngenxa yekhono lazo lokuthonya isakhiwo se-foam, ukusebenza kahle kwemishini, kanye nokuziphatha kokucubungula ngaphakathi kwezinhlelo ezisekelwe ku-EVA.

Imibono Yokuphepha Kwezemvelo Nezinto Ezibonakalayo

Ukwanda kokunaka umthelela wemvelo kanye nokuphepha kwezinto kuye kwathonya ukuthuthukiswa kwezinhlelo ze-foam ezihlukile. Izinhlobo ze-EVA zendabuko zingafaka izithasiselo ezikhipha ama-molecule amancane ngokuhamba kwesikhathi, okungaphakamisa ukukhathazeka okuhlobene nephunga, ukukhishwa kwegesi, kanye nokuvezwa isikhathi eside.

I-Si-TPV 2250-75A ichazwe njengohlobo olungathembeli kuma-plasticizer noma kuma-ejenti okuthambisa asekelwe ku-oyela. Lo mehluko wokwakheka ungaba nomthelela ekunciphiseni ukuziphatha kokufuduka kanye nokuthuthukiswa kokuqina kwezinto, okuhambisana nemizamo ebanzi yemboni yokuxazulula izixazululo zezinto ezihlanzekile nezisimeme.

Ukwakheka okubonakalayo kobuchwepheshe obuphezulu okubonisa izixazululo ze-foam eziguquguqukayo kuzo zonke izicathulo, ukufaneleka, izimboni, kanye nezinhlelo zokusebenza zokupakisha.

Ukuqhathaniswa okuseceleni okubonisa ukuzinza okuthuthukisiwe kobukhulu, ukuhlanzeka, kanye nokusebenza okungenapulasitiki.

Indlela Ebonakalayo Yokuthuthukisa Uhlelo Lwe-Foam

Esikhundleni sokuthembela kuphela ekulungisweni kokwakheka okuqhubekayo, i-Si-TPV 2250-75A ibonisa ushintsho olubanzi ekuthuthukisweni okuqhutshwa yizinto ezibonakalayo kwezinhlelo ze-foam ze-EVA. Ngokusebenzisana nezinqubo ze-foam kanye ne-crosslinking, yethula uhlaka oluhlukile lokubhekana nezinselele zesikhathi eside ezihlobene nokungaguquguquki, ukuqina, kanye nokulawulwa kwenqubo.

Njengoba abakhiqizi beqhubeka nokuhlola izindlela ezintsha zokuthuthukisa ukusebenza kwe-foam ye-EVA, izinto ezifana ne-Si-TPV 2250-75A zingadlala indima ekwenzeni kube lula ukuklama i-foam elawulwa kakhulu, eguquguqukayo, futhi eqondene nohlelo lokusebenza.
