I-Si-TPV dynamic vulcanizate thermoplastic silicone-based elastomer iphucula iteknoloji ye-EVA foam

chaza:

I-Ethylene vinyl acetate (EVA) yi-copolymer eguquguqukayo eyenziwe ngokuxuba i-ethylene kunye ne-vinyl acetate monomers. Umlinganiselo womxholo we-vinyl acetate (VA) kwi-EVA unokwahluka ukusuka kwi-2% ukuya kwi-60%, okuvumela ukuba iipropati zayo zenziwe ngokwezifiso. I-EVA enomxholo we-VA ophantsi, malunga ne-3 wt%, isetyenziswa rhoqo ukuguqula i-polyethylene, ngelixa izinto ezinomxholo we-VA ophezulu, ukusuka kwi-5 ukuya kwi-50 wt%, zifumana usetyenziso ekwenzeni iifilimu ezinciphayo, ukupakisha ukutya, kunye nezihlangu, phakathi kwezinye.

Ukuqina Uzinzo

Itekhnoloji ephucukileyo engenazinyibilikisi, ayinaplastiki, ayinaoyile yokuthambisa, kwaye ayinavumba.
Ukukhuselwa kwendalo kunye nokuphindeka kwayo.
Ifumaneka kwiifomyula ezithobela imithetho.

Isikhokelo sokufutha i-EVA

Uthotho lweSi-TPV 2250 luneempawu zokuchukumisa ulusu ixesha elide, ukumelana namabala, akukho plasticizer kunye nesithambisi esongeziweyo, kwaye akukho mvula emva kokusetyenziswa ixesha elide, ngakumbi esetyenziselwa ukulungiselela izinto ze-EVA ezithambileyo ezikhazimlayo nezinobuhlobo nendalo.

Uyilo olutsha kwizixhobo ze-EVA Foam (4)

Emva kokongeza i-Si-TPV 2250-75A, uxinano lweeseli zebhamuza ze-EVA foam luyancipha kancinci, udonga lwebhamuza luba lukhuni, kwaye i-Si-TPV isasazeka eludongeni lwebhamuza, udonga lwebhamuza luba rhabaxa.

Isicelo

Ngokufaka ii-modifier ze-Si-TPV kwiinkqubo zakho zokuvelisa, amashishini anokuvelisa izixhobo ze-foam ze-EVA ezinezinto eziphucukileyo zokuqina, ukuqina, kunye nentuthuzelo, ezilungele ukusetyenziswa ngeendlela ezahlukeneyo, kubandakanya izihlangu, iimveliso zococeko, izinto zokuzonwabisa kwezemidlalo, iimathi zomgangatho/i-yoga, nokunye.

Ngokungafaniyo ne-semi-crystalline counterpart yayo, i-polyethylene, ukungeniswa kwee-VA monomers kuphazamisa ukwakheka kweekristale kwi-polymer chain, nto leyo ebangela ukuncipha kwekristale. Njengoko umxholo we-VA usanda, i-EVA iba yi-amorphous ngokuthe chu, nto leyo ekhokelela kutshintsho kwiimpawu zayo zomzimba nezoomatshini. Ngelixa iiparameter ezifana nokwandiswa ngexesha lokuqhekeka, ubushushu bokutshintsha kweglasi, kunye noxinano zinyuka ngomxholo we-VA ophezulu, ezinye ezifana namandla okuxinana, i-modulus, ubulukhuni, kunye nobushushu bokunyibilika ziyancipha. Nangona kunjalo, nangona i-elasticity yayo iphucukile, i-EVA inokubonisa ukusilela kwamandla okukrazula, ukumelana nokuguguleka, kunye neseti yokucinezelwa, ngakumbi kwizicelo ezifuna ukuqina.

Ukuze koyiswe le mida, i-EVA idla ngokuxutywa neerabha okanye ii-thermoplastic elastomers (TPEs), nto leyo ephucula amandla okutsalwa, ukumelana nokukrazuka, ukumelana nokukrweleka, kunye nokuqina kweekhemikhali xa kuthelekiswa ne-EVA ecocekileyo. Ukudibanisa i-EVA nee-TPE ezifana ne-thermoplastic polyurethane (TPU) okanye i-polyolefin elastomers (POE) kuphucula iimpawu ze-viscoelastic kwaye kwenza kube lula ukucubungula kunye nokurisayikilisha. Ukongeza, ukuvela kwee-olefin block copolymers (OBC) kunika iimpawu ze-elastomeric kunye nokumelana nobushushu obuphezulu. Ulwakhiwo olukhethekileyo lwe-OBC, oluquka iinxalenye ezinzima ezikristalekayo kunye neenxalenye ezithambileyo ezingafaniyo, luvumela ukusebenza okuphezulu kwizicelo ezahlukeneyo, kunye neempawu zeseti yokucinezelwa ezifana ne-TPU kunye ne-TPV.
Nangona kunjalo, i-SILIKE Si-TPV dynamic vulcanizate thermoplastic silicone-based elastomer advanced yi-vulcanizate thermoplastic Silicone-based elastomer modifier entsha. Xa kuthelekiswa nee-modifiers ezifana ne-OBC kunye ne-POE, iiMbaluleka eziphambili ze-Si-TPV ziquka: ● Ukuphucula ukuthamba kwezinto ze-foam ze-EVA ● Ukuphucula ukugcwala kombala wezinto ze-foam ze-EVA ● Ukunciphisa ukushwabana kobushushu bezinto ze-foam ze-EVA ● Ukuphucula ukumelana nokuguguleka kwezinto ze-foam ze-EVA ● I-Si-TPV inokuphucula ngaxeshanye ukuguquguquka koxinzelelo oluphezulu nolusezantsi lwezinto ze-foam ze-EVA ezinzima kakhulu.
