I-Snapelastomer 2802 Engatyibilikiyo kwaye Ingagugiyo ye-EVA
chaza:
I-Snapelastomer 2802 sisilungisi se-elastomer esisebenza kakuhle kwiinkqubo ze-EVA kunye ne-TPU, esenzelwe ukuphucula ukumelana nokukrweleka kunye neempawu zokubambelela.
Inika ukubambelela okuthembekileyo phantsi kweemeko ezomileyo nezimanzi ngelixa igcina ukuqina, okwenza ifaneleke kwimidlalo, izihlangu ezingaqhelekanga, zefashoni, kunye nezihlangu zesikhumba.
Le nto isasazeka kakuhle kwi-EVA kunye ne-TPU matrices, iqinisekisa ukucutshungulwa okuzinzileyo kunye neziphumo ezihambelanayo. Isebenzisa indlela ye-viscoelastic, yonyusa amanqanaba okungqubana endaweni yokuwanciphisa, iphucula ngempumelelo ukumelana nokutyibilika kwiindawo ezimanzi. Kumanqanaba okulayisha acetyiswayo, igcina ingqibelelo yoomatshini bezinto ezisisiseko. Iyahambelana neenkqubo zokubumba i-foam, i-extrusion, kunye ne-injection.
THUMELA I-IMEYILE KUTHI I-Snapelastomer 2802 Elastomer engatyibilikiyo kwaye engagugiyo
I-Snapelastomer 2802 sisiguquli se-elastomer esisebenza kakuhle esenzelwe iinkqubo ze-EVA kunye ne-TPU, esibonelela ngokumelana nokuguguleka okuphuculweyo kunye nokusebenza okuthembekileyo kokubambelela.
Ngokusebenzisa indlela ye-viscoelastic, iyakwandisa ngempumelelo ukungqubana phantsi kweemeko ezomileyo nezimanzi, inceda ekuthinteleni ukutyibilika, ingakumbi kwiindawo ezichatshazelwe kukufuma.
Le nto inika indlela ebalaseleyo yokusasazeka kunye nendlela yokucubungula ezinzileyo, okwenza kube lula ukuyidibanisa neenkqubo zokubumba ngefoam, extrusion, kunye ne-injection. Ibonelela ngophuculo lokusebenza ngelixa igcina iipropati zoomatshini zezinto ezisisiseko, iqinisekisa indibaniselwano elungeleleneyo yokuqina nokusebenza. Ilungele ukusetyenziswa kwezihlangu kuquka ezemidlalo, izihlangu ezingaqhelekanga, izihlangu zefashoni, kunye nezihlangu zesikhumba apho kufuneka ukhuseleko, ukubamba, kunye nobude bexesha.
Iingenelo eziphambili
1) Ukuphucula ukumelana nokuguguleka kunye neempawu zokungatyibiliki kwe-EVA;
2) Ubungakanani bokuguguleka kwemveliso ye-DIN bunokuncipha kakhulu, kwaye ukumelana nokuguguleka kuphuculwe kakhulu, nto leyo eyandisa ubomi benkonzo yomphezulu wezihlangu ngempumelelo;
3) Ngokungafaniyo nezongezo zemveli zokuxhathisa ukuguguleka ezinciphisa i-friction coefficient, le mveliso, ngokusebenzisa indlela ye-viscoelastic, inokunyusa i-friction coefficient eyomileyo/emanzi yezinto, isombulule ingxaki "yokutyibilika xa amanzi ekhona" kwi-EVA sole;
4) Emva konyango lokuhambelana kojongano, iSnapelastomer2802 inosasazeko oluhle kwinkqubo ye-EVA foaming;
5) Kwidosi ecetyiswayo, ayinampembelelo ingako kumandla okutsalwa, amandla okukrazula kunye nobunzima bezinto ezisisiseko, kwaye inokufezekisa utshintsho olusebenzayo ngaphandle kokulahla iipropati ezisisiseko……
