Si-TPV dynamic vulcanizate thermoplastic silicone-based elastomer imapititsa patsogolo ukadaulo wa thovu la EVA

fotokozani:

Ethylene vinyl acetate (EVA) ndi copolymer yogwiritsidwa ntchito mosiyanasiyana yomwe imapangidwa ndi kuphatikiza ethylene ndi vinyl acetate monomers. Chiŵerengero cha kuchuluka kwa vinyl acetate (VA) mu EVA chingasiyane kuyambira 2% mpaka 60%, zomwe zimapangitsa kuti zinthu zake zisinthe. EVA yokhala ndi kuchuluka kwa VA kochepa, pafupifupi 3% wt, imagwiritsidwa ntchito kwambiri kusintha polyethylene, pomwe zinthu zokhala ndi kuchuluka kwa VA, kuyambira 5 mpaka 50% wt, zimagwiritsidwa ntchito popanga mafilimu ofupika, ma CD, ndi nsapato, pakati pa zina.

Tsatanetsatane

Si-TPV dynamic vulcanizate thermoplastic silicone-based elastomer ndi njira yatsopano yosinthira thovu la EVA. Ingagwiritsidwe ntchito ngati thovu la Modifier EVA lopangira mipando, Modifier Ingagwiritsidwe ntchito ngati thovu la Modifier EVA lopangira mipando, thovu la Modifier EVA lopangira zida zodzitetezera, thovu la Modifier EVA lopangira zoseweretsa, thovu la Modifier EVA lopangira zoteteza ku shin guards, ndipo ingathandizenso kukweza ukadaulo wa Eva foaming running shoes. Ili ndi ubwino wochepetsa kutentha kwa thovu la EVA, kukonza kulimba mtima ndi kukana kupsinjika, kukonza kupsinjika kwa zinthuzo, ndikulimbikitsa mabowo a thovu kukhala ofanana komanso okhuthala.

Ubwino Waukulu

01

Kuonjezera kusinthasintha kwa zinthu zopangira thovu la EVA

Poyerekeza ndi ufa wa talcum kapena mankhwala oletsa kupsa, Si-TPV imakhala ndi kusinthasintha kwabwino.
02

Sinthani mtundu wa thovu la EVA

Magulu ena pa Si-TPV amatha kuyanjana ndi ma chromophores a utoto, zomwe zimapangitsa kuti mitundu ikhale yochuluka.
03

Chepetsani kuchepa kwa kutentha kwa zinthu zopangira thovu la EVA

Kutanuka kwa Si-TPV kumathandiza kumasula kupsinjika kwa mkati mwa thovu la EVA.
04

Kuonjezera kukana kwa thovu la EVA kuti lisawonongeke ndi kuuma kwa zinthu zofewa

Si-TPV imatha kutenga nawo mbali pakuchitapo kanthu kwa wothandizira wolumikizirana, zomwe zimawonjezera kuchuluka kwa kulumikizana.
05

Mitundu yosiyanasiyana ya nucleation

Si-TPV imafalikira mofanana mu thovu la EVA, lomwe lingathandize kupanga maselo.
06

Chepetsani kupsinjika kwa zinthu zopangira thovu la EVA

Si-TPV ili ndi mphamvu yabwino yolimbana ndi kutentha kwambiri komanso kotsika, ndipo nthawi yomweyo imatha kusintha kupsinjika kwa kutentha kwambiri komanso kotsika kwa zinthu za thovu la EVA.

Kukhalitsa Kukhazikika

Ukadaulo wapamwamba wopanda zosungunulira, wopanda pulasitiki, wopanda mafuta ofewetsa, komanso wopanda fungo.
Kuteteza chilengedwe ndi kubwezeretsanso zinthu.
Ikupezeka m'njira zotsatizana ndi malamulo.

Buku Lotsogolera la thovu la EVA

Si-TPV 2250 series ili ndi mawonekedwe a kukhudza kofewa komwe kumagwirizana ndi khungu kwa nthawi yayitali, kukana madontho bwino, kusakhala ndi pulasitiki ndi chofewetsa, komanso kusakhala ndi mvula pambuyo pogwiritsidwa ntchito kwa nthawi yayitali, makamaka kugwiritsidwa ntchito bwino pokonzekera zinthu zopangira thovu la EVA.

Zatsopano mu zipangizo za thovu la EVA (4)

Pambuyo powonjezera Si-TPV 2250-75A, kuchuluka kwa maselo a thovu la EVA kumachepa pang'ono, khoma la thovu limakhuthala, ndipo Si-TPV imafalikira mu khoma la thovu, khoma la thovu limakhala lolimba.

Kuyerekeza kwa Si-TPV2250-75A ndi zotsatira zowonjezera za polyolefin elastomer mu thovu la EVA

Kugwiritsa ntchito

Mwa kuphatikiza ma modifier a Si-TPV mu njira zanu zopangira, mabizinesi amatha kupanga zinthu za thovu la EVA zomwe zimakhala ndi mphamvu zowonjezera, kulimba, komanso chitonthozo, zomwe zimagwira ntchito zosiyanasiyana, kuphatikizapo nsapato, zinthu zaukhondo, zinthu zosangalatsa pamasewera, mphasa zapansi/yoga, ndi zina zambiri.

Mosiyana ndi polyethylene, yomwe ndi semi-crystalline counterpart, kuyambitsidwa kwa ma monomers a VA kumasokoneza mapangidwe a makristalo mu unyolo wa polymer, zomwe zimapangitsa kuti crystallinity ichepe. Pamene kuchuluka kwa VA kukukwera, EVA imakhala yosasinthika pang'onopang'ono, zomwe zimapangitsa kuti zinthu zake zisinthe komanso zisinthe. Ngakhale magawo monga kutalika kwa VA ikasweka, kutentha kwa kusintha kwa galasi, ndi kuchuluka kwa VA kumawonjezeka, zina monga mphamvu yolimba, modulus, kuuma, ndi kutentha kosungunuka kumachepa. Komabe, ngakhale kuti imakula kwambiri, EVA ikhoza kuwonetsa zofooka mu mphamvu yong'ambika, kukana kuwonongeka, ndi kupsinjika, makamaka pakugwiritsa ntchito komwe kumafuna kulimba.

Pofuna kuthana ndi zofooka izi, EVA nthawi zambiri imasakanizidwa ndi ma rabara kapena ma elastomer a thermoplastic (TPEs), zomwe zimapangitsa kuti mphamvu ya tensile ikhale yolimba, kukana kung'ambika, kukana kukwawa, komanso kulimba kwa mankhwala poyerekeza ndi EVA yeniyeni. Kuphatikiza EVA ndi ma TPE monga thermoplastic polyurethane (TPU) kapena polyolefin elastomers (POE) kumawonjezera mphamvu za viscoelastic ndipo kumathandizira kukonza ndi kubwezeretsanso. Kuphatikiza apo, kutuluka kwa olefin block copolymers (OBC) kumapereka mawonekedwe a elastomeric komanso kukana kutentha kwambiri. Kapangidwe kapadera ka OBC, komwe kali ndi magawo olimba opangidwa ndi crystallizable ndi magawo ofewa a amorphous, kumathandiza kuti magwiridwe antchito apamwamba kwambiri pa ntchito zosiyanasiyana, ndi mphamvu zomangika zofanana ndi TPU ndi TPV.
Komabe, SILIKE Si-TPV dynamic vulcanizate thermoplastic silicone-based elastomer advanced ndi njira yatsopano yosinthira thermoplastic Silicone-based elastomer. Poyerekeza ndi zosintha monga OBC ndi POE, Mfundo Zazikulu za Si-TPV ndi izi: ● Kukweza kulimba kwa zinthu za thovu la EVA ● Kukweza mtundu wa zinthu za thovu la EVA ● Kuchepetsa kutentha kwa zinthu za thovu la EVA ● Kukweza kukana kwa abrasion kwa zinthu za thovu la EVA ● Si-TPV imatha kusintha nthawi imodzi kusintha kwa kutentha kwapamwamba komanso kotsika kwa zinthu za thovu la EVA.
