Si-TPV vulcanizate thermoplastic silicone-based elastomer ipititsa patsogolo ukadaulo wa thovu wa EVA

fotokozani:

Ethylene vinyl acetate (EVA) ndi copolymer yosunthika yomwe imapangidwa pophatikiza ethylene ndi vinyl acetate monomers. Gawo la vinyl acetate (VA) zomwe zili mu EVA zimatha kusiyana kuchokera pa 2% mpaka 60%, kulola kuti musinthe mawonekedwe ake. EVA yokhala ndi VA yotsika, pafupifupi 3 wt%, imagwiritsidwa ntchito kwambiri kusinthira polyethylene, pomwe nyimbo zokhala ndi VA zapamwamba, kuyambira 5 mpaka 50 wt%, zimapeza ntchito popanga mafilimu ocheperako, kuyika chakudya, ndi nsapato, pakati pa ena.

Si-TPV vulcanizate thermoplastic silicone-based elastomer ndi luso losintha thovu la Easy clean EVA. itha kugwiritsidwa ntchito ngati chithovu cha Modifier EVA chokhalamo, Modifier Itha kugwiritsidwa ntchito ngati chithovu cha Modifier EVA chokhalamo, chithovu cha Modifier EVA pazida zodzitetezera, thovu la Modifier EVA lazoseweretsa zomangira, chithovu cha Modifier EVA cha alonda a shin, komanso imathandizira Kukweza kwa Evaming running shoes technology kukweza. Ili ndi zabwino zochepetsera kutsika kwamafuta a thovu la EVA, kuwongolera kulimba komanso kukana abrasion, kuwongolera kupindika kwa zinthuzo, komanso kulimbikitsa mabowo kuti akhale ofananirako komanso wandiweyani.

Mosiyana ndi mnzake wa semi-crystalline, polyethylene, kuyambitsidwa kwa VA monomers kumasokoneza mapangidwe a makhiristo mu unyolo wa polima, zomwe zimapangitsa kuchepa kwa crystallinity. Pamene zomwe zili mu VA zikuchulukirachulukira, EVA imasanduka amorphous pang'onopang'ono, zomwe zimapangitsa kusintha kwa thupi ndi makina ake. Ngakhale magawo ngati elongation panthawi yopuma, kutentha kwa magalasi, ndi kachulukidwe kumawonjezeka ndi zinthu zambiri za VA, zina monga kulimba kwamphamvu, modulus, kuuma, ndi kuchepa kwa kutentha. Komabe, ngakhale kukhathamiritsa kwake kumakulitsidwa, EVA imatha kuwonetsa zofooka pakung'ambika, kukana kuvala, komanso kupsinjika, makamaka pamapulogalamu omwe amafunikira kulimba.

Kuti athane ndi zofooka izi, EVA nthawi zambiri imasakanizidwa ndi ma rubber kapena thermoplastic elastomers (TPEs), kukulitsa mphamvu zolimba, kukana misozi, kukana abrasion, komanso kulimba kwa mankhwala poyerekeza ndi EVA yoyera. Kuphatikiza EVA ndi ma TPEs monga thermoplastic polyurethane (TPU) kapena polyolefin elastomers (POE) kumawonjezera ma viscoelastic komanso kumathandizira kukonza ndi kukonzanso. Kuphatikiza apo, kutuluka kwa olefin block copolymers (OBC) kumapereka mawonekedwe a elastomeric komanso kukana kutentha kwambiri. Mapangidwe apadera a OBC, okhala ndi magawo olimba owoneka bwino komanso magawo ofewa amorphous, amathandizira magwiridwe antchito apamwamba pamapulogalamu osiyanasiyana, okhala ndi mawonekedwe ophatikizika ofanana ndi TPU ndi TPV.
Komabe, SILIKE Si-TPV vulcanizate thermoplastic silicone-based elastomer kutsogola ndi njira yochititsa chidwi kwambiri ya vulcanizate thermoplastic Silicone-based elastomer modifier. Poyerekeza ndi zosintha monga OBC ndi POE, Mfundo Zazikulu za Si-TPV ndi monga: ● Kupititsa patsogolo kukhuthala kwa zinthu zopangidwa ndi thovu la EVA ● Kupititsa patsogolo kachulukidwe ka mtundu wa zinthu zopangidwa ndi thovu la EVA ● Kuchepetsa kutentha kwa zinthu za thovu la EVA ● Konzani kuti musamavalidwe ndi thovu la EVA. Zida za thovu la EVA ● Si-TPV imatha kusintha nthawi imodzi kupindika kwapamwamba komanso kotsika kutentha kwa zinthu za thovu za EVA zolimba kwambiri.

Kugwiritsa ntchito

Mwa kuphatikiza zosintha za Si-TPV m'njira zanu zopangira, mabizinesi amatha kupanga thovu la EVA lopangidwa ndi kulimba, kulimba, ndi chitonthozo, zoperekera zinthu zosiyanasiyana, kuphatikiza nsapato, zinthu zaukhondo, zosangalatsa zamasewera, mphasa zapansi/yoga, ndi zina zambiri. .

EVA thovu Guide

Mndandanda wa Si-TPV 2250 uli ndi mawonekedwe a kukhudza kofewa kwanthawi yayitali, kukana madontho abwino, palibe plasticizer ndi zofewetsa zomwe zimawonjezeredwa, ndipo palibe mvula ikagwiritsidwa ntchito kwanthawi yayitali, makamaka yogwiritsidwa ntchito moyenera pa Super light high eco-friendly EVA. kupanga thovu kukonzekera zinthu.

Kupanga zatsopano mu EVA Foam materials (4)

Mukawonjezera Si-TPV 2250-75A, kachulukidwe ka cell ya thovu la EVA amachepa pang'ono, khoma la thovu likukulirakulira, ndipo Si-TPV imamwazikana pakhoma la thovu, khoma la thovu limakhala lolimba.

Kufananiza kwa Si-TPV2250-75A ndi polyolefin elastomer zowonjezera zowonjezera mu thovu la EVA

Ubwino waukulu

01

Sinthani kukhuthala kwa zida za thovu la EVA

Poyerekeza ndi ufa wa talcum kapena anti-abrasion agent, Si-TPV ili ndi elasticity yabwino.
02

Sinthani machulukitsidwe amtundu wa zida za thovu la EVA

Magulu ena pa Si-TPV atha kuyanjana ndi ma chromophores a utoto, kukulitsa kuchulukitsitsa kwamitundu.
03

Chepetsani kutentha kwazinthu za thovu la EVA

Kukhazikika kwa Si-TPV kumathandizira kumasula kupsinjika kwamkati kwa zinthu za thovu la EVA.
04

Sinthani kukana kwa anti-abrasion kwa zida za thovu za EVA

Si-TPV imatha kutenga nawo gawo pamachitidwe olumikizirana, omwe amawonjezera kachulukidwe wolumikizana.
05

Heterogeneous nucleation

Si-TPV imamwazikana mofanana muzinthu za thovu za EVA, zomwe zingathandize cell nucleation.
06

Chepetsani kupindika kwa zinthu za thovu za EVA

Si-TPV ili ndi magwiridwe antchito abwino kwambiri komanso otsika kutentha, ndipo nthawi imodzi imatha kusintha mawonekedwe apamwamba komanso otsika kutentha kwazinthu zolimba kwambiri za EVA thovu.

Kukhalitsa Kukhazikika

Ukadaulo wapamwamba kwambiri wopanda zosungunulira, wopanda plasticizer, wopanda mafuta ofewetsa, komanso wopanda fungo.
Kuteteza chilengedwe ndi kubwezeretsedwanso.
Amapezeka m'mapangidwe ogwirizana ndi malamulo.
