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 nthawi zambiri 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.

Tsatanetsatane

Si-TPV vulcanizate thermoplastic silicone-based elastomer ndi luso losintha thovu la Easy clean EVA. itha kugwiritsidwa ntchito ngati chithovu cha Modifier EVA chokhalira, chosinthira Itha kugwiritsidwa ntchito ngati chithovu cha EVA chokhalamo, chithovu cha Modifier EVA pazida zodzitetezera, thovu la Modifier EVA lazoseweretsa zomangira, thovu la Modifier EVA la alonda a shin, komanso litha kuthandizira kukweza kwaukadaulo wa Eva otulutsa thovu la nsapato zoyendetsa. 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.

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 thovu la EVA.

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.

EVA thovu Guide

Mndandanda wa Si-TPV 2250 uli ndi mawonekedwe a kukhudza kofewa kwanthawi yayitali, kukana madontho abwino, palibe pulasitiki ndi zofewa zomwe zimawonjezeredwa, ndipo palibe mvula ikagwiritsidwa ntchito kwanthawi yayitali, makamaka yogwiritsidwa ntchito pokonzekera zinthu za Super light eco-wochezeka za EVA.

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

Kugwiritsa ntchito

Mwa kuphatikiza zosintha za Si-TPV m'njira zanu zopangira, mabizinesi amatha kupanga zinthu za thovu za EVA zomwe zimakhala zolimba, kulimba, komanso kutonthozedwa, zomwe zimathandizira ntchito zosiyanasiyana, kuphatikiza nsapato, zinthu zaukhondo, zosangalatsa zamasewera, mphasa zapansi/yoga, ndi zina zambiri.

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 zikuphatikizapo: ● Kupititsa patsogolo kusungunuka kwa zipangizo za thovu la EVA ● Kupititsa patsogolo kusungunuka kwa mtundu wa zipangizo za thovu la EVA ● Kuchepetsa kutentha kwa zipangizo za thovu la EVA ● Kupititsa patsogolo mavalidwe a anti-abrasion a EVA foam materials ● Si-TPVature mapangidwe apamwamba kwambiri panthawi imodzi. EVA thovu zipangizo
