SILIKE Si-TPV 2150 Series ndi vulcanizate silicone-based elastomer, yopangidwa pogwiritsa ntchito ukadaulo wapamwamba wolumikizana. Izi zimabalalitsa mphira wa silicone mu SEBS ngati tinthu tating'onoting'ono, kuyambira 1 mpaka 3 ma microns pansi pa maikulosikopu. Zida zapaderazi zimaphatikiza mphamvu, kulimba, komanso kukana kwa ma abrasion a thermoplastic elastomers ndi zinthu zofunika za silikoni, monga kufewa, kumva kosalala, komanso kukana kuwala kwa UV ndi mankhwala. Kuphatikiza apo, zida za Si-TPV zimatha kubwezeretsedwanso ndipo zitha kugwiritsidwanso ntchito popanga zachikhalidwe.
Si-TPV itha kugwiritsidwa ntchito mwachindunji ngati zida zopangira, zopangidwira zofewa zomangirira pamagetsi ovala, milandu yoteteza zida zamagetsi, zida zamagalimoto, ma TPE apamwamba, ndi mafakitale a waya a TPE.
Kupitilira kugwiritsa ntchito kwake mwachindunji, Si-TPV imathanso kukhala ngati chosinthira polima komanso chowonjezera chowonjezera cha ma thermoplastic elastomers kapena ma polima ena. Imawonjezera elasticity, imathandizira kukonza, komanso imawonjezera zinthu zapamtunda. Ikaphatikizidwa ndi TPE kapena TPU, Si-TPV imapereka kusalala kwanthawi yayitali komanso kumva kosangalatsa, komanso kumathandizira kukana komanso kukwapula. Amachepetsa kuuma popanda kusokoneza zinthu zamakina ndipo amapereka ukalamba wabwino, chikasu, ndi kukana madontho. Ikhozanso kupanga mapeto ofunikira a matte pamwamba.
Mosiyana ndi zowonjezera za silicone, Si-TPV imaperekedwa mu mawonekedwe a pellet ndipo imakonzedwa ngati thermoplastic. Imabalalika bwino komanso mosiyanasiyana pamatrix onse a polima, pomwe copolymer imamangirizidwa ku matrix. Izi zimathetsa nkhawa za kusamuka kapena "kufalikira", kupangitsa Si-TPV kukhala yankho lothandiza komanso laukadaulo lokwaniritsa malo ofewa a silky mu thermoplastic elastomers kapena ma polima ena. ndipo sichifuna njira zowonjezera zowonjezera kapena zokutira.
Mndandanda wa Si-TPV 2150 uli ndi mawonekedwe a kukhudza kofewa kwapakhungu kwanthawi yayitali, kukana madontho abwino, osawonjezera pulasitiki ndi zofewetsa, ndipo palibe mvula ikagwiritsidwa ntchito kwanthawi yayitali, yomwe imakhala ngati chowonjezera cha pulasitiki ndi polima polima, makamaka moyenera. ntchito silky zosangalatsa kumva thermoplastic elastomers kukonzekera.
Kuyerekeza Zotsatira za Si-TPV Plastic Additive ndi Polymer Modifier pa TPE Performance
Si-TPV imagwira ntchito ngati njira yosinthira kumverera komanso kukonza zowonjezera za thermoplastic elastomers ndi ma polima ena. Zitha kuphatikizidwa ndi ma elastomer osiyanasiyana ndi uinjiniya kapena mapulasitiki ambiri, monga TPE, TPU, SEBS, PP, Pe, COPE, EVA, ABS, ndi PVC. Mayankho awa amathandizira kukonza magwiridwe antchito ndikuwongolera magwiridwe antchito amtundu wa abrasion wa zida zomalizidwa.
Ubwino waukulu wazogulitsa zopangidwa ndi TPE ndi Si-TPV zosakanikirana ndikupanga mawonekedwe ofewa a silky-soft-tack - ndendende zomwe ogwiritsa ntchito amayembekezera kuchokera kuzinthu zomwe amakonda kugwira kapena kuvala. Chapaderachi chimakulitsa kuchuluka kwa ntchito zomwe zingagwiritsidwe ntchito pazinthu za TPE elastomer m'mafakitale angapo. Kuphatikiza apo, kuphatikiza Si-TPV monga chosinthira kumawonjezera kusinthasintha, kukhazikika, komanso kulimba kwa zida za elastomer, ndikupangitsa kuti ntchito yopangira ikhale yotsika mtengo.
Mukuvutika Kukulitsa Kuchita kwa TPE? Si-TPV Plastic Additives ndi polima modifiersPerekani Yankho
Chiyambi cha ma TPE
Thermoplastic elastomers (TPEs) amagawidwa ndi mankhwala, kuphatikizapo Thermoplastic Olefins (TPE-O), Styrenic Compounds (TPE-S), Thermoplastic Vulcanizates (TPE-V), Polyurethanes (TPE-U), Copolyesters (COPE), ndi Copolyamides. (COPA). Ngakhale ma polyurethanes ndi ma copolyester atha kukhala opangidwa mopitilira muyeso kuti agwiritse ntchito zina, zosankha zotsika mtengo monga TPE-S ndi TPE-V nthawi zambiri zimapereka zoyenera kugwiritsa ntchito.
Ma TPE ochiritsira amaphatikiza mphira ndi thermoplastics, koma ma TPE-V amasiyana pokhala ndi tinthu tating'ono ta mphira tolumikizana pang'ono kapena kwathunthu, ndikuwongolera magwiridwe antchito awo. TPE-Vs imakhala ndi ma seti otsika oponderezedwa, kukana bwino kwa mankhwala ndi abrasion, komanso kukhazikika kwa kutentha, kuwapangitsa kukhala abwino m'malo mwa mphira mu zidindo. Mosiyana ndi izi, ma TPE ochiritsira amapereka kusinthasintha kwakukulu, kulimba kwamphamvu, kukhazikika, komanso kusinthasintha, kuwapanga kukhala oyenera pazinthu zogulira, zamagetsi, ndi zida zamankhwala. Amagwirizananso bwino ndi magawo olimba monga PC, ABS, HIPS, ndi Nylon, zomwe zimakhala zopindulitsa pakugwiritsa ntchito mofewa.
Zovuta ndi ma TPE
Ma TPE amaphatikiza elasticity ndi mphamvu zamakina komanso kusinthika, kuwapangitsa kukhala osunthika kwambiri. Makhalidwe awo otanuka, monga compression set ndi elongation, amachokera ku elastomer gawo, pamene mphamvu yokhazikika ndi yong'ambika imadalira chigawo cha pulasitiki.
Ma TPE amatha kusinthidwa ngati ma thermoplastics wamba pamatenthedwe okwera, pomwe amalowa mugawo losungunuka, kulola kupanga bwino pogwiritsa ntchito zida zopangira pulasitiki. Kutentha kwawo kogwira ntchito kumawonekeranso, kuyambira kutentha kotsika kwambiri - pafupi ndi malo osinthira magalasi a gawo la elastomer - mpaka kutentha kwambiri pafupi ndi malo osungunuka a gawo la thermoplastic - kumawonjezera kusinthasintha kwawo.
Komabe, ngakhale zabwino izi, zovuta zingapo zikupitilira kukhathamiritsa magwiridwe antchito a TPE. Chinthu chimodzi chachikulu ndizovuta kugwirizanitsa elasticity ndi mphamvu zamakina. Kukweza chinthu chimodzi nthawi zambiri kumabwera pamtengo wa chinzake, zomwe zimapangitsa kuti zikhale zovuta kwa opanga kupanga mapangidwe a TPE omwe amasunga mawonekedwe omwe amafunikira. Kuphatikiza apo, ma TPE amatha kuwonongeka pamtunda monga kukwapula ndi kuwononga, zomwe zingasokoneze mawonekedwe ndi magwiridwe antchito azinthu zopangidwa kuchokera kuzinthuzi.
