Si-TPV 3400-55A Elastomer Yofewa, Yolimba ya Silicone Yopangira Zigawo Zopangira Injection
fotokozani:
SILIKE Si-TPV 3400-55A thermoplastic elastomer ndi dynamic vulcanized thermoplastic silicone based elastomer yomwe imapangidwa ndi ukadaulo wapadera wogwirizana kuti ithandize rabara ya silicone kufalikira mu TPU mofanana ngati tinthu ta 2 ~ 3 micron pansi pa maikulosikopu. Zipangizo zapaderazi zimaphatikiza mphamvu, kulimba ndi kukana kukwawa kwa elastomer iliyonse ya thermoplastic ndi zinthu zabwino za silicone: kufewa, kumva ngati silika, kuwala kwa UV ndi kukana mankhwala komwe kumatha kubwezeretsedwanso ndikugwiritsidwanso ntchito popanga zinthu zachikhalidwe.
TUMIZANI Imelo Kwa Ife Mapulogalamu
Si-TPV 3400-55A Silicone thermoplastic elastomer imatha kugwirizana bwino ndi TPE ndi zinthu zina za polar, monga polypropylene (PP), nayiloni (PA), polyethylene (PE), ndi polystyrene (PS). Elastomer iyi yochezeka ndi zachilengedwe imapereka mphamvu zofewa zogwira, kulimba, komanso kukana kukwawa, zomwe zimapangitsa kuti ikhale yoyenera kugwiritsa ntchito zinthu zogwiritsidwa ntchito pafoni, ma key caps, ma rollers, ndi zida zina zamagetsi. Kugwira ntchito kwake kwa nthawi yayitali kumatsimikizira kuti imamveka bwino ngakhale ikagwiritsidwa ntchito pafupipafupi, pomwe kulimba kwake kumapangitsa kuti ikhale yoyenera kugwiritsidwa ntchito kwambiri. Kaya ndi jekeseni kapena overmolding yofewa, Si-TPV 3400 Series Dynamic vulcanized thermoplastic silicone elastomer imapereka chitonthozo chokwanira, magwiridwe antchito, komanso moyo wautali.

● Kukonza Kwachiwiri
Monga zinthu zogwiritsidwa ntchito mu thermoplastic, zinthu za Si-TPV zitha kukonzedwanso kuti zigwiritsidwe ntchito pazinthu wamba.
● Kupanikizika kwa Kupaka Jekeseni
Kupanikizika kwa chogwirira kumadalira kwambiri mawonekedwe, makulidwe ndi malo a chipata cha chinthucho. Kupanikizika kwa chogwirira kuyenera kuyikidwa pamtengo wotsika poyamba, kenako pang'onopang'ono kukwera mpaka palibe zolakwika zina zomwe zimawoneka mu chinthu chopangidwa ndi jakisoni. Chifukwa cha mphamvu zotanuka za chinthucho, kupanikizika kwambiri kwa chogwirira kungayambitse kusintha kwakukulu kwa gawo la chipata cha chinthucho.
● Kupanikizika kwa msana
Ndikofunikira kuti mphamvu yakumbuyo ikabwerera m'mbuyo ikhale 0.7-1.4Mpa, zomwe sizingotsimikizira kuti kusungunuka kwa kusungunuka kumagwirizana, komanso zimatsimikizira kuti zinthuzo sizikuwonongeka kwambiri ndi kudulidwa. Liwiro la screw lomwe limalimbikitsidwa la Si-TPV ndi 100-150rpm kuti zitsimikizire kusungunuka kwathunthu ndi pulasitiki ya zinthuzo popanda kuwonongeka kwa zinthu chifukwa cha kutentha kwa shear.
Ndemanga:
1. Zinthu zopangidwa ndi elastomer za Si-TPV zitha kupangidwa pogwiritsa ntchito njira zodziwika bwino zopangira thermoplastic, kuphatikizapo overmolding kapena co-molding ndi ma substrates apulasitiki monga PP,PA.
2. Kumveka kosalala kwambiri kwa Si-TPV elastomer sikufuna njira zina zowonjezera zokonzera kapena zokutira.
3. Mikhalidwe ya ndondomekoyi ingasiyane malinga ndi zida ndi njira zake.
4. Kuwumitsa kochotsa chinyezi m'malo ouma kumalimbikitsidwa nthawi zonse.
Phukusi:
25KG / thumba, thumba la pepala lopangidwa ndi manja lokhala ndi thumba lamkati la PE.
Nthawi yosungira ndi kusunga zinthu:
Sungani pamalo ozizira komanso opumira bwino.
Makhalidwe oyambirira amakhalabe osasintha kwa miyezi 12 kuyambira tsiku lopanga ngati asungidwa m'malo osungira omwe amalangizidwa.
