ETPU Zvishandiso Zvokupupuma Zvine Zvimwe Zvisina kukwana
chinyakare EVA furo zvinhu zvine kusimba kusimba, uye mushure mekupfeka kwenguva yakati rebei, iyo inodonha uye inodonha. Kugadzirisa zvinhu nePOE, rabha, uye zvimwe zvinhu zvinogona kugadzirisa nekuvandudza zvinhu zvemukati, asi kuvandudza kune kushoma. Panguva imwecheteyo, kune nyaya dzakadai sepamusoro shrinkage uye kuoma mukuumba. Maitiro ekugadzira anoshandisa makemikari anoita furo, ayo asingakonzere chete kusvibiswa kune zvakatipoteredza asiwo anoburitsa zvinokuvadza kumuviri wemunhu.
ETPU zvimedu zvinopupuma zvine ultra-light density, ultra-high resilience, uye shandisa supercritical carbon dioxide seanopupa mumiririri mukugadzirira. Iwo anogadzirwa neakachena muviri foaming nzira, iyo yakasvibira, ine hushamwari nharaunda, isina kusvibiswa-isina, uye isina masara emakemikari. Zvisinei, ikozvino ETPU zvinhu zvinopupa zvichine zvinotevera zvinokanganisa.
1.Parizvino, iyo foaming particle gadziriro tekinoroji haina kukura zvakakwana, uye kugadzirira kwe ETPU zvimedu zvinotsamira zvakanyanya pane ruzivo. The TPU nzira yekupupa uye maitiro ayo haanyatso kunzwisiswa, uye makambani mashoma chete anogona kuagadzira akawanda, izvo zviri kure nekuzadzisa kudiwa kwemusika. ETPU kupupa zvinhu.
2.Kana TPU tupukanana tunobuda furo hachina kuitiswa mushure mekugadzira kurapwa, twumafuro tunopera zvishoma nezvishoma kusvika hwanyatsobatana. Parizvino, nzira mbiri dzekugadzira dzakatsanangurwa: kukurumidza kutonhora kuumba nzira uye kumanikidza-kubata mhepo muripo nzira.
3.Kukurumidza midziyo inoderedza, iyo yakazara uye inopenya ETPU foamingmaterialsparticles ichave, uye iyo yakakwirira iyo rebound elasticity. Nekuda kwekusakwanisa kwemidziyo iripo yekusangana nepamusoro depressurization rate inodiwa TPU kupupa, kumwe kuvandudzwa kwemidziyo yekupupa kunodiwa.
4. Mu TPU kupisa furo maitiro, thermocouple kupisa tsvimbo dzinowanzo shandiswa kupisa, izvo zvinokonzeresa kusaenzana kupisa kwezvikamu, zvichitungamira kukusaenderana saizi ye. ETPU zvimedu. Zvimedu zvakagadzirirwa zvine furo zvine huremu hwepamusoro, hwakakasharara, hutete hwakanyanya, uye kushomeka kwekudzivirira kune yero uye hydrolysis yezvimedu.
5.Pakati pekugadzirisa kwekugadzira midsole mukati ETPU shangu, iyo yakajairwa-yepamusoro-tembiricha tembiricha welding yekuumba nzira inogona kukonzera isina kukwana welding uye nemapatani asina kujeka epamhepo, kunyanya yepolyester-yakavakirwa. TPU, iyo inogona kuita hydrolysis uye kushanduka yero pasi pehutsi hwemvura hwakanyanya kupisa.
6.Parizvino, vazhinji vakagadzirirwa ETPU furo zvinhu zvimedu zvinhu zvine ruvara rumwe. Pane nzira mbiri dzekuwana mavara ETPU: kudhaya kwakananga kwe TPU furo rine pigment kana kuunza mapolols akadhayiwa kugadzirira mavara TPU isati yapupuma furo.
Kudhaya kwakananga kwe TPU furo rine pigment rinopa nyaya hombe uye inonetsa, inova kutama kwe pigment kunotungamira mukusiyana kwemavara muchigadzirwa chekupedzisira. Izvi zvinonyanya kutaridzika mukupisa kwemvura kuumbwa kwemhepo, uko kudziya kwemaitiro kunowedzera kukurudzira kutama kwemavara madiki mamorekuru uye kunowedzera kusiyanisa kwemavara.
Kuunza ma polyols akadhayiwa kugadzirira mavara TPU isati yapupuma inobvumira madhayi kuti apararire mune microscopic fomu mukati me polymer cheni. Nerubatsiro rwekubatanidza maajenti senge silane, mamorekuru edhayi anonamirwa pamaketani epolymer, kudzivirira kufamba kwemamorekuru edhayi mukati. TPU pasi pemhepo inopisa yemvura. Nekudaro, maitiro aya anosanganisira zvinhu polymerization uye ane yepamusoro maitiro kuoma.
