TPE raw material ndeye zvakatipoteredza, isiri-chepfu uye yakachengeteka chigadzirwa, ine huwandu hwakasiyana hwekuoma (0-95A), yakanakisa colorability, kunyorova kubata, kuramba mamiriro ekunze, kuneta kuramba uye kupisa kupisa, kuita kwakanakisa kugadzirisa, hapana chikonzero Vulcanized, uye inogona kudzokororwa kuti ideredze mutengo, saka, TPE mbishi zviwanikwa zvinoshandiswa zvakanyanya mukuumba jekiseni, extrusion, blow molding, kuumba uye kumwe kugadzirisa. Saka iwe unoziva izvo zvinodiwa kune iyojekiseni kuumbamaitiro eTPE mbishi zvinhu? Ngationei zvinotevera.
TPE mbishi zvinhu jekiseni kuumba maitiro zvinodiwa:
1. Pukuta TPE mbishi zvinhu.
Kazhinji, kana paine zvakaomesesa zvinodiwa pamusoro pezvigadzirwa zveTPE, iyo TPE mbishi zvinhu zvinofanirwa kuomeswa isati yaumbwa jekiseni. Nekuti mukugadzira jekiseni rekugadzira, TPE mbishi zvinhu zvinowanzo kuve neakasiyana madhigirii ehunyoro uye mamwe akawanda akadzikama-mamorekuru-huremu mapolymer. Naizvozvo, mvura yemukati yeTPE mbishi zvinhu inofanira kuyerwa kutanga, uye iyo ine yakawandisa mvura yemukati inofanira kuomeswa. Iyo yakawanda yekuomesa nzira ndeye kushandisa dhishi yekuomesa kuti iome pa60 ℃ ~ 80 ℃ kwemaawa maviri. Imwe nzira ndeyekushandisa yekuomesa kamuri hopper, iyo inogona kuramba ichipa yakaoma inopisa zvinhu kumushini wekuumba jekiseni, iyo inobatsira kurerutsa mashandiro, kuchengetedza hutsanana, kuvandudza mhando, uye kuwedzera jekiseni.
2. Edza kudzivisa kuumbwa kwejekiseni rekushisa kwepamusoro.
Pasi pechimiro chekuona kunaka kweplasticization, tembiricha yeextrusion inofanira kudzikiswa zvakanyanya sezvinobvira, uye iyo jekiseni yekumanikidza uye screw speed inofanira kuwedzerwa kuderedza viscosity yekunyunguduka uye kugadzirisa fluidity.
3. Isa yakakodzera TPE jekiseni tembiricha.
Mukuita majekiseni ekuumba TPE mbishi zvinhu, iyo yakajairika tembiricha yekumisikidza nzvimbo yega yega ndeye: dhiramu 160 ℃ kusvika 210 ℃, nozzle 180 ℃ kusvika 230 ℃. Tembiricha ye mold inofanirwa kunge yakakwira kupfuura tembiricha yekumisikidza yenzvimbo yekuumba jekiseni, kuitira kudzivirira mitsetse iri pamusoro pechigadzirwa uye hurema hwejekiseni inoumba inotonhora glue, saka tembiricha yekuumbwa inofanira kugadzirwa kuti ive pakati. 30 ℃ uye 40 ℃.
4. Kumhanya kwejekiseni kunofanira kubva kunononoka kusvika kutsanya.
Kana iri mazinga akati wandei ejekiseni, kumhanya kunobva kunonoke kusvika pakutsanya. Nokudaro, gasi riri muforoma rinobudiswa nyore nyore. Kana mukati mechigadzirwa chakaputirwa mugasi (kuwedzera mukati), kana kana pane dents, hunyengeri husina maturo, iyi nzira inogona kugadziriswa. Yepakati jekiseni kumhanya kunofanirwa kushandiswa muSBS masisitimu. MuSEBS system, yekumhanyisa jekiseni yepamusoro inofanirwa kushandiswa. Kana mold iine yakakwana exhaust system, kunyangwe jekiseni rinomhanya-mhanya harifanirwe kunetseka nezvemhepo yakavharirwa.
5. Ngwarira kudzora kupisa kwekugadzirisa.
Iyo tembiricha yekugadzirisa yeTPE mbishi zvinhu ingangoita 200 madhigirii, uye TPE haitore hunyoro mumhepo panguva yekuchengetedza, uye kazhinji hapana nzira yekuomesa inodiwa. Bika pakupisa kukuru kwemaawa maviri kusvika mana. TPE yakavharidzirwa ABS, AS, PS, PC, PP, PA uye zvimwe zvinhu zvinoda kufanobikwa uye kubikwa pa80 degrees kwemaawa maviri kusvika mana.
Muchidimbu, ndiyo TPE raw material jekiseni molding process zvinodiwa. TPE raw material chinhu chinoshandiswa zvakanyanya thermoplastic elastomer material, inogona kuumbwa yega kana thermally bonded nePP, PE, ABS, PC, PMMA, PBT uye zvimwe zvinhu zvekuumba sekondari jekiseni, uye zvinhu zvacho zvinogona kushandiswazve. Yakachengeteka uye ine ushamwari kwezvakatipoteredza, yakatove chizvarwa chitsva cheakakurumbira rabha uye epurasitiki zvinhu.
