Blow Molding Materials

Kunshan blow molding process inotora akasiyana matekinoroji uye zvinhu, kunyanya kusanganisira zvinotevera:

Polyethylene (PE) Polyethylene ndiyo inonyanya kugadzirwa muindasitiri yemapurasitiki.Polyethylene is opaque kana translucent, light-weight crystalline plastic ine yakanakisa yakaderera tembiricha kuramba (minimum inoshanda tembiricha inogona kusvika -70 ~ -100 ℃), yakanaka magetsi ekudzivirira uye kugadzikana kwekemikari, uye inogona kushingirira akawanda acids uye alkalis corrosion, asi kwete kupisa. resistant.Polyethylene yakakodzera kugadzirwa nejekiseni molding, blow molding, extrusion molding uye dzimwe nzira.PE inogona kugoverwa mu: low density polyethylene LDPE;high density polyethylene HDPE;linear yakaderera density polyethylene LLDPE.

Polypropylene (PP) Polypropylene ndeye thermoplastic inowanikwa ne polymerization yepropylene.Kazhinji haina ruvara, inopenya yakasimba, haina kunhuwa uye isina chepfu, ine density ye0.90 ~ 0.919 g/cm.Ndiyo yakareruka zvakajairika-chinangwa plastiki ine zvakatanhamara zvakanakira.Iyo ine hunhu hwekupokana nekubika mumvura, kushomeka kwekudzivirira, simba, kuomarara uye kujeka zviri nani pane polyethylene, iyo yakashata irombo yakaderera tembiricha inokanganisa kuramba, nyore kuchembera, asi inogona kuvandudzwa nekugadzirisa uye kuwedzera kwekuwedzera.Kune nzira nhatu dzekugadzira dze polypropylene: slurry nzira, mvura yakawanda nzira uye gasi chikamu nzira.

Polyvinyl Chloride (PVC) Polyvinyl chloride ipurasitiki inowanikwa ne polymerizing vinyl chloride, uye kuoma kwayo kunogona kushandurwa zvakanyanya nekuwedzera mapurasitiki.Zvigadzirwa zvayo zvakaoma uye kunyange zvigadzirwa zvakapfava zvine huwandu hwakawanda hwekushandisa.Nzira dzekugadzira dzepolyvinyl chloride dzinosanganisira kumiswa kwepolymerization, emulsion polymerization uye bulk polymerization, nekumiswa kwepolymerization senzira huru.

Polystyrene (PS) General-chinangwa polystyrene ipolymer ye styrene, iyo inopenya muchitarisiko, asi ine dhizaini yekuve brittle.Naizvozvo, kukanganisa-resistant polystyrene (HTPS) inogona kugadzirwa nekuwedzera polybutadiene.Nzira huru dzekugadzira dzepolystyrene dzakawandisa polymerization, kumiswa polymerization uye mhinduro polymerization.Kunshan Zhida blow molding processing

ABS ABS resin chigadzirwa che co-polymerization ye matatu monomers e acrylonitrile-butadiene-styrene, inonzi ABS terpolymer.Pamusana pezvikamu zvakasiyana-siyana zvezvikamu zvayo A (acrylonitrile), B (butadiene) uye S (styrene) mukuumbwa, pamwe chete nekusiyana kwemaitiro ekugadzira, zvinhu zvepurasitiki iyi zvakasiyana zvikuru.ABS yakakodzera kuumbwa kwejekiseni uye extrusion process, saka kushandiswa kwayo kunonyanya kugadzira aya marudzi maviri ezvigadzirwa.

Kuvhuvhuta pressure:

Kugadzira zvakajairwa ABS resin blow molding zvigadzirwa, iyo yekufuridza inowanzoitika 0.4-0.6MPA.Kune ABS inoshandiswa kugadzira mapurasitiki einjiniya, senge ABS inodzivirira kupisa, PC/ABS alloy, fluidity yayo haina kunaka, uye kufefetera kunowanzosvika kupfuura 1MPA.Kune zvigadzirwa zvine maitiro akanaka pamusoro pepamusoro, kana chimiro chichidiwa kuti chive chakajeka, mhepo inoputika inofanirawo kuwedzerwa.Kune zvigadzirwa zvine yakakwira yepamusoro zvinodiwa, senge mapapiro akaumbwa-akaumbwa emota muswe, izvo zvinoda kunotevera kurapwa kwependi, zvigadzirwa zvinofanirwa kunge zviri padyo neforoma kuitira kuti idzokorore iyo yakakwenenzverwa mold pamusoro panguva yekuvhuvhuta, uye kuvhuvhuta kunoitwa. kazhinji inodiwa kusvika 1.5-2.0MPA.Shanghai blowing molding zvigadzirwa zvine nzvimbo yakakura, iyo yakanyanya kuomarara zvigadzirwa, uye kutetepa kwemadziro ukobvu, ndiko kukwirisa kufefetera, uye zvichipesana.Kufuridza kwepamusoro kunokonzeresa kupedzisa kwepamusoro uye kugadzikana kwedimensional.Panzvimbo inoshanda, uchishandisa yakakwira kuvhuvhuta kumanikidza, kugadzirisa maitiro kuchava nyore, uye zviri nyore kuwana zvigadzirwa zvine yepamusoro yepamusoro mhando.

Kunshan Zhida Plastic Products Co., Ltd. inogadzira yakatsaurirwa kusimudzira uye kugadzira zvigadzirwa zvekuputira.Iyo kambani inotengesa zvakasiyana siyana zvekuumba zvigadzirwa gore rose.Iyo kambani inotarisira vatengi vatsva uye vekare vanouya kuzobvunza uye kutenga nebasa remhando yepamusoro.
