Yakaderera density polyethylene yekuputika-yakaumbwa firimu,
LDPE firimu giredhi, ldpe yekugadzira mafirimu,

Low-density polyethylene (LDPE) is a synthetic resin inoshandisa high pressure process kuburikidza nemahara radical polymerization ye ethylene uye nekudaro inonziwo "high-pressure polyethylene".Sezvo cheni yayo yemamorekuru ine matavi mazhinji marefu uye mapfupi, LDPE haina crystalline pane yakakwirira-density polyethylene (HDPE) uye density yayo yakaderera.Inoratidzira chiedza, inoshanduka, yakanaka yekudzivirira kutonhora uye kukanganisa kwekudzivirira.LDPE yakagadzikana mumakemikari.Iine kumira kwakanaka kune acids (kunze kweiyo yakasimba oxidizing acids), alkali, munyu, yakanakisa magetsi ekudzivirira zvinhu.Kupinda kwayo kwemhute kwakaderera.LDPE ine yakakwira fluidity uye yakanaka processability.Yakakodzera kushandiswa mumhando dzese dze thermoplastic processing process, senge jekiseni rekugadzira, extrusion molding, blow molding, rotomolding, coating, foaming, thermoforming, hot-jet welding uye thermal welding.

Application

LDPE inonyanya kushandiswa kugadzira mafirimu.Inoshandiswa zvakanyanya mukugadzira firimu rekurima (mulching firimu uye yakadururwa firimu), yekurongedza firimu (yekushandisa mukutakura zvihwitsi, miriwo uye chikafu chakaomeswa), firimu rinopeperetswa rekurongedza mvura (yekushandisa mukurongedza mukaka, soy muto, muto, bhinzi nemukaka wesoya), mabhegi ekurongedza anorema, shrinkage yekurongedza firimu, elastic firimu, lining firimu, firimu rekuvaka, general-chinangwa maindasitiri ekurongedza firimu uye mabhegi ezvekudya.

LDPE inoshandiswawo zvakanyanya mukugadzira waya & tambo yekumisa sheath.Muchinjikwa-yakabatana LDPE ndicho chinhu chikuru chinoshandiswa mune yekuvharisa layer yeakakwira-voltage tambo.

LDPE inoshandiswawo mukugadzira zvigadzirwa zvakaumbwa nejekiseni (zvakadai semaruva ekugadzira, zviridzwa zvekurapa, mushonga uye zvinhu zvekurongedza zvekudya) uye machubhu akaumbwa, mahwendefa, waya & tambo dzekupotera uye zvigadzirwa zvepurasitiki zvakadhindwa.

LDPE inoshandiswawo kugadzira zvigadzirwa zvakaputirwa nemhepo zvakaita semidziyo yekubata chikafu, mushonga, zvekuzora uye zvigadzirwa zvemakemikari, uye matangi.

Package, Kuchengeta uye Kutakura

Sarudzo ye polyethylene inoputika-yakaumbwa firimu zvinhu

1. Izvo zvakasarudzwa zvekushandisa zvinofanirwa kupeperetswa firimu giredhi polyethylene resin zvimedu, zvine huwandu hwakakodzera hwekutsvedza agent,

Iva nechokwadi chekuvhurwa kwefirimu.

2 resin particle melt index (MI) haigone kuve yakakura, melt index (MI) yakakura kwazvo, yobva yanyungudutsa resin.

Iyo viscosity idiki zvakanyanya, iyo yekugadziridza mhando yakamanikana, mamiriro ekugadzirisa akaoma kudzora, iyo firimu inogadzira pfuma ye resin haina kunaka, haisi nyore.

Kugadzira mufirimu;Pamusoro pezvo, melt index (MI) yakakurisa, polymer hama molecular huremu kugovera yakatetepa, firimu rakatetepa

Murombo ane simba.Naizvozvo, diki melt index (MI) uye yakafara hama molecular uremu kugovera kunofanirwa kusarudzwa

Iyo haigone chete kusangana nekuita zvinodiwa zvefirimu, asi zvakare kuve nechokwadi chekugadzirisa maitiro eresin.

Blow yakaumbwa polyethylene firimu rinowanzo shandisa iyo melt index (MI) muhuwandu hwe2 ~ 6g/10min polyethylene.
