Tembiricha muganho wePE inodzivirira firimu

Pe inodzivirira firimu tembiricha, inoshandiswa zvakanyanya muhupenyu, zvakare yakajairika mukutakura kwechinyakare, indasitiri yechikafu, uye indasitiri yekurapa. Huwandu hukuru hwekurongedza hwakashandiswa kare pane zvakatipoteredza hunosvibisa zvakanyanya. Hupenyu iko kushandiswa kwePE inodzivirira firimu rekudya kurongedza kutsva; PE inodzivirira firimu zvakare kazhinji mune mbiri tembiricha nyika: yakaderera tembiricha, tembiricha yepamusoro, uye yakaderera tembiricha.

PE inodzivirira firimu, Zita rakazara Polyethylene, ndicho chimiro chezvakareruka zvepolymer organic komisheni, inonyanya kushandiswa pasi rose zvinhu zvepolymer. Zvinoenderana neakasiyana densities, PE inodzivirira firimu uye yakakosha polyethylene (PE) yepurasitiki firimu se substrate yakakamurwa kuita yakakwirira-density polyethylene inodzivirira firimu, yepakati-density polyethylene, uye yakaderera-density polyethylene.

PE inogona kukamurwa kuva LDPE (yakaderera-density polyethylene) uye HDPE (yakakwirira-density polyethylene) .LDPE ine inoenderera kushandiswa tembiricha 60-80 ℃, uye HDPE ane nguva dzose kushandiswa tembiricha 80-100 ℃. Kupisa kwayo kwepamusoro-soro kunogona kusvika ku100 degrees Celsius.

Tianrun yagara ichiisa kukosha kukuru pakuchengetedzwa kwezvakatipoteredza uye kusimudzira kwakasimba. Isu tinoshingairira kukurudzira kushandiswa kwezvinhu zvinoparara uye zvinodzokororwa uye tinoedza kuderedza kusvibiswa nemarara panguva yekugadzira. Isu tiri A-level kuchengetedza nharaunda bhizinesi muChina. Kugona kwedu kwakanakisa kuchengetedza kwezvakatipoteredza kunogona kuve nechokwadi kutumirwa kwakajairwa kwemirairo pasi pemamiriro ezvirambidzo zvekugadzira zvakatemerwa nezviremera.
