PE bhegi ibhegi rakajairika muhupenyu hwedu hwezuva nezuva, rinoshandiswa kune marudzi ese emichero nemiriwo kurongedza, mabhegi ekutenga, zvigadzirwa zvekurima zvekurima, nezvimwe. Kuita senge nyore bhagi refirimu repurasitiki rinogona kunge rakaoma zvakanyanya. PE bhegi yekugadzira maitiro inosanganisira epurasitiki zvimedu - kupisa kupisa kusanganiswa - extrusion kutambanudza - yemagetsi kurapwa -; PE bhegi rinonyanya kuita akati wandei ari pamusoro, akarerutswa mushure memaitiro matatu: kuvhuvhuta firimu ------ kudhinda ------ bag kugadzira.
PE bhegi kudhinda maitiro anofanirwa kutarisisa kune chii?
Polyethylene, yakanakisa yakaderera tembiricha kuramba (shandisa tembiricha kusvika -70 ~-100), kemikari kugadzikana, yakawanda asidhi uye alkali kukukurwa (ine oxidizing acid kusashivirira), isinganyunguriki mune zvakajairika zvinonyungudutsa pakamuri tembiricha, kunyura kwakaderera, kuita kwakanaka kwemagetsi ekudzivirira. Nekudaro, polyethylene inonzwa kushushikana kwezvakatipoteredza (kemikari uye mechanical chiito) uye urombo mukupisa kuchembera. Izvo zvinhu zve polyethylene zvinosiyana kubva kumarudzi kune marudzi, kunyanya zvichienderana nekugadzirwa kwema molecular uye density. Zvigadzirwa zvine density dzakasiyana (0.91-0.96 G/CM3) zvinogona kuwanikwa nenzira dzakasiyana dzekugadzira. Polyethylene inogona kugadzirwa neyakajairwa thermoplastic kugadzira nzira (ona Plastics processing).
Ndeapi manotsi ane chekuita nehurongwa zvakadzama pazasi?
Maitiro ekuridza firimu anofanirwa kutarisisa kune anotevera mapoinzi:
1. Raw material proportion: maererano nezvinodiwa zvakasiyana-siyana zvePE mabhegi, kugadzirirwa kwezvikamu zvakasiyana-siyana zvezvigadzirwa. Semuenzaniso: anti-static, anti-rust, kuderedza, magetsi conductivity, biodegradation uye zvimwe zvinodiwa, wedzera zvakasiyana-siyana zvekuwedzera zvinowedzera semuenzaniso: kushandisa tsvuku, dema, ruvara uye mamwe mavara, kuwedzera zvakasiyana-siyana zvemavara evhavha. Zvinoenderana nekujeka, kuoma, simba rekubvarura, vacuum kudhirowa uye zvimwe zvinodiwa, kutsiva akasiyana mabhureki kana mhando dzePE zvinhu. Semuenzaniso: maererano nezvinodiwa zvakakosha, simbisa zvinodiwa zvekujeka kwepamusoro, kubvarura kwakasimba, kuvhurika kwakanaka, kuitira kuti uchinje chikamu chemidziyo.
2.the process of blowing film printing, the need for electronic processing, panguva ino kubhadhara simba rekugadzirwa kwemagetsi, kuve nechokwadi chokuti PE drum material electronic processing simba (DAYIN) zvakakwana kuti zvive nechokwadi chekunamatira inki.
3.mukuputira firimu, maererano nezvinodiwa zvakakosha zvefirimu, kuzarura kamwe chete, kuzarura kaviri, kupeta, kukanganisa kwepamusoro, kukanganisa, kuwedzera uye mamwe maitiro.
PE bhegi kudhinda maitiro anofanirwa kutarisisa kune zvinotevera zvinhu:
1.printing inki: mvura-based inki, inokurumidza kuomeswa inki, inki isingaoneki, inki inoshandura ruvara, anti-counterfeiting inki, induction induction, conductive ink, low electronic ink, matte inki uye mamwe maitiro einki.
2. Kudhinda ndiro: maererano nezvinodiwa zvakanaka zvekudhinda zvinyorwa, gravure (plate yemhangura) kudhinda uye flexography (offset) kudhinda kunoshandiswa. Idzi nzira mbiri dzakasiyana dzekudhinda.
3. Maererano nekuoma kwezvinyorwa zvekudhinda uye kuoma kwemavara, sarudza nzira yekudhinda: monochrome kudhinda, monochrome kaviri-sided printing, single-sided color printing, kaviri-sided color printing.
4. Maererano nezvinodiwa zvakakosha zvekudhinda mapatani, maererano nemaitiro e-discoloration, anti-counterfeiting, magetsi conductivity, adhesives nezvimwe zvakadaro, sarudza inki yakasiyana kana additives.
