Indlela yokuthumela:Ukuthunyelwa ngomkhumbi
Ukubonisa umlingani
Incazelo yomkhiqizo (ngesiNgisi, okubandakanya izinto, usayizi, izici, imisebenzi, amapharamitha ezobuchwepheshe, inani elincane loku-oda, izimo ezisebenzayo, njll.):
1. Ifilimu nesikhwama esenziwe nge-low-density polyethylene (LDPE) esisetshenziswa emithini senziwa ikakhulukazi nge-low-density polyethylene (LDPE) resin njengempahla eluhlaza eyinhloko kuphela, ngaphandle kokungeza izithako ezinobungozi. Izimpahla ezisetshenzisiwe zihlangabezana namazinga kazwelonke ezinto zokupakisha imithi namazinga ahlobene ne-USP. Inqubo yokukhiqiza iqedwa endaweni yokusebenzela ehlanzekile engu-D noma ngaphezulu, futhi yenziwa ngezindlela ezifana nokudweba ifilimu, ukufaka izikhwama, nokupakisha. Kuyinto yokupakisha imithi engakwazi ukuthintana ngqo nemithi futhi inobumsulwa obuhle kwezempilo nokuzinza kwamakhemikhali. Ingasetshenziswa njengezikhwama eziyisicaba, izikhwama ezinqenqemeni ezigobile, izikhwama ezingadonsi ugesi, izikhwama eziyisikwele phansi, njll.
2. Yonke inqubo ikhiqizwa endaweni yokusebenzela ehlanzekile enokungcola okuncane kakhulu kwamaphakethe, ayinavungi, futhi ayinawo amanye amakhekhe, ihlangabezana nezidingo zokupakisha imithi ehlanzekile. Ukuguquguquka okuhle, ukumelana nokwelula, ukumelana nokubhoboza, akulula ukulimala, nokumelana kahle nokushayeka. Ukusebenza kokushisa okuvalayo kuzinzile, amandla okuvalwa aphezulu, futhi ukupakisha okuvalwe kahle kungafinyelelwa, kuvimbele ngempumelelo ukungcola kwangaphandle. Izakhiwo zamakhemikhali ezizinzile, akukho ukusabela kwamakhemikhali nezithako eziningi ezisebenzayo zemithi kanye nezingxenye ezibucayi, kuqinisekisa ikhwalithi yemithi ezinzile.
3. Ukubukeka: Ubuso buvulekile, umbala uhambisana, akukho zimbobo, amagwebu, izinto ezingcolile, noma ukunamathela, futhi ingxenye eshiswe ngayo ibhokisi iyisicaba; Amandla okwelula: izilinganiso ezijwayelekile ezihambelana nomugqa nokuhambelana nokuhambelana ≥ 10MPa; Ukwelula lapho kuphuka: ≥ 130% lapho ubukhulu bungaphansi noma bulingana no-0.05mm, ≥ 200% lapho ubukhulu bungaphezu kuka-0.05mm; Amandla okushisa okuvalayo: ≥ 7.0N/15mm, kuvalwe ngokuqinile ngaphandle kokuhoxa; Amandla okudlulisa umusi wamanzi: Kunokusebenza okuhle kokuvimbela umusi wamanzi, kuhlangabezana nezidingo zokuvimbela umswakama zemithi.

Izinzuzo zomkhiqizo (ngesiNgisi, njengezinzuzo zohlobo, umklamo wokubukeka, ikhwalithi, izinzuzo zamanani, inani elincane lokuhleleka, ukubonisana kwamahhala, izipho zokuphromotha, ukwamukela ukwenza ngokwezifiso, njll.):
1. Ukusebenzisa izinto zokusetshenziswa ezihlanzekile ze-LDPE ngaphandle kokungeza izithako eziyingozi; Ukukhiqizwa okuphelele kwendawo yokusebenzela ehlanzekile ye-D-grade kuhlangabezana namazinga okuhlanzeka, kunokuhambisana kahle nemithi, akukho ukuthuthelwa kwezinto eziyingozi, futhi kuhlangabezana nezidingo zokuhambisana zokuthintana ngqo nokupakishwa kwemithi.
2. Ukukhiqizwa okugcwele okuhlanzekile, okungenalo uthuli, iphunga, nezinto zangaphandle; Ukupakisha okuhlanzekile ngaphambi kokushiya ifektri kungasetshenziswa ngqo ukuthuthwa nokugcinwa kwesikhashana kwezinto zokusetshenziswa, izinto ezisetshenziswa phakathi, nemishini ehlanzekile, kuvimbela ngempumelelo ukungcola okungahlangene kumkhiqizo wokukhiqiza futhi kuvumelane nezidingo zokuphatha ze-GMP emisebenzini yemithi.
3. Ukwakheka kunwebeka, kumelana nokwelula, kumelana nokubhoboza, kumelana nokushayeka, futhi akulimazi kalula ngesikhathi sokugcinwa nokuthuthwa; Ukusebenza okuhle kokuvalwa ngokushisa, ukuvalwa okuqinile ngaphandle kokuvuza, kuvimba ngempumelelo umusi, uthuli, namagciwane, kunezici ezinhle zokuvimbela umswakama nothuli, kuqinisekisa ukuzinza kokugcinwa kwemithi.
4. Izinto zithambile, kulula ukuzipakisha nokuzivala, zilungele izinto zokupakisha ezisebenza ngesandla neze-automated; Izinhlobonhlobo eziningi, ubukhulu, nezitayela (amaphakethe ayisicaba, amaphakethe aneziphetho, amaphakethe ayisikwele) zingakwazi ukwenziwa ngokwezifiso ukuze kuhlangatshezwane nezidingo zezimo ezahlukene zokukhiqiza.
5. Kulula ukuyiphatha, kunciphisa isisindo sokuthutha nokuthatha indawo yokugcina; Izindleko zezinto zokusetshenziswa zilawuleka futhi inqubo yokukhiqiza ivuthiwe. Uma kuqhathaniswa nama-film ahlanganisiwe namabhokisi e-aluminum foil, konga kakhulu futhi kufanelekele ukupakisha kwesikhathi eside nokujikeleza kwezinto eziningi ezinkulu nezisizayo.
1. Ukusebenzisa izinto zokusetshenziswa ezihlanzekile ze-LDPE ngaphandle kokungeza izithako eziyingozi; Ukukhiqizwa okuphelele kwendawo yokusebenzela ehlanzekile ye-D-grade kuhlangabezana namazinga okuhlanzeka, kunokuhambisana kahle nemithi, akukho ukuthuthelwa kwezinto eziyingozi, futhi kuhlangabezana nezidingo zokuhambisana zokuthintana ngqo nokupakishwa kwemithi.
2. Ukukhiqizwa okugcwele okuhlanzekile, okungenalo uthuli, iphunga, nezinto zangaphandle; Ukupakisha okuhlanzekile ngaphambi kokushiya ifektri kungasetshenziswa ngqo ukuthuthwa nokugcinwa kwesikhashana kwezinto zokusetshenziswa, izinto ezisetshenziswa phakathi, nemishini ehlanzekile, kuvimbela ngempumelelo ukungcola okungahlangene kumkhiqizo wokukhiqiza futhi kuvumelane nezidingo zokuphatha ze-GMP emisebenzini yemithi.
3. Ukwakheka kunwebeka, kumelana nokwelula, kumelana nokubhoboza, kumelana nokushayeka, futhi akulimazi kalula ngesikhathi sokugcinwa nokuthuthwa; Ukusebenza okuhle kokuvalwa ngokushisa, ukuvalwa okuqinile ngaphandle kokuvuza, kuvimba ngempumelelo umusi, uthuli, namagciwane, kunezici ezinhle zokuvimbela umswakama nothuli, kuqinisekisa ukuzinza kokugcinwa kwemithi.
4. Izinto zithambile, kulula ukuzipakisha nokuzivala, zilungele izinto zokupakisha ezisebenza ngesandla neze-automated; Izinhlobonhlobo eziningi, ubukhulu, nezitayela (amaphakethe ayisicaba, amaphakethe aneziphetho, amaphakethe ayisikwele) zingakwazi ukwenziwa ngokwezifiso ukuze kuhlangatshezwane nezidingo zezimo ezahlukene zokukhiqiza.
