Ibanga lefilimu le-Polyethylene eliphansi le-2202TN26
I-Low density polyethylene (LDPE) iyinhlaka yokwenziwa ekhiqizwa yi-polymerization yengcindezi ephezulu ye-ethylene free radicals, ngakho-ke yaziwa nangokuthi i-polyethylene yokucindezela okuphezulu.I-LDPE izinzile kumakhemikhali.Inokumelana okuhle kwe-asidi (ngaphandle kwe-oxidizing acid eqinile), ukumelana ne-alkali, ukumelana nosawoti, ukusebenza kahle kakhulu kokufakwa kukagesi.I-steam permeability ephansi.I-LDPE inoketshezi oluhle nokusebenza kahle kokucubungula.Ifanele izinhlobo ezihlukahlukene zobuchwepheshe bokucubungula i-thermoplastic, njengokubunjwa komjovo, ukubunjwa kwe-extrusion, ukubunjwa kwe-blow, ukubunjwa kwe-roll, ukunamathela, ukugwebu, ukubunjwa okushisayo, ukushisa okushisayo kwe-spray, ukushisela okushisayo nokunye.
Isici
I-LDPE isiphenduke into eluhlaza embonini yokupakisha ngenxa yokusebenza kwayo okuhle kokubumba kanye nezindawo ezinhle zokubona, izakhiwo zemishini kanye nezakhiwo zokuvala ukushisa ngemuva kokwakhiwa kwefilimu.
Isicelo
I-LDPE(2102TN26) isetshenziselwa ifilimu yezolimo, ifilimu eshwabene, ifilimu esobala, ifilimu ye-laminate, ifilimu ye-co-extrusion multilayer kanye nokupakishwa kwezokwelapha, zonke izinhlobo zezikhwama, i-LLDPE admixture;Izinto ezijwayelekile zefilimu, ezifanele ukukhiqizwa kwefilimu yokupakisha ekhanyayo, ifilimu yokumboza ngezolimo nezinye eziqukethe i-ejenti eshelelayo, i-ejenti yokuvula, ingasetshenziswa njengefilimu ye-laminate, ifilimu yokupakisha ye-cryogenic nezikhwama zokuthenga nokunye ukupakishwa kwansuku zonke, ifilimu yezolimo (ifilimu elichithiwe) eliqukethe. i-ejenti eshelelayo, i-ejenti yokuvula, ingasetshenziswa njengokupakishwa kwansuku zonke okuqukethe i-ejenti eshelelayo, i-ejenti yokuvula, ukupakishwa kwansuku zonke ngaphandle kwe-ejenti yokuvula, Ingasetshenziselwa ifilimu yokupakisha yansuku zonke yefilimu yokupakisha esindayo, ifilimu eshwabene, ifilimu ebamba ukushisa kanye nezinto zekhebula zokubumba okuncane, ifilimu yezolimo, ukupakishwa okusindayo okuqukethe i-ejenti ebushelelezi, i-ejenti yokuvula, ingasetshenziselwa ukupakishwa kwansuku zonke kokukhipha amagwebu, ukubumba umjovo kanye nefilimu yokugwaza, ukubumba umjovo kanye nefilimu;I-ejenti yokuvula engu-607BW ngaphandle kwe-ejenti eshelelayo isetshenziselwa imikhiqizo emikhulu enogqinsi olungaphezu kuka-3mm, njengeziqukathi ezingaphezu kwamalitha ayi-10 kanye nenhloso evamile yefilimu kanye nemikhiqizo egwazayo yokumboza, ukumboza isikhwama sendwangu, njll.

Iphakheji, Isitoreji kanye Nezokuthutha
I-resin ihlanganiswe nezikhwama ze-polypropylene ezihlanganiswe nefilimu ngaphakathi.Isisindo esiphelele singama-25Kg/isikhwama.I-resin kufanele igcinwe endaweni yokugcina impahla, eyomile futhi kude nomlilo kanye nokukhanya kwelanga okuqondile.Akufanele inqwabelane endaweni evulekile.Ngesikhathi sokuthutha, umkhiqizo akufanele ubekwe elangeni elinamandla noma imvula futhi akufanele uhanjiswe kanye nesihlabathi, inhlabathi, izinsimbi ezilahliwe, amalahle noma ingilazi.Ukuhamba nezinto ezinobuthi, ezonakalisayo nezivuthayo akuvunyelwe ngokuphelele.
