Ulwazi Oluyisisekelo Ngezinhlobo Ezintathu Zezinto Ze-PE (II)

3. LLDPE

I-LLDPE ayinabo ubuthi, ayinambitheki futhi ayinaphunga, futhi ukuminyana kwayo kuphakathi kuka-0.915 no-0.935g/cm3.I-copolymer ye-ethylene kanye nenani elincane le-α-olefin ephezulu yezinga eliphezulu ngaphansi kwesenzo se-catalyst, eyenziwa nge-polymerized ngokucindezela okukhulu noma ukucindezela okuphansi.Isakhiwo samangqamuzana e-LLDPE evamile sibonakala ngomgogodla wayo oqondile onamagatsha ambalwa noma angekho amade, kodwa iqukethe amagatsha amafushane.Ukungabikho kwamagatsha amaketango amade kwenza i-polymer ibe crystalline kakhulu.

Uma kuqhathaniswa ne-LDPE, i-LLDPE inezinzuzo zamandla aphezulu, ukuqina okuhle, ukuqina okuqinile, ukumelana nokushisa nokumelana nokubanda.

Fingqa

Kafushane, lezi zinto ezintathu ezingenhla zidlala imisebenzi yazo ebalulekile ezinhlotsheni ezihlukene zamaphrojekthi aphikisana nokuphenya.I-HDPE, i-LDPE kanye ne-LLDPE zonke zinezindawo zokuvikela umswakama ezinhle, ezivikela umswakama kanye nezindawo zokunqanda ukubola, futhi izakhiwo zazo ezingenabuthi, ezinganambitheki futhi ezingenaphunga zizenza zisetshenziswe kabanzi kwezolimo, ukulima kwezilwane zasemanzini, amachibi okwenziwa, amadamu, kanye nemifula, futhi ibilokhu isetshenziswa ngamandla. okugqugquzelwe futhi kwaduma i-Fisheries Bureau yoMnyango Wezolimo wase-China, i-Shanghai Academy of Fishery Sciences, kanye ne-Institute of Fisheries Machinery and Anstruments.

Endaweni ephakathi ye-asidi eqinile, isisekelo esiqinile, i-oxidant eqinile kanye ne-solvent ye-organic, izakhiwo ezibonakalayo ze-HDPE ne-LLDPE zingasetshenziswa kahle futhi zisetshenziswe, ikakhulukazi izakhiwo ze-HDPE ekumelaneni ne-asidi eqinile, i-alkali, i-oxidation eqinile kanye ne-organic solvent.Isici siphakeme kakhulu kunezinye izinto ezimbili, ngakho-ke ikhoyili ye-HDPE evimbela ukubola kanye ne-anti-corrosion isetshenziswe ngokugcwele ezimbonini zamakhemikhali nezokuvikela imvelo.

I-LDPE iphinde ibe ne-asidi enhle, i-alkali, izici zesixazululo sikasawoti, futhi inokunwebeka okuhle, ukwahlukanisa kagesi, ukuzinza kwamakhemikhali, ukusebenza kokucubungula nokumelana nokushisa okuphansi, ngakho-ke isetshenziswa kwezolimo, ukulima, ukupakisha, ikakhulukazi Isetshenziswa kabanzi ekufakweni kwamazinga okushisa aphansi. nezinto zekhebula.

Iimishini yokukhipha ipulasitikieyenziwe yi-KHMC ikakhulukazi isebenzisa i-HDPE ekwenzeni izintambo ze-monofilament.Intambo yepulasitiki eyenziwe umshini wethu inamandla aphezulu futhi ikhwalithi enhle kakhulu.
