Ulwazi oluSisiseko malunga neeNdidi eziNtathu ze-PE Material (II)

3. LLDPE

I-LLDPE ayinayo ityhefu, ayinancasa kwaye ayinavumba, kwaye ubuninzi bayo buphakathi kwe-0.915 kunye ne-0.935g/cm3.I-copolymer ye-ethylene kunye nenani elincinci le-high-grade α-olefin phantsi kwesenzo se-catalyst, eyenziwa yi-polymerized ngoxinzelelo oluphezulu okanye uxinzelelo oluphantsi.Ulwakhiwo lwemolekyuli ye-LLDPE eqhelekileyo ibonakaliswe ngumqolo wayo onomda onamasebe ambalwa okanye angekho amade, kodwa inamasebe amafutshane.Ukungabikho kwamasebe amade ekhonkco kwenza i-polymer ibe yikristale ngakumbi.

Xa kuthelekiswa ne-LDPE, i-LLDPE ineenzuzo zamandla aphezulu, ukuqina okuhle, ukuqina okuqinileyo, ukuxhathisa ubushushu kunye nokumelana nokubanda.

Shwankathela

Isishwankathelo, ezi zinto zintathu zingentla zidlala imisebenzi yazo ebalulekileyo kwiindidi ezahlukeneyo zeeprojekthi ezichasene ne-seepage.I-HDPE, i-LDPE kunye ne-LLDPE zonke zineendawo ezintle zokugquma, ezinobungqina bokufuma kunye ne-anti-seepage, kwaye iimpawu zazo ezingenayo ityhefu, ezingenancasa nezingenavumba zizenza zisetyenziswe ngokubanzi kwezolimo, i-aquaculture, amachibi okwenziwa, amadama, kunye nemilambo, kwaye iye yasebenza ngamandla. ikhuthazwe kwaye yaziwe yi-Fisheries Bureau yeSebe lezoLimo laseTshayina, iShanghai Academy yeSayensi yokuLoba, kunye neZiko loShishino lokuLoba kunye neZixhobo.

Kwimeko ephakathi ye-asidi eqinile, isiseko esomeleleyo, i-oxidant eyomeleleyo kunye ne-solvent ye-organic, izinto eziphathekayo ze-HDPE kunye ne-LLDPE zingasetyenziswa kakuhle kwaye zisetyenziswe, ngokukodwa iimpawu ze-HDPE ekuchaseni i-asidi eqinile, i-alkali, i-oxidation eqinile kunye ne-solvent organic.Inkalo iphezulu kakhulu kunezinye izinto ezimbini, ngoko ke i-HDPE i-anti-seepage kunye ne-anti-corrosion coil isetyenziswe ngokupheleleyo kumashishini okukhusela amachiza kunye nokusingqongileyo.

I-LDPE nayo ine-asidi elungileyo, i-alkali, iimpawu zesisombululo setyuwa, kwaye inokwandiswa okulungileyo, ukugquma kombane, ukuzinza kweekhemikhali, ukusebenza kwenkqubo kunye nokumelana nobushushu obuphantsi, ngoko isetyenziselwa ezolimo, i-aquaculture, ukupakisha, ngakumbi Isetyenziswa ngokubanzi kwipakethe yokushisa ephantsi. kunye nemathiriyeli yentambo.

Ioomatshini bokukhupha iiplastikieyenziwe yi-KHMC ikakhulu isebenzisa i-HDPE ekwenzeni intambo ye-monofilament.Intambo yeplastiki eyenziwe ngumatshini wethu inamandla aphezulu kunye nomgangatho omhle kakhulu.
