Ukuxinana polyethylene: yesicelo

Low polyethylene mninzi kuveliswe ukusuka ethylene nyulu, yaye njengento engundoqo organometallic ezivelileyo triethylaluminum kunye titanium tetrachloride. Kuba polyethylene kwi imboni yasekhaya isebenzisa ezahlukeneyo eziliqela kwezobuchwepheshe ezahluke uhlobo uyilo, umthamo reactor, iindlela nokucoca polyethylene kwi kuvala esetyenzisiweyo.

ubuchwepheshe

Amaninzi wazithwala ngaphandle amanyathelo ezintathu ezilandelelanayo: polymerization ethylene, ukuhlanjululwa salo ngumnxibelelanisi kunye inqubo yokoma yokugqibela. Emva ukukhwezela ngesisombululo triethylaluminum kunye titanium tetrachloride kwi cyclohexane esongezwa ipetroli. Ngumsindo 50 C-amabini ekhulwini isisombululo ukuze zixhase lo reactor, apho inkqubo air-lift ethylene longeziwe. Echukumisayo ikhuthaza yinxalenye ngobuninzi ethylene ukuya polyethylene polymerization.

Ukususa yempela ukusuka Polymer yahlaliswa ecociweyo off iimveliso ukucazululwa lichithakale. Le icentrifuge polyethylene wahlamba ukusuka iza kusetyenziswa methanol.

Polyethylene of koxinzelelo eliphantsi emva ngamanzi iphendukile phandle, kunye noko adityaniswe into ngenxa yokuphucula umgangatho. Ukucaciselwa somfanekiso ezisetyenziswayo, ethylene ethers kesodiyam nitrophosphate, nokwenza kube shinier, elinewax isicelo.

Ekugqibeleni, polyethylene ufakwa omiswe kunye granulation. Polyethylene of koxinzelelo ephantsi oluvelayo ngokohlobo granules kunye nomgubo.

Imibhobho ezenziwe polyethylene loxinano eliphantsi

zisetyenziselwa ufakelo iinkqubo igesi, umjelo kunye namanzi.

Imibhobho elalenziwe indlela extrusion rhoqo. Njenge ekrwada ekuveliseni polyethylene kwi granules kuphuma eziphathekayo.

Ngokwezoqoqosho amazwe aphuhlileyo usebenzisa imibhobho ezinjalo phantse kuzo zonke iinkqubo.

Imibhobho iHDPE musa ngokungalunganga kuchaphazela umgangatho wamanzi, kuba iindonga lwangaphakathi irusi akuxhomekekanga endiyibumbileyo, eziqokelelweyo iityuwa kwezimbiwa.

polyethylene xi Low ifumene isicelo kwiinkqubo umjelo, ekubeni ukumelana nezinto ndlongondlongo kunye amaqondo aphezulu.

Imibhobho Gas kwakhona abonakaliswa kwaye bangalahlekelwa iipropati ukusebenza ixesha elide.

Iyahlala - imibhobho ekumgangatho ophezulu ukusuka iHDPE. Yokuba yokothuka ezingatshiyo, musa ibole kwaye musa namhlwa, musa ngothanda phantsi kwempembelelo phezulu kunye namaqondo asezantsi. ubomi babo nkonzo iminyaka eliqela.

Polyethylene xi High ezithambileyo kwaye elastic. elakho lilungiselelo ezincinane ngokwentelekiso molecule ngokuyintloko kuchaphazela mninzi yayo. LDPE bavelise uluhlu olubanzi bhanya-bhanya. Zinelungelo kwizinga eliphezulu kakhulu, kwaye ukhetho impahla engcono, mhlawumbi ukuba kufunyanwa. Ilondoloza, umxhasi isethi iipropati esihle ngisho kwiqondo lobushushu iqondo amathandathu. iimpawu lomgangatho polyethylene musa ukutshintsha phantsi kwempembelelo kweekhemikhali. Yena uyakwazi ngokuthembekileyo womvalela imveliso evela ukufuma kunye nomphunga wamanzi.
