I-PE: I-Polyethylene PE resin yinto engeyiyo ityhefu kunye nevumba elimhlophe okanye umgubo, onembonakalo emhlophe yobisi kunye nokuziva ngathi une-wax; Inokutsha, inesalathiso seoksijini esikwi-17.4% kuphela, umsi ophantsi kunye nokuvuza ngexesha lokutsha, tyheli kwilangatye nakwiblue ngaphantsi.
Iphunga leparafini; ukufakwa kwamanzi aphantsi (i-polyethyleneI-PE polyethylene PE iquletheInani elincinci leebhondi eziphindwe kabini kunye namaqela e-ether kwimolekyuli, ke ukumelana nemozulu kwe-PE akulunganga, ilanga kunye nemvula kuya kubangela ukuguga, kufuneka kongeze ii-antioxidants, izikhombisi ezikhanyayo ukuphucula uzinzo olushushu lwe-polyethylene PE kwirhasi engena kulungile, kwaye iqondo lobushushu lokubola linokufikelela kuma-300â „ƒ okanye nangaphezulu; kodwa xa iqondo lobushushu lidlula kuma-50â „he kwimo eshushu, ioksijini eshushu iya kubangela ukuthotywa, ngenxa yoko kufuneka kongezwe i-antioxidants ukuphucula. Umzekelo, i-antioxidant ephambili eyi-1010 kunye ne-antioxidant eyi-168 encedisayo; ukumelana nobushushu kwe-PE emoyeni akulunganga, kwaye kuya kuphucula ngokunyuka kobunzima beemolekyuli kunye ne-crystallinity; kodwa ukumelana nobushushu obusezantsi be-PE kulunge kakhulu, kunye nobushushu obuphantsi bokwamkela ubushushu apha ngezantsi -50â „ƒ, kunye nokwanda kobunzima beemolekyuli, elona lisezantsi linokufikelela -140â„ ƒ; ukuqhuba kwe-thermal kwe-PE kuphezulu, iHDPE> LLDPE> LDPE; ulungelelwaniso lomgama lwe-PE lukhulu, lolukhulu phakathi kweentlobo zeplastiki, kwaye liphezulu ukuya kuthi ga (20 ~ 24) × 10 -5 -5 K -1 -1, LDPE> LLDPE> HDPE.
1. Ubuninzi be-polyethylene LLDPE Ubuninzi obuphantsipolyethylene LLDPE: Ikhonkco leemolekyuli ze-polyethylene esezantsi-inamasebe amade kwaye amafutshane kunye ne-crystallinity ephantsi, ubunzima beemolekyuli ngokubanzi buyi-50,000 ukuya kwi-500,000, i-resin emhlophe emhlophe eqinileyo, engenayo ityhefu, indawo yokuthambisa esezantsi, ubhetyebhetye obuhle, ukumelana nefuthe, okuhle ukumelana nobushushu obuphantsi, kwaye kunokuba -60⃠„Ukusebenza -80â„ ƒ, usambathisa ombane ogqwesileyo.
2. I-LDPE inamandla amabi oomatshini, ukumelana nobushushu obuphantsi, ukunganyangeki koxinzelelo lwendalo, ukubambelela, kunye nokuprinteka, kwaye ifuna unyango lomphezulu ukuphucula ukusebenza kwayo. I-LDPE ukufakwa kwamanzi okuphantsi kakhulu, phantse akukho ukufunxwa kwamanzi, uzinzo lweekhemikhali oluhle kakhulu, ezinje ngokuzinza kwiiasidi, ialkali, iityiwa, kunye nokunyibilikiswa kwezinto eziphilayo. Ukungena okuphezulu kwi-carbon dioxide kunye nevumba lezinto eziphilayo, kodwa ukungavumeleki kakuhle kumphunga wamanzi nomoya. Kulula ukutshisa, Ukutsha kunevumba leparafini, kulula ukuthoba kunye nokutshintsha umbala phantsi kwentshukumo yelanga kunye nobushushu.
3. Ukuxinana okuphezulu kwe-polyethylene HDPE:Ubuninzi be-polyethylene HDPE: Yimbumba emhlophe eguqukayo emhlophe eqinileyo, inqanaba le-HDPE lelona lincinci, kwaye amandla emolekyuli axinekile aQokelelwe, ngoko ke uxinano luphezulu, i-crystallinity iphezulu. I-HDPE inokumelana nobushushu obuphezulu, ukumelana neoyile, ukuxhathisa ngomphunga kunye noxinzelelo lokusingqongileyo, ukuxhathisa ngombane, ukumelana nefuthe kunye nokumelana nokubanda. I-HDPE inamandla kwaye ukusebenza kokuguga kubhetele kune-PP, kwaye ubushushu obusebenzayo buphezulu kune-PVC kunye ne-LDPE. I-HDPE inamanzi amancinci kakhulu, inetyhefu, uzinzo lweekhemikhali oluhle kakhulu, kwaye ifilimu inokungena okuncinci kumphunga wamanzi nomoya.
