Yintoni iPolyethylene yoXinano oluPhezulu

I-polyethylene ephezulu (HDPE), ipowder emhlophe okanye imveliso yegranular. I-non-toxic, incasa, i-crystallinity ye-80% ukuya kwi-90%, indawo yokuthambisa ye-125 ukuya kwi-135 ° C, sebenzisa ubushushu ukuya kwi-100 ° C; ukuqina, amandla okuqina kunye ne-ductility kungcono kune-polyethylene ephantsi yoxinaniso; Ukumelana nokunxiba, umbane Ukugquma okulungileyo, ukuqina kunye nokumelana nokubanda; Uzinzo oluhle lweekhemikhali, olungenakunyibilika kuyo nayiphi na i-solvent ye-organic kwiqondo lokushisa, ukuxhatshazwa kwe-corrosion ye-asidi, i-alkali kunye neetyuwa ezahlukeneyo; ifilimu encinci ukufikeleleka kumphunga wamanzi kunye nomoya, ukufunxa kwamanzi okuphantsi; ukunganyangeki ukuguga, ukunyanzeliswa koxinzelelo lokusingqongileyo akulunganga njenge-polyethylene yoxinaniso oluphantsi, ngakumbi i-oxidation ye-thermal iya kunciphisa ukusebenza kwayo, ngoko ke i-antioxidants kunye ne-ultraviolet absorbers kufuneka yongezwe kwi-resin ukuphucula le ntsilelo. Ifilimu ye-polyethylene ene-high-density inobushushu obuphantsi bokuphazamisa ukushisa phantsi koxinzelelo, ngoko ke yithathele ingqalelo xa uyisebenzisa.

[Igama lesiNgesi] I-Polyethylene yoXinano oluPhezulu
[isishunqulelo sesiNgesi] HDPE
[Igama eliqhelekileyo] Uxinzelelo oluphantsi lwe-ethylene
[I-monomer yokwakhiwa] I-Ethylene

[Iimpawu ezisisiseko] I-HDPE yinto emhlophe e-opaque efana ne-wax kunye ne-gravity ethile elula kunamanzi, kunye ne-gravity ethile ye-0.941 ~ 0.960. Ithambile kwaye yomelele, kodwa iqina kancinci kune-LDPE, kwaye iyanwebeka kancinane, ayinatyhefu kwaye ayinancasa.

[Iimpawu zokutsha] Iyatsha kwaye ingaqhubeka nokuvutha emva kokushiya umlilo. Isiphelo esiphezulu sedangatye sityheli kwaye isiphelo esisezantsi sibhlowu. Xa kutshisa, kuya kunyibilika, kuya kubakho ukuvuza kwamanzi, kwaye akukho msi omnyama uya kuvela. Kwangaxeshanye, ikhupha ivumba lokutsha kweparafini.

[Iinzuzo eziphambili] Ukumelana ne-Acid kunye ne-alkali, ukuxhathisa kwe-solvent ye-organic, ukugquma kombane okugqwesileyo, kwaye kusenokugcina ukuqina okuthile kubushushu obuphantsi. Ukuqina komphezulu, amandla okuqina, ukuqina kunye namanye amandla omatshini aphezulu kune-LDPE, kufutshane nePP, yomelele kunePP, kodwa ukugqitywa komphezulu akulunganga njengePP.

[Izinto ezingeloncedo eziphambili] Iipropathi ezingalunganga zoomatshini, ukungena komoya kakubi, ukuguquka lula, ukuguga kulula, ukuba brittle, ukonakala kancinci kunePP, kulula ukucinezela ukuqhekeka, ubulukhuni obusezantsi, kulula ukukrwela. Kunzima ukuprinta, xa kuprintwa, kufuneka unyango lokukhutshwa komphezulu, akukho electroplating, kwaye umphezulu uyabuthuntu.

[Izicelo] Isetyenziselwa iifilimu zokupakisha ze-extrusion, iintambo, iingxowa ezilukiweyo, iminatha yokuloba, imibhobho yamanzi; ukubunjwa kwesitofu sezinto eziyimfuneko zemihla ngemihla kunye namaqokobhe asezantsi, amacandelo angathwali mthwalo, iibhokisi zeplastiki, iibhokisi zentengiso; izikhongozeli zokubumba ze-extrusion, iimveliso ezingenanto, iibhotile.
