Iprofayile ye-PREX

I-HonyPro ® Polythyethylene i-Pesfaillies yi-thermoplastics ye-thermoplastics, engenanto, engenabungozi, i-onneble enetyhefu, i-whine enetyhefu, enokutsha, engenabungozi. I-ressins ye-PEED ye-PE ikhutshiwe kwaye i-vellets ye-waxy ene-waxy enembonakalo emhlophe ye-milky. Ubunzima bayo bemolekyuli bukuluhlu lwe-10,000 ukuya kwi-100,000.

Abo banobunzima obungaphezulu kwe-100,000 yi-Ultra-right molethylene. Ukuphakama ubunzima bemolekyuli, ezona zinto zingcono ngokwasemzimbeni kunye noomatshini, kunye nokusondela kwinqanaba elifanelekileyo lezixhobo zobunjineli. Nangona kunjalo, ukuphakama kwesisindo semolekyuli, kokukhona kuya kuba nzima ngakumbi. Indawo yokunyibilika yePolythylene yi-100-130c, kunye nokuchaswa kobushushu obuphantsi kakhulu kuhle. Ingagcina iipropathi ezintle ngoomatshini nge-60 ° C, kodwa iqondo lokushisa liyi-80 ° 11 ° C.

Phantsi kwesenzo semozulu, ilanga kunye neoksijini, i-Polythylene iya kudala, iqhekeza, ibe yi-brittle okanye ichithwe, kwaye iphulukane neempawu zayo zoomatshini.

Xa kusenziwa ubushushu bokuyilwa, ngenxa ye-oxidation, ukunyibilikisa kuya kuncipha, ukungqinelana kunye neminyaka iya kuvela, ke ingqwalaselo kufuneka ihlawulwe kwinkqubo yokubumba kunye nokusebenzisa inkqubo okanye ukukhetha izinto okanye ukukhetha izinto. Kungenxa yokuba i-Polythylene inezi mpawu zilapha ngasentla kwaye kulula ukuyiqhubela phambili kwaye isebenze, ukuphinda kusetyenziswe i-polythylene kunexabiso eliphezulu kakhulu.

Iimeko eziphambili zokubumba iiprofayili ze-PE

Iqondo lokushisa le-cylinder: Ubushushu be-boarl buhlobe ikakhulu kukuxinana kwe-PE kunye nexabiso lokunyibilika. Ikwanxulumene nohlobo kunye nokusebenza kwamatshini wokuxhuzula inaliti kunye nobume benxalenye yeplastiki eyintloko.

Kuba i-Pe sisixhobo se-crystalline, imizila yekristale ifumana inani elithile lobushushu ngexesha lokunyibilika, ngoko ke ubushushu be-barrel bufanele bube yindawo yayo yokunyibilika. I-LDP, iqondo lobushushu le-barrel lilawulwa nge-140-200 ° C, kwaye amaqondo obushushu e-HDPE alawulwa nge-220 ° C, ixabiso elincinci lithathwa ngasemva kwe-barrel, kwaye elixabiso liphezulu lithathwa kwisiphelo sangaphambili .

Amaqondo obushushu abumba: Iqondo lobuncwa elibunjiweyo linempembelelo enkulu kwi-crystallization yecandelo leplastiki. Ubushushu obuphezulu obuxhaphakileyo bukhokelela ekuphenduleni ubume obuphezulu kunye namandla aphezulu, kodwa izinga le-shrinkige liyakonyuka. Ngokwesiqhelo, iqondo lobushushu le-LDP ilawulwa nge-30 ° C ukuya kwi-45 ° C, ngelixa iqondo lobushushu le-HDPE liphezulu nge-10 ° C ukuya kwi-20 ° C.

Uxinzelelo lokuBula: Ukonyusa uxinzelelo lwentsholongwane luyingenelo ekugcwalisweni kwezinto ezityhidiweyo. Kuba i-Pe inolwelo oluhle, ngaphandle kweemveliso ezixineneyo nezenziweyo, uxinzelelo olusezantsi lwenaliti kufuneka lukhethwe ngononophelo. Uxinzelelo lwenaliti ngokubanzi yi-50mpa. Ubume bulula. Kwizithuba ezikhulu zeplastiki ngasemva kodonga, uxinzelelo lwenaliti lunokubaphantsi, kwaye ngokuchaseneyo.

Ukomisa: AKUKHO BUNGOZI OKUFUNYANWEYO ukuba zigcinwe ngokufanelekileyo.
Ubushushu bokunyibilika: 220 ~ 260C. Ngezixhobo ezineemolekyu ezinkulu, uluhlu lobushushu olucetyiswayo luphakathi kwe-200 ne-250c.
Iqondo lobushushu: 50 ~ 95c. Amacandelo eplastiki anobukhulu obungezantsi kwe-6mm kufuneka asebenzise iqondo lobushushu eliphezulu, kunye neenxalenye zeplastiki ezinobushushu obungaphezulu kwe-6mm kufuneka basebenzise ubushushu obungaphantsi.
Amaqondo obushushu okupholisa amacandelo e-PE Cendows ahlawulwe ukunciphisa umahluko kwi-shrinkage. Kwimijikelezo yomjikelo ophezulu wokupowiti, itayitile yokupholisa akufuneki ibe ngaphantsi kwe-8mm kwaye kufuneka ibe ngaphakathi kwi-1.3D yendawo yokubumba (apho 'i-' D 'ngumjelo wesitayile sokupholisa).

I-Polythylene (i-PE) ixabisa indleko eziphantsi, iguquguqukayo, kwaye isebenza lula, yenza ukuba yenye yezona zinto zithandwayo ze-thermoplastic esebenzayo namhlanje. Njengeprofayili ethembekileyo yeplastiki, i-hony plastics isebenza nge-polyethylene emiselweyo kubandakanya i-HDPE, MDPO NE-LDP. Senza iiprofayili ezahlukeneyo zePolithylene ezikhutshelweyo kubandakanya ityhubhu, amajelo, izinto ezifanelekileyo kunye nezinye iinxalenye zesiko.
