Izinto zePlastiki eziqhelekileyo ezisetyenziswa kwi-Extrusion kunye neePropati zazo

Ukukhetha iplastiki efanelekileyo yenye yezona zigqibo ezibaluleke kakhulu kwinkqubo ye-extrusion. Ukusuka kwingqibelelo yolwakhiwo ukuya ekucaceni okubonakalayo, imathiriyeli oyikhethayo inefuthe elithe ngqo ekusebenzeni kunye nobomi bemveliso yakho yokugqibela. Ukuqonda umahluko ophambili phakathi kwezixhobo zeplastiki eziqhelekileyo ze-extrusion kunokunceda abavelisi benze ukhetho olunolwazi, oluchanekileyo.

Makhe sihlolisise iimpawu eziphambili, iimfuno zokucubungula, kunye neziphumo zokugqibela zokusetyenziswa kweeplastiki eziqhelekileyo ezisetyenziswa kwi-extrusion.

I-PVC: I-Versatility idibana noKuchasana kweMichiza

I-Polyvinyl chloride (PVC) isetyenziswa ngokubanzi ngenxa yokulungelelana kwayo okugqwesileyo kweendleko, ukuqhubekeka, kunye nokuqina. Ifumaneka kwiifom eziqinileyo kunye neziguquguqukayo, i-PVC iyaxhathisa kwiikhemikhali, ukuvezwa kwe-UV, kunye nokufuma, iyenza ilungele imibhobho, iiprofayili, kunye nosetyenziso lwangaphandle.

Kwi-extrusion, iPVC iqhele ukusebenza phakathi kwe-160°C kunye ne-210°C. Ifuna iprofayili yobushushu elawulwa ngononophelo kunye noyilo lwe-screw oluxhasa ukunyibilika okuzinzileyo kwaye luthintele ukuthotywa. Ubume bayo bokubuyiswa komlilo kunye neempawu ezilungileyo zokugquma ziyenza ibe yeyona nto iphambili kusetyenziso lombane.

I-PE: Ikhaphukhaphu kunye ne-Impact-Resistant

I-Polyethylene (PE), ngakumbi kwiintlobo zayo ze-HDPE kunye ne-LDPE, yaziwa ngokuguquguquka kwayo, ukuxhathisa impembelelo, kunye nokufunxa okuphantsi komswakama. Yimathiriyeli yokuya kwityhubhu, iifilimu zokupakisha, kunye nemibhobho yamanzi.

I-PE ikhupha kakuhle kwi-160-230 ° C, kunye noyilo lwe-screw olugxininisa ukucheba okuphantsi kunye nokuphuma okuphezulu. Ukugqiba kwayo okugudileyo kunye nokumelana neekhemikhali okugqwesileyo kuyenza ilungele ukuthuthwa kolwelo kunye nokusetyenziswa koqhagamshelwano lokutya. Phakathi kwazo zonke izinto zeplastiki ze-extrusion, i-PE ibalasele ngokuqina kwayo okugqwesileyo kwiindawo ezinzima.

I-PP: Ukuzinza kweeKhemikhali kunye noBungqongqo

I-Polypropylene (PP) inika indibaniselwano ekhethekileyo yokuqina kunye nokumelana neekhemikhali. Inendawo yokunyibilika ephezulu kune-PE kwaye ibonelela ngokumelana nokudinwa okuphezulu, iyenza ifaneleke iindawo zemoto, izixhobo zelabhoratri, kunye neehenjisi zokuhlala.

Iinkqubo zePP kumaqondo obushushu aphezulu kancinci (200-280 ° C), kwaye ifuna isikrufu esinokuxuba okuqinileyo kunye neendawo zoxinzelelo ukuze kuqinisekiswe ukunyibilika okufanayo. Ikwakhaphukhaphu kwaye inokumelana kakuhle neeasidi kunye neziseko, ilungele indawo apho ukuvezwa kweekhemikhali kuxhaphakile.

I-ABS: Ukuqina ngoMgangatho wokuGqibela umphezulu

I-Acrylonitrile Butadiene Styrene (ABS) ikhethwa xa ukuchasana kwempembelelo kunye nokubonakala komphezulu ziimfuno eziphambili. Ngokuqhelekileyo ifumaneka kwiimpahla zabathengi kunye nezindlu ze-elektroniki, i-ABS idibanisa ukuqina kunye nokuzinza okuhle kwe-dimensional.

Ukukhupha i-ABS kufuna amaqondo obushushu kuluhlu lwe-190–240°C, kunye ne-moderate screw shear ukuphepha ukutyheli okanye iziphene zomhlaba. Ngelixa i-ABS ingaxhathisi kwi-UV ngaphandle kwezongezo, umlinganiselo wayo wokuqina ukuya kubunzima buyenza idume kwizicelo ezisebenza kakhulu.

I-PC: Ukucaca kwe-Optical kunye nokumelana nobushushu

I-Polycarbonate (i-PC) ikhethwa ngenxa yokungafihli, ukuzinza kwe-thermal, kunye namandla empembelelo ephezulu. Ihlala isetyenziswa kwizigqubuthelo zokukhanyisa, iiphaneli zokhuselo, kunye nezixhobo zonyango apho ukucaca kunye nokomelela ziyimfuneko zombini.

I-PC extrusion ifuna amaqondo obushushu phakathi kwe-240-300 ° C kunye ne-screw ye-torque ephezulu ye-extruder ene-shear elawulwayo. Phakathi kwezixhobo zeplastiki ze-extrusion, i-PC idinga ulawulo oluchanekileyo lobushushu ukunqanda ukutyheli okanye ukonakala. Ukucaca kwayo okubonakalayo kwenza kube yinto ekhethekileyo yokukhethwa kwezicelo ezifuna ukubonakala okuphezulu kunye nokuhanjiswa kokukhanya.

Ukuthelekisa izinto eziphathekayo kwiSicelo: Isitshixo seMpumelelo

Ukukhetha imathiriyeli yeplastiki echanekileyo ye-extrusion ayikho nje malunga neendleko okanye ukufumaneka-kumalunga nokulungelelanisa iimpawu zokusebenza kunye neemfuno zesicelo. Ngaba ufuna ukuxhathisa okuphezulu kwe-UV kusetyenziso lwangaphandle? I-PVC okanye i-PE eyenziwe ngokukodwa inokuba yeyona nto ingcono. Ngaba ujonge iipaneli ezicacileyo, ezihlala ixesha elide? Cinga ngePC. Kwizikhongozeli ezikwaziyo ukumelana neekhemikhali, iPP ngoyena mdlali uphezulu.

Izinto zeplastiki ze-extrusion ozikhethayo aziyi kugqiba ukukhululeka kokulungiswa kodwa kunye nempumelelo yexesha elide yemveliso yakho kwintsimi.

Ngaba ujonge ukwandisa umgca wakho we-extrusion ngezinto ezifanelekileyo zeplastiki? Qhagamshelana neJWELLnamhlanje-iqabane lakho othembekileyo kwizisombululo extrusion eziphambili kunye nobuchule izinto.
