Iingcingo, iintambo, imibhobho, imibhobho, kunye neeprofayili zizicelo ezimbalwa kuphela zePE. Izicelo zemibhobho zisusela kwimibhobho emnyama enodonga olungqindilili oluyi-48-intshi ye-intshi yemizi-mveliso neyedolophu ukuya kwimibhobho emincinci etyheli enqamlezileyo yerhasi yendalo. Ukusetyenziswa kombhobho wodonga olunomngxuma omkhulu wedayamitha endaweni yemigca yogutyulo kunye nemijelo yesichotho eyenziwe ngekhonkrithi iyanda ngokukhawuleza.
Thermoforming kunye namaphepha
Uninzi lwezinto ezipholileyo zepikiniki ezinkulu ziquka ii-thermoformed liners ezenziwe nge-PE, ezinika ukuqina, ukukhanya, kunye nokuqina. Iifenda, iintambo zetanki, iipani zokugada, iikhreyiti zothutho, kunye neetanki ziyimizekelo yephepha elongezelelweyo kunye nezinto ezithermoformed. I-Mulch okanye i-pool bottoms, exhomekeke kukuqina kwe-MDPE, ukuxhathisa imichiza, kunye nokunganyanzeki, zizinto ezimbini ezibalulekileyo kwaye zikhula ngokukhawuleza izicelo zephepha.
Ukuvuthela iimbumba
IUnited States ithengisa ngaphezu kwesinye kwisithathu sayoHDPEyokubumba isivuthelo. Zisusela kwiifriji ezincinci, iifriji ezinkulu, iitanki zamafutha emoto, kunye neetoti ukuya kwiibhotile zeblitshi, ioli yemoto, into yokucoca, ubisi kunye namanzi amile. Amabakala afanayo angasetyenziselwa usetyenziso lwephepha kunye ne-thermoforming kuba amandla okunyibilika, i-ES-CR, kunye nokuqina ziziphawuli ezahlukeneyo zamabakala okubumba.
isitofu
Izikhongozeli ezincinci (ngaphantsi kwe-16oz) zihlala ziveliswa kusetyenziswa ukubunjwa kokuvuthela ukupakishwa kweeshampu, izithambiso, kunye namayeza amiselweyo. Inzuzo yale ndlela kukuba iibhotile ezigqityiweyo zihlanjululwa ngokuzenzekelayo, ngokungafaniyo neenkqubo eziqhelekileyo zokubumba ezifuna imisebenzi emva kokugqiba. Nangona amanye amabakala emxinwa e-MWD esetyenziselwa ukomeleza umphezulu wepolishi, amabanga aphakathi ukuya kububanzi be-MWD aqhele ukusetyenziswa.
isitofu sokubumba
Isinye kwisihlanu semveliso eyenziwe ekhayaHDPEisetyenziswa kwizicelo eziqala kwi-5-gsl kwitoti ukuya kwiikomityi zesiselo eziphinda zisetyenziswe. Kukho amabakala asezantsi e-fluidity enobunzima kunye namabakala aphezulu e-fluidity kunye ne-machinability, kunye ne-injection yokubumba amabakala ngokuqhelekileyo anesalathisi sokunyibilika kwe-5 ukuya kwe-10. Iimpahla ezinqabileyo ezinodonga kunye nokupakishwa kokutya, ukutya okunzima, okuhlala ixesha elide kunye neetoti zepeyinti, kunye nezicelo ezinokumelana okungaqhelekanga nokuqhekeka koxinzelelo lokusingqongileyo, ezifana ne-90-gallon ye-gallon isebenzisa i-tank yenkunkuma yezinto eziphathekayo kule nto kunye ne-tiny.
ukuguqula ukubumba
Xa izinto zisetyenzwa kusetyenziswa le teknoloji, zidla ngokutyunyuzwa zibe ngumgubo kwaye zinyibilike kwaye zihamba kumjikelo we-thermal. I-Rotomolding isebenzisa iiklasi ze-PE ezixhamlayo kunye nenjongo ngokubanzi. Isalathiso sayo sokunyibilika ngokuqhelekileyo siqhuba ukusuka kwi-3 ukuya kwi-8, kunye noxinzelelo ngokubanzi lwe-MDPE/HDPEiqhele ukuba phakathi kwe-0.935 kunye ne-0.945g/CC ene-MWD emxinwa, inika imveliso impembelelo ephezulu kunye ne-warpage encinci. Amabanga aphezulu e-MI awafanelekanga ngenxa yokuba abanayo impembelelo ecetyiweyo yeempahla eziyenziwe nge-rotomold kunye nokumelana nokuqhekeka koxinzelelo lwendalo.
Izicelo ze-rotomoulding yokusebenza ephezulu zisebenzisa iimpawu ezikhethekileyo zamabakala ayo anokuqhambuka ngokwekhemikhali. La mabakala anokumelana noxinzelelo olubalaseleyo lokusingqongileyo kunye nokuqina ngexesha lenqanaba lokuqala lomjikelo wokubumba xa zihamba kakuhle. ukumelana nemozulu kunye nokukrazula. Izikhongozeli ezinkulu ukusuka kwi-20,000-gallon yokugcina iitanki zezolimo ukuya kwi-500-gallon yokugcina iitanki ezisetyenziselwa ukuthwala iikhemikhali ezahlukeneyo zifaneleke ngokugqibeleleyo kwi-PE edibeneyo.
ifilimu
Ukusetyenzwa kwefilimu evuthelweyo eqhelekileyo okanye ukusetyenzwa kweflat extrusion ngokuqhelekileyo kusetyenziswa kwifilimu ye-PE. Uninzi lwee-PEs zisetyenziselwa iifilimu; iinketho ziquka i-linear low density PE (LLDPE) okanye i-general-purpose low density PE (LDPE). Xa ukunwebeka okukhulu kunye neempawu ezibalaseleyo zesithintelo zifuneka, amabakala efilimu yeHDPE asetyenziswa ngokuqhelekileyo. Umzekelo, ifilimu yeHDPE isetyenziswa rhoqo kwiibhegi zevenkile enkulu, ukupakishwa kokutya, kunye neengxowa zemveliso.
