Ungayikhetha njani ityhubhu yeplastiki yobuhle ekumgangatho ophezulu?

Ityhubhu yeplastiki yobuhle, le nto yokupakisha ilula kwaye ingabizi kakhulu ineendlela ezahlukeneyo zokusetyenziswa kwicandelo leekhemikhali zemihla ngemihla, kwaye ithandwa kakhulu. Igqibelele kakhulu ityhubhu yeplastiki yobuhleAyinakukhusela kuphela umxholo, kodwa ikwaphucula nenqanaba lemveliso, ukuze iphumelele abathengi abaninzi kwiinkampani zeekhemikhali zemihla ngemihla. Ke ngoko, kwiinkampani zeekhemikhali zemihla ngemihla, ungazikhetha njani iityhubhu zeplastiki ze-osmetic ezikumgangatho ophezulu ezilungelelanisa neemveliso zazo? Ngezantsi siza kwazisa kwiinkalo ezininzi ezibalulekileyo.

Ukuqina kwezinto: Iinkampani zeekhemikhali zemihla ngemihla zineemfuno ezahlukeneyo ityhubhu yeplastiki yobuhleukuqina, ngoko ke ungakufumana njani ukuqina okufunekayo? I-polyethylene esetyenziswa kakhulu kwi ityhubhu yeplastiki yobuhles ikakhulu yi-polyethylene enoxinano oluphantsi, i-polyethylene enoxinano oluphezulu, kunye ne-polyethylene enoxinano oluphantsi oluthe ngqo. Ukuqina kwe-polyethylene enoxinano oluphezulu kungcono kunokwe-polyethylene enoxinano oluphantsi, ngoko ke ukuqina okufunekayo kunokufezekiswa ngokulungelelanisa umlinganiselo we-polyethylene enoxinano oluphezulu/i-polyethylene enoxinano oluphantsi.

Ukumelana neekhemikhali kwezinto: i-polyethylene enoxinano oluphezulu inokumelana neekhemikhali okungcono kune-polyethylene enoxinano oluphantsi.

Ukuguquguquka kwemozulu kwezinto: Ukulawula ukusebenza kwexesha elifutshane okanye elide kwe ityhubhu yeplastiki yobuhle, kufuneka uqwalasele: inkangeleko, ukumelana noxinzelelo/nokuwa, amandla okutywina, ukumelana nokuqhekeka koxinzelelo lokusingqongileyo (ixabiso le-ESCR), ivumba elimnandi kunye nokulahleka kwezithako ezisebenzayo.

Ukukhetha iMasterbatch: iMasterbatch idlala indima ebalulekileyo ityhubhu yeplastiki yobuhleulawulo lomgangatho. Ke ngoko, xa ukhetha i-masterbatch, ishishini lomsebenzisi kufuneka liqwalasele ukuba ingaba isasazeke kakuhle na, ihluziwe kwaye izinzile kubushushu, imelana nemozulu kwaye imelana nemveliso. Phakathi kwazo, ukumelana nemveliso ye-masterbatch kubaluleke kakhulu ekusebenziseni i-masterbatch. ityhubhu yeplastiki yobuhle, ukuba i-masterbatch ayihambelani nemveliso efakiweyo, umbala we-masterbatch uya kutshintshela kwimveliso, kwaye iziphumo zibi kakhulu. Ke ngoko, amashishini eekhemikhali emihla ngemihla kufuneka avavanye uzinzo lweemveliso ezintsha kunye ityhubhu yeplastiki yobuhles (yenza uvavanyo olukhawulezisiweyo phantsi kweemeko ezithile).

Iindidi zeoyile ekhazimlayo kunye neempawu zazo: ioyile ekhazimlayo esetyenziswa kwi ityhubhu yeplastiki yobuhleUhlobo lwe-ultraviolet UV kunye nohlobo lokomisa olushushu, olunokwahlulwa lube ngumphezulu okhanyayo kunye nomphezulu wenkungu ukusuka kwimbonakalo. Ioyile ekhazimlayo ayinakubonelela kuphela ngesiphumo esihle sokubonakala, kodwa ikwadlala indima ekukhuseleni umxholo, kwaye inefuthe elithile kwioksijini, umphunga wamanzi, kunye nomqobo wevumba. Ngokubanzi, uhlobo lokomisa olushushu lwe-gloss lunamathela kakuhle kwi-bronzing elandelayo kunye nokuprinta kwesikrini, kwaye i-ultraviolet UV gloss ine-gloss engcono. Amashishini eekhemikhali zemihla ngemihla anokukhetha ioyile ekhazimlayo efanelekileyo ngokweempawu zeemveliso zawo. Ukongeza, ioyile ekhazimlayo ephilisiweyo kufuneka ibe nokunamathela okuhle, umphezulu ogudileyo ongenamingxunya, ukumelana nokugoba, ukumelana nokuguguleka, ukumelana nokugqwala, kunye nokungabikho kombala ngexesha lokugcina.

Kukholelwa ukuba kwezi zinto zingasentla, uninzi lwamashishini eekhemikhali zemihla ngemihla kufuneka akwazi ukukhetha awona asemgangathweni ophezulu. ityhubhu yeplastiki yobuhleiimveliso zokupakisha.
