Indlela yokukhetha ityhubhu yeplastiki yokuthambisa ekumgangatho ophezulu?

ityhubhu yeplastiki yokuthambisa, le nto yokupakisha efanelekileyo kunye neyoqoqosho inoluhlu olubanzi lwezicelo kwintsimi yeekhemikhali zemihla ngemihla, kwaye ithandwa kakhulu.ityhubhu yeplastiki yokuthambisaayikwazi ukukhusela imixholo kuphela, kodwa iphucule umgangatho wemveliso, ukuze uphumelele abathengi abaninzi kumashishini emichiza yemihla ngemihla. Ngoko ke, kumashishini emichiza yemihla ngemihla, indlela yokukhetha iityhubhu zeplastiki ze-osmetic ezikumgangatho ophezulu ezihambelana nemveliso yazo? Ngezantsi kwethu izakwazisa ngemiba emininzi ebalulekileyo.

Ukuqina kwezinto: Iinkampani zemichiza zemihla ngemihla zineemfuno ezahlukeneyo ze ityhubhu yeplastiki yokuthambisaukuqina, ngoko ungafumana njani ubunzima obufunwayo? I-polyethylene ngokuqhelekileyo isetyenziswaityhubhu yeplastiki yokuthambisasubukhulu becala yipolyethylene yoxinaniso olusezantsi, ipolyethylene yoxinaniso oluphezulu, kunye ne-linear low-density polyethylene. Ukuqina kwe-polyethylene yoxinaniso oluphezulu lungcono kune-polyethylene yoxinaniso oluphantsi, ngoko ke ubunzima obufunwayo bunokufezekiswa ngokulungelelanisa umlinganiselo we-polyethylene yoxinaniso oluphezulu / i-polyethylene ephantsi yoxinaniso.

Ukumelana nemichiza yezinto: i-polyethylene yoxinaniso oluphezulu inokumelana neekhemikhali ezingcono kune-polyethylene ephantsi.

Ubume bemozulu yezinto: Ukulawula ukusebenza kwexesha elifutshane okanye elide leityhubhu yeplastiki yokuthambisa, kufuneka uqwalasele: ukubonakala, ukunyanzeliswa kwengcinezelo / ukulahla, amandla okutywinwa, ukunyanzeliswa koxinzelelo lwendalo (ixabiso le-ESCR), i-fragrance kunye nokulahleka kwesithako esisebenzayo.

Ukukhetha i-Masterbatch: i-masterbatch idlala indima ebalulekileyoityhubhu yeplastiki yokuthambisaulawulo lwemeko. Ngoko ke, xa ukhetha i-masterbatch, ishishini lomsebenzisi kufuneka liqwalasele ukuba linokusasazeka kakuhle, ukuhluzwa kunye nokuzinza kwe-thermal, ukumelana nemozulu kunye nokuchasana kwemveliso. Phakathi kwabo, ukuchasana kwemveliso ye-masterbatch kubaluleke kakhulu ekusebenziseniityhubhu yeplastiki yokuthambisa, ukuba i-masterbatch ayihambelani nemveliso efakiweyo, umbala we-masterbatch uya kufudukela kwimveliso, kwaye iziphumo zinzima kakhulu. Ke ngoko, amashishini emichiza yemihla ngemihla kufuneka avavanye ukuzinza kweemveliso ezintsha kunyeityhubhu yeplastiki yokuthambisas(yenza iimvavanyo ezikhawulezayo phantsi kweemeko ezichaziweyo).

Iindidi zeoli yeglosi kunye neempawu zazo: ioli yeglosi esetyenzisiweyo kwiityhubhu yeplastiki yokuthambisaluhlobo lwe-UV ye-ultraviolet kunye nohlobo lokumisa okushushu, olunokwahlulwa lube ngumphezulu oqaqambileyo kunye nomphezulu wenkungu ukusuka kwinkangeleko. Ioli ye-gloss ayikwazi ukubonelela kuphela umphumo obonakalayo omhle, kodwa iphinde idlale indima ekukhuseleni umxholo, kwaye inefuthe elithile kwi-oksijeni, umphunga wamanzi, umqobo wevumba. Ngokubanzi, uhlobo lokumisa okutshisayo lweglosi lunokunamathela kakuhle kwi-bronzing elandelayo kunye nokuprintwa kwesikrini, kunye neglosi ye-ultraviolet ye-UV ineglosi engcono. Amashishini amachiza emihla ngemihla anokukhetha ioli yeglosi efanelekileyo ngokweempawu zeemveliso zabo. Ukongeza, ioyile yeglosi epholileyo kufuneka ibe nokubambelela kakuhle, umphezulu ogudileyo ngaphandle kokugoba, ukumelana nokugoba, ukumelana nokunxiba, ukumelana nokugqwala, kwaye akukho mbala ngexesha lokugcinwa.

Kukholelwa ukuba kule miba ingasentla, uninzi lwamashishini emichiza yemihla ngemihla kufuneka akwazi ukukhetha umgangatho ophezulu.ityhubhu yeplastiki yokuthambisaiimveliso zokupakisha.
