Njengesixhobo esibalulekileyo sekhemikhali,isitayileisetyenziswa kakhulu kwiiplastiki, irabha, iipeyinti kunye neengubo. Kwinkqubo yokuthengwa kwempahla, ukhetho lomthengisi kunye nokusingatha iimfuno zokhuseleko luchaphazela ngokuthe ngqo ukhuseleko lwemveliso kunye nomgangatho wemveliso. Eli nqaku lihlalutya ukuphathwa kwe-styrene kunye neemfuno zokhuseleko ukusuka kwimilinganiselo emininzi yokukhetha umthengisi, ukubonelela ngereferensi kubasebenzi bezoshishino beekhemikhali.
Iikhrayitheriya eziPhambili zokuKhetha uMboneleli
Isiqinisekiso soMboneleli
Xa ukhethaababoneleli be-styrene, ingqwalasela ephambili kufuneka inikwe abavelisi abakhulu abaqinisekisiweyo ngabasemagunyeni belizwe abaneelayisensi zoshishino ezifanelekileyo kunye neemvume zokuvelisa. Ukuphonononga iilayisenisi zoshishino kunye neemvume zemveliso kunokuvavanya kwangaphambili iziqinisekiso zenkampani kunye nokuthembeka kwayo.
Umjikelo wokuhanjiswa
Umjikelo wokuhanjiswa komthengisi ubalulekile kucwangciso lwemveliso. Uthathela ingqalelo umjikelo wemveliso omde we-styrene, ababoneleli kufuneka babonelele ngenkxaso yonikezelo ngexesha ukunqanda ukuphazamiseka kwemveliso.
Umgangatho weNkonzo
Ukukhethwa komnikezeli kufuneka kuthathelwe ingqalelo iinkqubo zenkonzo emva kokuthengiswa, kubandakanywa ukuhlolwa komgangatho wasemva kokuhanjiswa kunye nobuchule bokusombulula iingxaki. Ababoneleli bekhwalithi baphendula ngokukhawuleza kwimiba yokuqinisekisa imveliso engaphazamisekiyo.
Iindlela zoThutho kunye neeMfuno zoHambo
UKhetho lweNdlela yoThutho
Njengolwelo okanye into eqinileyo, i-styrene iqhele ukuthuthwa ngolwandle, umhlaba okanye umoya. Uthutho lolwandle lunikezela ngeendleko eziphantsi kwimigama emide; izithuthi ezihamba emhlabeni zibonelela ngeendleko eziphantsi kumgama ophakathi/omfutshane; imithwalo yomoya iqinisekisa isantya kwiimfuno ezingxamisekileyo.
Iindlela Zokuphatha
Kufuneka kuqeshwe amaqela okuphatha aqeqeshelwe ukunqanda ukusebenzisa abasebenzi abangaqeqeshwanga. Ukusebenza ngokucokisekileyo ngexesha lokuphatha kuthintela umonakalo wemveliso, ingqwalasela ekhethekileyo ekukhuseleni izinto ezilungele ukutyibilika.
IiMfuno zokuPakisha kunye nokuPhathwa koKhuseleko
Ukupakishwa kwezinto eziKhethekileyo
I-PEB (i-polyethylene ethyl) izinto zokupakisha, ezingenayo ityhefu, i-heat-resistant-resistant kunye nobungqina bomswakama, zifanelekile kwi-styrene. Xa ukhetha ababoneleli bokupakisha be-PEB, qinisekisa iziqinisekiso zabo zemathiriyeli kunye neziqinisekiso zemveliso.
Iinkqubo zokuphatha
Landela ngokungqongqo imiyalelo yokupakisha kunye neenkqubo zokusebenza ngexesha lokuphatha. Phatha ngononophelo ukuphepha umonakalo wokupakisha. Kwizinto ezinkulu, sebenzisa izixhobo zokuphatha kunye nezixhobo zobuchule ukuqinisekisa ukhuseleko.
UVavanyo loMngcipheko kunye naManyathelo aNgxamisekileyo
Ukujongisisa ubungozi
Vavanya imingcipheko enokubakho yabaxhasi kuquka ukulibaziseka kokunikezelwa, imiba yomgangatho kunye neempembelelo zokusingqongileyo ngexesha lokuthengwa kwempahla. Hlalutya iingxaki zembali yababoneleli kunye neerekhodi zengozi ukuze ukhethe iindlela ezinomngcipheko ophantsi.
ULungiselelo oluNgxamisekileyo
Phuhlisa izicwangciso zongxamiseko kwaye uqhube uqhelo lweengozi ezinokubakho ngexesha lokuphatha kunye nokugcinwa. Kwizinto ezinokutsha/eziqhumayo ezifana ne-styrene, gcina amaqela aqeqeshiweyo eempendulo zikaxakeka kulawulo lwezehlo ezikhawulezayo.
Ukuqukumbela
Ukukhetha ababoneleli be-styrene abafanelekileyo akuchaphazeli iindleko zemveliso kuphela kodwa ngokubaluleke kakhulu, ukhuseleko lwemveliso kunye nomgangatho wemveliso. Ukukhethwa kwababoneleli kufuneka kugxininise kwiimpawu ezinzima ezifana nezatifikethi, imijikelo yokuhanjiswa kunye nomgangatho wenkonzo, ngelixa likwajongene neemfuneko zokhuseleko lokuphatha kunye nokugcinwa. Ukuseka iinkqubo ezibanzi zokukhetha ababoneleli kunye neendlela zokhuseleko kunokunciphisa ngempumelelo imingcipheko yemveliso kunye nokuqinisekisa ukusebenza kweshishini eliqhelekileyo.
