Ipoliyuritanine isocyanate sine imigca emingezini eziphambili kwiimixhanje yomsebenzi. I-poliyuritani yi-plastiki elungelilo olunqophiso lwesikhephe, lokugqumeleka ukubonisa ukuba lufika kumthetho wokuquketha wesicatshulwa kunye namagama amahlukene angamashumi amabini amanamandla angenamandla angasemakhandelini. Amagama amahlukene amaningi lamaphakathi lalayithiwe ngokusebenzisa ipoliyuritani kunye nemibhalo enye. Ukufaka le nto kulayithiswa ukuba liwe plastiki elungelilo eliqhina kunye nokuhlobene nesikhatsi.
Okokugqibelekanga akufuneka azame ukugqiba isithombo sakho, amagcali nokulayishwa. Ukusuka kwezinto ezifana namalungu okuyizange aluleke izilungu, ukuhlaba kunye nokubhidiswa, ziqedwa ukuba umntu uzexakele isocyanate mdi ngomoya ofanele. Abafundisi abazisebenza nge-ingenzi ngaphandle komkhonto kufuneka bazamelise benzi, baze bebandakanyiswe amasiko asesiqhaza.
Yeyiphi lalaweni elahlukene lokusebenzisa kwiqheleni sabelwe ngamandla efuphiweyo emfowethweni wethu. Ukuze akuzange kuhlola ngokuphelele, iimikhalo eziphathelwe xa kuhlola iphoo yethu zizama ukuba zihlobene nomthonyama. Xa polyurethane kunye ne-isocyanate izintloko zidale, zingabhedlisele kanye nokuthi zidinge inani lemilenze. Amahlayishoni amacabango ekuvumekeneyo njenge-SANYING asebenzela ukwenzela imigomo engcono yokusebenzisa lezinto kunye nokufinyelela amandla amanqaku oludala lokusebenzisa ukuthi alulekelwe kanye nokubhekisisa ubungakanani besizwe.
Ngoku kwindawo ezininzi ezinomsindo kunye nemibuzo yenkonzo yemfowethu, ipoliyuthane yintoni ukuba umthakathi omphumeleyo ngokuthi kuhluke izinkinga ezifanayo ngezinye iimaterelya. Ingqumbo enye yezilungu zingaphambili ukuthi lokhu liphawuli phakathi komkhulu wabasebenzisi ngokuthi lokhu kunene kanye nokuphucukeleka kunye neziqhaza ezininzi zezinto ezinikezelayo. I-Polyurethane iyiphantsi kakhulu kwezintsha, ngoko ke kufanele ukusebenza nalo, kunye nokuhlukana kwiimoya nokumemezi. I-Polyurethane ingavolwa ngokubanzi ukuba kukho imibono yakhe apho inamandla kulokhu kunye nokuvolwa ngokubanzi kakhulu kunye nokusetyenziswa kakhulu kwezinye izinto. I-Polyurethane ifunyanwa ngazo zonke izimo eziqondileyo ngokuthi kuhluke kakhulu, kushona ukusebenza nalo, kunye nokugcina izinye izinto njengemoto okanye imetalu.
Abasebenzisi nobuncedo bahlola amaninzi amamethodo yokuthola amandla a-Polyurethane polyol kunye no-isocyanate ngokuya kuvamile ukulayithi. Imininingwane ezintsha ezazibuyiswa kwi-material science kunye nokhemisitri ibizela iimfanelo ezincinci kunye nezi zokuphakamisa izindlu zokuhlala. Amanxiwo ase-SANYING azifuna ukuthi le nto ikhiyiwe ngendlela efanelekileyo kodwa okanye ukuhlawulwa ngezinye izindlela ezincedwayo. Sifuna ukusombulula ukuba siyabelana ngesikhathu esiyihlala khona, isikhathu esiyihlala ngo, kunye nokuba sisebenzise amaxwebhu omncedisi.
