I-Polyurethane yimathiriyeli yodwa esetyenziswa ngabantu kumakhulu eempahla zabathengi. Kukoomatrasi abahonjisiweyo, ifenitshala ethambileyo, kunye nakwizixhobo zemoto ezenza ukuba zihambe ngokulula. I-Perk inombolo yokuqala, i-polyurethane yomelele kakhulu kwaye inokubunjwa kuyo nantoni na. Nangona kunjalo, ngaba uyazi ukuba kukho ikhemikhali enye esebenza njengeyona nto iphambili ekwenzeni i-polyurethane - isocyanate.
Yintoni i-Isocyanate?
I-Isocyanate yimathiriyeli ekrwada esetyenziswa kwimveliso ye-polyurethane. Yikhemikhali edibana nezinye iikhemikhali. Iipholima zenziwa ngokusabela ngokwekhemikhali ecaleni kwetsheyini lezo khemikhali. Ipolymer ngokwayo yinto enika i-polyurethane iimpawu ezizodwa zamandla, ubude, kunye nokuqina.
Kutheni i-Isocyanate ibalulekile
Ukusetyenziswa kwe-isocyanate kwenza kube yinto esisiseko ekrwada xa kusenziwa iimveliso ze-polyurethane. I-Isocyanate yenza inxalenye yethambo lomqolo elinika izinto eziphathekayo amandla kunye nokuguquguquka. Ngamanye amazwi, ngaphandle kwe-isocyanate, i-polyurethane yayingayi kuba luncedo okanye ithembekile kwindawo yokuqala. Kwaye ke, ukuqonda indima ye-isocyanate kubaluleke kakhulu kuye nabani na owenza okanye osebenza nge-polyurethane.
I-Isocyanate iNcedisa kwiiMveliso ezahlukeneyo
Enye into enhle malunga ne-isocyanate kukuba inokuxutywa kunye nezinye iikhemikhali ngeendlela ezahlukeneyo zokwenza zonke iintlobo zeemveliso ze-polyurethane. Ngokulungelelanisa ubungakanani be-isocyanate esetyenzisiweyo, umzekelo, unokwenza amagwebu athambileyo oomatrasi okanye iiplastiki eziqinileyo kwiindawo zemoto. Oku kuguquguquka kwenza kube lula ukuba abavelisi beze noluhlu olubanzi lweemveliso ezinokuhlangabezana neemfuno ezithile. I-Isocyanate iphinda ingene kwiingubo ezigubungela umphezulu wokukhusela kunye ne-adhesives ebamba izinto kunye.
Ixabiso elifanelekileyo le-Isocyanate
Ukwenziwa kwePolyurethane kuxhomekeke kakhulu kwi-isocyanates kwaye kulula ukuba buthathaka. I-isocyanate eninzi kakhulu iya kwenza izinto eziphathekayo, ziqhekeke ngokulula. Ngakolunye uhlangothi, ukungonelanga kwe-isocyanate kuya kunika i-polyurethane enesiphumo kakhulu kwaye ibuthathaka. Kodwa nge-isocyanate efanelekileyo, i-polyurethane inokungqina ukuba yomelele kwaye iguquguquke kanye. Ulungelelwaniso olunjalo yinto eyenza ukuba izinto eziphathekayo zibe luncedo kwi-parade engenakubalwa yeemveliso ezahlukeneyo.
Ukubaluleka kwe-Isocyanate kwiMveliso yePolyurethane
Ihambile isocyanate Le yinxalenye ebalulekileyo yentelekelelo yokwenza ipolyurethane. Le nkqubo inceda ukwenza imathiriyeli eyomeleleyo neyinjongo ezininzi esetyenziswa kwiimveliso ezininzi ezahlukeneyo. I-Isocyanate yintoni eyenza i-polyurethane isebenze kwaye iluncedo kubomi bethu bemihla ngemihla; ngaphandle kwayo, besiya kuba nokuncinci kakhulu! Esinye isizathu sokuba abavelisi bazi indlela yokusebenzisa isocyanate ukwenza i-polyurethane ngokuchanekileyo.
E-SANYING, siyazi kakuhle ukuba i-isocyanate sisitshixo sokuvelisa i-polyurethane ephezulu. Sisebenzisa elo xesha kunye nezixhobo ukwenza ezona isocyanates zibalaseleyo kubathengi bethu. Izixhobo zethu zingena kuyo yonke into ukusuka koomatrasi be-cushy be-foam ezikunceda ukuba ulale kwiindawo zemoto ezomeleleyo ezenza iimoto ziphile. Sizibophelele ekuhambiseni abathengi bethu izixhobo ezisemgangathweni ukwenza iimveliso ezomeleleyo nezisebenzayo zepolyurethane.
Ngamafutshane, i-isocyanate lelona galelo libalulekileyo ekwenzeni i-polyurethane. Eyangaphambili isetyenziselwa ukwenza izinto ezininzi eziqinileyo nezithambileyo ezinokuthi zisetyenziswe ngokulula kwiimveliso ezahlukeneyo. Ngoku uyazi malunga ne-isocyanates, uyayazi indlela abavelisi abasebenzisa ngayo ngoku olu lwazi ukuyila kunye nokwenza iimveliso eziphantsi kakhulu ze-mda pdc polyurethane kumntu wonke kuyo yonke indawo. Umgca wethu we-isocyanates wenza ukuba uphuhlise iimveliso eziphucula ubomi babantu mihla le.
