Ipoliyuthane yichophu elingaziwayo okanye umthombo omkhulu oluzama abantu kuzama ngemibhalo yezintathu ezimbili. Ikhona kumathhethi ephakamisayo, amafurniture amanqanawa nokuphela, futhi phakathi kwamakhomponi akwesikweletu esizoba ukugxaba ngokushaya. Ukubuyelekiswa lokuqala, ipoliyuthane ingunye into engazange aluhlale inqanawe kunye nokuba kube ngenxa yokuba ibuyelekisele kuwo wonke amagama. Ngoko ke, ungayazi ukuba kukho into enye eyodwa elikhoyo lokusebenzeka njengokubonisa ipoliyuthane - isiyosifanele.

Ngubani Isocyanate?

Isiyosifanele yichophu elusetyenziswa lokulawula ipoliyuthane. Yichophu elihamba ngaphandle kokufika nokusetshenziswa ngechophu ehlukene. Amapolimeri azisetshenziswa ngokusetshenziswa cheme ngaphakathi kwechophu echelwe ekhatheni lwayo. Ipolumeri yasebenza ukuba ipoliyuthane iyiphakamise yiyo ngeamandla, iinkcukacha nokuba buyelekisele.

Yini Okungadinga Isiyosifanele?

Ukusebenzisa kwe-isocyanate iyenza ukuba yile yiyo umthombo omphumayo wendawo elandelwayo xeswi lapho kulungiselela amanqaku apho apheleleyo ngokulandelwa kwe-polyurethane. Isocyanate ifuneka emanzini wenqanawa yokuthi ingxenye yomthombo ongenzi ukuthi umlomo waye ukuhlaba nokuqinisekiswa. Ngoko ke, angaze kuqala isocyanate, ipolyurethane ayithathelani okanye ayiqinisekanga ngokuphela kusukela. Ngakwesobizo, ukubuya kwisicelo sesisicelo sokuthetha ngokugcina kwe-isocyanate siyinqatha engeke kuhluke kakhulu xa kunye nesi polyurethane.

Isocyanate Usiza Izinto Ezininzi

Yinto engamaziyo ngokuthi leyo isocyanate inakwa imibuzo eziningi ngokuyingxenye yokuhlaba nokuthetha ngazo izinto ezininzi zepolyurethane. Ukufaka ukuthi ububelele kwe-isocyanate, phambi kokufika kwezinto ezinje eziphumuleleyo, uzange uhlale ukwenza amasipho amahhulu amandla apha ezintsha zezilondolozi. Le ndlela yokungaphumeleleyo icala ukuba amaphrodyuseri akwazi ukwenza umsindo ombili wamanqaku apho azifuna imithetho esidingiweyo. Isocyanate iyayinye yezinto ezinikezela amacoco amaphandle amaphindaphinde amalayisi amaqinisekise amabuye amahlale amagciniselo.

Izibophezulu zokugcina kweIsocyanate

Ukubuyisela kwepolyurethane kuhlonelwa ngeminye eyahlukene nezi-isocyanate kunye nokuba kusayiqhele. Ukufakwa kakhulu kwesi-isocyanate uzoba lizama ukulandwa lokulamba, ukuze alenzeke. Ngokwesobunye, ukufakwa ngenqanawe kwezi-isocyanate uzoba uzifaka ipolyurethane elincinci kunye nenqanawe. Kodwa, ngenxa yokufakwa kakhulu kwezi-isocyanate, ipolyurethane uzoba luhlabe kunye nokuphucwayo ngaphandle kokuthi. Leli balance kulungileyo yinto engazange asetye ngaso emileni elinamandla.

Ukuphakamisa kwezi-Isocyanate kwiQhagamshini lePolyurethane

Zaqhubekelayo i-Isocyanate. Yintoni ifanele lokuhlola ukubuyisela kwepolyurethane. Uphawuli lokulandelana lelendlela lilungiselela umthombo omncedisi kunye nokuziphatha kakhulu okanye ongcaciso. I-Isocyanate yinto yokungcono kunye nokungabonakalayo ipolyurethane kwenye into zethu ezintathu; ngaphandle kokuthi, angazange sibheka kahle! Yindlela yokuqala yezilungiseleyo zokushicilela ukufaka kwezi-isocyanate ukubuyisela kwepolyurethane ngokubona.

Ku-SANYING, siyazi ngokuphathelene ukuthi isocyanate yilizinto elikhulu lokusebenzela ukubuyisela polyurethane. Siyisebenzisa amaxesha kunye nezi zindlela zakwakhiwo lokuhlola isocyanates ezibomvu zethu. Izixhobo zethu zikwazi ukusuka kwezintsha zemfino ezinceda ukulala kwesibhedlela somntu ukusukela kwezixhobo zombhalo ezinceda ukufakwa kwezincinci. Sihlobongo ukuthi sibuyelela izixhobo zethu eziphakeme ukuba zibe ngeendlela ezidingekayo ukwenza imiphumela ye-polyurethane ekugcwaleni kunye nokungaphambili.

Ngoku qaphela, isocyanate yilizinto elikhulu lokusebenzela lamanje yepolyurethane. Lolu nyangasebenza kulandelwa kunezinye iindawo ezifanele ukusetshenziswa kwindawo ezininzi eziningi. Manje uma usayiqinisekisiwe ngokuthi ngokwesobizo, uzazi ukuthi umphakathi wamandla anomaqondana nothile usebenzisa le nto lokuhlola ukwenza imiphumela yesiphephandaba lowubonakaliyo lowayidibaniswayo lowayithunyelwa yezindinga ze-polyurethane kuzo kuzo. Isiko lesakuzelekelwa lakho lisetyenziswa ukwenza amaxwebhu omuhle okudingeka ukuthola ukuhlola kweendlela zokuhlola kweendlela zokuhlola kweendlela zokuhlola.
