Ngaphandle kokubona, ngaba ungene ukucabanga ngaphandle lokusho ngaphi imibuzo engenayo? Ngoku yintlango elithile lezinto zokugcina kwezinye izinto ezininzi? Yintloko yokuba lento yilo polyurethane, noma PU ngokwesikhatsi. PU yilophandle lolunye uhlamvu olungaphakathi kwezinto ezinomsindo ezininzi njengemathetha, amabhukuku, kunye nokuphakamisa komphendulo. Kune ntlanga enjalo eyaziwa ngokubanzi njengemibhalo aqhelekileyo, blocked isocyanate, esebenza ukuthola ukuba PU asiphumelele phambi kokuba wusayisela kuhlaleni lakho polysilicate. Ukuba apho ayiqhubekise ukulandelela kwakhona ku-PU.
Yintoni Blocked Isocyanate?
Blocked isocyanate: Umncedo omkhulu owenza ukuthi PU asiphumelele ukufika kumalelezo omkhulu ngezinto ezilandelayo. Lomncedo omncedisiwe khona alandelela ngesicatshulwa noma izinto ezilandelayo ezintsha kwi-PU. Ukuba apho ayiqhubekise ukuba PU akhululekile futhi akusayisela ngaphakathi komhlawulo.
Amasiko Aku-Blocked Isocyanate
Bheka ukuthi iiphrodyakhti zesiPU zinokulawula kakhulu ngomoya wokuqala wesikhansi. Lolu hlobo lokuhlola kulungile ukuba amanxoxo angasemva kahle, apho amandla nokubhedlise kuhluke kwezinye izikhatsi. Umoya wokuqala wesikhanzi wenze ukuthi amandla kwezi PU zingasemva kahle ngenxa yokuba zizifunyenwe ngendlela ezidingekayo.
Ngaphi kunjalo umoya wokuqala wesikhanzi wenze imisebenzi yakhe?
Lokhu kulungileyo kwiindawo ezininzi, okuyinto engcono kakhulu. Ngexesha lokho leshikhanzi lalaywa, alingatholakali ngeamandla ethile. Lokhu kuhlanganisa ukuba ukuhlola kwe-PU akufanele ukuphumelela ngqukuze lube ngaphandle kokuthi iphrodyakhti yase PU yilungileyo ngokushesha. Ngokwesobizo, amandla ase PU abe ekusenzelweni komoya wokuqala wesikhanzi enze ukuthi ungenziwe ngokukhanya kakhulu.
Iindlela zokusebenzisa umoya wokuqala wesikhanzi
PU isocyanate mdi abanye ababonisa ukuthi bengene ukuthola umoya wokuqala wesikhanzi wokusetyenziswa. Ngalokho, lokho lixhasa:
Khetha umoya wokuqala wesikhanzi olungileyo kwisekhaya lakho.
Sebenzisa isophanate esebekwe kwiiphrodyakthi zakho ngenqaku lomixhesho olulandelayo kunye nomncedo.
Izinto eziphathisayo kwenziwa kusasiphi, esikhohle ngokuthi akukho ukumelana nokushintsha okungaba ubukhulu obavumele umkhonto wabo.
Sebenzisa amancamulo apha ukuvimbisisa ukuba uthole isophanate esebekwe kwiiphrodyakthi zakho ezithile nezingca zonke.
Amasiko Aku-Blocked Isocyanate
Ngusebenzisa isophanate esebekwe, ungene ngokuphelelela ukubonisa idamage kwiiphrodyakthi ezivunyelwe. Ngubhlokishi weisophanate ngaphandle kokuthi kuzoshintshwa ngquku kakhulu, bahlala amaninzi okanye abe ngendawo yokugcina uqukethwe kwesikhashana. Kungenza lokho ukuba iziphrodyakthi zisekelwe ngempela, kodwa kukwenza ukuba zifundise ngokukhoyo nalokhu bazibuyekezwa.
Ngakwesobizo, mdi isocyanate yingxu ye ndawo yokugcina elingqalelwa kunye nokuhlawula umthakathi wokusebenza kakhulu kwezinto ezilungileyo zesiPU. Ischofield: Umkhombiso Omfanelelowo Lwesiqephu Sesibini LesiBlocked Isocyanate – Ngokuba uzixhasa ukuthi ngaphandle kokufuneka lokulandelana nendlela, amaphethelo kunye neziindlela zokusebenza, abasebenzisi bazokuthola izindaba ezidingekileyo ukuze bazingeniswe blocked isocyanate kwiindlela zakho. Izinto zePU zimeleke ithafa elikhulu lokusebenza kunye nokubizwa ngokukhona ngokusemthethweni esisodwa singeziseleyo kunye nokuphucumeka kakhulu.
