Ngoku izilungiselelo zakile zineengxenyeni elithathu elihluke lokuhlola izicatulo ezisetyenziswa ngokushesha kwindawo yokugcina lekhaya kunye nokusebenza kwindawo yokugcina lekhaya. Amacocotha amanye amanye angaphambili apha apho amazwi amanye amanye ayenza izinto zokungena ngeenduku zokungenisa kunye neziphucumo ezisetyenziswa ngokushesha kwindawo yokugcina lekhaya kunye nokusebenza kwindawo yokugcina lekhaya.
Yintoni ineenkomo ezikhethekileyo, eyisho ukuba zizihlaba izikarboni, kunye nokuba zihlala kwiinkululo ezilungileyo. Izinto ezilungu lokhu zihlala ngesinye isigaba esincane esixhakathelwa ngokuba njengesithelo sokuqala somisokanate. Iminyango eminingi, phakathi kweemfotheni ezinomsindo, amaphetha, amaglue kunye neemsekyansi, zikhethwe kwisebenzisi we-alkyl isocyanates. Ngokushesha, xa uvumele kuquka kusuka kwenye icomphensi elibonakaleyo okanye uvumela icala elincinci, i-alkyl isocyanates bafuneka babheke imisebenzi yakho. Yintlizyo kakhulu; ziqhumelela ngasinye ukufika kumyalezo omuhle obucabanga ukuba yintloko lemfazwe engenayo, ezininzi amaxhobo aphantsi. Ngenxa yokuhlala kokuba ziqhumelela ngamanye amaxhobo, umthondazo wakuxhobo lwe-alkyl isocyanate , ubheke ukuba uqale ukuba kuhluke kubantu abasebenzisa amaxhobo.
Izokisayana ze-Alkili zilungiselela ngokushesha kwi-chemistry yamapholimeri. Bazame ukuba amandla ababini baxheleni phakathi kompholimari, iziqalo ezinethiweyo ezinethiweyo. Umthengiso wokulanda okwangoku ngekhoyo lokulandwa, umthombo nomthengiso nokuphucuka kunye nokusetyenziswa kwamapholimari. Amapholimari angazange bayenza ngokubanzi kanye nokusebenza ngaphandle kokulanda. Izokisayana ze-Alkili zibheka futhi njengezivamile ezikhulu zokuhlala kwayo nokuhlala kakhulu kwayo kunye nokuhlala kakhulu kwayo kwaye bazame ukuba amapholimari azizange zihlale ngqo. Izinkomo zakho zizoshintsha noma zingavamele ngazo iindlela ezidingekayo ngendlela efanayo. polyol kunye no-isocyanate ziyithumeleleyo ngokukubona kwindawo ezininzi zokusebenza.
IMethanol inguquleleyo kakhulu, kunye ne-alkyl isocyanates zikujongwa ngokukhangelwa; ukukhishwa kwiichemical eziningi akwazi ukufumana imiphumela yezilungu eziqhelekileyo. Amachemical amaningi akuzange ahluleke izinyathelo zesintsha noma umzimba wabantu uma bahlale okanye bazigxile ngazo iichemical eziningi. Zizogcina ukulinganisa, amaphumo engeziweyo nokugcwaliselo okanye amaziko eziphumayo. Ukukhishwa kokuhlukeneyo nokuba kubalulekileyo kwi-alkyl isocyanates zakhiya ukulindelana nompho, kunye nokuhlola izilungu ezidingekileyo ezininzi esabelwe kakhulu. Kuneendlela ezithuthukisayo ezinakanyiswa ukuba abantu abasebenza nalo luchemical polyol isocyanate bazivele amaguni amaphantsi njengegloves, iingoggo kunye nemasheki ukuze babuyeke bonke ubucopho bawenza amalayenti awabo.
Izokisayana ezilileyo zibonisa nokuthi zineleleyo kumakhiwo okushesha. Zingabafuneka ukufinyelela ngeemithombo esonqweni, ngokuba angaphandle kwezinto ezinomsindo, njengamanzithi, amahhula kunye neemini ukuze bethole uphandla oluphephandwayo. Amakhemikali okulandelwa akusetyenziswa ukubuyisela imifanekiso emisha kunye nokuthi icala lokusebenza. ipdi isocyanate yenziwe amafadi ahlukene asebenzayo ngokuba angapheleleyo ukufinyelela ngeemithombo eliphakathi lomdlalo.
Izilungiselelo zakile ziyafunyelwe ngakubona kakhulu eminyakeni akhona ngokuba kuhluke ukuphucumana kunye neziqondiso ezifanelekayo. Zikhona lokhu ukwenzela ipolimeri yefomu lwe-polyurethane, okufuneka ngokuthetha uhlamvu kwizindlela ezindala kunye nokulinda umdlalo wesichoba. Ifomu lenye lusetyenziswa ngokushesha kwiintshukumo kunye nokusebenza kwindawo yokugcina lekhaya. Izilungiselelo zakile zisetshenziswa ukwenza amacocotha lecar kunye nezinto eziphucuma khona ezisetyenziswa ngokushesha kwindawo yokugcina lekhaya kunye nokusebenza kwindawo yokugcina lekhaya kunye nokusebenza kwindawo yokugcina lekhaya. isocyanate amaninzi amaninzi angaphambili apha apho amazwi amanye amanye ayenza izinto zokungena ngeenduku zokungenisa kunye neziphucumo ezisetyenziswa ngokushesha kwindawo yokugcina lekhaya kunye nokusebenza kwindawo yokugcina lekhaya kunye nokusebenza kwindawo yokugcina lekhaya.
