Igama lemveliso:phenolic resin
Ifomathi yemolekyuli:
Inombolo yeCAS:9003-35-4
Ulwakhiwo lwemolekyuli yemveliso:
I-Phenol-formaldehyde resin ilungiswa ngolu hlobo lulandelayo:
C6H5OH+H2C=O —> [-C6H2(OH)CH2-]n
IiResins zenqanaba elinye. Umlinganiselo we-formaldehyde kwi-phenol uphezulu ngokwaneleyo ukuvumela ukuba inkqubo ye-thermosetting yenzeke ngaphandle kokongezwa kweminye imithombo ye-cross-link.
IiResins ezinamanqanaba amabini. Umlinganiselo we-formaldehyde kwi-phenol uphantsi ngokwaneleyo ukukhusela ukusabela kwe-thermosetting ukuba kwenzeke ngexesha lokwenziwa kwe-resin. Ngeli xesha i-resin ibizwa ngokuba yi-novolac resin. Emva koko, i-hexamethylenetetramine ifakwe kwizinto eziphathekayo ukuze isebenze njengomthombo weekhemikhali ze-cross-links ngexesha lomsebenzi wokubumba (kunye nokuguqulwa kwi-thermoset okanye imeko ephilisiwe).
I-Phenolic resins isetyenziselwa iindawo ezinexabiso eliphantsi ezifuna iipropathi ezilungileyo zokugquma umbane, ukuxhathisa ubushushu, okanye ukuxhathisa imichiza. I-avareji yobomi beshelufu yale resin imalunga nenyanga e-1 kwi-21.1°C. Oku kunokwandiswa ngokuyigcina kwisikhenkcisi kwi-1.6 ukuya kwi-10°C. Ukutshintsha i-catalyst (ngokobukhulu be-cast) kunye nokunyusa ubushushu bokunyanga ukuya kwi-93 ° C kuya kutshintsha ixesha lokunyanga ukusuka kwi-8 h ukuya kwi-15 min.
Okunye ukucutheka kwenzeka ekubunjweni okugqityiweyo (0.012 ukuya ku-0.6 mm/mm), kuxhomekeke kubungakanani bokugcwalisa, isixa se-catalyst, kunye nenqanaba lokunyanga. Imijikelo yonyango ekhawulezayo ivelisa izinga eliphezulu lokucutheka. Kuba umjikelo wonyango unokukhawuleziswa, i-phenolics isetyenziswa kwimisebenzi emfutshane.
Amalungu e-phenolic asuswa ngokulula kubumba ukuba ii-arhente zokwahlukana ezicetyiswa ngumthengisi ziyasetyenziswa. I-Posteuring iphucula iipropathi ze-thebasic zokuphosa okugqityiweyo.
I-Chemwin inokubonelela ngoluhlu olubanzi lwee-hydrocarbons ezininzi kunye nezinyibilikisi zeekhemikhali kubathengi bamashishini.Ngaphambi koko, nceda ufunde olu lwazi lulandelayo olusisiseko malunga nokwenza ishishini nathi:
1. Ukhuseleko
Ukhuseleko yeyona nto iphambili kuthi. Ukongeza ekunikeni abathengi ngolwazi malunga nokusetyenziswa ngokukhuselekileyo nokuhambelana nokusingqongileyo kweemveliso zethu, sikwazimisele ekuqinisekiseni ukuba imingcipheko yokhuseleko lwabasebenzi kunye neekontraka ziyathotywa ukuya kutsho kubuncinane obufanelekileyo nobunokwenzeka. Ngoko ke, sifuna ukuba umthengi aqinisekise ukuba imigangatho efanelekileyo yokukhutshwa kunye nokugcinwa kwemigangatho yokhuseleko idibene ngaphambi kokunikezelwa kwethu (nceda ubhekisele kwisihlomelo se-HSSE kwimimiselo jikelele kunye neemeko zokuthengisa ngezantsi). Iingcali zethu zeHSSE zinokubonelela ngesikhokelo kule migangatho.
2. Indlela yokuhambisa
Abathengi banokuodola kwaye bahambise iimveliso kwi-chemwin, okanye banokufumana iimveliso kwisityalo sethu sokuvelisa. Iindlela ezikhoyo zothutho ziquka iilori, uloliwe okanye uthutho lweendlela ezininzi (kuyasebenza iimeko ezahlukileyo).
Kwimeko yeemfuno zabathengi, sinokucacisa iimfuno zeenqanawa okanye iitanki kwaye sisebenzise imigangatho ekhethekileyo yokhuseleko / ukuhlaziya kunye neemfuno.
3. Ubuncinci bobungakanani bomyalelo
Ukuba uthenga iimveliso kwiwebhusayithi yethu, ubungakanani obuncinci bomyalelo ziitoni ezingama-30.
4.Intlawulo
Indlela yokuhlawula eqhelekileyo itsalwa ngokuthe ngqo kwiintsuku ezingama-30 kwi-invoyisi.
5. Amaxwebhu okuhanjiswa
La maxwebhu alandelayo anikwe ngokuziswa ngakunye:
· Ibhili yokuLading, i-CMR Waybill okanye olunye uxwebhu olufanelekileyo lwezothutho
· Isatifikethi sokuHlalutya okanye ukuThobela (ukuba siyafuneka)
· Amaxwebhu anxulumene neHSSE ngokuhambelana nemigaqo
· Amaxwebhu ezinto eziqhelekileyo ngokuhambelana nemigaqo (ukuba kuyafuneka)
