Igama Lomkhiqizo:i-phenolic resin
Ifomethi ye-molecular:
Inombolo ye-CAS:9003-35-4
Isakhiwo samangqamuzana omkhiqizo:
I-phenol-formaldehyde resin ilungiswa ngale ndlela elandelayo:
C6H5OH+H2C=O —> [-C6H2(OH)CH2-]n
Ama-Resins esiteji esisodwa. Isilinganiso se-formaldehyde ne-phenol siphezulu ngokwanele ukuvumela inqubo ye-thermosetting ukuba yenzeke ngaphandle kokwengezwa kweminye imithombo yezixhumanisi eziphambanayo.
Ama-Resins anezigaba ezimbili. Isilinganiso se-formaldehyde ne-phenol siphansi ngokwanele ukuvimbela ukusabela kwe-thermosetting ukuthi kwenzeke ngesikhathi sokwenziwa kwe-resin. Kuleli qophelo i-resin ibizwa ngokuthi i-novolac resin. Kamuva, i-hexamethylenetetramine ifakwa kokusebenza ukuze isebenze njengomthombo wamakhemikhali ahlanganayo ngesikhathi sokusebenza kokubumba (kanye nokuguqulelwa ku-thermoset noma isimo esilashiwe).
Ama-phenolic resins asetshenziselwa izingxenye ezishibhile ezidinga izakhiwo ezinhle zokuvikela ugesi, ukumelana nokushisa, noma ukumelana namakhemikhali. Isilinganiso sempilo yeshelufu yale resin cishe inyanga engu-1 ku-21.1°C. Lokhu kunganwetshwa ngokuyigcina esiqandisini ku-1.6 kuya ku-10°C. Ukushintsha i-catalyst (ngokuhambisana nobukhulu be-cast) nokukhuphula izinga lokushisa lokwelapha libe ngu-93°C kuzoshintsha isikhathi sokwelapha sisuke kumahora angu-8 siye sibe sifushane njengemizuzu engu-15.
Okunye ukuncipha kwenzeka ekubunjweni okuqediwe (0.012 kuya ku-0.6 mm/mm), kuye ngenani lokugcwalisa, inani le-catalyst, kanye nezinga lokwelapha. Imijikelezo yokwelapha esheshayo ikhiqiza izinga eliphezulu lokuncipha. Njengoba umjikelezo wokwelapha ungasheshisa, ama-phenolic asetshenziswa ekusebenzeni okufushane.
Izingxenye ze-cast phenolic zisuswa kalula esikhunjeni uma kusetshenziswa ama-ejenti ahlukanisayo anconywe umphakeli. I-Posteuring ithuthukisa izakhiwo eziyisisekelo zokusakazwa okuqediwe.
I-Chemwin ingahlinzeka ngenqwaba yama-hydrocarbon amaningi nezincibilikisi zamakhemikhali kumakhasimende ezimboni.Ngaphambi kwalokho, sicela ufunde ulwazi olulandelayo oluyisisekelo mayelana nokwenza ibhizinisi nathi:
1. Ezokuphepha
Ukuphepha kuyinto ehamba phambili yethu. Ngaphezu kokunikeza amakhasimende ulwazi mayelana nokusetshenziswa okuphephile nokunobungani kwemvelo kwemikhiqizo yethu, siphinde sizibophezele ekuqinisekiseni ukuthi ubungozi bokuphepha kwabasebenzi nosonkontileka buncishiswa bube buncane obunengqondo nobunokwenzeka. Ngakho-ke, sidinga ikhasimende ukuthi liqinisekise ukuthi izindinganiso ezifanele zokuphepha zokuthulula nokugcinwa kwempahla ziyahlangatshezwa ngaphambi kokulethwa kwethu (sicela ubhekisele kusithasiselo se-HSSE emigomeni nemibandela evamile yokuthengisa ngezansi). Ochwepheshe bethu be-HSSE banganikeza isiqondiso kulawa mazinga.
2. Indlela yokulethwa
Amakhasimende anga-oda futhi alethe imikhiqizo evela ku-chemwin, noma angathola imikhiqizo evela embonini yethu yokukhiqiza. Izindlela zokuthutha ezitholakalayo zifaka phakathi iloli, ujantshi noma ezokuthutha ezinezinhlobo eziningi (kuyasebenza izimo ezihlukene).
Endabeni yezidingo zekhasimende, singacacisa izidingo zezikebhe noma amathangi futhi sisebenzise amazinga akhethekile okuphepha/wokubuyekeza kanye nezimfuneko.
3. Inani elincane le-oda
Uma uthenga imikhiqizo kuwebhusayithi yethu, inani elincane le-oda amathani angama-30.
4.Inkokhelo
Indlela yokukhokha ejwayelekile idonswa ngokuqondile zingakapheli izinsuku ezingu-30 ukusuka ku-invoyisi.
5. Amadokhumenti okulethwa
Amadokhumenti alandelayo anikezwa ngokudiliva ngakunye:
· I-Bill of Lading, i-CMR Waybill noma enye incwadi yezokuthutha efanele
· Isitifiketi Sokuhlaziya noma Ukuvumelana (uma sidingeka)
· Imibhalo ehlobene ne-HSSE ngokuhambisana nemithethonqubo
· Imibhalo yeCustoms ngokuhambisana nemithethonqubo (uma kudingeka)
