Isingeniso somkhiqizo kanye nezici
I-wax kapharafini, eyaziwa nangokuthi i-crystal wax, iwuhlobo lokuncibilika kuphethiloli, i-carbon disulfide, i-xylene, i-ether, i-benzene, i-chloroform, i-carbon tetrachloride, i-naphtha nezinye izincibilikisi ezingezona i-polar, ezingancibiliki emanzini ne-methanol nezinye izincibilikisi ze-polar.
sebenzisa
Upharafini ongahluziwe usetshenziswa kakhulu ekwenzeni umentshisi, i-fiberboard kanye neseyili ngenxa yokuqukethwe kwawo uwoyela omningi.Emuva KOKUNENGA I-POLYOLEFIN ADDITIVE KU-PARAFFIN, iphoyinti layo elincibilikayo liyakhula, ukunamathela kwayo nokuvumelana nezimo kuyanda, futhi isetshenziswa kabanzi ekukhiqizeni iphepha lokugoqa elingangenwa amanzi nelingemanzi, amakhadibhodi, ukumbozwa kwangaphandle kwezinye izindwangu namakhandlela.
Iphepha elicwiliswe ku-wax kapharafini lingalungiswa ngokusebenza okuhle okungangeni manzi kwephepha le-wax elihlukahlukene, lingasetshenziswa ekudleni, emithini nakwezinye izinto zokupakisha, ukugqwala kwensimbi kanye nemboni yokunyathelisa;Uma upharafini wengezwa entanjeni kakotini, ungenza indwangu ithambe, ibushelelezi futhi inwebeke.Upharafini ungenziwa futhi okokuhlanza, i-emulsifier, i-disperant, i-plasticizer, igrisi, njll.
Upharafini ocwengisiswe ngokugcwele kanye nopharafini ocolisiswe kancane asetshenziswa kakhulu, ikakhulukazi njengezingxenye nezinto zokupakisha zokudla, imithi edluliselwa ngomlomo kanye nezinye izinto (njengephepha lengcina, amakhrayoni, amakhandlela kanye nephepha lekhabhoni), njengezimpahla zokugqoka ezitsheni zokubhaka, ukuze kulondolozwe izithelo. [3], ukufakwa kwezakhi zikagesi, kanye nokwenza ngcono ukulwa nokuguga kanye nokuguquguquka kwerabha [4].Ingase futhi isetshenziselwe i-oxidation ukukhiqiza ama-fatty acids okwenziwa.
Njengohlobo lwempahla yokugcina amandla okushisa ecashile, upharafini unezinzuzo zokushisa okukhulu okucashile kokuguquka kwesigaba, ukuguqulwa kwevolumu encane ngesikhathi sokuguqulwa kwesigaba soketshezi oluqinile, ukuzinza okuhle kokushisa, akukho mkhuba wokupholisa, intengo ephansi nokunye.Ukwengeza, ukuthuthukiswa kwezindiza, i-aerospace, i-microelectronics kanye nobuchwepheshe be-optoelectronics ngokuvamile kudinga ukuthi inani elikhulu lokushisa elichithwayo elikhiqizwa ngesikhathi sokusebenza kwezingxenye zamandla aphezulu lingahlakazwa kuphela endaweni elinganiselwe yokukhipha ukushisa kanye nesikhathi esifushane kakhulu, kuyilapho siphansi. Izinto ezishintshayo zesigaba sokuncibilika zingafinyelela ngokushesha endaweni yokuncibilika uma ziqhathaniswa nezinto ezishintshayo zesigaba sokuncibilika, futhi zisebenzise ngokugcwele ukushisa okucashile ukuze kuzuzwe ukulawula izinga lokushisa.Isikhathi esifushane sokuphendula esishisayo sikapharafini sisetshenziswe kabanzi emikhakheni eyahlukene efana nezokundiza, i-aerospace, microelectronics nezinye izinhlelo zobuchwepheshe obuphezulu kanye nokonga ugesi ezindlini.[5]
I-GB 2760-96 ivumela ukusetshenziswa kwe-gum sugar base agent, umkhawulo ngu-50.0g/kg.Amazwe angaphandle nawo asetshenziselwa ukukhiqizwa kwephepha lerayisi elinamathelayo, umthamo ongu-6g/kg.Ngaphezu kwalokho, ibuye isetshenziswe kabanzi ezintweni zokupakisha ukudla, njengobufakazi bomswakama, ukuphikisana nokunamathela kanye nobufakazi bamafutha.Ilungele ukudla ushingamu, i-bubblegum kanye nemithi uwoyela wegolide ovumayo nezinye izakhi kanye nesithwali sokushisa, ukudiliza, ukucindezelwa kwethebhulethi, ukupholisha kanye nokunye okuxhumene ngqo nokudla nemithi (eyenziwe ngezingxenyana ze-waxy zamafutha noma uwoyela we-shale ukucindezela okubandayo nezinye izindlela).
iphakethe kanye nezokuthutha
B. Lo mkhiqizo ungasetshenziswa,,25KG,200KG,1000KGBAERRLS.
C. Gcina kuvaliwe endlini epholile, eyomile futhi engenamoya.Iziqukathi kufanele zivalwe ngokuqinile ngemva kokusetshenziswa ngakunye ngaphambi kokusetshenziswa.
D. Lo mkhiqizo kufanele uvalwe kahle ngesikhathi sokuthutha ukuvimbela umswakama, i-alkali enamandla ne-asidi, imvula nokunye ukungcola ekuxubeni.
