Ukwethulwa komkhiqizo nezici
Upharafini wax, owaziwa nangokuthi i-Crystal Wax, uhlobo lokuncibilika ephepheni, i-chobon dislefide, i-ether, i-betzene, uNaphtha kanye nezinye izimbumbulu ezingezona ze-metharol, ama-methar sols kanye nezinye izixazululo ze-polar.
umsebenzi
I-Crude Paraffin isetshenziswa ikakhulukazi ekwenziweni kwemidlalo, i-fiberboard kanye ne-canvas ngenxa yokuqukethwe kwawo kawoyela okuphezulu. Ngemuva kokungeza isengezo se-polyoolefashini kuphalafini, iphuzu laso elincibilikayo liyanda, ukunamathela kwalo kanye nokuqina kokuguquguquka kwezinguquko, futhi kusetshenziswa kabanzi ephepheni lokugoqa umswakama kanye namakhandlela, ukunamathela komhlaba okuthile kwezindwangu ezithile namakhandlela.
Iphepha elicwiliswe kupharafini i-wax lingalungiswa ngokusebenza okuhle kwamanzi amaphepha ahlukahlukene we-wax, kungasetshenziswa ekudleni, emithini kanye nokunye ukufakwa, ukuwohloka kwensimbi kanye nomkhakha wokuphrinta; Lapho uphalafini lengezwa e-ntambo yekotoni, kungenza izindwangu zithambile, zibushelelezi futhi zinwebe. Upharafini futhi angenziwa okokuhlanza, i-emulsifier, ehlakazekile, i-spitizer, i-grease, njll.
Uphalafini ocwengekile ngokuphelele kanye ne-semi-refindied asetshenziswa kabanzi, ikakhulukazi njengezakhi kanye nezinto zokupakisha zokudla, umuthi womlomo kanye nezimpahla ezithile (njengephepha le-wax, njengezinto zokugqoka zekhabhoni), ukulondolozwa kwezithelo [3], kokufakwa kwezinto zikagesi, kanye nokwenza ngcono anti-ukuguga nokuguquguquka kwenjoloba [4]. Ingasetshenziswa futhi nge-oxidation ukukhiqiza ama-acid anamafutha.
Njengohlobo lwe-Latent Heat Energy Startation Sergy Startal, i-Paraffin inezinzuzo zokushisa okukhulu kwe-latent zokushintshwa kwesigaba, ukushintshwa kwevolumu encane ngesikhathi sokuguqulwa kwesigaba esiqinile, ukuqina okuhle okushisayo, akukho nto engaphansi, intengo ephansi nokunye. Ngaphezu kwalokho, ukuthuthukiswa kwendiza, i-aerospace, ama-microelectonics kanye ne-opoleelectronics technology kuvame ukudinga ukuthi inani elikhulu lokushisa elikhishwe ngesikhathi sokusebenza kwezakhi ezisezingeni eliphakeme lingahlakazwa endaweni enomkhawulo wokushisa, ngenkathi kuphansi I-Melting Point Isigaba Sokushintsha izinto zingafinyelela ngokushesha iphuzu lokuncibilika uma liqhathaniswa nezinto zokwakha isigaba esiphakeme sokushintsha, futhi zisebenzise ngokugcwele ukushisa okugcwele ukuze ufinyelele ukulawulwa kokushisa. Isikhathi esifushane sokuphendula esishisayo sikapharafini selisetshenziswe kabanzi emikhakheni ehlukahlukene njengendiza, i-aerospace, ama-microelectronics kanye nezinye izinhlelo zobuchwepheshe obuphakeme kanye nokulondolozwa kwamandla ezindlu.

I-GB 2760-96 ivumela ukusetshenziswa kwe-Gum Sugar Base Agent, umkhawulo uneminyaka engama-50.0g / kg. Kwangaphandle kusetshenziselwa ukukhiqizwa kwamaphepha anamathelayo erayisi, umthamo we-6g / kg. Ngaphezu kwalokho, kusetshenziswa kabanzi ezintweni zokupakisha zokudla, ezinjengobufakazi, obunamathela futhi bufakazi. Ilungele ukufundwa kokuhlafuna kokudla, i-bubblegum ne-Medicine Amafutha egolide anempilo nezinye izingxenye kanye nokushisa, ukucindezela kwethebhulethi, ukuphazanyiswa kanye nezinye izingxenye ze-wax ngqo kawoyela noma ngowoyela we-shale ngu Ukucindezela kubanda nezinye izindlela).
iphakheji nokuhamba
B. Lo mkhiqizo ungasetshenziswa ,, 25kg, 200kg, 1000kgbaerls.
C. Isitolo esivalwe ngendawo epholile, eyomile futhi enomoya ongena ngaphakathi. Iziqukathi kufanele zivalwe ngokuqinile ngemuva kokusetshenziswa ngakunye ngaphambi kokusebenzisa.
D. Lo mkhiqizo kufanele uvalwe kahle ngesikhathi sokuhamba ukuvikela umswakama, i-alkali ne-acid, imvula nokunye ukungcola okukuxubana.
