I-Nucleating agent iwuhlobo lwesithasiselo esisha esisebenzayo esingathuthukisa izici ezingokomzimba nezomshini zemikhiqizo efana nokubonakala ngale, isicwebezelisi esingaphezulu, amandla aqinile, ukuqina, izinga lokushisa lokuhlanekezela ukushisa, ukumelana nomthelela, ukumelana nokunwabuzelayo, njll. ngokushintsha ukuziphatha kokucwebezela kwama-resin. . Isetshenziswa kabanzi enqubweni yokukhiqiza amapulasitiki anekristalu engaphelele njenge-polyethylene ne-polypropylene ezimotweni, izinto zikagesi zasekhaya, ukudla, i-electronics, kanye nezinkundla zezokwelapha. Isibonelo, i-nucleating agent iyinto eyinhloko ekukhiqizeni ama-resin asebenza kakhulu njenge-polypropylene ephezulu ye-melt index, ukuqina okuphezulu okusha, ukuqina okuphezulu, ne-high-crystallinity polypropylene, i-β-crystalline polypropylene, nezinto eziguquliwe ze-polypropylene zezimoto. izinhlelo zokusebenza ezinezindonga ezincane. Ngokungeza ama-nucleating agents athile, ama-resin anokukhanya okuthuthukisiwe, ukuqina, nokuqina angakhiqizwa. Ngokukhula okuphawulekayo kokukhiqizwa kwasekhaya kwe-polypropylene esebenza kahle kakhulu edinga ukwengezwa kwama-nucleating agents kanye nokukhula ngokushesha kwesidingo sezihlukanisi ze-auto lightweighting kanye ne-lithium battery, maningi amathuba okuthuthuka emakethe ye-nucleating agent.
Kunezinhlobo eziningi zeama-nucleating agents, futhi ukusebenza komkhiqizo wabo kuyaqhubeka nokuba ngcono. Ngokusho kwamafomu e-crystal ahlukene abangelwa ama-nucleating agents, angahlukaniswa abe yi-α-crystalline nucleating agents kanye ne-β-crystalline nucleating agents. Futhi ama-agent e-α-crystalline nucleating angahle ahlukaniswe abe yizinhlobo ze-inorganic, organic, kanye ne-polymer ngokusekelwe ekwehlukeni kwazo kwesakhiwo. Ama-inorganic nucleating agents ikakhulukazi ahlanganisa ama-nucleating agents asanda kuthuthukiswa njenge-talc, i-calcium oxide, ne-mica, angabizi futhi atholakala kalula kodwa anokukhanya okungekuhle kanye nokucwebezela kwendawo. Ama-nucleating agents ikakhulukazi ahlanganisa usawoti wensimbi we-carboxylic acid, usawoti we-phosphate metal, i-sorbitol benzaldehyde derivatives, njll. Phakathi kwawo, okuphuma ku-sorbitol benzaldehyde kuyizinto ezikhiqiza i-nucleating ezivuthiwe, ezisebenza kahle kakhulu namanani aphansi, futhi sezithuthuke kakhulu, zihlukahlukene. , kanye nohlobo lwevolumu enkulu kakhulu yama-nucleating agents kokubili ngaphakathi nangaphandle. I-polymer nucleating agents ikakhulukazi i-high-melting-point polymeric nucleating agents, njenge-polyvinylcyclohexane ne-polyvinylpentane. Ama-β-crystalline nucleating agents ikakhulukazi ahlanganisa izinhlobo ezimbili: inani elincane lezinhlanganisela ze-polycyclic ezinezakhiwo ze-quasi-planar, kanye nalezo ezakhiwe ngama-dicarboxylic acid nama-oxides, ama-hydroxides, nosawoti wezinsimbi ezivela kuQembu IIA lethebula le-periodic. I-β-crystalline nucleating agents iqinisekisa izinga lokushisa le-thermal deformation lemikhiqizo ngenkathi ithuthukisa ukumelana nomthelela wayo.
Izibonelo Zemisebenzi Yomkhiqizo kanye Nezicelo Zama-Nucleating Agents
| Imikhiqizo | Incazelo Yomsebenzi | Izinhlelo zokusebenza |
| I-Transparent Nucleating Agent | Ingathuthukisa kakhulu ukubonakala i-resin, inciphisa inkungu ngaphezu kwama-60%, ngenkathi kwandisa izinga lokushisa lokushisa kanye nezinga lokushisa le-crystallization i-resin ngo-5 ~ 10 ℃, kanye nokwenza ngcono i-flexural modulus ngo-10%~15%. Iphinde ifinyeze umjikelezo wokubumba, ithuthukisa ukusebenza kahle kokukhiqiza, futhi igcina ukuqina komkhiqizo. | I-High Melt Index Polypropylene (noma High MI Polypropylene) |
| I-ejenti Eqinisa I-Nucleating | Ingathuthukisa kakhulu izakhiwo zemishini ye-resin, ngokukhuphuka kwe-flexural modulus namandla okugoba angaphezu kwama-20%, kanye nokwenyuka kwezinga lokushisa lokuhlanekezela ukushisa ngo-15 ~ 25℃. Kukhona futhi ukuthuthukiswa okuphelele nokulinganisela ezicini ezihlukahlukene ezifana nezinga lokushisa le-crystallization namandla omthelela, okuholela ekuncipheni okulinganiselayo kanye nokuncipha kokuwohloka kwekhasi le-warpage lomkhiqizo. | I-High Melt Index Polypropylene, I-High-Rigidity Entsha, I-High-Toughness, ne-High-Crystallization Polypropylene, I-Modified Polypropylene Material ye-Automotive Thin-Wall Application |
| I-β-Crystalline Toughening Nucleating Agent | Ingakwazi ukukhiqiza ngempumelelo ukwakheka kwe-β-crystalline polypropylene, ngenani lokuguqulwa kwe-β-crystalline elingaphezu kwama-80%, kuthuthukisa kakhulu amandla omthelela we-polypropylene resin, futhi isithuthukisi singafinyelela izikhathi ezingaphezu kwezingu-3. | I-High Melt Index Polypropylene, I-High-Rigidity Entsha, I-High-Toughness, ne-High-Crystallization Polypropylene, i-β-Crystalline Polypropylene |
