I-Nucleating Agent uhlobo lwesengezo esisha esisebenzayo esingathuthukisa izakhiwo zomzimba nezemishini ezinjengokusobala, ukumelana nokushisa, ukumelana nokushisa, ukumelana nokushisa, njll ngokushintsha indlela yokuziphatha kwe-crystallization yama-resins. Kusetshenziswa kabanzi kwinqubo yokukhiqiza ye-crystalline plastist enjenge-polyethylene ne-polypropylene kwizimoto, i-applical yasekhaya, ukudla, ama-elekthronikhi, kanye nezinkundla zezokwelapha. Isibonelo, i-ejenti ye-nuclileating iyinto ebalulekile ekukhiqizweni kwama-resin asebenza kahle afana ne-polypropylene ephezulu, ubulukhuni obuphakeme, ne-crystalline polypropylene, kanye nezinto eziguquliwe ze-polypropylene zezicelo zezimoto ezihlangene. Ngokungeza ama-ejenti athile e-nucphezuluating, ama-resins anokubanjiswa okuthuthukile, ukuqina, kanye nobunzima kungakhiqizwa. Ngokwanda okukhulu ekukhiqizweni kwasekhaya kwe-polypropylene ephezulu edinga ukungezwa kwama-ejenti we-nuclileating kanye nokukhula okusheshayo kwesidingo sabahlukanisi bezimoto ezilula kanye ne-lithium, kunethuba lokuthuthuka kwemakethe ye-nuclileating in.
Kunezinhlobo eziningi zeama-nuclileating agents, futhi ukusebenza kwabo komkhiqizo kuyaqhubeka ukuthuthuka. Ngokwefomu le-crystal elihlukile elidonswa ama-nclileating agents, lingahlukaniswa abe ama-ejenti we-α-Crystalline nuclalling kanye nama-β-crystalline nuclileating agents. Futhi ama-ejenti we-α-Crystalline Nuclileating angahle ahlukaniswe ezinhlotsheni ze-inorganic, ezi-organic, kanye ne-polymer ezisuselwa kumahluko wazo wesakhiwo. Ama-ejenti we-inorganic nuclileating ikakhulukazi afaka ama-ejenti athuthukiswe ama-nucc, i-calcium oxide, kanye ne-mic, engabizi futhi okulula ukuyithola kepha kube nokusobala okusobala kanye nokusobala komhlaba. Ama-ejenti we-organic nucleating afaka usawoti wensimbi ye-carboxylic, i-phorbibitte yensimbi, ama-sorbitlol benzeldehyde okuvela kubo, asebenze kahle kakhulu namanani aphansi, futhi abe nohlobo lwe-nucleating agents bobabili abasekhaya nakwamanye amazwe. Ama-ejenti we-polymer nuclileating ikakhulukazi anama-polymeric nucting-point acents agents, anjenge-polyvinylcyclohexane ne-polyvinyllpentan. Ama-ejenti we-β-crystalline nuclating ikakhulukazi aqukethe izinhlobo ezimbili: inani elincane lezinhlanganisela ze-polycyclic ezinezinhlaka ze-quicarboxylic kanye no-oxides, ama-hydroxides, nosawoti wezinsimbi ezivela eqenjini le-peral. Ama-ejenti we-β-crystalline nuclileating aqinisekisa izinga lokushisa lemikhiqizo elishisayo lemikhiqizo ngenkathi lithuthukisa ukumelana nathi.
Izibonelo zemisebenzi yomkhiqizo kanye nokusetshenziswa kwama-nuclileating agents
| Imikhiqizo | Incazelo yomsebenzi | Izinja |
| I-ejenti esobala ye-nucreparing | Kungathuthukisa kakhulu ukuvela obala ye-resin, ukunciphisa i-haze ngaphezulu kuka-60%, Ngenkathi yandisa izinga lokushisa lokushisa nokushisa kwe-crystallization ye-resin ngo-5 ~ 10 ℃, kanye nokwenza ngcono i-modulus ye-Flempral nge-10% ~ 15%. Ibuye inciphise umjikelezo wokubumba, Ithuthukisa ukusebenza kahle kokukhiqizwa, futhi igcine ukuqina kobukhulu bomkhiqizo. | I-Poly Melt Index Polypropylene (noma i-polypropylene ephezulu) |
| I-Agent eqinile ye-nuclileing | Kungathuthukisa kakhulu izakhiwo zemishini ze-resin, Ngokwanda kwe-modulus ye-Flexiral kanye nokugoba amandla angaphezu kwama-20%, Kanye nokwanda kokushisa kokushisa kokushisa ngo-15 ~ 25 ℃. Kukhona futhi ukuthuthukiswa okuphelele nokulinganiselayo ezintweni ezahlukahlukene ezinjengokushisa kwe-crystallization kanye namandla omthelela, okuholela ekunciphiseni okulinganiselayo futhi kuncishiswe i-warpage deformation yomkhiqizo. | I-Polypropylene ephezulu, i-polyrpylene entsha ephakeme, ubulukhuni obuphakeme, kanye ne-polypropylene ephezulu, i-polypropylene yezicelo zezicelo ezi-autotive mncane |
| I-ejenti ye-β-crystalline eqinile | Kungakusiza ngempumelelo ukwakheka kwe-β-crystalline polypropylene, ngesilinganiso sokuguqulwa kwe-β-crystalline esingaphezu kwama-80%, ngcono kakhulu amandla okuphoqa we-polypropylene resin, Futhi ukuthuthukiswa kungafinyelela ngaphezu kwezikhathi ezi-3. | I-Polypropylene ephezulu, i-New High-Grividity High-gridicity, ukuqina okuphezulu, kanye ne-polyproplene ye-crystallization ephezulu, β-crystalline polypropylene |
