I-agent ye-Nucleating luhlobo lwesongezelelo esitsha esisebenzayo esinokuphucula iimpawu zomzimba kunye noomatshini beemveliso ezifana nokungafihli, isicwebezelisi somphezulu, amandla okuqina, ukuqina, ubushushu bokuphazamisa ubushushu, ukuxhathisa impembelelo, ukuxhathisa kokukhasa, njl. Isetyenziswa ngokubanzi kwinkqubo yokuvelisa iiplastiki zekristale ezingaphelelanga ezifana ne-polyethylene kunye ne-polypropylene kwi-automotive, isixhobo sasekhaya, ukutya, i-electronics, kunye neendawo zonyango. Ngokomzekelo, i-agent ye-nucleating yinto ebalulekileyo ekuveliseni i-resin ephezulu yokusebenza njenge-polypropylene ephezulu ye-melt index, i-high-rigidity, i-high-toughness, kunye ne-high-crystallinity polypropylene, i-polypropylene ye-β-crystalline, kunye nezixhobo eziguquliweyo ze-polypropylene kwi-automotive thin-walled applications. Ngokudibanisa ii-agent ezithile ze-nucleating, ii-resin ezinokuphuculwa okuphuculweyo, ukuqina, kunye nokuqina kunokuveliswa. Ngokunyuka okubalulekileyo kwimveliso yasekhaya yepolypropylene ephezulu efuna ukongezwa kwee-agent ze-nucleating kunye nokukhula okukhawulezayo kwemfuno yokukhanya kwemoto kunye nezahluli zebhetri ye-lithium, kukho uphuhliso olukhulu olunokwenzeka kwimakethi ye-nucleating agent.
Kukho iintlobo ezininziii-nucleating agents, kunye nokusebenza kwabo kwemveliso kuyaqhubeka nokuphucula. Ngokweefom ze-crystal ezahlukeneyo ezibangelwa yi-nucleating agents, ziyakwazi ukwahlula zibe yi-α-crystalline nucleating agents kunye ne-β-crystalline nucleating agents. Kwaye i-α-crystalline nucleating agents inokuphinda ihlelwe kwiintlobo ze-inorganic, eziphilayo, kunye ne-polymer ngokusekelwe kwiiyantlukwano zabo zesakhiwo. Ii-inorganic nucleating agents ikakhulu zibandakanya ii-ajenti eziphuhliswe kwangethuba ze-nucleating ezifana ne-talc, i-calcium oxide, kunye ne-mica, ezingabizi kakhulu kwaye kulula ukuzifumana kodwa zinokucaca okulambathayo kunye neglosi yomphezulu. Izinto ze-nucleating ze-Organic ziquka iityuwa zensimbi ze-carboxylic acid, i-phosphate metal salts, i-sorbitol benzaldehyde derivatives, njl njl. Phakathi kwazo, i-sorbitol benzaldehyde derivatives okwangoku zezona zixhobo ze-nucleating ezivuthiweyo, kunye nokusebenza okugqwesileyo kunye namaxabiso aphantsi, kwaye ziye zaba zezona zixhobo ziphuhliswayo, ezahlukeneyo, kunye nodidi lwe-nucleating yasekhaya zombini kunye nobukhulu be-nucleating. I-polymer nucleating agents i-polymer nucleating agents ikakhulu i-high-melting-point polymeric nucleating agents, njenge-polyvinylcyclohexane kunye ne-polyvinylpentane. I-β-crystalline nucleating agents ikakhulu iqulethe iindidi ezimbini: inani elincinci leekhompawundi ze-polycyclic kunye nezakhiwo ze-quasi-planar, kunye nezo zenziwe nge-dicarboxylic acids kunye ne-oxides, i-hydroxides, kunye neetyuwa zetsimbi ezivela kwiQela le-IIA letafile ye periodic. I-β-crystalline nucleating agents iqinisekisa ukushisa kwe-thermal deformation yeemveliso ngelixa ziphucula ukuchasana kwazo.
Imizekelo yeMisebenzi yeMveliso kunye nosetyenziso lwee-Arhente zeNyukliya
| Iimveliso | Inkcazo yomsebenzi | Usetyenziso |
| Iarhente yeNyukliya eNgaphandle | Inokuphucula kakhulu ukungafihli ye-resin, ukunciphisa inkungu ngaphezu kwe-60%; ngelixa unyusa ubushushu bokutshintsha ubushushu kunye nobushushu becrystallization yeresin nge-5 ~ 10℃, kunye nokuphucula imodyuli eguquguqukayo nge-10% ~ 15%. Ikwanciphisa umjikelo wokubumba, iphucula ukusebenza kakuhle kwemveliso, kwaye igcina uzinzo lwemveliso. | High Melt Index Polypropylene (okanye High MI Polypropylene) |
| I-Arhente yokuQinisa iNyukliya | Inokuphucula kakhulu iipropathi zomatshini we-resin, ngokunyuka kwemodyuli eguquguqukayo kunye namandla okugoba ngaphezulu kwe-20%, kunye nokunyuka kobushushu bokuguqula ubushushu nge-15 ~ 25℃. Kukho uphuculo olubanzi kunye nolungelelwaniso kwimiba eyahlukeneyo efana nobushushu becrystallization kunye namandla empembelelo, okukhokelela ekuncipheni okulinganayo kunye nokunciphisa i-warpage deformation yemveliso. | I-High Melt Index Polypropylene, New High-Rigidity, High-Toughness, High-Crystallization Polypropylene, Modified Polypropylene Material for Automotive Thin-Wall Application. |
| I-β-Crystalline Toughening Nucleating Agent | Inokwenza ngokufanelekileyo ukwakheka kwe-β-crystalline polypropylene, ngesantya soguqulo se-β-crystalline esingaphezulu kwe-80%, ukuphucula kakhulu amandla empembelelo ye-polypropylene resin, kunye nokuphucula kunokufikelela ngaphezu kwamaxesha ama-3. | I-High Melt Index yePolypropylene, i-High-Rigidity entsha, i-High-Toughness, kunye ne-High-Crystallization Polypropylene, i-β-Crystalline Polypropylene |
