I-agent ye-Nucleating luhlobo lwesongezo esitsha esisebenzayo esinokuphucula izinto ezibonakalayo kunye nezomatshini zeemveliso ezifana nokungafihli, isicwebezelisi somphezulu, amandla okuqina, ukuqina, ubushushu bokutshintsha ubushushu, ukuchasana nempembelelo, ukuxhathisa, 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-nucleating agent yinto ephambili ekuveliseni i-resin ephezulu yokusebenza njenge-polypropylene ephezulu, i-high-rigidity, i-high-toughness, kunye ne-high-crystallinity polypropylene, i-β-crystalline polypropylene, kunye ne-polypropylene eguquliwe izicelo ezinodonga olubhityileyo. 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 zentsimbi ye-carboxylic acid, i-phosphate metal salts, i-sorbitol benzaldehyde derivatives, njl njl. Phakathi kwazo, i-sorbitol benzaldehyde derivatives okwangoku zezona zixhobo ezivuthiweyo ze-nucleating, kunye nokusebenza okugqwesileyo kunye namaxabiso aphantsi, kwaye ziye zaba zezona ziphuhliswayo, ezahlukeneyo. , kunye nohlobo olukhulu lwevolyum yee-agent ze-nucleating zombini ngaphakathi nangaphandle. 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 |
