I-Nucleating agent luhlobo lwesongezo esitsha esisebenzayo esinokuphucula iipropati zomzimba nezoomatshini zeemveliso ezinje ngokucaca, ukuqaqamba komphezulu, amandla okutsalwa, ubulukhuni, ubushushu bokujika kobushushu, ukumelana nempembelelo, ukumelana nokuqhekeka, njl. ngokutshintsha indlela yokwenza i-crystallization yee-resins. Isetyenziswa kakhulu kwinkqubo yokuvelisa iiplastiki ezi-crystalline ezingaphelelanga ezifana ne-polyethylene kunye ne-polypropylene kwiimoto, izixhobo zasekhaya, ukutya, izixhobo ze-elektroniki, kunye nezonyango. Umzekelo, i-nucleating agent sisixhobo esibalulekileyo ekuvelisweni kwee-resins ezisebenzayo eziphezulu ezifana ne-polypropylene enyibilikayo kakhulu, ubulukhuni obuphezulu, kunye ne-polypropylene ephezulu, i-polypropylene ye-β-crystalline, kunye nezinto ze-polypropylene ezilungisiweyo kwizicelo ze-automotive thin-walled. Ngokongeza ii-arhente ezithile ze-nucleating, ii-resins ezinobulukhuni obuphuculweyo, ubulukhuni, kunye nokuqina zinokuveliswa. Ngenxa yokwanda okukhulu kwimveliso yasekhaya ye-polypropylene esebenza kakhulu efuna ukongezwa kwee-nucleating agents kunye nokukhula ngokukhawuleza kwemfuno yezibane zemoto kunye nezahluli zebhetri ye-lithium, kukho ithuba elikhulu lophuhliso kwimarike yee-nucleating agents.
Kukho iintlobo ezininzi zeiiarhente ze-nucleating, kwaye ukusebenza kwemveliso yazo kuyaqhubeka nokuphucuka. Ngokweefom ezahlukeneyo zekristale ezibangelwa ziiarhente ze-nucleating, zinokwahlulwa zibe ziiarhente ze-nucleating ze-α-crystalline kunye neearhente ze-nucleating ze-β-crystalline. Kwaye iiarhente ze-nucleating ze-α-crystalline zinokuhlulwahlulwa ngakumbi zibe ziintlobo ze-inorganic, ze-organic, kunye neze-polymer ngokusekwe kumahluko azo ekwakhiweni. Iiarhente ze-nucleating ze-inorganic ziquka iiarhente ze-nucleating eziphuhliswe kwangoko ezifana ne-talc, i-calcium oxide, kunye ne-mica, ezingabizi kakhulu kwaye kulula ukuzifumana kodwa zinokubonakala okungalunganga kunye ne-surface gloss. Iiarhente ze-nucleating ze-organic ziquka ikakhulu iityuwa ze-carboxylic acid metal, iityuwa ze-phosphate metal, ii-sorbitol benzaldehyde derivatives, njl. Phakathi kwazo, ii-sorbitol benzaldehyde derivatives okwangoku zezona arhente ze-nucleating ezivuthiweyo, ezisebenza kakuhle kakhulu kunye namaxabiso aphantsi, kwaye ziye zaba luhlobo lweearhente ze-nucleating eziphuhliswe kakhulu, ezahlukeneyo, kwaye zinomthamo omkhulu kakhulu ngaphakathi nakwamanye amazwe. Iiarhente ze-nucleating ze-polymer ikakhulu ziiarhente ze-nucleating ze-polymeric ezinamaqondo aphezulu okunyibilika, ezifana ne-polyvinylcyclohexane kunye ne-polyvinylpentane. Ii-β-crystalline nucleating agents ikakhulu ziqulathe iintlobo ezimbini: inani elincinci lee-polycyclic compounds ezinezakhiwo ze-quasi-planar, kunye nezo zenziwe zii-dicarboxylic acids kunye nee-oxides ezithile, ii-hydroxides, kunye neetyuwa zeemetals ezivela kwiQela le-IIA letafile yexesha. Ii-β-crystalline nucleating agents ziqinisekisa ubushushu bokuguqulwa kobushushu beemveliso ngelixa ziphucula ukumelana kwazo nempembelelo.
Imizekelo yeMisebenzi yeMveliso kunye nokusetyenziswa kweeNucleating Agents
| Iimveliso | Inkcazo yomsebenzi | Izicelo |
| I-Arhente yeNucleating engabonakaliyo | Ingaphucula kakhulu ukucaca kwezinto ye-resin, inciphisa inkungu ngaphezulu kwama-60%, ngelixa kunyusa ubushushu obutshintsha ubushushu kunye nobushushu bekristale ye-resin ngo-5 ~ 10℃, kunye nokuphucula i-flexural modulus nge-10% ~ 15%. Ikwanciphisa umjikelo wokubumba, iphucula ukusebenza kakuhle kwemveliso, kwaye igcina uzinzo olulinganayo lwemveliso. | I-Polypropylene eNcibilikayo ePhakamileyo (okanye iHigh MI Polypropylene) |
| I-Arhente yeNucleating eqinileyo | Ingaphucula kakhulu iipropati zoomatshini ze-resin, kunye nokwanda kwe-flexural modulus kunye namandla okugoba angaphezu kwama-20%, kunye nokunyuka kobushushu obutshintsha ubushushu nge-15~25℃. Kukwakho nophuculo olupheleleyo nolulinganiselayo kwiinkalo ezahlukeneyo ezifana nobushushu bekristale kunye namandla empembelelo, okubangela ukushwabana okulinganayo kunye nokuncipha kokuguquguquka kwe-warpage yemveliso. | I-High Melt Index Polypropylene, i-New High-Rigidity, i-High-Toughness, kunye ne-High-Crystallization Polypropylene, i-Modified Polypropylene Material ye-Automotive Thin-Wall Applications |
