Isicelo somkhiqizo
I-3988 ikhuthaza i-resin crystallization ngokuhlinzeka nge-crystal nuclei, okwenza isakhiwo sekristalu sibe ngcono, ngaleyo ndlela sithuthukise ukuqina, izinga lokushisa lokuhlanekezela ukushisa, ukuzinza kwe-dimensional, obala kanye nesicwebezelisi somkhiqizo. Ngaphezu kwalokho, ama-nucleating transparent agents anganciphisa umjikelezo wokubumba umkhiqizo, andise izimo zokucubungula, futhi athuthukise ukushelela kwendawo yomkhiqizo.
I-3988 iyisizukulwane sesithathu se-sorbitol nucleating agent. Uma iqhathaniswa ne-DBS yesizukulwane sokuqala kanye ne-MDBS yesizukulwane sesibili, inokusebenziseka okungcono kwebhayoloji. Umkhiqizo awunabo ubuthi futhi awunaphunga, futhi ngesikhathi sokucubungula, awukhiqizi iphunga elingamukeleki kubantu abavamile. I-Nucleating transparent Agent 3988 ifaneleka ngokukhethekile ukusetshenziswa ku-resin yemikhiqizo ye-polypropylene yezinga eliphezulu, njengempahla yezokwelapha kanye nokupakishwa kokudla, futhi ifaneleka kakhulu ekwenzeni izinto zokupakisha ukudla kunesizukulwane sesibili.
I-3988 ifaneleka kakhulu ukukhiqiza imikhiqizo yepulasitiki esobala, njengempahla yezokwelapha, izimpahla zamasiko, ukupakishwa kwesiphuzo, izinkomishi ezibonisa izinto, izitsha, izitsha, amapuleti, amakesi e-CD, njll. Isebenza futhi emikhiqizweni yokubulala amagciwane emazingeni okushisa aphezulu futhi isetshenziswa kabanzi kumashidi e-PP asobala namashubhu. I-nucleating transparent agent 3988 ingasetshenziswa ngokuqondile ngokuxuba okomile ne-PP noma kwenziwe ku-2.5-5% masterbatch ngaphambi kokusetshenziswa. Ngokuvamile, inani elingeziwe le-nucleating transparency agent 3988 ku-0.2% kuya ku-0.4% linomphumela obaluleke kakhulu wokulwa nokungafihli. Inani elinconyiwe lokwengeza ngu-0.2 kuya ku-0.4%, futhi izinga lokushisa lokucubungula lingu-190 kuya ku-260℃.
Ukuphepha nokuvikelwa
Kufanele igcinwe endaweni epholile futhi eyomile. Ingagcinwa iminyaka emithathu ngaphansi kwezimo ezingavulwa. Uma umkhiqizo ungasetshenzisiwe, ukuvuleka kwesikhwama kufanele kuvalwe ngokuqinile.
