Uzalishaji thabiti wa metallocene polyethilini!

On November 6th, the reporter learned from Dushanzi Petrochemical Company that the domestic catalyst was used to produce metallocene polyethylene mHD3702 products in the condensed state for the first time in the 22 nd line of the company's polyethylene plant, which broke the dependence on imported catalysts in the past and realized the independent development of a full range of metallocene polyethylene products with domestic vichocheo. Dushi petrochemical pia imekuwa biashara ya kwanza nchini China kufanikiwa kutengeneza bidhaa za metallocene polyethilini MHD3702 kwa kutumia vichocheo vya ndani katika hali iliyofupishwa.

Bidhaa za metallocene polyethilini zina mali bora, na zinajulikana kama 'laini ya dhahabu ' katika plastiki. Ni 'vitu vya moto ' katika soko la mwisho la polyolefin, na pia ni mwelekeo muhimu wa maendeleo wa uingizwaji wa vifaa vya resin nchini China. Katika miaka ya hivi karibuni, na uboreshaji wa kiwango cha jumla cha tasnia ya kemikali ya ndani, biashara zingine kubwa za kemikali zina uwezo wa kutengeneza polyethilini ya metallocene kwa kutumia vichocheo vilivyoingizwa. Walakini, maendeleo ya muda mrefu ya biashara ni mdogo na bei kubwa ya vichocheo vilivyoingizwa na kutofaulu teknolojia ya msingi ya uzalishaji.

In order to fully master the 'palace-level' technology of producing metallocene polyethylene products in the chemical industry and fill the domestic gap, Dushi Petrochemical began research and development in 2015. After unremitting efforts, in December 2022, qualified metallocene polyethylene products were successfully produced by using chromium powder as seed bed and domestic catalyst, becoming the first enterprise in China to realize Uzalishaji mkubwa, wa serial na thabiti wa vifaa maalum vya filamu ya metallocene polyethilini.

Mnamo Mei 23 mwaka huu, duru ya kwanza ya ubadilishaji wa kichocheo cha ndani cha Metallocene huko Sinopec ilianza rasmi. Siku kumi na moja baadaye, Sinopec ilizalisha zaidi ya tani 3,000 za bidhaa za metallocene polyethilini MLL1018, na kisha bidhaa za Metallocene MLL2010 na MHD3702 zilibadilishwa kwa mafanikio. Baada ya ukaguzi wa sampuli, bidhaa zote zina sifa.

Kwa sasa, Dushi petrochemical ndio biashara pekee nchini China ambayo imegundua utengenezaji wa filamu ya metallocene polyethilini, ikivunja ukiritimba wa bidhaa za nje za mwisho na kugundua badala ya malighafi. Uuzaji wa bidhaa kama vile HPR1018HA na kiwango cha EZP2010Ha kwanza nchini China. Bidhaa hizo zina mali bora ya mitambo na macho, na hutumiwa sana kutengeneza filamu za FFS, filamu za ufungaji wa chakula, filamu za kumwaga, filamu inayoweza kusongeshwa na kadhalika.
