"Mellocecene" e bua ka mefulla e kopaneng ea meriana ea tšepe (joalo ka Zirconium, Titanium, Etc.) le Cycepentadiene. Polyproplene e hlophisitsoe hantle ka li-catalysts tsa Metallocene e bitsoa li-lallocene polypropingne (MPP).

Lihlahisoa tsa tšepe tsa tšepe (MPP) e na le phallo e phahameng, mocheso o phahameng, likhahla tse phahameng, tse ikhethang Tlhahiso ea Mellecene polypropiplene (MPP) e kenyelletsa mehato e mengata ea bohlokoa, ho kenyelletsa ho hlophisoa ha li-polyst

1. Tokisetso e Hlokahalang:

Khetho ea Metlacene Catalyst: Khetho ea Wanocene Catalyst e bohlokoa ho tsebiso ea thepa ea MPP e hlahisoang. Ka tloaelo li-catalysts tsena li kenyelletsa libaka tsa phetoho, joalo ka Zirconium kapa titanium, sandwich, e rotsitsoeng pakeng tsa cyclopentadienyl ligands.

Ho ekelletsa ka botlalo: hangata li-catalysts hangata li sebelisoa hammoho le cumalyst, hangata sehlopha sa aluminium se thehiloeng ho alum. Cocalystst e sebetsa ka mokhoa o hlakileng ea tšepe, e e lumellang ho qala karabelo ea polymeriation.

2. Polymerifization:

Ho itokisetsa: propur, Monotor, ea neng a e-na le Polypropylene, hangata e sebelisoa e le phepelo ea mantlha ea phepelo ea mantlha. Buka e hloekisitsoeng ho tlosa litšila tse ka u sitisang tšebetso ea polymerication.

Sethala sa Puseletso: Tsela ea polymemerication e etsahala sebakeng se setle tlasa maemo a laoloang ka hloko. Sethala sa Resume se kenyeletsa catalyst ea tšepe, cocallyst le additives tse ling tse hlokahalang bakeng sa thepa e lakatsehang e lakatsehang.

Maemo a polymerication: maemo a bosholu a kang mocheso, khatello ea mocheso le ho tlohela mosebetsi ka hloko le sebopeho se lakatsehang le sebopeho sa polymer. Li-catalys tsa tšepe li thusa tao e nepahetseng haholoanyane holim'a li-paramente tsena tse bapisoang le maemo ana a setso.

3. Copolymerization (ka boikhethelo):

Kakaretso ea Co-Monomirs: Maemong a mang, MPP e kanna ea qobella batho ba bang ba fetole thepa ea bona. Li-mocomers tse tloaelehileng li kenyelletsa ethylene kapa alpha-olefins tse ling. Ho kenyelletsa batho ba li-monomers ba lumelang ho etsa kopomer ea polymer bakeng sa lits'ebetso tse itseng.

4. Ho felisoa ha ho hlahlojoa:

Khetho ea karabelo: Hang ha setšoaeana se phethehile, karabelo e felisitsoe. Hangata sena se fihlella ka ho hlahisa moemeli oa ho felisoa e sebetsang le setulo se sebetsang sa Polymer e fela, ea emisa kholo e 'ngoe.

Joale phumo ea ponte e pholile ka potlako kapa ka bokhutšoaane ho thibela karabelo e 'ngoe le ho tiisa polymer.

5. Pholoso ea polymer le ho sebetsa ka poso:

Karolo ea Polymer: Polymer e aroloa le motsoako oa karabelo. Basomi ba sa laoleheng ha ba sa khonehe, matšeliso a ctalyst, 'me lihlahisoa tse ling li tlosoa ka mekhoa e mengata ea karohano.

Mehato ea ho sebetsa ka poso: MPP e ka ba le mehato e meng ea ho sebetsa, e kang ho etsoa, ​​e bentse le petetization, ho fihlela sebopeho le phepelo. Mehato ena e boetse e lumella ho kenyelletsa li-actives joaloka li-agentive, li-antioxidants, batsamaisi ba ho tiisa, li-coloratings tsa ts'ebetso.

Ho ntlafatsa MPP: Khanya e tebileng ka likarolo tsa bohlokoa tsa lisebelisoa tsa ho lokisa

Basebetsi ba Slip: Basebelisi ba thellang, joalo ka mafura a mangata a selemo ba selemo, hangata ba kenngoa ho MPP ho fokotsa khohlano lipakeng tsa lithunya tsa Pelikmer, ho thibela pele ho ts'ebetso. Sena se thusa ho ntlafatsa mekhoa e mengata ea ho fetoha le ho se bululetsoe.

Bacha ba phallang:Babusi ba phallang kapa ho lokisa AIDS, joalo ka polyethylene Waxes, ba sebelisetsoa ho ntlafatsa phallo ea MPP. Litšehetsi tsena li fokotsa setšoantšiso le ho ntlafatsa bokhoni ba Polymer ba ho tlatsa maspiti a polymetri ho tlatsa maspiti a polymetri ho tlatsa sesira sa bold, e bakoang hamolemo.

Antioxidants:

Stabilizers: Antioxidants ke lisebelisoa tsa bohlokoa tse sirelletsang basebetsi ba tsoang ho sopho ea ho senya. Ho silafatsa li-vahents.

Basebeletsi ba Nyane:

Basebeletsi ba sa tsitsang, ba joalo ka vucji kapa metsoako e meng ea ho khabisa sebopeho sa kristale se laetsoeng ho MPP. Ntlafatso ea lihlahisoa tsena e ntlafatsa thepa ea polytric mochini oa Polytric, ho kenyeletsoa le ho satalla le ho hanyetsa le ho hanyetsa.

Coloratonts:

Likoloea le Dyes: Hangata li-coloratont hangata li kenngoa ka mpp ho fihlela mebala e tobileng ea sehlahisoa sa ho qetela. Lipehelo le daes li khethoa ho latela litlhoko tsa 'mala o lakatsehang le tsa kopo.

Kamposi:

Li-elastomers: likopo moo ho tsitsisang ho matla ho bohlokoa, ho ka etsoa mosireletsi oa phello ea ethylene-propylene. Barekisi bana ba ntlafatsa ho thatafala ha polymer ntle le boitelo ho etsa lintho tse ling.

Litumello:

Li-grafts tsa maleic ayhydride: Likoloi li ka sebelisoa ho ntlafatsa phaello pakeng tsa MPP le li-polymer tse ling. Ka mohlala, Grafts e leng Malee ahydride e ka ntlafatsa phapano lipakeng tsa likarolo tse fapaneng tsa polymer.

Slip le li-antiblock tsa antiblock:

Lisebelisoa tsa ho thella: Ntle le ho fokotsa khohlano, li-agents tse nyane li ka sebetsa joalo ka li-agens tsa anti-block. Basebetsi ba antiblock ba thibela ho khomarela ha filimi kapa liaparo tsa pampiri nakong ea polokelo.

(Ho bohlokoa ho hlokomela hore litlatsetso tse ikhethang tsa ho sebetsa li ka fapana ka tšebeliso ea lihlahisoa tsa tšepe.

Ho notlolla katleho丨Litharollo tsa Melemo ea MPP: Karolo ea Litlaleho tsa Ts'ebetso ea Phatlalatso, E leng bahlahisi ba bolo ea MPP ba hloka ho tseba!

MPP e hlahile e le polymer ea ntlafatso, e fana ka thepa e ntlafalitsoeng le ts'ebetso e ntlafalitsoeng lits'ebetsong tse fapaneng. Leha ho le joalo, lekunutu la katleho ea lona ha lea ka la litšobotsi tsa lona tsa tlhaho empa le tšebeliso ea mekhoa ea ho sebetsa ka mokhoa o tsoetseng pele.
