High ceev polyethylene: daim ntawv thov

Tsis tshua muaj ceev polyethylene yog ua los ntawm ib tug lim ethylene, thiab raws li ib tug organometallic catalyst protrude triethylaluminum thiab titanium tetrachloride. Rau polyethylene nyob rau hauv lub domestic kev lag luam siv ob peb kev siv technology tshiab variants uas txawv nyob rau hauv hom designs, lub reactor muaj peev xwm, txoj kev rau tu polyethylene rau lub catalyst siv.

technology

Feem ntau cov feem ntau nws nqa tawm peb sib law liag cov kauj ruam ntawm: polymerization ntawm ethylene, nws purification los ntawm cov catalyst thiab qhov kawg kom qhuav txheej txheem. Tom qab stirring daws ntawm triethylaluminum thiab titanium tetrachloride nyob rau hauv cyclohexane ntxiv thiab roj av. Rhuab mus rau 50 C ob-feem pua cov kua nkag mus rau lub reactor, qhov twg cov huab cua-nqa system ntawm ntxiv ethylene. Stirring txhawb loj ib feem ntawm ethylene rau polyethylene polymerization.

Yuav kom tshem tawm cov catalyst los ntawm lub resulting polymer twb lim tawm decomposition khoom thiab yaj. Lub polyethylene centrifuge ntxuav los ntawm lub catalyst siv methanol.

Polyethylene ntawm tsis tshua muaj siab tom qab muab yaug yog wrung tawm, thiab thereto yog ntxiv ib yam khoom rau kev txhim kho qhov zoo. Kom meej ntawm stabilizer siv, ethylene glycol thiab sodium nitrophosphate, thiab yuav ua rau nws shinier, ciab yog thov.

Thaum kawg, polyethylene yog raug kom qhuav thiab Granulation. Polyethylene ntawm tsis tshua muaj siab yog ua nyob rau hauv daim ntawv ntawm granules thiab hmoov.

Kav ua los ntawm cov uas tsis muaj kev ceev polyethylene

Lawv yog siv rau cov installation ntawm roj, phwj thiab dej systems.

Kav manufactured los ntawm tus nruam extrusion txoj kev. Raws li khoom raw rau zus tau tej cov polyethylene nyob rau hauv granules protrudes.

Kev lag kev luam tsim lub teb chaws siv xws li kav nyob rau hauv yuav luag tag nrho cov tshuab.

HDPE kav tsis adversely cuam tshuam cov dej zoo, vim hais tias cov sab hauv phab ntsa ntawm xeb yog tsis tsim thiab sau mineral ntsev.

Tsis tshua muaj siab polyethylene tau pom daim ntawv thov nyob rau hauv dej systems, vim nws yog resistant rau kev txhoj puab heev yam thiab rau siab kub.

Gas kav kuj tsis puas lawm thiab tsis txhob poob kev kawm thaj chaw rau ib tug ntev lub sij hawm.

Durability - superior zoo kav los ntawm HDPE. Lawv yog cov poob siab-resistant, tsis rot thiab ua tsis xeb, tsis txhob tawg nyob rau hauv tus ntawm siab thiab tsis muaj peevxwm. Lawv pab no ob peb decades.

Polyethylene High siab kuj mos mos thiab ywj. Nws khoom yog tus sib kho ntawm cov molecules uas feem ntau raug rau nws ceev. LDPE tsim ib tug ntau ntawm cov films. Lawv muaj ib tug heev zoo, thiab ntim khoom zoo kev xaiv no yog tias tej zaum yuav tsum tau pom. Nws preserves thiab txhawb nqa ib tug txheej ntawm zoo zog txawm nyob rau hauv kub txog li caum degrees. Zoo cov yam ntxwv ntawm lub polyethylene tsis hloov nyob rau hauv tus ntawm cov tshuaj. Nws yog tau nti cais tawm cov khoom ntawm dej thiab dej vapor.
