Twine polypropylene: daim ntawv thov, qhov zoo

Twine polypropylene yog tshwj xeeb tshaj yog nyob rau hauv coob nyob rau hauv kev ua lag luam ntawm lub ntim cov ntaub ntawv. Yuav ua li cas yog khoom no thiab dab tsi yog ua ntawv thov? Wb sim txheeb tawm qhov teeb meem no.

Twine polypropylene - yog dab tsi?

Cov khoom no yog ib tug filament polypropylene, technical, zaj duab xis. Nws yog tsim los ntawm Torsion. Polypropylene twine yog lub qhov txhab nyob rau hauv ib tug spool tsis muaj ib tug tshwj xeeb lub tes tsho.

Polypropylene cov ntaub ntawv uas belongs rau lub chav kawm ntawv ntawm polyolefins. Nws yog tus phooj ywg environmentally, kev ruaj ntseg kiag rau tib neeg noj qab haus huv thiab ib puag ncig. Yog li ntawd, polypropylene twine thiab ua tsis muaj teebmeem. Yuav ua li cas nws yog ua?

Qhuav ntawm polypropylene twine

Qhov no txoj kev yuav siv sij hawm qhov chaw nyob rau hauv ob peb theem:

1. Cov sau hopper nkag raw cov ntaub ntawv - polypropylene.
2. Los ntawm no department hauv lub tiav lawm granulate nkag mus rau hauv qhuav compartment. Qhov kub yog tswj ntawm 60 mus rau 110 degrees Celsius.
3. Ces tus raw khoom mus rov qab mus rau hauv lub tank cia, thiab lwm yam - nyob rau hauv ib tug extruder.
4. Ntawm no, cov polymer yog melted, lim, thiab ces noj rau ntawm txoj kev lub taub hau ntawm lub extruder.
5. Nyob rau hauv daim ntawv ntawm cov zaj duab xis web khoom noj mus rau ib tug txias nruas. Qhov uas nws solidifies.
6. Ces tus zaj duab xis yog txiav mus rau hauv ribbons.
7. Ntxiv ncab txheej txheem yog nqa tawm nyob rau hauv lub chamber ribbons orientation. Qhov no tshwm sim vim qhov txawv ntawm tus thawj thiab thib ob speeds nyob rau hauv ib tug nruab nrab semivaltsev txaus huab cua kub (nyob rau hauv lub orientation ntawm lub chamber kub yog tsawg kawg yog 150 thiab nyob 210 degrees Celsius).
8. Rau daim kab xev ntaub ntawv ib tug zaj duab xis nyob fibrillyatore filament lev qauv. nws yog ces lub qhov txhab mus rau Spools.

khoom Daim ntawv thov

Twine polypropylene yog dav siv nyob rau hauv cov nram no industries:

• ua liaj ua teb;
• nqaij ua lag luam;
• rau zus tau tej cov ropes nrog txawv diameters;
• rau lub ntim rau tsev neeg lub hom phiaj.

Nyob rau hauv ib co industries ua ntawv thov cov saum toj no cov khoom muaj kev zoo. Qhov no ntim xov teb xav kom khi straw bales. Kws txawj nco ntsoov tias ib tug neeg uas tau siv polypropylene twine, kog puas rov los sisal.

khoom pab cuam

Twine polypropylene yog tsiag ntawv los ntawm cov nram qab no nta:

• High kuj mus alkalis thiab acids;
• Nws muaj zoo heev thermal rwb thaiv tsev zog;
• tsis tus organic chiv;
• sufficiently yig cov khoom;
• kev ruaj ntseg kiag thiab environmentally phooj ywg;
• kom tsim tau;
• kev nyab xeeb siv (piv txwv li, steel los yog galvanized hlau yuav ua kev puas tus tib neeg txhais tes);
• ho cov nqi ntawm ntim.

Nyob rau hauv tas li ntawd, lub ntim khoom yuav raug lwj thiab muaj high fibrillation. Nws yog heev yooj yim mus siv. Txawm tias, raws li kws txawj nco ntsoov, qhov no polypropylene xov muaj ib drawback. Nws yog muab los ntawm tshav ntuj. Tab sis xws li cawv yuav tsum mus. Txawm li cas los, yog hais tias tus siv ntawm lub ntim khoom ntawm saum toj no tej yam tau ntxiv rau nws cov muaj pes tsawg leeg, uas ua rau kom cov durability thiab lub teeb fastness, qhov teeb meem no yog tshem tawm.

Lwm zoo dua ntawm polypropylene xov yog nws cov high buoyancy. nws tseem yog resistant rau flexing thiab puas. Yog ib qho zoo heev insulator, nws yog heev yooj yim thaum koj hlua thiab luas.

Twine polypropylene, uas raug nqi 60% tsawg tshaj li tus nqi ntawm nws yog xim hlau xov, nyob ntawm seb lub hom yuav yuav rau 105-300 rubles. ib kilogram.

Cov khoom no yog ib qho zoo heev ntim khoom. Rau yav tom ntej kev yam ntxwv ntawm polypropylene xov ua rau kom lub siab thov rau nws.
