Polypropylene twine yog qhov xav tau zoo hauv kev lag luam ntim khoom. Cov khoom no yog dab tsi thiab nws siv rau dab tsi? Wb sim to taub qhov teeb meem no.

Polypropylene twine - yog dab tsi?

Cov khoom no yog polypropylene, technical, zaj duab xis xov. Nws yog tsim los ntawm kev sib tw. Polypropylene twine yog qhov txhab ntawm lub pob zeb tshwj xeeb yam tsis muaj lub tes tsho.

Polypropylene khoom belongs rau chav kawm ntawm polyolefins. Nws yog cov khoom lag luam zoo ib puag ncig, muaj kev nyab xeeb tag nrho rau tib neeg kev noj qab haus huv thiab ib puag ncig. Yog li ntawd, polypropylene twine kuj yuav tsis ua mob. Nws ua li cas?

Kev tsim cov polypropylene twine

txheej txheem no tshwm sim hauv ntau theem:

1. Cov khoom siv raw - polypropylene - yog pub rau hauv lub hopper cia.
2. Los ntawm ntu no, cov granulate npaj tau nkag mus rau hauv qhov ziab kom qhuav. Qhov kub ntawm no yog tswj los ntawm 60 txog 110 degrees Celsius.
3. Tom qab ntawd cov khoom siv raw rov qab mus rau lub hopper cia, ces mus rau extruder.
4. Ntawm no cov polymer yog yaj, lim, ces muab rau lub taub hau extruder.
5. Nyob rau hauv daim ntawv ntawm lub vev xaib zaj duab xis, cov khoom nkag mus rau lub nruas txias. Ntawm no nws solidifies.
6. Tam sim no zaj movie no raug txiav ua ribbon.
7. Tom ntej no, cov txheej txheem ntawm rub cov kab xev hauv lub rooj sib tham yog ua tiav. Qhov no yog vim qhov sib txawv ntawm qhov sib txawv ntawm qhov thib ob thiab thawj xya-cov menyuam nyob rau hauv ib puag ncig ntawm cov cua kub txaus (qhov kub thiab txias nyob rau hauv qhov chaw taw qhia yog tsawg kawg yog 150 thiab siab tshaj 210 degrees Celsius).
8. Cov zaj duab xis daim kab xev ntawm lub fibrillator ua cov xov ntawm cov qauv mesh. Ces nws raug mob ntawm bobbins.

Daim ntawv thov khoom

Polypropylene twine tau nquag siv hauv kev lag luam hauv qab no:

• kev ua liaj ua teb;
• nqaij ua kev lag luam;
• rau kev tsim cov hlua nrog cov kab sib txawv;
• rau kev ntim khoom hauv tsev.

Hauv qee daim ntawv thov, cov khoom lag luam saum toj no muaj cov txiaj ntsig zoo. Cov neeg ua liaj ua teb nyiam khi bales ntawm straw nrog cov xov no. Cov kws tshaj lij tau sau tseg tias tus neeg uas pib siv polypropylene twine tsis zoo li yuav rov qab mus rau sisal.

Cov txiaj ntsig khoom

Polypropylene twine muaj cov yam ntxwv hauv qab no:

• siab tiv thaiv alkalis thiab acids;
• muaj cov khoom siv hluav taws xob zoo heev;
• tsis cuam tshuam los ntawm cov chiv chiv;
• txauskhoom siv nyiaj txiag;
• ua tiav kev nyab xeeb thiab tus phooj ywg ib puag ncig;
• nce productivity;
• nyab xeeb siv (piv txwv li, hlau lossis galvanized hlau tuaj yeem ua mob rau tib neeg txhais tes);
• txo qis tus nqi ntim khoom.

Ntxiv rau, cov khoom ntim no tsis rot thiab muaj fibrillation siab. Nws yog qhov yooj yim heev los tuav. Txawm hais tias, raws li cov kws tshaj lij sau tseg, cov xov polypropylene no muaj ib qho tsis zoo. Nws tawg thaum raug tshav ntuj. Tab sis qhov kev cuam tshuam zoo li no yuav tsum nyob ntev. Txawm li cas los xij, yog tias cov khoom tshwj xeeb tau ntxiv rau cov khoom ntim saum toj no thaum lub sij hawm tsim cov khoom ntim saum toj no, uas ua rau kom muaj zog thiab lub teeb nrawm, qhov teeb meem no raug tshem tawm.

Lwm qhov zoo ntawm cov xov polypropylene yog nws cov buoyancy siab. Nws kuj yog resistant rau dabtsi yog khoov thiab puas. Nws yog ib qho zoo heev dielectric, yooj yim heev rau lacing thiab tying.

Polypropylene twine, tus nqi uas yog 60% tsawg dua tus nqi ntawm cov xov hlau, nyob ntawm seb hom, tuaj yeem yuav rau 105-300 rubles. ib kilo.

Cov khoom no yog cov khoom ntim zoo heev. Cov yam ntxwv zoo heev ntawm cov xov polypropylene ua rau qhov kev thov siab rau nws.
